In the prior art, in the case that uplink channels with different priorities are included in the uplink channels with time-domain resource overlap (that is, conflicts), the current possible processing method is to first deal with the conflicts between uplink channels with the same priority , and then deal with conflicts of uplink channels with different priorities.

Specifically, when dealing with conflicts of uplink channels with different priorities, there will be conflicts between physical uplink control channels (Physical Uplink Control Channel, PUCCH) and physical uplink shared channels (Physical Uplink Shared Channel, PUSCH) with different priorities , and does not support parallel transmission of PUCCH and PUSCH, at this time, there may be cases where some PUSCHs support multiplexing with different priorities, and some PUSCHs do not support multiplexing with different priorities, or whether PUCCH and PUSCH support different priorities The multiplexing configuration is inconsistent.

Therefore, there is no clear method for how to transmit uplink control information (Uplink Control Information, UCI) when PUCCH and PUSCH with different priorities overlap.

In order to better understand the solution provided by the invention, some processes and nouns involved in the solution are described below:

1. Terminal equipment:

The terminal device involved in the embodiment of the present application, the terminal device, may be a device that provides voice and/or data connectivity to users, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal equipment may be different. For example, in a 5G system, the terminal equipment may be called User Equipment (User Equipment, UE). The wireless terminal device can communicate with one or more core networks (Core Network, CN) via the radio access network (Radio Access Network, RAN), and the wireless terminal device can be a mobile terminal device, such as a mobile phone (or called a "cellular "telephones) and computers with mobile terminal equipment, such as portable, pocket, hand-held, computer built-in or vehicle-mounted mobile devices, which exchange language and/or data with the radio access network. For example, Personal Communication Service (PCS) phone, cordless phone, Session Initiated Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant, PDA) and other devices. Wireless terminal equipment can also be called system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point , remote terminal (remote terminal), access terminal (access terminal), user terminal (user terminal), user agent (user agent), and user device (user device), which are not limited in this embodiment of the application.

2. Network equipment:

The network device involved in this embodiment of the present application may be a base station, and the base station may include multiple cells that provide services for terminals. Depending on the specific application, the base station can also be called an access point, or it can be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device can be used to interchange received over-the-air frames with Internet Protocol (IP) packets and act as a router between the wireless terminal device and the rest of the access network, which can include the Internet Protocol (IP) communication network. Network devices may also coordinate attribute management for the air interface. For example, the network equipment involved in the embodiment of the present application may be a network equipment (Base Transceiver Station, BTS) in Global System for Mobile communications (GSM) or Code Division Multiple Access (Code Division Multiple Access, CDMA) ), it can also be a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or it can be an evolved network device in a long-term evolution (long term evolution, LTE) system (evolutional Node B, eNB or e-NodeB), 5G base station (gNB) in the 5G network architecture (next generation system), can also be a home evolved base station (Home evolved Node B, HeNB), relay node (relay node) , a home base station (femto), a pico base station (pico), etc., are not limited in this embodiment of the present application. In some network structures, a network device may include a centralized unit (centralized unit, CU) node and a distributed unit (distributed unit, DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately.

3. Multiplexing transmission: transmit all or part of the information on the uplink channels with different priorities overlapping in the time domain simultaneously on the same uplink channel. If it is partial information, some information that cannot be transmitted on the same determined uplink channel is discarded.

4. UCI transmission in the fifth generation new wireless system (5Generation New RAT, 5G NR):

UCI includes HARQ-ACK, Channel State Information (CSI), Scheduling Request (Scheduling Request, SR) and other information. Wherein, UCI is transmitted on PUCCH.

Among them, HARQ-ACK is a general term for positive acknowledgment (ACKnowledgment, ACK) and negative acknowledgment (Non-ACKnowledgment, NACK), which is used for Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH) or physical communication that requires HARQ-ACK feedback. The downlink control channel (Physical Downlink Control Channel, PDCCH) (such as the PDCCH (also known as SPS PDSCH release) indicating the release of semi-persistent scheduling (Semi-Persistent Scheduling, SPS) resources, and the PDCCH indicating SCell dormancy) is fed back to inform the base station of the PDSCH or Whether the PDCCH that requires HARQ-ACK feedback is received correctly.

CSI is used to feed back the channel quality of downlink transmission, thereby helping the base station to perform better downlink scheduling, such as selecting Modulation and Coding Scheme (MCS) according to CSI, configuring appropriate resource block (Resource Block, RB) resources, etc. .

The SR is used to request allocation of PUSCH transmission resources to the base station for uplink service transmission when the terminal has uplink service to be transmitted.

Specifically, the HARQ-ACK may be fed back based on different time units, and the time unit may be a slot (slot) or a sub-slot (sub-slot). Wherein, the sub-slot is fixedly dividing a time slot into multiple sub-units according to a predetermined sub-slot length. For example, if the length of a sub-slot is 7 symbols, then a time slot including 14 symbols may be divided into 2 sub-slots. For another example, if the length of a sub-slot is 2 symbols, then a time slot including 14 symbols may be divided into 7 sub-slots.

In the case of performing feedback based on a time slot, the time slot where the PUCCH carrying the HARQ-ACK is transmitted is determined according to the feedback timing n+k1. Among them, n is the reference uplink time slot corresponding to the downlink transmission (including PDSCH and PDCCH requiring HARQ-ACK feedback) where HARQ-ACK feedback is required, and k1 is the reference uplink time slot and the transmission HARQ-ACK The time slot offset value between the target time slots (that is, the unit of k1 is a time slot).

In the case of feedback based on sub-slots, determine the sub-slot where the PUCCH transmission carrying HARQ-ACK is located according to the feedback timing n+k1, where n is the downlink transmission that needs to be fed back with HARQ-ACK (including PDSCH and The reference uplink sub-slot corresponding to the time slot where the PDCCH fed back by HARQ-ACK is located, and k1 is the sub-slot offset value between the reference uplink sub-slot and the target sub-slot for HARQ-ACK transmission (that is, the unit of k1 is a subslot). Since the PUCCH resource carrying HARQ-ACK does not cross the time unit used for HARQ-ACK feedback, if the transmission is based on sub-slots, the PUCCH carrying HARQ-ACK will not exceed the sub-slot boundary, that is, it will not cross the transmitted in multiple sub-slots.

6. PUCCH with the same priority overlaps with PUCCH/PUSCH:

Currently, NR Rel-16 does not support parallel transmission of PUCCH and PUSCH at the same time, whether on the same carrier or on different carriers.

Therefore, in the case where PUCCH and PUSCH overlap in time domain resources, UCI (generally HARQ-ACK and CSI) can be transferred from PUCCH to a PUSCH when a predetermined timeline is met. Transmission, if there is an SR, the SR is not transmitted on the PUSCH, and the SR is discarded. It should be noted that, in this document, without special description, the general PUCCH and PUSCH refer to the PUCCH and PUSCH that do not use repeated transmission.

If there are multiple PUSCHs overlapping with the PUCCH, a PUSCH is selected according to the following rules. Among them, the rules are:

Prioritize the selection of PUSCH carrying aperiodic channel state information (Aperiodic CSI, A-CSI);

If there is no PUSCH carrying A-CSI, if there are PUSCHs with PDCCH scheduling (such as DG PUSCH) and PUSCHs without PDCCH scheduling (such as CG PUSCH, SP-CSI PUSCH, etc.), DG PUSCH is preferred;

After selecting according to the above rules, for example, if DG PUSCH is selected or CG PUSCH is selected when there is no DG PUSCH, if there are PUSCHs on multiple carriers, the PUSCH on the carrier with the lower carrier number is preferred; PUSCHs that do not overlap in the time domain overlap with PUCCHs, and the earliest PUSCH is selected.

Among them, 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 with PDCCH scheduling or the HARQ-ACK of the PDCCH indicating the release of downlink SPS resources, then the The PDCCH that schedules PDSCH or the PDCCH that indicates the release of downlink SPS resources is the PDCCH corresponding to PUCCH, or it can also be called the PDCCH that schedules PUCCH. The PDCCH that schedules PUSCH is the PDCCH corresponding to PUSCH. The overlapping PUCCH and PUSCH start time The first symbol of the earliest channel is used as the target symbol. If there are multiple channels with the same starting time, randomly select a channel and use the first symbol as the target symbol. The target symbol needs to meet the following timeline to perform multiplexing transmission , otherwise it is considered as an error scheduling.

Timeline1: The target symbol is not earlier than the first symbol (including CP) after the last symbol of any PDSCH or SPS PDSCH release that requires HARQ-ACK feedback on PUCCH after the T1mux time, that is, the target symbol The time interval between the last symbol of any one of the above PDSCH or SPS PDSCH release is not less than T1mux time. T1mux is related to the processing delay of the 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 starts.

Timeline2: The target symbol is not earlier than the first symbol after the T2mux time after the last symbol of any PDCCH (including the PDCCH requiring HARQ-ACK feedback) that schedules PDSCH (if any) and PUSCH (if any) (including CP included), that is, the time interval between the target symbol and the last symbol of any one of the above PDCCHs is not less than T2mux time. 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 this timeline is to ensure that in the case that UCI needs to be transferred to PUSCH for transmission, the PDCCH for scheduling PUSCH can be obtained before PUCCH starts to prepare, so as to determine that there is no need to prepare UCI transmission on PUCCH, and it can be completed before PUSCH transmission including UCI Inner transmission preparation, that is, complete UCI acquisition and multiplexing processing, and complete TB preparations (such as encoding, modulation, scrambling, etc.); if it is multiplexing between multiple PUCCHs, this T2mux is used to simulate CSI and the preparation time for SR and HARQ-ACK multiplexing.

If the HARQ-ACK carried by the PUCCH does not have a corresponding PDCCH (that is, the HARQ-ACK is the HARQ-ACK of the SPS PDSCH), and there is no PDCCH for scheduling the PDSCH at this time, if there is no PUSCH or the PUSCH has no corresponding PDCCH, you only need to check T1mux Requires check T2mux. If CSI and/or SR are carried on PUCCH, because there is no corresponding PDSCH, check T1mux is not required, and if there is no PUSCH or PUSCH has no corresponding PDCCH, check T2mux is also not required.

If PUCCH and PUCCH overlap, at least one PUCCH is repeatedly transmitted (that is, occupying multiple time slots and repeatedly transmitting UCI in each time slot, also known as multi-slot transmission), then only for overlapping repetitions, according to the transmission height Priority, discarding low priority processing, does not affect non-overlapping repetitions. If the PUCCH and the repeated transmission of the PUSCH overlap, in the case of PUSCH using slot-based repeated transmission (R15 repeated transmission, or R16repetition type A), the UCI carried by the PUCCH is transferred to one or more PUSCH slots that overlap with the PUCCH For transmission; when PUSCH adopts R16repetition type B, the UCI carried by PUCCH is transferred to the earliest actual repetition PUSCH that overlaps with PUCCH and contains more than 1 symbol for transmission (actual repetition is based on unavailable symbols, DL symbols, time The repetition PUSCH obtained after segmenting the slot boundary, etc.); the PUSCH of one or more repetitions overlapping with the PUCCH above all need to meet the multiplexing timeline. If the PUCCH that uses repeated transmission overlaps with the PUSCH that uses or does not use repeated transmission, the PUSCH that overlaps with the PUCCH is discarded to ensure that the repeated transmission of the PUCCH is not interrupted.

R17 can support parallel transmission of PUCCH and PUSCH on different carriers in the case of inter-band CA according to UE capabilities, but does not support parallel transmission on the same carrier or in the case of intra-band CA.

7. Channel transmission with different physical layer priorities:

A UE can support different service types, such as enhanced Mobile Broadband (eMBB) service and Ultra-Reliable and Low Latency Communication (URLLC) service. Different service types have different requirements on reliability and transmission delay. URLLC service flows may occur sporadically and irregularly. Therefore, reserving different system resources independently for different services requires a relatively large overhead on system resources, and the resources reserved for URLLC may not be used in many cases. In order to improve the utilization rate of system resources, multiplexing and transmission of different services on the same resources can be supported. In order to avoid mutual influence between services, different priorities can be defined for different services, so that when resource conflicts occur, which channels and information are more important to be distinguished.

In a specific implementation process, the physical layer priorities of PUCCH and PUSCH can be obtained by default, DCI dynamic indication or RRC semi-static configuration.

For example, when the PUCCH bears 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 high-level signaling.

For another example, when the PUCCH carries the HARQ-ACK of the SPS PDSCH or the HARQ-ACK of the PDCCH indicating the release of SPS resources (that is, the SPS PDSCH release), its priority is the HARQ-ACK codebook configured for the SPS PDSCH through high-layer signaling It is determined by number, the HARQ-ACK codebook corresponding to number 0 is low priority, and the HARQ-ACK codebook corresponding to number 1 is high priority; when PUCCH carries CSI (including periodic CSI and SP-CSI), Its priority defaults to low priority. In the case that the DCI contains a priority indication field, the DCI (or PDCCH) corresponding to the PUCCH and PUSCH can be used. In this application, PDCCH and DCI can be considered equivalent. DCI is a specific format used for PDCCH transmission, and it has the corresponding DCI, etc. The PUCCH that carries the HARQ-ACK of this PDSCH can be indicated through the priority indication field when the PDCCH schedules a PDSCH. Priority; when a PUSCH is scheduled by a PDCCH, the priority indication field can be used to indicate the priority of the scheduled PUSCH, where the PUSCH includes a PUSCH that only carries TB or a PUSCH that only carries A-CSI or a PUSCH that carries both TB and A-CSI PUSCH; for the PUSCH carrying SP-CSI, its priority can be obtained by activating the priority indication field in the DCI of the PUSCH carrying SP-CSI. If the priority indication field is not included in the DCI, or the priority is not configured in high-layer signaling, the default is low priority.

Considering the implementation complexity, Rel-16 does not support multiplexing transmission between uplink channels with different physical layer priorities. When uplink channels with different physical layer priorities collide, that is, multiple PUCCHs overlap in the time domain on the same carrier, or PUCCH and PUSCH overlap in the time domain on the same carrier or different carriers , or when multiple PUSCHs overlap in the time domain on the same carrier, discard low-priority uplink channels and only transmit high-priority uplink channels. Considering that stopping the transmission of low-priority uplink channels based on priority comparison requires a certain amount of additional processing time, the timeline for stopping low-priority uplink channels is further defined: PDCCH corresponding to high-priority uplink channels is required to match the high-priority The time interval between the start symbols of the uplink channel is not less than a predetermined T time, and the original processing delay (such as T1, T2; where T1 is the processing time of PDSCH defined in the agreement (including PDSCH The processing time of receiving decoding and other processing, and the preparation time of related HARQ-ACK feedback, etc.); T2 is the processing time of PUSCH defined in the protocol (including the preparation time of PUSCH, etc.) and the additional time required for stopping (d1).

In Rel-17, considering the impact of system efficiency reduction caused by always discarding low-priority uplink channels, for example, always discarding low-priority HARQ-ACKs will cause the downlink transmission corresponding to low-priority HARQ-ACKs to fail to be timely Obtain feedback information to perform redundant retransmission, and consider supporting multiplexing transmission between uplink channels with different physical layer priorities. At present, it is supported that when the uplink channel carrying low priority HARQ-ACK and the uplink channel carrying high priority HARQ-ACK overlap in time domain resources, the low priority HARQ-ACK and high priority HARQ-ACK can be combined. ACK is transmitted on the same uplink channel according to specific rules, without discarding low-priority HARQ-ACK. When there is a conflict between multiple uplink channels with different priorities, a possible way is to follow the steps below:

Step 1: First resolve conflicts between uplink channels of the same priority, including conflicts between PUCCHs and between PUCCHs and PUSCHs; Use the transmission scheme to find a PUCCH resource to carry UCI on multiple conflicting PUCCHs at the same time, or discard some UCI to resolve conflicts when multiplexing transmission is not supported, so as to obtain one or more non-overlapping low-priority UCIs. PUCCH, if PUCCH exists in the conflict of PUSCH and does not support parallel transmission of PUCCH and PUSCH, it is necessary to determine that a PUSCH bears UCI on the PUCCH that collides with it, so that this PUCCH is not transmitted, and finally one or more non-overlapping low Priority PUCCH/PUSCH; similarly, for high-priority PUCCH, according to the multiplexing transmission scheme between PUCCHs specified in the prior art, find a PUCCH resource to carry UCI on multiple conflicting PUCCHs at the same time, or in When multiplexing transmission is not supported, some UCI is discarded to resolve conflicts, so as to obtain one or more non-overlapping high-priority PUCCHs. If PUCCHs exist in PUSCH conflicts and do not support PUCCH and PUSCH parallel transmission, you need to determine a The PUSCH carries the UCI on the PUCCH that collides with it, so that the PUCCH is not transmitted, and finally one or more high-priority PUCCH/PUSCHs that do not overlap with each other are obtained;

Step 2: Since there may be overlap between high-priority and low-priority uplink channels, it is necessary to further solve the conflict problem between uplink channels with different priorities; it is divided into step 2-1 and step 2-2:

Step 2-1: First resolve the conflict between PUCCHs with different priorities; according to the predetermined multiplexing transmission scheme between different priorities (including discarding a certain UCI when transmitting on the same channel or not supporting multiplexing rules) to obtain one or more non-overlapping PUCCHs (maybe some are low priority, some are high priority, or all may be of a certain priority);

Step 2-2: If there is still PUSCH overlapping with these obtained PUCCHs and parallel transmission of PUCCH and PUSCH is not supported, the conflict between PUCCH and PUSCH needs to be further resolved. At this time, PUCCH and PUSCH may have the same priority or may have different priorities, because although the conflict between PUCCH and PUSCH with the same priority has been resolved in step 1, after the PUCCH multiplexing process with different priorities in step 2-1, according to multiplexing in the same The total number of bits of UCI with high and low priority transmitted on the channel may determine a new PUCCH resource, which may conflict with PUSCH, so multiplex transmission between PUCCH and PUSCH is required, To resolve the conflict between PUCCH and PUSCH.

In addition, whether to support multiplexing transmission between channels with different priorities in Rel-17 can be enabled or disabled based on the semi-static configuration of high-level signaling, or it can be enabled or disabled through a dynamic indication in the PDCCH For this function, the PDCCH can be the PDCCH that schedules downlink transmission, the PDCCH that needs to perform HARQ-ACK feedback, and the PDCCH that schedules the PUSCH.

In the current R17 discussion, in the scenario where channels with different priorities are supported for multiplexing transmission, in the above step 2-2, when performing multiplexing transmission between PUCCH and PUSCH, multiple PUSCHs overlapping with PUCCH may Some support multiplexing with different priorities, while some do not support multiplexing with different priorities. It is also possible that PUCCH and PUSCH support different priority multiplexing configurations. At this time, there is no clear method for how to resolve the conflict between PUCCH and PUSCH. , so that it cannot work properly.

In view of this, the present application provides a channel multiplexing transmission method and device, which determines how to perform transmission according to whether PUCCH and PUSCH support different priority multiplexing, so as to ensure that multiple PUSCHs that overlap with PUCCH in the time domain can be transmitted Select a PUSCH to transmit UCI on PUCCH, or discard low-priority channels to transmit high-priority channels to solve the problem that there is no transmission scheme when PUCCH and PUSCH with different priorities overlap in time domain, and ensure the normal transmission of the system .

Please refer to Figure 1, which is an interactive schematic diagram of a channel multiplexing transmission method provided in the embodiment of the invention. In order to better introduce the channel multiplexing transmission method provided in the embodiment of the present application, the following methods are respectively applied to The specific implementation process of terminal equipment and network equipment is introduced.

In the embodiment of the present application, a channel multiplexing transmission method is provided, the method is applied to a terminal device, and the specific processing process is as follows.

In the embodiment of the present application, when PUCCH and PUSCH overlap in time domain resources, the terminal device performs uplink transmission according to whether PUCCH and/or PUSCH support multiplexing transmission with different priorities; where PUCCH and PUSCH have different priorities .

In the embodiment of the present application, when the terminal device supports multiplexing transmission with different priorities according to whether the PUCCH and/or PUSCH support different priority multiplexing transmissions, it can specifically adopt any of the following methods but not limited to:

Method 1:

The terminal device selects a candidate PUSCH that supports multiplexed transmission with the PUCCH among all PUSCHs that overlap with the PUCCH in time domain resources. Then, the terminal device determines the target PUSCH from the candidate PUSCHs according to the preset PUSCH selection rule, and carries part or all of the UCI on the PUCCH on the target PUSCH for transmission. Wherein, determining part or all of the UCIs on the PUCCH is determined according to a predetermined multiplexing rule, which will not be repeated here.

Specifically, the terminal device carries part or all of the UCI on the PUCCH to the target PUSCH for transmission, which is equivalent to the terminal device transmitting part or all of the UCI originally carried on the PUCCH on the target PUSCH without transmitting the PUCCH.

Specifically, whether to transmit all or part of the UCI on the target PUSCH depends on the pre-defined multiplexing rules. For example, if the UCI carried on the PUCCH contains HARQ-ACK and CSI, and there is no CSI on the target PUSCH, the PUCCH can be transmitted All the UCI that is carried, that is, HARQ-ACK and CSI are carried on the PUSCH for transmission, so that the PUCCH is not transmitted, and if there is CSI on the target PUSCH, because there is already CSI and there is no need to transmit the CSI on the PUCCH, then only the CSI on the PUCCH Part of UCI, that is, HARQ-ACK, is carried on the target PUSCH for transmission, and CSI is discarded along with the PUCCH and not transmitted; for another example, if the UCI carried on the PUCCH includes HARQ-ACK and SR, because SR cannot be transmitted on the PUSCH, only the Part of the UCI carried on the PUCCH, that is, the HARQ-ACK, is carried on the PUSCH for transmission, and the SR is discarded along with the PUCCH and is not transmitted.

That is to say, the terminal device resolves the conflict between the PUCCH and the PUSCH by transmitting part or all of the UCI originally carried on the PUCCH on the target PUSCH without transmitting the PUCCH.

Optionally, in the case that there is no PUSCH that supports multiplexed transmission with PUCCH among all PUSCHs, the terminal device selects to transmit PUCCH and PUSCH according to the priority of PUCCH and the priority of PUSCH overlapping with PUCCH time domain. The uplink channel with higher priority is discarded, and the uplink channel with lower priority among PUCCH and PUSCH is discarded.

That is to say, the terminal device does not transmit the uplink channel with lower priority among PUCCH and PUSCH, so as to resolve the conflict between PUCCH and PUSCH.

Method 2:

The terminal device determines the target PUSCH according to the preset PUSCH selection rule; determines whether to carry part or all of the UCI on the PUCCH to the target PUSCH for transmission according to whether the target PUSCH supports multiplexed transmission with the PUCCH.

Optionally, when the target PUSCH supports multiplexed transmission with the PUCCH, part or all of the UCI on the PUCCH is carried on the target PUSCH for transmission.

That is to say, when the target PUSCH supports multiplexed transmission with the PUCCH, the terminal device can resolve the conflict between the PUCCH and the PUSCH by transmitting part or all of the UCI originally carried on the PUCCH on the target PUSCH without transmitting the PUCCH.

Optionally, if the target PUSCH does not support multiplexed transmission with the PUCCH, according to the priority of the PUCCH and the priority of the target PUSCH, select and transmit the uplink channel with higher priority among the PUCCH and the PUSCH, and discard the PUCCH and the uplink channel with lower priority in PUSCH.

Specifically, in the case where the PUCCH is determined to be an uplink channel with a higher priority, all other PUSCHs that overlap with the PUCCH in time domain resources are discarded; or, when the PUCCH is determined to be an uplink channel with a higher priority, Select a new target PUSCH from the remaining PUSCHs that overlap with PUCCH in time domain resources, and determine whether to carry part or all of the UCI on the PUCCH to the target according to whether the new target PUSCH supports multiplexed transmission with the PUCCH Sending is performed on the PUSCH, and so on, until there is no overlapping of time domain resources of the PUCCH and the PUSCH.

It can be seen that when it is determined that the target PUSCH does not support multiplexing transmission with the PUCCH, that is, the target PUSCH is a PUSCH that has a different priority from the PUCCH and does not support multiplexing with different priorities, the terminal device has a lower priority for PUCCH and PUSCH. The uplink channel of the second level is not sent to resolve the conflict between PUCCH and PUSCH.

In a possible implementation manner, the target PUSCH that supports multiplexed transmission with PUCCH in the above methods 1 and 2 includes: a PUSCH that has different priorities from PUCCH and supports multiplexed transmission with different priorities; PUSCHs with different priorities and supporting multiplex transmission of different priorities, and PUSCHs with the same priority as PUCCH.

Method 3:

The terminal device determines the target PUSCH according to the preset PUSCH selection rule; determines whether to carry part or all of the UCI on the PUCCH on the target PUSCH for transmission according to whether the target PUSCH supports multiplexed transmission with different priorities.

Optionally, when the target PUSCH supports multiplexed transmission with different priorities, part or all of the UCI on the PUCCH is carried on the target PUSCH for transmission.

It can be seen that when the target PUSCH supports multiplexing transmission with different priorities, the terminal device can resolve the conflict between the PUCCH and the PUSCH by transmitting part or all of the UCI originally carried on the PUCCH on the target PUSCH without transmitting the PUCCH.

Optionally, when the target PUSCH does not support multiplexing transmission with different priorities, according to the priority of the PUCCH and the priority of the target PUSCH, select and transmit the uplink channel with higher priority among the PUCCH and PUSCH, and discard the PUCCH and the uplink channel with lower priority in PUSCH.

Specifically, when it is determined that the PUCCH is an uplink channel with a higher priority, all other PUSCHs that overlap with the PUCCH in time domain resources are discarded.

Optionally, in the case of determining that PUCCH is an uplink channel with higher priority, select a new target PUSCH from the remaining PUSCHs that overlap with PUCCH in time domain resources, and select a new target PUSCH according to whether the new target PUSCH supports different priority stage multiplexing transmission to determine whether to carry part or all of the UCI on the PUCCH to the target PUSCH for transmission, and so on until there is no overlapping of time domain resources of the PUCCH and the PUSCH.

It can be seen that, in the case that the target PUSCH does not support multiplexing transmission of different priorities, the terminal device does not transmit the uplink channel with a lower priority among the PUCCH and the PUSCH, so as to resolve the conflict between the PUCCH and the PUSCH.

Method 4:

The terminal device determines whether the PUCCH supports multiplexed transmission with different priorities; if it is determined that the PUCCH does not support multiplexed transmission with different priorities, it sends at least one of the following methods:

Method A: In PUCCH and PUSCH with overlapping time domain resources, select and transmit the uplink channel with higher priority among PUCCH and PUSCH, and discard the uplink channel with lower priority among PUCCH and PUSCH;

Method B: According to the preset PUSCH selection rules, determine the target PUSCH among the PUSCHs that overlap with PUCCH in time domain resources and have the same priority as PUCCH, and carry part or all of the UCI on the PUCCH on the target PUSCH to send.

Among them, the above methods A and B can be used alone or in combination; for example, when using method A, if PUCCH is of high priority, if the reserved high-priority uplink channel also includes PUCCH and PUSCH at the same time, you can Further use method B, that is, select one of the PUSCHs with the same priority as the PUCCH as the target PUSCH, and carry all or part of the UCI on the PUCCH on the target PUSCH, so that the PUCCH is not transmitted; In the case of PUSCH at the lower level, mode A can be further used.

Wherein, whether the PUCCH supports multiplexing with different priorities can be determined according to the configuration of high-level signaling, or according to the indication field in the PDCCH corresponding to the PUCCH to indicate whether multiplexing with different priorities is supported, wherein the PDCCH corresponding to the PUCCH specifically includes: Schedule PDCCH of PDSCH and PDSCH requires HARQ-ACK feedback on PUCCH, or PDCCH that itself needs HARQ-ACK feedback on PUCCH (such as PDCCH indicating SPS PDSCH resource release, PDCCH indicating SCell dormancy, etc.).

Specifically, in the case that the PUCCH supports multiplexing with different priorities, the foregoing manners 1-3 are performed.

In this embodiment of the application, the aforementioned preset PUSCH selection rules are: according to whether the PUSCH carries aperiodic channel state information CSI, the carrier number of the carrier where the PUSCH is located, whether the PUSCH has a corresponding PDCCH, the starting position of the PUSCH, and the priority of the PUSCH One or a combination of levels determines a PUSCH.

Specifically, optional mode 1 is: preferentially select the PUSCH carrying A-CSI. When there is no PUSCH carrying A-CSI, if there is a PUSCH (DG PUSCH) with PDCCH scheduling and a PUSCH (CG PUSCH) without PDCCH scheduling at the same time, SP-CSI PUSCH, etc.), DG PUSCH is preferred. After selecting one of DG PUSCH or CG PUSCH, if there are PUSCHs on multiple carriers, the PUSCH on the carrier with the lower carrier number is preferred. If the selected carrier is There are multiple non-overlapping PUSCHs in the time domain overlapping with the PUCCH, and the earliest PUSCH is selected.

Specifically, option 2 may be a combination of the aforementioned option 1 and priority. For example, first select the PUSCH with the same priority as the PUCCH, and then select the selected PUSCH using the method in the aforementioned optional method 1. If there is no PUSCH with the same priority as the PUCCH, then select the PUSCH with a different priority The method of selecting PUSCH in the prior art (that is, distinguishing the priority of PUSCH) is used in the PUSCH of different levels.

In this embodiment of the present application, PUCCHs with different priorities overlap with PUSCH time domain resources, including: PUCCH has the first priority, and all PUSCHs that overlap with PUCCH time domains have the second priority; or, PUCCH has The first priority, the part of PUSCH that overlaps with the PUCCH in the time domain has the first priority, and the part of PUSCH has the second priority; wherein, the first priority and the second priority are different priorities.

In the embodiment of the present application, when the PUCCH is a PUCCH that simultaneously carries UCIs of different priorities, the priority of the PUCCH is the priority of the UCI with the highest priority among the UCIs with different priorities.

In this embodiment of the present application, whether the PUSCH supports multiplexing with different priorities can be determined according to the configuration of high-layer signaling, or according to the indication field indicating whether multiplexing with different priorities is supported in the PDCCH scheduling the PUSCH.

In the embodiment of the present application, the PUSCH is the PUSCH that cannot be transmitted in parallel with the PUCCH. Specifically, if the UE does not have the ability to transmit the PUCCH and the PUSCH in parallel or the UE has the ability to transmit the PUCCH and the PUSCH in parallel but is not configured to enable this function, then any PUSCH cannot be transmitted in parallel with the PUCCH. Or, the UE has the ability to transmit PUCCH and PUSCH in parallel. This function is also configured to enable this function, but the combination of PUCCH and PUSCH does not meet the parallel transmission conditions. If PUCCH and PUSCH have the same priority, parallel transmission cannot be performed, and PUCCH and PUSCH are different. priority and cannot be transmitted in parallel on the same CC or intra-band CC, only PUCCH and PUSCH have different priorities and can be transmitted in parallel when they are on inter-band CCs.

In the embodiment of the present application, a channel multiplexing transmission method is provided, the method is applied to a network device, and the specific processing process is as follows.

In the case that the PUCCH and the PUSCH overlap in time domain resources, and the PUCCH and the PUSCH have different priorities, uplink reception is performed according to whether the PUCCH and/or the PUSCH support multiplexed transmission with different priorities.

In the embodiment of the present application, when the network device supports multiplexing transmission with different priorities according to whether the PUCCH and/or PUSCH support uplink reception, it can specifically adopt but not limited to any of the following methods:

Method 1:

The network device selects a candidate PUSCH that supports multiplexed transmission with the PUCCH among all PUSCHs that overlap with the PUCCH in time domain resources; determines the target PUSCH from the candidate PUSCHs according to the preset PUSCH selection rules; receives UCI on the target PUSCH , wherein the UCI is transmitted by carrying part or all of the UCI on the PUCCH on the target PUSCH.

Specifically, receiving the UCI on the target PUSCH by the network device is equivalent to receiving part or all of the UCI originally carried on the PUCCH on the target PUSCH, and not receiving the PUCCH.

It can be seen that the network device resolves the transmission conflict between the PUCCH and the PUSCH by receiving part or all of the UCI originally carried on the PUCCH on the target PUSCH and not receiving the PUCCH.

Optionally, when the target PUSCH does not support multiplexed transmission with the PUCCH, according to the priority of the PUCCH and the priority of the target PUSCH, select and receive the uplink channel with higher priority among the PUCCH and PUSCH, and determine the PUCCH Uplink channels with lower priority in PUSCH and PUSCH are discarded.

Specifically, when it is determined that PUCCH is an uplink channel with a higher priority, it is determined that all other PUSCHs that overlap with PUCCH in time domain resources are discarded; or, from the remaining PUSCHs that overlap with PUCCH in time domain resources In the PUSCH, select a new target PUSCH, and determine whether to receive UCI on the target PUSCH according to whether the new target PUSCH supports multiplexed transmission with the PUCCH, where UCI is to carry part or all of the UCI on the PUCCH to the target PUSCH for transmission of.

It can be seen that when it is determined that the target PUSCH does not support multiplexing transmission with the PUCCH, that is, the target PUSCH is a PUSCH that has different priorities from the PUCCH and does not support multiplexing with different priorities, the network device has a lower priority for PUCCH and PUSCH. Level uplink channels are not received to resolve the conflict between PUCCH and PUSCH.

Method 3:

The network device determines the target PUSCH according to the preset PUSCH selection rules; determines whether to receive UCI on the target PUSCH according to whether the target PUSCH supports multiplexing transmission with different priorities, where UCI is to carry part or all of the UCI on the PUCCH to the target PUSCH sent on.

Optionally, in the case that the target PUSCH supports multiplexed transmission with different priorities, UCI is received on the target PUSCH.

It can be seen that when the target PUSCH supports multiplexing transmission with different priorities, the network device can resolve the conflict between the PUCCH and the PUSCH by receiving part or all of the UCI originally carried on the PUCCH on the target PUSCH and not receiving the PUCCH.

Specifically, when it is determined that PUCCH is an uplink channel with a higher priority, it is determined that all other PUSCHs that overlap with PUCCH in time domain resources are discarded; or, from the remaining PUSCHs that overlap with PUCCH in time domain resources In the PUSCH, select a new target PUSCH, and determine whether to receive secondary UCI on the target PUSCH according to whether the new target PUSCH supports multiplexing transmission with different priorities, where UCI is to carry part or all of the UCI on the PUCCH to the target PUSCH. sent.

It can be seen that when the target PUSCH does not support multiplexing transmission with different priorities, the network device does not receive the uplink channel with lower priority among the PUCCH and PUSCH, so as to resolve the conflict between the PUCCH and the PUSCH.

Method 4:

The network device determines whether the PUCCH supports multiplexed transmission with different priorities; if it is determined that the PUCCH does not support multiplexed transmissions with different priorities, it receives at least one of the following methods:

In the PUCCH and PUSCH with overlapping time domain resources, select and receive the uplink channel with higher priority in the PUCCH and PUSCH, and determine that the uplink channel with lower priority in the PUCCH and PUSCH is discarded;

According to the preset PUSCH selection rules, the target PUSCH is determined in the PUSCH that overlaps with the PUCCH in the time domain resource and has the same priority as the PUCCH, and receives UCI on the target PUSCH, where the UCI is part or all of the PUCCH The UCI is carried on the target PUSCH for transmission.

In the embodiment of this application, the preset PUSCH selection rules are: according to whether the PUSCH carries aperiodic channel state information CSI, the carrier number of the carrier where the PUSCH is located, whether the PUSCH has a corresponding PDCCH, the starting position of the PUSCH, and the priority of the PUSCH One or a combination of to determine a PUSCH.

In the embodiment of the present application, the PUSCH is the PUSCH that cannot be transmitted in parallel with the PUCCH.

It should be noted that, in the embodiment of the present application, the aforementioned method 1 may have different priorities for PUSCH and PUCCH (for example, the aforementioned PUCCH has the first priority, and all PUSCHs that overlap with the PUCCH in the time domain have the second priority level), and PUSCH and PUCCH have the same priority or different priorities (that is, the aforementioned PUCCH has the first priority, and some PUSCHs that overlap with PUCCH in the time domain have the first priority, and some PUSCHs have the second priority). . And, mode 3 can be used for PUSCH and PUCCH with different priorities.

Specifically, mode 4 is applicable to the indication field indicating whether different priorities are multiplexed in the PDCCH corresponding to the PUCCH, not only for the conflict resolution before the PUCCH, but also for the conflict resolution between the PUCCH and the PUSCH. And, mode 1-3 is applicable to the indication field indicating whether different priorities are multiplexed in the PDCCH corresponding to PUCCH, and only applies to the conflict resolution before PUCCH, that is, whether the conflict between PUCCH and PUSCH supports different priorities The multiplexing is determined only by looking at the indication fields in the PDCCH corresponding to the PUSCH that indicate whether different priorities are multiplexed.

In the embodiment of the present application, in order to facilitate the understanding of those skilled in the art, several possible ways are listed below to illustrate the technical solution of the channel multiplexing transmission method. The application examples constitute limitations, and other methods may be used in the specific implementation process except for the methods listed below, which are not exhaustive in this article.

Embodiment one:

In this embodiment, it is aimed at the situation that the PUCCH has the first priority, and all the PUSCHs that overlap with the PUCCH in the time domain have the second priority.

Please refer to Figure 2, where LP in Figure 2 represents low priority, HP represents high priority, AN is the abbreviation of HARQ-ACK, HP AN is the HP PUCCH that bears HP AN, and DL grant (authorization) is the corresponding PUCCH PDCCH, UL grant is the PDCCH that schedules the PUSCH, the indication multiplexing in the grant indicates that multiplexing with different priorities is supported, and the indication that no multiplexing indicates that multiplexing with different priorities is not supported.

Optionally, the specific implementation process of implementing the channel multiplexing transmission method in mode 1 is as follows:

In this embodiment, referring to FIG. 3 , the terminal device first selects a PUSCH that supports multiplexing with different priorities among the PUSCHs overlapping with the PUCCH, that is, candidate PUSCHs, and the candidate PUSCHs include LP PUSCH2 and LP PUSCH3.

Then, the terminal device selects a PUSCH in LP PUSCH2 and LP PUSCH3 according to the existing PUSCH selection rule. Exemplarily, assuming that the two PUSCHs, that is, LP PUSCH2 and LP PUSCH3, do not carry A-CSI and both have PDCCH, then according to the principle of the smallest carrier number, select LP PUSCH2 to carry the AN on the PUCCH, that is, the terminal device will carry the AN on the PUCCH The AN is carried on the LP PUSCH2, the LP PUSCH2 carrying the AN is sent, and the PUCCH is discarded, and other PUSCHs can be sent normally.

Moreover, because no PUCCH is sent, there is no conflict between the PUCCH and the PUSCH, and the PUSCHs on multiple carriers can be sent in parallel.

In this embodiment, the network device can determine that the LP PUSCH2 is the PUSCH for transmitting UCI on the PUCCH in the same manner as the terminal device, then the network device can receive the LP PUSCH2 carrying the AN, obtain the AN therefrom, and receive it on other carriers Other PUSCHs do not need to receive PUCCHs.

Optionally, the specific implementation process of implementing the channel multiplexing transmission method in mode 2 or 3 is as follows:

In this embodiment, for mode 2 or mode 3, the terminal device can select a PUSCH based on all PUSCHs overlapping with PUCCH. , select LP PUSCH1 to bear the AN on PUCCH.

Specifically, in the case of adopting mode 2, the terminal device determines how to transmit according to whether the selected LP PUSCH1 supports multiplexing transmission of PUCCH and PUSCH. Specifically: since LP PUSCH1 has different priorities from HP PUCCH, and LP PUSCH1 If the UL grant dynamic indication does not support multiplexing with different priorities, it is determined that the selected LP PUSCH1 does not support multiplexed transmission of PUCCH and PUSCH, so the UCI on the PUCCH cannot be carried on the PUSCH.

In the case of mode 3, determine how to transmit according to whether the selected LP PUSCH1 supports multiplexing with different priorities, specifically: since the UL grant dynamic indication of LP PUSCH1 does not support multiplexing with different priorities, determine the selected LP PUSCH1 does not support multiplexing with different priorities, so the UCI on the PUCCH cannot be carried on the PUSCH.

Please refer to Figure 4, for mode 2 or 3, in order to resolve the conflict between PUCCH and PUSCH, according to the priority, determine to send HP PUCCH, discard LP PUSCH1, and because other LP PUSCH2 and LP PUSCH3 also overlap with HP PUCCH, It also needs to be discarded.

Please refer to Figure 5. After confirming that LP PUSCH1 is discarded, repeat the above selection method for the remaining LP PUSCH2 and LP PUSCH3, and then LP PUSCH2 will be selected to carry AN. According to the judgment conditions of method 2 or 3, it is confirmed that LP PUSCH2 can support Bearer AN, therefore, the terminal device carries AN on PUCCH to LP PUSCH2, sends LP PUSCH2 carrying AN, sends LP PUSCH3, and discards PUCCH and LP PUSCH1.

In this embodiment, the network device determines the final transmission result in the same manner as the terminal device, that is, the network device only receives HP PUCCH, and does not receive LP PUSCH1, LP PUSCH2, and LP PUSCH3.

Optionally, the specific implementation process of implementing the channel multiplexing transmission method in mode 4 is as follows:

In this embodiment, it is possible to determine how to deal with it according to whether the PUCCH supports multiplexing with different priorities. In this embodiment, because the PUCCH supports multiplexing with different priorities, it can be determined according to one of the above methods 1, 2, and 3. The specific behaviors of the terminal side and the base station side are the same as above and will not be described again.

In this embodiment, if the PUCCH indicates that multiplexing of different priorities is not supported, it cannot support carrying the AN on the PUCCH to any PUSCH for transmission. Therefore, methods 1, 2, and 3 are not required to select a PUSCH, and a high-priority channel for transmission can be determined directly according to the priorities of the PUCCH and PUSCH, and low-priority channels are discarded. That is to say, the terminal device can send HP PUCCH, and discard LP PUSCH1, LP PUSCH2, and LP PUSCH3; and, the network device can only receive HP PUCCH, and not receive LP PUSCH1, LP PUSCH2, and LP PUSCH3.

It should be noted that, the explanations of the labels in the foregoing Figures 3-5 are the same as those in Figure 2, and will not be repeated here.

In addition, it should be noted that in the first embodiment above, HP AN is replaced by HP AN+LP AN, that is, HP AN and LP AN are carried in PUCCH, then PUCCH is considered as a high-priority channel, and the above method is also applicable; In the above embodiment, the priorities of the PUCCH and the PUSCH are exchanged, that is, the HP PUCCH is replaced by the LP PUCCH, and the LP PUSCH is replaced by the HP PUSCH. Related methods are also applicable.

Embodiment two:

In this embodiment, it is aimed at the situation that the PUCCH has the first priority, some PUSCHs that overlap with the PUCCH in the time domain have the first priority, and some PUSCHs have the second priority.

Please refer to Figure 6. In Figure 6, LP represents low priority, HP represents high priority, AN is the abbreviation of HARQ-ACK, HP AN is the HP PUCCH that carries HP AN, DL grant is the PDCCH corresponding to PUCCH, and UL grant is the PDCCH corresponding to PUCCH. Grant is the PDCCH for scheduling PUSCH. The indication multiplexing in the grant indicates that multiplexing with different priorities is supported, and the indication that no multiplexing indicates that multiplexing with different priorities is not supported, and the priority of the PUCCH carrying HP AN and LP AN is defined as HP.

The terminal device selects the PUSCHs that support multiplexing with different priorities among the PUSCHs overlapping with the PUCCH, namely LP PUSCH2, LP PUSCH3, HP PUSCH5 and HP PUSCH6; and then selects a PUSCH among these PUSCHs according to the existing PUSCH selection rules.

For example, please refer to Figure 7, the first method: to use the optional method 1 directly, that is, regardless of the priority, assuming that these PUSCHs do not carry A-CSI and all have PDCCH, then according to the carrier number The smallest In principle, choose LP PUSCH2 to carry AN on PUCCH, that is, UE side carries AN (HP AN and LP AN) on PUCCH to LP PUSCH2, sends LP PUSCH2 carrying AN, and discards PUCCH, and other PUSCH can be sent normally .

As an example, please refer to Figure 8, the second way: consider the channel priority, preferentially select the PUSCH with the same priority as the PUCCH, if there are more than one, then reuse the optional method 1 to select, only in HP Choose between PUSCH5 and HP PUSCH6. According to the principle of the smallest carrier number, choose HP PUSCH5 to carry AN on PUCCH, that is, UE side carries AN on PUCCH to HP PUSCH5, sends HP PUSCH5 carrying AN, and discards PUCCH, and others PUSCH can be sent normally.

In this embodiment, the network device adopts the same method as the terminal device. In the first method, it is determined that the LP PUSCH2 is the PUSCH for transmitting UCI on the PUCCH, and then the network device receives the LP PUSCH2 carrying the AN, and obtains the AN therefrom, And receive other PUSCHs on other carriers. In the second mode, it is determined that HP PUSCH5 is the PUSCH for transmitting UCI on the PUCCH, then the network equipment receives the HP PUSCH5 carrying AN, obtains AN therefrom, and receives other PUSCHs on other carriers.

Optionally, the specific implementation process of implementing the channel multiplexing transmission method in mode 2 is as follows:

In this embodiment, the terminal device can implement channel multiplexing transmission in any of the following two ways:

The first implementation method:

In this embodiment, the terminal device directly selects a PUSCH among all PUSCHs overlapping with the PUCCH according to option 1, regardless of the channel priority. For example, assuming that these PUSCHs do not carry A-CSI and all have PDCCH, Based on the minimum number principle, LP PUSCH1 is selected to bear the AN on PUCCH.

Then, the terminal device determines how to transmit according to whether the selected LP PUSCH1 supports the multiplexing transmission of PUCCH and PUSCH. Specifically: since LP PUSCH1 and HP PUCCH have different priorities, and the UL grant dynamic indication of LP PUSCH1 does not support different priorities level multiplexing, then it is determined that the selected LP PUSCH1 does not support the multiplexing transmission of PUCCH and PUSCH, so the UCI on the PUCCH cannot be carried on the PUSCH.

Please refer to Figure 9, in order to solve the conflict between PUCCH and PUSCH, then according to the priority, determine to send HP PUCCH, discard LP PUSCH1, because other LP PUSCH2-3 and HP PUSCH4-6 also overlap with HP PUCCH, then also need to be discarded.

Please refer to Figure 10, in order to resolve the conflict between PUCCH and PUSCH, after it is determined that LP PUSCH1 is discarded, repeat the above selection method for the remaining PUSCH, then LP PUSCH2 will be selected to carry AN, and according to the judgment conditions of method 2, confirm LP PUSCH2 can support carrying AN. Therefore, the UE side carries AN on PUCCH to LP PUSCH2, sends LP PUSCH2 carrying AN, sends LP PUSCH3 and HP PUSCH4-6, and discards PUCCH and LP PUSCH1.

The second implementation method:

In this embodiment, please refer to FIG. 11, the terminal device considers the channel priority, first selects the PUSCH with the same priority as the PUCCH, that is, HP PUSCH4-6, and then determines one of them according to the method of optional mode 1 PUSCH transmits AN, that is, according to the principle of the smallest carrier number, it is determined that HP PUSCH4 carries AN.

Then, the terminal device determines how to transmit according to whether the selected HP PUSCH4 supports multiplexing transmission of PUCCH and PUSCH. Specifically: since HP PUSCH4 and HP PUCCH have the same priority, it is considered to support multiplexing transmission of PUCCH and PUSCH. The HP AN and LP AN on the PUCCH are carried together on this PUSCH for transmission, that is, the UE sends HP PUSCH4 to carry HP AN and LP AN, sends other PUSCHs at the same time, and discards the PUCCH.

In this embodiment, the network device determines the final transmission result in the same manner as the terminal device (for example, the aforementioned first implementation manner or the second implementation manner), and performs corresponding reception.

In this embodiment, first judge how to deal with it according to whether the PUCCH supports multiplexing with different priorities. In this embodiment, because the PUCCH supports multiplexing with different priorities, it is determined that it can be performed in one of the above methods 1 and 2. The specific behaviors of terminal devices and network devices are the same as above and will not be described in detail; in this embodiment, because PUCCH has carried HP AN and LP AN, PUCCH itself supports multiplexing transmission with different priorities, and there is no PUCCH that does not support different priorities. The case of reuse.

It should be noted that the explanations of the labels in the above-mentioned FIGS. 7-11 are the same as those in FIG. 6 , and will not be repeated here.

It should be noted that, for the second embodiment, the PUCCH carrying HP AN and LP AN is replaced by HP AN PUCCH or LP AN PUCCH, and the above method is also applicable.

In addition, it needs to be explained that in the above embodiment, only the PUCCH bears AN as an example, and the related method is also applicable when the PUCCH bears other UCI and supports multiplexing of different priorities for the bearer UCI type; the above-mentioned PUCCH, PUSCH It may also be that all or part of the channels do not have a corresponding grant, or there is no indication field in the corresponding grant indicating whether to support multiplexing with different priorities. At this time, whether the corresponding PUCCH and PUSCH support multiplexing with different priorities can be It is determined according to the configuration of high-level signaling. For example, a high-level parameter is used to configure whether to support multiplexing transmission with different priorities. If it is configured as True, it is considered that any uplink channel supports multiplexing transmission with different priorities, but it is configured as False or If there is no configuration, it is considered that any uplink channel does not support multiplexing transmission with different priorities. In the above embodiment, the HARQ-ACK being unicast or multicast HARQ-ACK is applicable. The time-domain resource overlap in the above-mentioned embodiments is only an example, where PUCCH and one PUSCH may be on the same carrier, or may be on different carriers from all PUSCHs, and the time-domain resource overlap between PUCCH and PUSCH may be the starting point. The start symbol and/or the end symbol can be aligned, or they can be unaligned, that is, full overlap and partial overlap.
