Description

Method and equipment for determining uplink information transmission channel
Technical Field
The present application relates to the field of mobile communications technologies, and in particular, to a method and a device for determining an uplink information transmission channel.
Background
In the NR system, a terminal device transmits Uplink Control Information (UCI) in a Physical Uplink Control Channel (PUCCH), and if the terminal device is scheduled to transmit a Physical Uplink Shared Channel (PUSCH) at the same time, the power efficiency of the terminal device is low. Intermodulation interference may also be generated if the PUCCH and PUSCH are relatively far apart in frequency. Thus, the terminal device may not support simultaneous transmission of PUCCH and PUSCH channels.
For example, when the PUCCH for carrying UCI and at least one PUSCH overlap in time in the same slot, the mobile terminal device multiplexes the UCI in the slot onto one PUSCH (i.e., the "target channel").
In view of the burstiness of URLLC service data, in order to improve the utilization rate of system resources, the base station usually does not reserve resources for URLLC service transmission, but adopts a preemption mode. If the time resources of the PUCCH and the PUSCHs of the terminal equipment are overlapped, and the terminal equipment does not support the simultaneous transmission of the PUCCH and the PUSCH channels, the terminal equipment determines a target channel in the PUSCHs to be used for carrying UCI information corresponding to the PUCCH. If the target channel is preempted, it means that the resource of the coded modulation symbol occupied by the UCI information in the target channel may also be preempted, resulting in that the UCI cannot be transmitted to the network device side, which results in a decrease in system efficiency. Especially if HARQ-ACK information is included in the UCI, the network device will have to retransmit all PDSCHs related to HARQ-ACK, resulting in system inefficiency.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the target time unit, if the terminal device determines, in a plurality of PUSCHs, that the first target channel is used for carrying UCI information corresponding to the PUCCH, but the first target channel is preempted in the transmission process, the resource of the coded modulation symbol occupied by the UCI information in the first target channel is preempted. In this case, other channels may be used to carry UCI information that cannot be normally transmitted due to channel preemption in the target time unit. Therefore, the second target channel for carrying the UCI can be determined among other channels except the first target channel. Similarly, if the second target channel is also preempted, a third target channel is determined … … within the target time unit
Under the condition that a channel used for bearing the UCI in the target time unit is preempted, another channel is determined again to bear the UCI, so that the problems that the UCI cannot be normally sent and the system efficiency is low due to channel preemption can be solved.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of the positions of PUCCH and PUSCH groups in slot n.
If the terminal equipment sends PUSCHs (such as PUSCH-1, PUSCH-2, PUSCH-3 and PUSCH-4 in a plurality of service cells of the Slot n), the terminal equipment is called a PUSCH group. In the figure, some or all of DCI (DCI-1, DCI-2, DCI-3, DCI-4) scheduling a PUSCH group and DCI (DCI-0) scheduling a PDSCH to feed HARQ-ACK back in the same time unit are included. The arrows in fig. 1 drawn by DCI-x indicate the scheduling relationship. If the resources of the PUSCH group and the PUCCH to carry the HARQ-ACK are overlapped in time, the terminal equipment multiplexes the UCI in the Slot n to one PUSCH in the PUSCH group under the condition of meeting 9.2.5 in 3GPP TS 38.213V15.6.0, and the PUSCH is called as a target channel. The target channel is the smallest corresponding serving Cell index (ServCellIndex) in the PUSCH group (PUSCH in Cell index 2 in the figure). If there are a plurality of PUSCHs (PUSCH-1 and PUSCH-2) located at the smallest serving cell index number in the PUSCH group, the target channel is the PUSCH (PUSCH-1) transmitted earliest among the plurality of PUSCHs located at the smallest serving cell index number in the PUSCH group.
Fig. 2 is a schematic diagram illustrating that the uplink channel of the terminal is preempted.
Because the data volume of the eMBB service is large and the transmission rate is high, a long time domain scheduling unit is usually adopted for data transmission to improve the transmission efficiency. The generation of data packets of URLLC traffic is bursty and random, and may not generate data packets for a long time or may generate multiple data packets for a short time. The data packets of URLLC traffic are in most cases small packets. If a base station (network equipment) allocates resources for the URLLC service in a resource reservation manner, system resources are wasted when there is no URLLC service data, and the short delay characteristic of the URLLC service requires that a data packet is transmitted in a very short time, so the base station needs to reserve a sufficiently large bandwidth for the URLLC service, resulting in a severe decrease in the utilization rate of system resources. In view of the burstiness of URLLC service data, in order to improve the utilization rate of system resources, the base station usually does not reserve resources for URLLC service transmission, but adopts a preemption mode. As shown in fig. 2, the terminal device 1 acquires scheduling information indicating its transmission target channel. In addition, terminal device 1 acquires a PDCCH including a "preemption indication" that may be used by terminal device 1 to determine that a "victim resource" of a target channel is preempted.
FIG. 3 is a flow chart of an embodiment of the method of the present invention.
The embodiment of the application provides a method for determining an uplink information transmission channel, which comprises the following steps of 101-103:
step 101, determining a first target channel in the first PUSCH group, for carrying the target UCI, and discarding the PUCCH;
wherein the resources of each PUSCH and PUCCH in the first PUSCH group are within the same time unit (e.g., the "target time unit" referred to herein); the PUCCH contains a target UCI; preferably, the time unit is a time slot or a sub-time slot.
Preferably, the first target channel is the smallest index number of the corresponding serving cell in the first PUSCH group; further, the first target channel is the earliest transmission time among the plurality of PUSCHs with the smallest serving cell index numbers in the first PUSCH group.
Taking the situation of fig. 1 as an example, the target time unit is Slot n. In the target time unit, according to the mode described in chapter 9 of 3GPP TS 38.213V15.6.0, the terminal device determines the target channel as the smallest serving Cell index (PUSCH in Cell index 2 in the figure) of the corresponding serving Cell index in the PUSCH group. If there are a plurality of PUSCHs (PUSCH-1 and PUSCH-2) located at the smallest serving cell index number in the PUSCH group, the target channel is the PUSCH (PUSCH-1) transmitted earliest among the plurality of PUSCHs located at the smallest serving cell index number in the PUSCH group, and it is determined that the first target channel is PUSCH-1.
102, the DCI indicates that the first target channel is cancelled;
after the first target channel is determined, the terminal equipment sends the target UCI in the target time unit on the first target channel. If the first target channel is PUSCH, HARQ-ACK is mapped symbol by symbol starting from a symbol after DMRS at PUSCH-1 according to the prior art. On the other hand, the terminal device acquires the information that the first target channel is cancelled again, and after acquiring the cancellation information, the terminal device stops sending the first target channel.
For example, the terminal device should originally transmit the target UCI on PUSCH-1, but receive an indication that PUSCH-1 is cancelled. The terminal equipment stops transmitting the target UCI in PUSCH-1. Part or all of the target UCI may not be sent until the cancellation indication is received, resulting in the network device not being able to acquire the target UCI. In this case, step 103 is optionally performed.
Step 103, determining a second target channel in a second PUSCH group, for carrying the target UCI; the second PUSCH group is a subset of the first PUSCH group, and the starting time of each channel of the second PUSCH group is not earlier than the threshold duration from the time of obtaining the DCI.
Preferably, the threshold duration is not less than T, where T is a processing time from acquiring the DCI to matching the target UCI to a coded modulation symbol in a PUSCH.
That is, the second channel group includes channels in the first PUSCH group whose start time is no earlier than the deadline. The limit point is a time point after the terminal device obtains the time length T from the cancellation indication information. Here, T may be, for example, a minimum time T0 for the terminal device to match the coded output of the target UCI to coded modulation symbols available for UCI in other channels after acquiring the cancellation information.
The second target channel is the smallest corresponding serving cell index number in the second PUSCH group. Further, the second target channel is the PUSCH with the smallest serving cell index number in the second PUSCH group, and the transmission time is the earliest.
Preferably, the first target channel is determined in the first PUSCH group in the same manner as the second target channel is determined in the second PUSCH group.
By the foregoing example, after receiving the downlink control information including the preemption indication, the terminal device cancels PUSCH-1, and needs to multiplex the target UCI to the second target channel, and after receiving the cancellation information, before transmitting the second target channel, to output the UCI in a coded manner and the number Q 'of coded modulation symbols available for UCI in the second target channel'ACKMatching, which requires a certain processing time T. The minimum value of T is different according to the processing capability of the terminal device. The terminal device matches the coded output of the UCI to the minimum length of time in PUSCH of the coded modulation symbols available for UCI, typically reported by the terminal device to the network device. The terminal device matches the coded output of UCI to the PUSCH, while the coded output of UL-SCH data needs to be matched to other resources in the PUSCH than these coded modulation symbols for UCI, so the timing of T0 is also related to the terminal device's coded output matching the UL-SCH. If the first target channel is cancelled, the target UCI is delayed to be sent to other time units, the problem of how to multiplex and jointly encode the target UCI and the UCI in other time units needs to be solved, the system design complexity is high, and the terminal equipment implementation complexity is high. After the first target channel is cancelled, the second target channel is still determined to be used for carrying the target UCI in the original time unit, the terminal equipment can match the coded target UCI to the coded modulation symbol used for UCI mapping in the second target channel, and the coded output of the UL-SCH data is matched to other resources except the coded modulation symbol of the UCI in the second target channel, so that the realization complexity is low.
In this embodiment, a channel with a start time not earlier than an absolute point in the first PUSCH group can be used as a channel in the second channel group, where the absolute point may be a time point after the terminal device obtains the indication T0, and T0 is a minimum time for matching the coded output of the target UCI to a coded modulation symbol available for UCI in another channel after the terminal device obtains the cancellation information. Therefore, the terminal device can determine a second target channel in the second channel group and carry the target UCI, so that the network device can acquire the target UCI in the target time unit, and the influence on the system efficiency is avoided.
It should be noted that, when the network device communicates with a plurality of terminal devices, some terminal devices have strong terminal capabilities and some terminal devices have weak terminal capabilities, that is, T0 in different terminals may be different. Another embodiment may be that the threshold duration T in step 103 is also the maximum value of T0 of multiple terminal devices, which is denoted as T1.
The network equipment (base station) and the terminal equipment may not be of the same vendor, and the base station and the terminal have a uniform knowledge of the starting time of the PUSCH group, which may be established after each terminal equipment reports its own processing capability (T0) to the base station. Therefore, T.gtoreq.T 1 is MAX (T0). Where MAX (T0) represents the maximum value of T0 of the plurality of terminal apparatuses.
Any one embodiment of the method in the first aspect of the present application is applied to a terminal device, and resources of each PUSCH and PUCCH in a first PUSCH group are in the same time unit; the PUCCH comprises a target UCI and comprises the following steps:
step 201, the terminal device determines a first target channel in the first PUSCH group, is configured to carry the target UCI, and discards the PUCCH;
step 202, the terminal device acquires DCI, where the DCI indicates that the first target channel is cancelled;
step 203, the terminal device determines a second target channel in a second PUSCH group, for carrying the target UCI; the second PUSCH group is a subset of the first PUSCH group, and the starting time of each channel of the second PUSCH group is not earlier than the threshold duration from the time of obtaining the DCI.
The features of steps 101-103 are applicable to steps 201-203, and are not described herein.
At this time, the network device cannot acquire the target UCI in the first target channel. However, the terminal device may continue to determine a second target channel in the second channel group within the target time unit and transmit the target UCI on the second target channel.
Any one embodiment of the method of the first aspect of the present application is applied to a network device, and resources of each PUSCH and PUCCH in a first PUSCH group are in the same time unit; the PUCCH comprises a target UCI and comprises the following steps:
step 301, the network device determines a first target channel in the first PUSCH group, receives the target UCI carried in the first target channel, and discards the PUCCH;
step 302, the network device sends DCI, where the DCI indicates that the first target channel is cancelled;
step 303, the network device determines a second target channel in a second PUSCH group, and receives the target UCI carried in the second target channel; the second PUSCH group is a subset of the first PUSCH group, and the starting time of each channel of the second PUSCH group is not earlier than the threshold duration from the time of obtaining the DCI.
The features of steps 101-103 are applicable to steps 301-303, which are not described herein.
Preferably, in any of the foregoing embodiments of the present application, when obtaining the DCI indication, the first target channel has sent part of the target UCI, and the remaining target UCI is sent in the second target channel. As shown in fig. 4(a) to (b). Fig. 4(a) is a schematic diagram illustrating that when the first target channel is cancelled, some target UCI is not transmitted; fig. 4(b) is a diagram illustrating that the target UCI has been transmitted when the first target channel is cancelled. According to different time for acquiring the cancellation information, the UCI information sent by the terminal equipment in the first target channel is different. It is possible that all target UCI have been transmitted when the terminal device cancels the first target channel, as shown in fig. 4 (b). It is also possible that when the terminal device cancels the first target channel, part of the target UCI is not transmitted, as shown in fig. 4 (a). If all the target UCIs are sent completely when the terminal equipment cancels the first target channel, the second target channel does not need to be determined. And if the terminal equipment cancels the first target channel and part of the target UCI is not transmitted, the terminal equipment determines a second target channel and transmits the rest UCI in the second target channel. Alternatively, all of the target UCI is transmitted on the second target channel.
Fig. 5 is a schematic diagram of a first channel group and a first target channel.
The first PUSCH group includes: PUSCH-1, PUSCH-2, PUSCH-3, PUSCH-4, the first target channel is PUSCH-1.
In the figure, the first target channel is PUSCH-1, and the terminal device receives the preemption indication (CI), and is preempted at the "victim resource". A threshold duration (from CI to the limit point) is set since the preemption indication was received.
Fig. 6 is a schematic diagram of switching from a first PUSCH group to a second PUSCH group.
After acquiring the instruction of canceling the PUSCH-1, the terminal equipment stops sending the PUSCH-1, so that the target UCI carried on the PUSCH-1 is not completely sent. In this case, the terminal device determines a second PUSCH group, and the second PUSCH group includes: PUSCH-2 and PUSCH-3. And the terminal equipment determines a second target channel in the second channel group, for example, determines that the PUSCH-2 is the second target channel, and then the terminal equipment transmits the target UCI in the second target channel.
It should be noted that, the present invention does not limit the way in which the terminal device determines the first target channel in the first channel group and determines the second target channel in the second channel group. The smallest index number of the corresponding serving cell, the earliest transmission time, can be determined in a set of PUSCHs as described in the prior art, or can be determined in other manners.
