Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to wireless communication methods and devices. Background Technology

[0002] In New Radio (NR) Release 16 (Rel-16), high and low priorities were introduced at the physical layer for uplink channels to better support Ultra-Reliable Low Latency (URLLC) services. Specifically, network devices can be configured to provide terminal devices with two feedback codebooks, one for carrying acknowledgment (ACK) or negative acknowledgment (NACK) feedback information of different priorities, and the other for carrying ACK / NACK information. Priority index 0 represents low priority, and priority index 1 represents high priority. The uplink channel carrying ACK / NACK information has the same priority as the feedback codebook it carries, and other uplink channels will also correspond to priority index 0 or priority index 1. Different priority channels have different transmission performance requirements, including reliability and latency.

[0003] In NR R16 systems, when uplink channels of different priorities overlap in the time domain, only the high-priority channel is transmitted, and the low-priority channel is discarded. However, while transmitting only the high-priority channel ensures its transmission, it cannot guarantee the transmission of the low-priority channel, thus reducing system transmission efficiency and reliability.

[0004] Therefore, regarding the transmission of feedback information, there is an urgent need in this field for a wireless communication method to improve system transmission efficiency and reliability. Summary of the Invention

[0005] This application provides a wireless communication method and device that can improve system transmission efficiency and reliability.

[0015] Send a first indication message, which is used to indicate that feedback information is transmitted in a time unit using either the first feedback codebook or the third feedback codebook. The third feedback codebook includes all the information in the at least one first feedback message and part or all of the information in the at least one second feedback message. The size of the third feedback codebook is the same as the size of the first feedback codebook.

[0016] Fifthly, a communication device is provided for implementing the methods of any one of the first to fourth aspects or their respective implementations. Specifically, it includes a functional module for performing the methods of any one of the possible implementations of the first to fourth aspects.

[0017] In one implementation, the communication device may include a transmitting unit and / or a receiving unit. The transmitting unit performs functions related to transmitting, and the receiving unit performs functions related to receiving. For example, the transmitting unit may be a transmitter or a receiver, and the receiving unit may be a receiver or a transmitter. Alternatively, the communication device may be a communication chip, and the receiving unit may be an input circuit or interface of the communication chip, while the transmitting unit may be an output circuit or interface of the communication chip.

[0018] In one implementation, the communication device is a terminal device, or the communication device is a network device. The terminal device is used to perform the methods in the first aspect, the third aspect, or any possible implementation of the first aspect and the third aspect. The network device is used to perform the methods in the second aspect, the fourth aspect, or any possible implementation of the second aspect and the fourth aspect.

[0019] A sixth aspect provides a communication device for implementing the methods of any one of the first to fourth aspects or their respective implementations. Specifically, it includes a processor and a memory for storing a computer program, the processor for calling and running the computer program from the memory, causing the communication device to execute the methods of any one of the first to fourth aspects or their respective implementations.

[0020] In one implementation, there are one or more processors and one or more memories.

[0026] Ninthly, a computer-readable storage medium is provided for storing a computer program that causes a computer to perform the methods of any one of the first to fourth aspects or their respective implementations.

[0028] Eleventhly, a computer program is provided that, when run on a computer, causes the computer to perform the methods of any one of the first to fourth aspects or their respective implementations.

[0029] Based on the above technical solutions, when the feedback resources used to carry the first feedback codebook overlap with those used to carry the second feedback codebook, using the third feedback codebook to transmit all information in at least one first feedback message and part or all information in at least one second feedback message can avoid completely discarding the at least one second feedback message, thus improving system efficiency. Furthermore, since the size of the third feedback codebook is the same as the size of the first feedback codebook, it is advantageous to generate the third feedback codebook using the same method as generating the first feedback codebook, avoiding significant modifications to the transmission process of the at least one first feedback message and ensuring the reliability of the at least one first feedback message.

[0044] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0045] Figure 1 This is a schematic diagram of an application scenario according to an embodiment of this application.

[0046] like Figure 1 As shown, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 can communicate with the terminal device 110 via an air interface. Multi-service transmission is supported between the terminal device 110 and the network device 120.

[0047] It should be understood that the embodiments of this application are only illustrated by way of example with communication system 100, but the embodiments of this application are not limited thereto. That is to say, the technical solutions of the embodiments of this application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), 5G communication system (also known as New Radio (NR) communication system), or future communication systems, etc.

[0048] exist Figure 1 In the communication system 100 shown, network device 120 may be an access network device that communicates with terminal device 110. The access network device can provide communication coverage for a specific geographical area and can communicate with terminal device 110 (e.g., UE) located within that coverage area.

[0049] Network device 120 may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, a Next Generation Radio Access Network (NG RAN) device, a base station (gNB) in an NR system, a radio controller in a Cloud Radio Access Network (CRAN), or a relay station, access point, vehicle-mounted device, wearable device, hub, switch, bridge, router, or network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0050] Terminal device 110 can be any terminal device, including but not limited to terminal devices that are connected to network device 120 or other terminal devices via wired or wireless connections.

[0051] For example, the terminal device 110 may refer to an access terminal, user equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. The access terminal may be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, in-vehicle device, wearable device, terminal device in a 5G network, or terminal device in a future evolved network, etc.

[0052] Terminal device 110 can be used for device-to-device (D2D) communication.

[0053] The wireless communication system 100 may further include a core network device 130 that communicates with the base station. This core network device 130 may be a 5G core network (5G Core, 5GC) device, such as an Access and Mobility Management Function (AMF), an Authentication Server Function (AUSF), a User Plane Function (UPF), or a Session Management Function (SMF). Optionally, the core network device 130 may also be an Evolved Packet Core (EPC) device for an LTE network, such as a Session Management Function + Core Packet Gateway (SMF+PGW-C) device. It should be understood that SMF+PGW-C can simultaneously implement the functions of both SMF and PGW-C. During network evolution, the aforementioned core network device may also be called by other names, or new network entities may be formed by dividing the core network functions; this embodiment does not limit this.

[0054] The various functional units in the communication system 100 can also establish connections and communicate with each other through the next generation (NG) interface.

[0055] For example, terminal devices establish air interface connections with access network devices through the NR interface for transmitting user plane data and control plane signaling; terminal devices can establish control plane signaling connections with the AMF through NG interface 1 (N1); access network devices, such as next-generation radio access base stations (gNB), can establish user plane data connections with the UPF through NG interface 3 (N3); access network devices can establish control plane signaling connections with the AMF through NG interface 2 (N2); the UPF can establish control plane signaling connections with the SMF through NG interface 4 (N4); the UPF can interact with the data network for user plane data through NG interface 6 (N6); the AMF can establish control plane signaling connections with the SMF through NG interface 11 (N11); and the SMF can establish control plane signaling connections with the PCF through NG interface 7 (N7).

[0056] Figure 1 An exemplary embodiment shows a base station, a core network device, and two terminal devices. Optionally, the wireless communication system 100 may include multiple base station devices, and each base station may include other numbers of terminal devices within its coverage area. This application embodiment does not limit this.

[0057] It should be understood that any device with communication functionality in the network / system described in this application embodiment can be referred to as a communication device. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include a network device 120 and a terminal device 110 with communication functions. The network device 120 and the terminal device 110 may be the devices described above, which will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as network controllers, mobility management entities and other network entities. This application embodiment does not limit this.

[0058] It should be understood that the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0059] In NR R15, two ACK / NACK message generation methods are supported: semi-static HARQ-ACK codebook and dynamic HARQ-ACK codebook. The semi-static HARQ-ACK codebook is also known as the Type-1 feedback codebook, and the dynamic HARQ-ACK codebook is also known as the Type-2 feedback codebook.

[0060] The Type-1 feedback codebook uses a semi-static method to determine the number of ACK / NACK feedback bits corresponding to the PDSCH. That is, the number of ACK / NACK bits included in the feedback codebook does not depend on the actual number of PDSCHs received, but is determined based on the semi-statically configured downlink resources available for PDSCH transmission (i.e., the maximum number of PDSCHs that can be received). The advantage of this method is that it avoids ambiguity between the terminal and the base station regarding the size of the ACK / NACK feedback codebook caused by the terminal not receiving some PDSCHs, ensuring that the base station can correctly receive the feedback information sent by the terminal. However, the disadvantage of this method is the large feedback overhead, as reserved feedback bits must be allocated to all downlink resources that may transmit PDSCHs.

[0061] Figure 2 This is a schematic diagram of a PDSCH candidate reception opportunity within a time slot provided in an embodiment of this application.

[0062] like Figure 2 As shown, since a terminal can receive at most one PDSCH at any given time within a carrier, that is... Figure 2 A time slot can be a set of PDCCH monitoring occasions, which may include PDSCH candidate receptions 1-5. PDSCH candidate reception 1 will not be transmitted simultaneously with PDSCH candidate receptions 2 and 3, and PDSCH candidate receptions 4 and 5 will not be transmitted simultaneously. If corresponding feedback information bits are reserved for PDSCH candidate receptions 1-5 in the type-1 codebook, feedback information redundancy will inevitably exist. However, if multiple PDSCH candidate receptions within the same time slot share a single feedback information bit, feedback overhead can be reduced. That is, when the terminal receives PDSCH in any of PDSCH candidate receptions 1, 2, or 3, its corresponding ACK / NACK information is mapped to a single bit; when the terminal receives PDSCH in any of PDSCH candidate receptions 4 or 5, its corresponding ACK / NACK information is mapped to a different bit. For example, Figure 2The example shown uses single-codeword transmission, where one PDSCH carries only one TB and corresponds to 1 bit of feedback information. This time slot corresponds to 2 ACK / NACK bits in the type-1 codebook. One of these ACK / NACK bits is used to provide feedback on the PDSCH received at any one of PDSCH candidate reception opportunities 1, 2, and 3 within a time slot (i.e., at one time). The other bit is used to provide feedback on the PDSCH received at any one of PDSCH candidate reception opportunities 4 and 5 within the same time slot (i.e., at another time). In this embodiment, a candidate reception opportunity set may include multiple consecutive PDSCH candidate reception opportunities, or a candidate reception opportunity set may include multiple non-consecutive PDSCH candidate reception opportunities where the time interval between two adjacent PDSCH candidate reception opportunities is less than or equal to a certain threshold. PDSCH candidate reception opportunities can also be called PDSCH candidate reception resources, or simply candidate opportunities, reception opportunities, candidate resources, or candidate opportunities.

[0063] The Type-2 feedback codebook primarily addresses the feedback overhead issue. Specifically, within the set of PDCCH monitoring occasions, it determines the number of ACK / NACK messages based on the actual number of PDSCHs scheduled. The DCI for scheduling PDSCH transmissions introduces a Downlink Assignment Index (DAI) field to indicate the total number of PDSCHs scheduled up to the current PDSCH.

[0064] Figure 3 It is the Type-2 feedback codebook provided in the embodiments of this application.

[0065] like Figure 3 As shown, the Physical Downlink Control Channel (PDSCH) monitoring opportunity set includes 8 time slots. If the terminal receives PDSCH in only 4 of these time slots, then the terminal needs to feed back 4 bits of information. The drawback of this method is that when the terminal does not receive part of the PDSCH sent by the base station (such as the last PDSCH), there is a discrepancy between the base station and the UE's understanding of the actual number of scheduled PDSCHs, resulting in an inconsistency in the understanding of the amount of feedback information.

[0066] To support URLLC transmission, NR R16 introduces high and low priorities for uplink channels at the physical layer. Specifically, network devices can be configured to provide terminal devices with two feedback codebooks, one for carrying acknowledgment (ACK) or negative acknowledgment (NACK) feedback information of different priorities, and the other for carrying ACK / NACK information. Priority index 0 represents low priority, and priority index 1 represents high priority. The uplink channel carrying ACK / NACK information has the same priority as the feedback codebook it carries, and other uplink channels will also correspond to priority index 0 or priority index 1. Different priority channels have different transmission performance requirements, including reliability and latency. In the NR R16 system, when uplink channels of different priorities overlap in the time domain, only the high-priority channel is transmitted, and the low-priority channel is discarded. However, while transmitting only the high-priority channel ensures its transmission, it cannot guarantee the transmission of low-priority channels, reducing system transmission efficiency and reliability.

[0067] In NR R17, to reduce the impact of discarding low-priority uplink channels on system efficiency, it supports the multiplexing of information carried in overlapping channels with different priorities. During multiplexing, the transmission performance requirements (reliability, latency) of high-priority information (information carried in high-priority channels) must be guaranteed. However, significant modifications to the transmission process of high-priority information during multiplexing will reduce its reliability. Therefore, how to ensure the reliability of high-priority feedback information while maintaining system efficiency during the multiplexing of information with different priorities is a pressing technical problem that needs to be solved in this field.

[0068] Based on this, embodiments of this application provide a wireless communication method and device that, while supporting the multiplexing and transmission of information of different priorities, can ensure the reliability of high-priority feedback information while also taking into account system efficiency.

[0069] Figure 4 This is a schematic flowchart of a wireless communication method 200 provided in an embodiment of this application. The method 200 can be executed by a terminal device, for example, the method 200 can be executed by... Figure 1 The terminal device shown executes this.

[0070] S210, when the feedback resources used to carry the first feedback codebook overlap with the feedback resources used to carry the second feedback codebook, a third feedback codebook is used to transmit all the information in at least one first feedback information and part or all of the information in at least one second feedback information; the priority of the first feedback codebook is different from that of the second feedback codebook, the first feedback codebook includes the at least one first feedback information, the second feedback codebook includes the at least one second feedback information, and the size of the third feedback codebook is the same as the size of the first feedback codebook. In other words, the number of bits included in the first feedback codebook and the number of bits included in the third feedback codebook are the same.

[0071] In this embodiment, it is assumed that the terminal is configured to support a first feedback codebook and a second feedback codebook, and the priority of the first feedback codebook is higher or lower than the priority of the second feedback codebook. As an example, taking the first feedback codebook as a high-priority codebook, the first codebook is used to feed back high-priority ACK / NACK information (i.e., the codebook only includes high-priority ACK / NACK information, or the codebook includes high-priority ACK / NACK information and placeholder information NACK), and the uplink control channel carrying the first feedback codebook has a high priority, i.e., the priority information is 1 (priority index = 1); taking the second feedback codebook as a low-priority codebook, the second codebook is used to feed back low-priority ACK / NACK information (i.e., the codebook only includes low-priority ACK / NACK information, or the codebook includes low-priority ACK / NACK information and placeholder information NACK), and the uplink control channel carrying the second feedback codebook has a low priority, i.e., the priority information is 0 (priority index = 0).

[0072] Based on the above technical solutions, when the feedback resources used to carry the first feedback codebook overlap with those used to carry the second feedback codebook, using the third feedback codebook to transmit all information in at least one first feedback message and part or all information in at least one second feedback message can avoid completely discarding the at least one second feedback message, thus improving system efficiency. Furthermore, since the size of the third feedback codebook is the same as the size of the first feedback codebook, it is advantageous to generate the third feedback codebook using the same method as generating the first feedback codebook, avoiding significant modifications to the transmission process of the at least one first feedback message and ensuring the reliability of the at least one first feedback message.

[0073] It should be noted that the feedback resources involved in the embodiments of this application can be any time-domain resource used to send feedback information. For example, Physical Uplink Control Channel (PUCCH) resources or Physical Uplink Shared Channel (PUSCH) resources.

[0074] In some embodiments, the bit position occupied by the at least one first feedback information in the third feedback codebook is the same as the bit position occupied by the at least one first feedback information in the first feedback codebook.

[0075] In some embodiments, some or all of the information in the at least one second feedback information is located in bit positions in the third feedback codebook that are not occupied by the at least one first feedback information. In other words, the bit positions occupied by some or all of the information in the at least one second feedback information in the third feedback codebook include the bit positions not occupied by the at least one first feedback information in the third feedback codebook. In one implementation, the unoccupied bit positions in the third feedback codebook are used to carry some or all of the information in the at least one second feedback information; in another implementation, all the unoccupied bit positions in the third feedback codebook are used to carry some or all of the information in the at least one second feedback information.

[0076] In some embodiments, the feedback resources used to carry the third feedback codebook are the same as the feedback resources used to carry the first feedback codebook. In one implementation, the resources of the uplink channel used to carry the third feedback codebook are the same as the resources of the uplink channel used to carry the first feedback codebook. The resources of the uplink channel used to carry the first feedback codebook can be semi-statically configured resources or dynamically configured resources. If the first feedback codebook is a Type-1 feedback codebook, the resources of the uplink channel used to carry the first feedback codebook are semi-static resources; if the first feedback codebook is a Type-2 feedback codebook, the resources of the uplink channel used to carry the first feedback codebook are dynamically configured resources.

[0077] In some embodiments, the first feedback codebook has a higher priority than the second feedback codebook.

[0078] In some embodiments, the first feedback codebook is a Type-1 feedback codebook.

[0079] In some embodiments, the second feedback codebook is a Type-1 feedback codebook or a Type-2 feedback codebook.

[0080] In some embodiments, the first feedback codebook corresponds to the first physical downlink shared channel (PDSCH) candidate reception opportunity set (The set of PDCCH monitoring occasions), and the at least one first feedback information is the feedback information corresponding to at least one first PDSCH received within the first PDSCH candidate reception opportunity set.

[0081] In some embodiments, the second feedback codebook corresponds to a second PDSCH candidate reception opportunity set, and the at least one second feedback information is the feedback information corresponding to at least one second PDSCH received within the second PDSCH candidate reception opportunity set.

[0082] In some embodiments, the at least one second feedback information is feedback information for at least one second PDSCH; the third feedback codebook includes the second feedback information corresponding to one of the at least one second PDSCHs received within the first PDSCH candidate reception opportunity set; or, the third feedback codebook includes the second feedback information corresponding to one of the at least one second PDSCHs, wherein the end symbol of the second PDSCH is located within the first PDSCH candidate reception opportunity set; or, the third feedback codebook includes the second feedback information corresponding to one of the at least one second PDSCHs, wherein the end symbol of the second PDSCH is located within one PDSCH candidate resource opportunity within the first PDSCH candidate reception opportunity set.

[0083] It should be noted that the third feedback codebook includes the second feedback information corresponding to one of the at least one second PDSCH received within the first PDSCH candidate reception opportunity set. This can be understood as: the third feedback codebook includes at least the second feedback information corresponding to one of the at least one second PDSCH received within the first PDSCH candidate reception opportunity set; or, the third feedback codebook may include the second feedback information corresponding to multiple second PDSCHs among the at least one second PDSCH received within the first PDSCH candidate reception opportunity set. This application embodiment does not limit this aspect.

[0084] In some embodiments, the method 200 may further include:

[0085] Based on the first PDSCH candidate reception opportunity occupied by the second PDSCH in the first PDSCH candidate reception opportunity set, determine the bit position occupied by the second feedback information corresponding to the second PDSCH in the third feedback codebook.

[0086] In other words, the bit position occupied by the second feedback information corresponding to the second PDSCH in the third feedback codebook is determined based on the first PDSCH candidate reception opportunity occupied by the second PDSCH in the first PDSCH candidate reception opportunity set.

[0087] In one implementation, it is assumed that the first feedback codebook is configured as a Type-1 codebook, and the second feedback codebook is configured as either Type-1 or Type-2 (or is not limited by codebook type). If an uplink channel (uplink control channel PUCCH or uplink shared channel PUSCH) transmitting the first feedback codebook overlaps (time-domain overlap) with an uplink channel transmitting the second feedback codebook, which can be complete or partial overlap, the terminal transmits a special first feedback codebook (i.e., a third feedback codebook). This third feedback codebook includes feedback information corresponding to all PDSCHs received on a set of M_(A,c) occasions for candidate PDSCH receptions (the PDSCHs end within this set of candidate PDSCH reception opportunities), specifically high-priority ACK / NACK information and low-priority ACK / NACK information. Alternatively, the third feedback codebook corresponds to a set of candidate PDSCH reception opportunities. The terminal abandons the transmission of low-priority ACK / NACK information received within the set of candidate PDSCH reception opportunities in the second feedback codebook.

[0088] Figure 5 This is a schematic block diagram illustrating at least one first feedback information and at least one second feedback information provided in the embodiments of this application.

[0089] like Figure 5As shown, the first feedback codebook is transmitted via HP PUCCH (high priority PUCCH). The first PDSCH candidate reception opportunity set corresponding to the first feedback codebook includes four PDSCH candidate reception opportunities, namely PDSCH candidate reception opportunities 1 to 4. Each PDSCH candidate reception opportunity is a sub-slot. The first feedback codebook includes 4 bits (assuming the maximum number of PDSCH codewords is 1). If the terminal receives PDSCH in both PDSCH candidate reception opportunities 1 and 3 in the first PDSCH candidate reception opportunity set, and the corresponding ACK / NACK is of high priority, then the first feedback codebook is {b1, NACK, b2, NACK}. Furthermore, the second feedback codebook is transmitted via LP PUCCH (low priority PUCCH). The second PDSCH candidate reception opportunity set corresponding to the second feedback codebook includes three PDSCH candidate reception opportunities, namely PDSCH candidate reception opportunities 1 to 3. Each PDSCH candidate reception opportunity is a time slot, meaning the second PDSCH candidate reception opportunity set includes time slots 1 to 3. The terminal receives PDSCH 3 and PDSCH 4 at PDSCH candidate reception opportunities 1 and 2 respectively, and their corresponding ACK / NACK information is of low priority. In one implementation, if the second feedback codebook is configured as a Type-2 codebook, then the second feedback codebook is {b3, b4}. In another implementation, if the second codebook is configured as a Type-1 codebook, then the second feedback codebook includes 3 bits (assuming the maximum number of PDSCH codewords is 1), specifically, the second feedback codebook is {b3, b4, NACK}. Where bi is the ACK / NACK information corresponding to PDSCH i, and the value of i is a positive integer.

[0090] It should be noted that each of the above-mentioned PDSCH candidate reception opportunities in the embodiments of this application may also be a sub-slot or a single slot, etc.

[0091] In this embodiment, a third feedback codebook of the same size as the first feedback codebook can be used to transmit all the feedback information in the first feedback codebook and part of the feedback information in the second feedback codebook. For example, combined with Figure 5In this case, the HP PUCCH and LP PUCCH overlap. The terminal sends a special first feedback codebook (i.e., the third feedback codebook) through the HP PUCCH. The third feedback codebook may include {b1, b4, b2, NACK}. That is, for PDSCH 4, which corresponds to low-priority ACK / NACK information, if its ending position belongs to the first PDSCH candidate reception opportunity set (i.e., PDSCH candidate reception opportunities 1 to 4), its ACK / NACK information is multiplexed with high-priority ACK / NACK information to obtain a third feedback codebook of the same size as the first feedback codebook for transmission. In addition, LP PDSCH 3, which does not fall within the first PDSCH candidate reception opportunity set (i.e., PDSCH candidate reception opportunities 1 to 4), does not provide ACK / NACK feedback.

[0092] In this embodiment, a third feedback codebook of the same size as the first feedback codebook is used to transmit all feedback information in the first feedback codebook and part of the feedback information in the second feedback codebook. This can, to some extent, prevent LP ACK / NACK from being discarded, thus improving system efficiency. Furthermore, it avoids significant modifications to the HP PUCCH transmission process, ensuring the reliability of HP PUCCH transmission.

[0093] It should be noted that when the first PDSCH candidate reception opportunity set and the second PDSCH candidate reception opportunity set overlap, the terminal device may receive a first PDSCH and a second PDSCH simultaneously within one PDSCH candidate reception opportunity in the first PDSCH candidate reception opportunity set.

[0094] In some embodiments, if a first PDSCH and a second PDSCH are received within one PDSCH candidate reception opportunity in the first PDSCH candidate reception opportunity set, the third feedback codebook includes the first feedback information corresponding to the first PDSCH.

[0095] For example, the third feedback codebook includes the first feedback information corresponding to the first PDSCH and the second feedback information corresponding to the second PDSCH. Alternatively, the third feedback codebook may include the first feedback information corresponding to the first PDSCH but not the second feedback information corresponding to the second PDSCH.

[0096] For example, in a Type-1 codebook, a PDSCH candidate receive opportunity corresponds to 1 or 2 ACK / NACK bits (depending on the maximum number of codewords in a PDSCH). If both LP PDSCH and HP PDSCH ending symbols exist within a PDSCH candidate receive opportunity, the HP ACK / NACK information is mapped to the Type-1 feedback codebook, and the LP ACK / NACK is not transmitted.

[0097] Figure 6 This is another schematic block diagram illustrating at least one first feedback information and at least one second feedback information provided in the embodiments of this application.

[0098] like Figure 6 As shown, for HP PDSCH candidate reception opportunity 2, the end symbols of PDSCH 1 and PDSCH 4 are within one PDSCH candidate reception opportunity. In this case, only the feedback information of PDSCH 4 is mapped into the codebook, so the Type-1 codebook is {b3, b4, b2}, where bi is the ACK / NACK information corresponding to PDSCH 4. In this embodiment, a third feedback codebook of the same size as the first feedback codebook is used to transmit all the feedback information in the first feedback codebook and some or all of the feedback information in the second feedback codebook. This can, to a certain extent, prevent LP ACK / NACK from being discarded, improving system efficiency. Furthermore, it avoids significant modifications to the HP PUCCH transmission process, ensuring the reliability of HP PUCCH transmission.

The following will be combined with Figure 7 The method according to embodiments of this application is described from the perspective of a network device. Figure 7 This is a schematic flowchart of the wireless communication method 300 provided in an embodiment of this application. Figure 7 As shown, the method 300 may include:

[0100] S310, when the feedback resources used to carry the first feedback codebook and the feedback resources used to carry the second feedback codebook overlap, a third feedback codebook is used to receive all the information in at least one first feedback information and part or all of the information in at least one second feedback information; the priority of the first feedback codebook is different from the priority of the second feedback codebook, the first feedback codebook includes the at least one first feedback information, the second feedback codebook includes the at least one second feedback information, and the size of the third feedback codebook is the same as the size of the first feedback codebook.

[0101] In some embodiments, the bit position occupied by the at least one first feedback information in the third feedback codebook is the same as the bit position occupied by the at least one first feedback information in the first feedback codebook.

[0102] In some embodiments, some or all of the information in the at least one second feedback information is located in the bit positions in the third feedback codebook where the at least one first feedback information is not occupied.

[0103] In some embodiments, the feedback resources used to carry the third feedback codebook are the same as the feedback resources used to carry the first feedback codebook.

[0104] In some embodiments, the first feedback codebook has a higher priority than the second feedback codebook.

[0105] In some embodiments, the first feedback codebook is a Type-1 feedback codebook.

[0106] In some embodiments, the first feedback codebook corresponds to the first physical downlink shared channel (PDSCH) candidate reception opportunity set (The set of PDCCH monitoring occasions), and the at least one first feedback information is the feedback information corresponding to at least one first PDSCH received within the first PDSCH candidate reception opportunity set.

[0107] In some embodiments, the second feedback codebook corresponds to a second PDSCH candidate reception opportunity set, and the at least one second feedback information is the feedback information corresponding to at least one second PDSCH received within the second PDSCH candidate reception opportunity set.

[0108] In some embodiments, the at least one second feedback information is feedback information for at least one second PDSCH; the third feedback codebook includes the second feedback information corresponding to one of the at least one second PDSCHs received within the first PDSCH candidate reception opportunity set; or, the third feedback codebook includes the second feedback information corresponding to one of the at least one second PDSCHs, wherein the end symbol of the second PDSCH is located within the first PDSCH candidate reception opportunity set; or, the third feedback codebook includes the second feedback information corresponding to one of the at least one second PDSCHs, wherein the end symbol of the second PDSCH is located within one PDSCH candidate resource opportunity within the first PDSCH candidate reception opportunity set.

[0109] It should be noted that the third feedback codebook includes the second feedback information corresponding to one of the at least one second PDSCH received within the first PDSCH candidate reception opportunity set. This can be understood as: the third feedback codebook includes at least the second feedback information corresponding to one of the at least one second PDSCH received within the first PDSCH candidate reception opportunity set; that is, the third feedback codebook may include the second feedback information corresponding to multiple second PDSCHs among the at least one second PDSCH received within the first PDSCH candidate reception opportunity set. This application embodiment does not limit this aspect.

[0110] In some embodiments, the method 300 may further include:

[0111] Based on the first PDSCH candidate reception opportunity occupied by the second PDSCH in the first PDSCH candidate reception opportunity set, determine the bit position occupied by the second feedback information corresponding to the second PDSCH in the third feedback codebook.

[0112] In some embodiments, if a first PDSCH and a second PDSCH are received within one PDSCH candidate reception opportunity in the first PDSCH candidate reception opportunity set, the third feedback codebook includes the first feedback information corresponding to the first PDSCH.

[0113] In some embodiments, the second feedback codebook is a Type-1 feedback codebook or a Type-2 feedback codebook.

[0114] It should be understood that the steps in method 300 can refer to the corresponding steps in method 200, and for the sake of brevity, they will not be repeated here.

[0115] In the foregoing, whether to transmit the third feedback codebook is determined by the terminal or network device based on whether the feedback resources used to carry the first feedback codebook and the feedback resources used to carry the second feedback codebook overlap. However, the embodiments of this application are not limited to this. This application also provides a wireless communication method that instructs a terminal device through a network device whether to transmit the third feedback codebook, thereby implementing a scheme for multiplexing transmission using the third feedback codebook.

[0116] Figure 8 This is a schematic flowchart of a wireless communication method 400 provided in an embodiment of this application. The method 400 can be interactively executed by a terminal device and a network device. Figure 8 The terminal device shown can be, for example, Figure 1 The terminal device shown, Figure 8 The network device shown can be, for example, Figure 1The access network equipment shown.

[0117] like Figure 8 As shown, the method 400 may include:

[0118] S410, Receive first information, the first information being configured for the terminal device to transmit feedback information using a first feedback codebook and a second feedback codebook, wherein the priority of the first feedback codebook is different from the priority of the second feedback codebook, the first feedback codebook includes at least one first feedback information, and the second feedback codebook includes at least one second feedback information; it should be noted that the first information may be Radio Resource Control (RRC) signaling or Media Access Control (MAC) control element (CE), and this embodiment of the application does not specifically limit it in this way.

[0119] S420, Receive first indication information. The first indication information is used to indicate whether to transmit feedback information using the first feedback codebook or the third feedback codebook in a time unit. The third feedback codebook includes all information from the at least one first feedback information and part or all information from the at least one second feedback information. The size of the third feedback codebook is the same as the size of the first feedback codebook. It should be noted that the first indication information can also be understood as: the first indication information is used to indicate whether the terminal device should transmit feedback information of one priority or two priorities, or the first indication information is used to indicate whether the terminal device should use the third feedback codebook to transmit feedback information. It should be noted that the first indication information can be RRC signaling or MAC CE; this application embodiment does not specifically limit this. The time unit can be a set of PDSCH candidate reception opportunities or a time period with a certain threshold length, which can be predefined or network configured. For example, the time unit can include at least one time slot or at least one symbol.

[0120] In this embodiment, it is assumed that the terminal is configured to support a first feedback codebook and a second feedback codebook, and the priority of the first feedback codebook is higher or lower than the priority of the second feedback codebook. As an example, taking the first feedback codebook as a high-priority codebook, the first codebook is used to feed back high-priority ACK / NACK information (i.e., the codebook only includes high-priority ACK / NACK information or high-priority ACK / NACK information and placeholder information NACK), and the uplink control channel carrying the first feedback codebook has a high priority, i.e., the priority information is 1 (priority index = 1); taking the second feedback codebook as a low-priority codebook, the second codebook is used to feed back low-priority ACK / NACK information (i.e., the codebook only includes low-priority ACK / NACK information or low-priority ACK / NACK information and placeholder information NACK), and the uplink control channel carrying the second feedback codebook has a low priority, i.e., the priority information is 0 (priority index = 0).

[0121] Based on the above technical solutions, when the feedback resources used to carry the first feedback codebook overlap with those used to carry the second feedback codebook, using a third feedback codebook to transmit all information in at least one first feedback message and part or all information in at least one second feedback message can, to a certain extent, prevent the second feedback information from being discarded and improve system efficiency. Furthermore, since the size of the third feedback codebook is the same as the size of the first feedback codebook, it is equivalent to generating the third feedback codebook in the same way as generating the first feedback codebook, avoiding significant modifications to the transmission process of the at least one first feedback message and ensuring the reliability of the at least one first feedback message.

[0122] In some embodiments, the bit position occupied by the at least one first feedback information in the third feedback codebook is the same as the bit position occupied by the at least one first feedback information in the first feedback codebook.

[0123] In some embodiments, some or all of the information in the at least one second feedback information is located in bit positions not occupied by the at least one first feedback information in the third feedback codebook. In one implementation, some bit positions not occupied by the at least one first feedback information in the third feedback codebook are used to carry the second feedback information; in another implementation, all bit positions not occupied by the at least one first feedback information in the third feedback codebook are used to carry the second feedback information.

[0124] In some embodiments, the feedback resources used to carry the third feedback codebook are the same as the feedback resources used to carry the first feedback codebook. In one implementation, the resources of the uplink channel used to carry the third feedback codebook are the same as the resources of the uplink channel used to carry the first feedback codebook. The resources of the uplink channel used to carry the first feedback codebook can be semi-static resources or dynamically configured resources. If the first feedback codebook is a Type-1 feedback codebook, the resources of the uplink channel used to carry the first feedback codebook are semi-static resources; if the first feedback codebook is a Type-2 feedback codebook, the resources of the uplink channel used to carry the first feedback codebook are dynamically configured resources.

[0125] In some embodiments, the priority of the first feedback codebook is higher than the priority of the second feedback codebook, or the priority of the first feedback codebook is lower than the priority of the second feedback codebook.

[0126] In some embodiments, the first feedback codebook and the third feedback codebook are Type-1 codebooks.

[0127] In some embodiments, the first feedback codebook corresponds to the first physical downlink shared channel (PDSCH) candidate reception opportunity set (The set of PDCCH monitoring occasions), and the at least one first feedback information is the feedback information corresponding to at least one first PDSCH received within the first PDSCH candidate reception opportunity set.

[0128] In some embodiments, the second feedback codebook corresponds to a second PDSCH candidate reception opportunity set, and the at least one second feedback information is the feedback information corresponding to at least one second PDSCH received within the second PDSCH candidate reception opportunity set.

[0129] In some embodiments, the at least one second feedback information is feedback information for at least one second PDSCH; the third feedback codebook includes the second feedback information corresponding to one of the at least one second PDSCHs received within the first PDSCH candidate reception opportunity set; or, the third feedback codebook includes the second feedback information corresponding to one of the at least one second PDSCHs, wherein the end symbol of the second PDSCH is located within the first PDSCH candidate reception opportunity set; or, the third feedback codebook includes the second feedback information corresponding to one of the at least one second PDSCHs, wherein the end symbol of the second PDSCH is located within one PDSCH candidate resource opportunity within the first PDSCH candidate reception opportunity set.

[0130] It should be noted that the third feedback codebook includes the second feedback information corresponding to one of the at least one second PDSCH received within the first PDSCH candidate reception opportunity set. This can be understood as: the third feedback codebook includes at least the second feedback information corresponding to one of the at least one second PDSCH received within the first PDSCH candidate reception opportunity set; that is, the third feedback codebook may include the second feedback information corresponding to multiple second PDSCHs among the at least one second PDSCH received within the first PDSCH candidate reception opportunity set. This application embodiment does not limit this aspect.

[0131] In some embodiments, the method 400 may further include:

[0132] Based on the first PDSCH candidate reception opportunity occupied by the second PDSCH in the first PDSCH candidate reception opportunity set, determine the bit position occupied by the second feedback information corresponding to the second PDSCH in the third feedback codebook.

[0133] In some embodiments, if a first PDSCH and a second PDSCH are received within one PDSCH candidate reception opportunity in the first PDSCH candidate reception opportunity set, the third feedback codebook includes either the first feedback information corresponding to the first PDSCH or the feedback information with higher priority between the first feedback information corresponding to the first PDSCH and the second feedback information corresponding to the second PDSCH.

[0134] In some embodiments, the method 400 may further include:

[0135] The terminal device receives a second indication message sent by the network device, the second indication message being used to instruct the transmission of feedback information using a Type-1 feedback codebook within the time unit. In other words, the second indication message is used to instruct the terminal device to send a Type-1 feedback codebook.

[0136] In one implementation, the terminal device receives a DCI sent by the network device, the DCI including the second indication information. For example, the terminal device receives the DCI indicating an HP PUCCH resource, and the DCI is also used to indicate the transmission of a Type-1 codebook. Optionally, the DCI may also include the first indication information, based on which the terminal device can determine the Type-1 codebook, i.e., the third feedback codebook, based on the DCI.

[0137] In one implementation, it is assumed that the first feedback codebook is configured as a Type-1 codebook, and the second feedback codebook is configured as either Type-1 or Type-2 (or is not limited by codebook type). If an uplink channel (uplink control channel PUCCH or uplink shared channel PUSCH) transmitting the first feedback codebook overlaps (time-domain overlap) with an uplink channel transmitting the second feedback codebook, which can be complete or partial overlap, the terminal transmits a special first feedback codebook (i.e., a third feedback codebook). This third feedback codebook includes feedback information corresponding to all PDSCHs received on a set of M_(A,c) occasions for candidate PDSCH receptions (the PDSCHs end within this set of candidate PDSCH reception opportunities), specifically high-priority ACK / NACK information and low-priority ACK / NACK information. Alternatively, the third feedback codebook corresponds to a set of candidate PDSCH reception opportunities. The terminal abandons the transmission of low-priority ACK / NACK information received within the set of candidate PDSCH reception opportunities in the second feedback codebook.

[0138] Figure 9 This is a schematic block diagram illustrating at least one first feedback information and at least one second feedback information provided in the embodiments of this application.

[0139] like Figure 9As shown, the first feedback codebook is transmitted via HP PUCCH (high priority PUCCH). The first PDSCH candidate reception opportunity set corresponding to the first feedback codebook includes four PDSCH candidate reception opportunities, namely PDSCH candidate reception opportunities 1 to 4. Each PDSCH candidate reception opportunity is a sub-slot. The first feedback codebook includes 4 bits (assuming the maximum number of PDSCH codewords is 1). If the terminal receives PDSCH in both PDSCH candidate reception opportunities 1 and 3 in the first PDSCH candidate reception opportunity set, and the corresponding ACK / NACK is of high priority, then the first feedback codebook is {b1, NACK, b2, NACK}. Furthermore, the second feedback codebook is transmitted via LP PUCCH (low priority PUCCH). The second PDSCH candidate reception opportunity set corresponding to the second feedback codebook includes three PDSCH candidate reception opportunities, namely PDSCH candidate reception opportunities 1 to 3. Each PDSCH candidate reception opportunity is a time slot, meaning the second PDSCH candidate reception opportunity set includes time slots 1 to 3. The terminal receives PDSCH 3 and PDSCH 4 at PDSCH candidate reception opportunities 1 and 2 respectively, and their corresponding ACK / NACK information is of low priority. In one implementation, if the second feedback codebook is configured as a Type-2 codebook, then the second feedback codebook is {b3, b4}. In another implementation, if the second codebook is configured as a Type-1 codebook, then the second feedback codebook includes 3 bits (assuming the maximum number of PDSCH codewords is 1), specifically, the second feedback codebook is {b3, b4, NACK}. Where bi is the ACK / NACK information corresponding to PDSCH i.

[0140] In one implementation, the first feedback codebook is a high-priority feedback codebook, meaning the priority of the first feedback codebook is higher than the priority of the second feedback codebook. Based on this, combined with Figure 9 For example, if the first indication information is used to indicate that feedback information is transmitted using the first feedback codebook in a time unit, the first feedback codebook may include: receiving high-priority ACK / NACK information corresponding to PDSCH in PDSCH candidate reception opportunities 1 to 4: that is, the first feedback codebook is {b1,NACK,b2,NACK}; if the first indication information is used to indicate that feedback information is transmitted using the third feedback codebook in a time unit, the third feedback codebook may include: receiving high-priority and low-priority ACK / NACK information corresponding to PDSCH in PDSCH candidate reception opportunities 1 to 4, that is, the third feedback codebook is {b1,b4,b2,NACK}.

[0141] In this embodiment, the network device can flexibly control the terminal to multiplex ACK / NACK information of different priorities for transmission, avoiding the discarding of low-priority ACK / NACK information and improving system efficiency.

[0142] In another implementation, the first feedback codebook is a low-priority feedback codebook, meaning its priority is lower than that of the second feedback codebook. Based on this, combined with... Figure 9 For example, if the first indication information is used to indicate that feedback information is transmitted using the first feedback codebook in a time unit, the first feedback codebook may include: receiving low-priority ACK / NACK information corresponding to PDSCH in the corresponding PDSCH candidate reception opportunity; for example, if the first feedback codebook is configured as a Type-2 codebook, then the first feedback codebook is {b3, b4}; or, if the first codebook is configured as a Type-1 codebook, then the first feedback codebook includes 3 bits (assuming the maximum number of PDSCH codewords is 1), specifically, the second feedback codebook is {b3, b4, NACK}. Where bi is the ACK / NACK information corresponding to PDSCH i. If the first indication information is used to indicate that feedback information is transmitted using the third feedback codebook in a time unit, the third feedback codebook may include: receiving high-priority and low-priority ACK / NACK information corresponding to PDSCH in the corresponding PDSCH candidate reception opportunity, that is, the third feedback codebook is {b3, b4, b2}.

[0143] In this embodiment, the network device can flexibly control the terminal to multiplex ACK / NACK information of different priorities for transmission, and retransmit high-priority ACK / NACK information (high-priority ACK / NCACK information itself also has a corresponding PUCCH) through LP PUCCH retransmission, thereby improving the reliability of high-priority ACK / NACK information.
