Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to a method, apparatus and readable storage medium for transmitting hybrid automatic repeat request-acknowledgement (HARQ-ACK). Background Technology

[0002] Currently, in new radio (NR), downlink data is carried on the physical downlink shared channel (PDSCH), and uplink data is carried on the physical uplink shared channel (PUSCH). Base station equipment schedules the PDSCH and PUSCH using downlink control information (DCI) carried on the physical downlink control channel (PDCCH).

[0003] To ensure scheduling flexibility, a single downlink control information (DCI) can schedule one PDSCH or PUSCH. With a sub-carrier space (SCS) of 960 kHz, the corresponding slot duration is 1 / 64 millisecond (ms). However, with larger sub-carrier spaces and shorter slot durations, scheduling each PDSCH using a separate DCI would result in excessively high DCI blind detection overhead.

[0004] In a multi-TTI (multi-transmission time interval) design, a single DCI can schedule multiple time slots of PDSCH or multiple time slots of PUSCH. An example from a multi-TTI PDSCH scheduling scenario illustrates this: a single DCI can schedule four PDSCHs, which correspond sequentially to four time slots or four PDSCH transmission times. These four PDSCHs can be used to transmit different data, i.e., to transmit different transport blocks (TBs). Employing a multi-TTI design reduces the number of DCIs, thereby reducing the complexity of blind detection DCIs for the UE.

[0005] In multi-TTI PDSCH scheduling scenarios, when user equipment feeds back HARQ-ACKs for multiple PDSCHs scheduled by a single DCI on the time-frequency resources of PUCCH, how to effectively utilize the time-frequency resources of PUCCH is a problem that needs to be solved.

[0064] The embodiments of this disclosure will now be further described in conjunction with the accompanying drawings and specific implementation details.

[0065] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0066] like Figure 1 As shown, the method for transmitting HARQ-ACK provided in this embodiment can be applied to a wireless communication system 100, which may include a terminal device 101 and a network device 102. The terminal device 101 is configured to support carrier aggregation and can be connected to multiple carrier units of the network device 102, including a primary carrier unit and one or more secondary carrier units.

[0067] It should be understood that the wireless communication system 100 described above is applicable to both low-frequency and high-frequency scenarios. Application scenarios for the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access network (CRAN) systems, future 5th-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile network (PLMN) systems.

[0068] The terminal device 101 shown above can be user equipment (UE), terminal, access terminal, terminal unit, terminal station, mobile station (MS), remote station, remote terminal, mobile terminal, wireless communication equipment, terminal agent, or other terminal equipment. This terminal device 101 may have wireless transceiver capabilities, enabling it to communicate (e.g., wirelessly) with one or more network devices in one or more communication systems, and to receive network services provided by the network devices. These network devices include, but are not limited to, the network device 102 shown in the figure.

[0069] Among them, terminal device 101 may be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA) device, handheld device with wireless communication function, computing device or other processing device connected to a wireless modem, vehicle device, wearable device, terminal device in future 5G network or terminal device in future evolved PLMN network, etc.

[0070] Network device 102 can be an access network device (or access point). Access network device refers to equipment that provides network access functionality, such as a radio access network (RAN) base station. Specifically, network device 102 may include a base station (BS), or a base station and radio resource management equipment used to control the base station. Network device 102 may also include relay stations (relay equipment), access points, and base stations in future 5G networks, base stations in future evolved PLMN networks, or NR base stations. Network device 102 can be a wearable device or an in-vehicle device. Network device 102 can also be a communication chip with a communication module.

[0071] For example, network equipment 102 includes, but is not limited to: next-generation base stations (gnodeB, gNB) in 5G, evolved node B (eNB) in LTE systems, radio network controllers (RNC), node B (NB) in WCDMA systems, radio controllers and base station controllers (BSC) in CRAN systems, base transceiver stations (BTS) in GSM or CDMA systems, home base stations (e.g., home evolved nodeB, or home node B, HNB), baseband units (BBU), transmitting and receiving points (TRP), transmitting points (TP), or mobile switching centers, etc.

[0072] In multi-TTI PDSCH scheduling scenarios, when user equipment 101 feeds back HARQ-ACKs for multiple PDSCHs scheduled by a single DCI on the time-frequency resources of a PUCCH, it can feed back all HARQ-ACKs for multiple PDSCHs scheduled by the same DCI on the same PUCCH. Specifically, the time slot of the PUCCH used for feeding back HARQ-ACKs for multiple PDSCHs is determined based on k1 indicated in the DCI and the time slot position of the last PDSCH. Feeding back on the same PUCCH reduces resource overhead, but it also introduces additional feedback latency. This problem is particularly severe for PDSCHs with earlier time domain positions in multi-TTI PDSCHs. Therefore, feeding back on the same PUCCH cannot meet the needs of services with high latency requirements, such as ultra-reliable low-latency communication (URLLC) services.

[0073] This disclosure introduces a method of feedback on different PUCCHs in multi-TTI PDSCH scheduling scenarios, that is, HARQ-ACKs for multiple PDSCHs scheduled for the same DCI are fed back on different PUCCHs. By adopting the method of feedback on different PUCCHs, feedback latency can be reduced.

[0074] This disclosure supports user equipment 101 in using different HARQ-ACK transmission methods in different scenarios. The HARQ-ACK transmission methods include a first transmission method and a second transmission method. The first transmission method corresponds to sending multiple HARQ-ACKs on different PUCCHs, while the second transmission method corresponds to sending multiple HARQ-ACKs on the same PUCCH. When using the first transmission method, user equipment 101 can save resource overhead; when using the second transmission method, it can reduce feedback latency.

[0075] This disclosure provides a method for transmitting HARQ-ACK. (Refer to...) Figure 2 , Figure 2 This is a flowchart illustrating a method for transmitting HARQ-ACK according to an exemplary embodiment, such as... Figure 2 As shown, this method includes:

[0076] Step S21, network device 102 sends information to user equipment 101 to indicate the HARQ-ACK transmission method; wherein, the HARQ-ACK transmission method is a first transmission method or a second transmission method, the first transmission method corresponds to sending multiple HARQ-ACKs on different physical uplink control channels (PUCCH), and the second transmission method corresponds to sending multiple HARQ-ACKs on the same PUCCH.

[0077] Step S22: User equipment 101 receives information from network equipment indicating the HARQ-ACK transmission method. Based on the information indicating the HARQ-ACK transmission method, the HARQ-ACK transmission method is determined.

[0078] Step S23: User equipment 101 sends HARQ-ACK to network device 102 via the HARQ-ACK sending method.

[0079] In step S24, network device 102 receives HARQ-ACK from user equipment 101.

[0080] In some possible implementations, the HARQ-ACK sent by user equipment 101 to network device 102 in step S23 via the HARQ-ACK sending method is multiple HARQ-ACKs for multiple PDSCHs scheduled by the same DCI.

[0081] This disclosure provides a method for receiving HARQ-ACK, which is performed by a network device 102, and includes:

[0082] Information indicating the HARQ-ACK transmission method is sent to user equipment 101; wherein the HARQ-ACK transmission method is a first transmission method or a second transmission method, the first transmission method corresponds to sending multiple HARQ-ACKs on different physical uplink control channels (PUCCH), and the second transmission method corresponds to sending multiple HARQ-ACKs on the same PUCCH.

[0083] Receive HARQ-ACK from the user equipment 101.

[0084] In some possible embodiments, the multiple HARQ-ACKs received by network device 102 from user equipment 101 are multiple HARQ-ACKs for multiple PDSCHs scheduled under the same DCI. That is, the multiple HARQ-ACKs sent by user equipment 101 are multiple HARQ-ACKs for multiple PDSCHs scheduled under the same DCI.

[0085] In this embodiment of the present disclosure, the network device 102 sends information to the user equipment 101 to indicate the HARQ-ACK transmission method, so that the user equipment 101 determines the HARQ-ACK transmission method as the first transmission method or the second transmission method according to the instruction of the network device. This allows the user equipment 101 to adopt different HARQ-ACK transmission methods for different usage scenarios, thereby reducing the PUCCH time and frequency resource overhead and saving feedback latency.

[0086] This disclosure provides a method for receiving HARQ-ACK, which is performed by a network device 102, and includes:

[0087] Information indicating the HARQ-ACK transmission method is sent to user equipment 101; wherein the HARQ-ACK transmission method is a first transmission method or a second transmission method, the first transmission method corresponds to sending multiple HARQ-ACKs on different physical uplink control channels (PUCCH), and the second transmission method corresponds to sending multiple HARQ-ACKs on the same PUCCH.

[0088] The information used to indicate the HARQ-ACK transmission method includes: first auxiliary information for determining the HARQ-ACK transmission method, wherein the first auxiliary information is information in higher-layer signaling indicating that a first transmission method is used for HARQ-ACK of the first priority.

[0089] Receive HARQ-ACK from the user equipment.

[0090] In some possible implementations, HARQ-ACK priority includes two priorities: high priority and low priority. The first priority refers to high priority.

[0091] In some possible implementations, HARQ-ACK has three priorities: high, medium, and low. The first priority is high.

[0092] In some possible implementations, HARQ-ACK has more than three priorities. The first priority is the highest priority.

[0093] In some possible implementations, the first priority is the highest priority among the multiple priorities of HARQ-ACK.

[0094] In this embodiment of the present disclosure, network device 102 sends first auxiliary information to user equipment 101 for determining the HARQ-ACK transmission method. The first auxiliary information indicates that the first transmission method should be used for HARQ-ACK with a first priority. After the user equipment 101 determines the priority of the HARQ-ACK, it determines whether the priority of the HARQ-ACK meets the first priority required by the first auxiliary information according to the instruction. If it meets the first priority, it determines to use the first transmission method. If it does not meet the first priority, it determines to use the second transmission method, thereby selecting the HARQ-ACK transmission method that meets the requirements of network device 102.

[0095] This disclosure provides a method for receiving HARQ-ACK, which is performed by a network device 102, and includes:

[0096] Information indicating the HARQ-ACK transmission method is sent to user equipment 101; wherein the HARQ-ACK transmission method is a first transmission method or a second transmission method, the first transmission method corresponds to sending multiple HARQ-ACKs on different physical uplink control channels (PUCCH), and the second transmission method corresponds to sending multiple HARQ-ACKs on the same PUCCH.

[0097] The information used to indicate the HARQ-ACK transmission method includes: first auxiliary information for determining the HARQ-ACK transmission method, wherein the first auxiliary information is information in higher-layer signaling indicating that a first transmission method is used for HARQ-ACKs with higher priority than the first priority.

[0098] Receive HARQ-ACK from the user equipment 101.

[0099] In some possible implementations, HARQ-ACK has three priorities: high, medium, and low. The first priority is medium.

[0100] In some possible implementations, HARQ-ACK priority includes more than three priorities. The first priority is the second highest priority, or the first priority is a priority other than the highest, lowest, and second highest priorities.

[0101] In some possible implementations, the first priority is the second highest priority among the priorities of multiple HARQ-ACKs.

[0102] In this embodiment of the present disclosure, network device 102 sends first auxiliary information to user equipment 101 for determining the HARQ-ACK transmission method. The first auxiliary information indicates that a first transmission method should be used for HARQ-ACKs with a higher priority than the first priority. After user equipment 101 determines the priority of HARQ-ACK, it determines whether the priority of HARQ-ACK meets the first priority required by the first auxiliary information according to the instruction. If it meets the first priority, it determines to use the first transmission method. If it does not meet the first priority, it determines to use the second transmission method, thereby selecting the HARQ-ACK transmission method that meets the requirements of network device 102.

[0103] This disclosure provides a method for receiving HARQ-ACK, which is performed by a network device 102, and includes:

[0104] Information indicating the HARQ-ACK transmission method is sent to user equipment 101; wherein the HARQ-ACK transmission method is a first transmission method or a second transmission method, the first transmission method corresponds to sending multiple HARQ-ACKs on different physical uplink control channels (PUCCH), and the second transmission method corresponds to sending multiple HARQ-ACKs on the same PUCCH.

[0105] The information used to indicate the HARQ-ACK transmission method includes: first auxiliary information for determining the HARQ-ACK transmission method and second auxiliary information for determining the HARQ-ACK transmission method. The first auxiliary information is information in higher-layer signaling indicating that a first transmission method should be used for HARQ-ACKs with a first priority. The second auxiliary information is priority information indicated by the priority indication information field in the downlink control information (DCI), where the priority information represents the priority of the HARQ-ACKs corresponding to the multiple PDSCHs scheduled by the DCI.

[0106] Receive HARQ-ACK from the user equipment 101.

[0107] In one possible embodiment, the priority of the second auxiliary information indication is the first priority, which is equivalent to instructing the user equipment to use the first transmission method.

[0108] In one possible embodiment, the priority indicated by the second auxiliary information is not the first priority, which is equivalent to instructing the user equipment to use the second transmission method.

[0109] In this embodiment of the present disclosure, network device 102 sends first auxiliary information and second auxiliary information to user equipment 101 for determining the HARQ-ACK transmission method. The first auxiliary information indicates that the first transmission method is used for HARQ-ACK with a first priority, and the second auxiliary information indicates the priority of HARQ-ACK corresponding to the multiple PDSCHs scheduled by the DCI.
