Description

[Technical field]

[0001] The present disclosure relates to the field of communication technology, and in particular to a feedback method, a feedback device, and a storage medium. [Background technology]

[0002] In New Radio (NR) technology, for example, when the communication frequency band is frequency range 2, high frequency channels attenuate quickly, so beam-based transmission and reception must be used to ensure coverage range.

[0003] In the related art, beams such as a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), and each uplink / downlink reference signal are independently indicated. In addition, the PDCCH and the PUCCH activate the beams using a medium access control (MAC) control unit (control element, CE). The PDSCH and the PUSCH indicate their respective beams by downlink control information (DCI) signaling. Currently, in order to reduce signaling overhead, a common beam (common beam, unified beam, or unified TCI state) is used for indication. The common beam may be used to indicate the uplink and downlink channels and / or reference signals of the terminal.

[0004] In the related technology, a common beam is specified using DCI signaling for scheduling a PDSCH, and whether or not the common beam information is correctly received must be determined by a PDSCH hybrid automatic repeat request (HARQ) positive acknowledgement (ACK) feedback. However, if the common beam information is correctly received or not determined based on the PDSCH HARQ ACK feedback, it may be erroneously determined whether or not the common beam information is correctly received. For example, if the PDSCH HARQ ACK feedback is a negative acknowledgement (NACK), if the decoding of the PDCCH DCI signaling is successful, that is, if the common beam information is successfully received, it is erroneously determined that the common beam information is not correctly received.

[0075] Reference will now be made in detail to exemplary embodiments illustrated in the drawings. Where the following description refers to the drawings, the same numerals in different drawings represent the same or similar elements unless otherwise stated. The embodiments described in the following exemplary embodiments are not representative of all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0076] The feedback method according to the embodiment of the present disclosure can be used in the wireless communication system shown in Figure 1. As shown in Figure 1, the wireless communication system includes a terminal and a network device. The terminal is connected to the network device through a radio resource, and transmits and receives data.

[0077] It can be understood that the wireless communication system illustrated in Fig. 1 is merely a schematic illustration, and the wireless communication system may further include other network devices not illustrated in Fig. 1, such as a core network device, a wireless relay device, a wireless backhaul device, etc. The embodiments of the present disclosure do not limit the number of network devices and the number of terminals included in the wireless communication system.

[0078] For further understanding, the wireless communication system of the embodiment of the present disclosure is a network that provides wireless communication functions. The wireless communication system can use different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), and carrier sense multiple access with collision avoidance (Carrier Sense Multiple Access with Collision Avoidance). Based on factors such as capacity, speed, and delay of different networks, the networks can be divided into 2G (English: generation) networks, 3G networks, 4G networks, or future evolution networks, such as 5G networks, which may be referred to as New Radio (NR) networks. For ease of description, the wireless communication network may be abbreviated to network in this disclosure.

[0079] Furthermore, the network device according to the present disclosure may be referred to as a radio access network device. The radio access network device may be a base station, an evolved base station (eNB), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a radio relay node, a radio backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc., or may be a gNB in ​​an NR system, or may be a component or part of a device constituting a base station. In the case of a vehicle Internet (V2X) communication system, the network device may also be an in-vehicle device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and the specific device form used for the network device.

[0080] Furthermore, the terminal according to the present disclosure may be called a terminal device, a user device (User Equipment, UE), a mobile station (MS), a mobile terminal (MT), etc., and is a device that provides voice and / or data connectivity to a user. For example, the terminal may be a handheld device with a wireless connection function, an in-vehicle device, etc. Currently, some examples of terminals include a mobile phone, a pocket personal computer (PPC), a palmtop computer, a personal digital assistant (PDA), a notebook computer, a tablet computer, a wearable device, or an in-vehicle device. In addition, in the case of a vehicle Internet (V2X) communication system, the terminal device may also be an in-vehicle device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and the specific device form used for the terminal.

[0081] In the present disclosure, data transmission is performed between a network device and a terminal based on a beam. In the process of performing data transmission based on a beam, a common beam is used to indicate a channel and / or a reference signal in order to reduce signaling overhead. In the related art, the common beam may be an independent indication of uplink transmission or downlink transmission, or a joint indication of uplink transmission and downlink transmission. For example, when a network device indicates a common beam for a downlink, the common beam may be used to indicate a PDSCH and all or some of the PDCCHs of the terminal (e.g., a terminal-dedicated PDCCH (UE dedicated PDCCH)). When a network device indicates a common beam for an uplink, the common beam may be used to indicate a PUSCH and all or some of the PUCCHs of the terminal. When a network device indicates a common beam, the beam may be used to indicate an uplink and downlink channel and / or a reference signal of the terminal.

[0082] Which channel and / or reference signal a common beam is used to indicate is indicated by signaling or specified by a standard, and the terminal can know it.

[0083] In the related art, the DCI signaling for scheduling the PDSCH is used to indicate the common beam, and the HARQ ACK feedback of the PDSCH is multiplexed to determine whether the common beam information in the DCI is correctly received. For example, when the HARQ ACK feedback of the PDSCH is NACK, it indicates both the failure of receiving the PDSCH and the failure of receiving the common beam information, and when the HARQ ACK feedback of the PDSCH is ACK, it indicates both the success of receiving the PDSCH and the success of receiving the common beam information. However, when the HARQ ACK feedback of the PDSCH is actually NACK, there is also a situation where the decoding of the DCI signaling of the PDCCH is successful, that is, the success of receiving the common beam information, but the failure of receiving the PDSCH. Therefore, in this case, when the terminal feeds back the NACK, it cannot accurately notify the network device whether the common beam information is successfully received. That is, when the HARQ ACK feedback of the PDSCH is multiplexed, the network device cannot accurately determine whether the common beam information indicated by the DCI is correctly received.

[0084] The embodiment of the present disclosure provides a feedback method mainly used in a scenario of HARQ ACK feedback when DCI signaling indicates common beam information. A terminal receives DCI indicating common beam information, determines whether the DCI indicating common beam information is correctly received, and sends a feedback result to a network device for indicating whether the DCI is correctly received, thereby reducing HARQ ACK signaling overhead and ensuring that the network device accurately knows whether the common beam information is correctly received by the terminal.

[0085] In the embodiment of the present disclosure, the DCI is used to indicate one or more common beams. The common beam may be called a common transmission configuration indication state (common TCI state) or a unified TCI state. When the unified TCI state is used for both the uplink and the downlink, it is also called a joint TCI state. When the unified TCI state is used only for the downlink or the uplink, it is also called a separate UL TCI state or a separate DL TCI state.

[0086] As can be understood, the common TCI state / unified TCI state according to the embodiments of the present disclosure may be understood as corresponding to the common beam. In the embodiments of the present disclosure, the common beam and the common TCI state / unified TCI state may be used interchangeably, and those skilled in the art should understand the consistency of the meaning.

[0087] FIG. 2 is a flowchart of a feedback method shown in an exemplary embodiment. As shown in FIG. 2, the feedback method is used in a terminal and includes the following steps:

[0088] In step S11, DCI for indicating common beam information is received.

[0089] In step S12, it is determined whether the DCI indicating the common beam information is correctly received, and a feedback result is sent to the network device to indicate whether the DCI is correctly received.

[0090] In the feedback method according to the embodiment of the present disclosure, a terminal receives DCI for indicating common beam information. The common beam information is used to indicate beams corresponding to all members in a common beam group. The terminal determines whether the common beam information indicated by the DCI is correctly received, and feeds back HARQ ACK / NACK information to a network device.

[0091] As can be understood, in an embodiment of the present disclosure, a member in a common beam group includes at least one channel and / or at least one reference signal resource, the channel including at least one of a PDCCH, a PDSCH, a PUSCH, a PUCCH, a Physical Random Access Channel (PRACH), and a Physical Broadcast Channel (PBCH).

[0092] Furthermore, if the member includes a PDCCH, the member may be a control resource set (CORESET) for PDCCH transmission.

[0093] The PDSCH is indicated by the CORESET that schedules this PDSCH or is identified by a semi-persistent PDSCH identifier. The PUCCH is identified by a PUCCH resource ID or is indicated by the CORESET that schedules this PUCCH. The PUSCH is indicated by the CORESET that schedules this PUSCH or is identified by a PUSCH identifier in a configured grant. The PRACH is indicated by a random access resource ID. The PBCH is indicated by a Synchronization Signal and PBCH block index (SSB index).

[0094] As can be understood, in an embodiment of the present disclosure, the reference signal resources of the members in the common beam group include at least one of a Channel State Information Reference Signal (CSI-RS), a Sounding Reference Signal (SRS), a Positioning reference signal (PRS), a Tracking reference signal (TRS), a Synchronization Signal and PBCH block (SSB), etc.

[0095] The CSI-RS includes a CSI-RS for channel state information measurement, a CSI-RS for beam measurement, or a CSI-RS for pathloss estimation. The SRS includes an SRS for channel state information measurement based on a codebook or non-codebook, an SRS for beam measurement, or an SRS for positioning measurement. The reference signal resource is indicated by a resource identifier or a resource set identifier.

[0096] In the feedback method according to the embodiment of the present disclosure, in one aspect, the DCI received by the terminal is further used for scheduling the PDSCH and / or the PUSCH, for example, the DCI is further used for time domain and / or frequency domain resources for scheduling the PDSCH.

[0097] In another aspect of the feedback method according to the embodiment of the present disclosure, the DCI received by the terminal is not used for scheduling the PDSCH and / or PUSCH, but is used only to indicate common beam information.

[0098] In the feedback method according to the embodiment of the present disclosure, the step of the terminal determining whether DCI is correctly received may be understood as determining whether common beam information is correctly received based on the DCI. In the following embodiments, the step of determining whether DCI is correctly received and the step of determining whether common beam information is correctly received may be used interchangeably, and those skilled in the art should understand the consistency of their meanings.

[0099] In the feedback method according to the embodiment of the present disclosure, the terminal can determine whether the common beam information has been correctly received based on whether the DCI has been successfully decoded.

[0103] In step S31, in response to the DCI not being successfully decoded, it is determined that the DCI has not been correctly received, indicating that the common beam information has not been correctly received.

[0104] In the feedback method according to the embodiment of the present disclosure, the step of the terminal transmitting a feedback result to the network device for indicating whether the DCI is correctly received may be understood as the terminal transmitting a feedback result to the network device for indicating whether the common beam information is correctly received. In the embodiment of the present disclosure, the terminal may transmit an acknowledgement response or a non-acknowledgement response to the DCI to the network device to indicate whether the common beam information is correctly received.

[0105] 5 is a flowchart of a feedback method shown in an exemplary embodiment, which may be implemented alone or in combination with other embodiments of the present disclosure. As shown in FIG. 5, the feedback method is used in a terminal and includes the following steps:

[0106] In step S41, an acknowledgement response or a non-acknowledgement response to the DCI is transmitted to the network device.

[0107] In one embodiment, a feedback method according to an embodiment of the present disclosure includes, in response to the DCI not being received correctly, sending a non-acknowledgement response to the DCI to the network device to indicate that the common beam information was not received correctly.

[0108] In another embodiment, a feedback method according to an embodiment of the present disclosure includes, in response to the DCI being correctly received, sending an acknowledgement response to the DCI to the network device to indicate that the common beam information has been correctly received.

[0109] In a feedback method according to an embodiment of the present disclosure, a terminal can check whether the common beam information indicated in the DCI is received correctly, and if the common beam information is received correctly, can further determine whether the beam indicated in the common beam information indicated in the DCI is the same as the beam currently used by the terminal.

[0110] In an embodiment of the present disclosure, when determining whether a common beam indicated by common beam information indicated by DCI is the same as a beam currently used by the terminal, on the one hand, the terminal can decode the common beam information indicated by DCI, compare the common beam indicated by the common beam information indicated by DCI with the beam currently used by the terminal, and determine whether the common beam indicated by the common beam information indicated by DCI is the same as the beam currently used by the terminal. On the other hand, the DCI further includes bit information for indicating whether the common beam is a new beam. The terminal decodes the DCI, and determines whether the common beam indicated by the DCI is the same as the beam currently used by the terminal based on the bit information on whether the common beam indicated by the DCI is a new beam.

[0111] In one embodiment, in response to the common beam information being correctly received and the common beam indicated in the DCI being different from the beam currently being used by the terminal, an acknowledgment response to the DCI is sent to the network device.

[0112] 6 is a flowchart of a feedback method shown in an exemplary embodiment, which may be implemented alone or in combination with other embodiments of the present disclosure. As shown in FIG. 6, the feedback method is used in a terminal and includes the following steps:

[0113] In step S51, in response to the fact that the DCI has been received correctly and that the common beam indicated in the common beam information indicated in the DCI is different from the beam currently being used by the terminal, an acknowledgement response to the DCI is sent to the network device.

[0114] In one embodiment, in response to the DCI being received correctly and the common beam indicated in the common beam information indicated in the DCI being the same as the beam currently being used by the terminal, a feedback result for indicating that the DCI has been received correctly is not sent to the network device.

[0115] 7 is a flowchart of a feedback method shown in an exemplary embodiment, which may be implemented alone or in combination with other embodiments of the present disclosure. As shown in FIG. 7, the feedback method is used in a terminal and includes the following steps:

[0116] In step S61, in response to the DCI being received correctly and the common beam indicated in the common beam information indicated in the DCI being the same as the beam currently being used by the terminal, no feedback result for indicating that the DCI has been received correctly is sent to the network device.

[0117] In one example, in the feedback method according to the embodiment of the present disclosure, the terminal determines whether the terminal has successfully received common beam information indicated by the DCI depending on whether the terminal has successfully received the DCI. When the terminal determines that the terminal has successfully received the DCI, the terminal determines that the terminal has successfully received the common beam information indicated by the DCI, and determines whether the common beam indicated by the DCI is the same as the beam currently used by the terminal. When the common beam indicated by the DCI is the same as the beam currently used by the terminal, the terminal does not feed back an ACK and / or a NACK for the DCI signaling. For example, if the bit value of the feedback is 1, an ACK is identified, and if the bit value is 0, a NACK is identified, or if the bit value is 0, an ACK is identified, and if the bit value is 1, a NACK is identified. When the common beam indicated by the DCI is different from the beam currently used by the terminal, the terminal feeds back an ACK for the DCI signaling. When the terminal determines that the terminal has not successfully received the common beam information indicated by the DCI, the terminal feeds back a NACK for the DCI signaling.

[0118] In the feedback method according to the embodiment of the present disclosure, when a terminal transmits an acknowledgment response or a non-acknowledgment response to a DCI to a network device, the terminal may transmit the acknowledgment response or the non-acknowledgment response to the DCI to the network device based on bit resource information. Hereinafter, for ease of description, the bit resource information of the acknowledgment response or the non-acknowledgment response for indicating the DCI is referred to as first bit resource information.

[0119] 8 is a flowchart of a feedback method shown in an exemplary embodiment, which may be implemented alone or in combination with other embodiments of the present disclosure. As shown in FIG. 8, the feedback method is used in a terminal and includes the following steps:

[0120] In step S71, an acknowledgement response or a non-acknowledgement response to the DCI is transmitted to the network device based on the first bit resource information.

[0121] The first bit resource information is used to indicate an acknowledgement response or a non-acknowledgement response of the DCI. The first bit resource information may be understood as bit resource information for indicating a DCI HARQ ACK, and the DCI HARQ ACK may be understood as a DCI HARQ ACK for indicating common beam information.

[0122] In one embodiment, the first bit resource information includes bit resource information in a HARQ ACK codebook, and the HARQ ACK codebook includes a same type codebook or a different type codebook, for example, a first type codebook and / or a second type codebook. The first type codebook may be a fixed codebook, and the second type codebook may be a dynamic codebook.

[0123] In one embodiment, the first bit resource information may include a bit position.

[0124] In one example, the bit positions included in the HARQ codebook of the first bit resource information of the DCI HARQ ACK include a first type fixed codebook and a second type dynamic codebook.

[0125] In the feedback method according to the embodiment of the present disclosure, a bit position of the first bit resource information of the DCI HARQ ACK included in the HARQ codebook may be determined based on a bit position corresponding to one of the following:

[0126] A: A dynamically scheduled Transport Block (TB).

[0127] In the feedback method according to the embodiment of the present disclosure, the bit position of the first bit resource information of the DCI HARQ ACK included in the HARQ codebook is determined similarly to one dynamically scheduled TB, for example, the bit position of the DCI HARQ ACK in the HARQ codebook is determined as the first TB or the last TB.

[0128] B: Semi-statically scheduled (Semi-Persistent Scheduling, SPS) PDSCH.

[0129] In the feedback method according to the embodiment of the present disclosure, the bit position of the first bit resource information of the DCI HARQ ACK included in the HARQ codebook is determined in the same manner as that of one SPS PDSCH, for example, the bit position of the DCI HARQ ACK in the HARQ codebook is determined as the first SPS PDSCH or the last SPS PDSCH.

[0130] C: Dynamically scheduled Code Block Group (CBG).

[0131] In the feedback method according to the embodiment of the present disclosure, the bit position of the first bit resource information of the DCI HARQ ACK included in the HARQ codebook is determined in the same manner as a dynamically scheduled CBG, for example, the first CBG or the last CBG, to determine the bit position of the DCI HARQ ACK in the HARQ codebook.

[0132] D: Semi-statically scheduled physical downlink shared channel release message (SPS PDSCH release).

[0133] In the feedback method according to the embodiment of the present disclosure, the bit position of the first bit resource information of the DCI HARQ ACK included in the HARQ codebook is determined in the same manner as one SPS PDSCH release, for example, the bit position of the DCI HARQ ACK in the HARQ codebook is determined as the first SPS PDSCH release or the last SPS PDSCH release.

[0134] When the common beam indication information and the SPS PDSCH release do not appear at the same time, the HARQ feedback bit of the common beam indication information is placed at the position of the SPS PDSCH release and fed back, while the HARQ feedback bit position of the SPS PDSCH release is the same as the HARQ feedback bit position of the SPS PDSCH.

[0135] E: Secondary cell sleeve information (SCell dormancy).

[0136] In a feedback method according to an embodiment of the present disclosure, a bit position of the first bit resource information of DCI HARQ ACK included in the HARQ codebook is determined in the same manner as one SCell dormancy, for example, the bit position of DCI HARQ ACK in the HARQ codebook is determined as the first SCell dormancy or the last SCell dormancy.

[0137] In the related art, when determining the bit position of HARQ feedback corresponding to the TB or CBG or SPS PDSCH release of each PDSCH, first look at the earliest time unit, then look at the TB or CBG or SPS PDSCH release of each PDSCH on the serving cell with the smallest serving cell index in the same time unit, and for the same serving cell, the HARQ feedback bit based on TB is in one of the sub-codebooks, and the HARQ feedback bit based on CBG is in the other sub-codebook. That is, each HARQ feedback bit has a corresponding position, so as given above, the HARQ feedback for DCI indicated by the beam indication information can be placed at the same position as one of the above TB, CBG, SPS PDSCH release and SCell dormancy.

[0138] In one example, if cell#1 is configured with CBG transmission and one PDSCH supports at most 4 CBGs, and cell#2 is configured with CBG transmission and one PDSCH supports at most 6 CBGs, then each dynamically scheduled PDSCH in sub-codebook 2 corresponds to 6-bit ACK / NACK. If cell#3 is not configured with CBG transmission and one PDSCH supports at most 2 TBs, then each dynamically scheduled PDSCH in sub-codebook 1 corresponds to 2-bit ACK / NACK. The ACK / NACK corresponding to the dynamically scheduled PDSCH in sub-codebook 1 is at the front, and the ACK / NACK corresponding to the SPS PDSCH is mapped to the end of sub-codebook 1, and one SPS PDSCH corresponds to 1-bit ACK / NACK information. bi,j in FIG. 9 identifies the j-th bit of ACK / NACK information corresponding to PDSCH i. For example, b2,1 in FIG. 9 identifies the 1-th bit of ACK / NACK information corresponding to PDSCH 2. b2,2 in FIG. 9 identifies the second bit of ACK / NACK information corresponding to PDSCH 2.

[0139] In a feedback method according to an embodiment of the present disclosure, a terminal can determine the time to use a common beam indicated in the common beam information.

[0141] In step S81, in response to the common beam indicated in the DCI being the same as the beam currently used by the terminal and the beam receiving the control resource set being different from the common beam, the common beam is used a first time after receiving the DCI.

[0142] In one example, if the common beam indicated by DCI is the same as the beam currently used by the terminal (the common beam is the old beam), and the beam receiving CORESET is different from this common beam, the time to be used is the T0 time after the DCI signaling. The T0 time may be the same as the time duration of R16, and is not limited here.

[0144] In step S91, in response to the common beam indicated in the DCI being different from the beam currently being used by the terminal, the terminal uses the common beam a second time after receiving the DCI, or a third time after transmitting the feedback result.

[0145] In one example, the common beam indicated by the DCI is different from the beam currently used by the terminal (the common beam is a new beam), and the time to use is T1 time after the DCI signaling and / or T2 time after the HARQ ACK feedback. The T1 time may be the same as the time duration of R16, or may further include the time of the HARQ ACK feedback, and is not limited here.
