[0003] Ultra Reliable and Low Latency Communication (URLLC) is a very important service type in 5th generation mobile networks or wireless systems (5G). URLLC services generally require very high reliability and very low latency. Another type of service is enhanced mobile broadband (eMBB), which generally requires higher speeds but does not require very low latency or very low error rates.

[0004] In the scenario where eMBB and URLLC services are running concurrently, the eMBB hybrid automatic repeat request acknowledgement (HARQ-ACK) information is usually transmitted using the long-format physical uplink control channel (PUCCH) resource, which is a PUCCH resource configured at the slot level; while the URLLC HARQ-ACK information is transmitted using the short-format PUCCH resource, which is a PUCCH resource configured at the subslot level.

[0073] 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.

[0074] 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 (UE). 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 communication device 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.

[0075] 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 an NG-RAN (New Generation-Radio Access Network). Alternatively, a machine type communication (MTC) system.

[0076] 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.

[0077] 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.

[0078] In some embodiments, E2E (End to End) connections may also be established between the 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).

[0079] In some embodiments, the wireless communication system may further include a network management device 13 .

[0080] 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 network side device (HSS). The embodiment of the present disclosure does not limit the implementation form of the network management device 13.

[0081] In 5G NR, highly reliable and low-latency (URLLC) services are a crucial service type, widely used in 5G scenarios such as factory automation, remote control, and augmented reality (AR) / virtual reality (VR). URLLC services typically require very high reliability and very low latency. Another type of service is enhanced mobile broadband (eMBB), which typically requires higher speeds but not very low latency or error rates.

[0082] In the relevant protocols, the PUCCH resources configured by the base station for the UE can have 5 formats, 0 to 4, which can be divided into two categories: long format and short format. The long format PUCCH resources occupy 4 to 14 time domain symbols, while the short format PUCCH resources occupy 1 to 2 time domain symbols. The advantage of the short format PUCCH is that it can reduce the PUCCH channel transmission time. Because the long format PUCCH resources occupy more time domain resources, under the condition of the same control information load, the number of resource blocks (RBs) occupied in the frequency domain can be reduced. And under the same coverage requirements, the transmit power to the UE can be reduced.

[0083] The current PUCCH resource configuration is divided into PUCCH resources configured at the slot level and PUCCH resources configured at the subslot level. PUCCH resources configured at the slot level, that is, the base station will configure up to 4 PUCCH resource sets for the UE in each slot, and each PUCCH resource set can carry a certain amount of uplink control information payload (UCI payload). The range of UCI payloads that can be carried by different PUCCH resources does not overlap. In the existing protocol, for slot-level PUCCH resource configuration, the UCI payload corresponding to PUCCH resource set 0 is 1 to 2 bits (bits), the UCI payload corresponding to PUCCH resource set 1 is 3 to N1 bits, the UCI payload corresponding to PUCCH resource set 2 is N1+1 to N2 bits, and the UCI payload corresponding to PUCCH resource set 3 is N2+1 to 1706 bits, where N1 and N2 are values ​​configurable by the base station. Each PUCCH resource set contains multiple PUCCH resources, which can be distinguished using a PUCCH resource identity (ID). The PUCCH resource configuration in different slots is the same. Each slot contains one Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) feedback opportunity.

[0084] Subslot-level PUCCH resource configuration involves dividing a slot into multiple subslots. PUCCH resources are configured on a subslot-by-subslot basis, meaning each subslot is configured with multiple PUCCH resource sets, and each PUCCH resource set contains multiple PUCCH resources. Each subslot has one HARQ-ACK feedback opportunity. This reduces HARQ-ACK feedback latency and better supports the low-latency characteristics of URLLC services.

[0085] In related technologies, a UE can determine the PUCCH resources used by a HARQ-ACK codebook, where a HARQ-ACK codebook consists of HARQ-ACK feedback information bits of one or more physical downlink shared channels (PDSCHs). The method by which a UE determines the PUCCH resources used by a HARQ-ACK codebook is as follows:

[0086] 1. The UE selects the corresponding PUCCH resource set based on the number of bits in the HARQ-ACK codebook;

[0087] 2. Determine the specific PUCCH resource based on the indication information in the last DCI among the multiple downlink scheduling DCIs corresponding to the multiple PDSCHs corresponding to the HARQ-ACK codebook. The resource indication includes two aspects: (1) the interval k1 between the slot / subslot where the PUCCH resource for transmitting HARQ-ACK is located and the slot / subslot where the PDSCH is located. k1 is in units of slot / subslot. If the slot / subslot where the PDSCH is located is n, the slot / subslot where the HARQ-ACK is located is n+k1; (2) the specific index of the PUCCH resource used by the HARQ-ACK information, that is, the PUCCH resource ID.

[0088] In scenarios where eMBB and URLLC services are running concurrently, eMBB HARQ-ACK information is usually transmitted using long-format PUCCH resources, which are configured at the slot level. URLLC HARQ-ACK information, on the other hand, is transmitted using short-format PUCCH resources, which are configured at the subslot level. In this case, one eMBB HARQ-ACK message may overlap with multiple URLLC HARQ-ACK messages in the time domain, causing a time domain conflict for the PUCCH resources. Therefore, multiple HARQ-ACK messages need to be multiplexed.

[0089] Based on the above wireless communication system, how to multiplex multiple HARQ-ACK information is proposed, and various embodiments of the disclosed method are proposed.

[0090] Figure 2 This is a flow chart of a method for determining resource reuse according to an exemplary embodiment, which is applied to the terminal side. Figure 2 As shown, the following steps are included.

[0091] In step S11, when it is determined that the first physical uplink control channel (PUCCH) resource of the hybrid automatic repeat request acknowledgement (HARQ-ACK) of the first type of service overlaps with the second PUCCH resource of the HARQ-ACK of the second type of service in the time domain, it is determined whether the first PUCCH resource and the second PUCCH resource meet the preset timing conditions in the time domain.

[0092] Exemplarily, the first type of service is eMBB service, and the second type of service is URLLC service.

[0093] As an implementation method, the preset timing condition includes:

[0094] The interval between the first time domain symbol and the second time domain symbol is greater than or equal to a preset value;

[0095] The first time domain symbol is a time domain symbol with the earliest starting position between the first PUCCH resource of the HARQ-ACK of the first type of service and the second PUCCH resource of the HARQ-ACK of the second type of service;

[0096] The second time domain symbol is the time domain symbol with the latest ending position between the PDSCH corresponding to the HARQ-ACK of the first type of service and the PDSCH corresponding to the HARQ-ACK of the second type of service.

[0097] Figure 3 The schematic diagram of the preset timing conditions is shown as follows: Figure 3 As shown, the time interval between the earliest starting symbol of the PUCCH resources of the HARQ-ACK of the first type of business and the latest ending symbol of the two PDSCHs corresponding to the two is T_gap, and the T_gap must be greater than or equal to the preset time interval T.

[0098] The preset time interval T may be predefined, and the preset time interval T may be related to parameters such as subcarrier spacing.

[0099] In step S12, if the preset timing condition is met, it is determined to perform resource multiplexing processing on the HARQ-ACK of the first type of service and the HARQ-ACK of the second type of service.

[0100] As an implementation method, the resource reuse process includes:

[0101] The HARQ-ACK information of the first type of service and the HARQ-ACK information of the second type of service are carried and transmitted on the same PUCCH resource.

[0102] In this way, by performing resource multiplexing processing on the HARQ-ACK of the first type of service and the HARQ-ACK of the second type of service, the time domain conflict of multiple PUCCH resources is resolved.

[0103] In the above solution, the method further includes:

[0104] A PUCCH resource configured at a subslot level is selected as the PUCCH resource carrying the HARQ-ACK information of the first type of service and the HARQ-ACK information of the second type of service.

[0105] When selecting PUCCH resources to carry multiplexed HARQ-ACK information, if slot-level configured PUCCH resources are used, the selected PUCCH resources may overlap in time domain with the URLLC HARQ-ACK PUCCH resources of the next subslot, resulting in a complex situation where multiplexing must be performed again. The advantage of using subslot-level configured PUCCH resources is that the PUCCH resources configured at the subslot level are all contained within one subslot, so the selected PUCCH resources will not overlap in time domain with the URLLC HARQ-ACK PUCCH resources of the next subslot.

[0106] As an implementation manner, selecting a PUCCH resource configured at a sub-slot level as a PUCCH resource carrying HARQ-ACK information of the first type of service and HARQ-ACK information of the second type of service includes:

[0107] According to the indication of the DCI corresponding to the HARQ-ACK information of the second type of service, a PUCCH resource is selected as the PUCCH resource carrying the HARQ-ACK information of the first type of service and the HARQ-ACK information of the second type of service.

[0108] As an implementation manner, selecting a PUCCH resource according to the DCI indication corresponding to the HARQ-ACK information of the second type of service as the PUCCH resource carrying the HARQ-ACK information of the first type of service and the HARQ-ACK information of the second type of service, including:

[0109] Determine a PUCCH resource set according to the number of bits of the HARQ-ACK information of the first type of service and the number of bits of the HARQ-ACK information of the second type of service;

[0110] According to the PUCCH resource identifier indicated by the DCI corresponding to the HARQ-ACK of the second type of service, the PUCCH resource used to transmit the HARQ-ACK information of the first type of service and the HARQ-ACK information of the second type of service is determined from the PUCCH resource set.

[0111] In this way, when determining to perform resource multiplexing processing on the HARQ-ACK of the first type of service and the HARQ-ACK of the second type of service, a selection method for selecting PUCCH resources for transmitting the multiplexed HARQ-ACK information is provided.

[0112] In the above solution, according to the PUCCH resource identifier indicated by the DCI corresponding to the HARQ-ACK of the second type of service, determining the PUCCH resource for transmitting the HARQ-ACK information of the first type of service and the HARQ-ACK information of the second type of service from the PUCCH resource set, including:

[0113] When the second PUCCH resources of the HARQ-ACK of two or more second-category services overlap with the first PUCCH resource of the HARQ-ACK of the first-category service in the time domain, the PUCCH resource for transmitting the HARQ-ACK information of the first-category service and the HARQ-ACK information of the second-category service is determined from the PUCCH resource set according to the PUCCH resource identifier indicated by the DCI corresponding to the first HARQ-ACK of the second-category service in time.

[0114] It should be noted that the time domain overlap may be partial overlap or complete overlap.

[0115] The technical solution described in the embodiment of the present disclosure determines that the HARQ-ACK of the first type of business and the HARQ-ACK of the second type of business are to be resource multiplexed when it is determined that the first PUCCH resource of the HARQ-ACK of the first type of business and the second PUCCH resource of the HARQ-ACK of the second type of business overlap in the time domain, and the first PUCCH resource and the second PUCCH resource meet the preset timing conditions in the time domain; in this way, by carrying the HARQ-ACK information of the first type of business and the HARQ-ACK information of the second type of business on the same PUCCH resource for transmission, the time domain conflict of multiple PUCCH resources is resolved.

[0116] The following takes the first type of service as eMBB service, the second type of service as URLLC service, and the preset value as 2 time intervals as an example to explain whether the preset timing conditions are met.

[0117] Figure 4 This is a schematic diagram showing the overlap of one eMBB HARQ-ACK message and multiple URLLC HARQ-ACK messages in the time domain according to an exemplary embodiment. Figure 1 ,like Figure 4 As shown, the eMBB's HARQ-ACK has time domain overlap with both the HARQ-ACK1 of the first URLLC and the HARQ-ACK2 of the second URLLC. Specifically, the eMBB's HARQ-ACK consists of 10 symbols, from 4 to 13. The HARQ-ACK1 of the first URLLC is symbol 6, and the HARQ-ACK2 of the second URLLC is symbol 13. Symbol 6 of symbols 4 to 13 occupied by the eMBB's HARQ-ACK overlaps with symbol 6 of the HARQ-ACK1 of the first URLLC in the time domain. Symbol 13 of symbols 4 to 13 occupied by the eMBB's HARQ-ACK overlaps with symbol 13 of the HARQ-ACK2 of the second URLLC in the time domain. The earliest starting time domain symbol in the PUCCH resources of the eMBB's HARQ-ACK and the PUCCH resources of the HARQ-ACK1 of the first URLLC is time domain symbol 4 of the eMBB's HARQ-ACK. Among them, the time domain symbols of the PDSCH corresponding to the HARQ-ACK of the eMBB are 1 to 6, the time domain symbols of the PDSCH corresponding to the HARQ-ACK1 of the first URLLC are time domain symbols 0 to 1, and the time domain symbol with the latest ending position between the two is the time domain symbol of the PDSCH of the DCI corresponding to the HARQ-ACK1 of the first URLLC, which is 1. Figure 4 It can be seen that the interval between symbol 4 of the HARQ-ACK of the eMBB and symbol 1 corresponding to the PDSCH of HARQ-ACK1 in the URLLC is 2 intervals, which meets the timing conditions.

[0118] Figure 5 This is a schematic diagram showing the overlap of one eMBB HARQ-ACK message and multiple URLLC HARQ-ACK messages in the time domain according to an exemplary embodiment. Figure 2 ,from Figure 5 It can be seen that the interval between symbol 3 of the HARQ-ACK of the eMBB and symbol 1 corresponding to the PDSCH of HARQ-ACK-1 in the URLLC is 1 interval, which does not meet the timing conditions.

[0119] Figure 6 This is a schematic diagram showing the overlap of one eMBB HARQ-ACK message and multiple URLLC HARQ-ACK messages in the time domain according to an exemplary embodiment. Figure 3 ,from Figure 6 It can be seen that the eMBB's HARQ-ACK has no time domain overlap with the first URLLC's HARQ-ACK1, and only has time domain overlap with the second URLLC's HARQ-ACK2. Specifically, the eMBB's HARQ-ACK is 7 symbols from 7 to 13, and the second URLLC's HARQ-ACK2 is symbol 13. Symbol 13 of the 7 to 13 symbols occupied by the eMBB's HARQ-ACK overlaps with symbol 13 of the second URLLC's HARQ-ACK2 in the time domain. Among them, the earliest starting time domain symbol in the PUCCH resources of the eMBB's HARQ-ACK and the PUCCH resources of the second URLLC's HARQ-ACK2 is time domain symbol 7 of the eMBB's HARQ-ACK. Among them, the time domain symbols of the PDSCH corresponding to the HARQ-ACK of the eMBB are 1 to 6, the time domain symbol of the PDSCH corresponding to the HARQ-ACK2 of the second URLLC is time domain symbol 1, and the time domain symbol with the latest ending position between the two is the time domain symbol of the PDSCH corresponding to the HARQ-ACK2 of the second URLLC is 1. Figure 6 It can be seen that the symbol 7 of the HARQ-ACK of the eMBB and the symbol 1 corresponding to the PDSCH of the HARQ-ACK-1 in the URLLC are separated by -1 intervals, which does not meet the timing conditions.

[0120] Continue with Figure 4 Take the following example to illustrate how to determine resource reuse. Figure 4 As shown in Figure 1, a slot is divided into two subslots. The time domain location of the PUCCH resource for an eMBB HARQ-ACK is symbols 4 to 13, which overlaps with the PUCCH resources for two URLLC HARQ-ACKs in the time domain. Assuming the preset time interval is 2 symbols, the UE multiplexes the HARQ-ACKs of eMBB and URLLC as follows:

[0121] 1. According to the time sequence of URLLC HARQ-ACK, determine whether the first URLLC HARQ-ACK and eMBB HARQ-ACK meet the timing conditions for multiplexing. If they meet the conditions, the two HARQ-ACK information can be multiplexed together. If not, the eMBB HARQ-ACK will be punctured by the URLLC HARQ-ACK information, or the eMBB HARQ-ACK will be discarded. Figure 4 For eMBB HARQ-ACK and the first URLLC HARQ-ACK, according to Figure 4 As shown in the diagram, it can be seen that the time interval T_gap is 2 symbols, which is exactly equal to the preset time interval T, so the eMBB HARQ-ACK and the first URLLC HARQ-ACK can meet the timing conditions of multiplexing, and the eMBB HARQ-ACK and the first URLLC HARQ-ACK can be multiplexed together.

[0122] 2. If the timing conditions for multiplexing are met, a PUCCH resource is selected from the PUCCH resources configured at the subslot level to carry the multiplexed HARQ-ACK information. That is, the PUCCH resource set is determined according to the number of bits of the multiplexed HARQ-ACK information; the interval between the subslot where the PUCCH resource for transmitting the multiplexed HARQ-ACK is located and the subslot where the PDSCH is located is determined according to the k1 value indicated by the DCI corresponding to the first URLLC HARQ-ACK. k1 is in units of subslots. If the subslot where the PDSCH is located is n, the subslot where the HARQ-ACK is located is n+k1; the specific index of the PUCCH resource used for the multiplexed HARQ-ACK information is determined according to the PUCCH resource ID indicated by the downlink scheduling DCI corresponding to the first URLLC HARQ-ACK.

[0123] When selecting multiplexing resources, if the PUCCH resources configured at the slot level are selected, the selected PUCCH resources may overlap in time domain with the URLLC HARQ-ACK PUCCH resources of the next subslot, resulting in a complex situation where multiplexing must be performed again. The advantage of using PUCCH resources configured at the subslot level is that the PUCCH resources configured at the subslot level are all contained within a subslot, so the selected PUCCH resources will not overlap in time domain with the URLLC HARQ-ACK PUCCH resources of the next subslot. Therefore, PUCCH resources configured at the subslot level are preferred as PUCCH resources that carry multiplexing HARQ-ACK information.

[0124] Figure 7 is a flow chart of an information demodulation method according to an exemplary embodiment, which is applied to a base station side. Figure 7 As shown, the following steps are included.

[0125] Step S21: When it is determined that the terminal meets the resource multiplexing condition, a PUCCH resource for simultaneously carrying the HARQ-ACK information of the first type of service and the HARQ-ACK information of the second type of service is determined.

[0126] In the above solution, the resource reuse conditions include:

[0127] The first PUCCH resource of HARQ-ACK for the first type of service overlaps with the second PUCCH resource of HARQ-ACK for the second type of service in the time domain, and the first PUCCH resource and the second PUCCH resource meet a preset timing condition in the time domain.

[0128] In the above solution, the preset timing conditions include:

[0129] The interval between the first time domain symbol and the second time domain symbol is greater than or equal to a preset value;

[0130] The first time domain symbol is a time domain symbol with the earliest starting position between the first PUCCH resource of the HARQ-ACK of the first type of service and the second PUCCH resource of the HARQ-ACK of the second type of service;

[0131] The second time domain symbol is the time domain symbol with the latest ending position between the PDSCH corresponding to the HARQ-ACK of the first type of service and the PDSCH corresponding to the HARQ-ACK of the second type of service.

[0132] In the above solution, determining the PUCCH resource for simultaneously carrying the HARQ-ACK information of the first type of service and the HARQ-ACK information of the second type of service includes:

[0133] Determine a PUCCH resource set according to the sum of the number of bits of the HARQ-ACK for the first type of service and the HARQ-ACK for the second type of service;

[0134] According to the PUCCH resource identifier indicated by the DCI corresponding to the HARQ-ACK of the second type of service, the PUCCH resource used to transmit the HARQ-ACK information of the first type of service and the HARQ-ACK information of the second type of service is determined from the PUCCH resource set.

[0135] In the above solution, the method further includes:

[0136] When it is determined that the terminal does not meet the resource reuse condition, the PUCCH resource set is determined according to the number of HARQ-ACK bits of the second type of service.

[0137] According to the PUCCH identifier indicated by the DCI of the HARQ-ACK of the second type of service, a PUCCH resource is determined from the PUCCH resource set, and the HARQ-ACK information of the second type of service is demodulated from the PUCCH resource.

[0138] If the base station determines that the terminal does not meet the resource reuse condition, the HARQ-ACK information of the first type of service is discarded or punctured, so the base station does not need to demodulate the information on the PUCCH resource where the HARQ-ACK of the first type of service is located.

[0139] Step S22: Demodulate the HARQ-ACK information of the first type of service and the HARQ-ACK information of the second type of service from the PUCCH resource.

[0140] In the technical solution described in this embodiment, when the base station determines that the terminal meets the resource multiplexing conditions, it can receive HARQ-ACK information from the corresponding PUCCH resource carrying multiplexing information and demodulate the HARQ-ACK information of the first type of service and the HARQ-ACK information of the first type of service.
