Description

Technical Field

[0001] The present application relates to the field of communication processing technology, and in particular to a HARQ-ACK feedback method and related products. Background Art

[0002] HARQ (Hybrid Automatic Repeat request) is a technology that combines FEC (Forward Error Correction) and ARQ (Automatic Repeat request) methods. FEC adds redundant information so that the receiving end can correct some errors, thereby reducing the number of retransmissions. For errors that FEC cannot correct, the receiving end will request the sending end to resend the data through the ARQ mechanism. The receiving end uses an error detection code, usually a CRC (Cyclic Redundancy Check) check, to detect whether the received data packet is erroneous. If there is no error, the receiving end will send a positive acknowledgment (ACK) to the sending end. After receiving the ACK, the sending end will continue to send the next data packet. If there is an error, the receiving end will discard the data packet and send a negative acknowledgment (NACK) to the sending end. After receiving the NACK, the sending end will resend the same data.

[0003] In existing communications, when the UE performs HARQ-ACK feedback, the confirmed PUCCH resources may not be available, resulting in the inability to provide HARQ-ACK feedback, which affects network performance. Summary of the invention

[0030] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0031] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article indicates that the associated objects before and after are in an "or" relationship.

[0032] The "multiple" that appears in the embodiments of the present application refers to two or more. The first, second, etc. descriptions that appear in the embodiments of the present application are only used for illustration and distinction of the description objects. There is no order, nor does it represent a special limitation on the number of devices in the embodiments of the present application, and cannot constitute any limitation on the embodiments of the present application. The "connection" that appears in the embodiments of the present application refers to various connection methods such as direct connection or indirect connection to achieve communication between devices, and the embodiments of the present application do not make any limitations on this.

[0033] The technical solution of the embodiment of the present application can be applied to Figure 1 The exemplary communication system 100 shown includes a terminal 110 and a network device 120 , wherein the terminal 110 is in communication connection with the network device 120 .

[0034] The example communication system 100 can be, for example: a Global System of Mobilecommunication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, an advanced long term evolution (LTE-A) system, a New Radio (NR) system, an evolved system of an NR system, an LTE system on an unlicensed spectrum (LTE-based access to unlicensed spectrum, LTE-U), an NR system on an unlicensed spectrum (NR-based access to unlicensed spectrum, NR-U), a Universal Mobile Telecommunication System (UMTS), a next generation communication system or other communication systems, etc.

[0035] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communications, but will also support, for example, device to device (Device to Device, D2D) communication, machine to machine (Machine to Machine, M2M) communication, machine type communication (Machine Type Communication, MTC), and vehicle to vehicle (Vehicle to Vehicle, V2V) communication, etc. The embodiments of the present application can also be applied to these communication systems.

[0036] The terminal 110 in the embodiment of the present application may refer to a user device, an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user device. The terminal may also be 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 function, a computing device or other processing device connected to a wireless modem, a relay device, a vehicle-mounted device, a wearable device, a terminal in a future 5G network or a terminal in a future evolved public land mobile communication network (PLMN), etc., and the embodiment of the present application is not limited to this.

[0037] The network device 120 in the embodiment of the present application may be a device for communicating with a terminal. The network device may be an evolved base station (evoledNodeB, eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (CRAN) scenario, or the network device may be a relay device, an access point, a vehicle-mounted device, a wearable device, and a network device in a future 5G network or a network device in a future evolved PLMN network, one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU), or a distributed unit (DU), etc., which is not limited in the embodiment of the present application.

[0038] In some deployments, the gNB may include a centralized unit (CU) and a DU. The gNB may also include an active antenna unit (AAU). The CU implements some of the functions of the gNB, and the DU implements some of the functions of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, and implements the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU is responsible for processing physical layer protocols and real-time services, and implements the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer.

[0039] HARQ-ACK timing (downlink data scheduling time)

[0040] See also Figure 2 , the downlink data scheduling time is just a schematic diagram. In 5G NR, K0 and K1 are both time slots. K0 represents the time interval between PDSCH (Physical Downlink Shared Channel) and PDCCH (Physical Downlink Control Channel). PDSCH is used to transmit downlink data, and PDCCH is used to transmit DCI (Downlink Control Information). K1 represents the time interval between HARQ-ACK feedback and PDSCH.

[0041] SPS (Semi-Persistent Scheduling) PDSCH

[0042] Semi-persistent scheduling in NR refers to semi-statically configuring radio resources and periodically allocating the resources to a specific UE. The PDCCH scrambled with SPS C-RNTI specifies the radio resources used by the UE (here referred to as SPS resources). After each cycle, the UE uses the SPS resources to receive or send data. The gNB does not need to re-send the PDCCH in this time slot to specify the allocated resources, reducing the corresponding PDCCH overhead. After the UE is configured with SPS, it cannot be used yet and must be activated using the PDCCH scrambled with CS-RNTI (Cell-Radio Network Temporary Identifier). The eNodeB activates / releases the UE's SPS through the PDCCH scrambled with SPS C-RNTI.

[0043] SPS PDSCH HARQ-ACK codebook

[0044] The gNB configures a maximum of 4 HARQ-ACK bit ranges for the UE, and configures a PUCCH resource in each range that can be used to feedback SPSPD SCH HARQ-ACK, that is, each HARQ-ACK bit range has a unique PUCCH resource.

[0045] When there is only SPS PDSCH HARQ-ACK feedback, and there is no HARQ-ACK feedback for scheduling PDCCH or SPS PDSCH to activate PDCCH or SPS PDSCH to deactivate PDCCH, if multiple SPS PDSCHs are configured, the HARQ-ACK bit order is: according to which SPS PDSCHs in this slot / subslot need to be carried by the PUCCH in this slot / subslot, determine all time slot or sub-time slot index sets, traverse each slot / subslot in this set, and arrange the HARQ-ACK in the downlink time slot of each {SPS configuration index, service cell index} in ascending order, then arrange the HARQ-ACK in the SPS configuration index of each service cell index in ascending order, and finally arrange them in ascending order of HARQ-ACK in the service cell index.

[0046] The UE determines the range of bits fed back by the SPS PDSCH HARQ-ACK on the PUCCH according to the number of bits fed back by the SPS PDSCH HARQ-ACK, and thus decides which PUCCH to use to feed back the SPS PDSCH HARQ-ACK.

[0047] See also Figure 3 , Figure 3 A HARQ-ACK feedback method is provided, which can be used in Figure 1 The communication system shown is implemented, for example, Figure 3The terminal 110 in the communication system shown may be a user equipment supporting NR, and the network device 120 may be a gNB. Of course, according to different network deployment requirements, the terminal 110 may be directly connected to the gNB through a wireless communication network. Of course, the terminal 110 may also be connected to the gNB through a TRP (Transmission and reception point). The TRP may be set to one or more according to different application scenarios. The specific structure of the communication system of the present application is only for the convenience of understanding the examples given, and the technical solution of the present application may not be limited to the following examples. Figure 1 The communication system architecture shown in FIG. 1 is a HARQ-ACK feedback method. Figure 3 As shown, the following steps are included:

[0048] Step S301: The network device sends configuration information to the UE, where the configuration information is used to indicate PUCCH resources.

[0049] Step S302: The UE receives configuration information sent by the network device;

[0050] Step S303: The network device sends an SPS PDSCH to the UE;

[0051] Step S304: The UE receives the SPS PDSCH sent by the network device, and determines the PUCCH resources available for the SPS PDSCH HARQ-ACK according to the configuration information.

[0052] For example, the available PUCCH resource may specifically be a single PUCCH resource, such as slot n, or may be a set of multiple PUCCH resources (ie, a PUCCH resource set).

[0053] For example, the above steps S302 and S304 may be combined to form a HARQ-ACK feedback method on the UE side, and the above steps S301 and S303 may be combined to form a HARQ-ACK feedback method on the network device side.

[0054] The UE of the HARQ-ACK feedback method provided in the present application determines the available PUCCH resources based on the configuration information of the network device, thereby avoiding the situation where the HARQ-ACK cannot be fed back due to the unavailability of the selected PUCCH resources, thereby improving the network reliability.

[0055] In an optional solution, when the UE determines that the PUCCH resource carrying the SPS PDSCH HARQ-ACK information of the SPS PDSCH is unavailable, the method may further include, before determining the PUCCH resource available for the SPS PDSCH HARQ-ACK according to the configuration information:

[0056] The UE receives DCI sent by the network device through the PDCCH, where the PUCCH resource indication field in the DCI is used to indicate a PUCCH index used to feed back the SPS PDSCH HARQ-ACK.

[0057] In another optional solution, when the UE determines that the PUCCH resource carrying the SPS PDSCH HARQ-ACK information of the SPS PDSCH is unavailable, the method may further include, before determining the PUCCH resource available for the SPS PDSCH HARQ-ACK according to the configuration information:

[0058] The UE receives downlink control information DCI sent by a network device through a PDCCH, where the DCI includes a time slot offset indicating a PUCCH resource available from a PDSCH to an SPS PDSCH HARQ-ACK.

[0059] In one alternative and in another alternative,

[0060] The above-mentioned PDCCH may be scrambled using the SPS PDSCH dedicated RNTI, the NDI of the DCI is set to 1, and the field in the DCI is set to a specific value. An example of the above-mentioned specific value may be shown in Table 1.

[0061] Table 1:

[0062]

[0063] There are many ways for the UE to determine that the PUCCH resource carrying the SPS PDSCH HARQ-ACK information of the SPS PDSCH is unavailable, such as Figure 4 An example approach is shown, see Figure 4 , Figure 4 In the example, the HARQ-ACK of the SPS PDSCH in slot n+2 needs to be fed back in slot n+5. However, since slot n+5 is full of downlink symbols, the UE cannot feed back the SPS PDSCH HARQ-ACK.

[0064] Optionally, the above configuration information may include: multiple HARQ-ACK bit ranges configured for the UE, each HARQ-ACK bit range includes an SPS PUCCH resource set, and the SPS PUCCH resource set includes at least two SPS PUCCH resources.

[0065] Optionally, the UE determining, according to the configuration information, the PUCCH resources available for the SPS PDSCH HARQ-ACK may specifically include:

[0066] The UE determines the first SPS PUCCH resource set corresponding to the total number of comparisons based on the total number of bits, and determines whether the SPS PUCCH resources in the first SPS PUCCH resource set are available according to the identification index. If the index0 SPS PUCCH resource is available, the available PUCCH resource is determined to be the index0 SPS PUCCH resource. If the index0 SPS PUCCH resource is determined to be unavailable, it is determined whether the SPS PUCCH after the index0 SPS PUCCH is available, for example, it is determined whether the index1 SPS PUCCH resource is available. If the index1 SPS PUCCH resource is available, it is determined that the available PUCCH resource is the index1 SPS PUCCH resource. If the index1 SPS PUCCH resource is unavailable, then the judgment is continued until the available SPS PUCCH resource is determined.

[0067] Embodiment 1

[0068] Embodiment 1 of the present application provides a HARQ-ACK feedback method. The method can be used in Figure 1 The method is implemented in the communication system shown in FIG. Figure 5 As shown, the following steps are included:

[0069] Step S501: A network device sends configuration information to a UE, where the configuration information is used to indicate a PUCCH resource.

[0070] Step S502: The network device sends an SPS PUSCH to the UE;

[0071] Step S503: When the UE determines that the PUCCH resource carrying the SPS PDSCH HARQ-ACK information of the SPS PDSCH is unavailable, the UE receives the DCI sent by the network device through the PDCCH;

[0072] The above-mentioned PDCCH can be scrambled by CS-RNTI, the NDI in the above-mentioned DCI is set to 1, and the field in the DCI is set to a specific value. The above-mentioned specific value can be shown in the above-mentioned Table 1.

[0073] Step S504: The UE determines available PUCCH resources according to the DCI and configuration information.

[0074] For example, the implementation of step S504 may specifically include:

[0075] The UE determines the PUCCH index for feeding back the SPS PDSCH HARQ-ACK according to the PUCCH resource indication field in the DCI, that is, the PUCCH index of the PUCCH resource set corresponding to the total bit range.

[0076] For example, the implementation of step S504 may further include:

[0077] The UE sets the time slot offset from PDSCH to HARQ-ACK PUCCH according to the DCI.

[0078] The UE of the HARQ-ACK feedback method provided in the present application determines the available PUCCH resources based on the configuration information of the network device, thereby avoiding the situation where the HARQ-ACK cannot be fed back due to the unavailability of the selected PUCCH resources, thereby improving the network reliability.

[0082] Step S602: The network device sends an SPS PUSCH to the UE;

[0083] Step S603: The UE determines the first SPS PUCCH resource set corresponding to the total number of comparisons according to the total number of bits, and determines whether the SPS PUCCH resources in the first SPS PUCCH resource set are available according to the identification index. If the index0 SPS PUCCH resource is available, the available PUCCH resource is determined to be the index0 SPS PUCCH resource.

[0084] The UE of the HARQ-ACK feedback method provided in the present application determines the available PUCCH resources based on the configuration information of the network device, thereby avoiding the situation where the HARQ-ACK cannot be fed back due to the unavailability of the selected PUCCH resources, thereby improving the network reliability.
