Description

Reference signal measurement method and related apparatus

[0001] The present application claims priority from the Chinese Patent Application No. 202410848565.9 filed on June 26, 2024, and entitled "Reference signal measurement method and related apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and in particular to a reference signal measurement method and related apparatus. BACKGROUND

[0003] The fifth generation mobile communication system (5th generation, 5G) can use high frequency communication, that is, use ultra-high frequency band (such as 28 GHz) signal to transmit data. One of the main problems of high frequency communication is that the signal energy decreases sharply with the transmission distance, resulting in short signal transmission distance. In order to overcome this problem, high frequency communication uses analog beam technology, which concentrates signal energy in a small angle range by weighting processing of antenna array, forms a signal similar to a light beam (called analog beam, simply referred to as beam), thereby improving the transmission distance. Both network equipment and terminal equipment need to use beams for transmission. When the network equipment and the terminal equipment perform uplink and downlink data transmission, specific beams need to be used.

[0004] The network equipment and the terminal equipment can select a suitable beam through a beam management process. Then the network equipment and the terminal equipment communicate through the selected beam. The terminal equipment can also continue to measure the signal quality of multiple beams configured by the network equipment for the terminal equipment. Then, the terminal equipment reports the signal quality of at least one beam with good signal quality measured by the terminal equipment according to the reporting resource configured by the network.

[0005] The terminal equipment measures multiple beams to obtain the signal quality of multiple beams and reports the signal quality of multiple beams. The terminal equipment does not distinguish the types of multiple beams. This results in the terminal equipment being unable to measure the signals of different types of beams specifically, and further results in the terminal equipment being unable to report the signal quality of different types of beams specifically. SUMMARY

[0006] The application provides a reference signal measurement method and related devices, which are used to enable a terminal device to determine reference signals corresponding to M serving beams and / or reference signals corresponding to N new beams, measure reference signals corresponding to part or all of the M serving beams, and / or measure reference signals corresponding to part or all of the N new beams respectively. Thus, the terminal device can measure reference signals corresponding to different types of beams. The terminal device can conveniently report measurement results of reference signals corresponding to different types of beams. The network device can make a decision on whether to update the serving beams of the terminal device based on the measurement results of reference signals corresponding to different types of beams.

[0007] The first aspect of the application provides a reference signal measurement method, which can be used in a terminal-side communication device, for example, executed by a terminal device. The terminal device can be a device or apparatus with a chip, or a device or apparatus integrated with a circuit, or a chip, chip system, module, or control unit in the foregoing devices or apparatus. The application does not make any limitation. It should be noted that, in the application, the terminal device can refer to the terminal device itself, or a chip, functional module, or integrated circuit in the terminal device that completes the method provided by the application. The application does not make any limitation. In the first aspect and possible implementation manners, the method is described by taking the terminal device as an example. The method comprises the following steps: a terminal device determines reference signals corresponding to M serving beams and / or reference signals corresponding to N new beams, the N new beams are beams in the terminal device other than the M serving beams, M is an integer greater than or equal to 1, and N is an integer greater than or equal to 1; the terminal device measures reference signals corresponding to part or all of the M serving beams, and / or measures reference signals corresponding to part or all of the N new beams respectively, to obtain first measurement results.

[0008] In the above technical solution, the terminal device measures reference signals corresponding to part or all of the M serving beams, and / or the terminal device measures reference signals corresponding to part or all of the N new beams respectively, to obtain first measurement results.

The terminal device can conveniently report measurement results of reference signals corresponding to different types of beams. The network device can make a decision on whether to update the serving beams of the terminal device based on the measurement results of reference signals corresponding to different types of beams.

[0009] Based on the first aspect, in a possible implementation manner, the method further comprises: the terminal device determines whether at least one event of the terminal device occurs according to the first measurement results.

For example, the terminal device adopts a joint mode, and the terminal device can determine the reference signals corresponding to the M service beams by using the implementation. In the implementation, the TCI state indicated by the network device to the terminal device is a joint TCI state (Joint TCI-State), and the TCI state indicated by the network device to the terminal device is used for uplink and downlink transmission. The TCI state activated by the network device for the terminal device is a joint TCI state, and the TCI state activated by the network device for the terminal device is used for uplink and downlink transmission. For example, the joint state can be used for transmission of at least one of an uplink channel, an uplink signal, uplink data, a downlink channel, a downlink signal, and downlink data. The uplink channel includes at least one of a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH).

[0111] The communication system to which the present application is applicable includes terminal equipment and network equipment. The terminal equipment and network equipment are introduced as follows.

[0112] Terminal device, also known as UE, mobile station (MS), mobile terminal (MT), fixed wireless access (FWA), customer premise equipment (CPE), etc. Terminal device is a device including wireless communication function (providing voice / data connectivity to users). For example, handheld devices with wireless connection function, vehicle-mounted devices, machine type communication (MTC) terminals, etc. At present, terminal devices can include mobile phones, tablets, notebooks, palmtop computers, mobile internet devices (MID), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self driving (e.g. drones, vehicles), wireless terminals in remote medical surgery, wireless terminals in smart grid, wireless terminals in transportation safety, wireless terminals in smart city, or wireless terminals in smart home, etc. For example, wireless terminals in self driving can be drones, helicopters, or airplanes, etc. For example, wireless terminals in Internet of Vehicles can be vehicle-mounted devices, whole vehicle devices, vehicle-mounted modules, vehicles, or ships, etc. Wireless terminals in industrial control can be cameras, robots, or mechanical arms, etc. Wireless terminals in smart home can be televisions, air conditioners, sweeping machines, sound boxes, or set-top boxes, etc. Terminal devices can also be devices or modules with corresponding communication functions accessing the above-mentioned communication systems. Terminal devices are usually provided with communication modules, circuits or chips for executing corresponding communication functions, and terminal devices are also configured with program instructions for executing corresponding communication functions.

[0113] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus integrated with a circuit, or a chip, chip system, module or control unit in the above-mentioned devices or apparatus, and the specific application is not limited. It should be noted that in this application, when referring to terminal devices, it can refer to terminal devices themselves, or chips, functional modules or integrated circuits in terminal devices that complete the methods provided in this application, and the specific application is not limited.

[0114] A network device is a device deployed in a wireless access network to provide wireless communication functions for terminal devices. The network device can also be referred to as a radio access network (RAN) entity, an access node, a network node, an access network device, or a communication apparatus, etc.

[0115] Specifically, the network device can be an access network device of a 3rd generation partnership project (3GPP) related cellular system. For example, a fourth-generation (4G) mobile communication system, a 5G mobile communication system, or a future mobile communication system. The network device can also be an access network device in an open RAN (O-RAN or ORAN) or a cloud radio access network (CRAN). Alternatively, the network device can also be an access network device in a communication system obtained by fusing two or more of the above communication systems.

[0116] The network device includes, but is not limited to, an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (for example, a home evolved NodeB, or home Node B, HNB), a baseband unit (BBU), an access point (AP) in a wireless fidelity (WiFi) system, a macro base station, a micro base station, a wireless relay node, a donor node, a wireless controller in a CRAN scenario, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP). The network device can also be an access network device in a 5G mobile communication system. For example, a next generation NodeB (gNB) in a new radio (NR) system, a TRP, a TP, or one or a group (including multiple antenna panels) of antenna panels of a base station in a 5G mobile communication system. Alternatively, the network device can also be a network node constituting a gNB or a transmission point. For example, a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element. For example, a BBU. The RU can be included in a radio frequency device or a radio frequency unit. For example, in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Alternatively, the network device can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, in V2X technology, the network device can be a road side unit (RSU).

[0117] It should be noted that in different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, the CU can also be referred to as an open centralized unit (O-CU) or an open CU, the DU can also be referred to as an open distributed unit (O-DU), the centralized unit control plane (CU-CP) can also be referred to as an open centralized unit control plane (O-CU-CP) or an open CU-CP, the centralized unit user plane (CU-UP) can also be referred to as an open centralized unit user plane (O-CU-UP) or an open CU-UP, and the RU can also be referred to as an open radio unit (O-RU). The specific application is not limited. Any one of the CU, CU-CP, CU-UP, DU and RU in the present application can be realized by a software module, a hardware module, or a combination of a software module and a hardware module.

[0118] FIG. 1 is a schematic diagram of an ORAN system according to an embodiment of the present application. The ORAN system includes a core network, an access network device and a UE. Optionally, the ORAN system can also include other components in addition to the components shown in FIG. 1, and the specific application is not limited.

[0119] The access network device can communicate with the core network (CN) through a backhaul link. The access network device can communicate with the UE through an air interface. Specifically, the BBU in the access network device communicates with the core network through the backhaul link. The RU in the access network device communicates with at least one UE through the air interface. The BBU communicates with at least one RU through a fronthaul link, and the BBU and the RU can be co-located or not co-located.

[0120] The BBU includes at least one CU and at least one DU, and the CU and the DU can communicate through at least one midhaul link.

[0121] In a possible implementation, as shown in FIG. 2, the CU is a logical node carrying radio resource control (RRC), service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer and other control functions of the access network device. The CU can be connected to network nodes such as a core network through some interfaces. For example, an E2 interface. Optionally, the CU can have part of the functions of the core network. The CU (for example, the PDCP layer and / or higher layer of the CU) is connected to the DU (for example, the radio link control (RLC) layer and lower layer of the DU) through some interfaces. For example, an F1 interface. Optionally, the F1 interface can provide control plane (C-Plane) and user plane (U-Plane) functions (for example, interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is an application protocol of the F1 interface, which defines signaling procedures of the F1 in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0122] Optionally, as shown in FIG. 2, the CU can be split into a CU-CP and a CU-UP, where the CU-CP is a logical node carrying the control plane part of PDCP (PDCP-C) layer of RRC layer and packet data convergence protocol layer, used to implement the control plane function of the CU. The CU-CP can interact with a network element in the core network for implementing the control plane function. The network element in the core network for implementing the control plane function can be an access and mobility function network element, such as an access and mobility management (AMF) in a 5G system. The AMF network element is used to be responsible for mobility management in a mobile network, such as location update of a terminal device, registration network of the terminal device, handover of the terminal device, and the like. The CU-UP is a logical node carrying the user plane part of PDCP (PDCP-U) layer of SDAP layer and packet data convergence protocol layer, used to implement the user plane function of the CU. The CU-UP can interact with a network element in the core network for implementing the user plane function. The network element in the core network for implementing the user plane function, for example, a user plane function (UPF) in a 5G system, is used to be responsible for forwarding and receiving data in a terminal device. The above configuration of the CU and the DU is only an example, and in actual application, the CU and the DU can also be configured to have functions according to needs. For example, the CU or the DU can be configured to have more functions of protocol layers, or the CU or the DU can be configured to have partial processing functions of protocol layers. For example, partial functions of the RLC layer and functions of protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and functions of protocol layers below the RLC layer are arranged in the DU. For another example, the functions of the CU or the DU can be divided according to service types or other system requirements, for example, functions requiring to meet a relatively short delay requirement in processing time are arranged in the DU, and functions not requiring to meet the delay requirement are arranged in the CU.

[0123] In a possible implementation manner, as shown in FIG. 2, the DU is a logical node carrying an RLC layer, a medium access control (MAC) layer, a higher physical layer (Higher PHY), and other functions. In some examples, the DU can control at least one RU. The DU is connected to the RU through some interfaces, which can be a front-haul interface. In some examples, the Higher PHY layer includes part of PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, and the like.

[0124] In one possible implementation, as shown in FIG. 2, the RU is a logical node that hosts lower physical layer (Lower PHY) and radio frequency (RF) processing. In some examples, the RU can be a TRP or a remote radio head (RRH) in 3GPP or other similar functional entity. In some examples, the Low-PHY includes portions of PHY processing such as fast fourier transform (FFT), inverse fast fourier transformation (IFFT), digital beamforming and filtering, etc. processing functions. The RU communicates with one or more UEs over a wireless link.

[0125] The DU and the RU can or can not be co-located. The DU and the RU exchange control plane and user plane information over a front-haul link via a lower-layer split-control, user and synchronization (Lower-Layer Split CUS-Plane, LLS-CUS) interface. The LLS-CUS can include a lower-layer split control (LLS-C) interface and a lower-layer split user (LLS-U) interface that provide control plane (C-Plane) and user plane (U-Plane), respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and the RU. The DU and the RU have a lower-layer split management (LLS-M) interface of the front-haul link to exchange management information, and the management plane (M-Plane) refers to non-real-time management operations between the DU and the RU.

[0126] The DU and the RU can cooperate to collectively implement the functionality of the PHY layer. One DU can be connected to one or more RUs. The functionalities that the DU and the RU have can be configured in multiple ways according to design. For example, the DU is configured to implement baseband functionality, and the RU is configured to implement mid- RF functionality. As another example, the DU is configured to implement high-layer functionality in the PHY layer, and the RU is configured to implement low-layer functionality in the PHY layer or to implement the low-layer functionality and RF functionality. The high-layer functionality in the PHY layer can include a portion of the functionality of the PHY layer that is closer to the MAC layer, and the low-layer functionality in the PHY layer can include another portion of the functionality of the PHY layer that is closer to the mid-RF side.

[0127] The CU (or CU-CP and CU-UP), DU or RU can also have different names in different systems, but those skilled in the art can understand their meanings. For example, in the ORAN system, the CU can also be referred to as O-CU (open CU), the DU can also be referred to as O-DU, the CU-CP can also be referred to as O-CU-CP, the CU-UP can also be referred to as O-CU-UP, and the RU can also be referred to as O-RU. For the convenience of description, the CU, CU-CP, CU-UP, DU and RU are taken as examples for description in this application.

[0128] It should be noted that the network device can be a device or apparatus with a chip, or a device or apparatus integrated with a circuit, or a chip, chip system, module or control unit in the above-mentioned device or apparatus, and the specific application is not limited. It should be noted that in this application, when referring to the network device, it can refer to the network device itself, or the chip, functional module or integrated circuit in the network device that completes the method provided in this application, and the specific application is not limited.

The beamforming technology can be digital beamforming technology, analog beamforming technology, hybrid digital beamforming technology, or hybrid analog beamforming technology, etc.

[0139] A beam is generally associated with a resource, for example, when performing beam measurement, the network device measures different beams through different resources, and the terminal device feeds back the measured resource quality, so that the network device knows the quality of the corresponding beam. When data transmission, beam information is also indicated by its corresponding resource. For example, the network device indicates the information of the physical downlink shared channel (PDSCH) beam of the terminal device through the transmission configuration indication (TCI) field in the DCI.

[0140] In one possible implementation, multiple beams with the same or similar communication characteristics are considered as one beam. One beam can include one or more antenna ports for transmitting data channels, control channels, sounding signals, and the like. One or more antenna ports forming one beam can also be regarded as one antenna port set.

[0141] 2、QCL: Quasi Co-Location is used to indicate that multiple resources have one or more same or similar communication characteristics. For multiple resources with quasi co-location, the same or similar communication configuration can be used. For example, if two antenna ports have quasi co-location, the channel large-scale characteristics of one port transmitting one symbol can be inferred from the channel large-scale characteristics of another port transmitting one symbol. The large-scale characteristics can include delay spread, average delay, Doppler spread, Doppler shift, average gain, reception parameters, terminal device reception beam number, transmission / reception channel correlation, reception angle of arrival, spatial correlation of receiver antennas, main angel-of-arrival (AoA), average angle of arrival, spread of AoA, and the like. Specifically, the co-location indication is used to indicate whether at least two groups of antenna ports have co-location relationship, including: the co-location indication is used to indicate whether the channel state information reference signals sent by at least two groups of antenna ports come from the same transmission point, or the co-location indication is used to indicate whether the channel state information reference signals sent by at least two groups of antenna ports come from the same beam group.

[0142] 3、TCI: Also known as TCI-state. In uplink and downlink transmission, both the network device and the terminal device need to use the correct beam to achieve correct transmission. In downlink transmission, the network device needs to indicate the downlink transmission beam it uses to the terminal device. The terminal device can determine a suitable reception beam according to the downlink transmission beam, which is used to receive information from the network device. In uplink transmission, the network device also needs to indicate to the terminal device which uplink transmission beam the terminal device uses to send information to the network device. The network device can determine the uplink transmission beam with better signal quality of the terminal device. Both the uplink transmission beam and the downlink transmission beam can be indicated by the corresponding TCI state. Specifically, the downlink transmission beam can be indicated by the downlink TCI state, and the uplink transmission beam can be indicated by the uplink TCI state.

[0143] In the 3GPP protocol, the network device can indicate the TCI state to the terminal device through the TCI field in the DCI. The size of the TCI field is 3 bits, which can be specifically represented as 8 different field values (codepoints). Each field value of the TCI field can be associated with an identification of a TCI state. The identification of the TCI state can uniquely identify a TCI state, which can be a downlink TCI state or an uplink TCI state. Each field value of the TCI field can also be associated with two TCI state identifications, which can uniquely identify two TCI states, which can include a downlink TCI state and an uplink TCI state.

[0144] The downlink TCI state includes several parameters, and the terminal device can determine the related information of the downlink transmission beam through these parameters, so as to determine to adopt a suitable receiving beam to receive information from the network device. The TCI state is configured by the network device to each terminal device, and the structure of the downlink TCI state is as follows:

[0145] Each TCI state includes its own identification (tci-StateId) and two quasi-colocation information (QCL-info). Each QCL-info includes a reference signal resource, which is used to indicate that the downlink transmission of the TCI state should adopt the same downlink timing, frequency offset or receiving beam as the reference signal resource. The specific type of the QCL-info determines it. The QCL type can have four values {typeA, typeB, typeC, typeD}. When the QCL type is typeA, typeB and typeC, the same downlink timing and frequency offset as the reference signal resource should be used for downlink transmission. When the QCL type is typeD, the same receiving beam as the reference signal resource should be used for downlink transmission. In the above two QCL-info, one is typeD and the other is typeA or typeB or typeC. The terminal device can determine which receiving beam to use to receive the corresponding downlink transmission through the typeD QCL-info. The specific execution steps are as follows:

[0146] The network device indicates a certain downlink TCI state to the terminal device through DCI. The terminal device determines the reference signal resource in the typeD QCL information of the downlink TCI state. The terminal device takes the receiving beam of the reference signal resource as the receiving beam for downlink transmission. It should be noted that the receiving beam of the reference signal resource is obtained by the terminal device in advance through the beam management process. Through the beam management process, the terminal device can determine which receiving beam is the best to receive the reference signal resource, and take the receiving beam as the receiving beam of the reference signal resource.

[0147] The uplink TCI state includes a reference signal resource, which is used to indicate that the uplink transmission using the TCI state should use the same uplink sending beam as the reference signal resource. The terminal device can determine which sending beam to use for uplink transmission through the reference signal resource. In the uplink TCI state, the reference signal resource is not included in the QCL-info, nor is it distinguished by the QCL type, because it is not necessary to refer to the uplink timing and frequency offset information, but only to the uplink sending beam. The structure of the uplink TCI state is as follows:

[0148] The specific execution steps are as follows:

[0149] The network device indicates a certain uplink TCI state to the terminal device through DCI. The terminal device determines the reference signal resource in the uplink TCI state. The terminal device takes the sending beam of the reference signal resource as the sending beam for uplink transmission. It should be noted that the sending beam of the reference signal resource is obtained by the terminal device in advance through the beam management process.

[0150] The configuration, activation and indication of the TCI state are introduced below.

[0151] TCI-state configuration: The network device configures multiple TCI-states to the terminal device through RRC signaling. These TCI-states all include a typeD QCL-Info. The network device can also configure TCI-states that do not include typeD QCL-info, but these TCI-states are not used for data transmission beam indication, so they are not further described here.

[0152] TCI-state activation: after the network device configures multiple TCI-states, it also needs to activate 8 of them through a medium access control control element (MAC CE). The 8 TCI-states are one-to-one corresponding to the 8 values of the TCI field in the DCI. That is, which 8 TCI-states correspond to the 8 values of the TCI field in the DCI is determined by the MAC CE.

[0153] TCI state indication: the network device indicates a specific TCI-state through the TCI field in the DCI. For example, the value of the TCI field in the DCI sent by the network device to the terminal device is 000, indicating that the data transmission beam adopts the TCI state corresponding to 000. The reference signal contained in the typeD QCL-Info in the TCI state is the CSI-RS with index #1, indicating that the data transmission beam is the same as the receiving beam corresponding to the CSI-RS with index #1. The receiving beam corresponding to the CSI-RS with index #1 can be determined through the beam measurement process and is known to the terminal device. Therefore, through the specific value of the TCI field, the terminal device can determine the beam corresponding to the data transmission beam, and thus transmit or receive data using the corresponding beam.

[0154] It should be noted that the three descriptions of TCI state, TCI-state and TCI state in this paper can be replaced with each other. ID in this application can be translated as identifier, indication, indicator, index, identity, or identification. identifier, indication, indicator, index, identity, identification can be replaced with each other.

[0155] TCI mode: including joint mode and separate mode. The joint mode refers to that the same beam or TCI state is used for uplink transmission and downlink transmission between the TRP (i.e., network device) and the terminal device. The separate mode refers to that different beams or TCI states are used for uplink transmission between the TRP and the terminal device and downlink transmission between the TRP and the terminal device. In this application, the network device can be a TRP or a device containing one or more TRPs. In the joint mode, the TCI state can be referred to as a joint TCI state, which can be used for uplink and downlink transmission. In the separate mode, the TCI state used for downlink transmission can be referred to as a downlink TCI state (dl-TCI-State), and the TCI state used for uplink transmission can be referred to as an uplink TCI state (ul-TCI-State).

[0156] In this application, TCI can be translated as transmission configuration indication or transmission configuration number. The English translation of transmission configuration indication is transmission configuration indicator, or transmission configuration indication.

[0157] In this application, if a TCI state is a downlink TCI state or a joint state, the QCL type D reference signal in the TCI state can be understood as the reference signal corresponding to the reference signal resource in the typeD QCL information in the TCI state. The QCL resource in the TCI state can be understood as the reference signal resource in the typeD QCL information in the TCI state. If a TCI state is an uplink TCI state, the reference signal in the TCI state refers to the reference signal configured in the TCI state. For example, the reference signal configured in ssb-Index-r17, csi-RS-Index-r17 or srs-r17 in the structure of the above uplink TCI state. The reference signal can be a CSI-RS, a SRS or an SSB.

[0158] For a downlink TCI state or a common TCI state, the reference signal associated with the QCL TypeD reference signal of the TCI state: an SSB having a QCL relationship with the QCL TypeD reference signal. The SSB is an SSB corresponding to a source QCL resource of a QCL chain. That is, the source QCL resource is an SSB resource. The QCL chain is determined according to the QCL TypeD reference signal of the TCI state. For example, the QCL resource of the TCI state indicated by the network device for the terminal device is a CSI-RS resource. The QCL resource in the TCI state corresponding to the CSI-RS resource is a tracking reference signal (TRS) resource. The TCI state corresponding to the CSI-RS resource can be understood as the TCI state adopted by the network device to send the CSI-RS resource, or the TCI state adopted by the network device to send the CSI-RS corresponding to the CSI-RS. And the QCL resource in the TCI state corresponding to the TRS resource is an SSB resource. The TCI state corresponding to the TRS resource can be understood as the TCI state adopted by the network device to send the TRS resource, or the TCI state adopted by the network device to send the TRS corresponding to the TRS. As can be seen, the QCL resource (such as a CSI-RS resource) in the TCI state indicated by the network device for the terminal device, the QCL resource (such as a TRS resource) in the TCI state corresponding to the CSI-RS resource, and the QCL resource (such as an SSB resource) in the TCI state corresponding to the TRS resource constitute a QCL chain. The source QCL resource of the QCL chain is an SSB resource, and therefore the reference signal associated with the QCL TypeD reference signal of the TCI state is an SSB corresponding to the SSB resource.

[0159] The reference signal associated with the reference signal in the uplink TCI state: the SSB having a QCL relationship with the reference signal in the uplink TCI state. The SSB is the SSB corresponding to the source QCL resource of the QCL chain. That is, the source QCL resource is an SSB resource. The QCL chain is determined according to the reference signal in the TCI state. For example, the network device indicates the reference signal in the uplink TCI state for the terminal device to be a CSI-RS. The QCL resource in the TCI state corresponding to the CSI-RS resource adopted by the CSI-RS is a TRS resource. The TCI state corresponding to the CSI-RS resource can be understood as the TCI state adopted by the network device to send the CSI-RS resource, or the TCI state adopted by the network device to send the CSI-RS corresponding to the CSI-RS resource. The QCL resource in the TCI state corresponding to the TRS resource is an SSB resource. The TCI state corresponding to the TRS resource can be understood as the TCI state adopted by the network device to send the TRS resource, or the TCI state adopted by the network device to send the TRS corresponding to the TRS resource. As can be seen, the reference signal resource (such as the CSI-RS resource) corresponding to the reference signal in the uplink TCI state indicated by the network device for the terminal device, the QCL resource (such as the TRS resource) in the TCI state corresponding to the CSI-RS resource, and the QCL resource (such as the SSB resource) in the TCI state corresponding to the TRS resource form a QCL chain. The source QCL resource of the QCL chain is an SSB resource, so the reference signal associated with the reference signal in the TCI state is the SSB corresponding to the SSB resource. For another example, the network device indicates the reference signal in the uplink TCI state for the terminal device to be an SRS. The QCL resource in the TCI state corresponding to the SRS resource adopted by the SRS is an SSB resource. The TCI state corresponding to the SRS resource can be understood as the TCI state adopted by the terminal device to send the SRS resource, or the TCI state adopted by the terminal device to send the SRS corresponding to the SRS resource. The reference signal resource in the TCI state corresponding to the SRS resource is an SSB resource. As can be seen, the reference signal resource (such as the SRS resource) corresponding to the reference signal in the uplink TCI state indicated by the network device for the terminal device, and the reference signal resource (such as the SSB resource) in the TCI state corresponding to the SRS resource form a QCL chain. The source QCL resource of the QCL chain is an SSB resource, so the reference signal associated with the reference signal in the TCI state is the SSB corresponding to the SSB resource.

[0160] Currently, the terminal device and the network device select a suitable beam through a beam management process, and communicate through the selected beam. The beam management process includes: first performing beam coarse alignment based on SSB, and then performing beam fine adjustment based on CSI-RS. The beam management process can be divided into three stages, which will be introduced below.

[0161] Phase one: coarse beam alignment between network device and terminal device.

[0162] The base station performs beam sweeping. Specifically, as shown in FIG. 5a, the base station transmits SSBs to the terminal device through beams in different directions at different time instants. Meanwhile, the terminal device sweeps the receiving beam, that is, the terminal device also receives SSBs from the network device through beams in different directions at different time instants. The terminal device determines the beam for the base station to transmit signals and the beam for the terminal device to receive signals according to the received signal strength. The beam for the base station to transmit signals is referred to as base station beam, and the beam for the terminal device to receive signals is referred to as terminal beam.

[0163] Specifically, the base station beam includes The terminal beam includes As shown in FIG. 5b, the base station transmits SSB resource configuration information and reporting resource configuration information to the terminal device. The base station beam includes beams B0 to B15, that is, M = 5. The terminal beam includes beams U0 to U3, that is, N = 4. The base station transmits SSBs to the terminal device through corresponding SSB resources using beam B0, transmits SSBs to the terminal device using beam B1, and so on, and transmits SSBs to the terminal device using beam B5. The terminal device measures the SSBs transmitted by the base station through beams B0 to B5 respectively using beams U0 to U3 respectively, and obtains measurement results. The terminal device can determine the base station beam with better or best signal quality through the measurement results. The terminal device feeds back the base station beam with better or best signal quality to the network device. It should be noted that in phase one, the base station beam and the terminal beam can be understood as wide beams.

[0164] Phase two: base station beam fine adjustment.

[0165] The base station determines a plurality of first candidate beams according to the base station beam with better or best signal quality determined in stage one, each of the first candidate beams being a narrow beam. Specifically, as shown in FIG. 6a, the plurality of first candidate beams include beams S0 to S2. For example, the base station determines the beam B3 in the above-mentioned stage one, the beam B3 being a wide beam, and the base station determines the beams S0 to S2 through the beam B3. The terminal device determines the better terminal beam as the beam U1 through the above-mentioned stage one. As shown in FIG. 6b, the base station sends the CSI-RS configuration information to the terminal device. The network device sends the CSI-RS to the terminal device through the corresponding CSI-RS resource using the beam S0, sends the CSI-RS to the terminal device through the corresponding CSI-RS resource using the beam S1, and sends the CSI-RS to the terminal device through the corresponding CSI-RS resource using the beam S2. The terminal device receives the CSI-RS sent from the base station through different beams through the beam U1 and obtains measurement results. The terminal device can determine the candidate beam with better or best signal quality through the measurement results. The terminal device feeds back the first candidate beam with better or best signal quality to the network device. For example, as shown in FIG. 7, the first candidate beam with better or best signal quality is the beam S1. The base station takes the first candidate beam with better or best signal quality as the beam for communicating with the terminal device.

[0166] Stage three: UE beam refinement.

[0167] The base station sends the CSI-RS to the terminal device using the beam S1, while the terminal device determines the better terminal beam as the beam U1 through the above-mentioned stage one, the beam U1 being a wide beam. The terminal device determines a plurality of second candidate beams through the beam U1, as shown in FIG. 7, the plurality of second candidate beams including beams P1 to P4. The terminal device receives the CSI-RS sent from the base station through the beam S1 through the beams P1 to P4 and obtains measurement results. The terminal device can select one beam from the beams P1 to P4 according to the measurement results and take the beam as the beam for communicating with the network device.

[0168] The network device can configure the terminal device to report the measurement results in one of the following three ways. The three ways specifically include: periodic reporting, semi-persistent reporting, and aperiodic reporting. The semi-persistent reporting is also referred to as semi-static reporting.

[0169] Periodic reporting: the network device sends reference signal resource configuration information to the terminal device. The reference signal resource configuration information includes periodic reference signal resources. The network device configures the terminal device to periodically measure the reference signals. The terminal device can measure the reference signals periodically based on the reference signal resource configuration information, and periodically report the measurement results. Optionally, the measurement results obtained by the terminal device measuring the periodic reference signals can be carried on the PUCCH resource.

[0170] Semi-persistent reporting: the terminal device periodically measures the reference signals, but reports the measurement results in a semi-persistent manner. In one possible implementation, the network device sends reference signal resource configuration information to the terminal device. The reference signal resource configuration information includes periodic reference signal resources. The network device configures the terminal device to periodically measure the reference signals. When the terminal device receives the activation signaling (e.g., MAC CE or DCI) from the network device, the terminal device can continuously report the measurement results. Of course, the network device can also send a deactivation instruction to the terminal device, thereby deactivating the semi-persistent reporting process of the terminal device. In another possible implementation, both the measurement of the reference signals and the reporting of the measurement results are semi-persistent. When the terminal device receives the activation signaling from the network device, the terminal device continuously measures the reference signals and reports the measurement results. When the terminal device receives the deactivation instruction from the network device, the terminal device stops reporting the measurement results. In addition, the measurement results can be carried on the PUCCH resource or the PUSCH resource.

[0171] Aperiodic reporting: when the terminal device receives a trigger instruction (e.g., DCI) from the network device, the terminal device measures the reference signals and reports the measurement results. After completing the reporting, the terminal device stops reporting the measurement results. Optionally, the reference signals can be periodic reference signals, semi-persistent reference signals, or aperiodic reference signals. Optionally, the measurement results are carried on the PUSCH resource.

[0172] As can be seen from the above beam management process, the terminal device measures multiple beams to obtain the signal quality of multiple beams, and reports the signal quality of multiple beams. The terminal device does not distinguish the types of multiple beams. This results in the terminal device being unable to measure the signals of different types of beams, and further results in the terminal device being unable to report the signal quality of different types of beams. The present application provides corresponding technical solutions to enable the terminal device to measure reference signals corresponding to different types of beams. This facilitates the terminal device to report the measurement results of the reference signals corresponding to different types of beams. This is beneficial for the network device to combine the measurement results of the reference signals corresponding to different types of beams to decide whether to update the serving beam of the terminal device.

[0173] The dominant right of the measurement result reporting process of the terminal device before R18 and R18 is in the network device, that is, the network device decides when the terminal device reports the measurement result, which leads to a large uplink resource overhead. Specifically, in the periodic reporting and semi-persistent reporting, the terminal device needs to report the measurement result every other period, and these measurement results may be meaningless to the network side. For example, the measurement results reported by the terminal device twice are not different (for example, the optimal beam does not change), thus causing waste of uplink resources. In R19, event-triggered reporting is introduced. When the conditions of event triggering are met, the terminal device can report the beam measurement result related to the event. Therefore, how to monitor whether the event occurs to trigger the reporting, thereby reducing resource waste, is a problem worth considering. The present application provides a corresponding technical solution for the terminal device to send at least one event-associated measurement result to the network device when at least one event occurs. The terminal device monitors whether at least one event occurs to trigger the reporting of the measurement result. This is beneficial to reduce unnecessary measurement result reporting and avoid resource waste.

[0174] In this application, the event represents an event related to a terminal device initiated report (UE initiated report), or an event related to a terminal device initiated measurement result report, or an event related to a terminal device initiated report (or measurement result) after active measurement, or a specific condition related to a terminal device initiated measurement result report. For example, the terminal device can actively perform measurement (such as beam measurement, or channel measurement, etc.), and then obtain a measurement result related to the event. For another example, the terminal device can perform measurement based on a reference signal according to the configuration of the reference signal resource, and then obtain a measurement result related to the event. For another example, the terminal device actively measures, and reports a measurement result related to the event when a specific condition is met. For another example, the terminal device measures a reference signal related to the event to obtain a measurement result, and then the terminal device determines whether to report the measurement result to the network device according to the measurement result. The terminal device can determine whether a specific condition is met or whether the event occurs, and if so, the terminal device reports the corresponding measurement result. The event can also be referred to as any of the following: a trigger event, a layer 1 (L1) trigger event, a channel state information (CSI) measurement report trigger event, a beam measurement report trigger event, an L1 CSI report trigger event, an L1 beam measurement report trigger event, etc. The naming of the event is not limited in the embodiments of this application. The report triggered by the event or the report can be referred to as any of the following: an event related report, an event triggered or UE initiated report, an event triggered or UE initiated beam report, an event triggered or UE initiated CSI report, an event triggered or UE initiated beam measurement result report, an event triggered or UE initiated interference measurement report, an interference measurement report, a CSI report, a beam measurement result report, etc.

[0175] In the present application, optionally, the signal quality can be a reference signal received power (RSRP), a signal to interference plus noise ratio (SINR), a layer 1 reference signal received power (L1-RSRP), a layer 1 signal to interference plus noise ratio (L1-SINR), a synchronization signal reference signal received power (SS-RSRP), a channel status information reference signal received power (CSI-RSRP), a synchronization signal signal to interference plus noise ratio (SS-SINR), or a channel status information signal to interference plus noise ratio (CSI-SINR), and the present application is not limited in this regard.

[0177] In this application, the terms cell, serving cell, component carrier (CC) and the like can be replaced with each other. The serving cell can be a primary cell (Pcell), a secondary cell (Scell), or a primary secondary cell (PScell). The cell of a primary component carrier (PCC) can be referred to as a Pcell, and the cell of a secondary component carrier (SCC) can be referred to as a Scell. In addition, the cell can also be a neighboring cell of the serving cell (such as a cell corresponding to an additional physical cell identifier (PCI), a candidate cell, etc.

[0178] The technical solutions of the application will be described below in conjunction with specific embodiments.

[0179] FIG. 8 is a schematic diagram of an embodiment of a reference signal measurement method according to the application. Referring to FIG. 8, the method comprises:

[0180] 801. The terminal device determines reference signals corresponding to M serving beams and / or reference signals corresponding to N new beams.

[0181] Wherein, M is an integer greater than or equal to 1, and N is an integer greater than or equal to 1. For example, M can be 1 or 2. The N new beams are beams in the terminal device other than the M serving beams. For example, the N new beams are candidate beams of the terminal device. For example, the N new beams are beams corresponding to TCI states other than the TCI states indicated for the terminal device in the TCI states configured by the network device for the terminal device. For another example, the N new beams are beams corresponding to TCI states other than the TCI states indicated for the terminal device in the TCI states configured or activated by the network device for the terminal device.

[0182] The reference signals corresponding to the M serving beams refer to reference signals used for monitoring the serving beams, or reference signals used for monitoring events related to the serving beams. One serving beam corresponds to one reference signal, and different serving beams can correspond to the same reference signal or different reference signals.

[0183] The reference signals corresponding to the N new beams refer to reference signals used for monitoring the new beams, or reference signals used for monitoring events related to the new beams. One new beam corresponds to one reference signal, and different new beams can correspond to the same or different reference signals.

[0184] The reference signal can be understood as a reference signal resource, or as a reference signal carried on the reference signal resource.

[0185] The following describes a manner in which the terminal device determines the reference signals corresponding to the M service beams in combination with the TCI mode adopted by the terminal device.

[0186] I. The terminal device adopts a common mode.

[0187] In the common mode, the reference signals corresponding to the M service beams can be determined according to any one or more of the following implementation manners 1 and 2.

[0188] Implementation manner 1: The reference signals corresponding to the M service beams are reference signals associated with the TCI states indicated by the network device for the terminal device.

[0189] The TCI states indicated by the network device for the terminal device are common TCI states. The common TCI states are TCI states in a downlink / common TCI state list. The common states are used for uplink / downlink transmission.

[0190] Optionally, the reference signals associated with the TCI states are QCL type D reference signals of the TCI states, or reference signals associated with the QCL type D reference signals of the TCI states. For reference signals associated with the QCL type D reference signals of the TCI states, please refer to the foregoing relevant description.

[0191] It should be noted that in the common mode, if the terminal device performs transmission with a single TRP, the network device indicates one TCI state for the terminal device. If the terminal device performs transmission with multiple TRPs, the network device indicates multiple TCI states for the terminal device, i.e., the indicated TCI states are multiple common TCI states.

[0192] Optionally, the terminal device receives high-layer signaling from the network device, and the high-layer signaling is used to configure a downlink / joint TCI state list (dl-OrJointTCI-StateList) for the terminal device. If the downlink / joint TCI state list includes one TCI state, the TCI state is a TCI state indicated by the network device for the terminal device. If the downlink / joint TCI state list includes multiple TCI states, the terminal device receives a MAC CE from the network device, and the MAC CE is used to activate one or more TCI states in the downlink / joint TCI state list. If the MAC CE activates only one TCI state, the TCI state is a TCI state indicated by the network device for the terminal device. If the MAC CE activates multiple TCI states, the terminal device receives a DCI from the network device, and the DCI includes a transmission configuration indication field, and the transmission configuration indication field is used to indicate one of the TCI states activated by the MAC CE. In this case, the TCI state is a TCI state indicated by the network device for the terminal device.

[0193] Implementation 2: The reference signal corresponding to the M service beams is a reference signal with the worst signal quality or the best signal quality among the reference signals associated with the TCI state activated by the network device for the terminal device.

[0194] In this case, the TCI state activated by the network device for the terminal device is a joint TCI state. The joint TCI state is a TCI state in the downlink / joint TCI state list. The joint state is used for uplink and downlink transmission.

[0195] When the reference signal corresponding to the M service beams includes multiple reference signals, the reference signal corresponding to the M service beams can include multiple reference signals with the worst signal quality or the best signal quality among the reference signals associated with the TCI state activated by the network device for the terminal device. For example, one code point of a MAC CE corresponds to two joint TCI states, and the reference signal corresponding to the M service beams can include a reference signal with the worst signal quality or the best signal quality among the reference signals associated with the first joint TCI state of each code point in all code points in the MAC CE and a reference signal with the worst signal quality or the best signal quality among the reference signals associated with the second joint TCI state of each code point in all code points in the MAC CE.

[0196] Implementation 3: The reference signal corresponding to the M service beams is a reference signal with the worst signal quality or the best signal quality among the TCI states indicated by the network device for the terminal device.

[0197] The TCI state activated by the network device for the terminal device is a common TCI state. The common TCI state is a TCI state in a downlink / common TCI state list. The common state is used for uplink / downlink transmission.

[0198] If the terminal device transmits with the multi-TRP, the network device indicates multiple TCI states for the terminal device, that is, the indicated TCI state is multiple common TCI states. The reference signal corresponding to the M service beams includes a reference signal of the multiple common TCI states.

[0199] Optionally, the reference signal associated with the TCI state is a QCL type D reference signal of the TCI state, or a reference signal associated with the QCL type D reference signal of the TCI state. For reference signals associated with the QCL type D reference signal of the TCI state, please refer to the foregoing related introduction.

[0200] The above-mentioned implementation mode 2 is only an example. For example, the reference signal corresponding to the M service beams can also be: a reference signal with a signal quality greater than a first preset threshold value in the reference signal associated with the TCI state activated by the network device for the terminal device; or a reference signal with a signal quality greater than or equal to a first preset threshold value in the reference signal associated with the TCI state activated by the network device for the terminal device; or a reference signal with a signal quality less than a second preset threshold value in the reference signal associated with the TCI state activated by the network device for the terminal device; or a reference signal with a signal quality less than or equal to a second preset threshold value in the reference signal associated with the TCI state activated by the network device for the terminal device.

[0201] II. The terminal device adopts a separation mode.

[0202] The terminal device adopts a separation mode, and the reference signal corresponding to the M service beams can be determined according to any one or more of the following implementation modes 1-10.

[0203] Implementation mode 1: The reference signal corresponding to the M service beams is a reference signal associated with a first downlink TCI state.

[0204] The first downlink TCI state is a downlink TCI state indicated by the network device for the terminal device, or is a downlink TCI state of a reference signal with the best or worst signal quality among reference signals associated with downlink TCI states activated by the network device for the terminal device, or is a downlink TCI state of a reference signal with signal quality greater than a third preset threshold value among reference signals associated with downlink TCI states activated by the network device for the terminal device, or is a downlink TCI state of a reference signal with signal quality greater than or less than a fourth preset threshold value among reference signals associated with downlink TCI states activated by the network device for the terminal device, or is a downlink TCI state of a reference signal with signal quality less than the fourth preset threshold value among reference signals associated with downlink TCI states activated by the network device for the terminal device, or is a downlink TCI state of a reference signal with signal quality less than or equal to the fourth preset threshold value among reference signals associated with downlink TCI states activated by the network device for the terminal device.

[0205] Optionally, the reference signal associated with the first downlink TCI state is a QCL type D reference signal of the first downlink TCI state, or is a reference signal associated with the QCL type D reference signal of the first downlink TCI state. The reference signal associated with the QCL type D reference signal of the first TCI state is similar to the reference signal associated with the QCL type D reference signal of the aforementioned TCI state, and specific reference can be made to the foregoing relevant description.

[0206] It should be noted that in the separation mode, if the terminal device performs transmission with a single TRP, the network device indicates one first downlink TCI state for the terminal device. If the terminal device performs transmission with multiple TRPs, the network device indicates multiple first downlink TCI states for the terminal device, and each TRP corresponds to one first downlink TCI state.

[0207] In this implementation manner, the first downlink TCI state is a downlink TCI state (dL-TCI state) or a TCI state. The first downlink TCI state is a TCI state in a downlink / joint TCI state list (dl-OrJointTCI-StateList).

[0208] Optionally, the terminal device receives high layer signaling from the network device, the high layer signaling being used to configure a downlink / joint TCI state list (dl-OrJointTCI-StateList) and an uplink TCI state list (ul-TCI-StateList) for the terminal device. If the downlink / joint TCI state list contains only one TCI state, the TCI state is a downlink TCI state indicated by the network device for the terminal device. If the downlink / joint TCI state list contains multiple TCI states, the terminal device receives a MAC CE from the network device, the MAC CE being used to activate one or more pairs of TCI states, each pair of TCI states containing a downlink TCI state list and an uplink TCI state, the downlink TCI state in each pair of TCI states being from the downlink / joint TCI state list. The uplink TCI state in each pair of TCI states is from the uplink TCI state list. If the MAC CE activates only one pair of TCI states, the downlink TCI state in the pair of TCI states is a downlink TCI state indicated by the network device for the terminal device. If the MAC CE activates multiple pairs of TCI states, the terminal device receives a DCI from the network device, the DCI including a TCI field, the TCI field being used to indicate one of the pairs of TCI states activated by the MAC CE, and the downlink TCI state in the pair of TCI states is a downlink TCI state indicated by the network device for the terminal device.

[0209] Implementation 2: The reference signals corresponding to the M service beams are reference signals associated with a first uplink TCI state.

[0210] The first uplink TCI state is an uplink TCI state indicated by the network device for the terminal device, or the first uplink TCI state is an uplink TCI state of a reference signal with the best or worst signal quality among reference signals associated with the activated uplink TCI states of the network device for the terminal device, or the first uplink TCI state is an uplink TCI state of a reference signal with a signal quality greater than a fifth preset threshold value among reference signals associated with the activated uplink TCI states of the network device for the terminal device, or the first uplink TCI state is an uplink TCI state of a reference signal with a signal quality greater than or equal to a fifth preset threshold value among reference signals associated with the activated uplink TCI states of the network device for the terminal device, or the first uplink TCI state is an uplink TCI state of a reference signal with a signal quality less than a sixth preset threshold value among reference signals associated with the activated uplink TCI states of the network device for the terminal device, or the first uplink TCI state is an uplink TCI state of a reference signal with a signal quality less than or equal to a sixth preset threshold value among reference signals associated with the activated uplink TCI states of the network device for the terminal device.

[0211] Optionally, the reference signal associated with the first uplink TCI state is a reference signal in the first uplink TCI state, or a reference signal associated with a reference signal in the first uplink TCI state. The reference signal in the first uplink TCI state can refer to the foregoing description of the reference signal in the TCI state, and the reference signal associated with the reference signal in the first uplink TCI state can refer to the foregoing description of the reference signal associated with the reference signal in the TCI state.

[0212] It should be noted that in the separation mode, if the terminal device transmits with a single TRP, the network device indicates one first uplink TCI state for the terminal device. If the terminal device transmits with multiple TRPs, the network device indicates multiple first uplink TCI states for the terminal device, one first uplink TCI state corresponding to each TRP.

[0213] In this implementation, the first uplink TCI state is an uplink TCI state (ul-TCI-State) or a TCI state. The first uplink TCI state is a TCI state in an uplink TCI state list (ul-TCI-StateList).

[0214] Optionally, the terminal device receives high-layer signaling from the network device, and the high-layer signaling is used to configure the terminal device with a downlink / common TCI state list (dl-OrJointTCI-StateList) and an uplink TCI state list (ul-TCI-StateList). If the uplink TCI state list contains only one TCI state, the TCI state is the uplink TCI state indicated by the network device for the terminal device. If the uplink TCI state list contains multiple TCI states, the terminal device receives a MAC CE from the network device, and the MAC CE is used to activate one or more pairs of TCI states. Each pair of TCI states contains a downlink / common TCI state list and an uplink TCI state, and the downlink / common TCI state in each pair of TCI states is from the downlink / common TCI state list. The uplink TCI state in each pair of TCI states is from the uplink TCI state list. If the MAC CE activates only one pair of TCI states, the uplink TCI state in the pair of TCI states is the uplink TCI state indicated by the network device for the terminal device. If the MAC CE activates multiple pairs of TCI states, the terminal device receives a DCI from the network device, and the DCI includes a TCI field, which is used to indicate one pair of TCI states activated by the MAC CE. The uplink TCI state in the pair of TCI states is the uplink TCI state indicated by the network device for the terminal device.

[0215] In an implementation, the reference signals corresponding to the M serving beams include reference signals associated with the first downlink TCI state and reference signals associated with the first uplink TCI state.

[0216] Optionally, the reference signals associated with the first downlink TCI state and the reference signals associated with the first uplink TCI state are of the same reference signal type, for example, both are SSBs or both are CSI-RSs.

[0217] For the first uplink TCI state and the first downlink TCI state, refer to the foregoing relevant descriptions, which will not be repeated here.

[0218] In an implementation, if the reference signal associated with the first uplink TCI state is the same as the QCL Type-D reference signal of the first downlink TCI state, the reference signals corresponding to the M serving beams include one reference signal, i.e., the reference signal corresponding to the M serving beams is the reference signal in the first uplink TCI state or the QCL Type-D reference signal of the first downlink TCI state.

[0219] For the first uplink TCI state and the first downlink TCI state, refer to the foregoing relevant descriptions, which will not be repeated here.

[0220] For example, if the reference signal in the first uplink TCI state is the same as the QCL Type-D reference signal of the first downlink TCI state, the reference signals corresponding to the M serving beams include one reference signal, i.e., the reference signal corresponding to the M serving beams is the reference signal in the first uplink TCI state or the QCL Type-D reference signal of the first downlink TCI state.

[0221] For example, if the reference signal in the first uplink TCI state is the same as the QCL Type-D reference signal of the first downlink TCI state, the reference signals corresponding to the M serving beams include one reference signal, i.e., the reference signal corresponding to the M serving beams is the reference signal in the first uplink TCI state or the QCL Type-D reference signal of the first downlink TCI state.

[0222] In an implementation, if the reference signal associated with the first uplink TCI state is the same as the QCL Type-D reference signal of the first downlink TCI state, the reference signals corresponding to the M serving beams include one reference signal, i.e., the reference signal corresponding to the M serving beams is the reference signal in the first uplink TCI state or the QCL Type-D reference signal of the first downlink TCI state.

[0223] Optionally, if the reference signal associated with the first uplink TCI state and the reference signal associated with the first downlink TCI state are both downlink reference signals, and the reference signal associated with the first uplink TCI state and the reference signal associated with the first downlink TCI state are not the same, and the reference signal associated with the first uplink TCI state and the reference signal associated with the first downlink TCI state have the same reference signal type (for example, both are SSB or CSI-RS), the reference signals corresponding to the M service beams include the reference signal associated with the first uplink TCI state and the reference signal associated with the first downlink TCI state.

[0224] For the first uplink TCI state and the first downlink TCI state, refer to the foregoing related description, which will not be repeated here.

[0225] In a possible implementation manner, if the reference signal in the first uplink TCI state and the QCL type D reference signal of the first downlink TCI state are both downlink reference signals, and the reference signal in the first uplink TCI state is a CSI-RS, and the reference signal in the first uplink TCI state and the QCL type D reference signal of the first downlink TCI state are not the same, the reference signals corresponding to the M service beams include two reference signals, that is, the reference signal in the first uplink TCI state and the QCL type D reference signal of the first downlink TCI state. Optionally, when the first condition is met, the reference signals corresponding to the M service beams can be determined by using this implementation manner. The first condition includes at least one of the following: the reference signals corresponding to the N new beams configured by the network device for the terminal device are CSI-RSs, the reference type configured by the network device for monitoring the service beams is a CSI-RS, or the reference type configured by the network device for monitoring the new beams is a CSI-RS.

[0226] In another possible implementation manner, if the reference signal associated with the reference signal in the first uplink TCI state and the reference signal associated with the QCL type D reference signal of the first downlink TCI state are not the same, the reference signals corresponding to the M service beams include two reference signals, that is, the reference signal associated with the reference signal in the first uplink TCI state and the reference signal associated with the QCL type D reference signal of the first downlink TCI state. Optionally, when the second condition is met, the reference signals corresponding to the M service beams can be determined by using this implementation manner. The second condition includes at least one of the following: the reference signals corresponding to the N new beams configured by the network device for the terminal device are SSBs, the reference type configured by the network device for monitoring the service beams is an SSB, or the reference type configured by the network device for monitoring the new beams is an SSB.

[0227] In another possible implementation, if the reference signal in the first uplink TCI state and the reference signal associated with the QCL Type-D reference signal of the first downlink TCI state are not the same, and the reference signal in the first uplink TCI state is an SSB, the reference signals corresponding to the M service beams include two reference signals, i.e., the reference signal in the first uplink TCI state and the reference signal associated with the QCL Type-D reference signal of the first downlink TCI state. Optionally, when the second condition is met, the reference signals corresponding to the M service beams can be determined in this implementation. For the second condition, refer to the foregoing relevant description.

[0228] Implementation 6: If the reference signal associated with the first uplink TCI state is an uplink reference signal, the reference signals corresponding to the M service beams include the reference signal associated with the first downlink TCI state.

[0229] For the first uplink TCI state and the first downlink TCI state, refer to the foregoing relevant description, which will not be repeated here.

[0230] For example, if the reference signal in the first uplink TCI state is an uplink reference signal, the reference signals corresponding to the M service beams include one reference signal, i.e., the reference signal associated with the first downlink TCI state.

[0231] Implementation 7: If the reference signal associated with the first uplink TCI state is an uplink reference signal, the reference signals corresponding to the M service beams include the reference signal associated with the first downlink TCI state and the path loss reference signal in the first uplink TCI state, which is the path loss reference signal corresponding to the path loss reference signal identifier (PathlossReferenceRS-Id) in the first uplink TCI state.

[0232] For the first uplink TCI state and the first downlink TCI state, refer to the foregoing relevant description, which will not be repeated here.

[0233] For example, if the reference signal in the first uplink TCI state is an uplink reference signal, the reference signals corresponding to the M service beams include the QCL Type-D reference signal of the first downlink TCI state and the path loss reference signal in the first uplink TCI state.

[0234] In a possible implementation, if the reference signal in the first uplink TCI state is an uplink reference signal, the reference signals corresponding to the M service beams include the reference signal associated with the QCL Type D reference signal of the first downlink TCI state and the path loss reference signal in the first uplink TCI state.

Optionally, the path loss reference signal in the first uplink TCI state is a CSI-RS. For the first condition, refer to the foregoing relevant description.

[0236] It should be noted that the reference signal type of the reference signals corresponding to the service beams can be a CSI-RS or an SSB. The reference signal type can be configured by the network device, or determined implicitly according to the reference signal type of the reference signal corresponding to the new beam, that is, the reference signal type of the reference signal corresponding to the new beam is the same as the reference signal type of the reference signals corresponding to the service beams. It should also be noted that the path loss reference signal in the first uplink TCI state can be a CSI-RS or an SSB, and then when the reference signal corresponding to the service beam of the terminal device is a CSI-RS or an SSB, the path loss reference signal in the first uplink TCI state that is the same as the reference signal type of the reference signal corresponding to the service beam can be used as the reference signal corresponding to the M service beams.

The path loss reference signal in the first uplink TCI state is SSB. The reference signals corresponding to the M service beams are determined by the implementation 13 when the second condition is met. The second condition is described above.

[0256] It should be noted that the network device can configure the terminal device to determine the reference signals corresponding to the M service beams by using one of the above-mentioned implementation manners 1 to 3, or the communication protocol can stipulate that the terminal device determines the reference signals corresponding to the M service beams by using one of the above-mentioned implementation manners 1 to 3, or the network device can configure the terminal device to determine the reference signals corresponding to the M service beams by using one of the above-mentioned implementation manners 1 to 3 in combination with the capability information of the terminal device. For example, whether the terminal device supports measuring the reference signal associated with the first uplink TCI state, or whether the terminal device supports measuring the reference signals corresponding to multiple TCI states. Alternatively, the terminal device can determine the reference signals corresponding to the M service beams by using one of the above-mentioned implementation manners 4 to 13, that is, the terminal device determines the reference signals corresponding to the M service beams by using the corresponding rules.

[0257] Alternatively, the reference signals corresponding to the M service beams can also be explicitly configured by the network device for the terminal device. Alternatively, the embodiment shown in FIG. 8 further includes step 801a. Step 801a can be performed before step 801.

[0258] 801a. The network device sends first configuration information to the terminal device. Correspondingly, the terminal device receives the first configuration information from the network device.

[0259] The first configuration information is used to configure the reference signals corresponding to the M service beams. That is, the first configuration information can include the reference signal information corresponding to the M service beams, or the reference signal resource information of the reference signals corresponding to the M service beams. For example, the first configuration information includes the reference signal indexes corresponding to the M service beams.

[0260] Alternatively, when the network device does not configure the reference signals corresponding to the M service beams, the terminal device can determine the reference signals corresponding to the M service beams by using one of the above-mentioned implementation manners 1 to 10.

[0261] Optionally, the network device configures the terminal device to adopt a joint mode, which can be indicated by at least one of the following: the terminal device receives third configuration information from the network device, a value of a unified TCI state type (unifiedTCI-StateType) field in the third configuration information is joint; the terminal device receives a downlink / joint TCI state list (dl-OrJointTCI-StateList) configured by the network device for the terminal device, and the downlink / joint TCI state list does not contain an uplink TCI state list (ul-TCI-StateList); or the terminal device receives first DCI from the network device, a TCI field in the first DCI indicates a TCI state, and the TCI state corresponds to a TCI state in MAC CE activation, that is, the TCI state is a joint TCI state (dl-OrJointTCI-State). In the joint mode, the network device indicates a joint TCI state to the terminal device, and the joint TCI state can be used for both downlink transmission and uplink transmission. A QCL type D reference signal of the joint TCI state is a downlink reference signal. It should be noted that in the joint mode, a TCI state in the downlink / joint TCI state list can be understood as a joint TCI state.

[0262] Optionally, the network device configures the terminal device to adopt a separate mode, which can be indicated by at least one of the following: the terminal device receives fourth configuration information from the network device, a value of a unified TCI state type (unifiedTCI-StateType) field in the fourth configuration information is separate; the terminal device receives a downlink / joint TCI state list (dl-OrJointTCI-StateList) and an uplink TCI state list (ul-TCI-StateList) configured by the network device for the terminal device; or the terminal device receives second DCI from the network device. A TCI field in the second DCI indicates two TCI states, one is a downlink TCI state (dl-OrJointTCI-State), and the other is an uplink TCI state (ul-TCI-State), and the two TCI states correspond to a pair of TCI states in MAC CE activation. A QCL type D reference signal of the downlink TCI state is a downlink reference signal. A QCL type D reference signal of the uplink TCI state can be an uplink reference signal or a downlink reference signal. The downlink TCI state is used for downlink transmission, and the uplink TCI state is used for uplink transmission. It should be noted that in the separate mode, a TCI state in the downlink / joint TCI state list can be understood as a downlink TCI state.

[0263] The following describes a manner in which the terminal device determines reference signals corresponding to N new beams in combination with a TCI mode adopted by the terminal device.

[0264] I. The terminal device adopts a joint mode. Optionally, the reference signals corresponding to the N new beams comprise reference signals associated with TCI states corresponding to the N new beams.

[0265] Each of the N new beams corresponds to a TCI state. The TCI states corresponding to the N new beams are TCI states configured or activated by the network device for the terminal device, except for a TCI state indicated by the network device for the terminal device.

[0266] In the joint mode, the TCI states corresponding to the N new beams are joint TCI states, which can be used for simultaneous uplink and downlink transmission.

[0267] Optionally, the reference signals associated with the TCI states corresponding to the N new beams are QCL Type D reference signals of the TCI states corresponding to the N new beams, or reference signals associated with the QCL Type D reference signals of the TCI states corresponding to the N new beams.

[0268] In this implementation, the TCI states configured or activated by the network device for the terminal device are joint TCI states (Joint TCI-State) or TCI states.

[0269] II. The terminal device adopts a separate mode.

[0270] Implementation 1: The reference signals corresponding to the N new beams comprise reference signals associated with at least one second uplink TCI state.

[0271] The at least one second uplink TCI state is an uplink TCI state configured or activated by the network device for the terminal device, except for an uplink TCI state indicated by the network device for the terminal device.

[0272] In this implementation, the at least one second uplink TCI state is an uplink TCI state (ul-TCI-State).

[0273] Optionally, the reference signals associated with the at least one second uplink TCI state comprise reference signals in the at least one second uplink TCI state, or reference signals associated with the reference signals in the at least one second uplink TCI state.

[0274] Optionally, the at least one second uplink TCI state is an uplink TCI state in an uplink TCI state list (ul-TCI-StateList) configured by the network device for the terminal device.

[0275] Implementation 2: The reference signals corresponding to the N new beams comprise reference signals associated with at least one second downlink TCI state.

[0276] The at least one second downlink TCI state is a downlink TCI state configured or activated by the network device for the terminal device other than a downlink TCI state indicated by the network device for the terminal device.

[0277] In the implementation, the at least one second downlink TCI state is a downlink TCI state (dl-TCI-State) or a TCI state.

[0278] Optionally, the reference signal associated with the at least one second downlink TCI state includes a QCL Type D reference signal of the at least one second downlink TCI state or a reference signal associated with the QCL Type D reference signal of the at least one second downlink TCI state.

[0280] Implementation 3: The reference signals corresponding to the N new beams include the reference signal associated with the at least one second uplink TCI state and the reference signal associated with the at least one second downlink TCI state.

[0281] For the at least one second uplink TCI state, the at least one second downlink TCI state, the reference signal associated with the at least one second uplink TCI state, and the reference signal associated with the at least one second downlink TCI state, refer to the foregoing relevant descriptions, which will not be repeated here.

[0282] It should be noted that the network device can configure the terminal device to determine the reference signals corresponding to the N new beams by using one of the above-mentioned implementation 1 to implementation 3, or the communication protocol stipulates that the terminal device determines the reference signals corresponding to the N new beams by using one of the above-mentioned implementation 1 to implementation 3, or the network device configures the terminal device to determine the reference signals corresponding to the N new beams by using one of the above-mentioned implementation 1 to implementation 3 in combination with the capability information of the terminal device. For example, whether the terminal device supports the measurement of the reference signal associated with the uplink TCI state.

[0283] It should be noted that the reference signals corresponding to the N new beams can be reference signals corresponding to TCI states configured by the network device for the terminal device, or reference signals corresponding to TCI states configured by the network device for the terminal device and dedicated for measuring the new beams, or reference signals corresponding to TCI states activated by the network device for the terminal device. The reference signals corresponding to the TCI states activated by the network device for the terminal device can be reference signals corresponding to part of the TCI states configured by the network device for the terminal device, for example, at most eight or eight pairs of TCI states activated by MAC CE. Alternatively, the reference signals corresponding to the TCI states activated by the network device for the terminal device can be reference signals corresponding to part of the TCI states configured by the network device for the terminal device and dedicated for measuring the new beams, for example, part of the TCI states configured by the network device for the terminal device and dedicated for measuring the new beams activated by MAC CE or DCI.

[0284] Optionally, the reference signals corresponding to the N new beams can be explicitly configured by the network device for the terminal device. Optionally, the embodiment shown in FIG. 8 further includes step 801b. Step 801b can be performed before step 801.

[0285] 801b. The network device sends second configuration information to the terminal device. Correspondingly, the terminal device receives the second configuration information from the network device.

[0286] The second configuration information is used to configure the reference signals corresponding to the N new beams. That is, the second configuration information can include reference signal information corresponding to the N new beams, or reference signal resource information adopted by the reference signals corresponding to the N new beams. For example, the second configuration information includes reference signal indexes corresponding to the N new beams.

[0287] It should be noted that if the embodiment shown in FIG. 8 includes step 801a, there is no fixed execution order between step 801a and step 801b. For example, step 801a can be performed first, and then step 801b can be performed. Alternatively, step 801b can be performed first, and then step 801a can be performed. Alternatively, steps 801a and 801b can be performed at the same time according to the situation, and the specific application is not limited.

[0288] Optionally, the first configuration information and the second configuration information are the same configuration information.

[0289] Optionally, when the network device does not configure the reference signals corresponding to the N new beams, the terminal device can determine the reference signals corresponding to the N new beams by using one of the above-mentioned implementation modes 1 to 3.

[0290] It should be noted that the above step 801b shows an implementation manner in which the terminal device uses the reference signal configured by the second configuration information as the reference signal corresponding to the N new beams. In actual application, the terminal device can also receive indication information from the network device. The indication information is used to activate or indicate all or part of the reference signals configured by the second configuration information, and then the terminal device uses the reference signals activated or indicated by the indication information as the reference signals corresponding to the N new beams. Optionally, the indication information is carried in DCI or MAC CE.

[0291] Optionally, the types of the reference signals corresponding to the M service beams are the same as the types of the reference signals corresponding to the N new beams.

[0292] In a possible implementation manner, the network device configures the terminal device with the types of the reference signals corresponding to the M service beams, and / or configures the terminal device with the types of the reference signals corresponding to the N new beams.

[0293] In another possible implementation manner, the network device configures the terminal device with the type of the reference signal used for event monitoring. That is, the type of the reference signal corresponding to the M service beams and the type of the reference signal corresponding to the N new beams should both be the type of the reference signal used for event monitoring. Optionally, the reference signals corresponding to the M service beams include the reference signal associated with the first downlink TCI state and / or the reference signal associated with the first uplink TCI state.

[0294] If the type of the reference signal used for event monitoring is SSB, the reference signal associated with the first downlink TCI state should be the reference signal associated with the QCL type D reference signal in the first downlink TCI state. If the reference signal in the first uplink TCI state is SSB, the reference signal associated with the first uplink TCI state is the reference signal in the first uplink TCI state; if the reference signal in the first uplink TCI state is SRS or CSI-RS, the reference signal associated with the first uplink TCI state should be the reference signal associated with the reference signal in the first uplink TCI state, that is, SSB.

[0295] If the type of the reference signal for event monitoring is CSI-RS, the reference signal associated with the first downlink TCI state should be the QCL Type D reference signal of the first downlink TCI state; and if the reference signal in the first uplink TCI state is CSI-RS, the reference signal associated with the first uplink TCI state is the reference signal in the first uplink TCI state; if the reference signal in the first uplink TCI state is SRS or SSB, the terminal device does not need to monitor the reference signal associated with the first uplink TCI state. That is, the reference signals corresponding to the M service beams include the reference signal associated with the first downlink TCI state, but do not include the reference signal associated with the first uplink TCI state.

[0296] In another possible implementation, the type of the reference signal corresponding to the M service beams is determined according to the reference signals corresponding to the N new beams configured by the network device for the terminal device, if the type of the reference signals corresponding to the N new beams is SSB, the type of the reference signal corresponding to the M service beams is SSB; if the type of the reference signals corresponding to the N new beams is CSI-RS, the type of the reference signal corresponding to the M service beams is CSI-RS.

[0297] Optionally, the reference signal corresponding to the M service beams includes the reference signal associated with the first downlink TCI state and / or the reference signal associated with the first uplink TCI state.

[0298] If the type of the reference signals corresponding to the N new beams is SSB, the reference signal associated with the first downlink TCI state should be the QCL Type D reference signal associated with the first downlink TCI state. And if the reference signal in the first uplink TCI state is SSB, the reference signal associated with the first uplink TCI state is the reference signal in the first uplink TCI state; if the reference signal in the first uplink TCI state is SRS or CSI-RS, the terminal device does not need to monitor the reference signal associated with the first uplink TCI state. That is, the reference signals corresponding to the M service beams include the reference signal associated with the first downlink TCI state, but do not include the reference signal associated with the first uplink TCI state.

[0299] If the type of the reference signals corresponding to the N new beams is CSI-RS, the reference signal associated with the first downlink TCI state should be the QCL Type D reference signal of the first downlink TCI state; and if the reference signal in the first uplink TCI state is CSI-RS, the reference signal associated with the first uplink TCI state is the reference signal in the first uplink TCI state; if the reference signal in the first uplink TCI state is SRS or SSB, the terminal device does not need to monitor the reference signal associated with the first uplink TCI state. That is, the reference signals corresponding to the M service beams include the reference signal associated with the first downlink TCI state, but do not include the reference signal associated with the first uplink TCI state.

[0300] In another possible implementation, the reference signal type corresponding to the N new beams is determined according to the reference signals corresponding to the M serving beams configured by the network device for the terminal device, if the reference signal type corresponding to the M serving beams is SSB, then the reference signal type corresponding to the N new beams is SSB; if the reference signal type corresponding to the M serving beams is CSI-RS, then the reference signal type corresponding to the N new beams is CSI-RS.

[0301] Optionally, the reference signals corresponding to the N new beams include at least one reference signal associated with a second uplink TCI state and at least one reference signal associated with a second downlink TCI state.

[0302] If the reference signals corresponding to the M serving beams are SSBs, the at least one reference signal associated with the second downlink TCI state should be the reference signal associated with the QCL type D reference signal in the at least one second downlink TCI state. And the reference signal in the at least one second uplink TCI state is the SSB in the at least one second uplink TCI state and / or the reference signal associated with the reference signal in the at least one second uplink TCI state.

[0303] If the reference signals corresponding to the M serving beams are CSI-RSs, the at least one reference signal associated with the second downlink TCI state should be the QCL type D reference signal in the at least one second downlink TCI state. And the reference signal in the at least one second uplink TCI state is the CSI-RS in the at least one second uplink TCI state.

[0304] Optionally, the embodiment shown in FIG. 8 further includes step 801c. Step 801c can be performed before step 801.

[0305] 801c. The terminal device sends the capability information to the network device. Correspondingly, the network device receives the capability information from the terminal device.

[0306] The capability information includes at least one of the following: the capability of the terminal device supporting event-triggered reporting; one or more events corresponding to the event-triggered reporting supported by the terminal device; the number of serving beams measured by the terminal device; the number of new beams measured by the terminal device; the maximum number of serving beams measured by the terminal device; or the maximum number of new beams measured by the terminal device; or the uplink TCI state associated reference signal measured by the terminal device.

[0307] If the terminal reports the capability information, it indicates that the terminal supports the capability indicated by the capability information; if the terminal does not report the capability information, it indicates that the terminal does not support the capability indicated by the capability information. Alternatively, if the terminal reports the capability information, it indicates that the terminal supports the capability indicated by the capability information; if the terminal reports the non-support capability information, it indicates that the terminal does not support the capability indicated by the capability information. Alternatively, the terminal device can report part of the capability information, and when the terminal device supports the capability indicated by the part of the capability information, it implicitly indicates that the terminal device supports the capability indicated by another part of the capability information, but the terminal device can not report the other part of the capability information. For example, the terminal device indicates to the network device that the terminal device supports the capability of event triggered reporting, and the communication protocol stipulates that the terminal device supporting the event triggered reporting supports the triggered reporting of all events, which is not limited in the present application.

[0308] The event triggered reporting can be event triggered beam reporting, CSI reporting, beam measurement result reporting, interference measurement reporting, etc., which is not limited. As an example, the event triggered reporting can also be referred to as user equipment initiated report (UE initiated report).

[0309] It should be noted that if the embodiment shown in FIG. 8 includes step 801a, there is no fixed execution order between step 801a and step 801c. Step 801a can be executed first, and then step 801c can be executed; or step 801c can be executed first, and then step 801a can be executed; or steps 801a and 801c can be executed simultaneously according to the situation, which is not limited in the present application.

[0310] It should be noted that if the embodiment shown in FIG. 8 includes step 801b, there is no fixed execution order between step 801b and step 801c. Step 801b can be executed first, and then step 801c can be executed; or step 801c can be executed first, and then step 801b can be executed; or steps 801b and 801c can be executed simultaneously according to the situation, which is not limited in the present application.

[0311] It should be noted that if the embodiment shown in FIG. 8 includes step 801a and step 801b, there is no fixed execution order between step 801a, step 801b and step 801c. For example, step 801a can be executed first, then step 801b can be executed, and finally step 801c can be executed; or step 801b can be executed first, then step 801a can be executed, and finally step 801c can be executed, which is not limited in the present application.

[0312] Optionally, the embodiment shown in FIG. 8 further includes step 801d. Step 801d can be executed before step 801.

[0313] 801d、The network device sends fifth configuration information to the terminal device. Correspondingly, the terminal device receives the fifth configuration information from the network device.

[0314] The fifth configuration information is used to configure one or more events for the terminal device. For example, the fifth configuration information includes indexes of the one or more events. Alternatively, the fifth configuration information includes an event table, and the event table includes indexes of the one or more events.

[0315] Optionally, the network device sends activation signaling to the terminal device. Correspondingly, the terminal device receives the activation signaling from the network device. The activation signaling is used to activate part or all of the one or more events.

[0316] Further, optionally, the network device sends deactivation signaling to the terminal device. Correspondingly, the terminal device receives the deactivation signaling from the network device. The deactivation signaling is used to deactivate part or all of the one or more events.

[0317] Optionally, the one or more events include at least one of the following:

[0318] 1. The signal quality of the serving beam of the terminal device is less than a first threshold value, or the signal quality of the serving beam of the terminal device is less than or equal to a first threshold value.

[0319] 2. The difference between the signal quality of at least one new beam and the signal quality of the serving beam of the terminal device is greater than a second threshold value, or the difference between the signal quality of at least one new beam and the signal quality of the serving beam of the terminal device is greater than or equal to a second threshold value.

[0320] 3. The signal quality of one new beam is greater than a third threshold value, or the signal quality of one new beam is greater than or equal to a third threshold value.

[0321] 4.

Optionally, the fifth threshold value is greater than the fourth threshold value, or the fifth threshold value is greater than or equal to the fourth threshold value.

[0322] 5. The difference between the signal quality of the serving beam of the terminal device and the signal quality of the beam corresponding to the reference signal (i.e., SSB) associated with the QCL Type D reference signal of the TCI state corresponding to the serving beam of the terminal device is greater than a sixth threshold value; or the difference between the signal quality of the serving beam of the terminal device and the signal quality of the beam corresponding to the reference signal (i.e., SSB) associated with the QCL Type D reference signal of the TCI state corresponding to the serving beam of the terminal device is greater than or equal to the sixth threshold value.

[0323] Specifically, the TCI state corresponding to the serving beam of the terminal device is the QCL Type D reference signal in the TCI state indicated by the network device for the terminal device. For example, the QCL Type reference signal can be a CSI-RS. The reference signal associated with the QCL Type D reference signal in the TCI state indicated by the network device for the terminal device is an SSB. The signal quality of the SSB is higher than the signal quality of the CSI-RS, or the signal quality of the CSI-RS is lower than the signal quality of the SSB. The difference between the signal quality of the SSB and the signal quality of the CSI-RS is the sixth threshold value.

[0324] 6. The absolute difference between the signal quality of the at least one new beam and the signal quality of the serving beam of the terminal device is less than a seventh threshold value; or the absolute difference between the signal quality of the at least one new beam and the signal quality of the serving beam of the terminal device is less than or equal to the seventh threshold value.

[0325] 7. The signal quality of the serving beam of the terminal device does not belong to the K beams with the best signal quality measured by the terminal device. K is an integer of 1.

[0326] 8. The difference between the signal quality of the at least one new beam and the signal quality of the reference signal with the worst signal quality in the reference signal associated with the TCI state activated by the network device for the terminal device is greater than an eighth threshold value; or the difference between the signal quality of the at least one new beam and the signal quality of the reference signal with the worst signal quality in the reference signal associated with the TCI state activated by the network device for the terminal device is greater than or equal to the eighth threshold value.

[0327] In this implementation, the serving beam of the terminal device can be the beam corresponding to the reference signal with the worst signal quality in the reference signal associated with the TCI state activated by the network device for the terminal device.

[0328] 9. The difference between the signal quality of the at least one new beam and the signal quality of the reference signal with the best signal quality among the reference signals associated with the TCI states activated by the network device for the terminal device is greater than a ninth threshold value; or the difference between the signal quality of the at least one new beam and the signal quality of the reference signal with the best signal quality among the reference signals associated with the TCI states activated by the network device for the terminal device is greater than or equal to the ninth threshold value.

[0329] In this implementation, the serving beam of the terminal device can be a beam corresponding to a reference signal with the best signal quality among the reference signals associated with the TCI states activated by the network device for the terminal device.

[0330] 10. The difference between the signal quality of the at least one new beam and the signal quality of the reference signal configured by the network device for the terminal device is greater than a tenth threshold value; or the difference between the signal quality of the at least one new beam and the signal quality of the reference signal configured by the network device for the terminal device is greater than or equal to the tenth threshold value.

[0331] It should be noted that the first threshold value to the tenth threshold value can be dBm (decibel milliwatt) or dB (decibel) respectively. The first threshold value to the tenth threshold value can be configured or indicated by the network device, or specified by the communication protocol, or determined according to the capability of the terminal device, which is not limited in the present application. For example, the second threshold value can be greater than or equal to 0, such as 3 dB.

[0332] 802. The terminal device measures the reference signals corresponding to part or all of the M serving beams and / or the reference signals corresponding to part or all of the N new beams to obtain a first measurement result.

[0333] Optionally, the first measurement result includes at least one of the following: indexes of part or all of the M serving beams, signal qualities of the reference signals corresponding to part or all of the M serving beams, indexes of part or all of the N new beams, or signal qualities of the reference signals corresponding to part or all of the N new beams.

[0334] Optionally, the embodiment shown in FIG. 8 further includes step 803. Step 803 can be performed after step 802.

[0335] 803. The terminal device determines whether at least one event of the terminal device occurs according to the first measurement result.

[0336] For example, the event configured by the network device for the terminal device is that there is at least one new beam whose signal quality is greater than the signal quality of the serving beam, and the signal quality of the at least one new beam is greater than the signal quality of the serving beam by a second threshold value. When the event occurs, it indicates that there is at least one new beam whose signal quality is greater than the signal quality of the serving beam by the second threshold value. That is, the terminal device can monitor whether the event occurs through the first measurement result.

[0337] For another example, the event configured by the network device for the terminal device is that the signal quality of the serving beam of the terminal device is less than a first threshold value. When the event occurs, it indicates that the signal quality of the serving beam is less than the first threshold value. That is, the terminal device can monitor whether the event occurs through the first measurement result.

[0338] Optionally, the embodiment shown in FIG. 8 further includes step 804. Step 804 can be performed after step 802.

[0339] 804. When at least one event occurs, the terminal device sends the measurement result associated with the at least one event to the network device. Correspondingly, the network device receives the measurement result associated with the at least one event from the terminal device. The measurement result associated with the at least one event belongs to the first measurement result. For example, the first measurement result includes the signal quality of M serving beams and the signal quality of N new beams. The event configured by the network device for the terminal device is that there is at least one new beam whose signal quality is greater than the signal quality of the serving beam, and the signal quality of the at least one new beam is greater than the signal quality of the serving beam by a second threshold value. The measurement result associated with the at least one event can include the signal quality of the at least one new beam.

[0340] Optionally, the terminal device can also send the measurement result irrelevant to the at least one event to the network device. For example, the terminal device reports the measurement result other than the measurement result associated with the at least one event in the first measurement result to the network device.

[0341] Optionally, the terminal device can also send the measurement result that does not satisfy the condition for the event to occur to the network device. For example, the event configured by the network device for the terminal device is that the difference between the signal quality of at least one new beam and the signal quality of the serving beam of the terminal device is greater than a second threshold value. The measurement result associated with the at least one event can include the signal quality of the at least one new beam that satisfies the condition for the event to occur, and also include the signal quality of G new beams that do not satisfy the condition for the event to occur, G being an integer greater than or equal to 0 and less than P-1.

[0342] Optionally, if the embodiment shown in FIG. 8 includes step 803, step 804 can be performed after step 803.

[0343] Optionally, the measurement result associated with the at least one event comprises at least one of the following:

[0344] 1. indexes of K serving beams, the K serving beams belong to M serving beams, K is an integer greater than or equal to 1 and less than or equal to M.

[0345] 2. signal quality of a reference signal corresponding to the K serving beams.

[0346] 3. indexes of P new beams, the P new beams belong to the N new beams, P is an integer greater than or equal to 1 and less than or equal to N.

[0347] 4. signal quality of a reference signal corresponding to the P new beams.

[0348] For example, the event configured by the network device for the terminal device is that there is at least one new beam whose signal quality is greater than that of a serving beam, and the signal quality of the at least one new beam and the signal quality of the serving beam are greater than a second threshold value. Then the measurement result associated with the event can comprise at least one of the following: the index of the at least one new beam, the index of the serving beam, the signal quality of the at least one new beam, or the signal quality of the serving beam.

[0349] In a possible implementation, the index of each serving beam in the K serving beams is indicated by a value of one bit. The network device configures two reference signals corresponding to the M serving beams for the terminal device. The value of one bit is used to indicate that the reference signal corresponding to the serving beam is one of the two reference signals corresponding to the M serving beams configured by the network device. For example, when the value of one bit is 0, it indicates that the reference signal corresponding to the serving beam is the reference signal with a smaller index in the two reference signals corresponding to the M serving beams configured by the network device; when the value of one bit is 1, it indicates that the reference signal corresponding to the serving beam is the reference signal with a larger index in the two reference signals corresponding to the M serving beams configured by the network device. Alternatively, when the value of one bit is 1, it indicates that the reference signal corresponding to the serving beam is the reference signal with a larger index in the two reference signals corresponding to the M serving beams configured by the network device; when the value of one bit is 0, it indicates that the reference signal corresponding to the serving beam is the reference signal with a smaller index in the two reference signals corresponding to the M serving beams configured by the network device.

[0350] In another possible implementation, the index of each serving beam is indicated by a value of S bits. The network device configures W reference signals corresponding to the M serving beams for the terminal device.

[0351] Optionally, S is equal to log2[W]. For example, the network device configures two reference signals corresponding to M service beams for the terminal device. Therefore, S = 1. When the value of the S bit is 0, it indicates that the reference signal corresponding to the service beam is the reference signal with a smaller index among the two reference signals corresponding to the M service beams configured by the network device; when the value of the S bit is 1, it indicates that the reference signal corresponding to the service beam is the reference signal with a larger index among the two reference signals corresponding to the M service beams configured by the network device. Alternatively, when the value of the S bit is 0, it indicates that the reference signal corresponding to the service beam is the reference signal with a larger index among the two reference signals corresponding to the M service beams configured by the network device; when the value of the S bit is 1, it indicates that the reference signal corresponding to the service beam is the reference signal with a smaller index among the two reference signals corresponding to the M service beams configured by the network device.

[0352] Optionally, S is equal to M. For example, the network device configures two reference signals corresponding to M service beams for the terminal device, that is, M = 2, and therefore S = 2. For example, when the value of the S bit is 00, it indicates that the reference signal corresponding to the service beam is the reference signal with a smaller index among the two reference signals corresponding to the two service beams configured by the network device. When the value of the S bit is 01, it indicates that the reference signal corresponding to the service beam is the reference signal with a larger index among the two reference signals corresponding to the two service beams configured by the network device. For another example, when the value of the S bit is 01, it indicates that the reference signal corresponding to the service beam is the reference signal with a smaller index among the two reference signals corresponding to the two service beams configured by the network device. When the value of the S bit is 11, it indicates that the reference signal corresponding to the service beam is the reference signal with a larger index among the two reference signals corresponding to the two service beams configured by the network device.

[0353] In another possible implementation, the index of each serving beam is indicated by a value of one bit. Optionally, the value of the one bit is used to indicate that the reference signal corresponding to the serving beam is a reference signal associated with a first downlink TCI state indicated by the network device for the terminal device, or the reference signal corresponding to the serving beam is a reference signal associated with a first uplink TCI state indicated by the network device for the terminal device. For example, when the value of the one bit is 0, it indicates that the reference signal corresponding to the serving beam is a reference signal associated with a first downlink TCI state indicated by the network device for the terminal device. When the value of the one bit is 1, it indicates that the reference signal corresponding to the serving beam is a reference signal associated with a first uplink TCI state indicated by the network device for the terminal device. Alternatively, when the value of the one bit is 0, it indicates that the reference signal corresponding to the serving beam is a reference signal associated with a first uplink TCI state indicated by the network device for the terminal device. When the value of the one bit is 1, it indicates that the reference signal corresponding to the serving beam is a reference signal associated with a first downlink TCI state indicated by the network device for the terminal device. Here, the value of the one bit is only an example, and more bits can be used to indicate the reference signal corresponding to the serving beam in actual application.

[0354] In another possible implementation, the index of each serving beam is indicated by a value of one bit. Optionally, the value of the one bit is used to indicate that the reference signal corresponding to the serving beam is a reference signal associated with a smaller-indexed reference signal of two TCI states indicated by the network device for the terminal device, or the reference signal corresponding to the serving beam is a reference signal associated with a larger-indexed reference signal of the two TCI states indicated by the network device for the terminal device. For example, when the value of the one bit is 0, it indicates that the reference signal corresponding to the serving beam is a reference signal associated with a smaller-indexed reference signal of two TCI states indicated by the network device for the terminal device. When the value of the one bit is 1, it indicates that the reference signal corresponding to the serving beam is a reference signal associated with a larger-indexed reference signal of the two TCI states indicated by the network device for the terminal device. Alternatively, when the value of the one bit is 0, it indicates that the reference signal corresponding to the serving beam is a reference signal associated with a larger-indexed reference signal of two TCI states indicated by the network device for the terminal device. When the value of the one bit is 1, it indicates that the reference signal corresponding to the serving beam is a reference signal associated with a smaller-indexed reference signal of the two TCI states indicated by the network device for the terminal device. Here, the value of the one bit is only an example, and more bits can be used to indicate the reference signal corresponding to the serving beam in actual application.

[0355] In another possible implementation, the indexes of the K service beams are indicated by a two-bit value. The two-bit value is used to indicate that the reference signals corresponding to the K service beams are reference signals associated with a first downlink TCI state indicated by the network device for the terminal device, or are reference signals associated with a first uplink TCI state indicated by the network device for the terminal device, or are reference signals associated with the first downlink TCI state and reference signals associated with the first uplink TCI state, or are reference signals associated with the first downlink TCI state and a loss reference signal in the first uplink TCI state. For example, the two-bit value is 00, indicating that the reference signals corresponding to the K service beams are reference signals associated with the first downlink TCI state indicated by the network device for the terminal device. The two-bit value is 01, indicating that the reference signals corresponding to the K service beams are reference signals associated with the first uplink TCI state indicated by the network device for the terminal device. The two-bit value is 10, indicating that the reference signals corresponding to the K service beams are reference signals associated with the first downlink TCI state and a loss reference signal in the first uplink TCI state. Alternatively, the two-bit value is 10, indicating that the reference signals corresponding to the K service beams are reference signals associated with the first downlink TCI state indicated by the network device for the terminal device. The two-bit value is 01, indicating that the reference signals corresponding to the K service beams are reference signals associated with the first uplink TCI state indicated by the network device for the terminal device. The two-bit value is 11, indicating that the reference signals corresponding to the K service beams are reference signals associated with the first downlink TCI state and a loss reference signal in the first uplink TCI state. Here, the two-bit value is only an example, and more bits can be used to indicate the reference signals corresponding to the K service beams in actual applications.

[0356] It should be noted that if the K service beams include one service beam, the terminal device can not report the index of the service beam. Alternatively, if the K service beams include multiple service beams, the terminal device can also not report the indexes of the K service beams, and the signal qualities of the K service beams are sorted in a specific order. For example, the signal quality corresponding to the reference signals associated with the first downlink TCI state indicated by the network device for the terminal device is placed at the front, and the signal quality corresponding to the reference signals associated with the first uplink TCI state indicated by the network device for the terminal device is placed at the rear.

[0357] It should be noted that in addition to the above-mentioned manners, the terminal device can also report the indexes of the K service beams, or the indexes of the reference signals corresponding to the K service beams in actual applications.

[0358] Some possible reporting forms of the indexes of the P new beams are introduced below.

[0359] 1. The P new beams are indicated by the TCI states corresponding to the P new beams, and the index of each new beam in the P new beams is indicated by the value of X bits, and the value of the X bits is used to indicate the TCI state corresponding to the new beam. Q is the number of TCI states corresponding to the N new beams.

[0360] Optionally, the TCI states corresponding to the N new beams are the TCI states activated or configured by the network device for the terminal device. In this implementation manner, some possible indication manners of the index of each new beam in the P new beams are introduced below.

[0361] Implementation manner one: the index of each new beam in the P new beams is indicated by the value of X bits. The 2 X values of the X bits correspond to the code points corresponding to the TCI states of the N new beams. When the value of the X bits is the i-th value in the 2 X values, the new beam indicated by the value of the X bits is the beam corresponding to the TCI state of the code point corresponding to the value.

[0362] The 2 X values are sorted in ascending order or descending order according to the values. i is an integer greater than or equal to 1 and less than or equal to 2 X . Each TCI state in the TCI states corresponding to the N new beams has a corresponding code point. Optionally, the code point corresponding to each TCI state is the code point used to activate the TCI state in the first signaling. The first signaling is used by the network device to activate part of the TCI states configured by the network device for the terminal device, for example, the first signaling is a MAC CE. Or, the first signaling is used by the network device to activate part of the TCI states configured by the network device for the terminal device for new beam monitoring, for example, the first signaling is a MAC CE or a DCI. For example, the network device activates eight TCI states for the terminal device, and the corresponding code points are 000 to 111. The value of X is 3, and the values of the three bits include eight possible values of 000 to 111. For example, when the value of the X bits is 000, it indicates that the new beam indicated by the value of the X bits is the beam corresponding to the TCI state with the code point 000. When the value of the X bits is 001, it indicates that the new beam indicated by the value of the X bits is the beam corresponding to the TCI state with the code point 001. Similarly, when the value of the X bits is 111, it indicates that the new beam indicated by the value of the X bits is the beam corresponding to the TCI state with the code point 111.

[0363] Implementation Method 2: The index of each of the P new beams is indicated by the value of X bits. X bits are 2 X The value of each bit corresponds to the TCI state of the N new beams. The value of X bits is 2. X When the value of the i-th value is selected, the new beam indicated by the value of the X bits is the beam corresponding to the i-th TCI state among the N new beams.

[0364] Among them, 2 X The values ​​are sorted in ascending or descending order, where i is greater than or equal to 1 and less than or equal to 2. X The N new beams are integers. The TCI states corresponding to these N new beams are sorted in ascending or descending order of their TCI state indices.

[0365] It should be noted that if the terminal device adopts the common mode, the TCI states corresponding to the N new beams in the above implementation methods one to two are common TCI states. If the terminal device adopts the separate mode, the TCI states corresponding to the N new beams in the above implementation methods one to two are downlink TCI states or uplink TCI states.

[0366] Implementation Method 3: The index of each of the P new beams is indicated by the value of X bits. X bits are 2 X The value of each bit corresponds to the TCI state of the N new beams. The value of X bits is 2. X When the value of the X bit is the i-th value among the possible values, the new beam indicated by the value of the X bit is the i-th TCI state among the TCI states corresponding to the N new beams.

[0367] Among them, 2 X The values ​​are sorted either in ascending order or descending order. In this implementation, the terminal device adopts a split mode, and the TCI states corresponding to the N new beams include uplink TCI states and downlink TCI states. There are multiple ways to sort the TCI states corresponding to the N new beams; two possible implementations are described below.

[0368] 1. The TCI states corresponding to the N new beams include uplink TCI states and downlink TCI states. The uplink TCI states in the N new beam TCI states are ordered either before or after the downlink TCI states. The uplink TCI states in the N new beam TCI states are sorted in descending or ascending order of their indices. The downlink TCI states in the N new beam TCI states are sorted in descending or ascending order of their indices.

[0369] 2、The TCI states corresponding to the N new beams include uplink TCI states and downlink TCI states. The TCI states corresponding to the N new beams are sorted in descending order or ascending order according to the code points corresponding to the TCI states. In the TCI states corresponding to the same code point, the uplink TCI state is arranged before or after the downlink TCI state.

[0370] In this implementation, the TCI states corresponding to the N new beams include one or more pairs of TCI states, and each pair of TCI states includes an uplink TCI state and a downlink TCI state. Each pair of TCI states corresponds to a code point, and the code point corresponding to each pair of TCI states is the code point used by the second signaling to activate the pair of TCI states. The second signaling is used by the network device to activate part of the pairs of TCI states configured by the network device for the terminal device from the pairs of TCI states configured by the network device for the terminal device. For example, the second signaling is a MAC CE. Alternatively, the second signaling is used by the network device to activate part of the pairs of TCI states configured by the network device for the terminal device for new beam monitoring from the pairs of TCI states configured by the network device for the terminal device for new beam monitoring. For example, the second signaling is a MAC CE or a DCI. For example, as shown in Table 1, the TCI states corresponding to the N new beams include eight pairs of TCI states.

[0371] Table 1

[0372] For example, as shown in Table 1, the sorting of the TCI states corresponding to the N new beams can be: the 1st downlink TCI state-the 1st uplink TCI state-the 2nd downlink TCI state-the 2nd uplink TCI state…-the 8th downlink TCI state-the 8th uplink TCI state.

[0373] 2、The P new beams are indicated by the TCI states corresponding to the P new beams, and the index of each new beam in the P new beams is indicated by the value of Z bits, and the value of the Z bits is used to indicate the TCI state corresponding to the new beam. Z = log2(R), and R is the number of TCI states in the N TCI states corresponding to the new beams, in which the associated reference signal is a downlink reference signal. R is less than or equal to N. Optionally, the downlink reference signals associated with the TCI states in which the associated reference signal is a downlink reference signal in the N TCI states corresponding to the new beams are all SSBs or CSI-RSs.

[0374] Optionally, the N TCI states corresponding to the new beams are TCI states activated or configured by the network device for the terminal device. In this implementation, some possible indication modes of the index of each new beam in the P new beams are introduced as follows.

[0375] Implementation one: the index of each new beam in the P new beams is indicated by the value of Z bits, and the 2 ZThe Z bits correspond to R TCI states, and the R TCI states are TCI states in which the associated reference signals corresponding to the N new beams are downlink reference signals. The value of the Z bits is 2 Z In the jth value of the Z bits, the value of the Z bits indicates the jth TCI state in the R TCI states. R is less than or equal to the number of TCI states corresponding to the N new beams. j is an integer greater than or equal to 1 and less than or equal to R.

[0376] In the jth value of the Z bits, the value of the Z bits indicates the jth TCI state in the R TCI states. R is less than or equal to the number of TCI states corresponding to the N new beams. j is an integer greater than or equal to 1 and less than or equal to R. X The values are sorted in ascending order or descending order. In one possible implementation, the R TCI states are sorted in ascending order of indexes or descending order of indexes. In another possible implementation, the R TCI states are sorted in ascending order of code points or descending order of code points.

[0377] In this implementation, if the terminal device adopts the common mode, the TCI states corresponding to the N new beams in the above implementation mode one are common TCI states. If the terminal device adopts the separate mode, the TCI states corresponding to the N new beams in the above implementation mode one are downlink TCI states or uplink TCI states.

[0378] In the jth value of the Z bits, the value of the Z bits indicates the jth TCI state in the R TCI states. R is less than or equal to the number of TCI states corresponding to the N new beams. j is an integer greater than or equal to 1 and less than or equal to R. Z The Z bits correspond to R TCI states, and the R TCI states are TCI states in which the associated reference signals corresponding to the N new beams are downlink reference signals. The value of the Z bits is 2 Z In the jth value of the Z bits, the value of the Z bits indicates the jth TCI state in the R TCI states. R is less than or equal to the number of TCI states corresponding to the N new beams. j is an integer greater than or equal to 1 and less than or equal to R.

[0379] In the jth value of the Z bits, the value of the Z bits indicates the jth TCI state in the R TCI states. R is less than or equal to the number of TCI states corresponding to the N new beams. j is an integer greater than or equal to 1 and less than or equal to R. X The values are sorted in ascending order or descending order. In this implementation, the terminal device adopts the separate mode. The R TCI states include uplink TCI states and downlink TCI states. Two possible sorting modes of the R TCI states are introduced as follows.

[0380] 1. The uplink TCI states in the R TCI states are arranged before or after the downlink TCI states in the R TCI states. The uplink TCI states in the R TCI states are sorted in ascending order of indexes or descending order of indexes. The downlink TCI states in the R TCI states are sorted in ascending order of indexes or descending order of indexes.

[0381] 2. The R TCI states are sorted in descending order or ascending order of the code points corresponding to the TCI states, and in the TCI states corresponding to the same code point, the uplink TCI state is arranged before or after the downlink TCI state.

[0382] In this implementation, the R TCI states include one or more pairs of TCI states, and each pair of TCI states has a corresponding code point. For the code point corresponding to each pair of TCI states, refer to the foregoing related description. Here, no longer described in detail.

[0383] It should be noted that the above is an example of indicating the technical solutions of the present application by the value of Z bits indicating the index of each new beam in the P new beams. In actual application, the index of each new beam in the P new beams can also be indicated by the value of X bits, wherein, Q is the number of TCI states corresponding to the N new beams. The value of X bits corresponds to the TCI state corresponding to the N new beams. For example, the value of X bits corresponds to the code point of the TCI state corresponding to the N new beams. When the value of X bits is the code point of the TCI state of the uplink reference signal, the value of X bits is meaningless.

[0384] 3. The P new beams are indicated by the reference signal associated with the TCI state corresponding to the P new beams or by the reference signal corresponding to the P new beams, and the reference signal associated with the TCI state corresponding to the N new beams or the reference signal corresponding to the N new beams includes L different downlink reference signals, L is an integer greater than or equal to 1, the index of each new beam in the P new beams is indicated by the value of Y bits, and the value of Y bits is used to indicate the reference signal associated with the TCI state corresponding to the new beam or the reference signal corresponding to the new beam,

[0385] The reference signal corresponding to the P new beams is configured by the network device for the terminal device.

[0386] Optionally, the TCI state corresponding to the N new beams is the TCI state activated or configured by the network device for the terminal device. In this implementation, some possible indication modes of the index of each new beam in the P new beams are introduced as follows.

[0387] Implementation one: the index of each new beam in the P new beams is indicated by the value of Y bits, and the value of Y bits is 2 Y values correspond to the L different downlink reference signals. When the value of Y bits is the a Y th value in the 2 Y values, the new beam indicated by the value of Y bits is the a

[0388] wherein, 2 Y The values are sorted in ascending order or descending order.

[0389] In a possible implementation, the L different downlink reference signals are sorted in ascending order of indexes of the downlink reference signals or in descending order of indexes of the downlink reference signals. For example, the reference signals corresponding to the N new beams of the network device include L different downlink reference signals (for example, SSB or CSI-RS), and the L bits are all 0, indicating that the reference signal corresponding to the downlink reference signal with the smallest index among the L different downlink reference signals.2 Y The values are sorted in ascending order or descending order. Y The values are sorted in ascending order or descending order. Y The L values are meaningless.

[0390] In another possible implementation, the L different downlink reference signals are sorted in ascending order of indexes of TCI states corresponding to the downlink reference signals or in descending order of indexes of TCI states corresponding to the downlink reference signals.

[0391] In another possible implementation, the L different downlink reference signals are sorted in ascending order of code points of TCI states corresponding to the downlink reference signals or in descending order of code points of TCI states corresponding to the downlink reference signals.

[0392] In this implementation, if the terminal device adopts the common mode, the TCI states corresponding to the N new beams in the above implementation one are common TCI states; if the terminal device adopts the separated mode, the TCI states corresponding to the N new beams in the above implementation one are uplink TCI states or downlink TCI states.

[0393] Implementation two: the index of each new beam in the P new beams is indicated by a value of Y bits, and the value of the Y bits is sorted in ascending order or descending order. Y The values are sorted in ascending order or descending order. Y When the a-th value of the values is taken, the new beam indicated by the value of the Y bits is the a-th downlink reference signal in the L different downlink reference signals. a is an integer greater than or equal to 1 and less than or equal to L-1. Y

[0394] wherein, 2 Y ​The values are sorted in ascending order or descending order. In this implementation, the terminal device adopts the separation mode. The following introduces two possible sorting orders of the L different downlink reference signals.

[0395] 1. The L different downlink reference signals are sorted in descending order or ascending order of the indexes of the downlink reference signals.

[0396] 2. The TCI states corresponding to the L different downlink reference signals include uplink TCI states and downlink TCI states. In the L different downlink reference signals, the downlink reference signals corresponding to the downlink TCI states are arranged before or after the downlink reference signals corresponding to the uplink TCI states; wherein the downlink reference signals corresponding to the downlink TCI states are sorted in descending order or ascending order of the indexes of the corresponding downlink TCI states. The downlink reference signals corresponding to the uplink TCI states are sorted in descending order or ascending order of the indexes of the corresponding uplink TCI states.

[0397] It should be noted that the above is an example of indicating the technical solution of the present application by the value of Y bits of the index of each new beam in P new beams. In actual application, the index of each new beam in P new beams can also be indicated by the value of X bits. Wherein, Q is the number of TCI states corresponding to the N new beams. The value of X bits corresponds to the TCI state corresponding to the N new beams. For example, the value of X bits corresponds to the code point corresponding to the TCI state of the associated reference signal. When the value of X bits is the code point of the TCI state of the uplink reference signal, the value of X bits is meaningless. For the code points corresponding to the multiple TCI states associated with the same downlink reference signal, when the value of X bits is the code point of any one of the multiple TCI states, the value of X bits indicates the downlink reference signal.

[0398] It should be noted that in addition to the above-mentioned manner, in actual application, the terminal device can also report the indexes of P new beams, or the indexes of the reference signals corresponding to P new beams.

[0399] In the embodiments of the present application, the terminal device determines reference signals corresponding to M serving beams and / or reference signals corresponding to N new beams. The N new beams are beams in the terminal device other than the M serving beams, M is an integer greater than or equal to 1, and N is an integer greater than or equal to 1. Then, the terminal device measures the reference signals corresponding to part or all of the M serving beams, and / or the terminal device measures the reference signals corresponding to part or all of the N new beams respectively, to obtain a first measurement result; and the terminal device determines whether at least one event of the terminal device occurs according to the first measurement result. The terminal device combines the first measurement result to monitor whether at least one event occurs, so as to trigger the reporting of the measurement result. This is beneficial to reduce unnecessary reporting of measurement results and avoid resource waste.
