Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to beam pointing methods, beam pointing devices and storage media. Background Technology

[0002] In New Radio (NR) technologies, such as communication bands in frequency range 2, beam-based transmission and reception are required to ensure coverage due to the rapid attenuation of high-frequency channels. When network devices (e.g., base stations) have multiple Transmission Reception Points (TRPs), multiple TRPs can be used to provide services to terminals, including using multiple TRPs to transmit the physical downlink control channel (PDCCH) to terminals.

[0003] In related technologies, schemes using multiple TRPs to send PDCCHs can configure the terminal's transmission configuration indication (TCI) state for receiving the PDCCH, i.e., configuring the receive beam. For example, configuring a Control Resource Set (CORESET) for the terminal and configuring the corresponding TCI state for the CORESET. There are schemes that configure different and associated CORESETs for the terminal to enable multiple TRPs to send PDCCHs to the terminal. However, if the TCI state indication for each associated CORESET is independent, it will lead to significant signaling overhead and latency. Summary of the Invention

[0073] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0074] The data transmission method provided in this disclosure can be applied to... Figure 1 The wireless communication system shown. (See attached image) Figure 1 As shown, this wireless communication system includes a terminal and a network device. The terminal connects to the network device via wireless resources and transmits and receives data.

[0075] Understandable Figure 1 The wireless communication system shown is for illustrative purposes only. A wireless communication system may also include other network devices, such as core network equipment, wireless relay equipment, and wireless backhaul equipment. Figure 1 Not shown in the diagram. This disclosure does not limit the number of network devices and terminals included in the wireless communication system.

[0076] It is further understood that the wireless communication system of this disclosure is a network providing wireless communication functionality. The wireless communication system can employ 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. Based on factors such as capacity, speed, and latency, networks can be categorized as 2G networks, 3G networks, 4G networks, or future evolution networks, such as 5G networks. 5G networks can also be referred to as New Radio (NR). For ease of description, this disclosure may sometimes simply refer to the wireless communication network as a network.

[0077] Furthermore, the network device involved in this disclosure can also be referred to as a wireless access network device. This wireless access network device can be: a base station, an evolved Node B (eNB), a home base station, an access point (AP) in a Wireless Fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP), etc. It can also be a gNB in ​​an NR system, or a component or part of a base station. When it is a vehicle-to-everything (V2X) communication system, the network device can also be an in-vehicle device. It should be understood that the specific technologies and device forms used in the embodiments of this disclosure are not limited.

[0078] Furthermore, the terminal involved in this disclosure can also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., and is a device that provides voice and / or data connectivity to a user. For example, a terminal can be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, some examples of terminals include: smartphones (Mobile Phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be an in-vehicle device. It should be understood that the embodiments of this disclosure do not limit the specific technology or specific device form adopted by the terminal.

[0079] In this disclosure, data transmission between network devices and terminals is based on beamforming. During beamforming data transmission, network devices (e.g., base stations) can use multiple TRPs (multiple TRPs are also called Multi-TRPs) to send PDCCHs to terminals. In related technologies, when a network device (e.g., a base station) uses one TRP to send a PDCCH to a terminal, it configures the TCI state for the terminal to receive that PDCCH. For example, the configuration method is as follows: configure a CORESET, such as CORESET#1, for the terminal, and configure the TCI state used by the terminal when receiving PDCCHs from resources in CORESET#1 as TCI#1. Also, configure a Search Space set (SS set) for the terminal and associate it with CORESET#1. When the terminal receives PDCCHs from resources in the SS set, it uses the beam corresponding to TCI#1 for reception. Currently, each SS set can only be associated with one CORESET, and each CORESET is configured with only one TCI state (TCI state is also called TCI state).

[0080] Furthermore, to improve the reliability of PDCCH by enabling multiple TRPs to send the same PDCCH, there are currently several methods:

[0081] Method 1: Configure two TCI states for a CORESET. Configure one SS set associated with the CORESET, then the SS set can correspond to two TCI states; or configure two SS sets associated with the CORESET, each SS set corresponding to one TCI state.

[0082] Method 2: Configure an SS set that is associated with two CORESETs. Each CORESET corresponds to a TCI state, so the SS set can correspond to two TCI states.

[0083] Method 3: Configure two CORESETs, each corresponding to a TCI state, and then configure SSsets to be associated with the two CORESETs respectively. That is, two SSsets are configured, each associated with a different CORESET and a different TCI state.

[0084] For methods two and three, since different CORESETs are used and the TCI status indication of each CORESET is independent, if the update indications of the TCI status of these two associated CORESETs continue to be independent, it will bring large signaling overhead and latency. Moreover, there may be a phenomenon where the terminal receives one update instruction for the two TCI statuses successfully and the other fails to receive it.

[0085] In view of this, embodiments of the present disclosure provide a beam indication method that uses joint indication signaling to indicate the beam information of multiple control resource sets associated with PDCCH retransmission, thereby reducing signaling overhead and latency, and ensuring the consistency of beam updates for multiple control resource sets.

[0086] For ease of description, the signaling used to indicate beam information of multiple control resource sets in this embodiment is referred to as the first signaling.

[0087] Figure 2 This is a flowchart illustrating a beam pointing method according to an exemplary embodiment, such as... Figure 2 As shown, the beam pointing method used in the terminal includes the following steps.

[0088] In step S11, the first signaling is determined.

[0089] The first signaling is used to indicate beam information for multiple control resource sets.

[0090] In this embodiment of the disclosure, the first signaling may be an indication signaling sent by a network device. This indication signaling is used to indicate beam information of multiple (typically two) CORESETs.

[0091] The terminal receives indication signaling sent by the network device, which is used to indicate the beam information of multiple (typically two) CORESETs.

[0092] In this embodiment of the disclosure, beam information of multiple control resource sets is indicated by a first signaling signal. This enables the use of joint indication signaling to indicate the beam information of multiple control resource sets associated with PDCCH retransmission, thereby reducing signaling overhead and latency, and ensuring the consistency of beam updates for multiple control resource sets. For example, for two associated cores used for PDCCH retransmission, joint indication signaling is used to indicate the beam information of the two cores, thereby reducing signaling overhead and latency, and ensuring the consistency of beam updates for the two cores.

[0093] Figure 3 This is a flowchart illustrating a beam pointing method according to an exemplary embodiment, such as... Figure 3 As shown, the beam pointing method used in the terminal includes the following steps.

[0094] In step S21, a first signaling is determined, wherein the first signaling is used to indicate the beam information corresponding to the first number of control resource sets respectively.

[0095] In one example, the first signaling can be used to indicate the beam information corresponding to each of the two CORESETs.

[0096] In this embodiment of the disclosure, the beam information corresponding to the control resource set may include a transmission configuration indication state ID (TCI state ID) or a corresponding control resource set identifier (CORESETID).

[0097] In this embodiment of the disclosure, the TCI state ID corresponds to the CORESET ID, and each TCI state ID corresponds to one TCI state. Each TCI state corresponds to a reference signal ID. The reference signal ID is used to instruct the terminal to use the same receive beam as the one used to receive the reference signal to receive the PDCCH transmitted within the CORESET resource corresponding to that TCI state ID.

[0098] The CORESET ID corresponding to the TCI state ID can be understood as the beam corresponding to the TCI state ID being used to receive the PDCCH transmitted on the CORESET resource corresponding to the CORESET ID.

[0099] For ease of description in this embodiment, the TCIstate ID indicated in the first signaling and corresponding to the CORESET ID is referred to as the target TCI state ID. Each target TCI state ID corresponds to one TCI state. Each TCI state corresponds to one reference signal ID. The reference signal ID is used to instruct the terminal to use the same receiving beam as the one used to receive the reference signal to receive the PDCCH transmitted within the CORESET resource corresponding to the target TCI state ID.

[0100] Figure 4 This is a flowchart illustrating a beam pointing method according to an exemplary embodiment, such as... Figure 4 As shown, the beam pointing method used in the terminal includes the following steps.

[0101] In step S31, a first signaling is determined, wherein the first signaling is used to indicate a first number of target TCI stateIDs and a CORESET ID corresponding to each target TCI stateID in the first number of target TCI stateIDs, and each target TCI stateID corresponds to a TCI state.

[0102] In this embodiment of the present disclosure, in response to the first signaling indicating a first number of CORESET IDs, all CORESET IDs in the first number of CORESET IDs may be explicitly indicated. Alternatively, in response to the first signaling indicating a first number of CORESET IDs, all CORESET IDs in the first number of CORESET IDs may be implicitly indicated. Or, in response to the first signaling indicating a first number of CORESET IDs, some of the first number of CORESET IDs may be explicitly indicated, while others may be implicitly indicated.

[0103] The display indication can be understood as directly indicating the CORESET ID, or using the bit corresponding to the CORESET ID to indicate the CORESET ID, that is, each or more bits at different positions in the first signaling correspond to a different CORESET ID.

[0104] Implicit indication can be understood as an indirect indication of the CORESET ID. For example, when the resources of the first CORESET are used to send the first signaling indication, it implicitly indicates that the CORESET ID corresponding to the target TCI state ID of the first signaling indication includes the CORESET ID of the first CORESET.

[0105] One implementation method, which implicitly indicates the CORESET ID, is applicable to DCI signaling indication.

[0106] The present disclosure provides a beam indication method in which the first signaling can be a Medium Access Control (MAC) Control Element (CE) signaling.

[0107] In one example, the MAC CE signaling indicates the beam information corresponding to each of the two CORESETs.

[0108] In one example, the MAC CE includes indications of two active target TCI state IDs and an indication of a CORESET ID corresponding to each target TCI state ID. Each TCI state ID corresponds to one TCI state. Each TCI state corresponds to a reference signal ID, which instructs the terminal to use the same receive beam as the one used to receive the PDCCH transmitted within the CORESET resource corresponding to that target TCI state ID.

[0109] In one embodiment of this disclosure, the target TCI state ID can be indicated by Radio Resource Control (RRC) signaling or MAC CE signaling.

[0110] The target TCI state ID is the target TCI state ID activated by MAC CE signaling in the TCI state ID list.

[0111] For example, the first signaling also includes RRC signaling, which indicates the TCI state ID list for each CORESET, and MAC CE signaling, which indicates the target TCI state ID for each CORESET, where the target TCI state ID is a TCI state ID in the TCI state ID list for each CORESET. The TCI state ID lists indicated by the RRC signaling for each CORESET can be the same or different; this is not restricted here.

[0112] The beam indication method provided in this embodiment can be a first signaling signal, which can be a downlink control information (DCI) signaling.

[0113] In one example, DCI signaling indicates beam information corresponding to two CORESETs.

[0114] In one example, the DCI signaling includes indications of two target TCI state IDs and an indication of a CORESET ID corresponding to each target TCI state ID. Each TCI state ID corresponds to a TCI state. Each TCI state corresponds to a reference signal ID, which instructs the terminal to use the same receive beam as the one used to receive the reference signal to receive the PDCCH transmitted within the CORESET resource corresponding to that target TCI state ID.

[0115] The target TCI state ID is one of multiple TCI state IDs indicated by the MAC CE signaling.

[0116] For example, the first signaling also includes MAC CE signaling, which contains indications of two CORESET IDs and multiple active TCI state IDs corresponding to each CORESET ID. For example, the MAC CE activates multiple TCI state IDs, and one or more of these activated TCI state IDs can serve as target TCI state IDs. The DCI signaling indicates one target TCI state ID for each CORESET ID. Each TCI state ID corresponds to one TCI state. The MAC CE signaling activating the multiple TCI state IDs corresponding to the two CORESET IDs can be the same MAC CE signaling or different MAC CE signaling; this is not restricted here.

[0117] In one implementation, for each CORESET ID, the multiple TCI state IDs indicated by the MAC CE signaling are multiple TCI state IDs in a TCI state ID list. For example, the first signaling also includes RRC signaling, which indicates the TCI state ID list corresponding to each CORESET, and the MAC CE signaling indicates multiple TCI state IDs in the TCI state ID list corresponding to each CORESET. The TCI state ID list indicated by the RRC signaling for each CORESET can be the same or different; this is not limited here.

[0118] Figure 5 This is a flowchart illustrating a beam pointing method according to an exemplary embodiment, such as... Figure 5 As shown, the beam pointing method used in the terminal includes the following steps.

[0119] In step S41, a first signaling is determined. The first signaling is used to indicate the identifier (abbreviated as CORESET pair ID) of the control resource set pair corresponding to the first number of target TCI state IDs, which includes a first number of target TCI state IDs. The CORESET pair includes the CORESET corresponding to each target TCI state ID in the first number of target TCI state IDs, and each target TCI state ID corresponds to a TCI state.

[0120] In this embodiment of the disclosure, in response to the first signaling indication CORESET pair ID, the CORESET pair ID may be implicitly indicated or explicitly indicated.

[0121] The display indication can be understood as directly indicating the CORESET pair ID, or using the bit corresponding to the CORESET pair ID to indicate the CORESET pair ID, that is, each or more bits at different positions in the first signaling correspond to a different CORESET pair ID.

[0122] Implicit indication can be understood as an indirect indication of the CORESET pair ID. For example, sending the first signaling using resources from any control resource set contained in the CORESET pair indicates that the target TCI state ID indicated by the first signaling is the beam information used to indicate the CORESET pair.

[0123] The present disclosure provides a beam indication method in which the first signaling can be MAC CE signaling.

[0124] In one example, the MAC CE signaling indicates the beam information corresponding to each of the two CORESETs.

[0125] In one example, the MAC CE signaling indicates two active target TCI state IDs, and a CORESET pair ID corresponding to the two active target TCI state IDs. Each target TCI state ID corresponds to one TCI state.

[0126] In one embodiment of this disclosure, the target TCIstate ID can be indicated by RRC signaling or MAC CE signaling.

[0127] For example, the first signaling also includes RRC signaling, which indicates the TCI state ID list for each CORESET, and MAC CE indicates the target TCI state ID for each CORESET, where the target TCI state ID is one of the TCI state IDs in the TCI state ID list for each CORESET. The TCI state ID lists indicated by the RRC signaling for each CORESET can be the same or different; this is not restricted here.

[0128] In this embodiment of the disclosure, the CORESET ID corresponding to the CORESET pair can be indicated by RRC signaling or MAC CE signaling. For example, the first signaling also includes RRC signaling, which further indicates the two CORESET IDs corresponding to the CORESET pair ID.

[0129] The present disclosure provides a beam indication method in which the first signaling can be DCI signaling.

[0130] In one example, DCI signaling indicates beam information corresponding to two CORESETs.

[0131] For example, DCI signaling includes indications of two target TCI state IDs and a CORESET pair ID corresponding to the two target TCI state IDs. Each TCI state ID corresponds to one TCI state. Each TCI state corresponds to a reference signal ID, which is used to instruct the terminal to use the same receive beam as the one used to receive the reference signal to receive the PDCCH transmitted within the CORESET resource corresponding to the target TCI state ID.

[0132] The target TCI state ID is one of multiple TCI state IDs indicated by the MAC CE signaling.

[0133] For example, the first signaling also includes MAC CE signaling, which contains indications of two CORESET IDs and multiple active TCI state IDs corresponding to each CORESET ID. For example, one or more of the multiple TCI state IDs activated by the MAC CE can be used as the target TCI state ID. The DCI signaling indicates a target TCI state ID for each CORESET ID. Each TCI state ID corresponds to one TCI state. The MAC CE signaling activating the multiple TCI state IDs corresponding to the two CORESET IDs can be the same MAC CE signaling or different MAC CE signaling; this is not restricted here.

[0134] In this embodiment of the disclosure, the CORESET ID corresponding to the CORESET pair can be indicated by RRC signaling and / or MAC CE signaling. For example, the first signaling also includes MAC CE signaling, which further indicates the two CORESET IDs corresponding to the CORESET pair ID. As another example, the first signaling also includes RRC signaling, which further indicates the two CORESET IDs corresponding to the CORESET pair ID.

[0135] In one embodiment of this disclosure, the target TCIstate ID can be indicated by RRC signaling or MAC CE signaling.

[0136] For example, the first signaling also includes RRC signaling, which indicates the TCI state ID list corresponding to each CORESET, and MAC CE signaling, which indicates multiple TCI state IDs in the TCI state ID list corresponding to each CORESET. The TCI state ID lists indicated by the RRC signaling for each CORESET can be the same or different; this is not restricted here.

[0137] In a beam indication method provided in this disclosure, the first signaling includes DCI signaling, which indicates a bit codeword (abbreviated as codepoint). The first signaling also includes a second MAC CE signaling, which indicates the CORESET ID or CORESET pair ID corresponding to the codepoint given by the DCI signaling, and the TCIstate ID. For example, the DCI signaling directly gives a codepoint, while the second MAC CE signaling indicates: which TCI state of which CORESET ID each codepoint corresponds to, or which TCI state of which two CORESET IDs it corresponds to, or which TCI state ID or which two TCI state IDs it corresponds to, or which TCI state ID or which two TCI state IDs it corresponds to, and indicates the CORESET ID corresponding to the CORESET pair ID. Further, if the second MAC CE signaling does not indicate the CORESET ID corresponding to the CORESET pair ID, then the RRC signaling indicates the CORESET ID corresponding to the CORESET pair ID.

[0138] Figure 6 This is a flowchart illustrating a beam pointing method according to an exemplary embodiment, such as... Figure 6 As shown, the beam pointing method used in the terminal includes the following steps.

[0139] In step S51, a first signaling is determined, which is used to indicate a target TCI state ID and a CORESET pair ID corresponding to the target TCI state ID, wherein the target TCI state ID is used to identify a first number of TCI states.

[0140] The CORESET pair ID includes the CORESET corresponding to each TCI state in the first number of TCI states.

[0141] In this embodiment of the disclosure, in response to the first signaling indication CORESET pair ID, the CORESET pair ID may be implicitly indicated or explicitly indicated.

[0142] The display indication can be understood as directly indicating the CORESET pair ID, or using the bit corresponding to the CORESET pair ID to indicate the CORESET pair ID, that is, each or more bits at different positions in the first signaling correspond to a different CORESET pair ID.

[0143] Implicit indication can be understood as an indirect indication of the CORESET pair ID. For example, sending the first signaling using resources from any control resource set contained in the CORESET pair indicates that the target TCI state ID indicated by the first signaling is the beam information used to indicate the CORESET pair.

[0144] The present disclosure provides a beam indication method in which the first signaling can be MAC CE signaling.

[0145] In one example, the MAC CE signaling indicates beam information corresponding to each of the two CORESETs.

[0146] For example, MAC CE signaling indicates an active TCI state ID and a corresponding CORESET pair ID. A TCI state ID contains two TCI states, and each TCI state corresponds to one of the two CORESETs associated with a CORESET pair ID.

[0147] In this embodiment of the disclosure, the CORESET ID corresponding to the CORESET pair can be indicated by RRC signaling or MAC CE signaling. For example, the first signaling also includes RRC signaling, which indicates the two CORESET IDs corresponding to the CORESET pair ID.

[0148] In one embodiment of this disclosure, the target TCIstate ID can be indicated by RRC signaling or MAC CE signaling.

[0149] For example, the first signaling also includes RRC signaling, which indicates a list of TCI state IDs corresponding to CORESET pair IDs. Each TCI state ID in this list can indicate only one CORESET's TCI state or indicate the TCI states corresponding to two CORESETs respectively. If it indicates only one, it means that the other one is unchanged. Alternatively, each TCI state ID in this list indicates the TCI states corresponding to two CORESETs respectively, but one of the two TCI states corresponding to different TCI state IDs may have the same TCI state for one of the CORESETs.

[0150] The present disclosure provides a beam indication method in which the first signaling can be DCI signaling.

[0151] In one example, DCI signaling indicates beam information corresponding to two CORESETs.

[0152] For example, DCI signaling includes an indication of a target TCI state ID and a CORESET pair ID corresponding to that target TCI state ID. The target TCI state ID contains two TCI states, and each TCI state corresponds to one of the two CORESETs corresponding to a CORESET pair ID.

[0153] The target TCI state ID is one of several TCI state IDs indicated by the MAC CE signaling.

[0154] For example, MAC CE signaling includes an indication of a CORESET pair ID, and multiple active target TCI state IDs corresponding to the CORESET pair ID. The target TCI state ID contains two TCI states, and each TCI state corresponds to one of the two CORESETs corresponding to a CORESET pair ID.

[0155] In this embodiment of the disclosure, the CORESET ID corresponding to the CORESET pair can be indicated by RRC signaling or MAC CE signaling. For example, the first signaling also includes RRC signaling, which indicates the two CORESET IDs corresponding to the CORESET pair ID. As another example, the first signaling also includes MAC CE signaling, which indicates the two CORESET IDs corresponding to the CORESET pair ID.

[0156] In one embodiment of this disclosure, the target TCIstate ID can be indicated by RRC signaling or MAC CE signaling.

[0157] For example, RRC signaling indicates a list of TCI state IDs corresponding to CORESET pair IDs. Each TCI state ID in this list can indicate only one CORESET's TCI state or indicate the TCI states corresponding to two CORESETs respectively. If it indicates only one, it means the other one is unchanged. Alternatively, each TCI state ID in this list indicates the TCI states corresponding to two CORESETs respectively, but one of the two CORESETs corresponding to different TCI state IDs may have the same TCI state.

[0158] The beam indication method provided in this disclosure, when using multiple CORESET PDCCH candidates to repeatedly transmit Multi-TRP PDCCH, performs joint beam indication for multiple associated CORESETs, which can reduce signaling overhead and reduce latency.

[0159] Figure 7 This is a flowchart illustrating a beam pointing method according to an exemplary embodiment, such as... Figure 7 As shown, the beam pointing method used in a network includes the following steps.

[0160] In step S61, a first signaling is sent, which is used to indicate the beam information of multiple CORESETs.

[0161] In this embodiment of the present disclosure, the first signaling sent by the network device is used to indicate beam information of multiple (typically 2) CORESETs.

[0165] In one embodiment, the beam indication method provided in this disclosure includes a first signaling signaling for indicating a first number of target TCI state IDs and an identifier (abbreviated as CORESET pair ID) of a control resource set pair corresponding to the first number of target TCI state IDs. The CORESET pair includes the CORESET corresponding to each target TCI state ID in the first number of target TCI state IDs, and each target TCI state ID corresponds to one TCI state.

[0166] In one embodiment, the beam indication method provided in this disclosure includes a first signaling used to indicate a target TCI state ID and a CORESET pair ID corresponding to the target TCI state ID, wherein the target TCI state ID is used to identify a first number of TCI states.

[0167] Furthermore, in one aspect, the beam indication method provided in the embodiments of this disclosure includes MAC CE signaling as the first signaling.

[0168] Wherein, in response to the first signaling including MAC CE signaling, the target TCI state ID is the target TCI state ID activated by the MAC CE signaling in the TCI state ID list.

[0169] On the other hand, in the beam indication method provided in the embodiments of this disclosure, the first signaling includes DCI signaling.

[0170] The response to the first signaling includes DCI signaling. The target TCI state ID is one of several TCI state IDs indicated by the MAC CE.

[0171] In one implementation, the multiple TCI state IDs indicated by the MAC CE are multiple TCI state IDs in a list of TCI state IDs.

[0172] In one embodiment, the beam indication method provided in this disclosure includes a first signaling signaling method comprising DCI signaling, which is used to indicate a codepoint. The first signaling also includes a second MAC CE. The second MAC CE is used to indicate the CORESET ID or CORESET pair ID corresponding to the codepoint, and the TCI state ID.
