[0039] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, 5G communication system or future communication system, etc.

[0041] For example, the communication system 100 used in the embodiment of the present application is as follows: Figure 1As shown. The communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120. The network device 110 may provide communication coverage for a specific geographical area and may communicate with terminals located within the coverage area. Optionally, the network device 110 may be an evolved base station (eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (CRAN), or the network device may be a mobile switching center, a relay station, an access point, an in-vehicle device, a wearable device, a hub, a switch, a bridge, a router, a network-side device in a 5G network, or a network device in a future communication system, etc.

[0042] The communication system 100 also includes at least one terminal device 120 located within the coverage area of the network device 110. The terminal device 120 is connected to the network device 110 via a wired line or a wireless interface. The terminal 110 connected to the network device 110 via a wireless interface can be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal". The terminal can refer to an access terminal, user equipment (UE), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless terminal device, a user agent or a user device, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal in a 5G network or a terminal in a future evolved PLMN, etc.

[0043] Optionally, terminal devices 120 may perform device-to-device (D2D) communication with each other.

[0044] Optionally, the 5G communication system or 5G network may also be referred to as a New Radio (NR) system or NR network.

[0045] Figure 1 One network device and two terminals are shown as an example. Optionally, the communication system 100 may include multiple network devices and each network device may include another number of terminals within its coverage area. This embodiment of the present application does not limit this.

[0046] Optionally, the communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present application.

[0047] It should be understood that the device with communication function in the network / system in the embodiment of the present application can be called a communication device. Figure 1 Taking the communication system 100 shown as an example, the communication system 100 may include a network device 110 and a terminal device 120 with communication functions. The network device 110 and the terminal device 120 may be the specific devices described above and will not be repeated here; the communication system 100 may also include other devices, such as a network controller, a mobile management entity and other network entities, which is not limited in the embodiments of the present application.

[0048] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0049] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

[0050] The Ultra-Reliable Low-Latency Communications (URLLC) project introduced a solution that cancels the transmission of low-priority uplink channels and only transmits high-priority uplink channels when the time domain resources of uplink channels of different priorities overlap, thereby ensuring low latency and high reliability of URLLC services. However, in some scenarios, the content in the canceled low-priority uplink channels still has the opportunity to be transmitted on non-conflicting resources. At the 3GPP meeting, it was proposed to no longer transmit the content in the canceled low-priority uplink channels for the above scenarios.

[0051] Related technologies show that HARQ-ACK information pointing to the same time slot or sub-time slot and corresponding to the same priority constitutes a HARQ-ACK codebook, and the terminal device uses the PUCCH indicated by the most recently received downlink control information (Downlink Control Information, DCI) to transmit the HARQ-ACK codebook. Figure 2As shown, LP represents low priority and HP represents high priority. The HARQ-ACK1 information corresponding to LP PDSCH1 is transmitted through LP PUCCH1, and the HARQ-ACK2 information corresponding to LP PDSCH2 is transmitted through LP PUCCH2. The HARQ-ACK1 information and HARQ-ACK2 information point to the same time slot (i.e., time slot n) and correspond to the same physical priority (i.e., LP). Therefore, the HARQ-ACK1 information and HARQ-ACK2 information will form a HARQ-ACK codebook, which is transmitted through LP PUCCH2. However, according to the conclusion of the above meeting, when the time domain resources of LP PUCCH1 and HP PUCCH or HP PUSCH overlap, the transmission of LP PUCCH1 is canceled and the HARQ-ACK1 information in LP PUCCH1 will be lost. Among them, HP PUCCH is used to transmit the HARQ-ACK information of HP PDSCH, HP PUSCH is scheduled based on the uplink grant (UL grant), and HP PUSCH is used to transmit uplink data. Therefore, it is necessary to clarify how to construct the HARQ-ACK codebook transmitted in LP PUCCH2. To this end, the following technical solutions of the embodiments of the present application are proposed.

[0052] Figure 3 This is a flow diagram of the control information transmission method provided in the embodiment of the present application. Figure 1 ,like Figure 3 As shown, the control information transmission method includes the following steps:

[0053] Step 301: The terminal device receives a first downlink signal, and HARQ-ACK information corresponding to the first downlink signal is transmitted through a first PUCCH.

[0054] In an embodiment of the present application, the first downlink signal is transmitted via a first PDSCH. That is, the terminal device receives a first PDSCH that carries the first downlink signal. The HARQ-ACK information corresponding to the first downlink signal is transmitted via a first PUCCH. Here, optionally, the configuration information of the first PUCCH is carried in the DCI used to schedule the first PDSCH.

[0055] Step 302: The terminal device receives a second downlink signal, and the HARQ-ACK information corresponding to the second downlink signal is transmitted through a second PUCCH, wherein the second PUCCH and the first PUCCH correspond to the same HARQ-ACK codebook.

[0056] In an embodiment of the present application, the second downlink signal is transmitted via a second PDSCH. That is, the terminal device receives a second PDSCH that carries the second downlink signal. The HARQ-ACK information corresponding to the second downlink signal is transmitted via a second PUCCH. Here, optionally, the configuration information of the second PUCCH is carried in the DCI used to schedule the second PDSCH.

[0057] In this embodiment of the present application, the second PUCCH and the first PUCCH correspond to the same HARQ-ACK codebook, that is, the HARQ-ACK information corresponding to the first downlink signal and the HARQ-ACK information corresponding to the second downlink signal can form a HARQ-ACK codebook. It should be noted that the condition that the HARQ-ACK information corresponding to the first downlink signal and the HARQ-ACK information corresponding to the second downlink signal can form a HARQ-ACK codebook is that the HARQ-ACK information corresponding to the first downlink signal and the HARQ-ACK information corresponding to the second downlink signal point to the same time slot or sub-time slot and correspond to the same priority.

[0058] It should be noted that the priority of the HARQ-ACK information is also the priority of the PUCCH used to transmit the HARQ-ACK information. It can be seen that the second PUCCH and the first PUCCH have the same priority.

[0059] Step 303: The terminal device cancels transmission of the first PUCCH and transmits the second PUCCH, where the second PUCCH carries a first HARQ-ACK codebook, and the first HARQ-ACK codebook at least includes HARQ-ACK information corresponding to the second downlink signal.

[0060] In an embodiment of the present application, before receiving the second downlink signal, the terminal device also receives a third downlink signal, that is, the time domain resources of the third downlink signal are located before the time domain resources of the second downlink signal. If the first uplink transmission channel corresponding to the third downlink signal overlaps with the time domain resources of the first PUCCH, the terminal device determines to cancel transmission of the first PUCCH; if the first uplink transmission channel corresponding to the third downlink signal does not overlap with the time domain resources of the second PUCCH, the terminal device determines to transmit the second PUCCH.

[0061] In the embodiment of the present application, the third downlink signal and the first uplink transmission channel corresponding to the third downlink signal may be implemented in the following two ways:

[0062] A) In an optional embodiment of the present application, the third downlink signal is transmitted via a third PDSCH, that is, the terminal device receives a third PDSCH, which carries the third downlink signal. The HARQ-ACK information corresponding to the third downlink signal is transmitted via a third PUCCH (i.e., the first uplink transmission channel). Here, optionally, the configuration information of the third PUCCH is carried in the DCI used to schedule the third PDSCH.

[0063] B) In an optional embodiment of the present application, the third downlink signal is transmitted via a fourth PUCCH, that is, the terminal device receives a fourth PUCCH, which carries the third downlink signal. Here, the DCI in the fourth PUCCH is used to schedule PUSCH (i.e., the first uplink transmission channel) transmission, for example, the third downlink signal carries UL grant information of the PUSCH.

[0064] In an embodiment of the present application, the priority of the first uplink transmission channel (such as the third PUCCH or PUSCH) corresponding to the third downlink signal is higher than the priority of the first PUCCH and the second PUCCH. Wherein, 1) when the time domain resources of the first uplink transmission channel corresponding to the third downlink signal overlap with those of the first PUCCH, the terminal device determines to cancel the transmission of the first PUCCH; 2) when the time domain resources of the first uplink transmission channel corresponding to the third downlink signal do not overlap with those of the second PUCCH, the terminal device determines to transmit the second PUCCH.

[0065] In this embodiment of the present application, the second PUCCH carries a first HARQ-ACK codebook, and the first HARQ-ACK codebook includes at least HARQ-ACK information corresponding to the second downlink signal. The specific implementation of the first HARQ-ACK codebook is described below.

[0066] Method 1

[0067] The first HARQ-ACK codebook includes HARQ-ACK information corresponding to the second downlink signal. The first HARQ-ACK codebook does not include HARQ-ACK information or placeholder information corresponding to the first downlink signal. Further, the first HARQ-ACK codebook does not include HARQ-ACK information or placeholder information corresponding to at least one downlink signal before the first downlink signal, and the at least one downlink signal corresponds to the same HARQ-ACK codebook.

[0068] In the embodiment of the present application, the first HARQ-ACK codebook only includes HARQ-ACK information corresponding to the downlink signal after the first downlink signal corresponding to the PUCCH (ie, the first PUCCH) is canceled.

[0069] It should be noted that the first HARQ-ACK codebook includes N bits, where N is a positive integer, and each bit of the N bits corresponds to a downlink signal (ie, corresponds to a PDSCH), and the value of the bit is used to represent the HARQ-ACK information of the downlink signal corresponding to the comparison bit. For example, if the value of the bit is 1, it indicates that the HARQ-ACK information of the downlink signal corresponding to the bit is ACK, and if the value of the bit is 0, it indicates that the HARQ-ACK information of the downlink signal corresponding to the bit is NACK.

[0070] I) In an optional manner, when the first HARQ-ACK codebook is a first type HARQ-ACK codebook, the correspondence between the bits in the first HARQ-ACK codebook and the downlink signal is determined based on semi-static configuration information. Here, the semi-static configuration information is used to determine the feedback timing set and the PDSCH time domain resource indication set, etc.

[0071] It can be understood that the bits contained in the first HARQ-ACK codebook correspond to the physical resources of the PDSCH that can be transmitted in the feedback window configured by the semi-static configuration information, and the number of PDSCHs actually scheduled is less than or equal to the number of PDSCHs that can be transmitted in the feedback window.

[0072] It should be noted that, in the first HARQ-ACK codebook, HARQ-ACK information corresponding to the downlink signal after the first downlink signal corresponding to the first PUCCH is valid.

[0073] II) In an optional manner, when the first HARQ-ACK codebook is a second type HARQ-ACK codebook, the correspondence between the bits in the first HARQ-ACK codebook and the downlink signal is determined based on a first target downlink assignment index (Downlink Assignment Index, DAI) of the downlink signal; wherein the first target DAI is the DAI of the downlink signal, wherein the counting of the DAI of the downlink signal starts from the first downlink signal after the first downlink signal in the multiple downlink signals corresponding to the first HARQ-ACK codebook; or, the first target DAI is the DAI of the downlink signal minus the DAI of the first downlink signal, wherein the counting of the DAI of the downlink signal starts from the first downlink signal in the multiple downlink signals corresponding to the first HARQ-ACK codebook.

[0074] The above technical solution is illustrated below with reference to specific examples.

[0075] Example 1

[0076] 1. The terminal device receives a first downlink signal, and the HARQ-ACK information corresponding to the first downlink signal is transmitted through the first PUCCH.

[0077] 2. The terminal device receives a third downlink signal. The first uplink transmission channel corresponding to the third downlink signal overlaps with the time domain resources of the first PUCCH. The terminal device cancels transmission of the first PUCCH.

[0078] Optionally, the starting position of the time domain resources of the first downlink signal is before the starting position of the time domain resources of the third downlink signal.

[0079] 3. The terminal device receives the second downlink signal, and the HARQ-ACK information corresponding to the second downlink signal is transmitted through the second PUCCH.

[0080] The time domain resources of the second downlink signal are subsequent to the time domain resources of the third downlink signal, and the time domain resources of the second PUCCH and the first uplink transmission channel do not overlap.

[0081] The second PUCCH and the first PUCCH are in the same time unit (eg, time slot, sub-time slot) and have the same priority, so the second PUCCH and the first PUCCH correspond to the same HARQ-ACK codebook.

[0082] 4. The terminal device sends a first HARQ-ACK codebook through the second PUCCH, wherein the first HARQ-ACK codebook includes HARQ-ACK information corresponding to the second downlink signal, and does not include HARQ-ACK information or placeholder information corresponding to the first downlink signal.

[0083] Further, the first HARQ-ACK codebook does not include HARQ-ACK information or placeholder information corresponding to all downlink signals belonging to the same HARQ-ACK codebook (that is, the first HARQ-ACK codebook) before the first downlink signal.

[0084] That is, the first HARQ-ACK codebook only includes HARQ-ACK information corresponding to the downlink signal after the downlink signal corresponding to the canceled PUCCH (ie, the first PUCCH).

[0085] 1) If the first HARQ-ACK codebook belongs to the first type of HARQ-ACK codebook, the correspondence between each bit in the first HARQ-ACK codebook and the downlink signal is determined according to the semi-static configuration information (semi-static configuration information is used to determine the feedback timing set and the PDSCH time domain resource indication set, etc.), but only the HARQ-ACK information corresponding to the downlink signal after the downlink signal corresponding to the canceled PUCCH (ie, the first PUCCH) is valid.

[0086] 2) If the first HARQ-ACK codebook belongs to the second type of HARQ-ACK codebook, the correspondence between each bit in the first HARQ-ACK codebook and the downlink signal is determined according to the DAI. Specifically,

[0087] Method 1: The DAI of the downlink signal (such as the second downlink signal) after the downlink signal corresponding to the canceled PUCCH (i.e., the first PUCCH) is counted from the beginning (e.g., starting from 0). The correspondence between each bit in the first HARQ-ACK codebook and the downlink signal is directly determined according to the DAI of the downlink signal.

[0088] Method 2: Regardless of whether the downlink signal before or after the downlink signal corresponding to the canceled PUCCH (i.e., the first PUCCH) is arranged in the same HARQ-ACK codebook (i.e., the first HARQ-ACK codebook) with the DAI of the downlink signal. The correspondence between the bits in the first HARQ-ACK codebook and the downlink signal is determined according to the DAI of the downlink signal and the DAI of the downlink signal corresponding to the canceled PUCCH, for example, the DAI of the downlink signal minus the DAI of the downlink signal corresponding to the canceled PUCCH.

[0089] Take the second type of HARQ-ACK codebook construction as an example, Figure 4 As shown, the three downlink signals corresponding to the first HARQ-ACK codebook correspond to three PDSCHs, namely PDSCH0, PDSCH1, and PDSCH2. Among them, the time domain resources of the PUCCH corresponding to PDSCH1 overlap with the PUCCH corresponding to PDSCH3, and the priority of the PUCCH corresponding to PDSCH1 is lower than the priority of the PUCCH corresponding to PDSCH3. Then, the PUCCH corresponding to PDSCH1 is deleted. The PUCCH corresponding to PDSCH2 is transmitted, and the first HARQ-ACK codebook carried in the PUCCH contains the HARQ-ACK information corresponding to PDSCH2, wherein PDSCH2 corresponds to DAI=2.

[0090] Through the above technical solution, the additional transmission of the HARQ-ACK information of the downlink signal corresponding to the first PUCCH (that is, the PUCCH in which the time domain resources conflict) is avoided, thereby reducing the implementation complexity of the terminal device.

[0091] Method 2

[0092] The first HARQ-ACK codebook includes HARQ-ACK information corresponding to the second downlink signal. The first HARQ-ACK codebook also includes HARQ-ACK information corresponding to the first downlink signal. Further, optionally, the first HARQ-ACK codebook also includes HARQ-ACK information corresponding to at least one downlink signal before the first downlink signal, and the at least one downlink signal corresponds to the same HARQ-ACK codebook.

[0093] It should be noted that the first HARQ-ACK codebook includes N bits, where N is a positive integer, and each bit of the N bits corresponds to a downlink signal (ie, corresponds to a PDSCH), and the value of the bit is used to represent the HARQ-ACK information of the downlink signal corresponding to the comparison bit. For example, if the value of the bit is 1, it indicates that the HARQ-ACK information of the downlink signal corresponding to the bit is ACK, and if the value of the bit is 0, it indicates that the HARQ-ACK information of the downlink signal corresponding to the bit is NACK.

[0094] I) In an optional manner, when the first HARQ-ACK codebook is a first type HARQ-ACK codebook, the correspondence between the bits in the first HARQ-ACK codebook and the downlink signal is determined based on semi-static configuration information. Here, the semi-static configuration information is used to determine the feedback timing set and the PDSCH time domain resource indication set, etc.

[0095] It can be understood that the bits contained in the first HARQ-ACK codebook correspond to the physical resources of the PDSCH that can be transmitted in the feedback window configured by the semi-static configuration information, and the number of PDSCHs actually scheduled is less than or equal to the number of PDSCHs that can be transmitted in the feedback window.

[0096] II) In an optional manner, when the first HARQ-ACK codebook is a second type HARQ-ACK codebook, the correspondence between the bits in the first HARQ-ACK codebook and the downlink signal is determined based on the first target DAI of the downlink signal; wherein the first target DAI is the DAI of the downlink signal, wherein the counting of the DAI of the downlink signal starts from the first downlink signal of the multiple downlink signals corresponding to the first HARQ-ACK codebook.

[0097] The above technical solution is illustrated below with reference to specific examples.

[0098] Example 2

[0099] 1. The terminal device receives a first downlink signal, and the HARQ-ACK information corresponding to the first downlink signal is transmitted through the first PUCCH.

[0100] 2. The terminal device receives a third downlink signal. The first uplink transmission channel corresponding to the third downlink signal overlaps with the time domain resources of the first PUCCH. The terminal device cancels transmission of the first PUCCH.

[0101] Optionally, the starting position of the time domain resources of the first downlink signal is before the starting position of the time domain resources of the third downlink signal.

[0102] 3. The terminal device receives the second downlink signal, and the HARQ-ACK information corresponding to the second downlink signal is transmitted through the second PUCCH.

[0103] The time domain resources of the second downlink signal are subsequent to the time domain resources of the third downlink signal, and the time domain resources of the second PUCCH and the first uplink transmission channel do not overlap.

[0104] The second PUCCH and the first PUCCH are in the same time unit (eg, time slot, sub-time slot) and have the same priority, so the second PUCCH and the first PUCCH correspond to the same HARQ-ACK codebook.

[0105] 4. The terminal device sends a first HARQ-ACK codebook through the second PUCCH. The first HARQ-ACK codebook includes HARQ-ACK information corresponding to the second downlink signal and HARQ-ACK information corresponding to the first downlink signal. Furthermore, the first HARQ-ACK codebook also includes HARQ-ACK information corresponding to all downlink signals belonging to the same HARQ-ACK codebook (i.e., the first HARQ-ACK codebook) before the first downlink signal.

[0106] 1) If the first HARQ-ACK codebook belongs to the first type of HARQ-ACK codebook, the correspondence between each bit in the first HARQ-ACK codebook and the downlink signal is determined according to the semi-static configuration information (semi-static configuration information is used to determine the feedback timing set and the PDSCH time domain resource indication set, etc.).

[0107] 2) If the first HARQ-ACK codebook belongs to the second type of HARQ-ACK codebook, determine the correspondence between each bit in the first HARQ-ACK codebook and the downlink signal according to the DAI.

[0108] Take the second type of HARQ-ACK codebook construction as an example, Figure 5As shown, the three downlink signals corresponding to the first HARQ-ACK codebook correspond to three PDSCHs, namely PDSCH0, PDSCH1 and PDSCH2. Among them, the time domain resources of the PUCCH corresponding to PDSCH1 overlap with the PUCCH corresponding to PDSCH3, and the priority of the PUCCH corresponding to PDSCH1 is lower than the priority of the PUCCH corresponding to PDSCH3. Then, the PUCCH corresponding to PDSCH1 is deleted. The PUCCH corresponding to PDSCH2 is transmitted, and the first HARQ-ACK codebook carried in the PUCCH contains the HARQ-ACK information corresponding to PDSCH0, the HARQ-ACK information corresponding to PDSCH1, and the HARQ-ACK information corresponding to PDSCH2, among which PDSCH0 corresponds to DAI=0, PDSCH1 corresponds to DAI=1, and PDSCH2 corresponds to DAI=2.

[0109] Through the above technical solution, all HARQ-ACK information needs to be transmitted, avoiding redundant downlink retransmissions and improving system efficiency.

[0110] ●Method 3

[0111] The first HARQ-ACK codebook includes HARQ-ACK information corresponding to the second downlink signal. The first HARQ-ACK codebook also includes placeholder information corresponding to the first downlink signal. Further, the first HARQ-ACK codebook also includes placeholder information corresponding to at least one downlink signal before the first downlink signal, and the at least one downlink signal corresponds to the same HARQ-ACK codebook.

[0112] It should be noted that the first HARQ-ACK codebook includes N bits, where N is a positive integer, and each bit of the N bits corresponds to a downlink signal (ie, corresponds to a PDSCH), and the value of the bit is used to represent the HARQ-ACK information of the downlink signal corresponding to the comparison bit. For example, if the value of the bit is 1, it indicates that the HARQ-ACK information of the downlink signal corresponding to the bit is ACK, and if the value of the bit is 0, it indicates that the HARQ-ACK information of the downlink signal corresponding to the bit is NACK.

[0113] I) In an optional manner, when the first HARQ-ACK codebook is a first type HARQ-ACK codebook, the correspondence between the bits in the first HARQ-ACK codebook and the downlink signal is determined based on semi-static configuration information. Here, the semi-static configuration information is used to determine the feedback timing set and the PDSCH time domain resource indication set, etc.

[0114] It can be understood that the bits contained in the first HARQ-ACK codebook correspond to the physical resources of the PDSCH that can be transmitted in the feedback window configured by the semi-static configuration information, and the number of PDSCHs actually scheduled is less than or equal to the number of PDSCHs that can be transmitted in the feedback window.

[0115] II) In an optional manner, when the first HARQ-ACK codebook is a second type HARQ-ACK codebook, the correspondence between the bits in the first HARQ-ACK codebook and the downlink signal is determined based on the first target DAI of the downlink signal; wherein the first target DAI is the DAI of the downlink signal, wherein the counting of the DAI of the downlink signal starts from the first downlink signal of the multiple downlink signals corresponding to the first HARQ-ACK codebook.

[0116] The above technical solution is illustrated below with reference to specific examples.

[0117] Example 3

[0118] 1. The terminal device receives a first downlink signal, and the HARQ-ACK information corresponding to the first downlink signal is transmitted through the first PUCCH.

[0119] 2. The terminal device receives a third downlink signal. The first uplink transmission channel corresponding to the third downlink signal overlaps with the time domain resources of the first PUCCH. The terminal device cancels transmission of the first PUCCH.

[0120] Optionally, the starting position of the time domain resources of the first downlink signal is before the starting position of the time domain resources of the third downlink signal.

[0121] 3. The terminal device receives the second downlink signal, and the HARQ-ACK information corresponding to the second downlink signal is transmitted through the second PUCCH.

[0122] The time domain resources of the second downlink signal are subsequent to the time domain resources of the third downlink signal, and the time domain resources of the second PUCCH and the first uplink transmission channel do not overlap.

[0123] The second PUCCH and the first PUCCH are in the same time unit (eg, time slot, sub-time slot) and have the same priority, so the second PUCCH and the first PUCCH correspond to the same HARQ-ACK codebook.

[0124] 4. The terminal device sends a first HARQ-ACK codebook through the second PUCCH. The first HARQ-ACK codebook includes the HARQ-ACK corresponding to the second downlink signal and the placeholder information corresponding to the first downlink signal. Furthermore, the first HARQ-ACK codebook also includes the placeholder information corresponding to all downlink signals belonging to the same HARQ-ACK codebook (i.e., the first HARQ-ACK codebook) before the first downlink signal.

[0125] 1) If the first HARQ-ACK codebook belongs to the first type of HARQ-ACK codebook, the correspondence between each bit in the first HARQ-ACK codebook and the downlink signal is determined according to the semi-static configuration information (semi-static configuration information is used to determine the feedback timing set and the PDSCH time domain resource indication set, etc.).

[0126] 2) If the first HARQ-ACK codebook belongs to the second type of HARQ-ACK codebook, determine the correspondence between each bit in the first HARQ-ACK codebook and the downlink signal according to the DAI.

[0127] Take the second type of HARQ-ACK codebook construction as an example, Figure 6 As shown, the three downlink signals corresponding to the first HARQ-ACK codebook correspond to three PDSCHs, namely PDSCH0, PDSCH1 and PDSCH2. Among them, the time domain resources of the PUCCH corresponding to PDSCH1 overlap with the PUCCH corresponding to PDSCH3, and the priority of the PUCCH corresponding to PDSCH1 is lower than the priority of the PUCCH corresponding to PDSCH3. Then, the PUCCH corresponding to PDSCH1 is deleted. The PUCCH corresponding to PDSCH2 is transmitted, and the first HARQ-ACK codebook carried in the PUCCH contains the placeholder information corresponding to PDSCH0, the placeholder information corresponding to PDSCH1 and the HARQ-ACK information corresponding to PDSCH2, among which PDSCH0 corresponds to DAI=0, PDSCH1 corresponds to DAI=1, and PDSCH2 corresponds to DAI=2.

[0128] Through the above technical solution, when the first PUCCH transmission is canceled, the HARQ-ACK information in the first PUCCH is also cleared, avoiding the additional transmission of the HARQ-ACK information of the downlink signal corresponding to the first PUCCH (that is, the PUCCH in which the time domain resources conflict), thereby reducing the implementation complexity of the terminal device.

[0129] ●Method 4

[0130] The first HARQ-ACK codebook includes HARQ-ACK information corresponding to the second downlink signal. The first HARQ-ACK codebook also includes placeholder information corresponding to the first downlink signal. Further, the first HARQ-ACK codebook also includes HARQ-ACK information corresponding to at least one downlink signal before the first downlink signal, and the at least one downlink signal corresponds to the same HARQ-ACK codebook.

[0131] It should be noted that the first HARQ-ACK codebook includes N bits, where N is a positive integer, and each bit of the N bits corresponds to a downlink signal (ie, corresponds to a PDSCH), and the value of the bit is used to represent the HARQ-ACK information of the downlink signal corresponding to the comparison bit. For example, if the value of the bit is 1, it indicates that the HARQ-ACK information of the downlink signal corresponding to the bit is ACK, and if the value of the bit is 0, it indicates that the HARQ-ACK information of the downlink signal corresponding to the bit is NACK.

[0132] I) In an optional manner, when the first HARQ-ACK codebook is a first type HARQ-ACK codebook, the correspondence between the bits in the first HARQ-ACK codebook and the downlink signal is determined based on semi-static configuration information. Here, the semi-static configuration information is used to determine the feedback timing set and the PDSCH time domain resource indication set, etc.

[0133] It can be understood that the bits contained in the first HARQ-ACK codebook correspond to the physical resources of the PDSCH that can be transmitted in the feedback window configured by the semi-static configuration information, and the number of PDSCHs actually scheduled is less than or equal to the number of PDSCHs that can be transmitted in the feedback window.

[0134] II) In an optional manner, when the first HARQ-ACK codebook is a second type HARQ-ACK codebook, the correspondence between the bits in the first HARQ-ACK codebook and the downlink signal is determined based on the first target DAI of the downlink signal; wherein the first target DAI is the DAI of the downlink signal, wherein the counting of the DAI of the downlink signal starts from the first downlink signal of the multiple downlink signals corresponding to the first HARQ-ACK codebook.

[0135] The above technical solution is illustrated below with reference to specific examples.

[0136] Example 4

[0137] 1. The terminal device receives a first downlink signal, and the HARQ-ACK information corresponding to the first downlink signal is transmitted through the first PUCCH.

[0138] 2. The terminal device receives a third downlink signal. The first uplink transmission channel corresponding to the third downlink signal overlaps with the time domain resources of the first PUCCH. The terminal device cancels transmission of the first PUCCH.

[0139] Optionally, the starting position of the time domain resources of the first downlink signal is before the starting position of the time domain resources of the third downlink signal.

[0140] 3. The terminal device receives the second downlink signal, and the HARQ-ACK information corresponding to the second downlink signal is transmitted through the second PUCCH.

[0141] The time domain resources of the second downlink signal are subsequent to the time domain resources of the third downlink signal, and the time domain resources of the second PUCCH and the first uplink transmission channel do not overlap.

[0142] The second PUCCH and the first PUCCH are in the same time unit (eg, time slot, sub-time slot) and have the same priority, so the second PUCCH and the first PUCCH correspond to the same HARQ-ACK codebook.

[0143] 4. The terminal device sends a first HARQ-ACK codebook through the second PUCCH. The first HARQ-ACK codebook includes the HARQ-ACK corresponding to the second downlink signal and the placeholder information corresponding to the first downlink signal. Furthermore, the first HARQ-ACK codebook also includes the placeholder information corresponding to all downlink signals belonging to the same HARQ-ACK codebook (i.e., the first HARQ-ACK codebook) before the first downlink signal.

[0144] 1) If the first HARQ-ACK codebook belongs to the first type of HARQ-ACK codebook, the correspondence between each bit in the first HARQ-ACK codebook and the downlink signal is determined according to the semi-static configuration information (semi-static configuration information is used to determine the feedback timing set and the PDSCH time domain resource indication set, etc.).

[0145] 2) If the first HARQ-ACK codebook belongs to the second type of HARQ-ACK codebook, determine the correspondence between each bit in the first HARQ-ACK codebook and the downlink signal according to the DAI.

[0146] Take the second type of HARQ-ACK codebook construction as an example, Figure 7As shown, the three downlink signals corresponding to the first HARQ-ACK codebook correspond to three PDSCHs, namely PDSCH0, PDSCH1 and PDSCH2. Among them, the time domain resources of the PUCCH corresponding to PDSCH1 overlap with the PUCCH corresponding to PDSCH3, and the priority of the PUCCH corresponding to PDSCH1 is lower than the priority of the PUCCH corresponding to PDSCH3. Then, the PUCCH corresponding to PDSCH1 is deleted. The PUCCH corresponding to PDSCH2 is transmitted, and the first HARQ-ACK codebook carried in the PUCCH contains the HARQ-ACK information corresponding to PDSCH0, the placeholder information corresponding to PDSCH1, and the HARQ-ACK information corresponding to PDSCH2. Among them, PDSCH0 corresponds to DAI=0, PDSCH1 corresponds to DAI=1, and PDSCH2 corresponds to DAI=2.

[0147] Through the above technical solution, the additional transmission of the HARQ-ACK information of the downlink signal corresponding to the first PUCCH (that is, the PUCCH in which the time domain resources conflict) is avoided, thereby reducing the implementation complexity of the terminal device.

[0148] ●Method 5

[0149] The first HARQ-ACK codebook includes HARQ-ACK information corresponding to the second downlink signal. 1) The first HARQ-ACK codebook also includes HARQ-ACK information corresponding to at least one downlink signal preceding the first downlink signal, and the at least one downlink signal corresponds to the same HARQ-ACK codebook. Alternatively, 2) the first HARQ-ACK codebook also includes placeholder information corresponding to at least one downlink signal preceding the first downlink signal, and the at least one downlink signal corresponds to the same HARQ-ACK codebook.

[0150] In this embodiment of the present application, the first HARQ-ACK codebook does not include HARQ-ACK information or placeholder information corresponding to the first downlink signal. The first HARQ-ACK codebook includes HARQ-ACK information or placeholder information corresponding to at least one downlink signal before the first downlink signal.

[0151] It should be noted that the first HARQ-ACK codebook includes N bits, where N is a positive integer, and each bit of the N bits corresponds to a downlink signal (ie, corresponds to a PDSCH), and the value of the bit is used to represent the HARQ-ACK information of the downlink signal corresponding to the comparison bit. For example, if the value of the bit is 1, it indicates that the HARQ-ACK information of the downlink signal corresponding to the bit is ACK, and if the value of the bit is 0, it indicates that the HARQ-ACK information of the downlink signal corresponding to the bit is NACK.

[0152] I) In an optional manner, when the first HARQ-ACK codebook is a first type HARQ-ACK codebook, the correspondence between the bits in the first HARQ-ACK codebook and the downlink signal is determined based on semi-static configuration information. Here, the semi-static configuration information is used to determine the feedback timing set and the PDSCH time domain resource indication set, etc.

[0153] It can be understood that the bits contained in the first HARQ-ACK codebook correspond to the physical resources of the PDSCH that can be transmitted in the feedback window configured by the semi-static configuration information, and the number of PDSCHs actually scheduled is less than or equal to the number of PDSCHs that can be transmitted in the feedback window.

[0154] It should be noted that, in the first HARQ-ACK codebook, only the HARQ-ACK information corresponding to downlink signals other than the downlink signal corresponding to the canceled PUCCH (ie, the first PUCCH) is valid.

[0155] II) In an optional manner, when the first HARQ-ACK codebook is a second type of HARQ-ACK codebook, the correspondence between the bits in the first HARQ-ACK codebook and the downlink signal is determined based on the second target DAI of the downlink signal; wherein the second target DAI is the DAI of the downlink signal, wherein the counting of the DAI of the downlink signal starts from the first downlink signal of the multiple downlink signals corresponding to the first HARQ-ACK codebook and does not include the first downlink signal; or, the second target DAI is the DAI of the downlink signal minus the number of first PUCCHs whose transmission was canceled before the downlink signal, wherein the counting of the DAI of the downlink signal starts from the first downlink signal of the multiple downlink signals corresponding to the first HARQ-ACK codebook.

[0156] The above technical solution is illustrated below with reference to specific examples.

[0157] Example 5

[0158] 1. The terminal device receives a first downlink signal, and the HARQ-ACK information corresponding to the first downlink signal is transmitted through the first PUCCH.

[0159] 2. The terminal device receives a third downlink signal. The first uplink transmission channel corresponding to the third downlink signal overlaps with the time domain resources of the first PUCCH. The terminal device cancels transmission of the first PUCCH.

[0160] Optionally, the starting position of the time domain resources of the first downlink signal is before the starting position of the time domain resources of the third downlink signal.

[0161] 3. The terminal device receives the second downlink signal, and the HARQ-ACK information corresponding to the second downlink signal is transmitted through the second PUCCH.

[0162] The time domain resources of the second downlink signal are subsequent to the time domain resources of the third downlink signal, and the time domain resources of the second PUCCH and the first uplink transmission channel do not overlap.

[0163] The second PUCCH and the first PUCCH are in the same time unit (eg, time slot, sub-time slot) and have the same priority, so the second PUCCH and the first PUCCH correspond to the same HARQ-ACK codebook.

[0164] 4. The terminal device sends a first HARQ-ACK codebook through the second PUCCH. The first HARQ-ACK codebook includes the HARQ-ACK corresponding to the second downlink signal. Furthermore, the first HARQ-ACK codebook also includes placeholder information or HARQ-ACK information corresponding to all downlink signals belonging to the same HARQ-ACK codebook (i.e., the first HARQ-ACK codebook) before the first downlink signal.

[0165] The first HARQ-ACK codebook only includes HARQ-ACK information or placeholder information corresponding to other downlink signals other than the downlink signal corresponding to the canceled PUCCH (ie, the first PUCCH).

[0166] 1) If the first HARQ-ACK codebook belongs to the first type of HARQ-ACK codebook, the correspondence between each bit in the first HARQ-ACK codebook and the downlink signal is determined according to the semi-static configuration information (semi-static configuration information is used to determine the feedback timing set and the PDSCH time domain resource indication set, etc.).

[0167] In the first HARQ-ACK codebook, only HARQ-ACK information or placeholder information corresponding to downlink signals other than the downlink signal corresponding to the canceled PUCCH (ie, the first PUCCH) is valid.

[0168] 2) If the first HARQ-ACK codebook belongs to the second type of HARQ-ACK codebook, the correspondence between each bit in the first HARQ-ACK codebook and the downlink signal is determined according to the DAI. Specifically,

[0169] Method 1: The DAIs of other downlink signals (such as the second downlink signal) other than the downlink signal corresponding to the canceled PUCCH (i.e., the first PUCCH) are arranged in sequence. The correspondence between each bit in the first HARQ-ACK codebook and the downlink signal is directly determined based on the DAI of the downlink signal.

[0170] Method 2: Regardless of the downlink signal before or after the downlink signal corresponding to the canceled PUCCH (i.e., the first PUCCH), the DAI of the downlink signal corresponding to the same HARQ-ACK codebook (i.e., the first HARQ-ACK codebook) is arranged in sequence. The correspondence between the bits in the first HARQ-ACK codebook and the downlink signal is determined according to the DAI of the downlink signal and the number M of PUCCHs canceled before the downlink signal, for example, the DAI of the downlink signal minus the number M of PUCCHs canceled before the downlink signal.

[0171] Take the second type of HARQ-ACK codebook construction as an example, Figure 8 As shown, the three downlink signals corresponding to the first HARQ-ACK codebook correspond to three PDSCHs, namely PDSCH0, PDSCH1 and PDSCH2. Among them, the time domain resources of the PUCCH corresponding to PDSCH1 overlap with the PUCCH corresponding to PDSCH3, and the priority of the PUCCH corresponding to PDSCH1 is lower than the priority of the PUCCH corresponding to PDSCH3. Then, the PUCCH corresponding to PDSCH1 is deleted. The PUCCH corresponding to PDSCH2 is transmitted, and the first HARQ-ACK codebook carried in the PUCCH contains the HARQ-ACK information or placeholder information corresponding to PDSCH0 and the HARQ-ACK information corresponding to PDSCH2, among which PDSCH0 corresponds to DAI=0 and PDSCH2 corresponds to DAI=2.

[0172] Through the above technical solution, the additional transmission of the HARQ-ACK information of the downlink signal corresponding to the first PUCCH (that is, the PUCCH in which the time domain resources conflict) is avoided, thereby reducing the implementation complexity of the terminal device.

[0173] In an embodiment of the present application, the following technical solution is also provided: the terminal device receives a first downlink signal, and the HARQ-ACK information corresponding to the first downlink signal is transmitted through a first PUCCH; the terminal device cancels the transmission of the first PUCCH and does not expect to receive a second downlink signal, and the HARQ-ACK information corresponding to the second downlink signal is transmitted through a second PUCCH, wherein the second PUCCH and the first PUCCH correspond to the same HARQ-ACK codebook.

[0174] The above technical solution is illustrated below with reference to specific examples.

[0175] Example 6

[0176] 1. The terminal device receives a first downlink signal, and the HARQ-ACK information corresponding to the first downlink signal is transmitted through the first PUCCH.

[0177] 2. The terminal device receives a third downlink signal. The first uplink transmission channel corresponding to the third downlink signal overlaps with the time domain resources of the first PUCCH. The terminal device cancels transmission of the first PUCCH.

[0178] Optionally, the starting position of the time domain resources of the first downlink signal is before the starting position of the time domain resources of the third downlink signal.

[0179] 3. The terminal does not expect to receive the second downlink signal. The HARQ-ACK information corresponding to the second downlink signal is transmitted via the second PUCCH. The time domain position of the second downlink signal is after the time domain position of the third downlink signal, and the time domain resources of the second PUCCH and the first uplink transmission channel do not overlap. The second PUCCH and the first PUCCH are in the same time slot or sub-time slot and correspond to the same HARQ-ACK codebook.

[0180] The above technical solution can avoid redundant downlink retransmissions and reduce the implementation complexity of terminal equipment.
