[0030] Communication system architecture

[0031] FIG1 is a diagram illustrating an exemplary system architecture of a wireless communication system 100 to which embodiments of the present application may be applied. The wireless communication system 100 may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120.

[0032] FIG1 exemplarily shows a network device and two terminal devices. Optionally, the wireless communication system 100 may include one or more network devices 110 and / or one or more terminal devices 120. For one network device 110, the one or more terminal devices 120 may all be located within the network coverage of the network device 110, or all be located outside the network coverage of the network device 110, or some may be located within the network coverage of the network device 110 and others outside the network coverage of the network device 110. This is not limited in the embodiments of the present application.

[0033] Optionally, the wireless communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present application.

[0034] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: fifth generation (5G) system or new radio (NR) system, long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, etc. The technical solutions provided in this application can also be applied to future communication systems, such as the sixth generation mobile communication system, satellite communication system, etc.

The cellular phone and smart home devices communicate without relaying the communication signal through the base station.

[0036] The network device in the embodiments of the present application may be a device for communicating with a terminal device, and may also be referred to as an access network device or a radio access network device. For example, the network device may be a base station. The network device in the embodiments of the present application may refer to a radio access network (RAN) node (or device) that connects a terminal device to a wireless network. A base station can broadly cover various names as follows, or be replaced with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmission point (TP), master station MeNB, secondary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof. A base station can also refer to a communication module, a modem or a chip used to be set in the aforementioned device or apparatus. The base station can also be a mobile switching center and a device that performs base station functions in device-to-device D2D, vehicle-to-everything (V2X), and machine-to-machine (M2M) communications, a network-side device in a 6G network, or a device that performs base station functions in future communication systems. The base station can support networks with the same or different access technologies. The embodiments of this application do not limit the specific technology and specific device form used by the network equipment.

[0037] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station.

[0038] In some deployments, the network device in the embodiments of the present application may refer to a CU or a DU, or the network device may include a CU and a DU. The gNB may also include an AAU.

[0039] The network equipment and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; they can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the scenarios in which the network equipment and terminal devices are located.

[0040] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0041] Sideline communication mode

[0042] Sidelink communication refers to a communication technology based on sidelink (SL). Sidelink communication can be, for example, D2D or V2X. In traditional cellular systems, communication data is received or sent between terminal devices and network devices, while sidelink communication supports direct transmission of communication data between terminal devices. Compared to traditional cellular communication, direct transmission of communication data between terminal devices can achieve higher spectrum efficiency and lower transmission latency. For example, the Internet of Vehicles system uses sidelink communication technology.

[0043] Certain standards or protocols (such as the 3rd Generation Partnership Project (3GPP)) define two modes (or transmission modes) of sideline communication: a first mode (or mode A, mode 1, etc.) and a second mode (or mode B, mode 2, etc.).

[0044] In the first mode, the resources of the terminal device (the resources mentioned in this application may also be referred to as transmission resources, such as time-frequency resources) are allocated by the network device. The terminal device can send data on the side link according to the resources allocated by the network device. The network device can allocate resources for a single transmission to the terminal device, or it can allocate resources for semi-static transmission to the terminal device. This first mode can be applied to scenarios covered by network devices, such as the scenario shown in Figure 2. In the scenario shown in Figure 2, the terminal device 120 is within the network coverage of the network device 110, so the network device 110 can allocate resources used in the side transmission process to the terminal device 120.

[0045] In the second mode, the terminal device can autonomously select one or more resources from a resource pool (RP). The terminal device can then perform side transmission based on the selected resources. For example, in the scenario shown in FIG3 , the terminal device 120 is located within the network coverage of the network device 110, and the terminal device 120 can also autonomously select one or more resources from the resource pool configured by the network device 110 for side transmission. For another example, in the scenario shown in FIG4 , the terminal device 120 is located outside the network coverage of the network device 110, and therefore, the terminal device 120 can autonomously select one or more resources from the pre-configured resource pool for side transmission.

[0046] Different research stages of side communication

[0047] In 3GPP, sideline communications can be divided into different research phases, and the research contents in different research phases vary.

[0048] In Release 12 (Rel-12) / Rel-13, sidelink communications (e.g., D2D) primarily focus on proximity-based service (ProSe) scenarios, for example, focusing on public safety services within proximity-based services. In ProSe services, the location of resource pools in the time domain can be configured to differentiate the transmission / reception of sidelink communication data between terminal devices. For example, resource pools can be configured to be discontinuous in the time domain, allowing terminal devices to discontinuously transmit / receive sidelink communication data on the sidelink, thereby achieving power savings.

[0049] In Rel-14 / 15, sidewalk communication is primarily studied for V2X scenarios, or more specifically, vehicle-to-vehicle communication scenarios. For example, research focuses on relatively high-speed vehicle-to-vehicle and vehicle-to-pedestrian communication services. In V2X, since the onboard system has a continuous power supply, power efficiency is not the primary issue. Instead, reducing data transmission latency is the primary concern. As an implementation method, in V2X, terminal devices can continuously transmit and receive sidewalk communication data to reduce data transmission latency.

[0050] In Rel-14, sideline communication also targets wearable device scenarios (further enhancements to device-to-device, FeD2D). For example, the focus is on scenarios where wearable devices access network devices through mobile phones. It should be understood that FeD2D is mainly aimed at low mobile speed and low-power access scenarios. During the FeD2D research process, in the pre-research stage, 3GPP determined that network equipment can configure the DRX (discontinuous reception) parameters of remote terminals through a relay terminal. However, because this topic did not enter the standardization stage, the specific details of how to configure DRX have not been determined.

[0051] NR has further enhanced the research on sidewalk communications based on LTE. For example, NR V2X has expanded the application scenarios of LTE V2X. NR V2X is no longer limited to broadcast scenarios, but has further expanded the application scenarios of V2X to unicast and multicast scenarios, so as to study the application of V2X in different application scenarios.

[0052] NR V2X can also define the two modes of side communication mentioned above. Furthermore, the terminal device can be in a mixed mode, that is, it can use the first mode to acquire resources and the second mode to acquire resources at the same time.

[0053] In addition to being applicable to scenarios where there is no feedback and the terminal device autonomously initiates hybrid automatic repeat request (HARQ) retransmission, NR V2X can also be applied to scenarios where HARQ retransmission is based on feedback, for example, in a unicast communication scenario, or in a multicast communication scenario.

[0054] Similar to LTE V2X, in NR V2X, since the on-board system has a continuous power supply, power efficiency is not the main issue to be solved in the V2X scenario. Instead, how to reduce the latency of data transmission is the main issue that needs to be solved in the V2X scenario. As an implementation method, in V2X, terminal devices can reduce the latency of data transmission by continuously sending / receiving side communication data.

[0055] Downlink beam management

[0056] When network devices and terminal devices communicate using analog beams, achieving good communication quality requires pairing (or aligning) the transmit and receive beams to form a beam pair. Therefore, beam management addresses the issue of determining one or more beam pairs for communication between network devices and terminal devices, ensuring optimal channel quality for the communication links corresponding to these beam pairs.

[0057] Taking downlink beam management as an example, the pairing of transmit and receive beams involves the network device's downlink transmit beam and the terminal device's downlink receive beam. In other words, from the network's perspective, the network device needs to know which transmit beam is best for the terminal device, which relies on the terminal device's measurement and reporting of the downlink transmit beam. From the terminal device's perspective, the terminal device needs to know which downlink transmit beam or beams of the network device are best for the terminal device's transmission. At the same time, for a specific downlink transmit beam, the terminal device (for example, a millimeter-wave terminal device) may also need to consider which receive beam to use for better reception performance, which also relies on the terminal device's measurement.

[0058] In other words, beam management requires beam measurement. Beam measurement is a crucial step in beam management. The fundamental issues that need to be addressed during measurement include the measurement object, the measurement metric, and how to report the measurement results. These are discussed below.

[0059] Measurement object: A beam is an objectively existing physical entity. However, in standardized protocols (especially physical layer protocols), logical concepts are generally considered and specific physical entities are not limited. Therefore, the measurement of a beam can generally be achieved by measuring the reference signal transmitted on the beam. In other words, when measuring a beam, the measurement object may refer to the reference signal transmitted on the beam, that is, it is necessary to determine which reference signal or signals are used to measure the beam. Taking the NR system as an example, a large number of measurement-related functions (for example, mobility-related measurements, channel state information measurements, etc.) are based on the channel state information reference signal (CSI-RS) / synchronization signal block (SSB) signal. For downlink beam management, the NR system also supports beam measurement based on CSI-RS and SSB signals. Exemplarily, the reference signal measured in downlink beam management can be a terminal device-specific (UE-specific) CSI-RS and / or SSB, that is, the terminal device can measure the UE-specific CSI-RS, or measure the SSB, or measure the UE-specific CSI-RS and SSB at the same time according to the configuration information of the network device.

[0060] Measurement metric (or measurement quantity): The measurement metric can be used to characterize the measurement result. The measurement metric for downlink beam management may include multiple types. For example, in Rel-15, the reference signal receiving power (RSRP) can be used as the measurement metric for downlink beam management, for example, the RSRP (L1-RSRP) of layer 1 (L1) is used as the measurement metric; for another example, in Rel-16, the signal to interference plus noise ratio (SINR) is also introduced as the measurement metric for downlink beam management, for example, L1-SINR is used as the measurement metric. Therefore, in the downlink beam management process, if the terminal device supports downlink beam measurement based on L1-RSRP and L1-SINR at the same time, the network device can instruct the terminal device through configuration information which measurement metric to use, such as L1-RSRP or L1-SINR.

[0061] Measurement reporting method: After measuring a beam, a terminal device can report K (K ≥ 1) pieces of information to the network device based on the measurement results. Each piece of information can include beam indication information and corresponding measurement metric information (or measurement quantity, measurement value, etc.). For example, the beam indication information can be, for example, a CSI-RS resource identifier, an SSB number (or SSB label), etc.; the measurement metric information can be, for example, L1-RSRP, L1-SINR, etc. In some implementations, when K > 1, the quantized result of the maximum value among the K measurement metric information can be reported directly, and the difference between the other K-1 measurement metric information and the maximum value is quantized and reported, that is, the difference values ​​of the other K-1 measurement metric information are reported. Taking L1-RSRP as an example, the quantized result of the maximum value among the K L1-RSRP values ​​is reported directly, and the difference between the other K-1 L1-RSRP values ​​and the maximum L1-RSRP value is quantized and reported, that is, the difference values ​​of the other K-1 L1-RSRP values ​​are reported. A similar reporting method may also be used for the measurement of L1-SINR, which is not limited in the embodiments of the present application.

[0062] Beam pointing

[0063] Taking the NR system as an example, for beam indication, the physical downlink shared channel (PDSCH) and the physical downlink control channel (PDCCH) can independently use their own beams to provide greater flexibility and freedom for actual commercial system optimization.

[0064] In NR systems, beam indication can be achieved through the transmission configuration indicator (TCI) state and the quasi-co-location (QCL) concept. As an implementation method, network equipment can configure a corresponding TCI state for each downlink signal or downlink channel, indicating the QCL reference signal corresponding to the target downlink signal or target downlink channel, so that the terminal device can receive the target downlink signal or target downlink channel based on the QCL reference signal.

[0065] As an implementation, the TCI state may include one or more of the following configurations: a TCI state identifier (ID); QCL information 1; and QCL information 2. The TCI state ID may be used to identify the TCI state. The QCL information (e.g., QCL information 1, QCL information 2, etc.) may include: a QCL type configuration and a QCL reference signal configuration.

[0066] In some embodiments, the QCL type configuration may be one of QCL type A, QCL type B, QCL type C, or QCL type D. However, the embodiments of the present application are not limited thereto, and when the QCL type includes other types, the QCL type configuration may also be other types.

[0067] In some embodiments, the QCL reference signal configuration may include one or more of the following information: a cell ID where the reference signal resides, a bandwidth part (BWP) ID, and a reference signal identifier. For example, if the reference signal is a CSI-RS or SSB, the reference signal identifier may be, for example, a CSI-RS resource identifier or an SSB number.

[0068] For ease of understanding, an example of using TCI status for beam indication is given below.

[0069] As mentioned above, PDCCH and PDSCH can use their own beams independently. Therefore, there may be differences in the beam indication of PDCCH and PDSCH. The beam indication processes of PDCCH and PDSCH are respectively introduced as examples below.

[0070] Referring to Figure 5, for PDCCH, the communication system (e.g., NR system) can use radio resource control (RRC) signaling + medium access control control element (MAC CE) signaling to indicate the TCI state. Specifically, the network side can configure N TCI states for a control resource set (CORESET) through RRC signaling. If N=1, the configured TCI state is used to indicate the reception of PDCCH; if N>1, the network side needs to further activate one of the TCI states through MAC CE signaling, and the activated TCI state is used to indicate the reception of PDCCH.

[0071] As shown in Figure 6, for PDSCH, the communication system can use RRC signaling + MAC CE signaling + DCI indication to indicate the TCI state. Specifically, the network can configure a set of TCI states through RRC signaling; further, the network can select and activate K TCI states (K≤8) from this set of TCI states through MAC CE signaling. Subsequently, when the network schedules the PDSCH via PDCCH, it can use DCI signaling to indicate one of the K TCI states currently used for transmission. The TCI state indicated by the DCI signaling is used to indicate PDSCH reception.

[0072] As mentioned above, the current beam management (or beam measurement) mechanism is aimed at the communication between network devices and terminal devices. Therefore, in the sideline communication system, how to perform beam management (or beam measurement) is a problem that needs to be solved.

[0073] In order to solve the above problems, the embodiments of the present application provide a wireless communication method and communication device. The technical solution of the present application is described in detail below with reference to the accompanying drawings.

[0074] Figure 7 is a flow chart of a wireless communication method provided by an embodiment of the present application. The method shown in Figure 7 is described from the perspective of the interaction between a first device and a second device. The first device may be, for example, the network device 110 or the terminal device 120 shown in Figure 1, and the second device may be, for example, the terminal device 120 shown in Figure 1. The definitions of the first device and the second device may vary depending on different situations, which will be described in detail later. The method shown in Figure 7 may include step S710, which is described below.

[0075] In step S710, the first device sends first configuration information to the second device.

[0076] The first configuration information is associated with measurements of a first sidelink / resource pool, where the first sidelink / resource pool is used for sidelink communication by the second device. In other words, the first configuration information is used by the second device to report measurements in the sidelink, such as measurement reporting of the first sidelink or measurement reporting of the resource pool corresponding to the sidelink communication.

[0077] In this way, the second device can measure the beam associated with the first sidelink / resource pool according to the first configuration information, thereby facilitating beam measurement in the sidelink communication system.

[0078] In some embodiments, both the first device and the second device may be terminal devices. That is, the measurement configuration and measurement reporting between the first device and the second device may be understood as a communication process between the two terminal devices. For example, after the transmitting terminal device sends the first configuration information to the receiving terminal device, the receiving terminal device may measure the first sidelink (or the beam of the first sidelink) and send the measurement result to the transmitting terminal device, so as to manage or adjust the beam for the sidelink data transmission of the two terminal devices, or control the power of the sidelink data transmission of the two terminal devices, etc.

[0079] In some embodiments, when the first device and the second device are both terminal devices, when the first device and the second device perform beam measurement, the measured beam and / or reference signal can be controlled by the first device (for example, a transmitting terminal device). Of course, the measured beam and / or reference signal can also be controlled by the second device (for example, a receiving terminal device). This embodiment of the present application does not limit this.

[0080] In some embodiments, the first device may be a network device, and the second device may be a terminal device. That is, the measurement configuration and measurement reporting between the first device and the second device can be understood as a communication process between the network device and the terminal device. For example, after the network device sends the first configuration information to the terminal device, the terminal device may measure the first sidelink or resource pool and send the measurement results to the network device, so that the network device can better configure sidelink communication resources for the terminal device or adjust the configuration of the relay link for the terminal device.

[0081] In some embodiments, when the first device is a network device and the second device is a terminal device, the terminal device can communicate directly with the network device, for example, when the terminal device is within the coverage area of ​​the network device. This scenario can be understood as communication in a non-relay scenario. In some embodiments, when the first device is a network device and the second device is a terminal device, the terminal device needs to communicate with the network device through a relay terminal. For example, when the terminal device is outside the coverage area of ​​the network device, this scenario can be understood as communication in a relay scenario.

[0082] In some embodiments, the first configuration information may be used to request the second device to perform layer 1 measurements on the first sidelink / resource pool. In some embodiments, the first configuration information may also be used to request the second device to perform layer 3 measurements on the first sidelink / resource pool. Whether layer 1 measurements or layer 3 measurements are performed may be determined based on actual circumstances and is not limited in this embodiment of the present application.

[0083] In some embodiments, the sidelink (e.g., the first sidelink) in the embodiments of the present application may be a PC5 link, or in other words, the terminal devices may communicate via a PC5 link (or PC5 interface). In some embodiments, the network device and the terminal device in the embodiments of the present application may communicate via a Uu interface.

[0084] In some embodiments, after receiving the first configuration information sent by the first device, the second device may perform corresponding measurements based on the first configuration information and report the measurements. It should be understood that the process of performing measurement configuration and measurement reporting between the first device and the second device can be understood as a beam measurement or beam management process.

[0085] For ease of understanding, the beam measurement process in different situations is specifically introduced below in conjunction with embodiments.

[0086] Example 1: Sidelink reporting, layer 1 measurement

[0087] In the first embodiment, the first device and the second device are both terminal devices, and the first device and the second device can perform measurement configuration and measurement reporting through a PC5 link.

[0088] FIG8 is a flow chart of a wireless communication method according to another embodiment of the present application. The method shown in FIG8 may include steps S810 to S830.

[0089] In step S810, the first device sends first configuration information to the second device.

[0090] The first configuration information can be used to instruct the second device to measure one or more beams corresponding to the first sidelink.

[0091] In some embodiments, the first configuration information may be carried in one or more of the following: RRC signaling, MAC CE signaling, and sidelink control information (SCI). In other words, the first configuration information may be sent via RRC signaling / MAC CE signaling / SCI.

[0092] In some embodiments, the first configuration information may include one or more of the following information: the type of measurement signal; beam indication information corresponding to the reference signal; identification of one or more beams corresponding to the first side link; measurement metric corresponding to the measurement signal; the number of beams that the second device needs to report; and the measurement threshold of the beam that the second device needs to report / threshold for triggering the second device to report the measurement.

[0093] The embodiments of the present application do not specifically limit the type of measurement signal. For example, the measurement signal may be one or more of the following measurement signals: SSB, CSI-RS, demodulation reference symbol (DMRS) discovery message, SCI, physical sidelink control channel (PSCCH), physical sidelink shared channel (PSSCH), and physical sidelink feedback channel (PSFCH).

[0094] In some embodiments, the beam indication information corresponding to the reference signal can be used to indicate relevant information of the beam receiving the reference signal. In an embodiment of the present application, the beam indication information corresponding to the reference signal may include multiple types. For example, the beam indication information corresponding to the reference signal may include the TCI state of the reference signal, spatial relationship (spatial-relation), spatial filter, analog phase parameters, etc., which are not limited in this embodiment of the present application. As an implementation method, the beam indication information of the reference signal can be jointly indicated by the TCI state and QCL concept. For example, the beam indication information of the reference signal may include: TCI state ID, QCL type, and type of reference signal.

[0095] In some embodiments, the identifiers of one or more beams corresponding to the first sidelink can be understood as the identifiers of the beams to be measured.

[0096] The embodiments of the present application do not specifically limit the measurement metric corresponding to the measurement signal. For example, the measurement metric corresponding to the measurement signal may be one or more of the following measurement metrics: RSRP, reference signal receiving quality (RSRQ), and SINR. In some embodiments, the measurement metric corresponding to the measurement signal may be a measurement metric filtered by layer 1, or may be a measurement metric filtered by layer 3. Exemplarily, the measurement metric corresponding to the measurement signal may be L1-RSRP, L1-RSRQ, L1-SINR, or L3-RSRP, L3-RSRQ, L3-SINR, or any combination of the above measurement metrics.

[0097] In some embodiments, the measurement threshold of the beam that the second device needs to report may include an upper limit value of the measurement threshold, a lower limit value of the measurement threshold, or upper and lower thresholds of the measurement.

[0098] In some embodiments, the first configuration information may be added / modified / released / activated / deactivated.

[0099] In some embodiments, the first configuration information is configured by the first device in one or more of the following ways: configured according to instructions of a network device; autonomously configured; configured according to protocol provisions, configured according to capabilities of the first device and / or the second device, and configured according to auxiliary information of the second device.

[0100] In some embodiments, the first configuration information may be configured by the first device according to the capabilities of the first device and / or the second device. This application does not specifically limit the content of the capability information associated with the first configuration information. For example, it can be configured according to the capabilities such as the number of signals / measurements / beams supported by the first device and / or the second device.

[0101] The embodiments of the present application do not specifically limit the content of the auxiliary information of the second device. For example, the auxiliary information of the second device may include capability information of the second device, such as the number of signals / measurements / beams supported by the second device.

[0102] In some embodiments, after the second device receives the first configuration information sent by the first device, the second device may feed back the configuration result to the first device and / or execute the corresponding configuration.

[0103] In step S820, the second device measures the beam according to the first configuration information.

[0104] In some embodiments, after receiving the first configuration information, the second device may measure the corresponding beam according to the first configuration information and / or the activation indication information.

[0105] In step S830, the second device sends measurement reporting information to the first device.

[0106] The measurement reporting information includes a measurement result of the second device on at least one beam of the one or more beams associated with the first sidelink.

[0107] In some embodiments, the measurement result of at least one beam among the one or more beams includes: an identifier of the at least one beam, and a measurement value corresponding to the at least one beam.

[0108] In some embodiments, the measurement value corresponding to the at least one beam is a layer 1 measurement value, for example, a measurement value of L1-RSRP, a measurement value of L1-RSRQ, a measurement value of L1-SINR, etc.

[0109] In some embodiments, the measurement report information may carry measurement results for K beams, where K is a positive integer ≥ 1. As an implementation, K may be the number of beams configured for the second device that need to be measured and reported. For example, K may be configured by the first device through the first configuration information. As another implementation, K may be determined based on a threshold configured by the first device, such as the number of beams that meet the threshold requirement. As yet another implementation, K may be the number of all beams measured by the second device.

[0110] In some embodiments, the second device may send the measurement reporting information in one or more of the following ways: SCI, and MAC CE signaling.

[0111] In some embodiments, the measurement reporting information may be sent periodically, or may be triggered based on a first event.

[0112] The embodiment of the present application does not limit the sending period of the measurement reporting information. For example, the measurement reporting period of the second device can be configured by the first device (for example, configured through the first configuration information), or can be configured by the network device, or can be specified by the protocol.

[0113] The embodiments of the present application do not specifically limit the first event corresponding to the measurement report. For example, the first event may include one or more of the following: the second device receives the beam-related configuration and receives a request from the first device; the second device receives the beam-related configuration; a period of time after the second device receives the beam-related configuration; the second device receives the beam-related configuration and completes the measurement of one or more beams corresponding to the first side link; the second device receives the beam-related configuration and the measurement result of at least one of the one or more beams corresponding to the first side link meets the threshold for the second device measurement report; and implementation based on the second device.

[0114] The beam-related configurations received by the second device may include multiple types, for example, TCI configuration, beam identification, the number of beams that the second device needs to report, etc., which is not limited in the embodiments of the present application.

[0115] Continuing with FIG8 , in some embodiments, before step S810, the method may further include step S805. In step S805, the network device sends second configuration information to the first device, where the second configuration information is associated with measurement of the first sidelink. For example, the second configuration information may be used to instruct the second device to measure one or more beams corresponding to the first sidelink.

[0116] After receiving the second configuration information sent by the network device, the first device can determine the first configuration information according to the second configuration information.

[0117] In some embodiments, the sending of the second configuration information is based on certain conditions, such as the first device and / or the second device being in a connected state, or the resources for the first device and / or the second device to perform side communication are configured by a network device.

[0118] In some embodiments, the second configuration information may be sent by the network device through one or more of the following ways: pre-configuration information, system message (eg, system information block, master system information block, etc.), and RRC signaling.

[0119] In some embodiments, the second configuration information may include one or more of the following information: the type of measurement signal, beam indication information corresponding to the reference signal, an identifier of the beam to be measured, a measurement metric corresponding to the measurement signal, the number of beams to be reported by the second device, a measurement threshold for the beams to be reported by the second device / a threshold for triggering measurement reporting by the second device, and a reporting period for the second device. The content of the second configuration information is similar to that of the first configuration information. For content not described in detail in the second configuration information, please refer to the previous description of the first configuration information and will not be repeated here.

[0120] In some embodiments, the second configuration information may be added / modified / released / activated / deactivated.

[0121] In some embodiments, the method shown in Figure 8 may also include step S840, in which the first device sends first indication information to the second device, and the first indication information is used to indicate the activated beam and / or beam indication information (for example, TCI status identifier) ​​to the second device.

[0122] In some embodiments, the activated beam is used for the first device to send sidelink data to the second device.

[0123] In some embodiments, the first indication information is determined by the first device according to measurement reporting information sent by the second device.

[0124] In some embodiments, the first indication information may be carried in one or more of the following: MAC CE signaling and SCI. In some embodiments, the first indication information may be sent in different ways for different channels. For example, for PSCCH reception, it may be indicated by a MAC CE; or for PSSCH reception, it may be indicated by a MAC CE+SCI. PSCCH reception and PSSCH reception are similar to PDCCH and PDSCH reception, respectively. Therefore, their reception methods can also refer to the PDSCH and PDSCH reception described above.

[0125] In some embodiments, the first indication information may include one or more beam indication information, where the one or more beam indication information is used to indicate the activated beam to the second device. Taking the first indication information carried by a MAC CE and / or SCI as an example, the MAC CE and / or SCI may include one or more beam indication information (e.g., one or more TCI status) identifiers.

[0126] In some embodiments, the one or more beam indication information included in the first indication information is one or more beam indication information configured by the first device to the second device through RRC signaling, that is, the beam indication information included in the first indication information is one or more beam indication information in the first configuration information.

[0127] In some embodiments, the one or more beam indication information included in the first indication information may include one or more of the following information: one or more codepoints, and one or more status values ​​corresponding to each of the one or more codepoints. Specifically, whether each codepoint corresponds to one or more status values ​​is configurable and is not limited in this embodiment of the present application.

[0128] It should be noted that the first indication information may be sent when the first configuration information includes multiple beam indication information. Taking the first configuration information configured via RRC signaling as an example, if only one beam indication information is configured in the first configuration information, no MAC CE indication is required. Similarly, the SCI is only used when the MAC CE indicates multiple beam indication information.

[0129] Based on this, the second device can measure / receive data on the corresponding beam according to the configuration and / or activation indication information of the first device.

[0130] In some embodiments, the first device may determine whether to adjust the configuration of the transmit beam based on the measurement reporting information. As an implementation, if the first device determines to adjust the configuration of the transmit beam based on the measurement reporting information, the first device may send a beam reconfiguration message to the second device and / or the first device may report the beam adjustment information to the network device.

[0131] In some embodiments, the network device may determine whether to adjust the configuration of the transmit beam based on the measurement reporting information. As an implementation, after step S830, the method shown in FIG8 may further include steps S850 to S870.

[0132] In step S850, the first device sends measurement reporting information to the network device.

[0133] After the first device sends the measurement reporting information to the network device, the network device determines whether to adjust the configuration of the transmission beam, or in other words, the network device determines whether to reconfigure the beam.

[0134] In step S860, if the network device determines to adjust the configuration of the transmit beam, the network device sends a beam reconfiguration message to the first device.

[0135] In step S870, the first device sends the beam reconfiguration message to the second device.

[0136] Example 2: Sidelink reporting, layer 3 measurement (transmitting terminal device controls the measured beam and / or reference signal)

[0137] In the second embodiment, the first device and the second device are both terminal devices, and the first device and the second device can perform measurement configuration and measurement reporting through a PC5 link.

[0138] In the second embodiment, the beam and / or reference signal measured by the second device is determined by the first device.

[0139] FIG9 is a flow chart of a wireless communication method according to another embodiment of the present application. The method shown in FIG9 may include steps S910 to S930.

[0140] In step S910, the first device sends first configuration information to the second device.

[0141] The first configuration information may be used to instruct the second device to measure the first sidelink.

[0142] In some embodiments, the first configuration information may be carried in one or more of the following: RRC signaling, MAC CE signaling, and SCI.

[0143] In some embodiments, the first configuration information may include one or more of the following information: indication information on whether it is necessary to report the measurement results of one or more beams corresponding to the first side link; the type of measurement signal; beam indication information corresponding to the reference signal; the identifier of the beam to be measured; the measurement metric corresponding to the measurement signal; the number of beams to be reported by the second device; the threshold for triggering the measurement reporting of the second device; the reporting period of the second device; and the measurement control threshold.

[0144] The embodiment of the present application does not specifically limit the type of the measurement signal. For example, the measurement signal may be one or more of the following measurement signals: SSB, CSI-RS, DMRS, discovery message, SCI, PSCCH, PSSCH, and PSFCH.

[0145] The beam indication information corresponding to the reference signal may include various information. For example, the beam indication information corresponding to the reference signal may include the TCI state, spatial relationship, spatial filter, analog phase parameters, etc. of the reference signal. This is not limited in the embodiments of the present application. As an implementation, the beam indication information of the reference signal may be jointly indicated using the TCI state and QCL concepts. For example, the beam indication information of the reference signal may include: TCI state ID, QCL type, and reference signal type.

[0146] The embodiments of the present application do not specifically limit the measurement metric corresponding to the measurement signal. For example, the measurement metric corresponding to the measurement signal may be one or more of the following measurement metrics: RSRP, RSRQ, and SINR. In some embodiments, the measurement metric corresponding to the measurement signal may be a measurement metric filtered through layer 1 or layer 3.

[0147] In some embodiments, the measurement control threshold in the first configuration information may be a layer 1 measurement control threshold.

[0148] In some embodiments, the first configuration information may be added / modified / released / activated / deactivated.

[0149] In some embodiments, the first configuration information is configured by the first device in one or more of the following ways: configured according to instructions of a network device; autonomously configured; configured according to protocol provisions, configured according to capabilities of the first device and / or the second device, and configured according to auxiliary information of the second device.

[0150] In some embodiments, the first configuration information may be configured by the first device according to the capabilities of the first device and / or the second device. This application does not specifically limit the content of the capability information associated with the first configuration information. For example, it can be configured according to the capabilities such as the number of signals / measurements / beams supported by the first device and / or the second device.

[0151] The embodiments of the present application do not specifically limit the content of the auxiliary information of the second device. For example, the auxiliary information of the second device may include capability information of the second device, such as the number of signals / measurements / beams supported by the second device; or, the auxiliary information of the second device may also include the beams and reference signals that the second device wants to measure.

[0152] In some embodiments, after the second device receives the first configuration information sent by the first device, the second device may feed back the configuration result to the first device and / or execute the corresponding configuration.

[0153] In step S920, the second device measures the first sidelink according to the first configuration information.

[0154] In some embodiments, after receiving the first configuration information, the second device may perform measurement according to the first configuration information and obtain a measurement result after layer 3 filtering.

[0155] In step S930, the second device sends measurement reporting information to the first device.

[0156] The measurement reporting information includes the measurement results of the second device on the first side link and / or the measurement results of one or more beams corresponding to the first side link. As an implementation method, if the first configuration information indicates that the second device needs to report the measurement results of one or more beams corresponding to the first side link, the measurement reporting information may include the measurement results of the first side link and the measurement results of one or more beams corresponding to the first side link. As another implementation method, if the first configuration information does not indicate or indicates that the second device does not need to report the measurement results of one or more beams corresponding to the first side link, the measurement reporting information may only include the measurement results of the first side link.

[0157] In some embodiments, the measurement result of the first side link is obtained based on the measurement results of one or more beams corresponding to the first side link. For example, the measurement result of the first side link can be a maximum measurement value / minimum measurement value / average measurement value / any value corresponding to the one or more beams corresponding to the first side link.

[0158] As an example, if the maximum measurement value in one or more beams corresponding to the first side link is less than the first measurement control threshold, the second device may use the maximum measurement value as the measurement result of the first side link; otherwise, the second device may use the average measurement value of the one or more beams as the measurement result of the first side link.

[0159] As another example, if the minimum measurement value in one or more beams corresponding to the first side link is greater than the second measurement control threshold, the second device may use the minimum measurement value as the measurement result of the first side link, otherwise the second device may use the average measurement value of the one or more beams as the measurement result of the first side link.

[0160] In some embodiments, the values ​​of the first measurement control threshold and the second measurement control threshold may be the same or different, which is not limited in this embodiment of the present application.

[0161] In some embodiments, the measurement reporting information may be sent by the second device to the first device via PC5-RRC signaling.

[0162] In some embodiments, the measurement results of the first sidelink and / or the measurement results of one or more beams corresponding to the first sidelink may include: identifications of the one or more beams, and measurement values ​​corresponding to the one or more beams.

[0163] In some embodiments, the measurement value corresponding to the first side link and / or the measurement value corresponding to one or more beams corresponding to the first side link are measurement values ​​filtered by layer 3, for example, the measurement value of L3-RSRP, the measurement value of L3-RSRQ, the measurement value of L3-SINR, etc.

[0164] In some embodiments, the measurement report information may carry the measurement results of the first sidelink and / or K beams, where K is a positive integer ≥ 1. As an implementation method, K may be the number of beams that need to be measured and reported configured for the second device, for example, K may be configured by the first device through the first configuration information. As another implementation method, K may be determined based on the threshold configured by the first device for triggering the measurement report of the second device, such as the number of beams that meet the threshold requirement. As yet another implementation method, K may be the number of all beams measured by the second device.

[0165] In some embodiments, the measurement reporting information may be sent periodically, or may be triggered based on a second event.

[0166] The embodiment of the present application does not limit the sending period of the measurement reporting information. For example, the measurement reporting period of the second device can be configured by the first device (for example, configured through the first configuration information), or can be configured by the network device, or can be specified by the protocol.

[0167] The embodiments of the present application do not specifically limit the second event corresponding to the measurement report. For example, the second event may include one or more of the following: the measurement result of the first sidelink is greater than the first threshold and / or less than the second threshold; the measurement result of at least one of the one or more beams corresponding to the first sidelink is greater than the third threshold and / or less than the fourth threshold; and the second device receives a request from the first device.

[0168] In some embodiments, the values ​​of the first threshold and the second threshold may be the same or different. Similarly, the values ​​of the third threshold and the fourth threshold may be the same or different.

[0169] In some embodiments, if the second device needs to report the measurement results of one or more beams corresponding to the first side link, for each beam, the third threshold and the fourth threshold can be configured separately for each beam; or all beams can also be configured with the same third threshold and fourth threshold.

[0170] In some embodiments, the value of the third threshold may be the same as the first threshold, and the value of the fourth threshold may be the same as the second threshold. Of course, they may also take different values, which is not limited in the embodiments of the present application.

[0171] Continuing with FIG9 , in some embodiments, if the first configuration information is configured by the first device based on instructions from the network device, the method may further include step S905 before step S910. In step S905, the network device sends second configuration information to the first device, where the second configuration information is associated with measurement of the first sidelink. For example, the second configuration information may be used to instruct the second device to measure the first sidelink.

[0172] After receiving the second configuration information sent by the network device, the first device can determine the first configuration information according to the second configuration information.

[0173] In some embodiments, the sending of the second configuration information is based on certain conditions, such as the first device and / or the second device being in a connected state, or the resources for the first device and / or the second device to perform side communication are configured by a network device.

[0174] In some embodiments, the second configuration information may be sent by the network device through one or more of the following ways: pre-configuration information, system message (eg, system information block, master system information block, etc.), and RRC signaling.

[0175] In some embodiments, the second configuration information may include one or more of the following information: the type of the measurement signal, beam indication information corresponding to the reference signal, an identifier of the beam to be measured, a measurement metric corresponding to the measurement signal, the number of beams to be reported by the second device, and a threshold for triggering measurement reporting by the second device. The content of the second configuration information is similar to that of the first configuration information. For content not described in detail in the second configuration information, please refer to the previous description of the first configuration information and will not be repeated here.

[0176] In some embodiments, the second configuration information may be added / modified / released / activated / deactivated.

[0177] In some embodiments, the first device may control the power of the first sidelink according to the measurement reporting information. As an implementation, the first device may send second indication information to the second device, where the second indication information is used to control (or adjust) the power of the first sidelink.

[0178] In some embodiments, after controlling the power of the first sidelink, the first device may also report the power adjustment status to the network device. As an implementation, the second device may send third indication information to the network device, where the third indication information is used to report the power adjustment status to the network device.

[0179] In some embodiments, the network device may control the power of the second device according to the third indication information.

[0180] Example 3: Sidelink reporting, layer 3 measurement (receiving terminal device controls the measured beam and / or reference signal)

[0181] In the third embodiment, the first device and the second device are both terminal devices, and the first device and the second device can perform measurement configuration and measurement reporting through a PC5 link.

[0182] In the third embodiment, the beam and / or reference signal measured by the second device is determined by the second device.

[0183] Figure 10 is a flow chart of a wireless communication method according to another embodiment of the present application. The method shown in Figure 10 may include steps S1010 to S1040.

[0184] In step S1010, the first device sends first configuration information to the second device.

[0185] The first configuration information may be used to instruct the second device to measure the first sidelink.

[0186] In some embodiments, the first configuration information may be carried in one or more of the following: RRC signaling, MAC CE signaling, and SCI.

[0187] In some embodiments, the first configuration information may include one or more of the following information: indication information on whether it is necessary to report the measurement results of one or more beams corresponding to the first side link; the type of measurement / transmission signal supported by the first device; beam indication information corresponding to the reference signal; the identifier of the transmission / measured beam; the measurement metric corresponding to the measurement signal; the number of beams to be reported by the second device; the threshold for triggering the measurement report of the second device; the reporting period of the second device; and the measurement control threshold.

[0188] The embodiment of the present application does not specifically limit the type of measurement / transmission signal supported by the first device. For example, the measurement / transmission signal supported by the first device may be one or more of the following signals: SSB, CSI-RS, DMRS, discovery message, SCI, PSCCH, PSSCH, and PSFCH.

[0189] The beam indication information corresponding to the reference signal may include various information. For example, the beam indication information corresponding to the reference signal may include the TCI state, spatial relationship, spatial filter, analog phase parameters, etc. of the reference signal. This is not limited in the embodiments of the present application. As an implementation, the beam indication information of the reference signal may be jointly indicated using the TCI state and QCL concepts. For example, the beam indication information of the reference signal may include: TCI state ID, QCL type, and reference signal type.

[0190] The embodiments of the present application do not specifically limit the measurement metric corresponding to the measurement signal. For example, the measurement metric corresponding to the measurement signal may be one or more of the following measurement metrics: RSRP, RSRQ, and SINR. In some embodiments, the measurement metric corresponding to the measurement signal may be a measurement metric filtered through layer 1 or layer 3.

[0191] In some embodiments, the measurement control threshold in the first configuration information may be a layer 1 measurement control threshold.

[0192] In some embodiments, the first configuration information may be added / modified / released / activated / deactivated.

[0193] In some embodiments, the first configuration information is configured by the first device in one or more of the following ways: configured according to instructions of a network device; autonomously configured; configured according to protocol provisions, configured according to capabilities of the first device and / or the second device, and configured according to auxiliary information of the second device.

[0194] In some embodiments, the first configuration information may be configured by the first device according to the capabilities of the first device and / or the second device. This application does not specifically limit the content of the capability information associated with the first configuration information. For example, it can be configured according to the capabilities such as the number of signals / measurements / beams supported by the first device and / or the second device.

[0195] The embodiments of the present application do not specifically limit the content of the auxiliary information of the second device. For example, the auxiliary information of the second device may include capability information of the second device, such as the number of signals / measurements / beams supported by the second device; or, the auxiliary information of the second device may also include the beams and reference signals that the second device wants to measure.

[0196] In some embodiments, after the second device receives the first configuration information sent by the first device, the second device may feed back the configuration result to the first device and / or execute the corresponding configuration.

[0197] In step S1020, the second device sends fourth indication information to the first device. The fourth indication information is used to indicate one or more of the following information to the first device: an activated signal to be measured, a beam to be measured, and beam indication information of the beam to be measured.

[0198] In some embodiments, the fourth indication information may be carried in one or more of the following: MAC CE signaling, and SCI.

[0199] In some embodiments, the fourth indication information may include a beam identifier, for example, the beam identifier may be included in MAC CE signaling or SCI signaling.

[0200] In some embodiments, the fourth indication information may include indication information of a reference signal type. For example, indication information of a different reference signal type may be included for each beam.

[0201] In some embodiments, the fourth indication information may include one or more beam indication information, and the one or more beam indication information may be used to indicate the activated beam to the first device.

[0202] In some embodiments, the one or more beam indication information may include one or more of the following: one or more code points, and one or more state values ​​corresponding to each of the one or more code points. Specifically, whether each code point corresponds to one state value or multiple state values ​​is configurable and is not limited in this embodiment of the present application.

[0203] In some embodiments, the fourth indication information may be determined by the second device based on an indication / configuration of the network device. That is, after receiving the first configuration information sent by the first device, the second device may report the first configuration information to the network device and receive the fourth indication information sent by the network device, so as to transmit the fourth indication information to the first device, indicating information such as the activated beam to the first device.

[0204] It should be noted that the fourth indication information can be sent when the first configuration information includes multiple beam indication information. Taking the first configuration information configured via RRC signaling as an example, if only one beam indication information is configured in the first configuration information, no MAC CE indication is required. Similarly, the SCI is only used when the MAC CE indicates multiple beam indication information.

[0205] In some embodiments, after step S1020, the method may further include step S1025, in which the first device sends feedback information of the fourth indication information to the second device, where the feedback information is used to indicate whether the first device accepts the indication / configuration corresponding to the fourth indication information.

[0206] In step S1030, the second device measures the first sidelink according to the first configuration information.

[0207] In some embodiments, after receiving the first configuration information, the second device may perform measurement according to the first configuration information and / or feedback information sent by the first device, and obtain a measurement result after layer 3 filtering.

[0208] In step S1040, the second device sends measurement reporting information to the first device.

[0209] The measurement reporting information includes the measurement results of the second device on the first side link and / or the measurement results of one or more beams corresponding to the first side link. As an implementation method, if the first configuration information indicates that the second device needs to report the measurement results of one or more beams corresponding to the first side link, the measurement reporting information may include the measurement results of the first side link and the measurement results of one or more beams corresponding to the first side link. As another implementation method, if the first configuration information does not indicate or indicates that the second device does not need to report the measurement results of one or more beams corresponding to the first side link, the measurement reporting information may only include the measurement results of the first side link.

[0210] In some embodiments, the measurement result of the first side link is obtained based on the measurement results of one or more beams corresponding to the first side link. For example, the measurement result of the first side link can be a maximum measurement value / minimum measurement value / average measurement value / any value corresponding to the one or more beams corresponding to the first side link.

[0211] In some embodiments, how the measurement result of the first side link is determined can refer to the configuration of the measurement control threshold in the first configuration information. As an example, if the maximum measurement value in one or more beams corresponding to the first side link is less than the first measurement control threshold, the second device can use the maximum measurement value as the measurement result of the first side link, otherwise the second device can use the average measurement value of the one or more beams as the measurement result of the first side link. As another example, if the minimum measurement value in one or more beams corresponding to the first side link is greater than the second measurement control threshold, the second device can use the minimum measurement value as the measurement result of the first side link, otherwise the second device can use the average measurement value of the one or more beams as the measurement result of the first side link.

[0212] In some embodiments, the first measurement control threshold and the second measurement control threshold may have the same value. In some embodiments, the first measurement control threshold and the second measurement control threshold may have different values, which is not limited in the embodiments of the present application.

[0213] In some embodiments, the measurement reporting information may be sent by the second device to the first device via PC5-RRC signaling.

[0214] In some embodiments, the measurement results of the first sidelink and / or the measurement results of one or more beams corresponding to the first sidelink may include: identifications of the one or more beams, and measurement values ​​corresponding to the one or more beams.

[0215] In some embodiments, the measurement value corresponding to the first side link and / or the measurement value corresponding to one or more beams corresponding to the first side link are measurement values ​​filtered by layer 3, for example, the measurement value of L3-RSRP, the measurement value of L3-RSRQ, the measurement value of L3-SINR, etc.

[0216] In some embodiments, the measurement report information may carry the measurement results of the first sidelink and / or K beams, where K is a positive integer ≥ 1. As an implementation method, K may be the number of beams that need to be measured and reported configured for the second device, for example, K may be configured by the first device through the first configuration information. As another implementation method, K may be determined based on the threshold configured by the first device for triggering the measurement report of the second device, such as the number of beams that meet the threshold requirement. As yet another implementation method, K may be the number of all beams measured by the second device.

[0217] In some embodiments, the measurement reporting information may be sent periodically, or may be triggered based on a second event.

[0218] The embodiment of the present application does not limit the sending period of the measurement reporting information. For example, the measurement reporting period of the second device can be configured by the first device (for example, configured through the first configuration information), or can be configured by the network device, or can be specified by the protocol.

[0219] The embodiments of the present application do not specifically limit the second event corresponding to the measurement report. For example, the second event may include one or more of the following: the measurement result of the first sidelink is greater than the first threshold and / or less than the second threshold; the measurement result of at least one of the one or more beams corresponding to the first sidelink is greater than the third threshold and / or less than the fourth threshold; and the second device receives a request from the first device.

[0220] In some embodiments, the values ​​of the first threshold and the second threshold may be the same or different. Similarly, the values ​​of the third threshold and the fourth threshold may be the same or different.

[0221] In some embodiments, if the second device needs to report the measurement results of one or more beams corresponding to the first side link, for each beam, the third threshold and the fourth threshold can be configured separately for each beam; or all beams can also be configured with the same third threshold and fourth threshold.

[0222] In some embodiments, the value of the third threshold may be the same as the first threshold, and the value of the fourth threshold may be the same as the second threshold. Of course, they may also take different values, which is not limited in the embodiments of the present application.

[0223] In some embodiments, step S1040 may be combined with the aforementioned step S1020. That is, the second device may simultaneously send indication information including the measurement result of the measured beam and the reference signal used for the measurement beam.

[0224] Continuing with FIG10 , in some embodiments, if the first configuration information is configured by the first device based on instructions from the network device, the method may further include step S1005 before step S1010. In step S1005, the network device transmits second configuration information to the first device, where the second configuration information is associated with a measurement or signal transmission configuration for the first sidelink. For example, the second configuration information may be used to instruct the second device to measure the first sidelink, or to instruct the first device to transmit a related signal configuration.

[0225] After receiving the second configuration information sent by the network device, the first device can determine the first configuration information according to the second configuration information.

[0226] In some embodiments, the sending of the second configuration information is based on certain conditions, such as the first device and / or the second device being in a connected state, or the resources for the first device and / or the second device to perform side communication are configured by a network device.

[0227] In some embodiments, the second configuration information may be sent by the network device through one or more of the following ways: pre-configuration information, system message (eg, system information block, master system information block, etc.), and RRC signaling.

[0228] In some embodiments, the second configuration information may include one or more of the following information: the type of the measurement / transmitted signal, beam indication information corresponding to the reference signal, an identifier of the transmitted / measured beam, a measurement metric corresponding to the measurement signal, the number of beams to be reported by the second device, and a threshold for triggering measurement reporting by the second device. The content of the second configuration information is similar to that of the first configuration information. For content not described in detail in the second configuration information, please refer to the previous description of the first configuration information and will not be repeated here.

[0229] In some embodiments, the second configuration information may be added / modified / released / activated / deactivated.

[0230] In some embodiments, the first device may control the power of the first sidelink according to the measurement reporting information. As an implementation, the first device may send second indication information to the second device, where the second indication information is used to control (or adjust) the power of the first sidelink.

[0231] In some embodiments, after controlling the power of the first sidelink, the first device may also report the power adjustment status to the network device. As an implementation, the second device may send third indication information to the network device, where the third indication information is used to report the power adjustment status to the network device.

[0232] In some embodiments, the network device may control the power of the second device according to the third indication information.

[0233] Example 4: Terminal device reports to network device, layer 3 measurement (non-relay scenario)

[0234] In the fourth embodiment, the first device is a network device, the second device is a terminal device, and the first device and the second device can perform measurement configuration and measurement reporting through a Uu interface.

[0235] Figure 11 is a flow chart of a wireless communication method according to another embodiment of the present application. The method shown in Figure 11 may include steps S1110 to S1130.

[0236] In step S1110 , the first device sends first configuration information to the second device.

[0237] The first configuration information may be used to instruct the second device to measure the resource pool.

[0238] In some embodiments, the first configuration information may be carried in one or more of the following: a pre-configuration message, a system message (eg, a system information block), and RRC signaling.

[0239] In some embodiments, the first configuration information may include one or more of the following information: the resource pool for measurement; the identifier of the beam to be measured; an indication of whether it is necessary to measure / report the measurement results of one or more beams in the resource pool; the threshold for triggering the measurement report of the second device; and the reporting period of the second device.

[0240] In some embodiments, the first configuration information may be added / modified / released / activated / deactivated.

[0241] In some embodiments, after the second device receives the first configuration information sent by the first device, the second device may feed back the configuration result to the first device and / or execute the corresponding configuration.

[0242] In step S1120, the second device measures the resource pool according to the first configuration information.

[0243] In some embodiments, after receiving the first configuration information, the second device may perform measurement according to the first configuration information and obtain a measurement result after layer 3 filtering.

[0244] In step S1130, the second device sends measurement reporting information to the first device.

[0245] The measurement reporting information includes the measurement results of the resource pool and / or the measurement results of one or more beams in the resource pool by the second device. As an implementation method, if the first configuration information indicates that the second device needs to report the measurement results of one or more beams in the resource pool, the measurement reporting information may include the measurement results of the resource pool and the measurement results of one or more beams in the resource pool. As another implementation method, if the first configuration information does not indicate or indicates that the second device does not need to report the measurement results of one or more beams in the resource pool, the measurement reporting information may only include the measurement results of the resource pool.

[0246] In some embodiments, the measurement result of the resource pool is obtained based on the measurement results of one or more beams in the resource pool. For example, the measurement result of the resource pool may be the maximum measurement value, minimum measurement value, or common statistical value corresponding to one or more beams in the resource pool. In some embodiments, the common statistical value corresponding to the one or more beams can be understood as a statistical value obtained by measuring the resources within the measurement window without distinguishing between beams within the measurement window.

[0247] In some embodiments, the measurement reporting information may be sent by the second device to the first device via RRC signaling.

[0248] In some embodiments, the measurement result of the resource pool and / or the measurement result of one or more beams in the resource pool may include: identifications of the one or more beams, and measurement values ​​corresponding to the one or more beams.

[0249] In some embodiments, the measurement value corresponding to the resource pool and / or the measurement value corresponding to one or more beams in the resource pool are layer 3 filtered measurement values, for example, L3-RSRP measurement value, L3-RSRQ measurement value, L3-SINR measurement value, etc.

[0250] In some embodiments, the measurement result of the resource pool and / or the measurement result of one or more beams in the resource pool is a channel busy ratio (CBR) result.

[0251] In some embodiments, the measurement report information may carry measurement results of the resource pool and / or K beams, where K is a positive integer ≥ 1. As an implementation method, K may be the number of beams that need to be measured and reported configured for the second device, for example, K may be configured by the first device through the first configuration information. As another implementation method, K may be determined based on the threshold configured by the first device for triggering the measurement report of the second device, such as the number of beams that meet the threshold requirement. As yet another implementation method, K may be the number of all beams measured by the second device.

[0252] In some embodiments, the measurement reporting information may be sent periodically, or may be triggered based on a third event.

[0253] The embodiment of the present application does not limit the sending period of the measurement reporting information. For example, the period of the measurement reporting of the second device may be configured by the network device.

[0254] The embodiments of the present application do not specifically limit the third event corresponding to the measurement report. For example, the third event may include one or more of the following: a measurement result of the resource pool is greater than a fifth threshold and / or less than a sixth threshold; a measurement result of at least one of one or more beams in the resource pool is greater than a seventh threshold and / or less than an eighth threshold; and the second device receives request information from the first device.

[0255] In some embodiments, the values ​​of the fifth threshold and the sixth threshold may be the same or different. Similarly, the values ​​of the seventh threshold and the eighth threshold may be the same or different.

[0256] In some embodiments, if the second device needs to report the measurement results of one or more beams in the resource pool, for each beam, the seventh threshold and the eighth threshold can be configured separately for each beam; or all beams can also be configured with the same seventh threshold and eighth threshold.

[0257] In some embodiments, the value of the seventh threshold may be the same as the fifth threshold, and the value of the eighth threshold may be the same as the sixth threshold. Of course, they may also take different values, which is not limited in the embodiments of the present application.

[0258] Example 5: Terminal device reports to network device, layer 3 measurement (relay scenario)

[0259] In Example 5, the first device is a network device and / or a relay terminal, and the second device is a remote terminal. The first and second devices can perform measurement configuration and measurement reporting via the Uu interface and / or the PC5 interface. In other words, the technical solution of Example 5 can be applied to scenarios where the second device accesses the network via an indirect connection, that is, where the second device accesses the network via a relay terminal.

[0260] Figure 12 is a flow chart of a wireless communication method according to another embodiment of the present application. The method shown in Figure 12 may include steps S1210 to S1230.

[0261] In step S1210, the first device sends first configuration information to the second device.

[0262] The first configuration information may be used to instruct the second device to measure one or more relay links managed by the second device.

[0263] In some embodiments, if the first device is a network device, the first configuration information may be carried in one or more of the following: a pre-configuration message, a system message (e.g., a system information block), or RRC signaling. In some embodiments, if the first device is a relay terminal, the first configuration information may be carried in one or more of the following: RRC signaling, MAC CE signaling, and SCI.

[0264] In some embodiments, the first configuration information may include one or more of the following information: the type of measurement signal; beam indication information corresponding to the reference signal; the identifier of the beam to be measured; the measurement metric corresponding to the measurement signal; the number of beams to be reported by the second device; indication information on whether the measurement results of one or more beams corresponding to the relay link need to be reported; the threshold for triggering the measurement report of the second device; and the measurement control threshold.

[0265] The embodiment of the present application does not specifically limit the type of the measurement signal. For example, the measurement signal may be one or more of the following measurement signals: SSB, CSI-RS, DMRS, discovery message, SCI, PSCCH, PSSCH, and PSFCH.

[0266] The beam indication information corresponding to the reference signal may include various information. For example, the beam indication information corresponding to the reference signal may include the TCI state, spatial relationship, spatial filter, analog phase parameters, etc. of the reference signal. This is not limited in the embodiments of the present application. As an implementation, the beam indication information of the reference signal may be jointly indicated using the TCI state and QCL concepts. For example, the beam indication information of the reference signal may include: TCI state ID, QCL type, and reference signal type.

[0267] The embodiments of the present application do not specifically limit the measurement metric corresponding to the measurement signal. For example, the measurement metric corresponding to the measurement signal may be one or more of the following measurement metrics: RSRP, RSRQ, and SINR. In some embodiments, the measurement metric corresponding to the measurement signal may be a measurement metric filtered through layer 1 or layer 3.

[0268] In some embodiments, the measurement control threshold in the first configuration information may be a layer 1 measurement control threshold.

[0269] In some embodiments, the first configuration information may be entirely configured by the network device to the second device. As an implementation, the first configuration information may be sent by the network device to the second device via a relay terminal device.

[0270] In some embodiments, the first configuration information may be configured entirely by the relay terminal to the second device. As an implementation, the first configuration information may be configured autonomously by the relay terminal to the second device.

[0271] In some embodiments, part of the information in the first configuration information may be configured by the network device to the second device, and part of the information may be configured by the relay terminal to the second device. For example, one or more of the information including the measurement metric corresponding to the measurement signal, the number of beams to be reported by the second device, indication information indicating whether the measurement results of one or more beams corresponding to the relay link need to be reported, the threshold for triggering the second device to report the measurement, and the measurement control threshold may be configured by the network device, while one or more of the information including the type of the measurement signal, the beam indication information corresponding to the reference signal, and the identifier of the beam to be measured may be configured by the relay terminal.

[0272] In some embodiments, when part or all of the information in the first configuration information is configured by the relay terminal, the first configuration information may be configured by the relay terminal in one or more of the following ways: configured according to instructions of the network device; autonomously configured; configured according to protocol provisions, configured according to the capabilities of the relay terminal and / or the second device, and configured according to auxiliary information of the second device.

[0273] In some embodiments, the first configuration information may be added / modified / released / activated / deactivated.

[0274] In some embodiments, after the second device receives the first configuration information sent by the first device, the second device may feed back the configuration result to the first device and / or execute the corresponding configuration.

[0275] In step S1220, the second device measures one or more relay links associated with the second device according to the first configuration information.

[0276] In some embodiments, after receiving the first configuration information, the second device may perform measurement according to the first configuration information and / or the activation indication information, and obtain a measurement result after layer 3 filtering.

[0277] In step S1230, the second device sends measurement reporting information to the first device.

[0278] The measurement reporting information includes the measurement results of the second device on one or more relay links associated with the second device and / or the measurement results of one or more beams corresponding to each of the one or more relay links. As an implementation method, if the first configuration information indicates that the second device needs to report the measurement results of one or more beams corresponding to the relay link, the measurement reporting information may include the measurement results of one or more relay links associated with the second device and the measurement results of one or more beams corresponding to each of the one or more relay links. As another implementation method, if the first configuration information does not indicate or indicates that the second device does not need to report the measurement results of one or more beams corresponding to the relay link, the measurement reporting information may only include the measurement results of one or more relay links associated with the second device.

[0279] In some embodiments, the measurement results of one or more relay links associated with the second device may include the measurement results of the relay link corresponding to the serving relay terminal and / or the measurement results of the relay link corresponding to the candidate relay terminal. In other words, in addition to measuring the measurement results corresponding to the serving relay link, the second device also needs to measure the discovery-based measurement values ​​of other candidate relay terminals.

[0280] In some embodiments, the measurement result of the first relay link may be obtained based on the measurement results of one or more beams corresponding to the first relay link, where the first relay link may be any one of the one or more relay links associated with the second device. For example, the measurement result of the first relay link may be a maximum measurement value, a minimum measurement value, an average measurement value, or an arbitrary value corresponding to the one or more beams corresponding to the first relay link.

[0281] In some embodiments, how the measurement result of the first relay link is determined can refer to the configuration of the measurement control threshold in the first configuration information. As an example, if the maximum measurement value in one or more beams corresponding to the first relay link is less than the first measurement control threshold, the second device can use the maximum measurement value as the measurement result of the first relay link, otherwise the second device can use the average measurement value of the one or more beams as the measurement result of the first relay link. As another example, if the minimum measurement value in one or more beams corresponding to the first relay link is greater than the second measurement control threshold, the second device can use the minimum measurement value as the measurement result of the first relay link, otherwise the second device can use the average measurement value of the one or more beams as the measurement result of the first relay link.

[0282] In some embodiments, the measurement reporting information may be sent by the second device to the first device via RRC signaling.

[0283] In some embodiments, if the first device is a network device, the measurement reporting information may be sent to the network device.

[0284] In some embodiments, if the first device is a relay terminal, the measurement reporting information may be sent to the relay terminal.

[0285] In some embodiments, if the first device includes a network device and a relay terminal, the measurement reporting information may be sent only to the network device. However, embodiments of the present application are not limited thereto. For example, if the first device includes a network device and a relay terminal, the measurement reporting information may be sent to both the network device and the relay terminal.

[0286] In some embodiments, the measurement results of one or more relay links associated with the second device may include: an identifier of the relay terminal corresponding to the one or more relay links, an identifier of the beam corresponding to the one or more relay links, and a measurement value of the beam corresponding to the one or more relay links.

[0287] In some embodiments, the identifier of the relay terminal corresponding to the one or more relay links may be a layer 2 identifier (relay UE L2ID) of the relay terminal.

[0288] In some embodiments, the measurement values ​​corresponding to one or more relay links associated with the second device and / or the measurement values ​​corresponding to one or more beams corresponding to each of the one or more relay links are layer 3 filtered measurement values, for example, L3-RSRP measurement values, L3-RSRQ measurement values, L3-SINR measurement values, etc.

[0289] In some embodiments, the measurement reporting information may carry the measurement results of one or more relay links and / or the measurement results of K beams measured by the second device, where K is a positive integer ≥ 1. As an implementation method, K may be the number of beams that need to be measured and reported configured for the second device, for example, K may be configured by the first device through the first configuration information. As another implementation method, K may be determined based on the threshold configured by the first device for triggering the measurement report of the second device, such as the number of beams that meet the threshold requirements. As yet another implementation method, K may be the number of all beams measured by the second device.

[0290] In some embodiments, the measurement reporting information may be sent periodically, or may be triggered based on a fourth event.

[0291] The embodiment of the present application does not limit the sending period of the measurement reporting information. For example, the period of the measurement reporting of the second device may be configured by the network device, or may be specified by the protocol.

[0292] The embodiment of the present application does not specifically limit the fourth event corresponding to the measurement report. For example, the fourth event may include one or more of the following: the measurement result of the serving relay terminal is less than the ninth threshold; the measurement result of the relay terminal to be selected is greater than the tenth threshold; the measurement result of the serving cell is less than the eleventh threshold; the measurement result of at least one beam corresponding to the relay link is greater than the twelfth threshold or less than the thirteenth threshold; the second device receives the request information of the first device; and the upper layer indicates that the current serving relay is unavailable / needs to switch paths (such as the current serving relay is unavailable / needs to switch paths due to business needs).

[0293] In some embodiments, the twelfth threshold or the thirteenth threshold corresponding to different beams corresponding to the relay link can be the same or different, and the embodiments of the present application do not limit this. In other words, different beams corresponding to the relay link can use the same threshold value, or threshold values ​​can be set separately for different beams.

[0294] Exemplarily, when the measurement reporting information does not include the measurement results of each beam, the fourth event can be a combination of any two of the events listed above, such as the measurement result of the serving relay terminal is less than the ninth threshold and the measurement result of the relay terminal to be selected is greater than the tenth threshold; or, the measurement result of the relay terminal to be selected is greater than the tenth threshold and the measurement result of the serving cell is less than the eleventh threshold, etc.

[0295] Exemplarily, the fourth event may be that the measurement result of at least one beam corresponding to the relay link is greater than the twelfth threshold or less than the thirteenth threshold, and any combination of other listed events. For example, the fourth event may be that the measurement result of the serving relay terminal is less than the ninth threshold and the measurement result of at least one beam corresponding to the relay link is greater than the twelfth threshold or less than the thirteenth threshold; or, the fourth event may be that the measurement result of the relay terminal to be selected is greater than the tenth threshold, and the measurement result of the serving cell is less than the eleventh threshold, and the measurement result of at least one beam corresponding to the relay link is greater than the twelfth threshold or less than the thirteenth threshold, etc.

[0296] Continuing to refer to Figure 12, in some embodiments, before step S1220, the method shown in Figure 12 may also include step S1215, in which the relay terminal sends fifth indication information to the second device, and the fifth indication information is used to indicate the activated beam and / or beam indication information (for example, TCI status identifier) ​​to the second device.

[0297] In some embodiments, the activated beam is used for the first device to send sidelink data to the second device.

[0298] In some embodiments, the fifth indication information may be carried in one or more of the following: MAC CE signaling and SCI. In some embodiments, the fifth indication information may be sent in different ways for different channels. For example, for PSCCH reception, it may be indicated by MAC CE; or for PSSCH reception, it may be indicated by MAC CE+SCI.

[0299] In some embodiments, the fifth indication information may include one or more beam indication information, where the one or more beam indication information is used to indicate the activated beam to the second device. Taking the fifth indication information carried by a MAC CE and / or SCI as an example, the MAC CE and / or SCI may include one or more beam indication information (e.g., one or more TCI status) identifiers.

[0300] In some embodiments, the one or more beam indication information included in the fifth indication information is one or more of the beam indication information configured by the first device to the second device through RRC signaling, that is, the beam indication information included in the fifth indication information is one or more of the beam indication information in the first configuration information.

[0301] In some embodiments, the one or more beam indication information included in the fifth indication information may include one or more of the following information: one or more codepoints, and one or more status values ​​corresponding to each of the one or more codepoints. Specifically, whether each codepoint corresponds to one or more status values ​​is configurable and is not limited in this embodiment of the present application.

[0302] It should be noted that the fifth indication information may be sent when the first configuration information includes multiple beam indication information. Taking the first configuration information configured via RRC signaling as an example, if only one beam indication information is configured in the first configuration information, no MAC CE indication is required. Similarly, the SCI is only used when the MAC CE indicates multiple beam indication information.

[0303] In some embodiments, the method shown in FIG12 may further include step S1240, in which the first device sends a reconfiguration message to the second device, where the reconfiguration message includes configuration information associated with the mobility of the second device. For example, the reconfiguration message may be used to instruct the second device to switch from the first relay terminal to the second relay terminal, or to instruct the second device to switch from a direct connection to an indirect connection, or to instruct the second device to switch from an indirect connection to a direct connection, or to instruct the second device to switch cells or network devices, etc.

[0304] The method embodiment of the present application is described in detail above in conjunction with Figures 1 to 12. The device embodiment of the present application is described in detail below in conjunction with Figures 13 to 15. It should be understood that the description of the method embodiment corresponds to the description of the device embodiment.
