Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a transmission method and device for an uplink channel. Background Art

[0002] In 5G NR (5th Generation New RAT), uplink channel transmission with different physical layer priorities can be supported. A single UE (Terminal / User Equipment) can support different service types, such as enhanced Mobile Broadband (eMBB) and Ultra-Reliable and Low Latency Communication (URLLC). Specifically, different service types have different requirements for reliability and transmission latency. To improve system resource utilization, multiplexing different services on the same resources can be supported. This approach can result in an earlier scheduled data transmission being interrupted or canceled by a later scheduled data transmission. To prevent mutual interference between services, different priorities can be defined for different services. This means that uplink channels with different physical layer priorities may conflict with each other. For example, on the same carrier, symbols occupied by uplink channels with different priorities may overlap. The existing solution is to transmit the channel with the higher physical layer priority among the conflicting channels and discard the channel with the lower physical layer priority.

[0003] In the Rel-17 version, in order to avoid discarding uplink control information (UCI) carried on low-priority channels, it is possible to consider supporting UCI on PUCCHs of different physical layer priorities to be multiplexed and transmitted on the same channel.

[0099] In embodiments of the present invention, the term "and / or" describes the association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0100] In the embodiments of the present invention, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0101] In order to better understand the solution provided by the invention, some processes and terms involved in this solution are explained below:

[0102] 1. Terminal equipment:

[0103] The terminal device involved in the embodiments of the present invention may refer to a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called a user equipment (UE). A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile device that exchanges voice and / or data with a radio access network. For example, a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, or a user device, but is not limited in the embodiments of the present invention.

[0104] 2. Network equipment:

[0105] The network device involved in the embodiments of the present invention may be a base station, which may include multiple cells providing services to terminals. Depending on the specific application scenario, a base station may also be referred to as an access point, or may be a device in an access network that communicates with wireless terminal devices over the air interface through one or more sectors, or may be referred to by other names. The network device may be used to convert received air frames into Internet Protocol (IP) packets, and may serve 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 of the air interface. For example, the network device involved in the embodiments of the present invention may be a base transceiver station (BTS) in the Global System for Mobile communications (GSM) or code division multiple access (CDMA), a node in wide-band code division multiple access (WCDMA), an evolutionary node B (eNB or e-NodeB) in the long term evolution (LTE) system, a 5G base station (gNB) in the 5G next generation system, a home evolved node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of the present invention. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.

[0106] 3. Multiplexed transmission: Information on uplink channels of different priorities that overlap in time domain is transmitted simultaneously on the same uplink channel.

[0107] 4. Channel transmission with different physical layer priorities:

[0108] In the specific implementation process, a UE can support different service types, such as enhanced Mobile Broadband (eMBB) services and Ultra-Reliable and Low Latency Communication (URLLC) services. Specifically, different service types have different requirements for reliability and transmission delay. For example, URLLC service flows may occur sporadically and irregularly, so different system resources are reserved independently for different services, which results in a relatively large overhead on system resources. In many cases, the resources reserved for URLLC may not be used. In order to improve the utilization of system resources, multiplexing of different services on the same resources can be supported. However, this approach may result in a situation where an earlier scheduled data transmission is interrupted or canceled by another later scheduled data transmission.

[0109] For example, after a UE is scheduled to transmit an eMBB service on resource 1, due to the arrival of URLLC service, in order to meet the latency requirement of the URLLC service, it needs to be scheduled as soon as possible, and may occupy all or part of the resources (including time domain resources and / or frequency domain resources) in resource 1 that have been allocated to the eMBB service for URLLC transmission.

[0110] For example, URLLC transmission may be scheduled on all or part of the time domain resources (symbol set) scheduled for eMBB on the same carrier, regardless of whether the frequency domain resources overlap. Because two uplink channels cannot be transmitted simultaneously on the same carrier at the same time, the eMBB service will be interrupted or canceled by the URLLC service.

[0111] In a specific implementation, the physical layer priority of the Physical Uplink Control Channel (PUCCH) and the Physical Uplink Shared Channel (PUSCH) can be determined. Specifically, it can be obtained by default, dynamic indication of Downlink Control Information (DCI), or semi-static configuration of Radio Resource Control (RRC).

[0112] In an optional implementation, when the PUCCH carries a Scheduling Request (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-layer signaling.

[0113] In an optional embodiment, when the PUCCH carries a hybrid automatic repeat request acknowledgment (HARQ-ACK) of a semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) or carries a HARQ-ACK of a physical downlink control channel (PDCCH) indicating the release of SPS resources, its priority is determined by the HARQ-ACK codebook number configured for the SPS PDSCH by high-layer signaling, and the HARQ-ACK codebook corresponding to the number 0 is low priority, and the HARQ-ACK codebook corresponding to the number 1 is high priority.

[0114] In an optional implementation, when the PUCCH carries channel state information (CSI), and the CSI includes periodic CSI and semi-persistent CSI (SP-CSI), its priority is low by default.

[0115] In an optional embodiment, when the DCI includes a priority indication field, the priority can be obtained through the priority indication field in the DCI corresponding to PUCCH and PUSCH (or PDCCH, PDCCH and DCI in the present invention can be understood as having the same meaning, DCI is the specific format used for PDCCH transmission, that is, having a corresponding DCI is equivalent to having a corresponding PDCCH).

[0116] In an optional embodiment, the DCI used by the PDCCH includes a priority indication field, then it can be determined that when the PDCCH schedules a PDSCH, the priority of the PUCCH carrying the HARQ-ACK of the PDSCH can be indicated by the priority indication field. Also, when the PDCCH schedules a PUSCH, the priority of the scheduled PUSCH can be indicated by the priority indication field, wherein the PUSCH includes a PUSCH that carries only TBs or a PUSCH that carries only semi-periodic channel state information (Aperiodic CSI, A-CSI) or a PUSCH that carries both transport blocks (Transport Block, TB) and A-CSI. Specifically, 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 DCI does not contain a priority indication field, or the high-level signaling does not configure the priority, the default is low priority.

[0117] 5. UCI transmission process in the system:

[0118] The technical solution provided in the present invention can be applicable to a variety of systems, especially 5G systems. For example, applicable systems can be global system of mobile communication (GSM) system, code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, advanced long term evolution (LTE-A) system, universal mobile telecommunication system (UMTS), world-wide interoperability for microwave access (WiMAX) system, 5G new air interface (NR) system, etc. These multiple systems include terminal equipment and network equipment. The system can also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0119] In the specific implementation process, uplink control information (UCI) is transmitted on PUCCH. Specifically, UCI includes HARQ-ACK, CSI, SR and other information. Among them, HARQ-ACK is a general term for ACK and NACK, which is used to provide feedback for PDSCH or PDCCH indicating SPS resource release (also known as SPS PDSCH release), and inform the base station whether PDSCH or PDCCH indicating SPS PDSCH release is correctly received. In addition, CSI is used to feedback the downlink channel quality, thereby helping the base station to better perform downlink scheduling, such as selecting the modulation and coding scheme (MCS) according to CSI, configuring appropriate resource blocks (RB) resources, etc.; SR is used to request the base station for transmission resources of PUSCH carrying uplink services when the terminal has uplink services to transmit.

[0120] As mentioned above, in the existing technology, the terminal can transmit the channel with high physical layer priority in the conflicting channel and discard the channel with low physical layer priority. This may cause the terminal and the base station to have inconsistent understanding of the number of bits of low-priority information, which will affect the performance of receiving high-priority information.

[0121] It can be seen that there is an urgent need in the prior art for a solution that can solve the above-mentioned problem of simultaneous transmission of low priority and high priority messages.

[0122] In view of this, an embodiment of the present invention provides a transmission method for an uplink channel. Through this transmission method, when a semi-static high-priority uplink channel overlaps with a low-priority uplink channel in the time domain, it can be determined whether to support multiplexing transmission between uplink channels of different priorities based on whether the channel type of the low-priority uplink channel is semi-static or dynamic, thereby avoiding the situation where the terminal and the base station have inconsistent understandings of the number of bits of low-priority information when discarding the low-priority uplink channel, thereby affecting the transmission of high-priority information.

[0123] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention and not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0124] Please refer to Figure 1 , an embodiment of the present invention provides a transmission method for an uplink channel, which is executed by the terminal device side, and the specific processing process is as follows.

[0125] Step 101: When it is determined that a low-priority uplink channel overlaps with a preset type of high-priority uplink channel in the time domain, the channel type of the low-priority uplink channel is determined.

[0126] In an embodiment of the present invention, when it is determined that an uplink channel with a high priority is a semi-static uplink channel, and there is a low-priority uplink channel that overlaps with the aforementioned high-priority uplink channel in the time domain, in this embodiment, the channel type of the low-priority uplink channel can be further determined, thereby determining whether multiplexing transmission is required based on the channel type, thereby avoiding the situation in which the low-priority uplink channel is directly discarded as in the prior art.

[0127] In the embodiment of the present invention, the preset type of high-priority uplink channel is a semi-static uplink channel, wherein the semi-static uplink channel is an uplink channel without a corresponding physical downlink control channel or an uplink channel configured for transmission by higher layer signaling.

[0128] Step 102: Determine whether multiplexing transmission of uplink channels of different priorities is supported according to the channel type of the low-priority uplink channel.

[0129] 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.

[0130] In a specific implementation process, when the channel type of a high-priority uplink channel is semi-static, and there is a low-priority uplink channel that overlaps with the aforementioned high-priority uplink channel in the time domain and the channel type is also semi-static, due to the semi-static uplink channel, data can be sent or received 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 transmitted simultaneously, so it can be determined to support multiplexed transmission of uplink channels of different priorities, that is, information on the aforementioned high-priority uplink channel and the low-priority uplink channel that overlap in the time domain can be transmitted simultaneously on the same uplink channel.

[0131] In an embodiment of the present invention, a semi-static uplink channel includes an uplink channel that does not have a corresponding PDCCH or an uplink channel configured for transmission by high-layer signaling, for example, it may be a PUCCH carrying HARQ-ACK of an SPS PDSCH, a PUCCH carrying CSI (the type of CSI may be periodic, non-periodic, or semi-continuous), a PUCCH carrying SR, a PUSCH carrying SP-CSI, a CGPUSCH, etc., which will not be elaborated in the embodiment of the present invention.

[0132] In an embodiment of the present invention, when the channel type of a low-priority uplink channel is dynamic, whether multiplexing transmission of uplink channels of different priorities is supported is determined in one of the following ways:

[0133] Method 1: Determine that multiplexing transmission of uplink channels with different priorities is not supported.

[0134] In this embodiment of the present invention, when the channel type of a low-priority uplink channel is determined to be dynamic, it can be directly determined that multiplexing of uplink channels of different priorities is not supported. In other words, it is determined that a high-priority uplink channel with a semi-static channel type and a low-priority uplink channel with a dynamic channel type, which overlap in the time domain, cannot be simultaneously transmitted on the same uplink channel.

[0135] Mode 2: Determine whether to support multiplexing transmission of uplink channels of different priorities according to configuration signaling; wherein the configuration signaling is high-layer signaling or a media access control layer control element MAC CE.

[0136] Method 3: When it is determined that the preset type of high-priority uplink channel is an uplink channel carrying the hybrid automatic repeat request confirmation HARQ-ACK of the semi-persistent scheduling physical uplink shared channel SPS PDSCH, it is determined whether multiplexing transmission of uplink channels of different priorities is supported by activating the indication field in the physical downlink control channel PDCCH of the SPS PDSCH.

[0137] During the specific implementation process, support can be implicitly indicated by the number of low-priority bits of the high-priority multiplexing transmission in the indication domain. For example, if the number of bits determined according to the configuration information is 0, it means that the multiplexing transmission of uplink channels of different priorities is not supported. If the determined number of bits is greater than 0, it means that the multiplexing transmission of uplink channels of different priorities is supported.

[0138] Mode 4: Determine to support multiplexing transmission of uplink channels with different priorities, and perform multiplexing transmission on the uplink channel with a low priority.

[0139] In the embodiment of the present invention, if the channel type of the low-priority uplink channel is determined to be dynamic, it can be directly determined to support multiplexing transmission of uplink channels of different priorities, and it can be determined to perform multiplexing transmission on the low-priority uplink channel.

[0140] In the specific implementation process, considering that the low-priority uplink channel is dynamic, the base station scheduling can, to a certain extent, guarantee the transmission performance and delay of the UCI on the semi-static high-priority uplink channel on the low-priority uplink channel. It can be considered that if such an overlapping situation occurs in the base station scheduling, the high-priority UCI will be transferred to the low-priority uplink channel for transmission without affecting the performance and delay of the high-priority UCI, and it can be determined that the multiplexed transmission of uplink channels of different priorities is supported.

[0141] In an embodiment of the present invention, a dynamic uplink channel includes an uplink channel with a corresponding PDCCH, for example, a PUCCH carrying HARQ-ACK of a PDSCH scheduled by a PDCCH, a PUCCH carrying a PDCCH requiring HARQ-ACK feedback (such as a PDCCH indicating SPS PDSCH resource release, a PDCCH indicating Scell ​​Dormancy, etc.), a PUSCH with PDCCH scheduling, etc., which is not limited in the embodiment of the present invention.

[0142] Step 103: Send an uplink channel according to the determination result.

[0143] In an embodiment of the present invention, when it is determined that multiplexing transmission of uplink channels of different priorities is supported, the target physical uplink channel resources can be determined according to the preset multiplexing transmission rules, and the information carried by the low-priority uplink channel and the preset type of high-priority uplink channel can be transmitted simultaneously on the target physical uplink channel resources.

[0144] In the embodiment of the present invention, when it is determined that multiplexing transmission of uplink channels of different priorities is not supported, the uplink channel with a higher priority is transmitted, and the uplink channel with a lower priority is discarded.

[0145] Please refer to Figure 2 , an embodiment of the present invention provides a solution for determining the transmission of an uplink channel on the base station side, and the specific processing process of the uplink channel transmission method is as follows.

[0146] Step 201: When it is determined that a low-priority uplink channel overlaps with a high-priority uplink channel of a preset type in the time domain, determining the channel type of the low-priority uplink channel;

[0147] Step 202: Determine whether multiplexing transmission of uplink channels of different priorities is supported based on the channel type of the low-priority uplink channel;

[0148] Step 203: Receive an uplink channel according to the determination result.

[0149] In an embodiment of the present invention, the method for determining whether to support multiplexing transmission of uplink channels of different priorities is performed in the same manner on both the terminal device side and the base station side, that is, when the uplink channel with a high priority is a semi-static uplink channel, if there is an uplink channel with a low priority that overlaps with the high priority uplink channel in the time domain, then based on the channel type of the low priority uplink channel, it is determined whether to support multiplexing transmission of uplink channels of different priorities. In other words, the execution of step 201 refers to step 101, and the execution of step 202 refers to step 102, which will not be repeated here.

[0150] In an 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. Furthermore, when it is determined that multiplexing transmission of uplink channels of different priorities is not supported, the base station side may only receive the high-priority uplink channels, i.e., not receive the low-priority uplink channels.

[0151] To facilitate understanding by those skilled in the art, several possible methods are listed below to illustrate the technical solution for transmission of the uplink channel. It should be understood that the following examples are merely illustrative and do not limit the embodiments of the present invention. In addition to the methods listed below, other methods may be used in the specific implementation process, which are not exhaustive in this document.

[0152] Example 1:

[0153] See Figure 3 , Figure 3 A schematic diagram of a multiplexed transmission of a high-priority uplink channel and a low-priority uplink channel provided in an embodiment of the present invention. Specifically, Example 1 takes the case where both the high-priority uplink channel and the low-priority uplink channel are semi-static as an example to illustrate the scheme for supporting multiplexed transmission of uplink channels of different priorities provided in an embodiment of the present invention.

[0154] In this embodiment, it can be determined that the low-priority uplink channel is a semi-static uplink channel, for example, a PUCCH carrying HARQ-ACK of an SPS PDSCH ( Figure 3 SPS AN), which can be directly judged as supporting low priority ( Figure 3 HP) and high priority ( Figure 3 Multiplexing transmission of LP. Figure 3 AN in the figure is the abbreviation of HARQ-ACK.

[0155] Furthermore, a PUCCH resource, namely a target PUCCH resource, can be determined based on a preset multiplexing transmission rule. For example, a high-priority PUCCH resource, namely a target PUCCH resource, can be determined from a set of high-priority PUCCH resources. This target PUCCH resource may or may not be the same as the original HP PUCCH resource, so that the HP SPS AN and the LP SPS AN can be transmitted simultaneously on this PUCCH resource.

[0156] It can be seen that when the channel types of the high-priority uplink channel and the low-priority uplink channel are both 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.

[0157] Example 2:

[0158] See Figure 4 , Figure 4 Another schematic diagram of the overlap of a high-priority uplink channel and a low-priority uplink channel in the time domain provided by an embodiment of the present invention. Specifically, embodiment 2 takes an uplink channel with a semi-static high-priority channel type and an uplink channel with a dynamic low-priority channel type as an example to illustrate the scheme of supporting or not supporting multiplexing transmission of uplink channels of different priorities provided by an embodiment of the present invention. Figure 4 In the figure, LP represents low priority, HP represents high priority, AN is the abbreviation of HARQ-ACK, and DL grant is the abbreviation of control signaling for downlink data transmission.

[0159] In this embodiment, if the type of the low-priority uplink channel is determined to be dynamic, for example, a low-priority PUCCH carrying HARQ-ACK of a PDSCH scheduled by a PDCCH ( Figure 4 AN in the abbreviation, it can be directly determined that the 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. Figure 5 As shown in the figure, LP represents low priority, HP represents high priority, AN is the abbreviation of HARQ-ACK, and DL grant is the abbreviation of control signaling for downlink data transmission.

[0160] In this embodiment, if the type of the low-priority uplink channel is determined to be dynamic, whether it is supported is determined according to the high-level configuration signaling. For example, if it is determined not to be supported, the low-priority PUCCH can be directly discarded and only the high-priority PUCCH is transmitted. For example, Figure 5 As shown in the figure, LP represents low priority, HP represents high priority, AN is the abbreviation of HARQ-ACK, and DLgrant is the abbreviation of the control signaling for downlink data transmission.

[0161] In this embodiment, if support is determined, a PUCCH resource is determined according to a preset multiplexing transmission rule. The method of determining the PUCCH resource is, for example, to determine a high-priority PUCCH resource in a high-priority PUCCH resource set, and to transmit a high-priority PUCCH and a low-priority PUCCH simultaneously on this PUCCH resource, for example, Figure 6 As shown in the figure, LP represents low priority, HP represents high priority, AN is the abbreviation of HARQ-ACK, and DL grant is the abbreviation of control signaling for downlink data transmission.

[0162] In this embodiment, whether multiplexing is supported is determined based on the dynamic indication in the PDCCH activation signaling of the SPS PDSCH corresponding to the SPS AN carried by the high-priority PUCCH. It should be noted that, in this embodiment, the indication information of this dynamic indication is valid for all SPS PDSCHs that are subsequently activated and periodically transmitted. If it is determined that the indication information in the activation PDCCH indicates that it is not supported, the low-priority PUCCH can be directly discarded and only the high-priority PUCCH can be transmitted, for example, Figure 5 If it is determined that the dynamic indication is supported, a PUCCH resource is determined according to the preset multiplexing transmission rule, and a high-priority PUCCH and a low-priority PUCCH are transmitted simultaneously on this PUCCH resource, for example, Figure 6As shown in the figure, LP represents low priority, HP represents high priority, AN is the abbreviation of HARQ-ACK, and DL grant is the abbreviation of control signaling for downlink data transmission.

[0163] In this embodiment, it is directly determined that the high-priority UCI can be multiplexed and transmitted on the low-priority uplink channel. Then, according to the preset multiplexing transmission rule, a PUCCH resource is determined in the low-priority PUCCH resource set, and the high-priority PUCCH and the low-priority PUCCH are simultaneously transmitted on this PUCCH resource. For example, Figure 7 As shown in the figure, LP represents low priority, HP represents high priority, AN is the abbreviation of HARQ-ACK, and DL grant is the abbreviation of control signaling for downlink data transmission.

[0164] It should be noted that the uplink channel transmission method provided in the above embodiment can replace HARQ-ACKs of different priorities with unicast and multicast HARQ-ACKs, or with other two different UCI transmissions, which is also applicable.

[0165] Furthermore, one of the PUCCHs carrying UCI can be replaced with a PUSCH. For example, the low-priority PUCCH in the above embodiment can be replaced with a low-priority PUSCH (the PUSCH may or may not have an LP AN). The uplink channel transmission method provided in the above embodiment is also applicable. In a specific implementation, if a low-priority PUSCH is determined and multiplexing is supported, a new PUCCH is not determined. Instead, the UCI on the high-priority PUCCH is transferred to the low-priority PUSCH for transmission. When configuring or scheduling the low-priority PUSCH, the base station can consider that there is always high-priority semi-static UCI for transmission on it. Knowing the number of bits of these semi-static UCIs, the low-priority PUSCH can be reasonably scheduled and configured to ensure the transmission performance of the HP semi-static UCI on the LP PUSCH. If multiplexing is determined not to be supported, the low-priority PUSCH is discarded and the high-priority semi-static PUCCH is transmitted.

[0166] In addition, the high-priority PUCCH carrying the SPS AN in the above embodiment can be replaced with a high-priority PUCCH carrying the SR, and the uplink channel transmission method provided in the above embodiment is also applicable. In the specific implementation process, if it is determined that the high-priority PUCCH carries the SR, the difference is that the multiplexing transmission rules between the SR and the AN may change; for example, replacing the HP PUCCH carrying the SPS AN in the above embodiment with the HP CG PUSCH is also applicable. The difference is that if it is determined that multiplexing is supported, a new PUCCH will not be determined, but the UCI on the low-priority PUCCH will be transferred to the HP PUSCH for transmission.

[0167] It should be noted that the above embodiment only takes the processing in one time slot as an example. If the PUCCH configuration is based on sub-time slot transmission, it can also be processed in one sub-time slot in the above manner.

[0168] In addition, in the above embodiments, when it is determined that the multiplexing transmission of the low-priority PUCCH carrying HARQ-ACK of PDSCH scheduled by PDCCH and the high-priority PUCCH carrying HARQ-ACK of SPS PDSCH is not supported, or when it is determined that the number of bits of the low-priority PUCCH carrying HARQ-ACK of PDSCH scheduled by PDCCH multiplexed with the high-priority PUCCH carrying HARQ-ACK of SPSPDSCH is 0, it does not necessarily mean that there is no overlap between the low-priority PUCCH / PUSCH carrying HARQ-ACK of PDSCH scheduled by PDCCH and the high-priority PUCCH / PUSCH carrying HARQ-ACK of SPS PDSCH in scheduling and transmission, but rather that overlapping transmission actually occurs, but the configuration or decision determines that the multiplexing transmission of the two is not supported. Therefore, the low-priority uplink channel needs to be discarded, that is, there is no need to limit the high-priority channel to meet the time conditions for multiplexing transmission.
