The embodiment of the invention provides an uplink transmission method and device, which are used for solving the problem of poor uplink transmission performance in the prior art.
The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.
Referring to fig. 2, an uplink transmission method according to an embodiment is provided, which may be performed by a terminal device, and the method includes:
step 201: in case there is a time domain resource overlap of a first physical uplink control channel PUCCH carrying first uplink control information UCI having a first priority and second UCI having a second priority with the second uplink channel, performing any one of the following:
Uplink transmission is carried out according to whether the second uplink channel or one target uplink channel in the second uplink channel supports multiplexing with different priorities;
and respectively determining a first target PUSCH used for bearing the first UCI and a second target PUSCH used for bearing the second UCI in the second uplink channel under the condition that the second uplink channel is a plurality of Physical Uplink Shared Channels (PUSCHs).
It should be noted that, the second uplink channel may include at least one of a PUSCCH and a PUSCH, and on the terminal device side, the transmission may be a transmission, and on the network device side (e.g., the base station side), the transmission may be a reception, and the resource overlapping may be understood that there is a collision.
In the uplink transmission method of the present embodiment, in the case where PUCCHs carrying UCI of different priorities collide with the second uplink channel, uplink transmission may be performed according to whether the second uplink channel supports multiplexing of different priorities or according to whether one target uplink channel in the second uplink channel supports multiplexing of different priorities, or in the case where PUCCHs carrying UCI of different priorities collide with the second uplink channel and the second uplink channel collides with multiple PUSCHs, target PUSCHs for carrying UCI of different priorities may be determined respectively in the collided PUSCHs. That is, in case that there is a collision between the PUCCH carrying UCI having different priorities and the second uplink channel, according to the second uplink channel or the determined result of whether the target channel supports multiplexing of different priorities, it is determined how to resolve the collision, or the PUSCH carrying UCI of different priorities is determined in the second uplink channel, respectively, so as to implement multiplexing transmission of UCI of different priorities, respectively, to ensure normal uplink transmission and improve uplink transmission performance.
In one embodiment, the uplink transmission is performed according to whether the second uplink channel or a target uplink channel in the second uplink channel supports multiplexing with different priorities, including one of the following:
if the second uplink channel is the second PUCCH, uplink transmission is carried out according to whether the second uplink channel supports multiplexing with different priorities; or (b)
And if the second uplink channel is the PUSCH, carrying out uplink transmission according to whether one target PUSCH in the second uplink channel supports multiplexing with different priorities.
That is, in the case that the second uplink channel is the PUCCH, uplink transmission may be performed according to whether the second PUCCH supports multiplexing with different priorities, so as to improve uplink transmission performance. In the case that the second uplink channel is a PUSCH, uplink transmission may be performed according to whether one target PUSCH in the second uplink channel supports multiplexing with different priorities, so as to improve performance of uplink transmission.
That is, in this embodiment, in the case that PUCCHs carrying UCI with different priorities collide with the second PUCCH, uplink transmission may be performed according to whether the second PUCCH supports multiplexing with different priorities, and in the case that PUCCHs carrying UCI with different priorities collide with the PUSCH, uplink transmission may be performed according to whether one target PUSCH of the PUSCH supports multiplexing with different priorities, so as to improve performance of uplink transmission.
In one embodiment, in the case that the second uplink channel is the second PUCCH, uplink transmission is performed according to whether the second uplink channel supports multiplexing with different priorities, including one of the following:
multiplexing transmission is carried out on the first PUCCH and the second PUCCH under the condition that the second PUCCH supports multiplexing of different priorities; or (b)
And under the condition that the second PUCCH does not support multiplexing of different priorities, discarding the second UCI in the first PUCCH if the second PUCCH corresponds to the first priority, multiplexing the first UCI in the first PUCCH and the second PUCCH for transmission, and/or discarding the second PUCCH if the second PUCCH corresponds to the second priority.
Discarding indicates that transmission is not needed, and UCI carried on PUCCH is discarded accordingly.
That is, in this embodiment, when the second PUCCH supports multiplexing with different priorities, multiplexing transmission may be performed on the first PUCCH and the second PUCCH according to a predetermined multiplexing rule, that is, one PUCCH resource is determined, which is used to simultaneously carry the first UCI and the second UCI on the first PUCCH and the UCI on the second PUCCH. According to a predetermined multiplexing rule, it may be that all UCI in the first UCI and the second UCI may be put on one uplink channel resource for simultaneous transmission, or that a part of UCI is discarded because of limited bearing capacity of the PUCCH resource, which is a category of multiplexing transmission, and similar explanation is omitted below.
Under the condition that the second PUCCH does not support multiplexing of different priorities, if the second PUCCH corresponds to the first priority, discarding the second UCI in the first PUCCH, and carrying out multiplexing transmission on the first UCI in the first PUCCH and the second PUCCH according to a preset multiplexing rule, namely determining a PUCCH resource for simultaneously carrying the first UCI on the first PUCCH and the UCI on the second PUCCH;
and if the second PUCCH corresponds to the second priority, discarding the second PUCCH so as to avoid the conflict between the second PUCCH and the first PUCCH and improve the transmission stability.
In an embodiment, in the case that the second uplink channel is a PUSCH, uplink transmission is performed according to whether one target PUSCH in the second uplink channel supports multiplexing with different priorities, including one of the following:
multiplexing and transmitting the first PUCCH and the target PUSCH under the condition that the target PUSCH supports multiplexing of different priorities; or (b)
Under the condition that the target PUSCH does not support multiplexing of different priorities, if the target PUSCH corresponds to the first priority, discarding the second UCI in the first PUCCH, and multiplexing the first UCI in the first PUCCH and the target PUSCH for transmission, and/or if the target PUSCH corresponds to the second priority, executing the following steps:
Discarding the target PUSCH;
after discarding the target PUSCH, if there is an overlap between the other PUSCHs and the first PUCCH in the time domain in the second uplink channel, discarding the other PUSCHs, or selecting one PUSCH from the other PUSCHs as the target PUSCH, and repeatedly executing uplink transmission according to whether one target PUSCH in the second uplink channel supports multiplexing with different priorities until there is no overlap between the time domain resources of the first PDCCH and the PUSCH.
In the case that the second uplink channel is a PUSCH, uplink transmission may be performed according to whether one target PUSCH in the second uplink channel supports multiplexing with different priorities, where it should be noted that the target PUSCH may be a PUSCH selected to carry UCI on the first PUCCH according to a predetermined PUSCH selection rule.
Under the condition that the target PUSCH supports multiplexing of different priorities, multiplexing transmission is carried out on the first PUCCH and the target PUSCH according to a preset multiplexing rule, namely, a first UCI and a second UCI or parts thereof (which can be parts in the first UCI, the second UCI or parts in the whole of the first UCI and the second UCI) on the first PUCCH are transferred to the target PUSCH for uplink transmission; specifically, whether all UCI is transferred or not, part of UCI is discarded, and the UCI is determined according to a predetermined multiplexing rule; for example, if UCI carried on PUCCH contains HARQ-ACK and CSI and there is no CSI on target PUSCH, then all UCI carried on PUCCH, i.e. HARQ-ACK and CSI, may be transferred to PUSCH for transmission without transmitting PUCCH, whereas if CSI is not present on PUSCH, since CSI is already present and CSI on PUCCH is no longer required to be transmitted, only part of UCI on PUCCH, i.e. HARQ-ACK, is transferred to target PUSCH for transmission, CSI is discarded with PUCCH; for another example, if UCI carried on PUCCH contains HARQ-ACK and SR, since SR cannot be transmitted on PUSCH, only part of UCI carried on PUCCH, i.e. HARQ-ACK, is transferred to PUSCH for transmission, SR is discarded as PUCCH.
Under the condition that the target PUSCH does not support multiplexing of different priorities, if the target PUSCH corresponds to the first priority, discarding the second UCI in the first PUCCH, and multiplexing the first UCI in the first PUCCH with the target PUSCH according to a preset multiplexing rule, namely transferring the first UCI on the first PUCCH into the target PUSCH for uplink transmission; if the target PUSCH corresponds to the second priority, discarding the target PUSCH, and further, if there is another PUSCH (PUSCH remaining except the discarded PUSCH in the second uplink channel) overlapping with the first PUCCH in the time domain, discarding the other PUSCHs or selecting one target PUSCH from the other PUSCHs, that is, updating the target PUSCH, repeating the above steps, that is, restarting the step of uplink transmission according to whether the target PUSCH supports multiplexing with different high priorities, until there is no overlapping of time domain resources of the first PUCCH and the PUSCH (that is, no collision), so that the performance of uplink transmission can be improved.

The following describes the procedure of the above method in specific embodiments, taking a network device as an example of a base station.
Currently, in 5G NR (5 Generation New RAT, fifth generation new wireless system) Rel-17, in order to avoid the problem of discarding downlink retransmissions caused by HARQ-ACKs carried on channels with low priority, multiplexing transmission between HARQ-ACKs with low priority and HARQ-ACKs with high priority can be supported. When there is time domain resource overlapping (i.e., collision) uplink channels including uplink channels with different priorities, a possible implementation manner is to process collisions between uplink channels with the same priority first, and then process collisions of uplink channels with different priorities. When a collision of uplink channels with different priorities is handled, a new PUCCH resource carrying UCI with high priority and low priority obtained by PUCCH multiplexing with different priorities may appear, further overlaps with another PUCCH or further overlaps with PUSCH, and at this time, there is no method how to transmit considering that PUCCH or PUSCH overlapping with the new PUCCH resource may not support multiplexing with different priorities.

(1) UCI transmission in 5G NR:
the UCI includes information such as HARQ-ACK, CSI, SR, etc. UCI is transmitted on PUCCH. The HARQ-ACK is a generic term of ACK and NACK, and is used for feeding back a PDSCH or a PDCCH (e.g., a PDCCH (also called SPS PDSCH release) indicating SPS resource release, a PDCCH indicating SCell redundancy) that needs HARQ-ACK feedback, to inform a base station whether the PDSCH or the PDCCH that needs HARQ-ACK feedback is received correctly; the CSI is used for feeding back the channel quality of downlink transmission, so that the base station is helped to better perform downlink scheduling, such as MCS selection, configuration of proper RB resources and the like according to the CSI; the SR is used for requesting allocation of PUSCH transmission resources to the base station for uplink traffic transmission when the terminal device has uplink traffic to be transmitted.
The HARQ-ACK may be fed back based on different time units, which may be slots (slots) or sub-slots (sub-slots). A sub-slot is a fixed division of a slot into a plurality of sub-units according to a predetermined sub-slot length, for example, a sub-slot length of 7 symbols, a slot containing 14 symbols may be divided into 2 sub-slots, and for example, a sub-slot length of 2 symbols, a slot containing 14 symbols may be divided into 7 sub-slots. When feedback is performed based on the time slot, determining the time slot where the PUCCH carrying the HARQ-ACK is located according to a feedback time sequence n+k1, wherein n is a reference uplink time slot corresponding to the time slot where the downlink transmission (comprising the PDSCH and the PDCCH requiring the HARQ-ACK feedback) requiring the HARQ-ACK feedback is located, and k1 is a time slot offset value (namely, the unit of k1 is the time slot) between the reference uplink time slot and the target time slot where the HARQ-ACK is transmitted; when feedback is performed based on the sub-slots, determining the sub-slot where the PUCCH carrying the HARQ-ACK is located according to a feedback time sequence n+k1, wherein n is a reference uplink sub-slot corresponding to the time slot where the downlink transmission (comprising the PDSCH and the PDCCH requiring the HARQ-ACK feedback) requiring the HARQ-ACK feedback is located, and k1 is a sub-slot offset value (namely, k1 is a sub-slot unit) between the reference uplink sub-slot and the target sub-slot where the HARQ-ACK is transmitted. The PUCCH resources carrying HARQ-ACKs do not cross the time units used for HARQ-ACK feedback, i.e. if based on sub-slot transmission, the PUCCH carrying HARQ-ACKs does not exceed the sub-slot boundary, i.e. do not cross transmission in multiple sub-slots.
(2) PUCCH and PUCCH/PUSCH overlap of the same priority
The parallel transmission of the PUCCH and the PUSCH at the same time is not supported in NR Rel-16, whether on the same carrier or different carriers. When there is an overlap in time domain resources between PUCCH and PUSCH (general PUCCH and PUSCH refer to PUCCH and PUSCH without repeated transmission, unless otherwise specified), UCI (generally HARQ-ACK and CSI) may be transferred from PUCCH to PUSCH for transmission if a predetermined time line (timeline) is satisfied, SR is not transmitted on PUSCH if SR is present, and SR is discarded. If there are a plurality of PUSCHs overlapping the PUCCH, one PUSCH is selected according to a rule.
Wherein, the definition of timeline is: if the PUCCH or PUSCH has a corresponding PDCCH, for example, the HARQ-ACK carried by the PUCCH is the HARQ-ACK of the PDSCH having the PDCCH schedule or the HARQ-ACK of the PDCCH indicating the release of the downlink SPS resource, the PDCCH of the schedule PDSCH or the PDCCH indicating the release of the downlink SPS resource is the PDCCH corresponding to the PUCCH, or may also be referred to as the PDCCH of the schedule PUCCH, the PDCCH of the schedule PUSCH is the PDCCH corresponding to the PUSCH, the first symbol of the channel with the earliest start time in the overlapped PUCCH and PUSCH is taken as the target symbol, if there are multiple channels with the same start time, one channel is selected at will, the first symbol is taken as the target symbol, and the target symbol needs to satisfy the following timeline to perform multiplexing transmission, otherwise, the channel is considered as error scheduling:
Timeline1: the target symbol is not earlier than the first symbol (including CP) after the T1mux time after the last symbol of any one PDSCH or SPS PDSCH release requiring HARQ-ACK feedback on PUCCH, i.e. the time interval between the target symbol and the last symbol of any one PDSCH or SPS PDSCH release described above is not less than the T1mux time. T1mux is related to the processing delay of PDSCH, and can be calculated according to a predetermined formula and related parameters. The purpose of this timeline is to ensure that the acquisition and preparation of the HARQ-ACK can be completed before the transmission of the finally determined channel for transmitting the HARQ-ACK begins.
Timeline2: the target symbol is not earlier than the first symbol (including CP) after the T2mux time after the last symbol of either PDCCH (including PDCCH requiring HARQ-ACK feedback) scheduling PDSCH (if any) and PUSCH (if any), i.e., the time interval between the target symbol and the last symbol of either of the above PDCCHs is not less than the T2mux time. The T2mux is related to the processing delay of the PUSCH and can be calculated according to a predetermined formula and related parameters. The purpose of the timer is to ensure that when UCI needs to be transferred to PUSCH for transmission, a PDCCH for scheduling PUSCH can be obtained before PUCCH starts to be prepared, so that UCI transmission does not need to be prepared on PUCCH, and transmission preparation including UCI can be completed before PUSCH transmission, that is, UCI acquisition and multiplexing processing are completed, and TB preparation (such as operations of coding, modulation, scrambling, etc.) is completed; this T2mux is used to simulate the CSI and the preparation time for SR multiplexing with HARQ-ACK if it is multiplexing between multiple PUCCHs.
If the HARQ-ACK carried by the PUCCH has no corresponding PDCCH (i.e. the HARQ-ACK is the HARQ-ACK of the SPS PDSCH), there is no PDCCH for scheduling the PDSCH at this time, and if there is no PUSCH or no corresponding PDCCH, only the check T1mux is needed and the check T2mux is not needed. If CSI and/or SR are carried on PUCCH, then check T1mux is not needed because there is no corresponding PDSCH, and further if there is no PUSCH or PUSCH there is no corresponding PDCCH, then check T2mux is also not needed.
If at least one PUCCH is repeatedly transmitted (i.e. UCI is repeatedly transmitted in each slot, which occupies a plurality of slots, also called multislot transmission) when PUCCH and PUCCH overlap, then only for overlapping repetition, the low priority processing is discarded according to the transmission high priority, without affecting the absence of overlapping repetition. If the PUCCH and the repeatedly transmitted PUSCH overlap, when the PUSCH adopts the time slot-based repeated transmission (R15 repeated transmission or R16 repetition type A), UCI carried by the PUCCH is transferred to one or more PUSCH time slots overlapping with the PUCCH for transmission; when PUSCH uses R16 repetition type B, UCI carried by PUCCH is transferred to actual repetition PUSCH, which is overlapped with PUCCH and contains more than 1 symbol, for transmission (actual repetition is repetition PUSCH obtained after segmentation according to unavailable symbols, DL symbols, slot boundaries, etc.); the PUSCH of the above repetition or repetition overlapping with the PUCCH is required to satisfy multiplexing timing. If the PUCCH using the repeated transmission overlaps with the PUSCH using or not using the repeated transmission, the PUSCH overlapping with the PUCCH is discarded, so that the repeated transmission of the PUCCH is not interrupted.
The parallel transmission of PUCCH and PUSCH on different carriers in the case of inter-band (inter-band transition) CA (carrier aggregation) can be supported in R17 according to the UE capability, but the parallel transmission is temporarily not supported on the same carrier and in the case of intra-band (inter-band transition) CA.
(3) Channel transmission with different physical layer priorities
One UE may support different traffic types, such as an eMBB traffic and a URLLC traffic. The requirements of different traffic types for reliability and transmission delay are different. The URLLC traffic flow may occur sporadically, so different system resources are reserved independently for different traffic, the overhead on the system resources is relatively large, and the resources reserved for the URLLC may not be used in many cases. In order to improve the utilization rate of system resources, different services can be supported to multiplex transmission on the same resources. To avoid the interaction between services, different priorities may be defined for different services, so as to distinguish which channels and information are more important when resource conflicts occur.
The physical layer priority of PUCCH, PUSCH may be obtained by default, DCI dynamic indication, or RRC semi-static configuration. For example, when the PUCCH carries an SR, its priority is determined by the priority corresponding to the SR it carries, and the priority corresponding to each SR configuration is configured by higher layer signaling; when the PUCCH carries the HARQ-ACK of the SPS PDSCH or the HARQ-ACK of the PDCCH (namely SPS PDSCH release) indicating the SPS resource release, the priority is determined by the number of the HARQ-ACK codebook configured for the SPS PDSCH through a high-layer signaling, the HARQ-ACK codebook corresponding to the number 0 is low priority, and the HARQ-ACK codebook corresponding to the number 1 is high priority; the PUCCH defaults to low priority when carrying CSI (including periodic CSI and SP-CSI). When the DCI includes a priority indication field, the priority may be obtained through the priority indication field in the DCI corresponding to the PUCCH and PUSCH (or PDCCH, where PDCCH and DCI may be considered equivalent in the present invention, and DCI is a specific format used for PDCCH transmission, and having the corresponding DCI is equivalent to having the corresponding PDCCH), that is, a dynamic priority indication manner, for example, when PDCCH schedules one PDSCH, the priority of PUCCH carrying HARQ-ACK of the PDSCH may be indicated through the priority indication field; when the PDCCH schedules one PUSCH, the priority of the scheduled PUSCH can be indicated through a priority indication field, wherein the PUSCH comprises a PUSCH only carrying a TB or a PUSCH only carrying A-CSI or a PUSCH simultaneously carrying the TB and the A-CSI; for PUSCH carrying SP-CSI, its priority may be obtained by activating the priority indication field in DCI of PUSCH carrying SP-CSI. If no priority indication field is included in the DCI or no priority is configured for higher layer signaling, the default is low priority.
The implementation complexity is taken into account in Rel-16, and multiplexing transmission between channels with different physical layer priorities is not supported. When channels with different physical layer priorities collide, that is, a plurality of PUCCHs overlap in time domain on the same carrier, or a plurality of PUCCHs overlap in time domain on the same carrier or different carriers, or a plurality of PUSCHs overlap in time domain on the same carrier, the channels with low priority are discarded, and only the channels with high priority are transmitted. Considering that stopping the transmission of a low priority channel based on the comparison of priorities requires a certain additional processing time, the timeline for stopping the low priority channel is further defined: the time interval between the PDCCH corresponding to the high priority channel and the start symbol of the high priority channel is required to be not less than a predetermined T time in which the original processing delay (e.g., T1 trace, T2 trace) and the time (d 1) required for stopping are taken into consideration.
In Rel-17, considering the influence of system efficiency degradation caused by always discarding low priority channels, for example, always discarding low priority HARQ-ACKs, which may cause the downlink transmission corresponding to the low priority HARQ-ACKs to perform redundant retransmission because feedback information cannot be timely obtained, and considering supporting multiplexing transmission between uplink channels with different physical layer priorities. It has been supported at present that when there is an overlap between an uplink channel carrying a low priority HARQ-ACK and an uplink channel carrying a high priority HARQ-ACK on time domain resources, the low priority HARQ-ACK and the high priority HARQ-ACK can be placed on the same uplink channel for transmission according to a specific rule without discarding the low priority HARQ-ACK. When there are collisions between a plurality of uplink channels having different priorities, in R17, channels having different priorities are supported for multiplexing transmission, however, when a collision of PUCCHs having different priorities is handled, a new PUCCH resource carrying UCI of high priority and low priority may be obtained, and this PUCCH resource may further overlap another PUCCH or further overlap PUSCH, and at this time, if the PUCCH or PUSCH overlapping the new PUCCH resource does not support multiplexing of different priorities, there is no method how to transmit. Based on the above, the invention provides an uplink transmission method to improve uplink transmission performance.
Example 1 (overlap between PUCCHs): as shown in fig. 4, in the overlapping situation, LP represents a low priority, HP represents a high priority, AN is AN abbreviation of HARQ-ACK, and a first PUCCH is a HP an+lp AN, that is, a PUCCH carrying both HP AN and LP AN, where HP AN is a first UCI, LP AN is a second UCI, the first priority is HP, the second priority is LP, and the second uplink channel is a second PUCCH, that is, AN HP PUCCH carrying HP SR (Scheduling Request ).
Terminal equipment side: the decision is made according to whether the HP SR (second PUCCH) supports multiplexing with different priorities, if not, then, because there is AN LP AN in the first PUCCH, and when multiplexing with the HP SR is not supported at this time, it is determined to discard the LP AN, and multiplex on the same channel in a multiplexing manner with the same priority, that is, it is determined that one PUCCH resource is used to carry the HP AN and the HP SR simultaneously, and the HP AN and the HP SR are simultaneously transmitted on this resource (where the HP SR may be a display transmission, for example, the SR information is represented by X bits and encoded together with the AN, or may be AN implicit transmission, for example, by selecting a specific resource or a specific cyclic shift to simultaneously express that there is a positive SR), as shown in fig. 5. If so, all UCI on the first PUCCH and the second PUCCH are directly multiplexed for transmission, that is, one PUCCH resource is determined to be used for carrying the HP AN, the LP AN and the HP SR at the same time, and the HP AN, the LP AN and the HP SR are transmitted at the same time on this resource (the transmission manner of the HP SR is the same and will not be repeated), as shown in fig. 6.
Base station side: a PUCCH resource is determined in the same manner as the terminal device side, and a corresponding UCI combination is received on this PUCCH resource.
It should be noted that, in the above embodiment 1, the first PUCCH is a PUCCH carrying HP AN/HP sr+lp SR/LP CSI (assuming that HP AN/HP SR is supported and multiplexing transmission with LP SR/LP CSI, "/" indicates and/or), and the second PUCCH is a PUCCH carrying HP SR, and the above manner is equally applicable; the first PUCCH is a PUCCH bearing HP AN+LP AN, the second PUCCH is a PUCCH bearing LP SR/LP CSI, and the method is applicable; the first PUCCH is a PUCCH carrying HP sr+lp SR/LP CSI (assuming that multiplexing transmission of HP AN and LP SR/LP CSI is supported, "/" indicates and/or), and the second PUCCH is a PUCCH carrying HP SR/HP AN, the same applies; if a conflict can occur in supporting multiple ANs with the same priority, the first PUCCH is a PUCCH carrying HP AN/HP SR+LP AN/LP SR/LP CSI, the second PUCCH is a PUCCH carrying LP AN, or a combination PUCCH of LP AN and LP SR/LP CSI, the method is applicable in the same way, or the first PUCCH is a PUCCH carrying HP AN/HP SR+LP AN/LP SR/LP CSI, the second PUCCH is a PUCCH carrying HP AN/HP SR, and the method is applicable in the same way.
Embodiment 2 (overlap between PUCCH and PUSCH): as shown in fig. 7, in the overlapping case, the first PUCCH is a PUCCH carrying HP AN and LP AN, and the second uplink channel is a PUSCH; the other description is the same as in example 1.
Terminal equipment side: firstly, determining a target PUSCH, and if only one PUSCH overlaps with the PUCCH, determining the PUSCH as the target PUSCH; if there are multiple PUSCHs overlapping with PUCCHs, a target PUSCH is determined according to a predetermined PUSCH selection rule, for example, if both PUSCHs do not carry a-CSI and both have PDCCHs, then LP PUSCH1 is selected as the target PUSCH according to a carrier number minimum principle, and if, for example, a high priority is selected according to a priority, then it is selected from HP PUSCH3 and HP PUSCH4, if both PUSCHs do not carry a-CSI and both have PDCCHs, then HP PUSCH3 is selected as the target PUSCH according to a carrier number minimum principle, and then the target PUSCH is determined in other selection manners is not excluded.
And determining how to transmit according to whether the target PUSCH supports multiplexing of different priorities: when the support is determined, the HP AN and the LP AN on the first PUCCH are transferred to a target PUSCH for transmission; as shown in fig. 8 (taking the selected target PUSCH as HP PUSCH3 as an example); the HP AN and the LP AN can be independently coded or jointly coded on the PUSCH, if the HP AN and the LP AN are jointly coded, the transmission method of the AN on the PUSCH in the prior art is reused, if the HP AN and the LP AN are independently coded, the HP AN works according to the transmission mode of the AN on the PUSCH in the prior art, and the LP AN works according to the transmission mode of the CSI part1 in the prior art; if the higher layer signaling configures a resource offset parameter (beta-offset) of the AN for different priorities for the PUSCH, calculating AN AN resource by using the resource offset parameter corresponding to the HP AN, calculating AN AN resource by using the resource offset parameter corresponding to the LP AN, and if only one resource offset parameter is configured for one UCI, not distinguishing the priorities, calculating resources by using the same resource offset parameter corresponding to the AN by using the HP AN and the LP AN, or calculating resources by using the resource offset parameter corresponding to the AN by using the resource offset parameter corresponding to the CSI part1 by using the LP AN; if the target PUSCH is LP if it is determined that the target PUSCH is not supported, discarding the PUSCH and further discarding other PUSCHs overlapping the PUCCH, as in the first mode of fig. 9, or repeating the steps of determining the target PUSCH and determining for other PUSCHs until the overlap of the PUCCH and PUSCH is resolved, as in the second mode of fig. 9 (assuming that the HP PUSCH3 is determined to be the target PUSCH after iterative selection and the PUSCH3 supports different priority multiplexing); if the target PUSCH is HP, then LP on the first PUCCH is dropped, i.e. LP AN is dropped, and HP AN is transferred to the target PUSCH for transmission, as shown in fig. 10.
Base station side: determining a PUCCH resource in the same mode as the terminal equipment side, and receiving a corresponding UCI combination on the PUCCH resource;
it should be noted that, for embodiment 2, the PUCCH carrying HP AN and LP AN is replaced by a PUCCH carrying other HP and LP UCI combination, and the same applies to the above method.
Example 3 (method 2): as shown in fig. 7, other explanations are the same as those of embodiments 1 and 2.
The method adopts the following mode 1:
terminal equipment side: dividing the PUSCH into two sets according to the priority, wherein the first PUSCH set is an HP PUSCH3 and an HP PUSCH4, and the second PUSCH set is an LP PUSCH1 and an LP PUSCH2; then, determining a target PUSCH in the first PUSCH set and the second PUSCH set according to a preset PUSCH selection rule; assuming that none of these PUSCHs carries a-CSI and has PDCCH, according to the carrier number minimization principle, HP PUSCH3 is selected in the first PUSCH set for carrying HP AN on PUCCH, LP PUSCH1 is selected in the second PUSCH set for carrying LP AN on PUCCH, i.e. UE transfers HP AN on PUCCH to HP PUSCH3 for transmission, sends HP PUSCH3 carrying HP AN, transfers LP AN to LP PUSCH1 for transmission, sends LP PUSCH1 carrying LP AN, and discards PUCCH, other PUSCHs may be normally sent, as shown in fig. 11.
Base station side: the method comprises the steps of adopting the same mode as a terminal equipment side to receive HP PUSCH3 carrying HP AN, obtaining HP AN from the HP PUSCH3, receiving LP PUSCH1 carrying LP AN from the HP PUSCH1, obtaining LP AN from the LP AN, and receiving other PUSCHs on other carriers without receiving PUCCH;
adopts the mode 2:
terminal equipment side: according to a PUSCH selection rule in the 4 PUSCHs, firstly selecting one PUSCH as a first target PUSCH carrying the HP AN, and then selecting one PUSCH from the rest PUSCHs as a second target PUSCH carrying the LP AN; assuming that the PUSCH selection rule is to preferentially select PUSCHs having the same priority as UCI to be carried, and that none of the PUSCHs carries a-CSI and has PDCCH in a plurality of PUSCHs having the same priority, selecting according to the carrier number minimum rule, selecting from HP PUSCHs 3 and 4 for HP AN to determine HP PUSCH3 as a first target PUSCH, selecting from LP PUSCHs 1 and 2 for LP AN to determine LP PUSCH1 as a second target PUSCH; namely, the UE transfers the HP AN on the PUCCH to the HP PUSCH3 for transmission, sends the HP PUSCH3 carrying the HP AN, transfers the LP AN to the LP PUSCH1 for transmission, sends the LP PUSCH1 carrying the LP AN, and discards the PUCCH, and other PUSCHs can be normally sent, as shown in fig. 11.
Base station side: determining a final transmission result in the same way as the terminal equipment side, and performing corresponding receiving;
the method adopts the following mode 3:
terminal equipment side: assuming that LP PUSCH1 supports different priority multiplexing, LP PUSCH2 does not support different priority multiplexing, HP PUSCH3 does not support different priority multiplexing, and HP PUSCH4 supports different priority multiplexing, when PUSCH grouping is performed, LP PUSCH1 and HP PUSCHs 3 and 4 are used as a fourth PUSCH set, and HP PUSCH4 and LP PUSCHs 1 and 2 are used as a fifth PUSCH set; respectively determining target PUSCHs in two PUSCH sets, and determining LP PUSCH1 as a first target PUSCH according to a carrier number minimum principle if the target PUSCHs are determined without considering priority and do not bear A-CSI and have PDCCHs, and determining LP PUSCH2 bits of a second target PUSCH according to a selection rule after removing the LP PUSCH1 in a fifth set because the LP PUSCH1 is also contained in the fifth set; namely, the UE transfers the HP AN on the PUCCH to the LP PUSCH1 for transmission, sends the LP PUSCH1 carrying the HP AN, transfers the LP AN to the LP PUSCH2 for transmission, sends the LP PUSCH2 carrying the LP AN, and discards the PUCCH, and other PUSCHs can be normally sent, as shown in fig. 12.
Base station side: determining a final transmission result in the same way as the terminal equipment side, and performing corresponding receiving;
it should be noted that, for embodiment 3, the PUCCH carrying HP AN and LP AN is replaced by a PUCCH carrying other HP and LP UCI combination, and the same applies to the above method.
