The technical solution in the present application will be described below with reference to the accompanying drawings.
The technical scheme of the embodiment of the application can be applied to various communication systems, for example: a future fifth Generation (5G) system, a New Radio (NR) system, or a communication system having the same architecture as the 5G system.
Terminal equipment in the embodiments of the present application may refer to user equipment, access terminals, subscriber units, subscriber stations, mobile stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents, or user devices. The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G Network or a terminal device in a future evolved Public Land Mobile Network (PLMN), and the like, which are not limited in this embodiment.
The Network device in this embodiment may be a device for communicating with a terminal device, where the Network device may be a Base Transceiver Station (BTS) in a Global System for Mobile communication (GSM) System or a Code Division Multiple Access (CDMA) System, may also be a Base Station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) System, may also be an evolved node b (eNB, eNodeB) in an LTE System, may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or may be a relay Station, an Access point, a vehicle-mounted device, a wearable device, a Network device in a future 5G Network, a Network device in a future evolved PLMN Network, and the like, and the embodiment of the present invention is not limited.
Fig. 1 is a schematic diagram of a possible application scenario of an embodiment of the present application. The communication system shown in fig. 1 includes a network device and a terminal device, and the terminal device may transmit various UCI to the network device, so that a base station can perform management of radio resources and scheduling decision according to the UCI. It should be understood that fig. 1 only shows a communication system composed of one terminal device and one network device, and in fact, the embodiments of the present application may also be applied to a communication system composed of a plurality of terminal devices and network devices, where each terminal device may transmit its respective UCI to the network device as needed.
In the existing LTE system, a terminal device is only configured with authorized time-frequency resources, and the terminal device needs to send UCI to a network device through the authorized time-frequency resources, that is, the terminal device can only transmit UCI to the network device using a single time-frequency resource. Therefore, in the present application, a terminal device is configured with an authorized time-frequency resource and an unlicensed time-frequency resource, so that the terminal device can flexibly select a time-frequency resource used for transmitting UCI from the authorized time-frequency resource and the unlicensed time-frequency resource, thereby improving flexibility of the terminal device in transmitting UCI.
The method for transmitting uplink control information according to the embodiment of the present application is described in detail below with reference to fig. 2.
Fig. 2 is a schematic flowchart of a method for transmitting uplink control information according to an embodiment of the present application. The method of fig. 2 may be performed by a terminal device. The method 200 of fig. 2 includes:
210. the terminal equipment determines a target Channel from a plurality of channels, wherein the plurality of channels comprise a Grant Free Physical Uplink Shared Channel (GF-PUSCH) and a GB-PUSCH.
Alternatively, the terminal device may arbitrarily select one channel from GF-PUSCH and GB-PUSCH as the target channel.
Optionally, the terminal device may also select a target channel from the multiple channels according to an indication of the network device.
Specifically, the terminal device receives first indication information sent by the network device, and the determining, by the terminal device, a target channel from a plurality of channels includes: and the terminal equipment selects GF-PUSCH or GB-PUSCH from the plurality of channels as a target channel according to the first indication information. The first indication information is used for indicating the terminal equipment to preferentially select GF-PUSCH or GB-PUSCH from a plurality of channels as a target channel.
It should be understood that the above multiple channels may include a Physical Uplink Control Channel (PUCCH) in addition to the GB-PUSCH and the GF-PUSCH, that is, the terminal device may select a Control Channel as a target Channel in addition to the data Channel.
220. And the terminal equipment sends UCI to the network equipment through the target channel.
In the present application, the terminal device can flexibly select a target channel from a plurality of channels and transmit UCI when GF-PUSCH and GF-PUSCH are configured, and can more flexibly select resources for transmitting UCI than a scheme in which UCI can be transmitted only on GB-PUSCH and PUCCH in the prior art.
It should be understood that the above-mentioned first indication information is indicative of the terminal device selecting the GF-PUSCH or the GB-PUSCH from the plurality of channels as the target channel (that is, the first indication information indicates that the terminal device selects the target channel from the GF-PUSCH and the GB-PUSCH from the plurality of channels), and further indicates whether the terminal device preferentially selects the GF-PUSCH or the GB-PUSCH as the target channel (equivalent to indicating the priority of the GB-PUSCH and the GF-PUSCH).
Optionally, the first indication information may be carried in RRC signaling or DCI sent by the network device to the terminal device, and therefore, a new field may be added in the RRC signaling and Downlink Control Information (DCI) to indicate the first indication information.
The first indication information may instruct the terminal apparatus to preferentially select the GF-PUSCH as the target channel from among the plurality of channels (the priority corresponding to the GF-PUSCH is higher than the GB-PUSCH), or instruct the terminal apparatus to preferentially select the GB-PUSCH as the target channel from among the plurality of channels (the priority corresponding to the GB-PUSCH is higher than the GF-PUSCH). The following describes the two cases in detail with reference to the first and second examples.
Example one: the priority of GF-PUSCH is higher than that of GB-PUSCH
In an example one, when the priority of the GF-PUSCH is higher than that of the GB-PUSCH, the method for the terminal device to determine the target channel from the multiple channels may be divided into two types according to the relationship between the terminal device transmitting the UCI and the terminal device transmitting the uplink data.
The first method is as follows: when UCI is transmitted on a data channel, UCI must be transmitted together with uplink data
In the first mode, the terminal device selects the target channel according to the first indication information and whether the terminal device transmits uplink data.
Specifically, the terminal device selects a GF-PUSCH or a GB-PUSCH as a target channel from a plurality of channels according to the first indication information, including: the terminal equipment determines whether to send uplink data in GF-PUSCH or not; if uplink data are sent on the GF-PUSCH, the terminal equipment selects the GF-PUSCH as a target channel; if the uplink data is not sent on the GF-PUSCH, the terminal equipment determines whether the uplink data is sent on the GB-PUSCH or not; and if the uplink data is sent on the GB-PUSCH, the terminal equipment selects the GB-PUSCH as a target channel.
It should be understood that, in the first mode, if the terminal device does not transmit uplink data on the GB-PUSCH nor the GF-PUSCH, the terminal device transmits UCI on the uplink control channel PUCCH.
In the first mode, when UCI is transmitted on a data channel, UCI must be transmitted with uplink data, otherwise UCI can only be transmitted on PUCCH. Therefore, when the terminal equipment does not transmit the uplink data on the GF-PUSCH or transmits the uplink data on the GB-PUSCH, the terminal equipment selects the PUCCH as the target channel.
How the terminal device sends UCI to the network device in the first mode is described in detail below with reference to fig. 3.
As shown in fig. 3, a specific process of the terminal device sending UCI to the network device is as follows:
310. the terminal equipment needs to send UCI to the network equipment at the current time slot;
320. the terminal equipment determines whether uplink data needs to be sent in the current time slot;
330. if uplink data which needs to be sent exists in the current time slot, the terminal equipment determines whether GF-PUSCH data exists or not;
340. if the GF-PUSCH data exists, the terminal equipment transmits UCI on the GF-PUSCH;
350. if the GF-PUSCH data does not exist, the terminal equipment transmits UCI on GB-PUSCH;
360. and if the uplink data does not exist in the current time slot, the terminal equipment transmits UCI on the PUCCH.
It should be understood that, in step 330, in the case that the terminal device determines whether there is GF-PUSCH data corresponding to uplink data that needs to be transmitted on the GF-PUSCH in the current time slot, the terminal device determines whether the uplink data is transmitted on the GF-PUSCH.
Taking the specific flow shown in fig. 3 as an example, when the first indication information is carried in the RRC signaling, the specific format of the RRC signaling is as follows:
the PUCCH-ConfigDedicated is a PUCCH configuration message dedicated to the terminal device, and includes a plurality of fields, where each field has the following meaning: the value of simultaneousUCCH-PUSCH field is false, which indicates that the terminal equipment cannot simultaneously transmit PUCCH and PUSCH, so that the terminal equipment can only transmit all UCI on the PUSCH; the UCIonPUSCH is a data channel-related field, and the subfield priority on PUSCH with grant takes a value of true, which indicates that the terminal device preferentially selects the GB-PUSCH when selecting the target channel.
It should be understood that, in the above RRC signaling, a field may also be set to indicate that UCI must be transmitted together with uplink data when transmitting on the data channel.
Optionally, in the first mode, the terminal device may send all UCI to be transmitted to the network device on a data channel (GF-PUSCH or GB-PUSCH), or may send only a part of UCI of all UCI to be transmitted to the network device, and the remaining part of UCI may be transmitted on the PUCCH.
Specifically, as shown in fig. 4, a specific process of the terminal device sending UCI to the network device is as follows:
410. the terminal equipment needs to send UCI to the network equipment at the current time slot;
420. the terminal equipment determines whether uplink data needs to be sent in the current time slot;
430. if uplink data need to be sent in the current time slot, the terminal equipment determines whether GF-PUSCH data exist or not;
440. if the GF-PUSCH data exists, the terminal equipment transmits all UCI or partial UCI on the GF-PUSCH;
450. if the GF-PUSCH data does not exist, the terminal equipment transmits all UCI or partial UCI on the GB-PUSCH;
460. and if the current time slot has no uplink data, the terminal equipment transmits all UCI on the PUCCH.
It should be understood that, in steps 450 and 460, the total UCI refers to the total UCI that the terminal device is currently about to transmit to the network device.
Taking the flow shown in fig. 4 as an example, when the first indication information is carried in the RRC signaling, a specific format of the RRC signaling is as follows:
the PUCCH-ConfigDedicated is a PUCCH configuration message dedicated to the terminal device, and includes a plurality of fields, where each field has the following meaning: the value of simultaneousucch-PUSCH field is true, which indicates that the terminal device can simultaneously transmit PUCCH and PUSCH, so the terminal device can transmit part of UCI on PUSCH and another part of UCI on PUCCH; the UCIonPUSCH is a field related to a data channel, and a subfield primaryonpusch with a value of false indicates that the terminal device does not preferentially select the GB-PUSCH, that is, preferentially selects the GF-PUSCH, when selecting the target channel.
It should be understood that, in the above RRC signaling, a field may also be set to indicate that UCI must be transmitted together with uplink data when transmitting on the data channel.
The second method comprises the following steps: UCI may be transmitted separately on a data channel
In the second mode, the terminal device does not need to determine whether uplink data exists on the GF-PUSCH, but directly uses the GF-PUSCH as a target channel and transmits UCI through the GF-PUSCH.
Specifically, the selecting, by the terminal device, the GF-PUSCH or GB-PUSCH from the multiple channels as the target channel according to the first indication information specifically includes: and the terminal equipment selects the GF-PUSCH as the target channel.
It should be understood that, in the second mode, after the terminal selects the GF-PUSCH as the target channel, the UCI may be transmitted on the GF-PUSCH alone or simultaneously with the uplink data when the UCI is subsequently transmitted on the GF-PUSCH.
Example two: the priority of GB-PUSCH is higher than that of GF-PUSCH
Similar to the first example, in the second example, when the priority of the GB-PUSCH is higher than that of the GF-PUSCH, the method for the terminal device to determine the target channel from the multiple channels may be divided into two types according to the relationship between the terminal device transmitting the UCI and the terminal device transmitting the uplink data.
The third method comprises the following steps: the UCI must be transmitted along with the uplink data when transmitted on the data channel.
In the third mode, the terminal device selects the target channel according to the first indication information and whether the terminal device transmits uplink data.
Specifically, the selecting, by the terminal device, the GF-PUSCH or GB-PUSCH from the multiple channels as the target channel according to the first indication information specifically includes: the terminal equipment determines whether to send uplink data in GB-PUSCH or not; if uplink data are sent on the GB-PUSCH, the terminal equipment selects the GB-PUSCH as a target channel; if the uplink data is not sent on the GB-PUSCH, the terminal equipment determines whether the uplink data is sent on the GF-PUSCH or not; and if the uplink data is sent on the GF-PUSCH, the terminal equipment selects the GF-PUSCH as a target channel.
In the third mode, when UCI is transmitted on a data channel, UCI must be transmitted with uplink data, otherwise UCI can only be transmitted on PUCCH. Therefore, when the terminal equipment does not transmit the uplink data on the GB-PUSCH or transmits the uplink data on the GF-PUSCH, the terminal equipment selects the PUCCH as the target channel.
How the terminal device sends UCI to the network device in the third mode is described in detail below with reference to fig. 5.
As shown in fig. 5, a specific process of the terminal device sending UCI to the network device is as follows:
510. the terminal equipment needs to send UCI to the network equipment at the current time slot;
520. the terminal equipment determines whether uplink data needs to be sent in the current time slot;
530. if the uplink data in the current time slot need to be sent, the terminal equipment determines whether GB-PUSCH data exist or not;
540. if the GB-PUSCH data exists, the terminal equipment sends UCI on the GB-PUSCH;
550. if the GB-PUSCH data does not exist, the terminal equipment transmits UCI on the GF-PUSCH;
560. and if the uplink data does not exist in the current time slot, the terminal equipment transmits UCI on the PUCCH.
It should be understood that, in step 530, the terminal device determines whether there is GB-PUSCH data corresponding to the uplink data that needs to be transmitted in the current slot, and then determines whether the uplink data is transmitted on GB-PUSCH.
In addition, in the third mode, the terminal device may send all UCI to be transmitted to the network device on a data channel (GF-PUSCH or GB-PUSCH), or may send only a part of UCI of all UCI to be transmitted to the network device, and the remaining part of UCI may be transmitted on the PUCCH.
Specifically, as shown in fig. 6, a specific process of the terminal device sending UCI to the network device is as follows:
610. the terminal equipment needs to send UCI to the network equipment at the current time slot;
620. the terminal equipment determines whether uplink data needs to be sent in the current time slot;
630. if uplink data need to be sent in the current time slot, the terminal equipment determines whether GB-PUSCH data exist or not;
640. if the GB-PUSCH data exists, the terminal equipment sends all UCI or part of UCI on the GB-PUSCH;
650. if the GB-PUSCH data does not exist, the terminal equipment transmits all UCI or part of UCI on the GF-PUSCH;
660. if the current time slot has no uplink data, the terminal equipment sends all UCI or part of UCI on the PUCCH;
the method is as follows: UCI may be transmitted separately on a data channel
In the fourth mode, the terminal device does not need to determine whether uplink data exists on the GB-PUSCH, but directly uses the GB-PUSCH as a target channel, and transmits UCI through the GB-PUSCH.
Specifically, the selecting, by the terminal device, the GF-PUSCH or GB-PUSCH from the multiple channels as the target channel according to the first indication information specifically includes: and the terminal equipment selects the GB-PUSCH as the target channel.
It should be understood that, in the fourth mode, after the terminal selects the GB-PUSCH as the target channel, the UCI may be transmitted on the GB-PUSCH separately or simultaneously with the uplink data when the UCI is transmitted on the GB-PUSCH subsequently.
It should be understood that, although it is described above that the terminal device may determine the target channel according to the priority information indicated by the first indication information, in fact, the terminal device may also determine the target channel in other manners, for example, the terminal device may determine the target channel directly according to the type of UCI to be transmitted currently.
Optionally, as an embodiment, in step 210, the determining, by the terminal device, the target channel from the multiple channels specifically includes: and the terminal equipment selects GF-PUSCH or GB-PUSCH as a target channel according to the type of the UCI.
The terminal device can select a data channel matched with the type of the UCI according to the type of the UCI, and the effect of transmitting the UCI can be improved.
Optionally, when the terminal device selects the GF-PUSCH or the GB-PUSCH as the target channel according to the type of the UCI, the terminal device may select the GF-PUSCH or the GB-PUSCH as the target channel according to the type of the UCI according to a relationship between transmission of the UCI by the terminal device and transmission of uplink data by the terminal device, and the terminal device may be divided into two cases according to the type of the UCI, which are described in detail below with reference to the third example and the fourth example.
Example three: UCI may be transmitted separately on a data channel
It should be understood that, in the third example, the UCI does not need to be sent together with the uplink data, and therefore, after the terminal device determines the type of the UCI, the terminal device may directly select a physical uplink data channel corresponding to the type of the UCI as a target channel.
Optionally, the determining, by the terminal device, a target channel from a plurality of channels includes: under the condition that the type of the UCI belongs to the first type, the terminal equipment selects GF-PUSCH as the target channel; under the condition that the type of the UCI belongs to a second type, the terminal equipment selects GB-PUSCH as the target channel; wherein the first type and the second type are different.
Specifically, as shown in fig. 7, the specific process of the terminal device selecting a target channel according to the type of the UCI and sending the UCI on the target channel includes:
710. the terminal equipment needs to send UCI to the network equipment at the current time slot;
720. the terminal equipment determines the type of UCI;
730. transmitting the UCI on a GF-PUSCH on a condition that the type of the UCI belongs to a first type;
740. transmitting the UCI on a GB-PUSCH in case that the type of the UCI belongs to a second type.
Example four: when UCI is transmitted on a data channel, UCI must be transmitted together with uplink data
It should be understood that, in the fourth example, if the UCI is transmitted on a data channel, the UCI must be transmitted together with uplink data, that is, after the data channel corresponding to the UCI is determined according to the type of the UCI, it is further determined whether uplink data needs to be transmitted on the data channel corresponding to the UCI, and if there is no uplink data that needs to be transmitted, the UCI may be transmitted on the PUCCH.
Optionally, the determining, by the terminal device, the target channel from the multiple channels specifically includes: under the condition that the type of UCI belongs to a first type, the terminal equipment determines whether to transmit uplink data in a GF-PUSCH; if uplink data are sent on the GF-PUSCH, the terminal equipment selects the GF-PUSCH as the target channel; and under the condition that the type of the UCI belongs to a second type, the terminal equipment determines whether to transmit uplink data in GB-PUSCH or not; and if the uplink data is sent on the GB-PUSCH, the terminal equipment selects the GB-PUSCH as a target channel.
Specifically, as shown in fig. 8, the specific process of the terminal device selecting a target channel according to the type of the UCI and sending the UCI on the target channel includes:
810. the terminal equipment needs to send UCI to the network equipment at the current time slot;
820. the terminal equipment determines the type of UCI;
830. under the condition that the type of UCI belongs to a first type, the terminal equipment determines whether to transmit uplink data on a GF-PUSCH or not;
840. when the terminal equipment determines that the uplink data is sent on the GF-PUSCH, the terminal equipment sends UCI on the GF-PUSCH;
850. when the terminal equipment determines that uplink data are not sent on the GF-PUSCH, the terminal equipment sends UCI on a PUCCH;
860. under the condition that the type of the UCI belongs to a second type, the terminal equipment determines whether to transmit uplink data on a GB-PUSCH or not;
870. when the terminal equipment determines that uplink data are sent on a GB-PUSCH, the terminal equipment sends UC on the GB-PUSCH;
880. and when the terminal equipment determines that the uplink data is not transmitted on the GB-PUSCH, the terminal equipment transmits the UCI on the PUCCH.
Optionally, in example three and example four, the first type of UCI includes UCI that needs to be periodically transmitted, and the second type of UCI includes UCI that does not need to be periodically transmitted.
Specifically, the first type of UCI includes periodic Channel State Information CSI, and the second type of UCI includes at least one of aperiodic Channel State Information (CSI), ACK, and NACK Information.
The periodic information is suitable for transmission on the GF-PUSCH in a similar manner as the configuration of the unlicensed resources, while the aperiodic information, such as ACK/NACK, generally corresponds to dynamic scheduling and is suitable for transmission on the GB-PUSCH.
Optionally, as an embodiment, when the terminal device is configured with multiple GF-PUSCHs, the method 200 further includes: and the terminal equipment receives second indication information sent by the network equipment, wherein the second indication information is used for indicating a target GF-PUSCH which can be used for the terminal equipment to send the UCI to the network equipment in the GF-PUSCHs.
It should be understood that the second indication information may be carried in RRC signaling or DCI sent by the network device to the terminal device, and therefore, the second indication information may be represented by adding a new field in the RRC signaling or DCI.
It should be understood that when the terminal device is configured with a plurality of GF-PUSCHs, the target GF-PUSCH employed in the transmission of UCI may be determined from the plurality of GF-PUSCHs according to an instruction of the network device, or the target GF-PUSCH may be determined from the plurality of GF-PUSCHs by the terminal device itself.
In addition, when the terminal device is configured with a plurality of GF-PUSCHs, the terminal device may indicate whether a certain GF-PUSCH transmits UCI by adding a different sequence to GF-PUSCH data. Specifically, as shown in fig. 9, when the GF-PUSCH data transmitted by the terminal device includes the first sequence, it indicates that the GF-PUSCH data includes both uplink data and UCI; and when the GF-PUSCH data transmitted by the terminal equipment contains the second sequence, the GF-PUSCH data only contains uplink data and does not contain UCI. In addition, in fig. 9, when UCI is transmitted together with uplink data, UCI and uplink data occupy different time domain resources. Actually, as shown in fig. 10, when UCI is transmitted together with uplink data, the UCI may occupy a different frequency domain resource from the uplink data. That is, when UCI is transmitted through the GF-PUSCH channel, UCI and uplink data may be time division multiplexed or frequency division multiplexed. It should be understood that the first sequence and the second sequence may be time division multiplexed or frequency division multiplexed with uplink data.
The first sequence and the second sequence may be different Reference Signal (RS) sequences, for example, the first sequence may be RS1, the second sequence may be RS2, after receiving the GF-PUSCH data, the network device determines whether the GF-PUSCH data includes UCI by detecting the RS sequence, and if the network device detects RS1 in the received GF-PUSCH data, the network device determines that the GF-PUSCH data includes UCI (at this time, the GF-PUSCH data includes uplink data and UCI); and if the network device detects the RS2 in the received GF-PUSCH data, the network device determines that the GF-PUSCH does not contain UCI (in this case, the GF-PUSCH data contains only uplink data).
When the terminal equipment is configured with a plurality of GF-PUSCHs, the terminal equipment adds different sequences into GF-PUSCH data, so that the network equipment can identify whether UCI is contained in a GF-PUSCH channel, and the network equipment can correctly analyze the data transmitted on the GF-PUSCH.
Alternatively, when the terminal device transmits UCI on the GF-PUSCH, only uplink data may be transmitted on the GF-PUSCH, or both uplink data and UCI may be transmitted on the GF-PUSCH, and in order to distinguish between the two cases, the terminal device may instruct the GF-PUSCH channel to transmit only UCI or both UCI and uplink data by transmitting a different Demodulation Reference Signal (DMRS) to the network device.
Specifically, when the terminal device sends the DMRS1 to the network device, the terminal device indicates that the GF-PUSCH data only includes UCI and does not include uplink data; and when the terminal device sends DMRS2 to the network device, the terminal device indicates that the GF-PUSCH data includes both UCI and uplink data.
The network equipment can determine the UCI sending condition of the terminal equipment according to the detected DMRS, and errors are avoided when the network equipment identifies GF-PUSCH data.
While the method for transmitting UCI of the embodiment of the present application is described in detail from the perspective of the terminal device in conjunction with fig. 2 to 10, and described below from the perspective of the network device in conjunction with fig. 11, it should be understood that the method for transmitting UCI of the embodiment of the present application described below from the perspective of the network device corresponds to the method for transmitting UCI of the embodiment of the present application described above from the perspective of the terminal device, and repeated description is appropriately omitted below for the sake of brevity.
Fig. 11 is a schematic flowchart of a method for transmitting uplink control information according to an embodiment of the present application. The method of fig. 11 may be performed by a network device. The method 1100 of FIG. 11 includes:
1110. the network equipment determines a target channel from a plurality of channels, wherein the plurality of channels comprise an unlicensed physical uplink shared channel GF-PUSCH and a licensed physical uplink shared channel GB-PUSCH.
It is to be appreciated that in step 1110, the terminal device can determine the target channel from the plurality of channels in the same manner as the terminal device. Specifically, the terminal device may arbitrarily select one channel from GF-PUSCH and GB-PUSCH as a target channel, and transmit indication information to the network device, where the indication information is used to indicate which channel the terminal device selects as the target channel, and after receiving the indication information, the network device may determine the target channel according to the indication information, so that the target channel determined by the network device is consistent with the target channel determined by the terminal device.
In addition, the network device and the terminal device may also determine the target channel from the multiple channels according to a predetermined rule and manner (specifically, a rule or manner specified in a communication standard or protocol).
Alternatively, the network device may determine the target channel from the GF-PUSCH and the GB-PUSCH according to the priorities of the GF-PUSCH and the GB-PUSCH (the priorities of the GF-PUSCH and the GB-PUSCH may be predetermined).
In addition, the network device may further transmit, to the terminal device, first indication information for instructing the terminal device to preferentially select the GF-PUSCH or the GB-PUSCH as the target channel from the plurality of channels. In this way, the terminal device, after receiving the first indication information, can preferentially select the GF-PUSCH or the GB-PUSCH as the target channel from the plurality of channels according to the priorities of the GF-PUSCH and the GB-PUSCH.
Optionally, before the network device receives the UCI sent by the terminal device from the target channel, the method 1100 further includes: the network equipment sends first indication information to the terminal equipment, wherein the first indication information is used for indicating the terminal equipment to preferentially select GF-PUSCH or GB-PUSCH from a plurality of channels as a target channel.
Optionally, the first indication information may be carried in RRC signaling or DCI transmitted by the network device to the terminal device, and therefore, the first indication information may be represented by adding a new field in the RRC signaling or DCI.
It should be understood that the above-mentioned multiple channels may also include PUCCH in addition to GB-PUSCH and GF-PUSCH, that is, the terminal device may also select a control channel as a target channel in addition to a data channel as a target channel.
1120. And the network equipment receives the UCI transmitted by the terminal equipment from the target channel.
In the present application, the network device can flexibly select a target channel from a plurality of channels to transmit UCI when GF-PUSCH and GF-PUSCH are configured, and can more flexibly select resources for transmitting UCI than a scheme in which UCI can be transmitted only on GB-PUSCH and PUCCH in the prior art.
Optionally, as an embodiment, when the first indication information is specifically used to instruct the terminal device to preferentially select the GF-PUSCH from the multiple channels as the target channel, the determining, by the network device, the target channel from the multiple channels includes: the network equipment determines whether uplink data are transmitted on the GF-PUSCH or not; if uplink data are transmitted on the GF-PUSCH, the network equipment selects the GF-PUSCH as a target channel; if no uplink data is transmitted on the GF-PUSCH, the network equipment determines whether the uplink data is transmitted on the GB-PUSCH; and if the uplink data are transmitted on the GB-PUSCH, the network equipment selects the GB-PUSCH as a target channel. It should be appreciated that in this case, the UCI must be transmitted along with the uplink data when transmitted on the data channel.
Specifically, when the priority of the GF-PUSCH is higher, the terminal device further determines the target channel according to whether uplink data exists in the GF-PUSCH. This way of determining the target channel is similar to the way of determining the target channel by the terminal device in the first way of the first example above. And will not be described in detail herein.
Optionally, as an embodiment, when the first indication information is specifically used to indicate that the terminal device preferentially selects a GB-PUSCH from multiple channels as a target channel, the determining, by the network device, the target channel from the multiple channels includes: the network equipment determines whether uplink data are transmitted on a GB-PUSCH or not; if uplink data are transmitted on the GB-PUSCH, the network equipment selects the GB-PUSCH as a target channel; if no uplink data is transmitted on the GB-PUSCH, the network equipment determines whether the uplink data is transmitted on the GF-PUSCH or not; and if uplink data are transmitted on the GF-PUSCH, the network equipment selects the GF-PUSCH as a target channel. It should be appreciated that in this case, the UCI must be transmitted along with the uplink data when transmitted on the data channel.
Specifically, when the priority of the GB-PUSCH is higher, the terminal device further determines the target channel according to whether there is uplink data in the GB-PUSCH. This way of determining the target channel is similar to the way of determining the target channel by the terminal device in the third way of the second example above. And will not be described in detail herein.
Alternatively, when UCI may be transmitted separately on a data channel, the network device may directly determine the target channel according to the priority information of the GF-PUSCH and the GB-PUSCH.
Specifically, when UCI can be separately transmitted on a data channel, if the first indication information is used to instruct the terminal device to preferentially select the GF-PUSCH from multiple channels as the target channel, the network device determines the target channel from the multiple channels, including: and the network equipment selects the GF-PUSCH as a target channel. In this case, the network device determines the target channel in a manner similar to that of the terminal device in the second manner of the first example. And will not be described in detail herein.
If the first indication information is specifically used for indicating the terminal device to preferentially select the GB-PUSCH from the multiple channels as the target channel, then the network device determines the target channel from the multiple channels, including: and the network equipment selects GB-PUSCH as a target channel. In this case, the network device determines the target channel in a manner similar to that of the terminal device in the fourth manner of the second example above. And will not be described in detail herein.
Alternatively, the network device may determine the target channel directly according to the content of the UCI, in addition to determining the target channel according to the priority information. It should be understood that it is possible to predetermine in advance that both the network device and the terminal device determine the target channel according to the content of the UCI.
Optionally, as an embodiment, the determining, by the network device, a target channel from a plurality of channels includes: and the network equipment selects GF-PUSCH or the GB-PUSCH as the target channel according to the type of the UCI.
The network device may select a data channel matched with the type of the UCI according to the type of the UCI, which may improve an effect of transmitting the UCI.
Optionally, the network device determines the target channel from a plurality of channels, including: under the condition that the type of the UCI belongs to a first type, the network equipment selects GF-PUSCH as a target channel; and under the condition that the type of the UCI belongs to a second type, the network equipment selects GB-PUSCH as a target channel, wherein the first type and the second type are different. It should be understood that, at this time, the network device determines the target channel without considering whether there is uplink data or not, but directly determining the target channel according to the type of the UCI, in which case, the network device determines the target channel in a manner similar to that of the terminal device in the third example above. And will not be described in detail herein.
Optionally, the network device determines the target channel from a plurality of channels, including: under the condition that the type of the UCI belongs to a first type, the network equipment determines whether uplink data are transmitted on a GF-PUSCH or not; if uplink data are transmitted on the GF-PUSCH, the network equipment selects the GF-PUSCH as a target channel; under the condition that the type of the UCI belongs to a second type, the network equipment determines whether uplink data are transmitted on a GB-PUSCH or not; if uplink data are transmitted on the GB-PUSCH, the network equipment selects the GB-PUSCH as a target channel; wherein the first type and the second type are different. It should be understood that, at this time, the network device needs to consider whether there is uplink data when determining the target channel, and at this time, the network device determines the target channel according to the type of the UCI and whether there is uplink data, in which case, the network device determines the target channel in a manner similar to that of the terminal device determining the target channel in the fourth example above. And will not be described in detail herein.
Optionally, the first type of UCI includes UCI that needs to be periodically transmitted, and the second type of UCI includes UCI that does not need to be periodically transmitted.
Specifically, the first type of UCI includes periodic Channel State Information CSI, and the second type of UCI includes at least one of aperiodic Channel State Information (CSI), ACK, and NACK Information.
The periodic information is suitable for transmission on the GF-PUSCH in a similar manner as the configuration of the unlicensed resources, while the aperiodic information, such as ACK/NACK, generally corresponds to dynamic scheduling and is suitable for transmission on the GB-PUSCH.
Optionally, as an embodiment, when the terminal device is configured with multiple GF-PUSCHs, the method 1100 further includes: and the network equipment sends second indication information to the terminal equipment, wherein the second indication information is used for indicating a target GF-PUSCH which can be used for the terminal equipment to send UCI to the network equipment in the plurality of GF-PUSCHs.
It should be understood that the second indication information may be carried in RRC signaling or DCI sent by the network device to the terminal device, and therefore, the second indication information may be represented by adding a new field in the RRC signaling or DCI.
The method for transmitting uplink control information according to the embodiment of the present application is described in detail above with reference to fig. 1 to 11, and the terminal device and the network device according to the embodiment of the present application are described below with reference to fig. 12 to 15. It should be understood that the terminal devices in fig. 12-15 correspond to the method 200 described above, and the network devices in fig. 12-15 correspond to the method 1100 described above. The terminal device and the network device in fig. 12-15 may perform the above-described methods 200 and 1100, respectively. For the sake of brevity, duplicate descriptions are appropriately omitted below.
