Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application claims priority to Chinese Patent Application No. 202210130233.8, filed in China on February 11, 2022, the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the field of communication technology, and specifically to a response feedback method and device, a terminal, and a readable storage medium. [Background technology]

[0003] After the base station transmits a Physical Downlink Shared Channel (PDSCH) or a Physical Downlink Control Channel (PDCCH) (e.g., a PDCCH instructing a Semi-Persistent Scheduling (SPS) PDSCH release), the terminal (User Equipment, UE) receives and completes decoding, and then feeds back the PDSCH / PDCCH decoding result to the base station and notifies the base station whether the PDSCH / SPS PDSCH release PDCCH has been successfully decoded. The base station makes the next scheduling decision based on the feedback, and this process is called Hybrid Automatic Repeat Request (HARQ). The HARQ feedback scheme includes HARQ-Acknowledge (ACK) / Not Acknowledge (NACK) and HARQ NACK only, in the HARQ-ACK / NACK feedback mode, if the UE successfully decodes the PDSCH / PDCCH, it will feed back an ACK, otherwise it will feed back a NACK, in the HARQ NACK only feedback mode, if the UE fails to successfully decode the PDSCH / PDCCH, it will feed back a NACK, and will not feed back any information at other times.

[0004] For the NACK only feedback mode, the PUCCH may be group common, i.e., different UEs can feed back NACK information of the same PDSCH on the same PUCCH. In NR, the time unit (slot or subslot) for feeding back HARQ is determined by k1 (feedback timing indication from PDSCH to HARQ) indicated in the downlink control information (DCI) of downlink scheduling, where k1 represents the number of time units from the time unit where the PDSCH end position is located to the HARQ feedback, i.e., when the UE receives the PDSCH in time unit n, the UE feeds back its corresponding HARQ information in time unit n+k1.

[0005] For the NACK only feedback mode, the PUCCH that feeds back the NACK only is common to the group, so when the UE feeds back the NACK on one PUCCH, the base station regards the PDSCH corresponding to this NACK as a decoding error, and retransmits the corresponding PDSCH. When multiple PDSCHs are scheduled in the same time unit (slot / subslot), it is necessary to solve how the UE feeds back the NACK only for multiple PDSCHs.

The terms "system" and "network" in the embodiments of the present application are always used interchangeably, and the techniques described may be used in the above-mentioned systems and radio technologies, or in other systems and radio technologies. Although the following description describes a New Radio (NR) system for illustrative purposes and uses NR terminology in most of the description below, these techniques may be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

[0019] 1 shows a block diagram of a wireless communication system to which an embodiment of the present application can be applied. The wireless communication system includes a terminal 11 and a network side device 12. Here, the terminal 11 may be a mobile phone, a tablet personal computer, a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, a vehicle user equipment (VUE), a pedestrian user equipment (PUE), a smart home (home equipment having a wireless communication function, such as a refrigerator, a television, a washing machine, or furniture), a game machine, a personal computer, a mobile phone, a mobile terminal (Mobile Internet Device), a mobile user equipment (MID), a mobile terminal (Mobile User Equipment ... The network side device 12 may be a terminal side device such as a mobile computer (PC), a deposit and withdrawal machine or a self-service machine, and the wearable device includes a smart watch, a smart band, a smart earphone, a smart glasses, a smart accessory (such as a smart bracelet, a smart ring, a smart necklace, a smart anklet, a smart wristband, a smart clothing, etc.). It should be noted that the embodiment of the present application does not limit the specific type of the terminal 11. The network side device 12 may include an access network device or a core network device, where the access network device may be referred to as a radio access network device, a radio access network (Radio Access Network, RAN), a radio access network function, or a radio access network unit.The access network equipment may include a base station, a Wireless Local Area Network (WLAN) access point, or a WiFi node, and the base station may be called a Node B, an evolved Node B (eNB), an access point, a Base Transceiver Station (BTS), a radio base station, a radio transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a home B node, a home evolved B node, a Transmitting Receiving Point (TRP), or any other suitable term in the art. As long as the same technical effect is achieved, the base station is not limited to a specific technical term, and it should be explained that in the embodiments of this application, only a base station in an NR system is taken as an example, but the specific type of the base station is not limited.

[0020] Currently, NR technology has not supported broadcast / multicast features for a long time, but there are many important usage scenarios in which broadcast / multicast features can provide substantial improvements, especially in terms of system efficiency and user experience, such as public safety and mission critical, V2X applications, transparent IPv4 / IPv6 multicast delivery, interactive network television (IPTV), software delivery over wireless, group communications and IoT applications, etc. Therefore, NR introduces broadcast / multicast features.

[0021] In NR multicast transmission, Point-To-Multipoint (PTM) multicast service transmission is supported. PTM is a multicast transmission method in which a Physical Downlink Control Channel (PDCCH) scrambled by a Group Radio Network Temporary Identifier (G-RNTI) schedules a Physical Downlink Shared Channel (PDSCH) scrambled by the G-RNTI to perform service scheduling and transmission. The PDCCH or PDSCH scrambled by the G-RNTI may be received simultaneously by one group of terminals.

[0022] After the base station transmits a PDSCH or PDCCH (such as a PDCCH indicating a semi-static scheduling (SPS) PDSCH release), the UE receives and completes decoding, then feeds back the PDSCH / PDCCH decoding result to the base station and informs the base station whether the PDSCH / SPS PDSCH release PDCCH is successfully decoded. The base station makes the next scheduling decision based on the feedback, and this process is called Hybrid Automatic Repeat Request (HARQ). The HARQ feedback method includes HARQ-acknowledgement (ACK) / negative acknowledgement (NACK) and HARQ NACK only, and in the HARQ-ACK / NACK feedback mode, if the UE successfully decodes the PDSCH / PDCCH, it feeds back an ACK, otherwise it feeds back a NACK. In the HARQ NACK only feedback mode, the UE feeds back a NACK when the UE does not successfully decode the PDSCH / PDCCH, and does not feed back information at other times. The Physical Uplink Control Channel (PUCCH) is the main channel carrying HARQ information (HARQ information may also be carried on the Physical Uplink Shared Channel (PUSCH), and if the time domain resources of the PUCCH carrying HARQ-ACK / NACK and the PUSCH overlap, the HARQ-ACK / NACK are multiplexed and transmitted on the PUSCH). For the ACK / NACK mode feedback, the PUCCH is UE-specific, i.e., the PUCCHs of different UEs are different. For the NACK only feedback mode, the PUCCH may be group-common, i.e., different UEs can feedback NACK information of the same PDSCH on the same PUCCH.In NR, it is determined by k1 (feedback timing indication from PDSCH to HARQ) indicated in the downlink control information (DCI) of downlink scheduling, and determines the time unit (slot or subslot) for feeding back HARQ, where k1 represents the number of time units from the time unit where the PDSCH end position is located to the HARQ feedback, i.e., when the UE receives the PDSCH in time unit n, the UE feeds back the corresponding HARQ information in time unit n+k1. Here, for different PDSCHs, k1 may take different values, and the base station first configures a k1 set through radio resource control (RRC) signaling, and then indicates a specific value through DCI. If there is no k1 domain in DCI, it is determined by higher layer parameters.

[0023] For the NACK only feedback mode, only PUCCH format 0 / 1 is currently supported. Since the PUCCH that feeds back NACK only is common to the group, when a UE feeds back a NACK on one PUCCH, the base station regards this NACK as a decoding error of the PDSCH corresponding to the PDSCH, and performs a corresponding PDSCH retransmission. When multiple PDSCHs are scheduled in the same time unit (slot / subslot), it is necessary to solve how the UE feeds back NACK only for multiple PDSCHs.

[0024] The following describes in detail the response feedback method according to the embodiments of the present application through several embodiments and its application scenarios in conjunction with the drawings.

[0025] An embodiment of the present application provides a response feedback method, as shown in FIG. When the terminal is scheduled to feedback hybrid automatic repeat request (HARQ) information of N downlink transmissions in one time unit, the terminal includes: determining 101 a feedback manner and / or feedback resource for feedbacking a response according to the first information, where N is a positive integer; Wherein, the first information includes at least one of a number N of downlink transmissions, a number of group wireless network temporary identifiers, and whether a network side device configures a first parameter; The first parameter is used to indicate a feedback manner and / or a feedback resource selection manner for feeding back a response; The feedback manner includes a first feedback manner and a second feedback manner, in which the first feedback manner is that the terminal feeds back an acknowledgement ACK when the terminal successfully decodes the physical downlink shared channel and / or the physical downlink control channel, and the terminal feeds back a negative acknowledgement NACK (i.e., a HARQ-ACK / NACK feedback mode) when the terminal does not successfully decode the physical downlink shared channel and / or the physical downlink control channel; The second feedback manner is that the terminal only feeds back a negative acknowledgement (ie, NACK only mode) when the terminal fails to decode the physical downlink shared channel and / or the physical downlink control channel.

[0026] In an embodiment of the present application, when a terminal is scheduled to feed back HARQ information for multiple downlink transmissions in one time unit, the terminal determines a feedback scheme and / or feedback resource for feeding back a response based on the first information, and thus, when multiple downlink transmissions are scheduled in the same time unit, the feedback scheme and feedback resource for the terminal to feed back a response can be clarified, thereby improving the effectiveness of the communication system.

[0027] Here, the network side device may configure the first parameter, or may not configure the first parameter. When the network side device does not configure the first parameter, that is, when the network side device does not configure the first parameter, the first parameter adopts a default value.

[0028] The first parameter is used to configure a feedback scheme in a scenario in which "the terminal is scheduled to feedback HARQ information of N downlink transmissions in one time unit", and the value may be mode 1 or mode 2. For example, when the value of the first parameter is mode 1, it instructs to adopt a HARQ-ACK / NACK feedback mode, and when the value of the first parameter is mode 2, it instructs to adopt a NACK only feedback mode. Alternatively, the first parameter is used to configure a feedback scheme in a scenario in which "the terminal is scheduled to feedback HARQ information of N downlink transmissions in one time unit", and the value of the first parameter may be mode 1 or mode 2. For example, when the value of the first parameter is mode 1, it instructs to adopt a HARQ-ACK / NACK feedback mode, and when the value of the first parameter is mode 2, it instructs to adopt a NACK only feedback mode. The first parameter is used to configure whether to adopt the HARQ-ACK / NACK feedback mode in a scenario in which "the terminal is scheduled to feedback HARQ information for N downlink transmissions in one time unit", and the value may be enable or disable, or the default value of the first parameter is disable. For example, when the value of the first parameter is enable, it instructs to adopt the HARQ-ACK / NACK feedback mode, and when the value of the first parameter is disable, it instructs not to adopt the HARQ-ACK / NACK feedback mode.

[0029] Here, N may be an integer greater than 1, and when N is greater than 1, the HARQ feedback mode corresponding to each of the N downlink transmissions is a NACK only mode, i.e., the feedback mode of each downlink transmission determined based on the higher layer parameter configuration is a NACK only mode, for example, per G-RNTI and / or Group-Configured Scheduling-Radio Network Temporary Identity (G-CS-RNTI) configures the feedback mode of a PDSCH, and the UE determines that the HARQ feedback mode of the downlink transmission is the NACK only mode based on the G-RNTI and / or G-CS-RNTI corresponding to the downlink transmission.

[0030] Here, the downlink transmission includes a Physical Downlink Shared Channel (PDSCH) and / or a Transport Block (TB), and the time unit includes a slot and a sub-slot.

[0031] In some embodiments, the network side device configures a first parameter, the first parameter being: The terminal, when one group radio network temporary identifier is configured or activated, feeds back HARQ information of a plurality of downlink transmissions by adopting the second feedback manner in one time unit; The terminal, when a plurality of group radio network temporary identifiers are configured or activated, employs the first feedback manner in one time unit to feed back HARQ information of at most one downlink transmission; feeding back HARQ information of a plurality of downlink transmissions by adopting the first feedback scheme in one time unit; and feeding back HARQ information of a plurality of downlink transmissions by employing the second feedback scheme in one time unit.

[0032] In this embodiment, the terminal adopts the second feedback scheme to feed back HARQ information for multiple downlink transmissions, or adopts the first feedback scheme to feed back HARQ information for multiple downlink transmissions, without considering the number of configured or activated group radio network temporary identifiers, or decides whether to adopt the first feedback scheme or the second feedback scheme based on whether a first parameter of the base station is configured.

[0033] When the UE configures or activates one G-RNTI (or configures a G-RNTI whose feedback mode corresponds to NACK only), the base station may schedule multiple TBs and / or PDSCHs to be fed back NACK only in one time unit, and when the number of TBs and / or PDSCHs is equal to or less than Y, up to X orthogonal PUCCH resources are defined to correspond to TBs and / or PDSCHs for which up to Y NACK only feedback is scheduled, respectively, where X and Y are integers greater than 1. When the number of TBs and / or PDSCHs is greater than Y, up to X orthogonal PUCCH resources are defined to correspond to TBs and / or PDSCHs for which up to Y NACK only feedback is scheduled, respectively, where X and Y are integers greater than 1. The only feedback mode is converted to an ACK / NACK mode, and the UE feedbacks according to the ACK / NACK mode, and the corresponding PUCCH is determined in the PUCCH configuration (PUCCH-config) / PUCCH configuration list (PUCCH-configList) corresponding to the ACK / NACK (or determined in the PUCCH configuration corresponding to unicast PDSCH feedback). Specifically, the UE determines a resource set in which the PUCCH is located based on the number of ACK / NACK bits, and determines a feedback resource for feeding back the ACK or NACK based on a PUCCH resource indicator (PUCCH resource indicator, PRI) and / or a control channel element (Control-Channel Element, CCE) index indication in the last downlink control information (last DCI) within the set.

[0034] Alternatively, Y may be less than X, but of course Y may be equal to or greater than X. For example, X=15, Y=4, or X=32, Y=2, etc.

[0035] Optionally, the values ​​of X, Y may be specified by a protocol or predefined or configured by a higher layer parameter. In some embodiments, the first information includes a number of downlink transmissions and a number of group radio network temporary identifiers, and determining a feedback scheme and / or feedback resource for the terminal to feedback a response based on the first information includes: When the terminal configures or activates a group radio network temporary identifier, if the number of downlink transmissions is equal to or less than Y, determine that a feedback scheme for feeding back a response is the second feedback scheme, and feed back HARQ information of up to Y downlink transmissions using up to X orthogonal PUCCH resources, where X and Y are positive integers greater than 1, if the number of downlink transmissions is greater than Y, determine that a feedback scheme for feeding back a response is the first feedback scheme, and determine a feedback resource for feeding back an ACK or NACK according to a second parameter configured by a network side device or a specific physical uplink control channel PUCCH configuration information or configuration information list of the terminal; When the terminal configures or activates multiple group wireless network temporary identifiers, it determines that the feedback scheme for feeding back a response is the first feedback scheme, and determines a feedback resource for feeding back an ACK or NACK based on a second parameter configured by the network side device or specific PUCCH configuration information or configuration information list of the terminal.

[0036] Alternatively, Y may be less than X, but of course Y may be equal to or greater than X. For example, X=15, Y=4, or X=32, Y=2, etc.

[0037] Alternatively, the values ​​of X, Y may be specified by the protocol or may be predefined or configured by higher layer parameters. When a G-RNTI is configured or activated (or a G-RNTI / G-CS-RNTI is configured, or a G-RNTI with a corresponding feedback mode of NACK only is configured, or a G-RNTI / G-CS-RNTI with a corresponding feedback mode of NACK only is configured), if the number of TBs and / or PDSCHs is less than or equal to Y, the UE defines up to X orthogonal PUCCH resources to correspond to TBs and / or PDSCHs for scheduling up to Y NACK only feedbacks, respectively; if the number of TBs and / or PDSCHs is greater than Y, the NACK only feedback mode is converted to an ACK / NACK mode, and the UE feedbacks according to the ACK / NACK mode, and the corresponding PUCCH is determined in the PUCCH-config / PUCCH-configList corresponding to the ACK / NACK; and the specific UE determines a resource set in which the PUCCH is located according to the number of bits of the ACK / NACK, and determines the PRI and / or CCE in the closest downlink control information (last DCI) in the set. The feedback resource for feeding back an ACK or NACK is determined based on the index indication.

[0038] Alternatively, the network side equipment can ensure that more than Y TBs and / or PDSCHs do not occur, and thus does not need to support scenarios where the number of TBs and / or PDSCHs is greater than Y.

[0039] Otherwise, if multiple G-RNTIs are configured or activated (or one G-RNTI / G-CS-RNTI is configured, or multiple G-RNTIs with corresponding feedback mode of NACK only are configured, or one G-RNTI / G-CS-RNTI with corresponding feedback mode of NACK only is configured), the UE converts the NACK only feedback mode to ACK / NACK mode, and the UE feedbacks according to the ACK / NACK mode, and the corresponding PUCCH is determined in the PUCCH-config / PUCCH-configList corresponding to the ACK / NACK, and a specific UE determines a resource set in which the PUCCH is located based on the number of bits of the ACK / NACK, and within the set, determines a feedback resource to feed back the ACK or NACK based on the PRI and / or CCE index indication in the last DCI.

[0040] Here, the group radio network temporary identifier includes a G-RNTI, or includes a G-RNTI and a G-CS-RNTI.

[0041] In some embodiments, the first information includes a number of downlink transmissions and the first parameter configured by a network side device, and determining a feedback scheme and / or feedback resource for the terminal to feed back a response based on the first information includes: When the network side device configures the first parameter, if the number of downlink transmissions is less than or equal to Y, determine that a feedback scheme for feeding back a response is the second feedback scheme, and feed back HARQ information of up to Y downlink transmissions using up to X orthogonal PUCCH resources, where X and Y are positive integers greater than 1, if the number of downlink transmissions is greater than Y, determine that the feedback scheme for feeding back a response is the first feedback scheme, and determine a feedback resource for feeding back an ACK or NACK according to the second parameter configured by the network side device or specific PUCCH configuration information or configuration information list of a terminal; If the first parameter is not configured in the network side equipment, determining that a feedback scheme for feeding back a response is the first feedback scheme, and determining a feedback resource for feeding back an ACK or NACK based on a second parameter configured by the network side equipment or specific PUCCH configuration information or a configuration information list of the terminal.

[0042] Alternatively, Y may be less than X, but of course Y may be equal to or greater than X. For example, X=15, Y=4, or X=32, Y=2, etc.

[0043] Alternatively, the values ​​of X and Y may be stipulated by a protocol, or predefined, or configured by a higher layer parameter. When the network side device configures a first parameter (the first parameter is configured by the higher layer parameter), if the number of TBs and / or PDSCHs is less than or equal to Y, it defines that up to X orthogonal PUCCH resources correspond to TBs and / or PDSCHs that respectively schedule up to Y NACK-only feedbacks; or if the number of TBs and / or PDSCHs is greater than Y, the NACK-only feedback mode is converted to an ACK / NACK mode, and the UE feedbacks according to the ACK / NACK mode, and the corresponding PUCCH is determined in the PUCCH-config / PUCCH-configList corresponding to the ACK / NACK; and the specific UE determines a resource set in which the PUCCH is located according to the number of bits of the ACK / NACK, and determines a feedback resource within the set to feed back the ACK or NACK according to the PRI and / or CCE index indication in the last DCI.

[0044] Alternatively, the network side equipment can ensure that more than Y TBs and / or PDSCHs do not occur, and thus does not need to support scenarios where the number of TBs and / or PDSCHs is greater than Y.

[0045] If the network side equipment does not configure the first parameter (the upper layer parameter does not configure the first parameter), the NACK only feedback mode is converted to ACK / NACK mode, and the UE feedbacks according to the ACK / NACK mode, and the corresponding PUCCH is determined in the PUCCH-config / PUCCH-configList corresponding to the ACK / NACK. A specific UE determines a resource set in which the PUCCH is located based on the number of ACK / NACK bits, and determines a feedback resource within the set to feed back ACK or NACK based on the PRI and / or CCE index indication in the last DCI.

[0046] In another embodiment, it may further be as follows.

[0047] When the network side device does not configure the first parameter (the upper layer parameter does not configure the first parameter), when the number of TBs and / or PDSCHs is less than or equal to Y, up to X orthogonal PUCCH resources are defined to correspond to TBs and / or PDSCHs for scheduling up to Y NACK only feedbacks, respectively; or when the number of TBs and / or PDSCHs is greater than Y, the NACK only feedback mode is converted to an ACK / NACK mode, and the UE feedbacks according to the ACK / NACK mode, and the corresponding PUCCH is determined in the PUCCH-config / PUCCH-configList corresponding to the ACK / NACK. A specific UE determines a resource set in which the PUCCH is located based on the number of ACK / NACK bits, and determines a feedback resource within the set to feed back ACK or NACK based on the PRI and / or CCE index indication in the last DCI.

[0048] Alternatively, the network side equipment can ensure that more than Y TBs and / or PDSCHs do not occur, and thus does not need to support scenarios where the number of TBs and / or PDSCHs is greater than Y.

[0049] When the network side device configures a first parameter (the first parameter is configured by the higher layer parameter), the NACK only feedback mode is converted to an ACK / NACK mode, and the UE feedbacks according to the ACK / NACK mode, and the corresponding PUCCH is determined in the PUCCH-config / PUCCH-configList corresponding to the ACK / NACK, and the specific UE determines a resource set in which the PUCCH is located according to the number of bits of the ACK / NACK, and determines a feedback resource for feeding back the ACK or NACK within the set according to the PRI and / or CCE index indication in the last DCI. In some embodiments, the first information includes the number of downlink transmissions and the number of group radio network temporary identifiers; When multiple downlink transmissions correspond to multiple group wireless network temporary identifiers, assign different numbers to at least one downlink transmission corresponding to the same group wireless network temporary identifier, and at least one downlink transmission with the same number constitutes one downlink transmission group, and the downlink transmissions of the same group correspond to one feedback response, and feed back a NACK when decoding of at least one downlink transmission in one group of downlink transmissions fails; If the number of the downlink transmission groups is equal to or less than Y, determine that a feedback scheme for feeding back a response is the second feedback scheme, and feed back HARQ information of up to Y groups of downlink transmissions using up to X orthogonal PUCCH resources, where X and Y are positive integers greater than 1; If the number of downlink transmission groups is greater than Y, determine that the feedback scheme for feeding back the response is the first feedback scheme, and determine the feedback resource for feeding back the ACK or NACK based on the second parameter configured by the network side device or the specific PUCCH configuration information or configuration information list of the terminal.

[0050] Alternatively, Y may be less than X, but of course Y may be equal to or greater than X. For example, X=15, Y=4, or X=32, Y=2, etc.

[0051] Alternatively, the values ​​of X, Y may be specified by a protocol or predefined or configured by higher layer parameters, where the group radio network temporary identifier includes the G-RNTI, or includes the G-RNTI and the G-CS-RNTI.

[0052] If downlink transmissions are numbered starting from 0 and the downlink transmission numbers are 0, 1, 2, . . . , n, the number of downlink transmission groups is n+1, ie the maximum number+1.

[0053] When multiple TBs and / or PDSCHs correspond to multiple G-RNTIs, the multiple TBs and / or PDSCHs of the same G-RNTI are numbered, for example 0, 1, 2, 3, 4, ..., and the NACKs only of the TBs and / or PDSCHs corresponding to different G-RNTIs with the same number are bound or compressed into one NACK only, for example, a NACK is fed back only if all of the multiple TBs and / or PDSCHs fail to be decoded, or a NACK is fed back if one of them fails to be decoded. If the number of TBs and / or PDSCHs after binding / compression is less than or equal to Y, up to X orthogonal PUCCH resources are defined to correspond to TBs and / or PDSCHs for scheduling up to Y NACK only feedbacks, respectively; if the number of TBs and / or PDSCHs after binding / compression is greater than Y, the NACK only feedback mode is converted to an ACK / NACK mode, and the UE feedbacks according to the ACK / NACK mode, and the corresponding PUCCH is determined in the PUCCH-config / PUCCH-configList corresponding to the ACK / NACK. A specific UE determines a resource set in which the PUCCH is located based on the number of ACK / NACK bits, and determines a feedback resource within the set to feed back ACK or NACK based on the PRI and / or CCE index indication in the last DCI.

[0054] Optionally, when determining the feedback resource or feedback mode, the above binding or compression operations may not be performed.

[0055] In some embodiments, the first information comprises a number of downlink transmissions and a number of group radio network temporary identifiers; When the network side device schedules, it schedules the feedback of TB and / or PDSCH corresponding to different group radio network temporary identifiers to be fed back in different time units, and in one time unit, the terminal device only expects to be scheduled to feed back NACK only information of TB and / or PDSCH of one group radio network temporary identifier. The method of feeding back multiple TB and / or PDSCH for one group radio network temporary identifier is as follows: If the number of TBs and / or PDSCHs is less than or equal to Y, then up to X orthogonal PUCCH resources are defined to correspond to TBs and / or PDSCHs for scheduling up to Y NACK only feedbacks, respectively; if the number of TBs and / or PDSCHs is greater than Y, then the NACK only feedback mode is converted to an ACK / NACK mode, and the UE feedbacks according to the ACK / NACK mode, and the corresponding PUCCH is determined in the PUCCH-config / PUCCH-configList corresponding to the ACK / NACK. A specific UE determines a resource set in which the PUCCH is located based on the number of ACK / NACK bits, and within the set, determines a feedback resource for feeding back ACK or NACK based on the PRI and / or CCE index indication in the last DCI.

[0056] Alternatively, the network side equipment can ensure that more than Y TBs and / or PDSCHs do not occur, and thus does not need to support scenarios where the number of TBs and / or PDSCHs is greater than Y.

[0057] Here, the group radio network temporary identifier includes a G-RNTI, or includes a G-RNTI and a G-CS-RNTI.

[0058] In some embodiments, the first information comprises a number of downlink transmissions and a number of group radio network temporary identifiers; When a group radio network temporary identifier is configured or activated, the terminal device defines up to X orthogonal PUCCH resources to correspond to TBs and / or PDSCHs that respectively schedule up to Y NACK only feedbacks if the number of TBs and / or PDSCHs is less than or equal to Y, or converts the NACK only feedback mode to an ACK / NACK mode if the number of TBs and / or PDSCHs is greater than Y, and the UE feedbacks according to the ACK / NACK mode, and the corresponding PUCCH is determined in the PUCCH-config / PUCCH-configList corresponding to the ACK / NACK, and a specific UE determines a resource set in which the PUCCH is located based on the number of ACK / NACK bits, and determines a feedback resource within the set to feed back an ACK or NACK based on the PRI and / or CCE index indication in the last DCI.

[0059] Alternatively, the network side equipment can ensure that more than Y TBs and / or PDSCHs do not occur, and thus does not need to support scenarios where the number of TBs and / or PDSCHs is greater than Y.

[0060] When a group radio network temporary identifier is configured or activated, the terminal device expects that the base station will schedule downlink TBs and / or PDSCHs to schedule different TBs and / or PDSCHs in different time units, i.e., the terminal device will not expect to be scheduled to feedback multiple TBs and / or PDSCHs in one time unit.

[0061] Here, the group radio network temporary identifier includes a G-RNTI, or includes a G-RNTI and a G-CS-RNTI.

[0062] In one specific example, as shown in Figure 3, assume that PDSCH1 and PDSCH2 correspond to G-RNTI1, PDSCH3 corresponds to G-RNTI2, and all three PDSCHs are scheduled to feed back HARQ information in slot n, and the corresponding feedback mode is NACK only mode. PDSCH1 and PDSCH2 are assigned numbers 0 and 1, respectively, PDSCH3 is assigned number 0, PDSCH2 is divided into one group, and PDSCH1 and PDSCH3 are divided into the same group to perform binding operation, and feedback NACK when either PDSCH1 or PDSCH3 fails to decode, or feedback NACK only when both fail to decode. The number of packets is 2, and the corresponding two NACK only need to be fed back, namely PDSCH1 / 3 and PDSCH2.

[0063] If the value of Y is 2 (or greater than 2), since the number of packets is equal to 2, determine that the feedback scheme for feedbacking the response is the second feedback scheme, and use up to X orthogonal PUCCH resources to feed back HARQ information of up to Y groups of downlink transmission, where X and Y are positive integers greater than 1.

[0064] In some embodiments, the first information includes a number N of downlink transmissions, N being greater than 1, and determining a feedback scheme and / or feedback resource for the terminal to feed back a response based on the first information includes: determining that a feedback scheme for feeding back a response is the first feedback scheme; The method includes determining a feedback resource for feeding back an ACK or NACK based on a second parameter configured by a network side device or specific PUCCH configuration information or a configuration information list of the terminal.

[0065] That is, when the number of downlink transmissions is greater than 1, the NACK only feedback mode is converted to ACK / NACK mode, and the UE feedbacks according to the ACK / NACK mode, and the corresponding PUCCH is determined in the PUCCH-config / PUCCH-configList corresponding to the ACK / NACK. A specific UE determines a resource set in which the PUCCH is located based on the number of ACK / NACK bits, and determines a feedback resource within the set to feed back ACK or NACK based on the PRI and / or CCE index indication in the last DCI.

[0066] In some embodiments, the first information includes a number of downlink transmissions, and determining a feedback scheme and / or feedback resource for the terminal to feed back a response based on the first information includes: If the number of downlink transmissions is less than or equal to Y, determine that a feedback scheme for feeding back a response is the second feedback scheme, and feed back HARQ information of up to Y downlink transmissions using up to X orthogonal PUCCH resources, where X and Y are positive integers greater than 1; If the number of downlink transmissions is greater than Y, determining that the feedback scheme for feeding back a response is the first feedback scheme, and determining a feedback resource for feeding back an ACK or NACK based on second parameters configured by a network side device or specific PUCCH configuration information or configuration information list of the terminal.

[0067] Alternatively, Y may be less than X, but of course Y may be equal to or greater than X. For example, X=15, Y=4, or X=32, Y=2, etc.

[0068] Alternatively, the values ​​of X, Y may be specified by the protocol or may be predefined or configured by higher layer parameters.

[0069] If the number of TBs and / or PDSCHs is less than or equal to Y, then up to X orthogonal PUCCH resources are defined to correspond to TBs and / or PDSCHs that respectively schedule up to Y NACK only feedbacks; if the number of TBs and / or PDSCHs is greater than Y, then the NACK only feedback mode is converted to an ACK / NACK mode, and the UE feedbacks according to the ACK / NACK mode, and the corresponding PUCCH is determined in the PUCCH-config / PUCCH-configList corresponding to the ACK / NACK. A specific UE determines a resource set in which the PUCCH is located based on the number of ACK / NACK bits, and within the set, determines a feedback resource for feeding back ACK or NACK based on the PRI and / or CCE index indication in the last DCI.

[0070] In one specific example, if the number of TBs and / or PDSCHs is less than or equal to Y, up to X orthogonal PUCCH resources are defined to correspond to up to Y TBs and / or PDSCHs for scheduling NACK only feedback, respectively.

[0071] For example, X=15, Y=4, ie, up to 15 orthogonal PUCCH resources are defined to correspond to up to 4 TBs and / or PDSCHs each scheduling NACK only feedback.

[0072] For a maximum of four TBs, the TB combination has four cases, such as one TB, two TBs, three TBs, or four TBs. Suppose that the corresponding TB has a scheduling and needs to feed back a NACK with 1, and 0 indicates that there is no scheduling or there is no need to feed back a NACK, i.e. There are four cases for one TB, for example (1,0,0,0), (0,1,0,0), (0,0,1,0), and (0,0,0,1), where (1,0,0,0) indicates that the first TB has scheduling and a NACK needs to be fed back, (0,1,0,0) indicates that the second TB has scheduling and a NACK needs to be fed back, (0,0,1,0) indicates that the third TB has scheduling and a NACK needs to be fed back, and (0,0,0,1) indicates that the fourth TB has scheduling and a NACK needs to be fed back.

[0073] There are six cases for the two TBs, e.g. (1,1,0,0), (1,0,1,0), (1,0,0,1), (0,1,1,0), (0,1,0,1), (0,0,1,1), where (1,1,0,0) indicates that the first and second TBs have scheduling and a NACK needs to be fed back, (1,0,1,0) indicates that the first and third TBs have scheduling and a NACK needs to be fed back, and so on.

[0074] There are four cases for the three TBs, for example (1,1,1,0), (1,1,0,1), (1,0,1,1), and (0,1,1,1), where (1,1,1,0) indicates that the first, second and third TBs have scheduling and NACKs need to be fed back, (1,1,0,1) indicates that the first, second and fourth TBs have scheduling and NACKs need to be fed back, (1,0,1,1) indicates that the first, third and fourth TBs have scheduling and NACKs need to be fed back, and (0,1,1,1) indicates that the second, third and fourth TBs have scheduling and NACKs need to be fed back.

[0075] There is only one case for the four TBs, for example (1,1,1,1), which indicates that the 1st to 4th TBs have scheduling and need to feed back NACK.

[0076] Fifteen orthogonal PUCCH resources (each PUCCH resource is of format 0 / 1) may be defined, corresponding to the above 15 types of combinations respectively. For example, when the UE needs to feed back NACK for only the first TB, i.e. (1,0,0,0), the first PUCCH resource is used; when the UE needs to feed back NACK for four TBs, i.e. (1,1,1,1), the 15th PUCCH resource is used; there is one-to-one mapping between the above combinations and PUCCH resources, and the mapping relationship may be pre-defined or configured in higher layer parameters.

In the embodiment of the present application, the response feedback device according to the embodiment of the present application will be described by taking the response feedback method performed by the response feedback device as an example.

[0078] The embodiment of the present application provides a response feedback device, which is applied to a terminal 200, as shown in FIG. A processing module 201 for determining a feedback scheme and / or feedback resource for feedbacking a response according to the first information when the terminal is scheduled to feedback hybrid automatic repeat request (HARQ) information of N downlink transmissions in one time unit, where N is a positive integer; Wherein, the first information includes at least one of a number N of downlink transmissions, a number of group wireless network temporary identifiers, and whether a network side device configures a first parameter; The first parameter is used to indicate a feedback manner and / or a feedback resource selection manner for feeding back a response; The feedback manner includes a first feedback manner and a second feedback manner, in which the first feedback manner is that the terminal feeds back an acknowledgement (ACK) when the terminal successfully decodes the physical downlink shared channel and / or the physical downlink control channel, and the terminal feeds back a negative acknowledgement (NACK) when the terminal does not successfully decode the physical downlink shared channel and / or the physical downlink control channel; The second feedback manner is that the terminal only feeds back a negative acknowledgement if the terminal fails to decode the physical downlink shared channel and / or the physical downlink control channel.

[0102] In some embodiments, the processor 710 is configured to determine a feedback scheme and / or feedback resource for feeding back a response based on the first information when the terminal is scheduled to feed back hybrid automatic repeat request (HARQ) information for N downlink transmissions in one time unit, where N is a positive integer; Wherein, the first information includes at least one of a number N of downlink transmissions, a number of group wireless network temporary identifiers, and whether a network side device configures a first parameter; The first parameter is used to indicate a feedback manner and / or a feedback resource selection manner for feeding back a response; The feedback manner includes a first feedback manner and a second feedback manner, in which the first feedback manner is that the terminal feeds back an acknowledgement (ACK) when the terminal successfully decodes the physical downlink shared channel and / or the physical downlink control channel, and the terminal feeds back a negative acknowledgement (NACK) when the terminal does not successfully decode the physical downlink shared channel and / or the physical downlink control channel; The second feedback manner is that the terminal only feeds back a negative acknowledgement if the terminal fails to decode the physical downlink shared channel and / or the physical downlink control channel.
