[0099] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0100] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the embodiments of the present disclosure.

[0101] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the words "if" and "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0102] In order to better describe any embodiment of the present disclosure, an embodiment of the present disclosure is illustratively described by taking an application scenario of access control as an example.

[0103] Please refer to Figure 1 , which shows a schematic structural diagram of a wireless communication system provided by an embodiment of the present disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: several terminals 11 and several base stations 12.

[0104] Terminal 11 may refer to a device that provides voice and / or data connectivity to a user. Terminal 11 may communicate with one or more core networks via a radio access network (RAN). Terminal 11 may be an IoT terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, the terminal may be a fixed, portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (terminal). Alternatively, terminal 11 may be a device on an unmanned aerial vehicle (UAV). Alternatively, terminal 11 may be an in-vehicle device, such as a vehicle-mounted computer with wireless communication capabilities, or a wireless terminal connected to an external vehicle-mounted computer. Alternatively, the terminal 11 may also be a roadside device, for example, a street lamp, a traffic light or other roadside device with a wireless communication function.

[0105] The base station 12 may be a network-side device in a wireless communication system. The wireless communication system may be a fourth-generation mobile communication technology (4G) system, also known as a long-term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next-generation system of the 5G system. The access network in the 5G system may be referred to as a New Generation-Radio Access Network (NG-RAN).

[0106] Among them, the base station 12 can be an evolved base station (eNB) adopted in a 4G system. Alternatively, the base station 12 can also be a base station (gNB) adopting a centralized distributed architecture in a 5G system. When the base station 12 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU). The centralized unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link layer control protocol (RLC) layer, and a media access control (MAC) layer; the distributed unit is provided with a physical (PHY) layer protocol stack. The embodiment of the present disclosure does not limit the specific implementation method of the base station 12.

[0107] A wireless connection can be established between the base station 12 and the terminal 11 via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

[0108] In some embodiments, E2E (End to End) connections can also be established between terminals 11. For example, in vehicle-to-everything (V2X) communication scenarios such as V2V (vehicle to vehicle), V2I (vehicle to infrastructure), and V2P (vehicle to pedestrian).

[0109] In some embodiments, the wireless communication system may further include a network management device 13 .

[0110] Several base stations 12 are respectively connected to a network management device 13. The network management device 13 can be a core network device in a wireless communication system. For example, the network management device 13 can be a mobility management entity (MME) in an evolved packet core (EPC). Alternatively, the network management device can also be other core network devices, such as a serving gateway (SGW), a public data network gateway (PGW), a policy and charging rules function (PCRF), or a home subscriber server (HSS). The embodiment of the present disclosure does not limit the implementation form of the network management device 13.

[0111] URLLC is one of several different use cases supported by the 5G NR standard, specified by 3GPP. URLLC will enable a variety of advanced services for low-latency-sensitive connected devices, such as factory automation, autonomous driving, the Industrial Internet, smart grids, or robotic surgery. Other services that 5G will support include eMBB (Enhanced Mobile Broadband) and mMTC (Massive Machine Type Communication). eMBB will provide high-bandwidth internet access for wireless connectivity, large-scale video streaming, and virtual reality. mMTC is used to support network access for sensing, metering, and monitoring devices.

[0112] A key feature of URLLC is LL (Low Latency), which is crucial for devices such as autonomous driving and robotic surgery. Low latency allows optimized networks to process incredibly large amounts of data with minimal delay, and networks need to adapt to large amounts of data that changes in real time. This new URLLC wireless connection guarantees latency of 1ms or less. The design of low-latency and high-reliability services involves several technologies: an integrated frame structure, shorter cycle times, efficient control and data resource sharing, unlicensed uplink transmission, and a highly reliable channel coding scheme.

[0113] In URLLC, high-priority services have the right to be transmitted before low-priority services. In some embodiments, when HP-UCI (High Priority UCI, high-priority uplink control information) and LP-UCI (Low Priority UCI, low-priority uplink control information) generate resource conflicts, all LP-UCI information can be discarded. Figure 2 As shown, because the LP-UCI and HP-UCI transmissions are triggered at the same time after the DCI and PDSCH (Physical Downlink Shared Channel) transmissions, the feedback information corresponding to HARQ process numbers 1, 2, and 3 in the LP-UCI is discarded and no longer transmitted at that time. This can significantly impact the performance of LP services, especially when the LP-HARQ feedback information is discarded.

[0114] Those skilled in the art will appreciate that the technical solution may be implemented alone or together with any other technical solution in the embodiments of the present disclosure, and the embodiments of the present disclosure are not limited thereto.

[0115] like Figure 3 As shown, an embodiment of the present disclosure provides a method for retransmitting low-priority uplink information, which is applied in a base station and includes:

[0116] Step S101: In response to a UCI with a transmission conflict, use scheduling information of a high-priority UCI to deliver identification information of a low-priority UCI to be retransmitted by a terminal in the UCI with the transmission conflict.

[0117] In the embodiments of the present disclosure, the terminal may be various UEs with communication functions, including production equipment, vehicle-mounted equipment, intelligent robots, and various mobile phones.

[0118] Here, because the base station determines the time-frequency resource locations for transmitting the UCI reported by the terminal, the base station can pre-know the UCI transmission conflicts before receiving the UCI. If the base station determines that there are UCI transmission conflicts, it can inform the terminal which UCI needs to be retransmitted by the terminal.

[0119] In the embodiment of the present disclosure, the identification information of the UCI may be information such as a process number contained in the UCI itself, or may be identification information obtained by the base station by numbering the UCI to be retransmitted. The UCI to be retransmitted by the terminal includes at least HARQ information to be retransmitted.

[0120] In the embodiment of the present disclosure, when a transmission conflicting UCI is generated, the conflicting UCI may be divided into a high-priority UCI and a low-priority UCI according to service priorities.

[0121] In the embodiment of the present disclosure, when scheduling a high-priority UCI, the base station may use scheduling information to send down the identification information of the corresponding low-priority UCI. For example, when the base station schedules through downlink control information, the identification information is carried in the downlink control information.

[0122] In this way, when there is a transmission conflict with UCI, the base station can inform the terminal of the identifier of the UCI that needs to be retransmitted, thereby facilitating the terminal's retransmission of the UCI. This ensures that the base station and the terminal have consistent information about whether a transmission conflict exists and which UCI the terminal needs to retransmit, reducing information omissions caused by inconsistent information. Furthermore, it facilitates the terminal's retransmission of UCI based on the base station's instructions. Compared to retransmitting all process information at once, this reduces retransmission information redundancy and conserves resources.

[0123] The present disclosure provides an uplink information transmission method. The method, in response to uplink control information (UCI) with a transmission conflict, uses scheduling information of a high-priority UCI to transmit identification information of a low-priority UCI to be retransmitted by a terminal in the UCI with the transmission conflict, including:

[0124] In response to the UCI with transmission conflict, when it is determined to discard the low-priority UCI, first downlink control information DCI carrying identification information of the low-priority UCI is sent; wherein the first DCI is used to schedule the high-priority UCI.

[0125] In the disclosed embodiment, the base station schedules high-priority UCI by sending a first DCI to the terminal. Since the base station now knows that the conflicting low-priority UCI needs to be retransmitted by the terminal, it can number the low-priority UCI to be retransmitted by the terminal, that is, determine the identification information corresponding to the low-priority UCI. The base station can then carry this identification information in the first DCI and send it to the base station. The terminal can then perform uplink transmission based on the base station's scheduling and, based on the first DCI used to schedule the uplink transmission, determine the UCI to be retransmitted by the terminal and then retransmit it.

[0126] In this way, the base station and the terminal reach a consensus on the UCI to be retransmitted, thereby reducing information omission or unnecessary retransmission.

[0127] The present disclosure proposes an uplink information transmission method, wherein the first DCI includes: a first DAI field; the first DAI field is a field added in the first DCI, and is used to carry identification information of the low-priority UCI.

[0128] The first DCI is used to schedule the high-priority UCI, and therefore includes scheduling information of the high-priority UCI, such as the identifier of the high-priority UCI and configured time-frequency resources.

[0129] In the embodiment of the present disclosure, a first DAI field is added to the first DCI, which is used to carry the identification information of the low priority. In this way, the terminal can know which low-priority UCI needs to be retransmitted by reading the first DAI field in the first DCI.

[0130] In the embodiment of the present disclosure, the first DCI is used to schedule high-priority UCI. Therefore, the first DAI field may be carried in the first DCI corresponding to each high-priority UCI with a transmission conflict.

[0131] In this way, when the terminal receives the first DCI scheduling the high-priority UCI, it can know whether there is a corresponding low-priority UCI that needs to be retransmitted, and then complete the retransmission.

[0132] The present disclosure proposes a method for transmitting uplink information, the method further comprising:

[0133] Receive the high-priority UCI based on the first DCI scheduling.

[0134] After sending the high-priority UCI to the terminal, the base station receives the high-priority UCI reported by the terminal based on the first DCI. Simultaneously, the base station also sends the DCI for scheduling the low-priority UCI, and thus also receives the low-priority UCI reported by the terminal. If there is a transmission conflict between the high-priority UCI and the low-priority UCI, the terminal transmits the high-priority UCI and discards the low-priority UCI. In this case, the discarded low-priority UCI needs to be retransmitted by the terminal.

[0135] This disclosure proposes a method for transmitting uplink information. Figure 4 As shown, the method includes:

[0136] Step S201: Send a second DCI carrying indication information of the low-priority UCI to be retransmitted by the terminal; the second DCI is used to trigger the terminal to retransmit the low-priority UCI.

[0137] Here, the second DCI is used to trigger the terminal to report the codebook for one-time retransmission, wherein the second DCI carries indication information, which is used to indicate relevant information of the UCI to be retransmitted by the terminal, and is used for the terminal to confirm whether the UCI to be retransmitted is consistent with the UCI expected to be retransmitted by the base station. For example, the indication information can be used to indicate the number of UCI to be retransmitted by the terminal, or to indicate the identifier of the UCI to be retransmitted by the terminal, such as indicating the time-frequency resources configured for the UCI to be retransmitted by the terminal.

[0138] That is, when the base station triggers the terminal to retransmit via the second DCI, it uses the indication information therein to inform the terminal of information related to the retransmitted UCI. In this way, the base station and the terminal can reach a consensus on the UCI to be retransmitted by the terminal through the indication information, reducing information omissions or unnecessary retransmissions caused by inconsistent information between the base station and the terminal.

[0139] The present disclosure proposes an uplink information transmission method, where the second DCI includes: a second DAI field; the second DAI field is a field added in the second DCI and is used to carry the indication information.

[0140] In the embodiment of the present disclosure, the above indication information is carried by adding a second DAI field in the second DCI.

[0141] In one embodiment, the DAI field is used to inform the UE how many subframes in the HARQ feedback window contain downlink transmissions. Here, the DAI field can be used to inform the UE how many UCI codebooks need to be retransmitted due to transmission conflicts.

[0142] The present disclosure proposes a method for transmitting uplink information, wherein the indication information includes at least one of the following:

[0143] The number of low-priority UCIs to be retransmitted by the terminal;

[0144] PUCCH resource information configured for the low-priority UCI to be retransmitted by the terminal.

[0145] The above-mentioned indication information may include the number of UCI to be retransmitted by the terminal. In this way, the terminal obtains the identification information of the UCI to be retransmitted by the terminal based on the scheduling information of the high-priority UCI, that is, the first DCI, and determines the number of UCI to be retransmitted based on the indication information, so that the base station and the terminal reach a consensus on the retransmitted codebook.

[0146] In addition, the above indication information may further include PUCCH resource configuration for retransmission by the terminal, and the terminal may use the configured PUCCH resources to retransmit the above UCI.

[0147] This disclosure proposes a method for transmitting uplink information. Figure 5 As shown, the method includes:

[0148] Step S301: Receive retransmission information reported by the terminal based on the identification information; wherein the retransmission information at least includes the low-priority UCI to be retransmitted by the terminal.

[0149] After the terminal determines the low-priority UCI to be retransmitted according to the identification information, it can retransmit it. Therefore, the base station can receive the retransmission information reported by the terminal based on the identification information.

[0150] Here, the retransmission information at least includes the UCI to be retransmitted determined based on the above identification information. In addition, the retransmission information may also include some other information, such as an identification, quantity information, and some verification information that facilitates the base station to identify the retransmission information.

[0151] The present disclosure proposes an uplink information transmission method, wherein the retransmission information further includes:

[0152] Bitmap information corresponding to the UCI to be retransmitted by the terminal; the bitmap information is used to indicate whether the terminal has received the identification information corresponding to the low-priority UCI to be retransmitted by the terminal.

[0153] In the embodiment of the present disclosure, since the identification information can be obtained by the base station by numbering according to certain rules, for example, numbering in sequence starting from 0, which is represented in binary as: 00, 01, 10, etc. If the identification information received by the terminal is discontinuous, there may be missed detection. Therefore, the terminal can use bitmap information to indicate whether the identification information corresponding to each UCI to be retransmitted is received, and report the corresponding retransmitted UCI. In this way, the base station can determine whether the information retransmitted by the terminal received includes all UCI to be retransmitted, whether there is other redundant information, and whether there is missed transmission, etc., through the bitmap information, so as to perform further data transmission.

[0154] The present disclosure proposes an uplink information transmission method, wherein the number of characters in the bitmap information is the same as the number of low-priority UCIs to be retransmitted by the terminal.

[0155] Here, the bitmap information received by the base station may include the terminal marking the UCI corresponding to each number. For example, if the terminal receives DCI containing marking information of 00, 01, and 10, then when the terminal retransmits, the three bits of the bitmap information are respectively marked as 1 to indicate that the corresponding identification information has been received, that is, the bitmap information is 111. The retransmission information reported by the terminal also includes the codebooks corresponding to these three UCIs.

[0156] If the terminal receives DCI containing marking information 00 and 10, then the terminal has missed detecting the DCI with marking information 01. In this case, the 3-bit bitmap information reported by the terminal during retransmission is 101, which informs the base station that the identification information of the second UCI has not been received and that the UCI corresponding to 00 and 10 has been retransmitted.

[0157] In this way, the base station can learn whether the terminal has missed detection through the bitmap information, and determine the UCI retransmitted by the terminal and its corresponding identification information, so as to avoid misunderstanding.

[0158] like Figure 6 As shown, an embodiment of the present disclosure provides a method for retransmitting low-priority uplink information, which is applied to a terminal and includes:

[0159] Step S401: Receive identification information of low-priority UCI to be retransmitted by a terminal in UCI with transmission conflict, which is sent by a base station using scheduling information of high-priority UCI.

[0160] In the embodiment of the present disclosure, the identification information of the UCI may be information such as a process number contained in the UCI itself, or may be identification information obtained by the base station by numbering the UCI to be retransmitted.

[0161] When the terminal receives the identification information sent by the base station, it can determine which UCIs are to be retransmitted by the terminal, eliminating the need to retransmit all low-priority UCIs. This improves retransmission efficiency and reduces unnecessary retransmissions and missed transmissions. Furthermore, the terminal and base station can reach a consensus on the UCIs to be retransmitted, reducing inconsistencies between retransmitted information and the retransmitted information to be received by the base station due to missed detection by the terminal.

[0162] The present disclosure proposes an uplink information transmission method, wherein a receiving base station uses scheduling information of a high-priority UCI to send identification information of a low-priority UCI to be retransmitted by a terminal in a UCI with a transmission conflict, including:

[0163] A first DCI carrying identification information of the low-priority UCI is received; wherein the first DCI is used to schedule the high-priority UCI.

[0164] If the high-priority UCI and the low-priority UCI are transmitted to the base station at the same time, the base station will preferentially receive the high-priority UCI. Therefore, the base station can determine that the low-priority UCI is the UCI to be retransmitted by the terminal.

[0165] In this embodiment of the present disclosure, a terminal receives a first DCI scheduling high-priority UCI. Because the base station knows in advance that the terminal needs to retransmit conflicting low-priority UCI, it includes identification information corresponding to the low-priority UCI in the first DCI. The terminal can then perform uplink transmission based on the base station's scheduling and, based on the first DCI used to schedule the uplink transmission, determine the UCI to be retransmitted by the terminal and then retransmit it.

[0166] In this way, the base station and the terminal reach a consensus on the UCI to be retransmitted, thereby reducing information omission or unnecessary retransmission.

[0167] The present disclosure proposes an uplink information transmission method, where the first DCI includes: a first DAI field; the first DAI field is a field added in the first DCI, and is used to carry identification information corresponding to the low-priority UCI.

[0168] In the embodiment of the present disclosure, the first DCI carries a first DAI field, and the terminal can obtain identification information corresponding to the low-priority UCI through the first DAI field.

[0169] The present disclosure proposes a method for transmitting uplink information, the method further comprising:

[0170] Reporting the high-priority UCI based on the first DCI;

[0171] According to the identification information carried by the first DCI, the low-priority UCI is discarded and the low-priority UCI is used as the low-priority UCI to be retransmitted by the terminal.

[0172] Since the first DCI is downlink control information used to schedule high-priority UCI, the terminal may report the corresponding high-priority UCI based on the scheduling of the first DCI.

[0173] In addition, the first DCI carries identification information of the low-priority UCI to be retransmitted by the terminal. Therefore, the terminal can also retransmit the low-priority UCI based on the identification information.

[0174] The present disclosure proposes a method for transmitting uplink information, the method further comprising:

[0175] Receive a second DCI carrying indication information of the low-priority UCI to be retransmitted by the terminal; the second DCI is used to trigger the terminal to retransmit the low-priority UCI.

[0176] Here, the second DCI is used to trigger the terminal to report the codebook for one-time retransmission, wherein the second DCI carries indication information for indicating relevant information of the UCI to be retransmitted by the terminal. For example, the indication information can be used to indicate the number of UCI to be retransmitted by the terminal, or to indicate the identifier of the UCI to be retransmitted by the terminal, or to indicate the time-frequency resources configured for the UCI to be retransmitted by the terminal.

[0177] Therefore, the terminal can retransmit the UCI based on the received second DCI. Since the second DCI carries indication information, the terminal can further determine whether the UCI it retransmitted is consistent with the UCI to be retransmitted determined by the base station based on the indication information.

[0178] The present disclosure proposes an uplink information transmission method, where the second DCI includes: a second DAI field; the second DAI field is a field added in the second DCI, and carries the indication information.

[0179] Here, the second DAI field is used to carry the above indication information, for example, the numerical value carried by several characters identifies how many UCI codebooks need to be retransmitted due to transmission conflicts.

[0180] The present disclosure proposes a method for transmitting uplink information, wherein the indication information includes at least one of the following:

[0181] The number of low-priority UCIs to be retransmitted by the terminal;

[0182] PUCCH resource information configured for the low-priority UCI to be retransmitted by the terminal.

[0183] The above-mentioned indication information may include the number of UCI to be retransmitted by the terminal. In this way, the terminal obtains the identification information of the UCI to be retransmitted by the terminal based on the scheduling information of the high-priority UCI, that is, the first DCI, and determines the number of UCI to be retransmitted based on the indication information, so that the base station and the terminal reach a consensus on the retransmitted codebook.

[0184] In addition, the above indication information may further include PUCCH resource configuration for retransmission by the terminal, and the terminal may use the configured PUCCH resources to retransmit the above UCI.

[0185] The present disclosure proposes a method for transmitting uplink information, the method further comprising:

[0186] Retransmission information is reported based on the identification information; wherein the retransmission information at least includes: low-priority UCI retransmitted by the terminal.

[0187] After the terminal determines the UCI to be retransmitted according to the identification information, it can retransmit it. Of course, after receiving the second DCI sent by the base station for triggering the terminal to retransmit, the terminal reports the retransmission information based on the above identification information.

[0188] Here, the retransmission information at least includes the UCI to be retransmitted determined based on the above identification information. In addition, the retransmission information may also include some other information, such as an identification, quantity information, and some verification information that facilitates the base station to identify the retransmission information.

[0189] The present disclosure proposes an uplink information transmission method, wherein the retransmission information further includes:

[0190] Bitmap information corresponding to the low-priority UCI retransmitted by the terminal; the bitmap information is used to indicate whether the terminal has received identification information of the low-priority UCI to be retransmitted by the terminal.

[0191] In the embodiment of the present disclosure, since the identification information can be obtained by the base station by numbering according to certain rules, for example, numbering in sequence starting from 0, which is represented in binary as: 00, 01, 10, etc. If the identification information received by the terminal is discontinuous, there may be missed detection. Therefore, the terminal can use bitmap information to indicate whether the identification information corresponding to each UCI to be retransmitted is received, and report the corresponding retransmitted UCI. In this way, it is convenient for the base station to determine whether the information retransmitted by the terminal received includes all UCI to be retransmitted, whether there is other redundant information, and whether there is missed transmission, etc., through the bitmap information, so as to perform further data transmission.

[0192] The present disclosure proposes an uplink information transmission method, wherein the number of characters in the bitmap information is the same as the number of low-priority UCIs to be retransmitted by the terminal.

[0193] Here, the terminal can mark the UCI corresponding to each number. For example, if the terminal receives DCI containing marking information of 00, 01, and 10, then when the terminal retransmits, it records 1 in the 3-bit bitmap information to indicate that the corresponding identification information has been received, that is, the bitmap information is 111. The retransmission information reported by the terminal also includes the codebooks corresponding to these three UCIs.

[0194] If the terminal receives DCI containing marking information 00 and 10, then the terminal has missed detecting the DCI with marking information 01. In this case, the 3-bit bitmap information reported by the terminal during retransmission is 101, which informs the base station that the identification information of the second UCI has not been received and that the UCI corresponding to 00 and 10 has been retransmitted.

[0195] The present disclosure also provides the following examples:

[0196] In one embodiment, a one-shot codebook mechanism is used to retransmit HARQ information. According to the one-shot codebook rule, when the base station triggers the one-shot codebook feedback through Trig-DCI, that is, the second DCI mentioned above, the UE will sort the ACK / NACK information corresponding to all HARQ processes in ascending order according to the process number. Figure 7 The discarded HARQ information of process numbers 1, 2, and 3 is included in the one-time codebook and fed back.

[0197] However, in this way, if the discarded HARQ information only corresponds to part of the HARQ process, the ACK / NACK (acknowledgement / negative acknowledgement) information of other HARQ processes still needs to be fed back according to the one-time codebook rule, resulting in redundancy. Figure 7The HARQ information of process numbers 4-8 that are not discarded is also included in the one-time codebook and fed back. In addition, the Semi-Persistent Scheduling (SPS release) process does not have a corresponding process number and therefore cannot be included in the one-time codebook.

[0198] If you want to limit the feedback range of the one-time codebook to the discarded HARQ process, you will encounter the problem of UE missing HP-DCI detection. Figure 8 Based on its scheduling, the base station triggers HARQ retransmission and expects to receive UCI 1, 2, and 3. However, the UE misses the second HP-DCI and is unaware that UCI 2 should be discarded. Upon receiving the triggering DCI, the UE only returns UCI 1 and 3, resulting in a mismatch between the base station and UE regarding the retransmitted codebook.

[0199] In the embodiment of the present disclosure, a D-DAI (Drop-DAI, dropped downlink allocation index) field, that is, the above-mentioned first DAI field, is added to the DCI for scheduling HP data. The base station numbers the discarded LP codebook and sends the number to the UE. When the UE encounters a codebook discard situation, the dropped codebook will be cached (including the HARQ information of the semi-static scheduling release process without a corresponding process number) and wait for the opportunity to transmit again. In the Trig-DCI that triggers the one-time codebook, a TD-DAI (Total-Drop-DAI, total dropped downlink allocation index) field is added, that is, the above-mentioned second DAI field indicates the total number of dropped codebooks and explicitly specifies the corresponding PUCCH resources. When the base station sends Trig-DCI, that is, when the above-mentioned second DCI triggers the retransmission of HARQ, the UE transmits the cached codebook on the specified resource at one time according to the received number.

[0200] Therefore, this solution ensures that the base station and user end have consistent understanding of the codebook contents, resolving issues caused by missed DCI detection. Furthermore, compared to existing solutions, it eliminates redundant information in the HARQ retransmission codebook and supports the retransmission of feedback information corresponding to the semi-persistent scheduling release process. The disclosed embodiments include the following two aspects: identifying the discarded codebook number during scheduling, and providing one-time feedback on the discarded codebook upon triggering.

[0201] Numbering of discarded codebooks during scheduling: A D-DAI field is added to the DCI for scheduling HP data. The base station anticipates possible UCI conflicts when scheduling HP data. Therefore, the D-DAI field in the HP DCI is used to number discarded LP codebooks and notify the UE. When a codebook is discarded, the UE needs to cache the discarded codebook and wait for another transmission opportunity.

[0202] One-time feedback of lost codebooks upon triggering: In the Trig-DCI that triggers the one-time codebook, a TD-DAI field is added to indicate the total number of lost codebooks and explicitly specify the corresponding PUCCH resources. When the base station sends a Trig-DCI to trigger HARQ retransmission, the UE retransmits the cached codebooks according to the received number. The retransmitted codebook is synthesized to first contain TD-DAI bits, each corresponding to a discarded LP codebook. A value of 1 indicates that the UE has received the corresponding HPDCI and will include the corresponding LP codebook in the subsequent content of the retransmitted codebook.

[0203] like Figure 9 As shown, three consecutive LP-UCIs are discarded due to resource conflicts. In the corresponding HP-DCI, the D-DAI values are 00, 01, and 10, respectively, with increasing values representing the numbers of discarded UCIs 1, 2, and 3. The meaning of the D-DAI values is that D-DAI = 11 indicates no UCI conflict, and D-DAI = 00 / 01 / 10 represents the numbers of the corresponding LP codebooks that were discarded.

[0204] like Figure 10 As shown in Figure 1, in Trig-DCI, the TD-DAI value is 10, indicating that the total number of discarded UCIs is 3. Therefore, when synthesizing the retransmitted codebook, it first contains 3 bits, all with values of 1, indicating that the UE has received the corresponding HP DCI and will include the codebooks corresponding to UCIs 1, 2, and 3 in the subsequent content of the retransmitted codebook.

[0205] It should be noted that the above method supports feedback of HARQ information for SPS Release: When the UE encounters codebook loss, the lost codebook is cached, including the HARQ information for the semi-persistent scheduling release process without a corresponding process number. When the base station triggers retransmission, the HARQ information for the semi-persistent scheduling release process is fed back again along with the cached codebook.

[0206] Furthermore, regarding the determination of PUCCH resources, Trig-DCI should include, in addition to traditional PUCCH resource parameters, the PUCCH Resource Set ID to eliminate inconsistent resource selection between the base station and UE due to load changes caused by different codebook numbers. If there are remaining resources, the codebook can be padded with zeros after retransmission.

[0207] In addition to the above scenarios, the embodiment of the present disclosure can avoid the problem of HARQ feedback codebook ambiguity between the base station and the user when the UE misses HP-DCI. Figure 11 As shown in the figure, due to missed DCI detection, the UE is unaware that the second LP codebook has been discarded. When synthesizing the retransmitted codebook, the UE sets the second bit corresponding to the second LP codebook to 0 in the first 3 bits of the bitmap and directly concatenates the codebooks (UCI1 and UCI3) that the UE believes were discarded in subsequent codebooks. Upon receiving the retransmitted codebook, the base station first reads the first 3 bits of the bitmap and divides the subsequent retransmitted codebooks according to the size of the codebooks corresponding to the values 1 in the bitmap, thereby resolving the issue of missed DCI detection.

[0208] Through the technical solution of the embodiment of the present disclosure, an enhanced one-time codebook mechanism is provided for retransmitting discarded low-priority HARQ information. In the DCI that schedules HP data, a D-DAI field is added to number the discarded LP codebook. In the Trig-DCI that triggers the one-time codebook, a TD-DAI field is added to indicate the total number of discarded codebooks. When the base station sends Trig-DCI to trigger the retransmission of HARQ, the UE transmits the cached codebook on the designated resources at one time according to the received number. This mechanism eliminates the redundant information in the HARQ retransmission codebook while solving the problem of inconsistent understanding of the codebook content between the base station and the user end caused by DCI missed detection, and supports the retransmission of feedback information corresponding to the semi-persistent scheduling release process. On the one hand, it eliminates the redundant information in the HARQ retransmission codebook and solves the problem caused by DCI missed detection. At the same time, the HARQ retransmission codebook contains feedback corresponding to the semi-persistent scheduling release process.
