Description

Transmission method and device for uplink channel

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for transmitting an uplink channel.

Background

In a 5G NR (5 Generation New RAT), uplink channel transmissions with different physical layer priorities may be supported, and a UE (Terminal/User Equipment) may support different service types, such as enhanced Mobile Broadband (eMBB) service and Low-Latency high-reliability Communication (URLLC) service. Specifically, different service types have different requirements for reliability and transmission delay. In order to improve the utilization rate of system resources, multiplexing transmission of different services on the same resource can be supported. In this manner, it may occur that an earlier scheduled data transmission is interrupted or cancelled by another later scheduled data transmission. In order to avoid the mutual influence between services, different priorities may be defined for different services, that is, there may be resource conflict between uplink channels with different physical layer priorities, for example, there is overlap between symbols occupied by uplink channels with different priorities on the same carrier. The existing solution is to transmit the channel with high physical layer priority in the conflict channel and discard the channel with low physical layer priority.

In Rel-17, in order to avoid discarding Uplink Control Information (UCI) carried on a channel with a low priority, it may be considered that UCI on PUCCHs supporting different physical layer priorities is multiplexed and transmitted on the same channel, but no specific multiplexing transmission method exists at present.

The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

The term "plurality" in the embodiments of the present invention means two or more, and other terms are similar thereto.

For a better understanding of the solution provided by the invention, some procedures and terms involved in the solution are described below:

1. the terminal equipment:

the terminal device, referred to in the embodiments of the present invention may be a device providing voice and/or data connectivity to a user, a handheld device having a wireless connection function, or other processing device connected to a wireless modem, and the like. In different systems, the names of the terminal devices may be different, for example, in a 5G system, the terminal device may be called a User Equipment (UE). A wireless terminal device, which may be a mobile terminal device such as a mobile phone (or called a "cellular" phone) and a computer having a mobile terminal device, for example, a portable, pocket, hand-held, computer-included or vehicle-mounted mobile device, may communicate with one or more Core Networks (CNs) via a Radio Access Network (RAN), and may exchange languages and/or data with the RAN. Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, session Initiation Protocol (SIP) phones, wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). The wireless terminal device may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile station), a remote station (remote station), an access point (access point), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), and a user device (user device), which are not limited in the embodiments of the present invention.

2. A network device:

the network device related to the embodiment of the present invention may be a base station, and the base station may include a plurality of cells for providing services to the terminal. A base station may also be referred to as an access point, or a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or by other names, depending on the particular application. The network device may be configured to exchange received air frames with Internet Protocol (IP) packets as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communication network. The network device may also coordinate attribute management for the air interface. For example, the network device according to the embodiment of the present invention may be a Base Transceiver Station (BTS) in a Global System for Mobile communications (GSM) or a Code Division Multiple Access (CDMA), may be a network device (NodeB) in a Wideband Code Division Multiple Access (WCDMA), may be an evolved Node B (eNB or e-NodeB) in a Long Term Evolution (LTE) System, may be a 5G Base Station (gNB) in a 5G network architecture (next generation System), may be a Home evolved Node B (HeNB), a relay Node (relay Node), a Home Base Station (femto), a pico Base Station (pico), and the like, which are not limited in the embodiments of the present invention. In some network architectures, a network device may include a Centralized Unit (CU) node and a Distributed Unit (DU) node, which may also be geographically separated.

3. Multiplexing transmission: and simultaneously transmitting the information on the uplink channels with different priorities which are overlapped on the time domain on the same uplink channel.

4. Channel transmission of different physical layer priorities:

in a specific implementation process, one UE may support different service types, such as enhanced Mobile Broadband (eMBB) service, low-Latency and high-reliability Communication (URLLC) service, and the like. Specifically, different service types have different requirements for reliability and transmission delay. For example, the URLLC service flow may be sporadic and sporadic, so different system resources are independently reserved for different services, the overhead on the system resources is relatively large, and the resources reserved for URLLC may not be used in many cases. In order to improve the utilization rate of system resources, multiplexing transmission of different services on the same resource can be supported. However, in this manner, it may result in one earlier scheduled data transmission being interrupted or cancelled by another later scheduled data transmission.

For example, after an eMBB service is scheduled to be transmitted on resource 1, since the URLLC service arrives and scheduling needs to be performed as soon as possible in order to meet the delay requirement of the URLLC service, all or part of resources (including time domain resources and/or frequency domain resources) in resource 1 already allocated to the eMBB service may be occupied for URLLC transmission.

For another example, URLLC transmission may be scheduled on all or part of symbols in time-domain resources (symbol sets) scheduled to the eMBB on the same carrier, regardless of whether frequency-domain resources overlap, since two uplink channels cannot be simultaneously transmitted on the same carrier at the same time, the eMBB service may be interrupted or cancelled by the URLLC service.

In a specific implementation process, a Physical layer priority of a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Shared Channel (PUSCH) may be determined. Specifically, the Information may be obtained by a default mode, a dynamic indication of Downlink Control Information (DCI), or a semi-static configuration of Radio Resource Control (RRC).

In an optional embodiment, when the PUCCH carries a Scheduling Request (SR), the priority of the PUCCH is determined by the priority corresponding to the SR carried by the PUCCH, and the priority corresponding to each SR configuration is configured by higher layer signaling.

In an optional embodiment, when a Hybrid Automatic Repeat request-acknowledgement (HARQ-ACK) carrying a Semi-Persistent Scheduling (SPS) Physical Downlink Shared Channel (PDSCH) or a HARQ-ACK carrying a Physical Downlink Control Channel (PDCCH) indicating SPS resource release is performed on the PUCCH, the priority of the PUCCH is determined by an HARQ-ACK codebook number configured for the SPS through high-layer signaling, the HARQ-ACK corresponding to the number 0 is a low priority, and the HARQ-ACK corresponding to the number 1 is a high priority.

In an alternative embodiment, when the PUCCH carries Channel State Information (CSI), and the CSI includes periodic CSI and semi-persistent CSI (SP-CSI), the priority of the PUCCH is defaulted to low priority.

In an alternative embodiment, when the DCI includes the priority indication field, the priority may be obtained through the priority indication field in the DCI corresponding to the PUCCH and the PUSCH (or the PDCCH, the PDCCH and the DCI may be understood as being equivalent in the present invention, and the DCI is a specific format used for PDCCH transmission, that is, having the corresponding DCI is equivalent to having the corresponding PDCCH).

In an optional implementation manner, the DCI used by the PDCCH includes a priority indication field, and it may be determined that when the PDCCH schedules one PDSCH, the priority of a PUCCH carrying HARQ-ACK of the PDSCH may be indicated by the priority indication field. And 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 TB or a PUSCH only carrying semi-periodic channel state information (Aperiodic CSI, A-CSI) or a PUSCH simultaneously carrying Transport Block (TB) and A-CSI. Specifically, for the PUSCH carrying the SP-CSI, the priority thereof may be obtained by activating a priority indication field in the DCI of the PUSCH carrying the SP-CSI. If the DCI does not contain the priority indication field or the high-layer signaling does not configure the priority, the DCI defaults to the low priority.

5. UCI transmission process in the system:

the technical scheme provided by the invention can be suitable for various systems, particularly 5G systems. For example, suitable systems may be global system for mobile communications (GSM) systems, code Division Multiple Access (CDMA) systems, wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS) systems, long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, long term evolution (long term evolution) systems, LTE-a systems, universal mobile systems (universal mobile telecommunications systems, UMTS), universal internet Access (world interoperability for microwave Access (WiMAX) systems, new Radio interface (NR) systems, etc. These various systems include terminal devices and network devices. The System may further include a core network portion, such as an Evolved Packet System (EPS), a 5G System (5 GS), and the like.

In a specific implementation process, uplink Control Information (UCI) is transmitted on the PUCCH, and specifically, the UCI includes HARQ-ACK, CSI, SR, and other Information. The HARQ-ACK is a general term of ACK and NACK, and is used to perform feedback on the PDSCH or a PDCCH indicating SPS resource release (which may also be referred to as SPS PDSCH release), and inform the base station whether the PDSCH or the PDCCH indicating SPS PDSCH release is correctly received. The CSI is used for feeding back the quality of a downlink channel, so as to help the base station to perform downlink scheduling better, for example, perform Modulation and Coding Scheme (MCS) selection and configure appropriate Resource Block (RB) resources according to the CSI; the SR is used to request the base station for the transmission resource of the PUSCH carrying the uplink service when the terminal has the uplink service to transmit.

As described above, in the prior art, a scheme that a terminal may transmit a channel with a high physical layer priority among conflicting channels and discard a channel with a low physical layer priority may cause inconsistency between understanding of bit numbers of low-priority information by the terminal and a base station, which may affect performance of receiving high-priority information.

Therefore, there is a need in the art for a solution to the above-mentioned simultaneous low-priority and high-priority transmission.

In view of this, an embodiment of the present invention provides a transmission method for uplink channels, by which, when a semi-static high-priority uplink channel and a low-priority uplink channel overlap in a time domain, whether multiplexing transmission between uplink channels of different priorities is supported may be determined according to whether a channel type of the low-priority uplink channel is semi-static or dynamic, so as to avoid that when the low-priority uplink channel is discarded, bit number understanding of low-priority information by a terminal and a base station is inconsistent, thereby affecting high-priority information transmission.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present invention provides a method for transmitting an uplink channel, where the method is executed by a terminal device side, and a specific processing procedure is as follows.

Step 101: and when the uplink channel with the low priority is determined to be overlapped with the preset type of uplink channel with the high priority in the time domain, determining the channel type of the uplink channel with the low priority.

In the embodiment of the present invention, when it is determined that the uplink channel with the high priority is the semi-static uplink channel and there is a low-priority uplink channel overlapping with the aforementioned high-priority uplink channel in the time domain, in this embodiment, the channel type of the low-priority uplink channel may be further determined, so as to determine whether multiplexing transmission is required according to the channel type, thereby avoiding a situation that the low-priority uplink channel is directly discarded as in the prior art.

In the embodiment of the present invention, the high-priority uplink channel of the preset type is a semi-static uplink channel, where the semi-static uplink channel is an uplink channel without a corresponding physical downlink control channel or an uplink channel configured and transmitted by a high-level signaling.

Step 102: and determining whether multiplexing transmission of the uplink channels with different priorities is supported or not according to the channel type of the uplink channel with the low priority.

In the embodiment of the present invention, when it is determined that the channel type of the low priority uplink channel is semi-static, it may be determined that multiplexing transmission of uplink channels of different priorities is supported.

In a specific implementation process, when the channel type of the high-priority uplink channel is semi-static, and the channel type of the low-priority uplink channel that overlaps with the high-priority uplink channel in the time domain is also semi-static, because the semi-static uplink channel can transmit or receive data at the same time-frequency resource position every fixed period, that is, the low-priority uplink channel and the high-priority uplink channel can be simultaneously transmitted, it can be determined that multiplexing transmission of uplink channels with different priorities is supported, that is, information on the high-priority uplink channel and the low-priority uplink channel that overlap in the time domain can be simultaneously transmitted on the same uplink channel.

In the embodiment of the present invention, the semi-static uplink channel includes an uplink channel without a corresponding PDCCH or an uplink channel configured and transmitted by a higher layer signaling, for example, the semi-static uplink channel may be a PUCCH carrying HARQ-ACK of an SPS PDSCH, a PUCCH carrying CSI (the type of CSI may be periodic, aperiodic, or semi-persistent), a PUCCH carrying SR, a PUSCH carrying SP-CSI, a CG PUSCH, or the like, which is not described in detail in the embodiment of the present invention.

In the embodiment of the present invention, when the channel type of the low priority uplink channel is dynamic, whether multiplexing transmission of uplink channels with different priorities is supported is determined according to one of the following manners:

mode 1: and determining that the multiplexing transmission of the uplink channels with different priorities is not supported.

In the embodiment of the present invention, when it is determined that the channel type of the low-priority uplink channel is dynamic, it may be directly determined that multiplexing transmission of uplink channels of different priorities is not supported. That is, it is determined that an uplink channel with a high priority and a dynamic low priority, which are overlapped in a time domain and have a semi-static channel type, cannot be simultaneously transmitted on the same uplink channel.

Mode 2: determining whether multiplexing transmission of uplink channels with different priorities is supported or not according to the configuration signaling; the configuration signaling is a high-level signaling or a media access control layer control element (MAC CE).

Mode 3: when the preset type of uplink channel with high priority is determined to be the uplink channel of hybrid automatic repeat request acknowledgement HARQ-ACK carrying a semi-persistent scheduling physical uplink shared channel (SPS PDSCH), whether multiplexing transmission of the uplink channels with different priorities is supported or not is determined by activating an indication field in a Physical Downlink Control Channel (PDCCH) of the SPS PDSCH.

In a specific implementation process, whether the multiplexing transmission of the uplink channels with different priorities is supported or not can be implicitly represented by indicating the bit number of the low priority of the high priority multiplexing transmission in the domain, for example, if the bit number determined according to the configuration information is 0, it indicates that the multiplexing transmission of the uplink channels with different priorities is not supported, and if the determined bit number is greater than 0, it indicates that the multiplexing transmission of the uplink channels with different priorities is supported.

In the embodiment of the present invention, if it is determined that the channel type of the low-priority uplink channel is dynamic, it may be directly determined to support multiplexing transmission of uplink channels of different priorities, and it may be determined to perform multiplexing transmission on the low-priority uplink channel.

In a specific implementation process, considering that an uplink channel with a low priority is dynamic, scheduling of a base station may ensure, to a certain extent, transmission performance and delay of UCI on a semi-static uplink channel with a high priority on the uplink channel with a low priority, and it may be considered that if such an overlapping situation occurs in scheduling of the base station, the UCI with a high priority is transferred to the uplink channel with a low priority for transmission, and the performance and delay of the UCI with a high priority are not affected, that is, it may be determined that multiplexing transmission of uplink channels with different priorities is supported.

In the embodiment of the present invention, the dynamic uplink channel includes an uplink channel having a corresponding PDCCH, for example, a PUCCH carrying HARQ-ACK of a PDSCH scheduled by the PDCCH, a PUCCH carrying HARQ-ACK of a PDCCH which needs to perform HARQ-ACK feedback (for example, a PDCCH indicating SPS PDSCH resource release, a PDCCH indicating Scell downlink, and the like), a PUSCH having PDCCH scheduling, and the like, which is not limited in the embodiment of the present invention.

Step 103: and sending the uplink channel according to the determination result.

In the embodiment of the present invention, when determining that multiplexing transmission of uplink channels with different priorities is supported, a target physical uplink channel resource may be determined according to a preset multiplexing transmission rule, and information carried by an uplink channel with a low priority and an uplink channel with a high priority of a preset type may be transmitted simultaneously on the target physical uplink channel resource.

In the embodiment of the invention, when the multiplex transmission of the uplink channels with different priorities is determined not to be supported, the uplink channel with high priority is transmitted, and the uplink channel with low priority is discarded.

Referring to fig. 2, a scheme for determining transmission of an uplink channel at a base station side according to an embodiment of the present invention includes the following specific processing procedures.

Step 201: when the uplink channel with the low priority is determined to be overlapped with the uplink channel with the high priority of a preset type in a time domain, determining the channel type of the uplink channel with the low priority;

step 202: determining whether multiplexing transmission of uplink channels with different priorities is supported or not according to the channel type of the uplink channel with the low priority;

step 203: and receiving the uplink channel according to the determination result.

In the embodiment of the present invention, the terminal device side and the base station side both perform the same method for determining whether to support the multiplexing transmission of the uplink channels with different priorities, that is, when the uplink channel with high priority is a semi-static uplink channel, if there is an uplink channel with low priority and an uplink channel with high priority overlapping in a time domain, it is determined whether to support the multiplexing transmission of the uplink channels with different priorities according to the channel type of the uplink channel with low priority. That is, the step 201 is performed with reference to the step 101, and the step 202 is performed with reference to the step 102, which is not described herein again.

In the embodiment of the present invention, when it is determined that multiplexing transmission of uplink channels of different priorities is supported, the base station side may receive the uplink channels according to a preset multiplexing transmission rule. And when determining that the multiplexing transmission of the uplink channels with different priorities is not supported, the base station side may receive only the uplink channel with high priority, that is, not receive the uplink channel with low priority.

To facilitate understanding of those skilled in the art, the following describes several possible ways to describe the technical solution of uplink channel transmission, and it should be understood that the following examples are only illustrative and do not limit the embodiments of the present invention, and other ways may be adopted in the specific implementation process except the ways listed below, which are not exhaustive herein.

The first embodiment is as follows:

referring to fig. 3, fig. 3 is a schematic diagram of a high-priority uplink channel and a low-priority multiplexing transmission according to an embodiment of the present invention. Specifically, in the first embodiment, the channel types of the high-priority uplink channel and the low-priority uplink channel are both semi-static, and the scheme for supporting multiplexing transmission of uplink channels with different priorities provided in the first embodiment of the present invention is described.

In this embodiment, it may be determined that the uplink channel with the low priority is a semi-static uplink channel, for example, a PUCCH carrying HARQ-ACK of SPS PDSCH (abbreviated as SPS AN in fig. 3), that is, it may be directly determined to support multiplexing transmission with low priority (abbreviated as HP in fig. 3) and high priority (abbreviated as LP in fig. 3). And the AN in FIG. 3 is AN abbreviation for HARQ-ACK.

Further, one PUCCH resource, i.e., a target PUCCH resource, may be determined according to a preset multiplexing transmission rule. For example, a high-priority PUCCH resource, that is, a target PUCCH resource, may be determined from the high-priority PUCCH resource set, and the target PUCCH resource may be the same as or different from the original HP PUCCH resource, so that the HP SPS AN and the LP SPS AN may be transmitted simultaneously on the PUCCH resource.

Therefore, when the channel types of the high-priority uplink channel and the low-priority uplink channel are determined to be semi-static, it can be determined that the high-priority uplink channel and the low-priority uplink channel are supported for multiplexing transmission.

Example two:

referring to fig. 4, fig. 4 is another schematic diagram of overlapping a high-priority uplink channel and a low-priority uplink channel in a time domain according to an embodiment of the present invention. Specifically, the second embodiment takes an uplink channel with a semi-static channel type and a high priority level and an uplink channel with a dynamic channel type and a low priority level as examples, and explains the scheme of supporting or not supporting the multiplexing transmission of uplink channels with different priorities provided by the second embodiment of the present invention. In fig. 4, LP denotes low priority, HP denotes high priority, AN is AN abbreviation of HARQ-ACK, and DL grant is AN abbreviation of control signaling for downlink data transmission.

In this embodiment, if it is determined that the type of the low-priority uplink channel is dynamic, for example, the low-priority PUCCH (abbreviated as AN in fig. 4) carrying HARQ-ACK of PDSCH scheduled by PDCCH, it may be directly determined that multiplexing transmission of high priority and LP is not supported, that is, the low-priority PUCCH is discarded, and only the high-priority PUCCH is transmitted. For example, as shown in fig. 5, in the figure, LP represents low priority, HP represents high priority, AN is AN abbreviation for HARQ-ACK, and DL grant is AN abbreviation for control signaling for downlink data transmission.

In this embodiment, if it is determined that the type of the uplink channel with low priority is dynamic, and it is determined whether the uplink channel with low priority is supported according to the higher layer configuration signaling, for example, it is determined that the uplink channel with low priority is not supported, the PUCCH with low priority may be directly discarded, and only the PUCCH with high priority is transmitted, for example, as shown in fig. 5, where LP represents low priority, HP represents high priority, AN is AN abbreviation for HARQ-ACK, and DL grant is AN abbreviation for control signaling for downlink data transmission.

In this embodiment, if the determination is supported, a PUCCH resource is determined according to a preset multiplexing transmission rule, for example, a high-priority PUCCH resource may be determined in a high-priority PUCCH resource set, and the high-priority PUCCH and the low-priority PUCCH are simultaneously transmitted on the PUCCH resource, for example, as shown in fig. 6, where LP represents low priority, HP represents high priority, AN is short for HARQ-ACK, and DL grant is short for control signaling for downlink data transmission.

In this embodiment, it is determined whether multiplexing is supported according to a dynamic indication in a PDCCH activation signaling of AN SPS PDSCH corresponding to AN SPS AN carried by AN activated high priority PUCCH. It should be noted that, in this embodiment, the indication information of the dynamic indication is valid for all SPS PDSCHs that are activated and periodically transmitted subsequently. If it is determined that the indication information in the activated PDCCH indicates non-support, the PUCCH with low priority may be directly discarded, and only the PUCCH with high priority may be transmitted, for example, as shown in fig. 5. If the indication support of the dynamic indication is determined, a PUCCH resource is determined according to the preset multiplexing transmission rule, and a high-priority PUCCH and a low-priority PUCCH are simultaneously transmitted on the PUCCH resource, for example, as shown in fig. 6, in the drawing, LP indicates low priority, HP indicates high priority, AN is short for HARQ-ACK, and DL grant is short for control signaling for downlink data transmission.

In this embodiment, it is directly determined that UCI with high priority can be transmitted in a multiplexing manner on AN uplink channel with low priority, and then according to a preset multiplexing transmission rule, a PUCCH resource is determined in a PUCCH resource set with low priority, and the PUCCH resource with high priority and the PUCCH resource with low priority are simultaneously transmitted on this PUCCH resource, for example, as shown in fig. 7, in the drawing, LP represents low priority, HP represents high priority, AN is AN abbreviation of HARQ-ACK, and DL grant is AN abbreviation of control signaling for downlink data transmission.

It should be noted that, in the transmission method of the uplink channel provided in the foregoing embodiment, HARQ-ACKs of different priorities may be replaced by unicast and multicast HARQ-ACKs, or replaced by other two different UCI transmissions, and the method is also applicable.

Also, one of the PUCCHs carrying the UCI may be replaced by a PUSCH, for example, the low-priority PUCCH in the above embodiment is replaced by a low-priority PUSCH (there may be AN LP AN on the PUSCH, or there may be no LP AN on the PUSCH), and the transmission method of the uplink channel provided in the above embodiment is also applicable. In the specific implementation process, if the PUSCH is determined to be a low-priority PUSCH and multiplexing is determined to be supported, a new PUCCH is not determined, UCI on the high-priority PUCCH is transferred to the low-priority PUSCH for transmission, and when the base station configures or schedules the low-priority PUSCH, it can be considered that semi-static UCI with high priority is always transmitted on the low-priority PUCCH, and the number of bits of the semi-static UCI is known, reasonable scheduling and configuration can be performed on the low-priority PUSCH, so that the transmission performance of HP semi-static UCI on LP PUSCH is ensured. And if the multiplexing is not supported, discarding the PUSCH with the low priority, and transmitting the semi-static PUCCH with the high priority.

In addition, the high-priority PUCCH carrying SPS AN in the above embodiment may be replaced by the high-priority PUCCH carrying SR, and the uplink channel transmission method provided in the above embodiment is also applicable. In a specific implementation process, if a high-priority PUCCH carrying AN SR is determined, what is different is that a multiplexing transmission rule between the SR and AN may change; for another example, replacing the HP PUCCH carrying SPS AN in the above embodiment with the HP CG PUSCH is also applicable, except that if it is determined that multiplexing is supported, a new PUCCH is not determined, and UCI on the low priority PUCCH is transferred to the HP PUSCH for transmission.

It should be noted that, in the above embodiment, only the processing in one slot is taken as an example, and if the PUCCH configuration is based on transmission in a sub-slot, the processing may also be performed in one sub-slot in the manner described above.

And in the above embodiment, when it is determined that the low-priority PUCCH carrying the HARQ-ACK of the PDSCH scheduled by the PDCCH is not supported for the high-priority PUCCH multiplexing transmission or that the bit number of the low-priority PUCCH carrying the HARQ-ACK of the PDSCH scheduled by the PDCCH multiplexed with the high-priority PUCCH carrying the HARQ-ACK of the SPS PDSCH is 0, the low-priority PUCCH/PUSCH carrying the HARQ-ACK of the PDSCH scheduled by the PDCCH is not necessarily overlapped with the high-priority PUCCH/PUSCH carrying the HARQ-ACK of the SPS PDSCH scheduled by the PDCCH, but the overlapping transmission actually occurs, but it is determined that the two multiplexing transmissions are not supported in configuration or decision, so it is necessary to discard the low-priority uplink channel, that is, it is not necessary to restrict the high-priority channel to satisfy the time condition of the multiplexing transmission.
