Description

Channel transmission method and related equipment
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a channel transmission method and related devices.
Background
In the Fifth Generation (5G) communication system, a Multi-transmission point (Multi-transmission and reception point, multi-TRP) transmission technology is a key technology for improving overall performance of the system and solving the inter-cell interference problem. The Multi-TRP transmission technology comprises a plurality of schemes such as a joint transmission technology, a dynamic transmission point selection technology, cooperative scheduling and the like in an implementation manner.
Currently, in a Multi-TRP transmission technology, a plurality of network devices are allowed to respectively send different downlink control information to the same terminal device, so that the terminal device can respectively send corresponding physical uplink control channels (Physical Uplink Control Channel, PUCCH) and physical uplink shared channels (Physical Uplink Share Channel, PUSCH) to corresponding network devices according to each downlink control information. Since real-time information interaction cannot be performed among the plurality of TRPs, UCI information carried on the PUCCH or the PUSCH is expected to be sent to corresponding network equipment in real time. However, when the terminal device transmits PUCCH and PUSCH to different network devices, there is a case where the resources of the plurality of PUCCH and PUSCH overlap, and therefore, how to transmit these uplink channels when the plurality of PUCCH and PUSCH overlap is a problem to be solved.
Disclosure of Invention
The application provides a channel transmission method and related equipment, which can transmit at least one uplink channel under the condition that resources occupied by a plurality of uplink channels overlap.
In a first aspect, the present application provides a channel transmission method, where a terminal determines that a resource occupied by a first uplink shared channel overlaps a resource occupied by a second uplink control channel, and the terminal may send at least one of the first uplink shared channel and the second uplink control channel. Therefore, the channel transmission method can realize the transmission of at least one uplink channel when the resources occupied by a plurality of uplink channels are overlapped in the coordinated multi-point transmission, and is beneficial to avoiding the waste of transmission resources caused by the incapability of transmitting all overlapped uplink channels, thereby enabling at least one of the network equipment corresponding to the first uplink shared channel and the network equipment corresponding to the second uplink control channel to acquire the uplink control information.
In an alternative embodiment, the terminal transmitting at least one of the first uplink shared channel and the second uplink control channel may include: and the terminal sends the first uplink shared channel and the second uplink control channel. And transmitting the first uplink shared channel and the second uplink control channel, wherein the resources occupied by the first uplink shared channel are subjected to punching processing. The resources occupied by the second uplink control channel and the resources occupied by the demodulation reference signals (Demodulation Reference Signal, DMRS) corresponding to the first uplink shared channel are not overlapped, the total bit number of the bearing information of the second uplink control channel is smaller than or equal to a first preset threshold value, and the terminal adopts a mode of punching holes on the resources occupied by the first uplink shared channel to send the first uplink shared channel and the second uplink control channel.
In another alternative embodiment, the sending, by the terminal, at least one of the first uplink shared channel and the second uplink control channel may include: and the terminal transmits one of the first uplink shared channel and the second uplink control channel. And the resources occupied by the second uplink control channel are overlapped with the resources occupied by the demodulation reference signals corresponding to the first uplink shared channel, or the total bit number of the bearing information of the second uplink control channel is larger than the first preset threshold value, and the terminal sends one of the first uplink shared channel and the second uplink control channel.
As can be seen, in the above two embodiments, when the resources occupied by the second uplink control channel and the resources occupied by the DMRS corresponding to the first uplink shared channel do not overlap, that is, the second uplink control channel does not affect the DMRS corresponding to the first uplink shared channel, and the total number of bits of the information carried by the second uplink control channel is less than or equal to the first preset threshold, the terminal may both send the two overlapped uplink channels; and the second uplink control channel affects the DMRS corresponding to the first uplink shared channel, or when the total bit number of the information carried by the second uplink control channel is greater than the first preset threshold, one of the two overlapped uplink channels may be sent. Thus, the two embodiments described above facilitate the terminal to feed back uplink control information (Uplink control information, UCI) carried by at least one uplink channel.
The first preset threshold may be a total number of bits of information carried by a preset uplink control channel. The first preset threshold may be 2bits or 4bits, etc. The first preset threshold may be configured according to requirements.
In this case, the terminal may determine whether to adopt a puncturing manner so as to transmit the first uplink shared channel and the first uplink control channel, in consideration of whether the resources occupied by the second uplink control channel overlap with the resources occupied by the DMRS corresponding to the first uplink shared channel. In another case, the terminal may consider whether the transmission power of the resource position overlapping between the resource occupied by the uplink control channel and the resource occupied by the uplink shared channel exceeds the maximum transmission power, and if the transmission power exceeds the maximum transmission power, the terminal may not consider "multiplexing", and may select one channel to transmit; if the maximum transmit power is not exceeded, the precondition for the first case described above may be further considered. Therefore, the precondition of the second case can avoid that the transmission power is too small after the resources occupied by the uplink shared channel are punctured, so that the uplink shared channel cannot be received.
In an alternative embodiment, the terminal transmits one of the first uplink shared channel and the second uplink control channel. In an optional embodiment, the sending, by the terminal, one of the first uplink shared channel and the second uplink control channel may include: the terminal does not send the first uplink shared channel and sends the second uplink control channel; or the terminal sends the first uplink shared channel and does not send the second uplink control channel. The information borne by the second uplink control channel comprises hybrid automatic repeat request acknowledgement information HARQ-ACK, the terminal does not send the first uplink shared channel, and the second uplink control channel is sent; and the information carried by the second uplink control channel does not contain HARQ-ACK, and the terminal sends the first uplink shared channel and does not send the second uplink control channel. It can be seen that, in this embodiment, on one hand, the terminal is facilitated to preferentially send HARQ-ACK to the network device, and on the other hand, the terminal is facilitated to preferentially send UCI information and/or data carried by the uplink shared channel to the network device.
In a second aspect, the present application further provides a channel transmission method, where in the channel transmission method, a resource occupied by a first uplink shared channel overlaps with a resource occupied by a second uplink control channel, the resource occupied by the first uplink shared channel overlaps with the resource occupied by the first uplink control channel, and the first uplink shared channel is associated with the first uplink control channel; in this case, the terminal may determine the transmission scheme of the first uplink shared channel and the first uplink control channel. For example, the timing condition is not satisfied between the first uplink shared channel and the first uplink control channel, the terminal does not transmit the first uplink shared channel, and transmits the first uplink control channel and the second uplink control channel; the terminal multiplexes part or all of the information carried by the first uplink shared channel with the information carried by the first uplink shared channel when the time sequence condition is satisfied between the first uplink shared channel and the first uplink control channel, carries the multiplexed information on the first uplink shared channel, and performs the above step of transmitting at least one of the first uplink shared channel and the second uplink control channel.
As can be seen, in this embodiment, when determining to transmit the first uplink shared channel, the resources occupied by the first uplink shared channel overlap with the resources occupied by the first uplink control channel, and then at least one of the first uplink shared channel and the second uplink control channel is transmitted, with respect to overlapping the resources occupied by the first uplink shared channel and the resources occupied by the second uplink control channel; in addition, in this embodiment, part or all of the information in the first uplink control channel bearer information may be multiplexed with the information carried by the first uplink shared channel, so that UCI information carried by the overlapped uplink channel is sent to each network device as much as possible.
In the channel transmission method, the multiplexing, by the terminal, part or all of the information carried by the first uplink control channel with the information carried by the first uplink shared channel may include any one of the following embodiments. For example, the terminal multiplexes HARQ-ACK included in the first uplink control channel bearer information with information carried by the first uplink shared channel by punching on a resource of the first uplink shared channel, where the number of bits of HARQ-ACK included in the first uplink control channel bearer information is less than or equal to a second preset threshold; or the terminal multiplexes the HARQ-ACK contained in the first uplink control bearer information with the information borne by the first uplink shared channel in a rate matching manner, where the number of bits of the HARQ-ACK contained in the first uplink control bearer information is greater than the second preset threshold;
Or the terminal multiplexes the channel state information contained in the first uplink control channel bearing information with the information borne by the first uplink shared channel in a rate matching manner, wherein the information borne by the first uplink shared channel does not contain the channel state information;
or the terminal multiplexes the channel state information except the periodic channel state information contained in the first uplink control channel carrying information with the information carried by the first uplink shared channel in a rate matching manner, wherein the information carried by the first uplink shared channel contains the channel state information.
The second preset threshold may be a preset number of bits of HARQ-ACK. The second preset threshold may be 2bits. The second preset threshold may be configured according to requirements.
In an optional implementation manner, in a first aspect, the terminal sends one of the first uplink shared channel and the second uplink control channel, and in the channel transmission method in this second aspect, the method may include the following steps: the terminal does not send the first uplink shared channel and sends the second uplink control channel, wherein the priority of the first uplink shared channel bearing information is lower than or equal to the priority of the second uplink control channel bearing information; or the terminal sends the first uplink shared channel and does not send the second uplink control channel, wherein the priority of the first uplink shared channel bearing information is higher than or equal to the priority of the second uplink control channel bearing information. Since in this aspect, the HARQ-ACK included in the first uplink control channel bearer information may be carried by the first uplink shared channel, this embodiment is advantageous for transmitting the information with the highest priority to the network device based on the comparison of priorities.
For example, the priority of the information carried by the first uplink shared channel is determined by the information with the highest priority among the information carried by the first uplink shared channel; the priority of the information carried by the second uplink control channel is determined by the information with the highest priority in the information carried by the second uplink control channel. That is, in the second aspect, the information carried by the first uplink shared channel may include at least one of hybrid automatic repeat request acknowledgement information HARQ-ACK and channel state information; the information carried by the second uplink control channel comprises at least one uplink control information of hybrid automatic repeat request acknowledgement information (HARQ-ACK) and channel state information; wherein the priority of the HARQ-ACK is higher than the priority of the channel state information. Therefore, this embodiment is advantageous in transmitting the uplink control information with high priority to the network device based on the comparison of the priorities.
The channel state information carried by the first uplink control channel may include periodic channel state information (periodic channel state information, P-CSI), semi-static channel state information (semi-persistent channel state information, semi-CSI), etc. The channel state information carried by the second uplink shared channel may include semi-static channel state information (semi-CSI), aperiodic channel state information (aperiodic channel state information, AP-CSI). The semi-static channel state information (semi-CSI) is configured on which channel of the uplink control channel and the uplink shared channel is transmitted, and UCI information carried by which channel may include the semi-CSI.
In an alternative embodiment, the priority of the HARQ-ACK is higher than the priority of the channel state information, so that the HARQ-ACK can be fed back to the network device as soon as possible. In another alternative embodiment, the priority of the HARQ-ACK may be lower than the priority of the channel state information, so that the channel state information can be fed back to the network device as soon as possible. Thus, embodiments of the present application do not limit the priority of both, and may be specifically predefined or configured in conjunction with an application scenario.
In an alternative embodiment, the priority among the AP-CSI, the P-CSI, the semi-CSI carried on the first uplink shared channel, and the semi-CSI carried on the first uplink control channel may be: the priority of the AP-CSI is higher than the priority of semi-CSI carried on an uplink shared channel; "priority of semi-CSI carried on uplink shared channel" is higher than "priority of semi-CSI carried on uplink control channel"; the "priority of semi-CSI carried on uplink control channel" is higher than the "priority of P-CSI". Therefore, in the first aspect and the second aspect, when the information carried by the first uplink control channel is multiplexed with the information carried by the first uplink shared channel, P-CSI in the first uplink control carrying information may not be multiplexed, i.e., the P-CSI is discarded, so that the occupation proportion of the multiplexing mode to the resources of the first uplink shared channel is reduced while UCI information with higher priority is sent to the network device.
In another alternative embodiment, the priority of each channel state information may be predefined or configured correspondingly according to the application scenario. The embodiments of the present application are not limited.
In an alternative embodiment, the priority of the first uplink shared channel carrying information is determined by whether the first uplink shared channel carries hybrid automatic repeat request acknowledgement information HARQ-ACK; the priority of the second uplink control channel carrying information is determined by whether the second uplink control channel carries hybrid automatic repeat request acknowledgement information HARQ-ACK. Therefore, the embodiment is beneficial to transmitting the HARQ-ACK with high priority to the network equipment based on the comparison of the priority, so as to quickly retransmit the wrong data.
In this embodiment of the present application, whether the first uplink control channel is associated with the first uplink shared channel may be determined by whether the downlink control related parameters corresponding to the respective channels are the same.
The uplink control channel is associated with the uplink shared channel, which means that the uplink control channel and the uplink shared channel are sent to the same network device; correspondingly, the uplink control channel and the uplink shared channel are not associated, which means that the uplink control channel and the uplink shared channel are respectively sent to different network devices.
In a third aspect, the present application further provides a channel transmission method, where the channel transmission method is different from the channel transmission method described in the two aspects, and in the channel transmission method, a resource occupied by a first uplink control channel overlaps a resource occupied by a first uplink shared channel; the first uplink control channel is associated with the first uplink shared channel; correspondingly, the terminal transmits one of the first uplink shared channel and the first uplink control channel.
In this aspect, an optional implementation manner of "the terminal transmits one of the first uplink shared channel and the first uplink control channel" may refer to the related content of the above second aspect. For example, the sending, by the terminal, one of the first uplink shared channel and the first uplink control channel may include: the terminal multiplexes part or all of information in the first uplink control channel bearing information with information borne by the first uplink shared channel and bears the information on the first uplink shared channel, and further, the terminal can send the first uplink shared channel and not send the first uplink control channel, wherein a time sequence condition is met between the first uplink control channel and the first uplink shared channel; or the terminal does not send the first uplink shared channel, and sends the first uplink control channel, wherein the first uplink control channel and the first uplink shared channel do not meet a time sequence condition. In addition, how part or all of the information carried by the first uplink control channel is multiplexed with the information carried by the first uplink shared channel may also refer to the related content of the above second aspect, which is not described in detail herein.
In a fourth aspect, the present application further provides a channel transmission method, where, compared with the channel transmission method of the third aspect, resources occupied by a first uplink control channel overlap with resources occupied by a first uplink shared channel, and resources occupied by the first uplink shared channel overlap with resources occupied by the second uplink control channel; in this way, the terminal overlaps the resources occupied by the first uplink control channel with the resources occupied by the first uplink shared channel, transmits one of the first uplink shared channel and the first uplink control channel, and determines the transmission schemes of the first uplink shared channel and the second uplink control channel with respect to the overlapping of the resources occupied by the first uplink shared channel and the resources occupied by the second uplink control channel.
For example, the terminal punches a hole on a resource that is occupied by the first uplink shared channel and a resource that is occupied by the second uplink control channel, and sends the second uplink control channel, and performs the operation of sending one of the first uplink shared channel and the first uplink control channel according to the third aspect, where the resource that is occupied by the second uplink control channel and the resource that is occupied by the demodulation reference signal corresponding to the first uplink shared channel do not overlap, and the total bit number of the information carried by the second uplink control channel is less than or equal to a second preset threshold; or,
The terminal does not send the first uplink shared channel, and sends the second uplink control channel and the first uplink control channel, wherein the resources occupied by the second uplink control channel overlap with the resources occupied by the demodulation reference signals corresponding to the first uplink shared channel, and the information carried by the second uplink control channel contains HARQ-ACK, or,
the total bit number of the information carried by the second uplink control channel is larger than the preset threshold value, and the information carried by the second uplink control channel contains HARQ-ACK; or,
and the terminal does not send the second uplink control channel, and executes the operation of sending one of the first uplink shared channel and the first uplink control channel according to the third aspect, wherein the resources occupied by the second uplink control channel overlap with the resources occupied by the demodulation reference signals in the first uplink shared channel and the information borne by the second uplink control channel does not contain HARQ-ACK, or the total bit number of the information borne by the second uplink control channel is greater than the preset threshold and the information borne by the second uplink control channel does not contain HARQ-ACK.
In a fifth aspect, the present application further provides a channel transmission method, where implementation conditions of the above-mentioned alternative transmission scheme are not agreed between a terminal and a network device, that is, the terminal determines an uplink channel transmission mode when the first uplink shared channel overlaps with both the first uplink control channel and the second uplink control channel, and the network device side does not know how the terminal will transmit the uplink channel.
For example, the terminal may send the first uplink control channel and the second uplink control channel, respectively, without sending the first uplink shared channel; or the terminal multiplexes part or all of the information in the first uplink control channel bearing information with the information borne by the first uplink shared channel, bears the information on the first uplink shared channel, and then sends at least one of the first uplink shared channel and the second uplink control channel according to the optional rule, such as the channel transmission method in the first aspect, where the first uplink control channel and the first uplink shared channel meet the time sequence condition.
In the above example, when determining that the second uplink control channel includes HARQ-ACK, the terminal may perform the above steps of transmitting the first uplink control channel and the second uplink control channel, respectively, without transmitting the first uplink shared channel.
Correspondingly, for the network device side, the first uplink control channel and the network device corresponding to the first uplink shared channel do not know the transmission scheme selected by the terminal, so the information carried by the first uplink control channel can be detected twice, that is, the first uplink control channel is detected on the resources of the first uplink control channel respectively, if the detection fails, the first uplink shared channel is detected on the resources of the first uplink shared channel, and the detected first uplink shared channel also carries the multiplexed information carried by the first uplink control channel. Specifically, the operation of the network device side can be seen from the following sixth and seventh aspects, corresponding to the channel transmission methods of the first to fifth aspects.
In a sixth aspect, the present application further provides a channel transmission method, where the channel transmission method is illustrated from a perspective of a network device side.
In the channel transmission method according to the first to fifth aspects, when the resources occupied by the second uplink control channel overlap with the resources occupied by the first uplink shared channel, for example, TRP2, the terminal does not transmit the second uplink control channel, and in another case, the terminal transmits the second uplink control channel by puncturing on the resources of the first uplink shared channel, and in yet another case, the terminal transmits the second uplink control channel. Thus, for TRP2, either normal reception is successful or reception is failed, and thus TRP2 does not require the addition of other modes of operation.
For the channel transmission methods of the first to fifth aspects, the association between the first uplink control channel and the first uplink shared channel may correspond to the same network device, for example TRP1, where when the resources occupied by the first uplink control channel overlap with those occupied by the first uplink shared channel, in one case, the terminal does not send the first uplink control channel, but multiplexes part or all of the information in the first uplink control channel bearer information with the information carried by the first uplink shared channel, and carries the multiplexed information on the first uplink shared channel, and sends the first uplink shared channel; in another case, the terminal does not transmit the first uplink shared channel and transmits the first uplink control channel. Thus, for TRP1, either the first uplink control channel is received on the resources of the first uplink control channel, but the first uplink shared channel is not received; or the first uplink control channel is not received, the first uplink shared channel is received, and the first uplink shared channel carries part or all of the information in the first uplink control channel carrying information. Accordingly, the channel transmission method described in this aspect is described below from the perspective of TRP 1.
In the channel transmission method, network equipment receives a first uplink control channel on resources of the first uplink control channel; the network equipment receives a first uplink shared channel on the resource of the first uplink shared channel; the network equipment acquires uplink control information; the uplink control information is from the first uplink control channel or from the first uplink shared channel; and the resources occupied by the first uplink control channel are overlapped with the resources occupied by the first uplink shared channel, and the first uplink control channel is associated with the first uplink shared channel. That is, when the uplink control information acquired by the network device comes from the first uplink control channel, only the information carried by the first uplink control channel is included; if the information is from the first uplink shared channel, the information may include UCI carried by the first uplink control channel and UCI carried by the first uplink shared channel after multiplexing the information carried by the first uplink control channel and the information carried by the first uplink shared channel.
In an alternative embodiment, the network device receives a first uplink control channel on a resource of the first uplink control channel; the network equipment receives a first uplink shared channel on the resource of the first uplink shared channel when the first uplink control channel is not received; the network equipment acquires part or all of information in first uplink control channel bearing information from the received first uplink shared channel, and acquires the information borne by the first uplink shared channel; the first uplink control channel is associated with the first uplink shared channel. It can be seen that the network device may detect the information carried by the first uplink control channel twice, that is, on the one hand, detect on the resources of the first uplink control channel, and if not, may detect part or all of the information carried by the first uplink control channel on the resources of the first uplink shared channel. Therefore, when the resources occupied by the plurality of uplink channels overlap, more uplink control information can be acquired as much as possible.
In another alternative embodiment, the network device receives a first uplink shared channel on a resource of the first uplink shared channel; the network equipment receives a first uplink control channel on the resource of the first uplink control channel when the first uplink shared channel is not received; the network equipment acquires part or all of information in the first uplink control channel bearing information from the received first uplink control channel; the first uplink control channel is associated with the first uplink shared channel. It can be seen that the network device may detect the uplink control information, that is, on the one hand, detect the uplink control information on the resources of the first uplink control channel, and if not, detect some or all of the information carried by the first uplink control channel on the resources of the first uplink shared channel. Therefore, when the resources occupied by the plurality of uplink channels overlap, more uplink control information can be acquired as much as possible.
It can be seen that the channels from which the uplink control information is obtained in the above two embodiments are different, and the uplink control information that can be obtained may also be different.
In an optional implementation manner, the HARQ-ACK included in the first uplink control channel bearer information is multiplexed with the information borne by the first uplink shared channel in a manner of punching on the resource occupied by the first uplink shared channel and is borne on the first uplink shared channel, where the number of bits of the HARQ-ACK included in the first uplink control channel bearer information is less than or equal to a second preset threshold; or, the HARQ-ACK included in the first uplink control channel bearer information is multiplexed with the information borne by the first uplink shared channel in a rate matching manner and is borne on the first uplink shared channel, where the number of bits of the HARQ-ACK included in the first uplink control channel bearer information is greater than the second preset threshold. As can be seen, this embodiment is beneficial for the network device to acquire the HARQ-ACK included in the first uplink control channel bearer information on the resources corresponding to the puncturing manner or on the resources corresponding to the rate matching manner.
In an optional implementation manner, the channel state information CSI included in the first uplink control channel bearer information is multiplexed with the information borne by the first uplink shared channel in a rate matching manner and is borne on the first uplink shared channel, where the information borne by the first uplink shared channel does not include CSI; or, the channel state information except the periodic channel state information P-CSI in the first uplink control channel bearer information is multiplexed with the information carried by the first uplink shared channel in a rate matching manner and is carried on the first uplink shared channel, where the information carried by the first uplink shared channel includes AP-CSI. As can be seen, this embodiment is beneficial for the network device to acquire, on the resources corresponding to the rate matching, the channel state information included in the first uplink control channel bearer information, or the channel state information included except the P-CSI.
In a seventh aspect, the present application further provides a channel transmission method, which is similar to the above sixth aspect, and is described from the perspective of the network device side, such as TRP1, where the resources occupied by the first uplink control channel overlap with the resources occupied by the first uplink shared channel, and the first uplink control channel is associated with the first uplink shared channel. The channel transmission method is different from the channel transmission method described in the sixth aspect in that the network device can detect the first uplink control channel once, and does not need to detect the information carried by the first uplink control channel twice, thereby being beneficial to reducing the processing burden of the network device, which will be described below.
In the channel transmission method, network equipment determines that a first uplink control channel is associated with a first uplink shared channel, and the resources occupied by the first uplink control channel overlap with the resources occupied by the first uplink shared channel; the network device receives one of the first uplink control channel and the first uplink shared channel.
In an optional implementation manner, the network device determines that a first uplink control channel is associated with the first uplink shared channel, where resources occupied by the first uplink control channel overlap with resources occupied by the first uplink shared channel; the network device receives one of the first uplink control channel and the first uplink shared channel.
For example, the network device receives a first uplink control channel and does not receive a first uplink shared channel, where a timing condition is not satisfied between the first uplink shared channel and the first uplink control channel; or the network equipment receives the first uplink shared channel, does not receive the first uplink shared channel, and acquires part or all of information in the first uplink control channel bearing information and information borne by the first uplink shared channel from the first uplink shared channel, wherein a time sequence condition is met between the first uplink shared channel and the first uplink control channel.
In an optional implementation manner, the HARQ-ACK included in the first uplink control channel bearer information is multiplexed with the information borne by the first uplink shared channel in a manner of punching on the resource occupied by the first uplink shared channel and is borne on the first uplink shared channel, where the number of bits of the HARQ-ACK included in the first uplink control channel bearer information is less than or equal to a second preset threshold; or, the HARQ-ACK included in the first uplink control channel bearer information is multiplexed with the information borne by the first uplink shared channel in a rate matching manner and is borne on the first uplink shared channel, where the number of bits of the HARQ-ACK included in the first uplink control channel bearer information is greater than the second preset threshold.
In an optional implementation manner, the channel state information CSI included in the first uplink control channel bearer information is multiplexed with the information borne by the first uplink shared channel in a rate matching manner and is borne on the first uplink shared channel, where the information borne by the first uplink shared channel does not include CSI; or, the channel state information except the periodic channel state information P-CSI in the first uplink control channel bearer information is multiplexed with the information carried by the first uplink shared channel in a rate matching manner and is carried on the first uplink shared channel, where the information carried by the first uplink shared channel includes the aperiodic channel state information AP-CSI.
The scene to which the embodiments of the present application are applicable may be an Ultra-Reliable and very Low-latency scene (URLLC) scene or an enhanced mobile broadband (Enhanced Mobile Broadband, eMBB) scene. In the URLLC scenario, only one uplink shared channel, for example, one PUSCH, is allowed to be transmitted in one time unit. In the ebb scenario, two uplink control channels and one uplink shared channel may be allowed in the same time unit, and both uplink control channels may carry HARQ-ACKs. The time unit may be a slot or a minislot mini-slot.
In yet another aspect, the channel transmission method may include: once the resources occupied by the multiple uplink channels overlap, the terminal may not transmit all the overlapped uplink channels, i.e., as long as there is a resource overlap occupied by the uplink channels, all the overlapped uplink channels are discarded.
In yet another aspect, the channel transmission method may include: the resources occupied by the plurality of uplink channels overlap, the uplink shared channel is preferentially sent, and the uplink control channel is discarded; or the uplink control channel is preferentially sent, and the uplink shared channel is discarded.
In still another aspect, the present application further provides a channel transmission method, where when resources occupied by a plurality of uplink channels overlap, the method described in the third aspect may be used to multiplex the associated uplink channels first; and secondly, determining which uplink channels are transmitted and which uplink channels are not transmitted according to the starting position and the occupied symbol length of each uplink channel aiming at the uplink channels after multiplexing, the associated uplink channels which cannot be multiplexed and the unassociated uplink channels.

Correspondingly, the network device side may perform the related operation described in the sixth aspect, further, may further determine an uplink channel sent by the terminal by combining the starting position of the uplink channel and the occupied symbol length, and receive the uplink channels on the resource of the sent uplink channel.

Detailed Description
The present application will present various aspects, embodiments, or features about a system that may include multiple devices, components, modules, etc. It is to be understood and appreciated that the various systems may include additional devices, components, modules, etc. and/or may not include all of the devices, components, modules etc. discussed in connection with the figures. Furthermore, combinations of these schemes may also be used.
In addition, in the embodiments of the present application, the term "exemplary" is used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, the term use of an example is intended to present concepts in a concrete fashion.
In the embodiment of the present application, information, signals, messages, channels may be mixed in some cases, and it should be noted that, when the distinction is not emphasized, the meaning to be expressed is consistent. "of", "corresponding" and "corresponding" are sometimes used in combination, and it should be noted that the meaning of the expression is consistent when the distinction is not emphasized.
The technical scheme of the application can be particularly applied to various communication systems, such as: global system for mobile communications (Global system for mobile communications, abbreviated as GSM), code Division multiple access (Code Division Multiple Access, abbreviated as CDMA), wideband code Division multiple access (Wideband Code Division Multiple Access, abbreviated as WCDMA), time Division synchronous code Division multiple access (Time Division-Synchronous Code Division Multiple Access, abbreviated as TD-SCDMA), universal mobile telecommunications system (Universal Mobile Telecommunications System, abbreviated as UMTS), long term evolution (Long Term Evolution, abbreviated as LTE) system, etc., with the development of communication technology, the technical solution of the present application may also be used in future networks, such as 5G system, also referred to as New Radio (abbreviated as NR) system, or may be used in device-to-device (abbreviated as D3D) system, machine-to-machine (machine to machine, abbreviated as M2M) system, etc.
The technical scheme of the application can also be applied to the Internet of vehicles, that is, the terminal can also be a vehicle or a vehicle component applied to the vehicle. Among them, under the LTE system proposed by the third generation partnership project (the 3rd generation partnership project,3GPP), the internet of vehicles (vehicle to everything, V2X) technology (X stands for anything) in which vehicles communicate with anything is proposed. The communication modes in the V2X system are collectively referred to as V2X communication. For example, the V2X communication includes: communication between a vehicle and a vehicle (vehicle to vehicle, V2V), communication between a vehicle and roadside infrastructure (vehicle to infrastructure, V2I), communication between a vehicle and a pedestrian (vehicle to pedestrian, V2P), or communication between a vehicle and a network (vehicle to network, V2N), and the like. The communication between the terminal devices involved in the V2X system is widely referred to as a Side Link (SL) communication.
Currently, vehicles or vehicle components can timely acquire road condition information or receive service information through a V2V, V2I, V P or V2N communication mode, and the communication modes can be collectively called V2X communication. Fig. 1 is a schematic diagram of a V2X system of the prior art. The schematic includes V2V communication, V2P communication, and V2I/N communication. V2X communication is a basic technology and a key technology applied to high-speed equipment represented by vehicles in the scene with very high requirements on communication delay in the future, such as intelligent automobiles, automatic driving, intelligent transportation systems and the like.
As shown in fig. 1, vehicles or vehicle components communicate with each other via V2V. The vehicle or the vehicle component can broadcast the information such as the vehicle speed, the running direction, the specific position, whether the emergency brake is stepped on or not and the like to surrounding vehicles, and the driver of the surrounding vehicles can better sense the traffic condition outside the sight distance by acquiring the information, so that the dangerous condition is pre-judged in advance and avoided; the vehicle or vehicle component communicates with the roadside infrastructure via V2I, and the roadside infrastructure may provide the vehicle or vehicle component with access to various service information and data networks. Wherein, functions such as no-stop charge, in-car entertainment and the like greatly improve traffic intellectualization. Roadside infrastructure, for example, road Side Units (RSUs), include two types: one is an RSU of the terminal equipment type. Because the RSUs are distributed at the roadsides, the RSUs of the terminal equipment type are in a non-moving state, and mobility does not need to be considered; another is an RSU of the network device type. The RSU of the network device type may provide timing synchronization and resource scheduling for vehicles or vehicle components in communication with the network device. The vehicle or vehicle component communicates with the person through V2P; the vehicle or vehicle component communicates with the network via V2N, which may be collectively referred to as V2I/N with V2I described above.
The network architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided in the embodiments of the present application, and as a person of ordinary skill in the art can know, with evolution of the network architecture and appearance of a new service scenario, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.
In the embodiment of the present application, a part of the scenes are described by taking a scene of an NR network in a wireless communication network as an example, and it should be noted that the solution in the embodiment of the present application may also be applied to other wireless communication networks, and the corresponding names may also be replaced by names of corresponding functions in other wireless communication networks.
The network device in the present application may be a device with a wireless transceiver function or a chip that may be disposed on the device, where the network device includes, but is not limited to: an evolved Node B (eNB), a radio network controller (radio network controller, RNC), a Node B (Node B, NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a home base station (home evolved NodeB, or home Node B, HNB), a Base Band Unit (BBU), an Access Point (AP) in a wireless fidelity (wireless fidelity, WIFI) system, a wireless relay Node, a wireless backhaul Node, a transmission point (transmission and reception point, TRP or transmission point, TP), etc., may also be 5G, such as NR, a gbb in a system, or a transmission point (TRP or TP), one or a group (including multiple antenna panels) of antenna panels of a base station in a 5G system, or may also be a network Node constituting a gbb or a transmission point, such as a baseband unit (BBU), or a distributed unit (DU, distributed unit), etc., a network device or a network RSU type of a network device in a V2X vehicle as described above.
In some deployments, the gNB or transmission point may include a Centralized Unit (CU) and DUs. The gNB may also include a Radio Unit (RU). The CU implements part of the functions of the gNB or the transmission point, the DU implements part of the functions of the gNB or the transmission point, for example, the CU implements the functions of a radio resource control (radio resource control, RRC), a packet data convergence layer protocol (packet data convergence protocol, PDCP) layer, and the DU implements the functions of a radio link control (radio link control, RLC), a medium access control (media access control, MAC), and a Physical (PHY) layer. Since the information of the RRC layer may be eventually changed into the information of the PHY layer or converted from the information of the PHY layer, under this architecture, higher layer signaling, such as RRC layer signaling or PHCP layer signaling, may also be considered as being transmitted by the DU or by the du+ru. It is understood that the network device may be a CU node, or a DU node, or a device comprising a CU node and a DU node. In addition, the CU may be divided into network devices in the access network RAN, or may be divided into network devices in the core network CN, which is not limited herein.
A terminal in this application may also be referred to as a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. The terminal device in the embodiments of the present application may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), a wireless terminal in the aforementioned V2X car networking or RSU of a wireless terminal type, or the like. The embodiments of the present application are not limited to application scenarios.
To facilitate an understanding of the embodiments of the present application, a communication system illustrated in fig. 2 is illustrated as an example. Referring to fig. 2, fig. 2 is a schematic diagram of a multi-transmission receiving point TRP cooperative transmission provided in the embodiment of the present application, and fig. 2 is an example where both network devices TRP1 and TRP2 are capable of communicating with a terminal.
With the rapid development of mobile communication, the coordinated multi-point transmission technology can improve system performance, especially improve the spectrum efficiency at the cell edge. As shown in fig. 2, the terminal may determine a physical uplink control channel (Physical Uplink Control Channel, PUCCH) 1 and a physical uplink shared channel (Physical Uplink Share Channel, PUSCH) 1 corresponding to TRP1, and PUCCH2 corresponding to TRP 2; further, the terminal needs to transmit a physical uplink control channel (Physical Uplink Control Channel, PUCCH) 1 and a physical uplink shared channel (Physical Uplink Share Channel, PUSCH) 1 to TRP1, respectively; PUCCH2 is transmitted to TRP 2. Once the resources occupied by the multiple uplink channels overlap, as the PUSCH1 overlaps with the PUCCH1 and the PUCCH2, how the terminal transmits the uplink channels, so as to facilitate the network device to obtain the uplink control information carried by the uplink channels sent by the terminal, is a problem to be solved.
Therefore, in order to solve the above-mentioned problem, the present application provides a channel transmission method, which can transmit at least one uplink channel of a plurality of uplink channels when resources occupied by the plurality of uplink channels overlap, so as to be beneficial for a network device to obtain uplink control information carried by the uplink channel sent by a terminal.
To facilitate an understanding of the embodiments of the present application, several related concepts will first be briefly described.
In this embodiment of the present application, the overlapping of resources occupied by the plurality of uplink channels may include overlapping on time domain resources, frequency domain resources, or time-frequency domain resources.
The time domain resource may refer to a subframe, a slot (slot), a radio frame, a minislot (mini slot or subslot), a plurality of aggregated slots, a plurality of aggregated subframes, symbols, and the like, and may refer to a transmission time interval (Transmission Time Interval, TTI). One or more time units may be included in the time domain, where one time unit may include an integer number of another time unit, or a duration of one time unit in the time domain is equal to a duration of an integer number of another time unit in the time domain, for example, one minislot/slot/subframe/radio frame includes an integer number of symbols, one slot/subframe/radio frame includes an integer number of minislots, one subframe/radio frame includes an integer number of slots, one radio frame includes an integer number of subframes, and the like, or other including examples may exist, which are not limited in this application.
The frequency domain resources include subcarriers, resource Blocks (RBs), physical resource blocks, virtual resource blocks, precoding resource block groups (precoding resource block group, PRG), physical resource block groups (physical resource block group, RBG), subbands (subband), partial bandwidths (partial bandwidth), bandwidth parts (BWP), carriers (carriers), serving cells (serving cells), frequency bands (bands), and the like.
The time-frequency resource comprises a frequency domain resource corresponding to a certain time domain resource.
In this embodiment, the overlapping of the resources occupied by the plurality of uplink channels may be in a section of time domain unit (also called time unit), a section of frequency domain unit, or a section of time-frequency unit, where the resources occupied by the plurality of uplink channels are partially overlapped or fully overlapped. For example, the overlapping of the resources occupied by the plurality of uplink channels may be that the resources occupied by the plurality of uplink channels overlap on one slot or one symbol; or, on one subcarrier or resource block, the resources occupied by a plurality of uplink channels overlap. Accordingly, the present application describes a channel transmission method of a terminal or a network device by taking overlapping resources occupied by at least two uplink channels in a first uplink control channel, a second uplink control channel, and a first uplink shared channel as an example, and "first" and "second" in the present application do not refer to numbers or sequences.
In this embodiment of the present application, the overlapping of resources occupied by a plurality of uplink channels may also be referred to as overlapping of resources occupied by a plurality of uplink channels, or a plurality of uplink channel conflicts, or a plurality of uplink channel transmission conflicts, or the like, which is not limited by the embodiment of the present application.
In this embodiment of the present application, the uplink channel may be a generic term of an uplink control channel and an uplink shared channel, that is, the uplink channel may be an uplink control channel or an uplink shared channel unless otherwise specified. Wherein, the uplink control channels may include physical uplink control channel (Physical Uplink Control Channel, PUCCH), enhanced physical uplink control channel EPUCCH (Enhanced Physical Uplink Control Channel, EPUCCH); the uplink shared channel may include a physical uplink shared channel (Physical Uplink Share Channel, PUSCH).
The "associated uplink channel" set forth in the embodiments of the present application may be the resources occupied by the associated uplink control channel and the resources occupied by the uplink shared channel; the non-associated uplink channels may be the resources occupied by the non-associated uplink control channels and the resources occupied by the uplink shared channels. The uplink control channel is associated with the uplink shared channel, which means that the uplink control channel and the uplink shared channel are sent to the same network device; correspondingly, the resources occupied by the uplink control channel and the resources occupied by the uplink shared channel are not associated, which means that the uplink control channel and the uplink shared channel are respectively sent to different network devices.
In the embodiment of the present application, whether the resources occupied by the uplink control channel and the resources occupied by the uplink shared channel are associated may be determined by whether the downlink control related parameters respectively corresponding to the channels are the same.
In an alternative embodiment, if the uplink control channel includes a hybrid automatic repeat request (Hybrid Automatic Repeat request, HARQ) -acknowledgement information (ACK), the downlink control related parameter corresponding to the uplink control channel is a downlink control related parameter of DCI for scheduling a data channel corresponding to the HARQ-ACK, such as a physical downlink shared channel (Physical Downlink Share Channel, PDSCH); the downlink control parameter corresponding to the uplink shared channel is a downlink control related parameter of DCI for scheduling the uplink shared channel, so that whether the resources occupied by the uplink control channel are related to the resources occupied by the uplink shared channel can be determined according to whether the two downlink control related parameters are the same. For example, if the HARQ-ACK carried by the PUCCH is fed back for data carried by the PDSCH, the downlink control related parameter corresponding to the PUCCH is a downlink control related parameter of DCI1 for scheduling the PDSCH; accordingly, the downlink control related parameter corresponding to PUSCH is the downlink control related parameter of DCI2 for scheduling the PUSCH, and therefore, when the downlink control related parameter of the DCI1 is the same as the downlink control related parameter of DCI2, the PUCCH is associated with PUSCH.
In another optional implementation manner, if the uplink control channel does not include HARQ-ACK, the downlink control related parameter corresponding to the uplink control channel is a downlink control related parameter carried in configuration information of channel state information carried by the uplink control channel; thus, whether the uplink control channel is associated with the uplink shared channel may be determined based on whether the downlink control related parameter is the same as the downlink control related parameter in the DCI scheduling the uplink shared channel. For example, if the PUCCH does not include HARQ-ACK but includes channel state information, the downlink control related parameter corresponding to the PUCCH is a downlink control related parameter carried in configuration information of the channel state information; correspondingly, when the downlink control related parameter carried in the configuration information of the channel state information is the same as the downlink control related parameter in DCI2 for scheduling PUSCH, the PUCCH is associated with the PUSCH.
The downlink control related parameters may include a physical downlink control channel configuration parameter (Physical Downlink Control Channel Config, PDCCH-Config), a control resource set configuration parameter (Control Resource Sets, core) or a control resource set configuration parameter set (Control Resource Sets group, core group), and so on. The PDCCH-Config includes parameters for detecting candidate downlink control channels (Physical Downlink Control Channel, PDCCH). CORESET may be referred to as a control resource set, i.e., a time-frequency resource of CORESET, such as a resource block size occupied by a frequency domain, a number of symbols occupied by a time domain, etc.; CORESET refers to relevant parameters of signaling configuration for obtaining CORESET time-frequency resources. The CORESET group may include one or more control resource set configuration parameters or index numbers of control resource set configuration parameters, wherein one control resource set configuration parameter may be represented by an index number or an identification. When a CORESET group contains a CORESET, the CORESET group identifier may be used as a CORESET identifier, or a CORESET identifier may be used as a CORESET group identifier. Other downlink control channel configuration parameters are similar.
In the embodiment of the present application, the harq acknowledgement information is used to perform positive (ACK) or Negative (NACK) feedback on received data, such as data carried by PDSCH, so that lost or erroneous data can be quickly retransmitted. In the embodiment of the present application, the illustrated HARQ-ACK is not a single-finger positive feedback, but rather refers to all feedback of data carried by the corresponding PDSCH. For ease of description herein, the hybrid automatic repeat request acknowledgement information will be simply described as HARQ-ACK.
In this embodiment, for association between an uplink control channel and an uplink shared channel, if information carried on the uplink control channel needs to be multiplexed with information carried on the uplink shared channel and carried on the uplink shared channel, a certain time delay needs to be met between the uplink shared channel and the uplink control channel, or a time sequence condition needs to be met between the uplink control channel and the uplink shared channel. The timing condition may also be referred to as a latency relationship or a multiplexing timing condition, i.e. the terminal needs to have the ability to report its own prepared downlink shared channel. That is, data information, CSI information, multiplexed information, and the like carried by the downlink shared channel need to be considered. For example, when transmitting the uplink shared channel, the processing delay of the downlink shared channel and the demodulation parameter signals (Demodulation Reference Signal, DMRS) corresponding to the downlink shared channel needs to be considered according to the capability of the terminal; when aperiodic CSI exists, the processing time delay of the CSI also needs to be considered; and the processing delay of the uplink shared channel and the corresponding DMRS thereof and the like need to be considered according to the capability of the terminal. Therefore, if part or all of the information carried by the uplink control channel is multiplexed with the information carried by the uplink shared channel and carried on the uplink shared channel to be transmitted, the uplink shared channel needs to meet the above processing delay.
In this embodiment of the present application, the "multiplexing" has two cases, where the first multiplexing refers to that, for an uplink control channel and an uplink shared channel are associated and resources occupied by the uplink control channel overlap with resources occupied by the uplink shared channel, information carried by the uplink control channel is multiplexed with information carried by the uplink shared channel, and carried on the uplink shared channel for transmission; the second multiplexing means that, for the uplink control channel and the uplink shared channel that are not associated and the resources occupied by the uplink control channel overlap with the resources occupied by the uplink shared channel, holes are punched in the positions of the resources occupied by the uplink shared channel and the resources occupied by the uplink control channel, so as to transmit the uplink control channel and the uplink shared channel simultaneously.
Multiplexing part or all of the information carried by the uplink control channel with the information carried by the uplink shared channel in a punching mode, and obtaining the data which is punched and not transmitted in an error correction mode when the network equipment receives the uplink shared channel. Likewise, for puncturing in the second case, the network device may also obtain data that is not transmitted due to the puncturing of the resources by error correction.
In the multiplexing of the above two cases, "puncturing" means that, on the terminal side, a part of the resources occupied by the uplink shared channel are removed, and at the same time, the data that should be placed by the part of the resources are skipped or not transmitted, but on the network device side, it is considered that the resources occupied by the uplink shared channel are not lost, so that the skipped or not transmitted data can be obtained by error correction.
The "puncturing" in the multiplexing of the above two cases is different in that, in the first case, the position to be punctured is not necessarily the resource position where the resources occupied by the two uplink channels overlap, and in the second case, the position to be punctured is necessarily the resource position where the resources occupied by the two uplink channels overlap. In addition, the rate matching in the first case of multiplexing means that, on the terminal side, a part of the resources occupied by the uplink shared channel are removed, and at the same time, the data that should be placed by the part of the resources are skipped or not transmitted, and on the network device side, it is known that the part of the resources occupied by the uplink shared channel are missing.
In an alternative embodiment, for the precondition of "multiplexing" in the second case, whether the resources occupied by the uplink control channel overlap with the resources occupied by the DMRS corresponding to the uplink shared channel, and the total number of bits of the uplink control channel bearer information are included. Because the multiplexing in this case is to puncture the resources overlapping with the resources occupied by the uplink control channel in the resources occupied by the uplink shared channel, the DMRS may be missing or the network side may not receive the DMRS, which affects the channel estimation, and further may not be successfully received by the entire uplink shared channel. Therefore, when the resources occupied by the uplink control channel and the resources occupied by the DMRS corresponding to the uplink shared channel do not overlap, and the total number of bits of the uplink control channel bearer information is smaller than the first preset threshold, the uplink shared channel and the uplink control channel are necessarily transmitted in the multiplexing mode.
In another alternative embodiment, for the precondition of "multiplexing" in the second case, it may also be considered whether the transmission power of the resource overlapped between the resource occupied by the uplink control channel and the resource occupied by the uplink shared channel exceeds the maximum transmission power, and if the transmission power exceeds the maximum transmission power, the "multiplexing" is not considered any more, and only one channel is selected for transmission; if the maximum transmission power is not exceeded, the precondition in the above embodiment may be further considered, that is, whether the resources occupied by the uplink control channel overlap with the resources occupied by the DMRS corresponding to the uplink shared channel. Therefore, the problem that the transmission power is too small after the uplink shared channel is punched, so that the uplink shared channel cannot be received is avoided.
In the embodiment of the present application, the information carried by the uplink control channel may be referred to as uplink control information (Uplink Control Information, UCI), and the UCI carried by the uplink control channel may include one or more of HARQ-ACK and channel state information. The channel state information carried by the uplink control channel may include periodic channel state information (P-CSI), semi-static channel state information (semi-CSI), etc. The information carried by the uplink shared channel may include one or more of UCI and data information. The UCI carried on the uplink shared channel may include semi-static channel state information (semi-CSI) and aperiodic channel state information (AP-CSI). The semi-static channel state information (semi-CSI) is configured on which channel of the uplink control channel and the uplink shared channel is transmitted, and UCI information carried by which channel may include the semi-CSI. The information carried by the uplink control channel is multiplexed with the information carried by the associated uplink shared channel, and the UCI carried by the uplink shared channel may further include HARQ-ACK when the information carried by the uplink control channel is transmitted on the uplink shared channel. In summary, the information or UCI carried by the uplink control channel may include HARQ-UCI; the information carried by the uplink shared channel may include UCI and data information, wherein the UCI may include channel state information, and when the information carried by the uplink control channel is multiplexed with and carried on the information carried by the uplink shared channel, the UCI carried by the uplink shared channel may further include HARQ-ACK.
In an alternative embodiment, the priority of the HARQ-ACK is higher than the priority of the channel state information, so that the HARQ-ACK can be fed back to the network device as soon as possible. In another alternative embodiment, the priority of the HARQ-ACK may be lower than the priority of the channel state information, so that the channel state information can be fed back to the network device as soon as possible. Thus, embodiments of the present application do not limit the priority of both, and may be specifically predefined or configured in conjunction with an application scenario.
In an alternative embodiment, the priority among the AP-CSI, the P-CSI, the semi-CSI carried on the uplink shared channel, and the semi-CSI carried on the uplink control channel may be: the priority of the AP-CSI is higher than the priority of semi-CSI carried on an uplink shared channel; "priority of semi-CSI carried on uplink shared channel" is higher than "priority of semi-CSI carried on uplink control channel"; the "priority of semi-CSI carried on uplink control channel" is higher than the "priority of P-CSI". In another alternative embodiment, the priority of each channel state information may be predefined or configured correspondingly according to the application scenario. The embodiments of the present application are not limited.
In the embodiment of the present application, the priority of the information carried by the uplink shared channel is determined by the priority with the highest priority in the information carried by the uplink shared channel; the priority of the information carried by the uplink control channel is determined by the highest priority among the information carried by the uplink control channel. For example, if the priority of HARQ-ACK is higher than the priority of channel state information, the priority of uplink shared channel bearer information is determined by whether the uplink shared channel carries hybrid automatic repeat request acknowledgement information HARQ-ACK, and if HARQ-ACK is carried, the priority of uplink shared channel bearer information is the highest; if the HARQ-ACK is not carried, the priority of the uplink shared channel carrying information is relatively low; the priority of the uplink control channel bearing information is determined by whether the uplink control channel bears the HARQ-ACK (hybrid automatic repeat request acknowledgement) information, and if the uplink control channel bears the HARQ-ACK, the priority of the uplink control channel bearing information is highest; if the HARQ-ACK is not carried, the priority of the uplink control channel carrying information is relatively low.
Based on the related description, the channel transmission method of the present application can transmit at least one uplink channel when the resources occupied by a plurality of uplink channels overlap in a multi-point transmission scene, so that the corresponding network device can timely obtain the information carried by the transmitted uplink channel. In addition, in each embodiment, there are two uplink control channels that may carry HARQ-ACKs, a second uplink control channel, and one uplink shared channel in one time unit, where the uplink control channel is associated with the uplink shared channel, the second uplink control channel is not associated with the other two channels, and resources occupied by the uplink control channel and resources occupied by the uplink shared channel are needed to be sent to TRP1, and the second uplink control channel is needed to be sent to TRP2, which is described in connection with the communication system shown in fig. 2.
As shown in fig. 3a, when the terminal device determines that the resources occupied by the first uplink control channel, the resources occupied by the second uplink control channel, and the resources occupied by the first uplink shared channel do not overlap each other in one time unit, the terminal sends the three uplink channels respectively, and accordingly, TRP1 can receive the first uplink control channel and the first uplink shared channel, and TRP2 can receive the second uplink control channel.
As shown in fig. 3b, the resources occupied by the first uplink control channel overlap with the resources occupied by the first uplink shared channel, and the resources occupied by the second uplink control channel do not overlap with the resources occupied by the other two uplink channels; as shown in fig. 3c, the resources occupied by the first uplink shared channel overlap with the resources occupied by the second uplink control channel, and the resources occupied by the first uplink control channel do not overlap with the resources occupied by the other two uplink channels; as shown in fig. 3d, the resources occupied by the first uplink shared channel overlap with the resources occupied by the first uplink control channel and the resources occupied by the second uplink control channel; as shown in fig. 3e, the resources occupied by the first uplink shared channel overlap with the resources occupied by the first uplink control channel and the resources occupied by the second uplink control channel. The channel transmission method is explained below with respect to the overlap shown in fig. 3b to 3e in such a way that the terminal interacts with TRP1, TRP 2. When the resources occupied by the plurality of uplink channels overlap, the uplink channel that is not transmitted by the terminal may also be referred to as a terminal discarding the uplink channel (i.e., drop uplink channel).
1. Channel transmission method when resource occupied by associated uplink control channel and resource occupied by uplink shared channel overlap
In this embodiment, when the resources occupied by the associated uplink control channel overlap with the resources occupied by the uplink shared channel, the terminal transmits one of the uplink shared channel and the uplink control channel.
In an optional implementation manner, the terminal multiplexes information carried by an uplink control channel with information carried by the uplink shared channel and carries the multiplexed information on the uplink shared channel, and further, the terminal may send the uplink shared channel and not send the uplink control channel. The embodiment may be performed in such a manner that a timing condition is satisfied between the uplink control channel and the uplink shared channel. In particular, how to determine whether the timing condition is satisfied may be determined in conjunction with the related concepts described above, and will not be described in detail herein.
In another optional implementation manner, the terminal does not send the uplink shared channel, and sends the uplink control channel. The embodiment may be executed when a timing condition is not satisfied between the uplink control channel and the uplink shared channel.
The terminal multiplexes the information carried by the uplink control channel with the information carried by the uplink shared channel, which may be multiplexed in a puncturing or rate matching manner.
In an example, the terminal multiplexes HARQ-ACK included in uplink control channel bearer information with information carried by the uplink shared channel by punching on a resource of the uplink shared channel; the number of bits of HARQ-ACK included in the uplink control channel bearer information is less than or equal to a second preset threshold, and the multiplexing manner described in this example may be executed. In another example, the terminal multiplexes HARQ-ACK included in the uplink control bearer information with information carried by the uplink shared channel in a rate matching manner; when the number of bits of HARQ-ACK included in the uplink control bearer information is greater than the second preset threshold, the multiplexing manner described in this example may be executed.
In yet another example, the terminal multiplexes channel state information contained in the uplink control channel bearer information with information carried by the uplink shared channel in a rate matching manner; the information carried by the uplink shared channel does not include channel state information, and the exemplary manner may be executed.
In another example, when the uplink control channel includes channel state information, the uplink shared channel also includes channel state information, and the terminal may discard CSI information included in the uplink control channel, that is, in this case, the channel state information carried by the uplink control channel is not multiplexed. In yet another example, the terminal multiplexes channel state information included in the uplink control channel bearer information except for periodic channel state information P-CSI with information carried by the uplink shared channel in a rate matching manner; the information carried by the uplink shared channel includes channel state information, and the exemplary manner may be executed.
The first preset threshold may be a preset number of bits of HARQ-ACK. The first preset threshold may be 2bits or 4bits, etc. The first preset threshold may be configured according to requirements.
For example, when the information carried by the uplink control channel includes HARQ-ACK and P-CSI, and there is no AP-CSI in the uplink shared channel, the HARQ-ACK and P-CSI may be multiplexed with the information carried by the uplink shared channel and transmitted on the uplink shared channel. For another example, when the uplink control information includes HARQ-ACK and P-CSI, and the uplink shared channel includes AP-CSI, the terminal may discard the P-CSI, multiplex the HARQ-ACK with information carried by the uplink shared channel, and transmit the multiplexed information on the uplink shared channel.
For the network device side, the associated uplink control channel and uplink shared channel can be sent to the same network device. In an alternative embodiment, the network device receives the uplink control channel on the resource of the uplink control channel; the network equipment receives the uplink shared channel on the resources of the uplink shared channel when the uplink control channel is not received; the network equipment acquires part or all of the uplink control channel bearing information from the received uplink shared channel, and acquires the information borne by the uplink shared channel; the uplink control channel is associated with the uplink shared channel. It can be seen that the network device may detect the information carried by the uplink control channel twice, that is, detect the information carried by the uplink control channel on the resources of the uplink control channel, and if not, detect some or all of the information carried by the uplink control channel on the resources of the uplink shared channel. Thus, this embodiment is advantageous in that more uplink control information is obtained by direct detection when the resources occupied by the plurality of uplink channels overlap. Accordingly, how the network device detects part or all of the information carried by the uplink control channel from the uplink shared channel can be determined by referring to the relevant content multiplexed herein.
In another optional implementation manner, the network device can learn that the resources occupied by the uplink control channel overlap with the resources occupied by the uplink shared channel, and the network device determines that the uplink control channel is associated with the uplink shared channel, where the resources occupied by the uplink control channel overlap with the resources occupied by the uplink shared channel; and the network equipment receives one of the uplink control channel and the uplink shared channel. For example, the timing condition is satisfied between the uplink shared channel and the uplink control channel, and the network device receives the uplink shared channel and does not receive the uplink control channel. For another example, the timing condition is not satisfied between the uplink shared channel and the uplink control channel, and the network device does not receive the uplink shared channel and receives the uplink control channel. In this embodiment, the network device can detect the uplink control channel once, and does not need to detect the information carried by the uplink control channel twice, thereby being beneficial to reducing the processing burden of the network device. Accordingly, how the network device detects part or all of the information carried by the uplink control channel from the uplink shared channel can be determined by referring to the relevant content multiplexed herein.
As shown in fig. 3b, the resources occupied by the first uplink control channel overlap with the resources occupied by the first uplink shared channel, and the resources occupied by the second uplink control channel do not overlap with the resources occupied by the other uplink channels, so that the terminal can transmit the second uplink control channel, and TRP2 can receive the second uplink control channel. Referring to fig. 4, for a first uplink control channel and a first uplink shared channel, the channel transmission method may include the steps of:
101. the terminal determines that the resources occupied by a first uplink control channel overlap with the resources occupied by a first uplink shared channel, wherein the first uplink shared channel is associated with the first uplink control channel;
specifically, whether the resources occupied by the first uplink control channel overlap with the resources occupied by the first uplink shared channel or whether the first uplink shared channel is associated with the first uplink control channel is determined by referring to the relevant content of "overlapping" or "associating" herein, which will not be described in detail herein.
102. The terminal judges whether the first uplink control channel and the first uplink shared channel meet the time sequence condition, if yes, the step 103 is executed; if the timing condition is not satisfied, executing step 104;
103. Multiplexing part or all of information borne by an uplink control channel with information borne by an uplink shared channel in a punching or rate matching mode by a terminal, bearing the information on a first uplink shared channel, transmitting the first uplink shared channel, and not transmitting the first uplink control channel; TRP1 may receive the first uplink shared channel and acquire part or all of the information carried by the first uplink control channel and the information carried by the first uplink shared channel from the first uplink shared channel.
104. The terminal sends a first uplink control channel and does not send a first uplink shared channel; TRP1 receives the first uplink control channel and does not receive the first uplink shared channel.
As can be seen, when the first uplink control channel and the first uplink shared channel meet the time sequence condition, the channel transmission method can multiplex part or all of the information carried by the first uplink control channel, namely UCI information, onto the first uplink shared channel in time in a multiplexing manner to send, thereby being beneficial to TRP1 to acquire UCI information in time; even if the two do not meet the time sequence condition, the first uplink control channel can be sent preferentially, so that TRP1 can acquire UCI information carried by the first uplink control channel in time.
2. Channel transmission method when resources occupied by non-associated uplink control channel overlap with resources occupied by uplink shared channel
In this embodiment, the resources occupied by the uplink control channel overlap with the resources occupied by the uplink shared channel, and the uplink control channel is not associated with the uplink shared channel, and the terminal transmits at least one of the uplink shared channel and the uplink control channel.
In an optional implementation manner, when the precondition of the second situation of multiplexing is satisfied and the total bit number of the uplink control channel bearer information is less than or equal to the first preset threshold, holes may be drilled on the resources occupied by the uplink shared channel, where the resources occupied by the uplink shared channel overlap with the resources occupied by the uplink control channel, and the uplink control channel and the uplink shared channel are sent; and when the precondition of multiplexing in the second condition is not satisfied or the total bit number of the uplink control channel bearing information is larger than a first preset threshold value, the terminal sends one of the uplink shared channel and the uplink control channel. Accordingly, since the resources occupied by the uplink control channel and the resources occupied by the uplink shared channel which are not associated are respectively transmitted to different network devices, each network device can only receive its own uplink control channel and uplink shared channel, and if not, it indicates that the reception has failed.
The first preset threshold may be a preset total number of bits of the uplink control channel bearer information. The first preset threshold may be 2bits or 4bits, etc.
In an alternative embodiment, the terminal transmits one of the uplink shared channel and the uplink control channel. In an optional implementation manner, the terminal does not send the uplink shared channel and sends the uplink control channel; or the terminal sends the uplink shared channel and does not send the uplink control channel. The information borne by the uplink control channel comprises hybrid automatic repeat request acknowledgement information (HARQ-ACK), and the terminal does not send the uplink shared channel and sends the uplink control channel; and the information carried by the uplink control channel does not contain HARQ-ACK, and the terminal sends the uplink shared channel and does not send the uplink control channel. It can be seen that, in this embodiment, on one hand, the terminal is facilitated to preferentially send HARQ-ACK to the network device, and on the other hand, the terminal is facilitated to preferentially send UCI information and/or data carried by the uplink shared channel to the network device.
For example, as shown in fig. 3c, the resources occupied by the first uplink shared channel overlap with the resources occupied by the second uplink control channel, and the resources occupied by the first uplink control channel do not overlap with the resources occupied by the other uplink channels, so the terminal may directly transmit the first uplink control channel. Referring to fig. 5, for the first uplink shared channel and the second uplink control channel, the channel transmission method may include the following steps:
201. The terminal determines that the resources occupied by the first uplink shared channel overlap with the resources occupied by the second uplink control channel, and the second uplink control channel is not associated with the first uplink shared channel;
202. the terminal judges whether the resources occupied by the uplink control channel and the resources occupied by the DMRS corresponding to the uplink shared channel are overlapped or not, and whether the total bit number of the uplink control channel bearing information is smaller than or equal to a first preset threshold value or not; if the resources occupied by the uplink control channel and the resources occupied by the DMRS corresponding to the uplink shared channel do not overlap, and the total number of bits of the second uplink control channel bearer information is less than or equal to the first preset threshold, executing step 203; if the resources occupied by the uplink control channel overlap with the resources occupied by the DMRS corresponding to the uplink shared channel, or the total number of bits of the uplink control channel bearer information is greater than the first preset threshold, executing step 204;
203. the terminal adopts a mode of punching holes on the resources occupied by the first uplink shared channel to send the first uplink shared channel and the second uplink control channel; TRP1 receives the first uplink shared channel and TRP2 receives the second uplink control channel;
204. the terminal judges whether the information borne by the second uplink control channel contains HARQ-ACK; if so, go to step 205; if not, go to step 206;
205. The terminal does not send the first uplink shared channel and sends a second uplink control channel; TRP1 cannot receive the first uplink shared channel; TRP2 receives a second uplink control channel;
206. the terminal does not send the second uplink control channel and sends a first uplink shared channel; TRP1 first uplink shared channel, TRP2 cannot receive the second uplink control channel.
In this embodiment, when the resources occupied by the uplink shared channel and the resources occupied by the uplink control channel overlap, and the second condition is satisfied, and the total number of bits of the uplink control channel bearer information is less than or equal to the first preset threshold, the uplink shared channel and the uplink control channel may be sent respectively; when the second condition is not satisfied, multiplexing or the total bit number of the uplink control channel bearing information is greater than a first preset threshold, if the uplink control channel contains HARQ-ACK, the uplink control channel can be sent, and the uplink shared channel is not sent; thus, the HARQ-ACK is transmitted to the network equipment in time. Correspondingly, if the uplink control channel does not contain HARQ-ACK, the uplink shared channel can be sent, and the uplink control channel is not sent; thus, the data and/or channel state information carried by the uplink shared channel are advantageously transmitted to the network device.
3. Channel transmission method when resources occupied by associated uplink channels overlap and resources occupied by non-associated uplink channels also overlap
In the present application, when the resources occupied by the associated uplink channels overlap, and the resources occupied by the non-associated uplink channels also overlap, the terminal may combine the embodiments in the case of overlapping the two cases 1 and 2, and finally determine which uplink channel is transmitted, which uplink channel is not transmitted, or transmit all the uplink channels.
In an alternative embodiment, the terminal may determine the transmission mode of the associated uplink channel by using the embodiment described in 1 above for the associated uplink channel, and then further determine the transmission mode of the non-associated uplink channel by combining the embodiment described in 2 above.
For example, the resources occupied by the first uplink shared channel overlap with the resources occupied by the first uplink control channel and the resources occupied by the second uplink control channel, and when the terminal determines to transmit the first uplink control channel according to the embodiment described in the above 1 and does not transmit the first uplink shared channel, the terminal may directly perform the second uplink control channel without performing the operation in the embodiment described in the above 2; when the terminal determines not to transmit the first uplink control channel according to the embodiment described in the above 1 and transmits the first uplink shared channel, the terminal also needs to transmit at least one of the first uplink shared channel and the second uplink control channel in combination with the steps described in the embodiment described in the above 2.
In the channel transmission method as described in the above 2, resources occupied by the second uplink control channel and resources occupied by demodulation reference signals (Demodulation Reference Signal, DMRS) corresponding to the first uplink shared channel do not overlap, and the total number of bits of the second uplink control channel bearer information is less than or equal to a first preset threshold, and the terminal uses a manner of puncturing the resources occupied by the first uplink shared channel to transmit the first uplink shared channel and the second uplink control channel. And the resources occupied by the second uplink control channel are overlapped with the resources occupied by the demodulation reference signals corresponding to the first uplink shared channel, or the total bit number of the second uplink control channel bearing information is larger than the first preset threshold value, and the terminal sends one of the first uplink shared channel and the second uplink control channel.
In this embodiment, the priority of the first uplink shared channel bearer information is lower than or equal to the priority of the second uplink control channel bearer information, and the terminal does not send the first uplink shared channel and sends the second uplink control channel; or the priority of the first uplink shared channel bearing information is greater than that of the second uplink control channel bearing information, and the terminal sends the first uplink shared channel and does not send the second uplink control channel.
For example, the priority of the information carried by the first uplink shared channel is determined by the information with the highest priority among the information carried by the first uplink shared channel; the priority of the information carried by the second uplink control channel is determined by the information with the highest priority in the information carried by the second uplink control channel. That is, in the second aspect, the information carried by the first uplink shared channel may include at least one of hybrid automatic repeat request acknowledgement information HARQ-ACK and channel state information; the information carried by the second uplink control channel comprises at least one uplink control information of hybrid automatic repeat request acknowledgement information (HARQ-ACK) and channel state information; wherein the priority of the HARQ-ACK is higher than the priority of the channel state information. Therefore, this embodiment is advantageous in transmitting the uplink control information with high priority to the network device based on the comparison of the priorities.
For another example, the priority among the AP-CSI, the P-CSI, the semi-CSI carried on the first uplink shared channel, and the semi-CSI carried on the first uplink control channel may be: the priority of the AP-CSI is higher than the priority of semi-CSI carried on an uplink shared channel; "priority of semi-CSI carried on uplink shared channel" is higher than "priority of semi-CSI carried on uplink control channel"; the "priority of semi-CSI carried on uplink control channel" is higher than the "priority of P-CSI". Therefore, when the information carried by the first uplink control channel is multiplexed with the information carried by the first uplink shared channel, the P-CSI in the first uplink control carrying information can be not multiplexed, i.e. discarded, so that the occupation proportion of the multiplexing mode to the resources of the first uplink shared channel can be reduced while the UCI with higher priority is sent to the network device.
In an alternative embodiment, the priority of the first uplink shared channel carrying information is determined by whether the first uplink shared channel carries hybrid automatic repeat request acknowledgement information HARQ-ACK; the priority of the second uplink control channel carrying information is determined by whether the second uplink control channel carries hybrid automatic repeat request acknowledgement information HARQ-ACK. Therefore, the embodiment is beneficial to transmitting the HARQ-ACK with high priority to the network equipment based on the comparison of the priority, so as to quickly retransmit the wrong data.
For example, as shown in fig. 3d, the resources occupied by the first uplink shared channel overlap with the resources occupied by the second uplink control channel, and the resources occupied by the first uplink control channel overlap with the resources occupied by the first uplink shared channel, referring to fig. 6, the channel transmission method may include the following steps:
301. the terminal determines resources occupied by a first uplink shared channel, the resources occupied by a second uplink control channel and the resources occupied by the first uplink control channel are overlapped, and the first uplink shared channel is associated with the first uplink control channel;
302. the terminal judges whether the first uplink control channel and the first uplink shared channel meet the time sequence condition, and if so, the terminal executes steps 303 to 304; if the timing condition is not satisfied, step 308 is performed;
303. Multiplexing part or all of the information carried by the first uplink control channel with the information carried by the first uplink shared channel in a punching or rate matching mode by the terminal, and carrying the information on the first uplink shared channel;
304. the terminal judges whether the resources occupied by the second uplink control channel are overlapped with the resources occupied by the DMRS corresponding to the first uplink shared channel, and whether the total bit number of the information carried by the second uplink control channel is smaller than or equal to a first preset threshold value; if the resources occupied by the second uplink control channel do not overlap with the resources occupied by the DMRS corresponding to the first uplink shared channel, and the total number of bits of the information carried by the second uplink control channel is less than or equal to the first preset threshold, step 307 is executed; if the resources occupied by the second uplink control channel overlap with the resources occupied by the DMRS corresponding to the first uplink shared channel, or the total number of bits of the information carried by the second uplink control channel is greater than the first preset threshold, executing step 305;
305. the terminal judges whether the priority of the first uplink shared channel bearing information is lower than or equal to the priority of the second uplink control channel bearing information; if the priority of the first uplink shared channel bearer information is lower than or equal to the priority of the second uplink control channel bearer information, then execution 308 is performed; if the priority of the first uplink shared channel bearer information is higher than the priority of the second uplink control channel bearer information, executing 306;
306. The terminal sends a first uplink shared channel, and does not send a first uplink control channel and a second uplink control channel;
307. the terminal adopts a mode of punching holes on the resources occupied by the first uplink shared channel, and transmits the first uplink shared channel and the second uplink control channel without transmitting the first uplink control channel;
308. the terminal transmits a first uplink control channel and a second uplink control channel, and does not transmit a first uplink shared channel.
In another alternative embodiment, the terminal may first determine how to transmit the non-associated uplink channel using the embodiment described in 2 above for the non-associated uplink channel; and further determining the transmission mode of the remaining overlapped uplink channels by combining the embodiment described in the above 1.
For example, as shown in fig. 3d, the uplink shared channel overlaps with both the uplink control channel and the second uplink control channel, and the terminal determines to transmit the second uplink control channel according to the embodiment described in the above 2, and when the uplink shared channel is not transmitted, the terminal may directly transmit the uplink control channel and the second uplink control channel without performing the operation in the embodiment described in the above 1; when the terminal determines not to transmit the second uplink control channel according to the embodiment described in the above 2 and transmits the uplink shared channel, the terminal needs to transmit one of the uplink shared channel and the uplink control channel in combination with the steps described in the embodiment described in the above 1; when the terminal determines to transmit the second uplink control channel and the uplink shared channel according to the embodiment described in the above 2, the terminal also needs to combine the steps described in the embodiment described in the above 1 to transmit one of the uplink shared channel and the uplink control channel, and the second uplink control channel.
4. Channel transmission method when resources occupied by multiple uplink channels overlap
In the channel transmission method, when the resources occupied by a plurality of uplink channels are overlapped, the uplink channels meeting the precondition of multiplexing in the first case can be multiplexed firstly aiming at the overlapped associated uplink channels; and secondly, determining which uplink channels are transmitted and which uplink channels are not transmitted according to the starting position and the occupied symbol length of each uplink channel aiming at the uplink channels after multiplexing, the associated uplink channels which cannot be multiplexed and the unassociated uplink channels. Or, the uplink channels meeting the precondition of multiplexing in the second case can be multiplexed firstly aiming at the overlapped non-associated uplink channels; and secondly, determining which uplink channels are transmitted and which uplink channels are not transmitted according to the starting position and the occupied symbol length of each uplink channel aiming at the uplink channels after multiplexing, the non-associated uplink channels which cannot be multiplexed and the associated uplink channels. Alternatively, when the resources occupied by the plurality of uplink channels overlap, the transmission scheme of the plurality of uplink channels may be determined simply based on the start position of each uplink channel and the occupied symbol length.
For example, for a plurality of uplink channels with overlapped occupied resources, determining an uplink channel with a more front or forefront position of a start symbol, determining an uplink channel with a longest occupied symbol from the uplink channels with a more front or forefront position of the start symbol, transmitting the uplink channel with the longest occupied symbol, and not transmitting other uplink channels overlapped with the resources occupied by the uplink channel with the longest occupied symbol; and executing the method for the uplink channels with the overlapped remaining multiple occupied resources.
For another example, if the above-described multiplexing is performed on the associated PUSCH1 and PUSCH1, and the multiplexed PUSCH1 is also overlapped with the unassociated PUCCH2, the terminal may determine the upstream channel further forward or forward-most in the position of the start symbol from among the multiplexed PUSCH1 and the unassociated PUCCH2, and if the upstream channel is the multiplexed PUSCH1, the terminal may transmit the multiplexed PUSCH1 and may not transmit the PUCCH2 overlapped therewith. As another example, as shown in fig. 3d, the upstream channel where the start symbol is transmitted is the first upstream control channel, and thus, the terminal may transmit only the first upstream control channel and not transmit the first upstream shared channel and the second upstream control channel.
For another example, if the starting positions of the plurality of overlapped uplink channels are the same, the uplink channel with the longest symbol is determined, and other uplink channels with the resources overlapping with the resources occupied by the uplink channel are not transmitted; if there are more uplink channels with the longest occupied symbols, the transmission scheme can be determined continuously according to the front and back of the starting position. For example, if PUSCH1 is the same as the starting position of the unassociated PUCCH2, but the symbol occupied by PUCCH2 is longest, the terminal does not transmit PUSCH1 and transmits PUCCH2. As shown in fig. 3e, if the initial positions of the first uplink shared channel and the first uplink control channel are the same, and the first uplink shared channel overlaps with both the first uplink control channel and the second uplink control channel, the terminal may transmit only the first uplink shared channel, and not transmit the first uplink control channel and the second uplink control channel overlapping with the first uplink shared channel.
In another example, for a plurality of uplink channels with overlapped occupied resources, determining the uplink channel with the longest occupied symbol, determining the uplink channel with the earlier or forefront position of the starting symbol from the uplink channels with the longest occupied symbol, transmitting the uplink channel with the earlier or forefront position of the starting symbol, and not transmitting other uplink channels with overlapped resources occupied by the uplink channel with the earlier or forefront position of the starting symbol; and executing the method for the uplink channels with the overlapped remaining multiple occupied resources.
In yet another example, if the lengths of the symbols occupied by the overlapped uplink channels are the same, the uplink channel whose position of the start symbol is earlier or forefront is transmitted, and the other uplink channel whose occupied resource overlaps with the resource occupied by the uplink channel whose position of the start symbol is earlier or forefront is not transmitted. That is, the embodiments of the present application are not limited to the above examples, and may be, for example, the transmission with the last start position and/or the shortest occupied symbol, and the rest are not transmitted. For example, an alternative channel transmission method may be selected in conjunction with an application scenario.
In yet another alternative embodiment, in some application scenarios, the channel transmission method may include: once the resources occupied by the multiple uplink channels overlap, the terminal may not transmit all of the overlapping uplink channels. For example, as shown in fig. 3d, the terminal may not transmit the first uplink control channel, the first uplink shared channel, and the second uplink control channel.
In yet another alternative embodiment, the channel transmission method may include: the resources occupied by the plurality of uplink channels overlap, the uplink shared channel is preferentially sent, and the uplink control channel is discarded; or the uplink control channel is preferentially sent, and the uplink shared channel is discarded. For example, as shown in fig. 3d, the terminal may only transmit the first uplink shared channel, and not transmit the first uplink control channel and the second uplink control channel; or the terminal only transmits the first uplink control channel and the second uplink control channel, and does not transmit the first uplink shared channel.
It can be seen that the manner of determining how to transmit the overlapped uplink channels in the embodiments described in the above 4 is relatively simple, so that the processing load of the terminal can be greatly reduced, and the uplink channels with early or occupied symbols can be preferentially transmitted.
5. Another channel transmission method when the resources occupied by multiple uplink channels overlap
The present application also provides a channel transmission method, in which a terminal can learn that resources occupied by associated uplink channels overlap, and resources occupied by non-associated uplink channels also overlap, and the terminal can determine transmission schemes of the uplink channels by itself. The associated uplink channels may be multiplexed when the preconditions described above are satisfied. Therefore, the terminal may have the following options for overlapping the resources occupied by the first uplink shared channel with the resources occupied by the first uplink control channel and the resources occupied by the second uplink control channel, and have enough degrees of freedom.
For example, the terminal may transmit the first uplink control channel and the second uplink control channel, respectively, without transmitting the first uplink shared channel.
For another example, when the first uplink control channel and the first uplink shared channel meet the timing sequence condition, the terminal multiplexes part or all of the information carried by the first uplink control channel with the information carried by the first uplink shared channel, carries the multiplexed information on the first uplink shared channel, and then sends at least one of the first uplink shared channel and the second uplink control channel according to an optional rule, such as the channel transmission method described in the 2 nd point.
For another example, when determining that the second uplink control channel includes HARQ-ACK, the terminal may transmit the first uplink control channel and the second uplink control channel, respectively, without transmitting the first uplink shared channel.
For another example, the terminal may select to transmit the uplink channel with the initial symbol earlier or the symbol length of the uplink channel preferentially according to the channel transmission method described in the above 4 th point.
For the network device side, the network device corresponding to the first uplink control channel and the first uplink shared channel is not aware of the transmission scheme selected by the terminal. Thus, in an alternative embodiment, the network device may detect the first uplink control channel twice for the first uplink control channel, that is, detect the first uplink control channel on the resources of the first uplink control channel and detect the first uplink shared channel on the resources of the first uplink shared channel, so that the network device obtains the uplink control information. Wherein the uplink control information is from the first uplink control channel or from the first uplink shared channel. Specifically, if the first uplink control channel is successfully detected on the resource of the first uplink control channel, the uplink control information is from the first uplink channel. If the first uplink control channel fails to be detected on the resource uplink of the first uplink control channel, uplink control information is detected on the resource of the first uplink shared channel, wherein the uplink control information is uplink control information after multiplexing the uplink control information carried by the first uplink control channel and the uplink control information carried by the first uplink shared channel.
That is, the network device receives the first uplink control channel on the resources of the first uplink control channel and receives the first uplink shared channel on the first uplink shared channel. The network equipment does not receive the first uplink control channel, and then acquires part or all of information in the first uplink control channel bearing information and information borne by the first uplink shared channel from the received first uplink shared channel; the first uplink control channel is associated with the first uplink shared channel. It can be seen that the network device associated with the first uplink control channel and the first uplink shared channel needs to detect more than once. And if the network equipment corresponding to the second uplink control channel detects the information, the decoding is successful; if no information is detected, decoding failure is indicated.
