Description

Communication method, communication device and communication system

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on April 3, 2024, with application number 202410406141.7 and application name “Communication Method, Communication Device and Communication System”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method, a communication device, and a communication system. Background Art

[0003] Currently, channel state information (CSI) reporting related to Layer 1 (L1) measurements can be configured to be aperiodic, such as using the physical downlink control channel (PUSCH); periodic, such as using the physical uplink control channel (PUCCH); or semi-persistent, such as using PUCCH and PUSCH activated by downlink control information (DCI). Typically, L1 CSI reporting is used to detect the serving cell, and the L1 measurement results within the distributed unit (DU) can be carried in the serving cell's CSI report, which contains an additional physical cell identifier (PCI).

[0004] In some current discussions, the measurement reporting of L1 can be extended to the same-frequency or different-frequency cells in the same centralized unit (CU), and the reference signal received power (RSRP) quality of the preset cell and all synchronization signals / physical broadcast channel blocks (synchronization signal and PBCH block, SSB) in the preset cell can be reported through uplink control information (UCI). Since the number of preset cells and the number of SSBs are large, the amount of data to be reported is large, resulting in high complexity of data coding and large signaling overhead for uploading data. Summary of the Invention

[0049] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0050] It should be understood that the terms "first," "second," and the like in the specification, claims, and drawings of this application are used to distinguish between different objects, rather than to describe a particular order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements, but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0051] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0052] Currently, during continuous L1 / L2 triggered mobility switching (LTM) across CUs, the UE user equipment (UE) needs to measure and report L1 measurement reports of different DUs under multiple CUs. The amount of data to be reported is large. The existing method of directly uniformly encoding the SSBs of multiple cells has high coding complexity and large signaling overhead.

[0053] In view of this, the present application proposes a communication method in which a terminal device can receive a first configuration sent by a network device, the first configuration being used to measure M beams; the first configuration being further used to indicate at least one first condition; and first information being sent, the first information including layer 1 measurement information for N beams, each of the N beams satisfying at least one first condition, N being less than or equal to M, and the N beams belonging to the M beams. This method selects the reported layer 1 measurement information for the beam based on the first condition, thereby reducing the amount of transmitted data.

[0054] In order to better understand the communication method, communication device and communication system proposed in this application, the network architecture applied in the embodiments of this application is described below.

[0055] Exemplarily, the communication system may be: a global system for mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) system, a general packet radio service (GPRS), an LTE system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a universal mobile telecommunications system (UMTS) system, an enhanced data rate for GSM evolution (EDGE) system, and a world-wide interoperability for microwave access (WiMAX) system. The technical solutions of the embodiments of the present application can also be applied to other communication systems, such as public land mobile network (PLMN) systems, advanced long term evolution (LTE advanced, LTE-A) systems, fifth generation mobile communication (5G) systems, new radio (NR) systems, machine to machine communication (M2M) systems, or other communication systems evolved in the future, etc., and the embodiments of the present application are not limited to this. The technical solutions provided by the embodiments of the present application can also be applied to other communication systems, in which there are entities that can send control information and send (and / or receive) transmission blocks, and in which there are other entities that can receive control information and receive (and / or send) transmission blocks.

[0056] Please refer to FIG1 , which is a schematic diagram of a network architecture of a communication system provided in an embodiment of the present application.

[0057] As shown in Figure 1, a network device 101 and a terminal device 102 form a communication system. In Figure 1, solid lines with arrows represent communication connections, and dashed lines with arrows represent operations such as measurements.

[0058] In this application, the architecture of the network device 101 can be a CU-DU architecture. CU stands for Centralized Unit (CU), and DU stands for Distributed Unit (DU). For example, in the 5G architecture, the DUs of different base stations are deployed independently, but the CUs of different base stations are deployed centrally. The RRU and antenna are combined into the AAU, while the BBU is split into the DU and CU. Each base station has a set of DUs, and multiple sites share the same CU for centralized management.

[0059] As shown in Figure 1, the network device 101 may include at least one DU (such as a first DU) and at least one CU (such as a first CU). The first DU is the DU where the service cell of the terminal device 102 is located, and the first DU establishes a communication connection with the first CU.

[0060] Exemplarily, the network device 101 includes DUs where the candidate cells of the terminal device 102 are located, such as a second DU and a third DU, wherein the second DU can establish a communication connection with the first CU, and the third DU can establish a communication connection with the second CU.

[0061] The terminal device 102 may be connected to the network device 101 in a wireless manner and may be connected to the core network through the network device 101. The terminal device 102 may be fixed or mobile.

[0062] It should be noted that the first DU, second DU, third DU, first CU and second CU can be separate network devices respectively. In the embodiment of the present application, the five separate network devices of the first DU, second DU, third DU, first CU and second CU are referred to as network devices 101.

[0063] The network device 101 may be an entity for transmitting or receiving signals, or may be a device for communicating with the terminal device 102. The network device may be a base transceiver station (BTS) in a global system for mobile communications (GSM) system or a code division multiple access (CDMA) system, or a base station (NodeB, NB) in a wideband code division multiple access (WCDMA) system, or an evolved NodeB (eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (CRAN) scenario, or the network device may be a relay station, an access point, an in-vehicle device, a wearable device, a network device in a 5G network, or a network device in a future evolved PLMN network, etc., and the embodiments of the present application are not limited thereto. The network device may be a device in a wireless network, such as a radio access network (RAN) node that connects the terminal device 102 to the wireless network. Currently, some examples of RAN nodes include base stations, next-generation base stations (gNBs), transmission reception points (TRPs), evolved Node Bs (eNBs), home base stations, baseband units (BBUs), or access points (APs) in Wi-Fi systems. In one network architecture, network equipment may include centralized unit (CU) nodes, distributed unit (DU) nodes, or RAN equipment including CU nodes and DU nodes. In an O-RAN system, the CU may also be referred to as an O-CU, and the DU may also be referred to as an O-DU.

[0064] Because the embodiments of the present application mainly involve access network devices, in the following text, unless otherwise specified, the network devices mentioned are all access network devices. In the following text, base stations can be used to represent network devices and / or access network devices.

[0065] As an example, the interface between the CU and DU can be called the F1 interface, where the control plane (CP) interface can be F1-C and the user plane (UP) interface can be F1-U. The CU and DU can be divided according to the protocol layers of the wireless network. For example, the functions of the PDCP layer and above are set in the CU, and the functions of the protocol layers below the PDCP layer (such as the RLC layer and MAC layer, etc.) are set in the DU.

[0066] It will be appreciated that the above division of processing functions between the CU and DU by protocol layer is merely an example, and the division may be performed in other ways. For example, functions of protocol layers above the RLC layer may be located in the CU, while functions of protocol layers below the RLC layer may be located in the DU. Alternatively, the CU or DU may be divided to include functions of more protocol layers, or to include partial processing functions of protocol layers. In one design, partial functions of the RLC layer and functions of protocol layers above the RLC layer are located in the CU, while the remaining functions of the RLC layer and functions of protocol layers below the RLC layer are located in the DU. In another design, the functions of the CU or DU may be divided according to service type or other system requirements, for example, by latency, with functions whose processing time must meet latency requirements located in the DU, and functions that do not meet these latency requirements located in the CU. In another design, the CU may also include one or more functions of the core network. For example, the CU may be located on the network side to facilitate centralized management; the DU may include multiple radio frequency functions, or the radio frequency functions may be remotely located. This is not limited in the present embodiments.

[0067] Exemplarily, the functions of the CU can be implemented by one entity, or can be implemented by different entities. For example, the functions of the CU are further divided, that is, the control plane and the user plane are separated and implemented through different entities, namely the control plane CU entity (i.e., CU-CP entity) and the user plane CU entity (i.e., CU-UP entity). The CU-CP entity and the CU-UP entity can be coupled with the DU to jointly complete the functions of the RAN device. The interface between the CU-CP entity and the CU-UP entity can be an E1 interface, the interface between the CU-CP entity and the DU can be an F1-C interface, and the interface between the CU-UP entity and the DU can be an F1-U interface. Among them, one DU and one CU-UP can be connected to one CU-CP. Under the control of the same CU-CP, one DU can be connected to multiple CU-UPs, and one CU-UP can be connected to multiple DUs.

[0068] The terminal device 102 is an entity on the user side for receiving or transmitting signals, and is mainly used to realize the function of wireless communication with the network device 101.

[0069] For example, terminal device 102 can be an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. The terminal device 102 may also be a mobile phone, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, a wearable device (such as a smart watch, a smart bracelet, a pedometer, etc.), a terminal device in a 5G network, or a future-evolved public land mobile communication network. The terminal device 102 may be a terminal device in a wireless network (PLMN), etc., and the embodiments of the present application do not limit this. The terminal device 102 may be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted, or may be deployed on water (such as ships, etc.), or may be deployed in the air (such as airplanes, balloons and satellites, etc.). In the embodiments of the present application, the terminal device 102 may be a legacy UE, or may be an RB-level partial frequency hopping (RPFS) UE that supports SRS coverage and capacity enhancement, or may be other UEs. The present application does not limit the type of the terminal device 102. Among them, legacy UE refers to user equipment that supports existing mechanisms, for example, user equipment that supports release-15 and release-16.

[0070] In an embodiment of the present application, the terminal device 102 or the network device 101 includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and memory (also known as main memory). The operating system can be any one or more computer operating systems that implement business processing through processes, such as a Linux operating system, a Unix operating system, an Android operating system, an iOS operating system, or a Windows operating system. The application layer includes applications such as browsers, address books, word processing software, and instant messaging software. In addition, the embodiment of the present application does not specifically limit the specific structure of the execution subject of the method provided in the embodiment of the present application.

[0071] It should be noted that the number and type of terminal devices 102 included in the network architecture shown in Figure 1 are merely examples, and the embodiments of the present application are not limited thereto. For example, more or fewer terminal devices 102 communicating with the network device 101 may be included. For the sake of simplicity, they are not described one by one in the accompanying drawings.

[0072] In addition, in the network architecture shown in Figure 1, although network device 101 and terminal device 102 are shown, the application scenario may not be limited to including network device 101 and terminal device 102, for example, it may also include core network equipment or equipment for carrying virtualized network functions, etc.

[0076] Step S201: The network device sends a first configuration to the terminal device, where the first configuration is used to measure M beams; the first configuration is also used to indicate at least one first condition.

[0077] Correspondingly, the terminal device receives the first configuration sent by the network device.

[0078] Exemplarily, the first condition indicated by the first configuration may include at least one of the following: the signal quality of the service beam is less than the first threshold (for convenience of description, referred to as condition 1); or, the improved or reduced signal quality of the service beam is greater than the second threshold (for convenience of description, referred to as condition 2); or, the signal quality of the first beam is greater than the third threshold (for convenience of description, referred to as condition 3), and the first beam and the service beam are different beams; or, the signal quality of the first beam is greater than the signal quality of the service beam and the difference between the signal quality of the first beam and the signal quality of the service beam is greater than the fourth threshold (for convenience of description, referred to as condition 4); or, the signal quality of the first beam is greater than the fifth threshold and the signal quality of the service beam is less than the sixth threshold (for convenience of description, referred to as condition 5); or, the signal quality of the second beam is less than the seventh threshold (for convenience of description, referred to as condition 6), and the second beam is a preset beam; or, the improved or reduced signal quality of the first beam is greater than the eighth threshold (for convenience of description, referred to as condition 7); wherein, the service beam, the first beam, and the second beam belong to M beams.

[0079] Optionally, the first beam in Condition 7 may be the second beam. If the second beam is the anchor beam, Condition 7 is that the signal quality improved or reduced by the anchor beam is greater than an eighth threshold.

[0080] Condition 2 may specifically be that the signal quality of the service beam is improved or decreased within a preset duration T1 by greater than a second threshold, or that the difference between two measurement results of the service beam is greater than the second threshold. Condition 7 may specifically be that the signal quality of the service beam is improved or decreased within a preset duration T2 by greater than the second threshold. This application does not limit the values ​​of T1 and T2. The two measurements are two adjacent measurements or two measurements separated by a certain number of times.

[0081] Optionally, the first condition may be related to the quality of the serving beam, such as indicating that the quality of the serving beam is deteriorating to a certain extent, as described in conditions 1 and 2 above. Alternatively, the first condition may be related to the quality of other beams, such as indicating that the quality of other beams is good to a certain extent, as described in condition 3 above. Alternatively, the first condition may be related to the comparison between the quality of other beams and the quality of the serving beam, such as indicating that the quality of other beams is better than that of the serving beam to a certain extent, as described in conditions 4 and 5 above. Alternatively, the first condition may be related to the quality of the anchor beam (i.e., the second beam described above), such as indicating that the anchor beam is deteriorating to a certain extent, as described in conditions 6 and 7 above. The anchor beam may refer to a preset beam in the group (DU, CU, beam group) to which the serving beam belongs. The anchor beam may be a preconfigured beam, a beam corresponding to a reference signal, or a transmission configuration indication (TCI) state.

[0082] The first configuration for measuring M beams may mean that the first configuration is used by the terminal device to determine which beams to perform layer 1 measurement on. Alternatively, the first configuration is configuration information for the M beams, which is used by the terminal device to determine the M beams. Specifically, the first configuration may be the time-frequency domain location of a beam-related CSI resource set or a related reference signal, which is used to determine the time-frequency domain location of a received reference signal.

[0083] Exemplarily, the first configuration includes at least one of the above first conditions, such as including the above conditions 1 and 2; or,

[0084] The first configuration may include a condition identifier, which is used to indicate the at least one first condition, such as a condition identifier including condition 1.

[0085] Among them, the above-mentioned at least one first condition is used by the terminal device to determine which beams among the M beams to report L1 measurement information, that is, the following N beams are the beams that need to report L1 measurement information determined from the M beams according to the above-mentioned at least one first condition.

[0086] Optionally, the first configuration may further indicate a correspondence between the at least one first condition and the M beams, where the first condition corresponding to each of the M beams is used to determine whether the L1 measurement information of the beam needs to be reported to the network device. Each of the M beams corresponds to at least one first condition; the first conditions corresponding to each beam may be the same or different; and the number of first conditions corresponding to each beam may be the same or different, which is not limited in this application.

[0087] Step S202: The terminal device sends first information to the network device, where the first information includes layer 1 measurement information of N beams, each of the N beams satisfies at least one first condition, N is less than or equal to M, and the N beams belong to M beams.

[0088] Correspondingly, the network device receives the first information sent by the terminal device.

[0089] In some embodiments, the terminal device can determine the beams among the M beams that meet at least one first condition as the above-mentioned N beams based on the layer 1 measurement information corresponding to the M beams; then, send first information to the network device, and the first information includes the layer 1 measurement information of the N beams.

[0090] Exemplarily, the first information includes at least one of the following: an identifier corresponding to one or more first cells, at least one beam among the beams corresponding to the first cell belongs to N beams; or, identifiers of M first conditions; or, first indication information, the first indication information is used to indicate K and / or N, K is the number of first conditions satisfied by the N beams; or, second indication information, the second indication information is used to indicate the beam type among the beam types of the N beams that satisfies a preset beam type, the preset beam type is a synchronization signal / physical broadcast channel block SSB or a channel state information beam CSI-RS; or, third indication information, the third indication information is used for the beam among the N beams that satisfies the preset beam type; or, identifiers corresponding to the N beams; or, an identifier of the BWP; or, the signal quality of the N beams; or, the signal quality of the first cell; or, fourth indication information, the fourth indication information is used to indicate whether there is a timing advance TA.

[0091] Exemplarily, the identifier corresponding to the first cell may specifically be a physical cell identifier PCI or a candidate cell related identifier (such as a candidate ID) or a predefined index.

[0092] Exemplarily, the signal quality of the first cell may be a weighted average or average of the signal qualities of beams belonging to N beams in the beams corresponding to the first cell, or an average of the signal qualities of a preset number of beams in the beams corresponding to the first cell. The preset number of beams may include beams that do not satisfy the first condition. For example, a beams in the beams corresponding to the first cell satisfy the corresponding first condition, and the preset number is b, a<b. Then, the terminal device may select ba beams in addition to a beams from the beams corresponding to the first cell, calculate the average value of the signal qualities of the a beams and the selected ba beams, and use the calculated average value as the signal quality of the first cell.

[0093] Optionally, the first information sent by the terminal device to the network device may further include layer 1 measurement information of a beam in the M beams that does not meet the first condition. Exemplarily, the N beams include a third beam, the third beam and the fourth beam belong to the same cell or the same distribution unit DU or the same centralized unit CU, the fourth beam does not belong to the N beams, and the first information also includes layer 1 measurement information of the fourth beam.

[0094] In some embodiments, before a terminal device sends a first message to a network device, the terminal device may send a second message to the network device, where the second message is used to request an uplink resource used to send the first message. Furthermore, the terminal device sends the first message using the uplink resource. For example, see the embodiment shown in FIG4 .

[0095] Exemplarily, the second information includes at least one of the following: an identifier of one or more CUs (for the convenience of description, referred to as identifier 1); an identifier of one or more DUs (for the convenience of description, referred to as identifier 2); an identifier corresponding to one or more first cells, at least one beam among the beams corresponding to the first cell belongs to N beams; or, identifiers corresponding to M first conditions; or, first indication information, the first indication information is used to indicate K and / or N, K is the number of the first conditions satisfied by the N beams; or, second indication information, the second indication information is used to indicate the beam type among the beam types of the N beams that meets the preset beam type, the preset beam type is the synchronization signal / physical broadcast channel block SSB or the channel state information beam CSI-RS; or, third indication information, the third indication information is used for the beam among the N beams that meets the preset beam type; or, an identifier corresponding to the N beams; or, an identifier of the partial bandwidth BWP; or, an identifier of the logical channel group LCG.

[0096] Optionally, at least one beam among the beams corresponding to each of the one or more CUs in the above-mentioned identifier 1 belongs to N beams; at least one beam among the beams corresponding to each of the one or more DUs in the above-mentioned identifier 2 belongs to N beams.

[0097] Optionally, the terminal device may receive fifth indication information sent by the network device, where the fifth indication information is used to indicate the format of the first information; and then, the first information is sent in the format indicated by the fifth indication information. Exemplarily, the fifth indication information may be an L1 measurement result related to the serving cell; or a measurement result of a candidate cell within a CU (such as an indication of a CU index); or a measurement result corresponding to a reference signal resource, where at least two reference signal resources measured by the measurement result are from cells within different CUs, and at least two reference signal resources belong to reference signal resources corresponding to the above-mentioned M beams.

[0098] In some embodiments, the terminal device may receive a first message from a network device, where the first message is used to request first information; and then send the first information to the network device.

[0099] Exemplarily, the first message may include one of the following: uplink resources, in which case the terminal device may determine the time-frequency domain position for sending the first information based on the uplink resources; or the format of the first information, in which case the terminal device may send the first information after determining the format of the first information; or the content of the specifically requested first information, for example, if the first message includes a CU index, the terminal device may report the L1 measurement result of the CU-related beam in the first information.

[0100] The method embodiment shown in Figure 2 above includes many possible implementation schemes. Some of the implementation schemes are illustrated below in combination with Figures 3 and 4. It should be noted that the relevant concepts, operations or logical relationships not explained in Figures 3 and 4 can refer to the corresponding descriptions in the embodiment shown in Figure 2.

[0101] In this application, the embodiments shown in Figures 3 and 4 can be used as a separate embodiment, and the embodiments shown in Figures 3 and 4 can be independent of the technical solution of Figure 2; some steps in the embodiments shown in Figures 3 and 4 can also be used as separate embodiments.

[0102] In the following embodiments, the communication method provided in this application is introduced in detail by taking the terminal device as UE and the network device as a base station as an example.

[0103] FIG3 is a flow chart of another communication method provided in an embodiment of the present application.

[0104] S301: The base station sends a configuration of an L1 measurement event to a UE, where the configuration includes information of at least one event.

[0105] In the embodiment of the present application, for ease of understanding, the first configuration is referred to as a configuration of an L1 measurement event, and the first condition is referred to as an event.

[0106] The configuration of the L1 measurement event is used by the UE to determine the beam for L1 measurement (ie, the M beams mentioned above).

[0107] Exemplarily, the at least one event may include the following: the signal quality of the serving beam is less than a first threshold (for convenience of description, referred to as event 1); or the signal quality of the serving beam is increased or decreased by more than a second threshold (for convenience of description, referred to as event 2); or the signal quality of the first beam is greater than a third threshold (for convenience of description, referred to as event 3), and the first beam and the serving beam are different beams; or the signal quality of the first beam is greater than the signal quality of the serving beam and the difference between the signal quality of the first beam and the signal quality of the serving beam is greater than a fourth threshold (for convenience of description, referred to as event 4); or the signal quality of the first beam is greater than a fifth threshold and the signal quality of the serving beam is less than a sixth threshold (for convenience of description, referred to as event 5); or the signal quality of the second beam is less than a seventh threshold (for convenience of description, referred to as event 6), and the second beam is a preset beam; or the signal quality of the first beam is increased or decreased by more than an eighth threshold (for convenience of description, referred to as event 7); wherein the serving beam, the first beam, and the second beam belong to M beams. Exemplarily, for a specific description of the events, please refer to the relevant description of the first condition above, which will not be repeated here.

[0108] Optionally, the configuration may further include a beam type (i.e., the fifth indication information). For example, the beam type may be one of intra cell, intra CU, or inter CU. Inter refers to inter-station and intra refers to intra-station.

[0109] In some embodiments, the base station may also send a first message to the UE, where the first message is used to request L1 reporting, and the first message may also include the above-mentioned beam type.

[0110] S302: The UE determines that the reporting format of the L1 measurement result is the first format.

[0111] In some embodiments, if the UE does not receive the beam type, the UE may determine that the reported UCI is in a traditional format, that is, report the L1 measurement result through UCI in the format reported by the serving cell CSI, that is, the first format is the traditional format.

[0112] In other embodiments, when the UE receives a beam type, the UE may determine a reporting format for the L1 measurement result based on the beam type. For example, if the beam type is intra cell, the reported UCI is in a legacy format, i.e., the first format is legacy; if the beam type is intra CU, the reported UCI is in a preset format, such as the R18 LTM format, i.e., the first format is the R18 LTM format; if the beam type is inter CU, the reported UCI or MAC CE is in the format defined in step S305 below, i.e., the first format is the UCI or MAC CE format in step S305.

[0113] Table 1 exemplarily shows an example of the first format.

[0114] Table 1

[0115] The UE can send multiple CSI reports using the format shown in Table 1. Each CSI report includes the indexes of multiple beams and the signal quality corresponding to the beam. Table 1 exemplarily shows a CSI report.

[0116] S303: If the L1 measurement result satisfies the above event, the UE sends second information to the base station, where the second information is used to request uplink resources required for reporting the first information.

[0117] The UE sending the second information to the base station can also be expressed as the UE reporting the second information.

[0118] In some embodiments, the UE performs L1 measurement on M beams to obtain an L1 measurement result corresponding to each beam; the UE judges the L1 measurement result obtained based on an event; if the L1 measurement result satisfies an event, the UE reports second information. Exemplarily, the second information may be carried in a scheduling request (SR) or a buffer status report (BSR) or a newly defined MAC control element (MAC CE) request. Exemplarily, the event satisfied by the L1 measurement result may be event 1 or event 5.

[0119] Optionally, the above-mentioned uplink resources may be predefined.

[0120] Optionally, the second information can also be used by the network to trigger additional measurements. For example, if the quality of a certain cell reported after SSB measurement is good, the measurement of the CSI-RS of the cell can be activated.

[0121] Optionally, the second information includes at least one of the following: (1) an index of a cell that satisfies the event (i.e., the first cell mentioned above), for example, the index of the cell may be a configuration identifier (config ID) of the cell; (2) an index of the event that the beam satisfies; (3) indication information (i.e., second indication information) used to indicate that the reference signal corresponding to the beam that satisfies the event is SSB or CSI-RS; (4) the total number of events that the beam satisfies and / or the total number of beams that satisfy the event, i.e., the first indication information mentioned above; (5) an index of a beam that satisfies the event and whose corresponding reference signal is SSB or CSI-RS; (6) an index of the beam that satisfies the event (e.g., TCI state ID); (7) BWP ID; (8) LCG ID(s).

[0122] Exemplarily, the second information may include the following combinations: (1) reporting the number of events satisfied by the beam or the number of beams that satisfy the event through preset bits (such as 4 bits); (2) the index of the cell that satisfies the event and the beam ID of the beam that satisfies the event; (3) the index of the cell that satisfies the event, the index of the beam that satisfies the event, and the index of the event that the beam satisfies; (4) reporting a traditional BSR, where the buffer size is determined according to the number of events that trigger the report, or a specific value can be used to indicate that the report is triggered by event satisfaction; (5) reporting a traditional SR, where the SR is a specific value, and the specific value is used to indicate that the report is triggered by event satisfaction. Among them, (1) to (4) can be BSRs; (5) can be SRs.

[0123] Optionally, different from traditional SR, for mobility-triggered reporting, the base station can schedule resources in advance after identification.

[0124] S304: The base station schedules uplink resources for the UE based on the second information.

[0125] Exemplarily, the uplink resource is used to report DCI information (format) of physical control information (such as UL grant) of the first information.

[0126] S305: Based on the uplink resources, the UE reports first information to the base station, where the format of the first information is the first format.

[0127] Optionally, the specific content of the first information may be configured by the network, or may be customized / protocol specified.

[0128] In one implementation, the first information can be carried on the MAC CE. Exemplarily, the first information specifically includes at least one of the following: the index (config ID) of the cell that satisfies the event (i.e., the first cell mentioned above); the event index satisfied by the beam, for example, when reporting, it can be reported according to the event index satisfied per cell (per cell) or the event index satisfied by the beam (per beam), that is, it can indicate the correspondence between the first cell and the event or the correspondence between the beam and the event; the number of events satisfied by the beam or the number of beams (i.e., the first indication information mentioned above), the number of events or the number of beams is used to indicate that the second information also includes the number of event-related information blocks (i.e., measurement-related information) corresponding to the number of events or the number of beams, for example, if the number of events satisfied by the beam is 2, the second information may include two sets of measurement-related information; the index of the beam that satisfies the event and the corresponding reference signal SSB or CSI-RS is (i.e., the third indication information), for example, the index is CRI or SSBRI; the index of the beam that satisfies the event (such as beam index, TCI state ID), BWP ID; signal quality of the beam that meets the event; signal quality of the first cell; fourth indication information, the fourth indication information is used to indicate whether there is a timing advance TA, wherein the timing advance TA can be measured by the UE.

[0129] Among them, the first cell may include a serving cell and / or a candidate cell; the signal quality of the beam that meets the event may specifically be: the signal difference with the serving beam, the difference with the beam ranked first in the list, the difference with the anchor beam, and the difference with the beam that meets the event; the signal quality of the cell may be the weighted average or average of the signal qualities of multiple beams that meet the event, or the average of the signal qualities of a preconfigured number of beams.

[0130] The following exemplifies several possible information contents of the first information in the MAC CE.

[0131] Implementation 1: The first information includes an index of a cell satisfying the event, an index of a beam satisfying the event, and a signal quality of the cell satisfying the event. The cell index and the beam index may be arranged in a preset order or according to the signal quality of the cell or the signal quality of the beam.

[0132] Implementation 2: The first information includes the beam that satisfies the event, the index of the event that the beam satisfies, and the signal quality of the serving beam.

[0133] Implementation 3: The first information includes the index of the cell that meets the event, the index of the beam that meets the event and the index of the event that the beam meets the event, the signal quality corresponding to the beam that meets the event, and the number of cells that meet the event or the number of events.

[0134] Table 2 is an exemplary format of the first information.

[0135] Table 2

[0136] Among them, the beam indicated by the beam index is the beam that meets the preset event; the triggering cell is the cell that meets the preset event; the event identifier corresponding to the beam index is used to indicate the event that the beam corresponding to the beam index in Table 2 meets, for example, event ID for RS-0=1, which can indicate that the event identifier corresponding to the beam with beam index RS-0 is 1; the event identifier corresponding to the beam index is used to indicate the event that the beam corresponding to the beam index in Table 2 meets, for example, event ID for RS-0=1, which can indicate that the event identifier corresponding to the beam with beam index RS-0 is 1; the signal quality of the beam indicated by the beam index is used to indicate the signal quality of the beam corresponding to the beam index in Table 2, for example, SINR for RS-0, which can indicate the signal to interference plus noise ratio (SINR) of the beam with beam index RS-0.

[0137] Implementation 4: The first information includes the index of the cell that satisfied the event (e.g., config ID), the time index of the event satisfied by the beam, and the signal qualities corresponding to the multiple beams. The signal qualities corresponding to the multiple beams in the first information can be sorted by signal quality, such as by sequential difference. It should be understood that the event is used to trigger the reporting of the first information, but more beam information is required for judgment. Providing quality signaling for only one beam reduces the overhead, but provides insufficient information.

[0138] Table 3 is another exemplary format of the second information.

[0139] Table 3

[0140] Among them, whether the beam satisfies the event can be indicated by a preset value, such as 1 indicates that the event is satisfied, and 0 indicates that the event is not satisfied. Then, RS-0=1 is used to indicate that the beam with beam index RS-0 satisfies the event, and RS-1=0 is used to indicate that the beam with beam index RS-1 satisfies the event.

[0141] By comparing information 5 in Table 2 with information 7 and information 8 in Table 3, it can be seen that the present application can simultaneously indicate the beam index that satisfies the event and the event that the beam index satisfies through one indication information (such as information 5), or can respectively indicate the beam index that satisfies the event and the event that the beam index satisfies through two separate indication information. For example, information 7 is only used to indicate the beam that satisfies the event but does not indicate the event that the beam satisfies, and information 8 is used to indicate the event that the beam satisfies but does not indicate which beam satisfies the event. The present application does not limit this.

[0142] In another implementation, the first information can be carried on the UCI. Exemplarily, the first information specifically includes at least one of the following: the index of the cell that meets the event (config ID), the index of the beam that meets the event and the corresponding reference signal is SSB or CSI-RS or the index of the beam that meets the event (such as TCI state ID), the signal quality of the beam that meets the event, and the event-related quality (such as the quality of the serving cell or the reference threshold). Exemplarily, the signal quality of the beam signal can be any one of the following: the signal difference with the serving beam, the difference with the first signal quality of the current cell, the difference with the beam with the best signal in the current cell, and the difference with the beam that meets the event.

[0143] Optionally, the second information may include information associated with the first information, wherein the association may mean that part or all of the information in the first information and part or all of the information in the second information belong to the same cell or the same CU, such as the first information includes the identifier of cell 1, and the second information includes the index of the beam in cell 1 and the signal quality of the beam in cell 1; or, the association may mean that the second information indicates the number of cells or CUs corresponding to the data in the first information, that is, how many cells or CUs the data of the first information comes from, for example, the first information includes indication information indicating that the number of cells is 3, and the second information includes cell information of 3 cells.

[0144] For example, when the first information can be carried on UCI, the second information can be a list of cells or a list of CUs that satisfy the event, or the number of cells or the number of CUs. The first information can be sent via multiple UCIs, and the number of UCIs used to send the first information can be the same as the number of cells or the number of CUs. In addition, the order in which the UE sends the multiple UCIs can be determined based on the order of the cells in the cell list or the order of the CUs in the CU list, with the multiple UCIs corresponding one-to-one to the cells in the cell list or one-to-one to the CUs in the CU list.

[0145] For example, the UE sends the second information to the base station. The second information includes a cell list. The cell list includes three cells, which are cell 1, cell 2 and cell 3 in order. Then, after receiving the second information, the base station can schedule the PUSCH of the UE through DCI. Based on PUSCH, the UE schedules three CSIs to report the information corresponding to cell 1, the information corresponding to cell 2 and the information corresponding to cell 3 in turn, where the information corresponding to cell 1, the information corresponding to cell 2 and the information corresponding to cell 3 are the first information mentioned above. Exemplarily, the information corresponding to the cell may include the index of the beam in the beam of the cell that meets the event and the signal quality of the beam. The following examples show several possible information contents of the first information in the UCI:

[0146] Implementation 1: signal quality of the serving beam, index of the cell and beam that satisfies the event, index indicating whether the event is satisfied (0 or 1), where 0 is used to indicate that the beam does not satisfy the event, and 1 is used to indicate that the beam satisfies the event.

[0147] For example, if the first information is carried on the UCI, and the quality corresponding to the relevant beam in the cell is reported, a UCI can be reported for each cell. Reporting the first information through the UCI is faster, but less information can be carried.

[0148] Implementation 2: The index of the cell that meets the event (such as config ID), the index of the beam that meets the event (such as beam ID or TCI state ID), the indexes of the n beams under the cell, and the signal quality corresponding to the beam, where n is a preset value.

[0149] In an embodiment of the present application, an event is used to trigger the reporting of first information, and the first information only includes the signal quality of the beam, reducing signaling overhead. The beam includes the beam that meets the event and the beam that does not meet the event in the cell to which the beam belongs.

[0150] Implementation 3: The index of the cell that satisfies the event (such as config ID), the index of the event that the beam satisfies, the signal quality of the beam that satisfies the event, and the quality of the cell that satisfies the event. The quality of the cell can be obtained by weighted average of the signal quality of the beam that satisfies the event or calculated by other methods. This application does not limit this.

[0151] Among them, the event is used to trigger the reporting of the first information, and the reporting of the satisfied event can be used by the base station to determine whether it is necessary to switch the beam or cell.

[0152] FIG4 is a flow chart of another communication method provided in an embodiment of the present application.

[0153] S401: The base station sends a configuration of an L1 measurement event to a UE, where the configuration includes information of at least one event.

[0154] For example, the specific implementation of step S401 can refer to the relevant content of the above step S301, which will not be repeated here.

[0155] S402: The UE determines that the reporting format of the L1 measurement result is the first format.

[0156] For example, the specific implementation of step S402 can refer to the relevant content of the above step S302, which will not be repeated here.

[0157] S403: The UE reports first information to the base station based on the pre-configured uplink resources, where the format of the first information is the first format.

[0158] Optionally, the specific content of the first information may be configured by the base station, or may be customized / protocol specified.

[0159] Optionally, the first information may be carried in a MAC CE or a UCI. For specific content of the first information when the first information is carried in a MAC CE or a UCI, refer to the above step S305.

[0160] In the embodiment of the present application, the uplink resources for the UE to send the first information are pre-configured, so the UE does not need to request the base station to schedule the uplink resources for sending the first information, which can improve the efficiency of measurement reporting.

[0161] In some other embodiments of the present application, the terminal device may also not distinguish between cells and directly report all RS numbers across CUs, and only report the RS index and related quality. For example, the network device configures the index of the reference signal corresponding to all beams; the terminal device measures the configured reference signal, and if the beam of the reference signal meets the first condition, it reports (i.e., sends it to the base station), and the content of the report is the index of the reference signal and the corresponding quality.

[0162] The present application divides the network equipment and terminal equipment into functional modules according to the above-mentioned method embodiment. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above-mentioned integrated modules can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in this application is schematic and is only a logical functional division. There may be other division methods in actual implementation. The communication device of the embodiment of the present application will be described in detail below with reference to Figures 5 to 7.

[0163] 5 , which is a schematic diagram of a communication device according to an embodiment of the present application, as shown in FIG5 , the communication device may include a processing unit 10 and a transceiver unit 20 .
