Description

Wireless communication method and device

technical field

The embodiments of the present application relate to the field of communication, and more particularly, to wireless communication methods and devices.

Background technique

In the New Radio (NR) version 16 (Rel-16), high and low priorities are introduced at the physical layer for the uplink channel to better support ultra-reliable low-latency communication (Ultra-reliable low latency, URLLC) business. Specifically, the network device may configure two feedback codebooks for the terminal device, which are respectively used to carry positive acknowledgment (Acknowledgement, ACK) feedback information or negative acknowledgment (Negative Acknowledgement, NACK) feedback information of different priorities, and pass the priority index. (priority index) 0 means low priority, priority index 1 means high priority. The priority of the uplink channel carrying the ACK/NACK information is the same as the priority of the feedback codebook carried therein, and the corresponding other uplink channels will also correspond to priority index 0 or priority index 1. Different priority channels have different transmission performance requirements, wherein the transmission performance includes reliability and delay.

In the NR R16 system, when uplink channels with different priorities overlap in the time domain, only high-priority channels are transmitted, and low-priority channels are discarded. However, although only the high-priority channel can be transmitted, the transmission of the high-priority channel can be preferentially guaranteed, but the transmission of the low-priority channel cannot be guaranteed, which reduces the transmission efficiency and reliability of the system.

Therefore, for the transmission method of feedback information, a wireless communication method is urgently needed in the art to improve the transmission efficiency and reliability of the system.

It should be understood that, in the embodiments of the present application, a device having a communication function in the network/system can be referred to as a communication device. Taking the communication system 100 shown in FIG. 1 as an example, the communication device may include a network device 120 and a terminal device 110 with a communication function, and the network device 120 and the terminal device 110 may be the devices described above, which will not be repeated here; The communication device may further include other devices in the communication system 100, such as other network entities such as a network controller and a mobility management entity, which are not limited in this embodiment of the present application.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" in this article is only an association relationship to describe the associated objects, indicating that there can be three kinds of relationships, for example, A and/or B, it can mean that A exists alone, A and B exist at the same time, and A and B exist independently B these three cases. In addition, the character "/" in this text generally indicates that the related objects are an "or" relationship.

In NR R15, two ACK/NACK information generation methods are supported: semi-static HARQ-ACK codebook and dynamic HARQ-ACK codebook. The semi-static HARQ feedback codebook is also called Type-1 feedback codebook, and the dynamic HARQ feedback codebook is also called Type-2 feedback codebook.

The Type-1 feedback codebook adopts a semi-static way to determine the number of bits of ACK/NACK feedback information corresponding to PDSCH, that is, the number of ACK/NACK bits included in the feedback codebook does not depend on the actual received PDSCH number, but is based on the semi-static The statically configured downlink resources available for PDSCH transmission (ie, the maximum number of PDSCHs that can be received) are determined. The advantage of this method is that it can avoid the ambiguity between the terminal and the base station in the understanding of the ACK/NACK feedback codebook size caused by the terminal not receiving part of the PDSCH, so that the base station can correctly receive the feedback information sent by the terminal. However, the disadvantage of this method is that the feedback overhead is relatively large, that is, all downlink resources that may transmit PDSCH must have reserved feedback information bits.

As shown in FIG. 2, since the terminal only receives at most one PDSCH at the same time in one carrier, that is, one time slot shown in FIG. 2 may be a candidate receiver opportunity set (The set of PDCCH monitoring occasions), the one The PDSCH candidate reception opportunities (occasions for candidate PDSCH receptions) 1-5 that may be included in the candidate reception opportunity set. Among them, PDSCH candidate reception opportunities 1 and PDSCH

candidate reception opportunities

2 and 3 will not be transmitted at the same time, and PDSCH candidate reception opportunities 4 and 5 will not be transmitted at the same time. If corresponding feedback information bits are reserved for PDSCH candidate receiver opportunities 1-5 in the type-1 codebook, there is bound to be feedback information redundancy. On the other hand, if multiple PDSCH candidate receivers within the same moment share one feedback information bit, the feedback overhead can be reduced. That is, the terminal receives PDSCH in any one of PDSCH

candidate reception opportunities

1, 2, and 3, and its corresponding ACK/NACK information is mapped to one bit, and the terminal receives PDSCH in any one of PDSCH candidate reception opportunities 4 and 5. When PDSCH is received, its corresponding ACK/NACK information is mapped to another bit. For example, in the example shown in Figure 2, a single codeword transmission is taken as an example, that is, a PDSCH only carries one TB and corresponds to 1 bit of feedback information, and this time slot corresponds to 2 ACK/NACK bits in the type-1 codebook, namely Can. Among them, one of the two ACK/NACK bits can be used to feed back the PDSCH received in any one of PDSCH

candidate receiver opportunities

1, 2, and 3 in one time slot (that is, at one time), and the other One bit is available for feeding back the PDSCH received in any one of PDSCH candidate receiver opportunities 4 and 5 in the one time slot (ie, another time instant). In this embodiment, one candidate reception opportunity set may include multiple consecutive PDSCH candidate reception opportunities, or, one candidate reception opportunity set may include multiple discontinuous PDSCH candidate reception opportunities and the interval between two adjacent PDSCH candidate reception opportunities The time interval is less than or equal to a certain threshold. PDSCH candidate reception opportunities may also be referred to as PDSCH candidate reception resources, and may also be simply referred to as candidate opportunities, reception opportunities, candidate resources, or candidate opportunities.

The Type-2 feedback codebook mainly solves the feedback overhead problem, that is, within the physical downlink control channel monitoring opportunity set (The set of PDCCH monitoring occasions), the number of ACK/NACK information is determined according to the number of PDSCHs actually scheduled. Specifically, a downlink assignment index (Downlink assignment index, DAI) information field is introduced into the DCI for scheduling PDSCH transmission to indicate the total number of PDSCHs that have been scheduled up to the currently scheduled PDSCH.

FIG. 3 is a Type-2 feedback codebook provided by an embodiment of the present application.

As shown in FIG. 3 , the physical downlink control channel monitoring opportunity set includes 8 time slots, and the terminal only receives the PDSCH in 4 time slots, so the terminal needs to feed back 4-bit information. The disadvantage 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 problem that the base station and the UE have inconsistent understanding of the number of PDSCHs actually scheduled, resulting in inconsistent understanding of the quantity of feedback information.

In order to support URLLC transmission, NR R16 introduces high and low priority at the physical layer for the uplink channel. Specifically, the network device may configure two feedback codebooks for the terminal device, which are respectively used to carry positive acknowledgment (Acknowledgement, ACK) feedback information or negative acknowledgment (Negative Acknowledgement, NACK) feedback information of different priorities, and pass the priority index. (priority index) 0 means low priority, priority index 1 means high priority. The priority of the uplink channel carrying the ACK/NACK information is the same as the priority of the feedback codebook carried therein, and the corresponding other uplink channels will also correspond to priority index 0 or priority index 1. Different priority channels have different transmission performance requirements, wherein the transmission performance includes reliability and delay. In the NR R16 system, when uplink channels with different priorities overlap in the time domain, only high-priority channels are transmitted, and low-priority channels are discarded. However, although only the high-priority channel can be transmitted, the transmission of the high-priority channel can be preferentially guaranteed, but the transmission of the low-priority channel cannot be guaranteed, which reduces the transmission efficiency and reliability of the system.

Considering that in NR R17, in order to reduce the impact of discarding low-priority uplink channels on system efficiency, multiplexing and transmission of information carried in overlapping channels corresponding to different priorities is supported. In the multiplexing transmission process, the transmission performance requirements (reliability, delay) of the high-priority information (information carried in the high-priority channel) must be guaranteed first. However, if the transmission process of the high-priority information is significantly modified in the multiplexing transmission, the transmission reliability of the high-priority information will be reduced. Therefore, in the process of supporting the multiplexed transmission of information with different priorities, how to take into account the system efficiency on the basis of ensuring the reliability of the high-priority feedback information is a technical problem that needs to be solved urgently in the art.

Based on this, the embodiments of the present application provide a wireless communication method and device, which can take into account system efficiency while ensuring the reliability of high-priority feedback information in the process of supporting multiplexed transmission of information with different priorities.

FIG. 4 is a schematic flowchart of a wireless communication method 200 provided by an embodiment of the present application. The method 200 may be performed by a terminal device, for example, the method 200 may be performed by a terminal device as shown in FIG. 1 .

S210: In the case where the feedback resources used to carry the first feedback codebook overlap with the feedback resources used to carry the second feedback codebook, use the third feedback codebook to transmit all the information in at least one piece of first feedback information and at least one piece of the first feedback information. Part or all of the information in a second feedback information; the priority of the first feedback codebook is different from the priority of the second feedback codebook, and the first feedback codebook includes the at least one first feedback codebook 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 is the same as the number of bits included in the third feedback codebook.

In this embodiment, it is assumed that the terminal configuration supports the first feedback codebook and the 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 as an example, the first codebook is used to feed back high-priority ACK/NACK information (that is, the codebook only includes high-priority ACK/NACK information , or, the codebook includes high-priority ACK/NACK information and occupancy information (NACK), and the priority of the uplink control channel carrying the first feedback codebook is high, that is, the priority information is 1 (priority index=1 ); taking the second feedback codebook as an example of a low-priority codebook, the second codebook is used to feed back low-priority ACK/NACK information (that is, the codebook only includes low-priority ACK/NACK information, Or, the codebook includes low-priority ACK/NACK information and occupancy information (NACK), and the priority of the uplink control channel carrying the second feedback codebook is low, that is, the priority information is 0 (priority index=0) .

It should be noted that, the feedback resources involved in the embodiments of the present application may be any time-domain resources used for sending feedback information. For example, a physical uplink control channel (Physical Uplink Control Channel, PUCCH) resource or a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) resource.

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

In some embodiments, some or all of the information in the at least one second feedback information is located in a bit position not occupied by the at least one first feedback information in the third feedback codebook. In other words, the bit positions occupied by part or all of the at least one second feedback information in the third feedback codebook include the unoccupied bit positions of the at least one first feedback information in the third feedback codebook bit position. In an implementation manner, some unoccupied bit positions of the at least one first feedback information in the third feedback codebook are used to carry part or all of the information in the at least one second feedback information, and in another In an implementation manner, all bit positions not occupied by the at least one first feedback information in the third feedback codebook are used to carry part or all of the information in the at least one second feedback information.

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 an implementation manner, 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 used to carry the uplink channel of the first feedback codebook may be semi-statically configured resources or dynamically configured resources. If the first feedback codebook is a Type-1 feedback codebook, the resources used to carry the uplink channel of the first feedback codebook are semi-static resources, and if the first feedback codebook is a Type-2 feedback codebook In this case, the resources used to carry the uplink channel of the first feedback codebook are dynamically configured resources.

In some embodiments, the priority of the first feedback codebook is higher than the priority of the second feedback codebook.

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

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

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

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 at least one second PDSCH received in the second PDSCH candidate reception opportunity set corresponding feedback information.

In some embodiments, the at least one second feedback information is feedback information of at least one second PDSCH respectively; the third feedback codebook includes the at least one PDSCH candidate receiver opportunity set received in the first PDSCH candidate receiver opportunity set. second feedback information corresponding to one second PDSCH in one second PDSCH; or, the third feedback codebook includes second feedback information corresponding to one second PDSCH in the at least one second PDSCH, the one The end symbol of the second PDSCH is located in the first PDSCH candidate receiver opportunity set; or, the third feedback codebook includes second feedback information corresponding to one second PDSCH in the at least one second PDSCH, the The end symbol of a second PDSCH is located in one PDSCH candidate resource opportunity in the first PDSCH candidate reception opportunity set.

It should be noted that the third feedback codebook includes the second feedback information corresponding to one second PDSCH in the at least one second PDSCH received in the first PDSCH candidate receiving opportunity set, which can be understood as : the third feedback codebook at least includes second feedback information corresponding to one second PDSCH in the at least one second PDSCH received in the first PDSCH candidate receiver opportunity set, or the third The feedback codebook may include second feedback information corresponding to a plurality of second PDSCHs in the at least one second PDSCH received in the first PDSCH candidate receiver opportunity set. This embodiment of the present application does not limit this.

In some embodiments, the method 200 may further include:

According to the first PDSCH candidate reception opportunities occupied by the one second PDSCH in the first PDSCH candidate reception opportunity set, determine the position of the second feedback information corresponding to the one second PDSCH in the third feedback codebook Occupied bit positions.

In other words, the bit position occupied by the second feedback information corresponding to the one second PDSCH in the third feedback codebook is based on the first PDSCH occupied by the one second PDSCH in the first PDSCH candidate receiver opportunity set Candidate receivers are determined.

In an implementation manner, it is assumed that the first feedback codebook is configured as a Type-1 codebook, and the second feedback codebook is configured as Type-1 or Type-2 (which may not be limited by the codebook type). If an uplink channel that transmits the first feedback codebook (uplink control channel PUCCH or uplink shared channel PUSCH) overlaps with the uplink channel that transmits the second feedback codebook (overlap in time domain), it may be completely overlapping or partially overlapping, so The terminal transmits a special first feedback codebook (that is, the third feedback codebook), wherein the third feedback codebook includes a PDSCH candidate receiver opportunity set (the set of M_(A, c) occurrences for candidate PDSCH The feedback information corresponding to all PDSCHs received on receptions) (the PDSCH ends in the one PDSCH candidate receiver opportunity set), that is, including high-priority ACK/NACK information and low-priority ACK/NACK information. In other words, the third feedback codebook corresponds to a PDSCH candidate receiver opportunity set. The terminal abandons transmission of the low-priority ACK/NACK information received in the one PDSCH candidate receiver opportunity set in the second feedback codebook.

FIG. 5 is a schematic block diagram of at least one first feedback information and at least one second feedback information provided by an embodiment of the present application.

As shown in FIG. 5 , the first feedback codebook is transmitted through HP PUCCH (high priority PUCCH), and the first PDSCH candidate reception opportunity set corresponding to the first feedback codebook includes 4 PDSCH candidate reception opportunities, namely PDSCH candidates Receiving opportunities 1 to 4, each PDSCH candidate receiving opportunity is a sub-slot, and the first feedback codebook includes 4 bits (it is assumed that the maximum number of PDSCH codewords is 1). The terminal receives PDSCH in PDSCH

candidate reception opportunities

1 and 3 in the first PDSCH candidate reception opportunity set, and its corresponding ACK/NACK is high priority, then the first feedback codebook is {b1, NACK, b2, NACK }. In addition, the second feedback codebook is transmitted through LP PUCCH (low priority PUCCH), and the second PDSCH candidate reception opportunity set corresponding to the second feedback codebook includes 3 PDSCH candidate reception opportunities, namely PDSCH candidate reception opportunities 1~ 3. Each PDSCH candidate receiving opportunity is a time slot, that is, the second PDSCH candidate receiving opportunity set includes time slots 1 to 3, and the terminal receives PDSCH 3 and PDSCH 4, the corresponding ACK/NACK information is low priority. In an implementation manner, if the second feedback codebook is configured as a Type-2 codebook, the second feedback codebook is {b3, b4}. In another implementation manner, if the second codebook is configured as a Type-1 codebook, the second feedback codebook includes 3 bits (assuming that 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 i is a positive integer.

It should be noted that, each PDSCH candidate receiving opportunity mentioned above in the embodiment of the present application may also be a sub-slot or a time slot or the like.

In this embodiment, a third feedback codebook with the same size as the first feedback codebook may 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, referring to FIG. 5, the HP PUCCH and the LP PUCCH overlap, and the terminal sends a special first feedback codebook (ie, the third feedback codebook) through the HP PUCCH, and the third feedback codebook may include {b1, b4 , b2, NACK}. That is, for PDSCH 4 corresponding to low-priority ACK/NACK information, whose end position belongs to the first PDSCH candidate receiving opportunity set (ie PDSCH candidate receiving opportunities 1 to 4), its ACK/NACK information is combined with high-priority ACK/NACK information. The NACK information is multiplexed to obtain a third feedback codebook with the same size as the first feedback codebook for transmission. In addition, there is no ACK/NACK feedback for LP PDSCH 3 that do not fall within the first PDSCH candidate reception opportunity set (ie, PDSCH candidate reception opportunities PDSCH candidate reception opportunities 1 to 4).

In this embodiment, a third feedback codebook with the same size as the first feedback codebook is used to transmit all the feedback information in the first feedback codebook and part of the feedback information in the second feedback codebook, It can prevent LP ACK/NACK from being discarded to a certain extent and improve system efficiency. In addition, significant modification to the HP PUCCH transmission process is avoided, and the reliability of the HP PUCCH transmission can be guaranteed.

It should be noted that, in the case where the first PDSCH candidate reception opportunity set and the second PDSCH candidate reception opportunity set overlap, within one PDSCH candidate reception opportunity in the first PDSCH candidate reception opportunity set, the terminal It is possible for the device to receive a first PDSCH and a second PDSCH at the same time.

In some embodiments, when a first PDSCH and a second PDSCH are received in one PDSCH candidate receiving opportunity in the first PDSCH candidate receiving opportunity set, the third feedback codebook includes the First feedback information corresponding to a first PDSCH.

For example, the third feedback codebook includes first feedback information corresponding to the one first PDSCH and second feedback information corresponding to the one second PDSCH. For another example, the third feedback codebook includes first feedback information corresponding to the one first PDSCH and does not include second feedback information corresponding to the one second PDSCH.

For example, in the Type-1 codebook, one PDSCH candidate receiver may correspond to 1 or 2 ACK/NACK bits (depending on the maximum number of codewords in a PDSCH). If there are both LP PDSCH and HP PDSCH ending symbols in one PDSCH candidate receiving opportunity, the HP ACK/NACK information is mapped to the Type-1 feedback codebook, and the LP ACK/NACK is not transmitted.

FIG. 6 is another schematic block diagram of at least one first feedback information and at least one second feedback information provided by an embodiment of the present application.

As shown in Figure 6, for HP PDSCH candidate reception opportunity 2, the end symbols of PDSCH 1 and PDSCH 4 are within one PDSCH candidate reception opportunity. At this time, only the feedback information of PDSCH 4 is mapped into the codebook, then the Type-1 codebook is {b3, b4, b2}, where bi is the ACK/NACK information corresponding to PDSCHi. In this embodiment, a third feedback codebook with the same size as the first feedback codebook is used to transmit all the feedback information in the first feedback codebook and part or all of the feedback in the second feedback codebook information, which can prevent LP ACK/NACK from being discarded to a certain extent and improve system efficiency. In addition, significant modification to the HP PUCCH transmission process is avoided, and the reliability of the HP PUCCH transmission can be guaranteed.

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 some embodiments, the first feedback codebook is a Type-1 feedback codebook.

It should be noted that the third feedback codebook includes the second feedback information corresponding to one second PDSCH in the at least one second PDSCH received in the first PDSCH candidate receiving opportunity set, which can be understood as : The third feedback codebook at least includes second feedback information corresponding to one second PDSCH in the at least one second PDSCH received in the first PDSCH candidate receiver opportunity set, that is, the third feedback The codebook may include second feedback information corresponding to a plurality of second PDSCHs in the at least one second PDSCH received in the first PDSCH candidate receiver opportunity set.

In some embodiments, the method 300 may further include:

It should be understood that the steps in the method 300 may refer to the corresponding steps in the method 200, which are not repeated here for brevity.

In the above, whether to transmit the third feedback codebook is determined by the terminal or the network device judging whether the feedback resources used to carry the first feedback codebook and the feedback resources used to carry the second feedback codebook overlap, but this The application embodiment is not limited to this. The present application also provides a wireless communication method, in which a network device instructs a terminal device whether to transmit a third feedback codebook, so as to implement a scheme of multiplexing transmission using the third feedback codebook.

The method 400 may be executed interactively by a terminal device and a network device. The terminal device shown in FIG. 8 may be the terminal device shown in FIG. 1 , and the network device shown in FIG. 8 may be the access network device shown in FIG. 1 .

As shown in FIG. 8, the method 400 may include:

S410: Receive first information, where the first information is used to configure the terminal device to transmit feedback information by using the first feedback codebook and the second feedback codebook, where the priority of the first feedback codebook is the same as that of the second feedback code The priorities of the books are different, the first feedback codebook includes at least one piece of 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 The radio resource control (Radio Resource Control, RRC) signaling may also be a media access control (Media Access Control, MAC) control element (Control Element, CE), which is not specifically limited in this embodiment of the present application.

S420: Receive first indication information, where the first indication information is used to indicate that the first feedback codebook or the third feedback codebook is used to transmit feedback information in a time unit, where the third feedback codebook includes the For all the information in at least one piece of first feedback information and some or all of the information in at least one piece of 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 that the terminal device feeds back feedback information of one priority or feedback information of two priorities, or the first The indication information is used to indicate whether the terminal device uses the third feedback codebook to transmit feedback information. It should be noted that the first indication information may be RRC signaling or MAC CE, which is not specifically limited in this embodiment of the present application. The time unit may be a set of PDSCH candidate reception opportunities, or may be a time period whose time length is a certain threshold, and the certain threshold may be predefined or configured by the network. For example, the time unit may comprise at least one slot or at least one symbol.

In this embodiment, it is assumed that the terminal configuration supports the first feedback codebook and the 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 codebook as an example, the first codebook is used to feed back high-priority ACK/NACK information (that is, the codebook only includes high-priority ACK/NACK information or , high priority ACK/NACK information and occupancy information NACK), the priority of the uplink control channel carrying the first feedback codebook is high, that is, the priority information is 1 (priority index=1); For example, the second codebook is a low-priority codebook. The second codebook is used to feed back low-priority ACK/NACK information (that is, the codebook only includes low-priority ACK/NACK information or, low-priority ACK/NACK information). NACK information and occupancy information NACK), the priority of the uplink control channel carrying the second feedback codebook is low, that is, the priority information is 0 (priority index=0).

Based on the above technical solutions, in the case where the feedback resources used to carry the first feedback codebook overlap with the feedback resources used to carry the second feedback codebook, the third feedback codebook is used to transmit all of the at least one first feedback information The information and some or all of the information in the at least one second feedback information can prevent the second feedback information from being discarded to a certain extent, and improve the system efficiency. In addition, 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 a manner of generating the first feedback codebook, avoiding The transmission process of the at least one piece of first feedback information produces significant modifications, which can ensure the reliability of the at least one piece of first feedback information.

In some embodiments, some or all of the information in the at least one second feedback information is located in a bit position not occupied by the at least one first feedback information in the third feedback codebook. In an implementation manner, a partial bit position not occupied by the at least one first feedback information in the third feedback codebook is used to carry the second feedback information. In another implementation manner, the first feedback information is used for carrying the second feedback information. All the bit positions not occupied by the at least one first feedback information in the three-feedback codebook are used to carry the second feedback information.

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 an implementation manner, 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 used to carry the uplink channel of the first feedback codebook may be semi-static resources or dynamically configured resources. If the first feedback codebook is a Type-1 feedback codebook, the resources used to carry the uplink channel of the first feedback codebook are semi-static resources, and if the first feedback codebook is a Type-2 feedback codebook In this case, the resources used to carry the uplink channel of the first feedback codebook are dynamically configured resources.

In other words, the second indication information is used to instruct the terminal device to send a Type-1 feedback codebook.

In an implementation manner, the terminal device receives the DCI sent by the network device, where the DCI includes the second indication information. For example, when the terminal device receives the DCI, the DCI indicates one HP PUCCH resource, and the DCI is also used to indicate the transmission of a Type-1 codebook. Optionally, the DCI may further include the first indication information, and based on this, the terminal device may determine the one Type-1 codebook, that is, the third feedback codebook, based on the DCI.

In an implementation manner, it is assumed that the first feedback codebook is configured as a Type-1 codebook, and the second feedback codebook is configured as Type-1 or Type-2 (which may not be limited by the codebook type). If an uplink channel that transmits the first feedback codebook (uplink control channel PUCCH or uplink shared channel PUSCH) overlaps with the uplink channel that transmits the second feedback codebook (overlap in time domain), it may be completely overlapping or partially overlapping, so The terminal transmits a special first feedback codebook (that is, the third feedback codebook), wherein the third feedback codebook includes a PDSCH candidate receiver opportunity set (the set of M_(A, c) occurrences for candidate PDSCH The feedback information corresponding to all PDSCHs received on receptions) (the PDSCH ends in the one PDSCH candidate receiver opportunity set), that is, including high-priority ACK/NACK information and low-priority ACK/NACK information. In other words, the third feedback codebook corresponds to a PDSCH candidate receiver opportunity set. The terminal aborts the transmission of the low-priority ACK/NACK information received in the one PDSCH candidate receiver opportunity set in the second feedback codebook.

In addition, the second feedback codebook is transmitted through LP PUCCH (low priority PUCCH), and the second PDSCH candidate reception opportunity set corresponding to the second feedback codebook includes 3 PDSCH candidate reception opportunities, namely PDSCH candidate reception opportunities 1~ 3. Each PDSCH candidate receiving opportunity is a time slot, that is, the second PDSCH candidate receiving opportunity set includes time slots 1 to 3, and the terminal receives PDSCH 3 and PDSCH 4, the corresponding ACK/NACK information is low priority. In an implementation manner, if the second feedback codebook is configured as a Type-2 codebook, the second feedback codebook is {b3, b4}. In another implementation manner, if the second codebook is configured as a Type-1 codebook, the second feedback codebook includes 3 bits (assuming that 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.

In an implementation manner, the first feedback codebook is a high-priority feedback codebook, that is, the priority of the first feedback codebook is higher than the priority of the second feedback codebook. Based on this, with reference to FIG. 9 , if the first indication information is used to indicate that the first feedback codebook is used to transmit the feedback information in the time unit, the first feedback codebook may include: at the PDSCH candidate reception opportunity High-priority ACK/NACK information corresponding to PDSCH is received in 1 to 4: that is, the first feedback codebook is {b1, NACK, b2, NACK}; if the first indication information is used to indicate that in the time unit Using the third feedback codebook to transmit feedback information, the third feedback codebook may include: high-priority and low-priority ACK/NACK information corresponding to PDSCH received in PDSCH candidate receiving opportunities 1 to 4, that is, all The third feedback codebook is {b1, b4, b2, NACK}.

In this embodiment, the network device can flexibly control the terminal to multiplex and transmit ACK/NACK information of different priorities, so as to avoid the ACK/NACK information of low priority from being discarded, and improve the system efficiency.

In another implementation manner, the first feedback codebook is a low-priority feedback codebook, that is, the priority of the first feedback codebook is lower than the priority of the second feedback codebook. Based on this, with reference to FIG. 9 , if the first indication information is used to indicate that the first feedback codebook is used to transmit the feedback information in the time unit, the first feedback codebook may include: in the corresponding PDSCH candidate The low-priority ACK/NACK information corresponding to the PDSCH is received in the receiving opportunity: for example, if the first feedback codebook is configured as a Type-2 codebook, the first feedback codebook is {b3, b4}; A codebook is configured as a Type-1 codebook, and the first feedback codebook includes 3 bits (assuming that 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 the third feedback codebook is used to transmit the feedback information in the time unit, the third feedback codebook may include: receiving a high signal corresponding to the PDSCH in the corresponding PDSCH candidate receiving opportunity The priority and low priority ACK/NACK information, that is, the third feedback codebook is {b3, b4, b2}.

In this embodiment, the network device can flexibly control the terminal to multiplex and transmit ACK/NACK information of different priorities, and retransmit the high-priority ACK/NACK information through the LP PUCCH (the high-priority ACK/NCAK information itself has corresponding PUCCH), thereby improving the reliability of high-priority ACK/NACK information.
