technical field

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

Specifically, different service types have different requirements on reliability and transmission delay. 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, that is, there may be resource conflicts between uplink channels with different physical layer priorities. For example, on the same carrier, channels with different priorities There is overlap between the symbols occupied by the upstream channel. The existing solution is to transmit the channel with high physical layer priority among the conflicting channels, and discard the channel with low physical layer priority.

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

1. Terminal equipment:

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

2. Network equipment:

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

3. Multiplexing transmission: simultaneously transmit information on uplink channels of different priorities that overlap in the time domain on the same uplink channel.

4. Channel transmission with different physical layer priorities:

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

For example, after a UE is scheduled to transmit the eMBB service on resource 1, due to the arrival of the URLLC service, it needs to be scheduled as soon as possible in order to meet the delay requirement of the URLLC service, which may occupy all or all of the resource 1 allocated to the eMBB service. Some resources (including time domain resources and/or frequency domain resources) are used for URLLC transmission.

For another example, it may be that URLLC transmission is scheduled on all or part of the symbols in the time domain resources (symbol set) scheduled for eMBB on the same carrier, regardless of whether the frequency domain resources overlap, because at the same time on the same carrier If two uplink channels cannot be transmitted at the same time, the eMBB service will be interrupted or cancelled by the URLLC service.

In a specific implementation process, the physical layer priority of a physical uplink control channel (Physical Uplink Control Channel, PUCCH) and a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) may be determined. Specifically, it can be obtained in a default manner, a dynamic indication of downlink control information (Downlink Control Information, DCI), or a semi-static configuration of radio resource control (Radio Resource Control, RRC).

In an optional implementation manner, when the PUCCH carries a scheduling request (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 the high-level priority signaling configuration.

In an optional implementation manner, the PUCCH carries a Hybrid Automatic Repeat request-ACKnowledgment (Hybrid Automatic Repeat request-ACKnowledgment) carrying a Semi-Persistent Scheduling (Semi-Persistent Scheduling, SPS) Physical Downlink Shared Channel (PDSCH), HARQ-ACK) or HARQ-ACK carrying the 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 through high-level signaling Yes, the HARQ-ACK codebook corresponding to the number 0 has a low priority, and the HARQ-ACK codebook corresponding to the number 1 has a high priority.

In an optional implementation manner, when the PUCCH carries channel state information (Channel State Indication, CSI), and the CSI includes periodic CSI and semi-persistent channel state information (semi-persistent CSI, SP-CSI), its priority Default is low priority.

In an optional embodiment, when the DCI includes a priority indication field, the DCI (or PDCCH) corresponding to the PUCCH and PUSCH can be used. The specific format, that is, having the corresponding DCI is equivalent to having the priority indication field in the corresponding PDCCH) to obtain the priority.

In an optional embodiment, the DCI used by the PDCCH includes a priority indication field, it can be determined that when a PDSCH is scheduled by the PDCCH, the priority indication field can be used to indicate the priority of the PUCCH carrying the HARQ-ACK of this PDSCH. class. And, when the PDCCH schedules a PUSCH, the priority of the scheduled PUSCH may be indicated by the priority indication field, where the PUSCH includes only the PUSCH carrying the TB or the semi-periodic channel state information (Aperiodic CSI, A-CSI) only. PUSCH or PUSCH carrying both Transport Block (TB) and A-CSI. Specifically, for the PUSCH bearing SP-CSI, its priority can be obtained by activating the priority indication field in the DCI of the PUSCH bearing SP-CSI. If the DCI does not contain a priority indication field, or the higher layer signaling does not have a priority configured, the default is low priority.

5. UCI transmission process in the system:

The technical solutions provided in the present invention may be applicable to various systems, especially 5G systems. For example, applicable systems may be global system of mobile communication (GSM) system, code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) general packet wireless Service (general packet radio service, GPRS) system, long term evolution (long term evolution, LTE) system, LTE frequency division duplex (frequency division duplex, FDD) system, LTE time division duplex (time division duplex, TDD) system, advanced long-term Evolution (longterm evolution advanced, LTE-A) system, universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (worldwide interoperability for microwave access, WiMAX) system, 5G New Radio (New Radio, NR) system, etc. These various systems include terminal equipment and network equipment. The system may also include a core network part, such as an evolved packet system (Evloved Packet System, EPS), a 5G system (5GS), and the like.

In a specific implementation process, uplink control information (Uplink Control Information, UCI) is transmitted on the PUCCH. Specifically, the UCI includes information such as HARQ-ACK, CSI, and SR. Among them, HARQ-ACK is the collective name of ACK and NACK, which is used for feedback on PDSCH or PDCCH indicating SPS resource release (also called SPS PDSCH release), and informs the base station whether PDSCH or PDCCH indicating SPS PDSCH release is correctly received. And, the CSI is used to feed back downlink channel quality, thereby helping the base station to better perform downlink scheduling, such as selecting a modulation and coding level (Modulation and Coding Scheme, MCS) according to the CSI, configuring appropriate resource block (Resource Block, RB) resources, etc.; The SR is used to request the base station for transmission resources of the PUSCH carrying the uplink service when the terminal needs to transmit the uplink service.

As mentioned above, in the prior art, the terminal may transmit the channel with high physical layer priority among the conflicting channels, and discard the channel with low physical layer priority, which may cause the terminal and the base station to disregard low-priority information. Inconsistent understanding of the number of bits will affect the performance of receiving high-priority information.

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

In view of this, an embodiment of the present invention provides a transmission method for an uplink channel. By using the transmission method, when the semi-static high-priority uplink channel and the low-priority uplink channel overlap in the time domain, according to the Whether the channel type of the low-priority uplink channel is semi-static or dynamic determines whether to support multiplexed transmission between uplink channels with different priorities, so as to avoid the terminal and base station from being unfavorable to the low-priority uplink channel due to discarding the low-priority uplink channel. The number of bits of priority information is inconsistently understood, which affects the transmission of high-priority information.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to FIG. 1 , an embodiment of the present invention provides a method for transmitting an uplink channel. The method is performed by a terminal device side, and a specific processing process is as follows.

Step 101: When it is determined that the low-priority uplink channel and the preset type of high-priority uplink channel overlap in the time domain, determine the channel type of the low-priority uplink channel.

In this 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, so as to determine whether multiplexing transmission is required according to the channel type, avoiding the situation of directly discarding the low-priority uplink channel as in the prior art.

Upstream channel.

Step 102: According to the channel type of the low-priority uplink channel, determine whether to support the multiplexed transmission of the uplink channels with different priorities.

In this embodiment of the present invention, when it is determined that the channel type of the low-priority uplink channel is semi-static, it can be determined to support multiplexed transmission of uplink channels of different priorities.

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 aforementioned high-priority uplink channel in the time domain is also When semi-static, due to the semi-static uplink channel, data can be sent or received at the same time-frequency resource position at regular intervals, that is, the low-priority uplink channel and the high-priority uplink channel can be transmitted at the same time , so it can be determined to support multiplexed transmission of uplink channels with different priorities, that is, the aforementioned high-priority uplink channels and low-priority uplink channels that overlap in the time domain can be simultaneously transmitted on the same uplink channel. information on the channel.

In this embodiment of the present invention, the semi-static uplink channel includes an uplink channel that does not have a corresponding PDCCH or an uplink channel that is configured and transmitted by high-level signaling. The type may be periodic, aperiodic, semi-persistent) PUCCH, PUCCH carrying SR, PUSCH carrying SP-CSI, CGPUSCH, etc., which are not described in detail in this embodiment of the present invention.

Manner 2: Determine whether to support multiplexing transmission of uplink channels with different priorities according to configuration signaling; wherein, the configuration signaling is higher layer signaling or medium access control layer control element MAC CE.

Mode 3: When it is determined that the high-priority uplink channel of the preset type is the uplink channel carrying the hybrid automatic repeat request acknowledgement HARQ-ACK of the semi-persistent scheduling physical uplink shared channel SPS PDSCH, the physical downlink control channel of the SPS PDSCH is activated by activating The indication field in the PDCCH determines whether to support multiplexed transmission of uplink channels with different priorities.

In the specific implementation process, support can be implicitly indicated by indicating the number of low-priority bits of high-priority multiplexed transmission in the domain. For example, if the number of bits determined according to the configuration information is 0, it means that different priorities are not supported. For the multiplexed transmission of the uplink channel, if the determined number of bits is greater than 0, it means that the multiplexed transmission of the uplink channel of different priorities is supported.

Manner 4: It is determined to support multiplexed transmission of uplink channels with different priorities, and multiplexed transmission is performed on uplink channels of low priority.

Referring to FIG. 2 , the base station side determines the transmission scheme of the uplink channel provided by the embodiment of the present invention, and the specific processing process of the transmission method of the uplink channel is as follows.

Step 201: when determining that the low-priority uplink channel and the preset type high-priority uplink channel overlap in the time domain, determine the channel type of the low-priority uplink channel;

Step 202: According to the channel type of the low-priority uplink channel, determine whether to support the multiplexed transmission of the uplink channel of different priorities;

That is to say, the execution of step 201 is performed with reference to step 101, and the execution of step 202 is performed with reference to step 102, which will not be repeated here.

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

In order to facilitate the understanding of those skilled in the art, several possible ways are listed below to illustrate the technical solution of uplink channel transmission. It should be understood that the following examples are only schematic descriptions, which do not constitute limitations to the embodiments of the present invention, except for the following For the listed manners, other manners may also be used in the specific implementation process, which is not exhaustive herein.

Example 1:

Referring to FIG. 3, FIG. 3 is a schematic diagram of multiplexed transmission of a high-priority uplink channel and a low-priority according to an embodiment of the present invention. Specifically, in Embodiment 1, the channel types of the high-priority uplink channel and the low-priority uplink channel are both semi-static as an example, and the solution for supporting the multiplexing transmission of uplink channels with different priorities provided by the embodiment of the present invention is carried out. illustrate.

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

Further, one PUCCH resource, that is, 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, can 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 PUCCH resource can be used on this PUCCH resource. Simultaneous transmission of HP SPS AN and LP SPS AN.

It can be seen that when it is determined that the channel types of the high-priority uplink channel and the low-priority uplink channel are both semi-static, it can be determined to support multiplexed transmission of the high-priority uplink channel and the low-priority uplink channel.

Embodiment 2:

Please refer to FIG. 4. FIG. 4 is another schematic diagram in which a high-priority uplink channel and a low-priority uplink channel overlap in the time domain according to an embodiment of the present invention. Specifically, in the second embodiment, an uplink channel with a high priority whose channel type is semi-static and a low-priority uplink channel whose channel type is dynamic is taken as examples, to support or not support the uplink channels of different priorities provided by the embodiment of the present invention. The scheme of multiplexing transmission is described. In FIG. 4 , 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, 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 the HARQ-ACK of the PDSCH scheduled by the PDCCH, it can be directly determined as Multiplex transmission of high priority and LP is not supported, that is, PUCCH with low priority is discarded, and only PUCCH with high priority is transmitted. For example, as shown in FIG. 5 , 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, if it is determined that the type of the low-priority uplink channel is dynamic, it is determined according to the high-level configuration signaling whether it is supported. For example, if it is determined that it is not supported, the low-priority PUCCH can be directly discarded, and only the high-priority PUCCH can be transmitted. For example, as shown in FIG. 5 , in the figure, LP represents low priority, HP represents high priority, AN is the abbreviation of HARQ-ACK, and DLgrant is the abbreviation of control signaling for downlink data transmission.

In this embodiment, if it is determined to support, a PUCCH resource is determined according to a preset multiplexing transmission rule. The way of determining the PUCCH resource can be, for example, to determine a high-priority PUCCH resource in a high-priority PUCCH resource set, High-priority PUCCH and low-priority PUCCH are simultaneously transmitted on this PUCCH resource. For example, as shown in Figure 6, in the figure, LP represents low priority, HP represents high priority, AN is the abbreviation of HARQ-ACK, DL grant is an abbreviation of control signaling for downlink data transmission.

In this embodiment, it is determined whether multiplexing is supported according to the dynamic indication in the PDCCH activation signaling of the SPS PDSCH corresponding to the SPS AN carried by the high-priority PUCCH is activated. 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 activated PDCCH indicates that it is not supported, 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 it is determined that the indication of the dynamic indication is supported, a PUCCH resource is determined according to the preset multiplexing transmission rule, and the high-priority PUCCH and the low-priority PUCCH are simultaneously transmitted on this PUCCH resource. For example, as shown in FIG. 6 , FIG. In the middle, 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 directly determined that the high-priority UCI can be multiplexed and transmitted on the low-priority uplink channel, then according to the preset multiplexing and transmission rule, a PUCCH resource is determined in the low-priority PUCCH resource set, and This PUCCH resource transmits high-priority PUCCH and low-priority PUCCH at the same time. For example, as shown in Figure 7, in the figure, LP means low priority, HP means high priority, AN is the abbreviation of HARQ-ACK, and DL grant is Abbreviation for control signaling for downlink data transmission.

It should be noted that, in the uplink channel transmission method provided in the above embodiment, HARQ-ACK with different priorities can be replaced with unicast and multicast HARQ-ACK, or with other two different UCI transmissions , the same applies.

And, one of the PUCCHs that carry UCI can also be replaced with PUSCH, for example, the low-priority PUCCH in the above embodiment is replaced by a low-priority PUSCH (LP AN may or may not be on the PUSCH), the above implementation The transmission method of the uplink channel provided in the example is also applicable. In the specific implementation process, if it is determined to be a low-priority PUSCH and it is determined to support multiplexing, a new PUCCH will not be determined, but the UCI on the high-priority PUCCH will be transferred to the low-priority PUSCH for transmission. When configuring or scheduling low-priority PUSCHs, the base station can consider that there are always high-priority semi-static UCIs transmitted on it, and knowing the number of bits of these semi-static UCIs, it can make decisions on low-priority PUSCHs. Reasonable scheduling and configuration to ensure the transmission performance of HP semi-static UCI on LP PUSCH. If it is determined that multiplexing is not supported, the low-priority PUSCH is discarded, and the high-priority semi-static PUCCH is transmitted.

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

It should be noted that the above embodiments only take the processing in one time slot as an example, and if the PUCCH is configured for transmission based on sub-slots, it may also be processed in one sub-slot in the above manner.

And, in the above embodiment, it is determined that the low-priority PUCCH carrying the HARQ-ACK of the PDSCH scheduled by the PDCCH and the high-priority PUCCH carrying the HARQ-ACK of the SPS PDSCH are not supported for multiplexing transmission, or the HARQ carrying the SPS PDSCH is determined. - When the number of bits of the HARQ-ACK low-priority PUCCH of the HARQ-ACK multiplexed with the high-priority PUCCH carrying the PDCCH-scheduled PDSCH is 0, it does not necessarily mean that there is no PDCCH carrying the PDCCH in scheduling and transmission. The low-priority PUCCH/PUSCH of the HARQ-ACK of the scheduled PDSCH overlaps with the high-priority PUCCH/PUSCH of the HARQ-ACK carrying the SPS PDSCH, but overlapping transmission actually occurs, but it is determined not to support the configuration or decision-making The two are multiplexed and transmitted, so the low-priority uplink channel needs to be discarded, that is, the high-priority channel does not need to be limited to meet the time conditions for multiplexed transmission.
