[0002] The present application relates to the field of communication technology, in particular to a beam measurement and reporting 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 a short 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, forming a signal similar to a light beam (called analog beam, simply referred to as beam), thereby improving the transmission distance. Both network devices and terminal devices need to use beams for transmission. When the network device and the terminal device perform uplink and downlink data transmission, a specific beam needs to be used.

[0004] The network device and the terminal device can select a suitable beam through a beam management process. Then the network device and the terminal device communicate through the selected beam. The terminal device can also continue to measure the signal quality of multiple beams configured by the network device for the terminal device. Then, the terminal device reports the signal quality of at least one beam with good signal quality measured by the terminal device according to the reporting resource configured by the network. At present, the reporting of measurement results is mainly determined by the network device, which results in a large overhead of uplink resources. SUMMARY

[0005] The present application provides a beam measurement and reporting method and related apparatus, which is used for reporting the measurement result associated with the first event by the terminal device according to the reporting mode adopted by the terminal device when the first event occurs. Thus, the event-triggered measurement result reporting by the terminal device is realized. This is conducive to the terminal device reporting the measurement result on demand, avoiding unnecessary reporting of measurement results, and reducing the overhead of uplink resources.

[0006] The first aspect of the present application provides a beam measurement and reporting method, which can be used at the terminal side, 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, and the specific application does not make any limitation. It should be noted that in the present application, when referring to the terminal device, it can refer to the terminal device itself, or the chip, functional module, or integrated circuit in the terminal device that completes the method provided by the present application, and the specific application does not make any limitation. In the first aspect and its possible implementation manners, the method executed by the terminal device is taken as an example for description. The method comprises: measuring, by a terminal device, a serving beam and at least one new beam of the terminal device to obtain first measurement results, the at least one new beam being a beam other than the serving beam of the terminal device; and when a first event occurs, reporting, by the terminal device to a network device, measurement results corresponding to the first event according to a reporting mode adopted by the terminal device, the first event being that the signal quality of one or more new beams is higher than the signal quality of the serving beam by a first threshold value, the reporting mode adopted by the terminal device being mode one or mode two, and the measurement results associated with the first event belonging to the first measurement results.

[0007] In the above technical solution, when the first event occurs, the terminal device reports the measurement results associated with the first event according to the reporting mode adopted by the terminal device. Thus, the terminal device reports the measurement results based on event triggering. This is conducive to the terminal device reporting the measurement results on demand, avoiding unnecessary reporting of measurement results, and reducing the uplink resource overhead. Further, the terminal device reports the measurement results corresponding to the first event to the network device according to the reporting mode adopted by the terminal device. This is conducive to the terminal device reporting appropriate measurement results to the network device.

[0008] Based on the first aspect, in a possible implementation manner, mode one comprises that the reported measurement results corresponding to the first event include information of the serving beam by default, and mode two comprises that the reported measurement results corresponding to the first event optionally include information of the serving beam. This implementation manner illustrates the specific implementation of mode one and mode two, thereby facilitating the terminal device to report the measurement results by using the corresponding reporting mode. This is conducive to providing appropriate measurement results for the network device. It should be noted that mode one and mode two can also be other names, for example, mode one can also be referred to as reporting mode one, first mode, or first reporting mode, etc. Mode two can also be referred to as reporting mode two, second mode, or second reporting mode, etc.

[0009] Based on the first aspect, in a possible implementation manner, the information of the serving beam comprises at least one of the following: an index of the serving beam, a signal quality of the serving beam, or a difference between the signal quality of the serving beam and the signal quality of a new beam with the best signal quality.

[0010] In a possible implementation of the first aspect, the method further includes: receiving a reporting mode configured by the network device for the terminal device. The terminal device reports appropriate measurement results in combination with the reporting mode configured by the network device. Thus, the network device can make a decision on whether to update the serving beam of the terminal device in combination with the measurement results.

[0011] In a possible implementation of the first aspect, the network device configures a first parameter for the terminal device, where the first parameter is used to indicate one of the mode one and the mode two; or the terminal device receives configuration information 1 from the network device, where the configuration information 1 includes the first parameter, and the first parameter is used to indicate one of the mode one and the mode two; or the terminal device is configured with the first parameter, where the first parameter is used to indicate one of the mode one and the mode two; or

[0012] If the network device configures a second parameter for the terminal device, the terminal device adopts the mode one, and if the network device does not configure the second parameter for the terminal device, the terminal device adopts the mode two; or

[0013] If the terminal device is configured with the second parameter, the terminal device adopts the mode one, and if the terminal device is not configured with the second parameter, the terminal device adopts the mode two; or

[0014] If the network device configures a third parameter for the terminal device, the terminal device adopts the mode two, and if the network device does not configure the third parameter for the terminal device, the terminal device adopts the mode one; or

[0015] If the terminal device is configured with the third parameter, the terminal device adopts the mode two, and if the terminal device is not configured with the third parameter, the terminal device adopts the mode one.

[0016] It can be seen that several possible reporting mode configuration modes are exemplified, which is beneficial to implementation of the scheme.

[0017] In a possible implementation of the first aspect, when the terminal device adopts the reporting mode one, the measurement result corresponding to the first event includes at least one of the following: a signal quality of the serving beam, N resource indexes, or signal qualities of N new beams, the N resource indexes are resource indexes corresponding to the N new beams, the N new beams include part or all of the at least one new beam, and N is an integer greater than or equal to 1; or when the terminal device adopts the reporting mode two, the measurement result corresponding to the first event includes at least one of the following: first information, M resource indexes, or signal qualities of M beams, the first information is used to indicate whether the measurement result corresponding to the first event includes information of the serving beam, the M resource indexes are resource indexes corresponding to the M beams, the M beams include part or all of the at least one new beam, and M is an integer greater than or equal to 1.

[0018] In the implementation mode, the measurement result corresponding to the first event is illustrated in combination with the mode adopted by the terminal device. For mode one, the measurement result corresponding to the first event always includes the information of the serving beam. For mode two, the measurement result corresponding to the first event optionally includes the information of the serving beam. This is conducive to the terminal device reporting appropriate measurement results.

[0019] Based on the first aspect, in a possible implementation, if the M resource indexes include the resource index corresponding to the serving beam, the M beams include the serving beam; or if the M resource indexes do not include the resource index corresponding to the serving beam, the M beams do not include the serving beam. In this implementation, the terminal device and the network device know the value of the resource index corresponding to the serving beam, and it is determined whether the measurement result includes the information of the serving beam by judging whether the M resource indexes include the resource index corresponding to the serving beam.

[0020] Based on the first aspect, in a possible implementation, when the value of the first information is the first value, the M beams include the serving beam; or when the value of the first information is the second value, the M beams do not include the serving beam. In this implementation, whether the measurement result includes the information of the serving beam is indicated by the value of the first information. Another possible implementation of determining whether the measurement result includes the information of the serving beam is provided.

[0021] Based on the first aspect, in a possible implementation, when the reporting mode adopted by the terminal device is mode one, the measurement result corresponding to the first event is reported to the network device in the first format; wherein the first format includes at least one of the following: N resource index indication fields, N beam quality indication fields, or a serving beam quality indication field; wherein the N resource index indication fields are used to indicate the resource indexes corresponding to N new beams, the N resource index fields correspond to the N beam quality indication fields one by one, the N beam quality indication fields are used to indicate the signal quality of the N new beams, the serving beam quality indication field is used to indicate the signal quality of the serving beam, the N new beams are part or all of the at least one new beam, and N is an integer greater than or equal to 1; or,

[0022] when the reporting mode adopted by the terminal device is the second mode, the terminal device reports the measurement result corresponding to the first event to the network device in a second format; the second format comprises at least one of the following: a first information indication field, M resource index indication fields, or M beam quality indication fields; the first information indication field is used to indicate whether the second format comprises information of a serving beam, the M resource index indication fields are used to indicate resource indexes corresponding to M beams, the M resource index indication fields correspond to the M beam quality indication fields one by one, and the M beam quality indication fields are used to indicate signal qualities of the M beams; the M beams comprise part or all of the at least one new beam, and M is an integer greater than or equal to 1; or

[0023] when the reporting mode adopted by the terminal device is the second mode, the terminal device reports the measurement result corresponding to the first event to the network device in a third format; the third format comprises at least one of the following: M resource index indication fields, or M beam quality indication fields; the M resource index indication fields are used to indicate resource indexes corresponding to M beams, the M resource index indication fields correspond to the M beam quality indication fields one by one, and the M beam quality indication fields are used to indicate signal qualities of the M beams; the M beams comprise part or all of the at least one new beam, and M is an integer greater than or equal to 1.

[0024] In this implementation mode, for the first mode and the second mode, the terminal device reports the measurement result in an independent format respectively. This is conducive to the terminal device reporting appropriate measurement results in combination with the reporting mode.

[0025] Based on the first aspect, in a possible implementation mode, when the first information indication field indicates that the second format comprises information of a serving beam, a kth beam quality indication field in the M beam quality indication fields indicates a signal quality of the serving beam or indicates the signal quality of the serving beam, and k is an integer greater than or equal to 1 and less than or equal to M. In this implementation mode, when the second format comprises information of the serving beam, it is specified that the kth beam quality indication field indicates a signal quality of the serving beam or indicates the signal quality of the serving beam. This is conducive to the network device interpreting the measurement result.

[0026] Based on the first aspect, in a possible implementation mode, when the first information indication field indicates that the second format comprises information of a serving beam, a kth resource index indication field in the M resource index indication fields is meaningless, and k is an integer greater than or equal to 1 and less than or equal to M. For the case where the second format comprises information of the serving beam, the kth resource index indication field is meaningless. That is, the terminal device does not need to report a resource index corresponding to the serving beam.

[0027] In a possible implementation of the first aspect, when the first information indication field indicates that the second format does not include information of the serving beam, the kth resource index indication field of the M resource index indication fields indicates a resource index corresponding to one of the at least one new beam, and / or the kth beam quality indication field of the M beam quality indication fields indicates a signal quality of one new beam, k being an integer greater than or equal to 1 and less than or equal to M. If the second format does not include information of the serving beam, the kth resource index indication field and the kth beam quality indication field respectively indicate a resource index and a signal quality of the new beam. This facilitates the network device to interpret the measurement result.

[0028] In a possible implementation of the first aspect, if the resource indexes indicated by the M resource index indication fields include the resource index corresponding to the serving beam, the M beams include the serving beam; or if the resource indexes indicated by the M resource index indication fields do not include the resource index corresponding to the serving beam, the M beams do not include the serving beam. In this implementation, the network device and the terminal device can determine whether the measurement result includes information of the serving beam according to whether the M resource index indication fields include the resource index corresponding to the serving beam, in the case that the network device and the terminal device know the resource index corresponding to the serving beam. Thus, the network device can interpret the measurement result.

[0029] In a possible implementation of the first aspect, the terminal device reports the measurement result corresponding to the first event to the network device according to a reporting mode adopted by the terminal device, including: the terminal device reports the measurement result corresponding to the first event to the network device in a fourth format; the fourth format includes at least one of the following: a first information indication field, P resource index indication fields, P beam quality indication fields, or a serving beam quality indication field, the first information indication field is used to indicate whether the fourth format includes information of the serving beam, the P resource index indication fields are used to indicate resource indexes corresponding to P beams, the P resource index indication fields correspond to the P beam quality indication fields one by one, the P beam quality indication fields are used to indicate signal qualities of the P beams, the P beams include part or all of the at least one new beam; the serving beam quality indication field is used to indicate a signal quality of the serving beam, P being an integer greater than or equal to 1; or,

[0030] The terminal device reports the measurement result corresponding to the first event to the network device in a fifth format; the fifth format includes at least one of the following: R resource index indication fields, R beam quality indication fields, or a serving beam quality indication field, the R resource index indication fields are used to indicate resource indexes corresponding to R beams, the R resource index indication fields correspond to the R beam quality indication fields one by one, the R beam quality indication fields are used to indicate signal qualities of the R beams, the R beams include part or all of the new beams in the at least one new beam, R is an integer greater than or equal to 1, and the serving beam quality indication field is used to indicate a signal quality of a serving beam.

[0031] In this implementation mode, for mode one and mode two, the terminal device reports the measurement result in a unified format. Thus, multiple formats are avoided, and the scheme is simplified.

[0032] Based on the first aspect, in a possible implementation mode, when the reporting mode adopted by the terminal device is mode one, the fourth format does not include the first information indication field; when the reporting mode adopted by the terminal device is mode two, the fourth format does not include the serving beam quality indication field. Alternatively, when the reporting mode adopted by the terminal device is mode one, the first information indication field is meaningless; when the reporting mode adopted by the terminal device is mode two, the first information indication field is used to indicate whether the fourth format includes information of the serving beam. In this implementation mode, for different modes, some fields of the fourth format may not exist or may be meaningless. This facilitates the network device to interpret the measurement result.

[0033] Based on the first aspect, in a possible implementation mode, if the first information indication field indicates that the fourth format includes information of the serving beam, the s-th beam quality indication field in the P beam quality indication fields indicates or indicates a signal quality of the serving beam, s is an integer greater than or equal to 1 and less than or equal to P. In this implementation mode, it is specified that, in the case where the fourth format includes information of the serving beam, the s-th beam quality indication field indicates or indicates a signal quality of the serving beam. This facilitates the network device to interpret the measurement result.

[0034] Based on the first aspect, in a possible implementation mode, if the first information indication field indicates that the fourth format does not include information of the serving beam, the s-th resource index indication field in the P resource index indication fields is meaningless. In this implementation mode, for the case where the fourth format does not include information of the serving beam, the s-th resource index indication field can be ignored.

[0035] In a possible implementation of the first aspect, in a case where the first information indication field indicates that the fourth format does not include information of the serving beam, the s-th resource index indication field in the P resource index indication fields indicates a resource index corresponding to one of the at least one new beam, and / or the s-th beam quality indication field in the P beam quality indication fields indicates a signal quality of one of the new beams. In this implementation, in the case where the fourth format does not include information of the serving beam, the s-th resource index indication field and the s-th beam quality indication field respectively indicate a resource index corresponding to the new beam and a signal quality of the new beam.

[0036] In a possible implementation of the first aspect, in a case where the reporting mode adopted by the terminal device is mode one, the fifth format includes the serving beam quality indication field; in a case where the reporting mode adopted by the terminal device is mode two, the fifth format does not include the serving beam quality indication field; or, in a case where the reporting mode adopted by the terminal device is mode one, the serving beam quality indication field is used to indicate a signal quality of the serving beam; in a case where the reporting mode adopted by the terminal device is mode two, the serving beam quality indication field is meaningless. In this implementation, the fifth format includes some fields that may not exist or be meaningless for mode one and mode two, facilitating the network device to interpret the measurement result.

[0037] In a possible implementation of the first aspect, the first event includes event one and event two, the event one is that a signal quality of the serving beam is lower than a second threshold value, and the event two is that a signal quality of one or more new beams is higher than a signal quality of the serving beam by a first threshold value.

[0038] In a possible implementation of the first aspect, the method further includes: in a case where the first event is the event one, or in a case where the first event is the event two and the reporting mode adopted by the terminal device is mode one, the fifth format includes the serving beam quality indication field; in a case where the first event is the event two and the reporting mode adopted by the terminal device is mode two, the fifth format does not include the serving beam quality indication field. In this implementation, the condition under which the fifth format includes or does not include the serving beam quality indication field is specified, thereby facilitating the network device to interpret the measurement result.

[0039] In a possible implementation of the first aspect, in a case where the first event is the event one, the serving beam quality indication field is used to indicate a reference signal received power (RSRP) of the serving beam; or, in a case where the first event is the event two, the serving beam quality indication field is used to indicate a differential RSRP of the serving beam. In this implementation, the meaning of the serving beam quality indication field under different conditions is exemplified, thereby facilitating the network device to better interpret the serving beam quality indication field.

[0040] In a possible implementation of the first aspect, if the first event is event one, the length of the serving beam quality indication field is 7 bits; or if the first event is event two, the length of the serving beam quality indication field is 4 bits. In this implementation, the length of the serving beam quality indication field is specified under different conditions. This facilitates the network device in interpreting the serving beam quality indication field.

[0041] In a possible implementation of the first aspect, if the first event is event one, the serving beam quality indication field is used to indicate a first differential RSRP of the serving beam, and the first differential RSRP is a second threshold value minus the RSRP of the serving beam; or if the first event is event two, the serving beam quality indication field is used to indicate a second differential RSRP of the serving beam, and the signal quality of the R beams includes the RSRP of the R beams, and the second differential RSRP is the RSRP of a beam with the largest RSRP among the R beams minus the RSRP of the serving beam. Two calculation methods of the differential RSRP of the serving cell are provided, which enriches the implementation of the scheme. This is conducive to reducing the indication overhead of the terminal device.

[0042] In a possible implementation of the first aspect, if the resource index indicated by the R resource index indication fields includes the resource index corresponding to the serving beam, the R beams include the serving beam; or if the resource index indicated by the R resource index indication fields does not include the resource index corresponding to the serving beam, the R beams do not include the serving beam. In this implementation, the terminal device and the network device know the value of the resource index corresponding to the serving beam, and the R resource index indication fields are used to determine whether the measurement result includes the information of the serving beam.

[0043] In a possible implementation of the first aspect, the method further includes: the terminal device sends, to the network device, capability information, and the capability information includes at least one of the following: whether the terminal device supports triggering the measurement result of the beam, the number of beams supported by the terminal device for reporting, or information of a reporting mode supported by the terminal device. This facilitates the network device in configuring a suitable reporting mode for the terminal device.

[0044] In a possible implementation of the first aspect, the information of the reporting mode supported by the terminal device includes at least one of the following: the reporting mode supported by the terminal device, information of whether the terminal device supports mode one, information of whether the terminal device supports mode two, the number of reporting modes supported by the terminal device, or whether the terminal device supports mode one and mode two simultaneously.

[0045] In a possible implementation manner of the first aspect, if the terminal device supports reporting of measurement results of triggered beams, it indicates that the terminal device supports mode one; or if the terminal device supports reporting of measurement results of triggered beams, it indicates that the terminal device supports mode two.

[0112] The communication system to which the present application is applicable includes a terminal device and a network device. The terminal device and the network device are introduced as follows.

[0113] Terminal device, also known as UE, mobile station (MS), mobile terminal (MT), fixed wireless access (FWA), customer premise equipment (CPE), etc. The terminal device is a device including a 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, the terminal device can include: mobile phone, tablet computer, notebook computer, palm computer, mobile internet device (MID), wearable device, virtual reality (VR) device, augmented reality (AR) device, wireless terminal in industrial control, wireless terminal in self driving (for example, unmanned aerial vehicle, vehicle), wireless terminal in remote medical surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, or wireless terminal in smart home, etc. For example, the wireless terminal in self driving can be unmanned aerial vehicle, helicopter, or airplane, etc. For example, the wireless terminal in Internet of Vehicles can be vehicle-mounted device, whole vehicle device, vehicle-mounted module, vehicle, or ship, etc. The wireless terminal in industrial control can be camera, robot, or mechanical arm, etc. The wireless terminal in smart home can be television, air conditioner, sweeping machine, sound box, or set top box, etc. The terminal device can also be a device or module with corresponding communication function accessing the above-mentioned communication system. The terminal device is usually provided with a communication module, circuit or chip for executing corresponding communication function, and is also configured with program instructions for executing corresponding communication function.

[0114] 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 device or apparatus, which is not limited in the present application. It should be noted that in the present application, when referring to the terminal device, it can refer to the terminal device itself, or the chip, functional module or integrated circuit in the terminal device for completing the method provided in the present application, which is not limited in the present application.

[0115] 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.

[0116] 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.

[0117] 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).

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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 (Higher PHY) layer, 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.

[0125] 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, a remote radio head (RRH), or other similar functional entity in 3GPP. 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, and other processing functions. The RU communicates with one or more UEs over a wireless link.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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 devices 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.

[0130] In order to facilitate understanding of the technical solutions of the embodiments of the present application, two possible communication systems to which the method provided by the embodiments of the present application is applicable are shown in FIGS. 3 and 4.

As shown in FIG. 3, the communication system includes at least one network device and at least one terminal device. For example, as shown in FIG. 3, the network device 311, the terminal device 321 and the terminal device 322. The network device 311 can perform transmission with the terminal device 321 and the terminal device 322. The network device 311 and the terminal device 321 or the terminal device 322 can perform the technical solutions of the present application.

[0132] FIG. 4 is another schematic diagram of a communication system according to an embodiment of the present application. As shown in FIG. 4, the communication system can include at least two network devices and at least one terminal device. For example, as shown in FIG. 4, the network device 411, the network device 412, the network device 413 and the terminal device 421. The terminal device 421 can be provided with communication services by multiple network devices. For example, as shown in FIG. 4, the network device 411 can perform transmission with the terminal device 421, the network device 412 can perform transmission with the terminal device 421. The network device 413 can perform transmission with the terminal device 421. That is, one terminal device can be simultaneously provided with communication services by multiple network devices. The terminal device 421 and the network device 411, the network device 412 or the network device 413 can perform the technical solutions of the present application.

[0133] In order to facilitate understanding of the technical solutions of the present application, some technical terms related to the present application are introduced below.

[0134] 1. Beam: A beam is a kind of communication resource. A beam can be a wide beam, or a narrow beam, or other types of beams, and the technology to form a beam can be beamforming technology or other technology means. The beamforming technology can be digital beamforming technology, analog beamforming technology, and hybrid digital / analog beamforming technology. Different beams can be considered as different resources.

[0135] A beam can be referred to as a spatial domain filter, a spatial filter, a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, quasi-colocation (QCL) information, a QCL assumption, or a QCL indication in the NR protocol. A beam can be indicated by a transmission configuration indicator state (TCI-state) parameter or a spatial relation parameter. Therefore, in this application, a beam can be replaced by a spatial domain filter, a spatial filter, a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, QCL information, a QCL assumption, a QCL indication, a TCI-state (including uplink TCI-state and downlink TCI-state), or a spatial relation, etc. The above terms are also equivalent to each other. A beam can also be replaced by other terms representing a beam, which are not limited in this application.

[0136] A beam used for transmitting a signal can be referred to as a transmission beam (Tx beam), a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, a spatial transmission parameter, a spatial domain transmission setting, or a spatial transmission setting. The transmission beam can also be referred to as a downlink beam. In this application, the transmission beam, the downlink beam, the channel state information reference signal (CSI-RS), the TCI State, the downlink / joint transmission configuration indication state (DL or joint TCI state), the synchronization signal and PBCH block (SS / PBCH, referred to as SSB), and the tracking reference signal (TRS) can be replaced with each other.

[0137] A beam for receiving a signal can be referred to as a reception beam (Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, a spatial domain reception setting, or a spatial reception setting. An uplink transmission beam can be indicated by any one of a spatial relationship, an uplink TCI-state, a sounding reference signal (SRS) resource (indicating a transmission beam using the SRS). A reception beam can also be referred to as an uplink beam. In this application, a reception beam, an uplink beam, an uplink transmission configuration indication state (UL TCI state), a DL or joint TCI state, an SRS, a CSI-RS, an SSB, and a TRS can be replaced with each other.

[0138] A transmission beam can refer to a distribution of signal strength in different directions in space after a signal is transmitted by an antenna, and a reception beam can refer to a distribution of signal strength in different directions in space of a wireless signal received by an antenna.

[0139] In addition, a beam can be a wide beam, or a narrow beam, or other types of beams. The technology for forming a beam can be beamforming technology or other technology. The beamforming technology can be digital beamforming technology, analog beamforming technology, hybrid digital beamforming technology, or hybrid analog beamforming technology, etc.

[0140] 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 through 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 TCI (Transmission Configuration Indication) field in the downlink control information (DCI). In this application, a beam can be replaced by a resource.

[0141] 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.

[0142] 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.

[0143] 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 the appropriate 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.

[0144] In the 3GPP protocol, the network device can indicate the TCI state to the terminal device through the TCI field in the downlink control information (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 ID 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.

[0145] 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:

[0146] 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 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:

[0147] 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.

[0148] 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:

[0149] The specific execution steps are as follows:

[0150] 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.

[0151] The configuration, activation and indication of the TCI state are introduced below.

[0152] 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.

[0153] TCI-state activation: after the network device configures multiple TCI-states, it needs to activate 8 of them through a media or 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.

[0154] 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.

[0155] 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. In this paper, ID can be the abbreviation of any one of identifier, indication, indicator, index, identity, identification, and identifier, indication, indicator, index, identity, identification can be replaced with each other.

[0156] 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 are introduced as follows.

[0157] Stage one: coarse beam alignment between the network device and the terminal device.

[0158] 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 reception beams, 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 a beam for the base station to transmit signals and a 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 a base station beam, and the beam for the terminal device to receive signals is referred to as a terminal beam.

[0159] 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 B5, 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 the corresponding SSB resources using the beam B0, transmits SSBs to the terminal device using the beam B1, and so on, and transmits SSBs to the terminal device using the beam B5. The terminal device measures the SSBs transmitted by the base station through the beams B0 to B5 respectively through the beams U0 to U3 respectively, and obtains measurement results. The terminal device can determine a 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 stage one, the base station beam and the terminal beam can be understood as wide beams.

[0160] Stage two: base station beam fine adjustment.

[0161] 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.

[0162] Stage three: UE beam refinement.

[0163] 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.

[0164] 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.

[0165] 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 periodic measurement reference signals for the terminal device. The terminal device can measure the periodic measurement reference signals based on the reference signal resource configuration information, and periodically report measurement results. Optionally, the measurement results obtained by the terminal device for the periodic measurement reference signals can be carried on a physical uplink control channel (PUCCH) resource.

[0166] Semi-persistent reporting: the terminal device measures periodic reference signals, but reports 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 periodic measurement reference signals for the terminal device. When the terminal device receives activation signaling (for example, MAC CE or DCI) from the network device, the terminal device can continuously report measurement results. Of course, the network device can also send deactivation instructions 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 signal and the reporting of the measurement results are semi-persistent. When the terminal device receives activation signaling from the network device, the terminal device continuously measures the reference signal and reports the measurement results. When the terminal device receives deactivation instructions from the network device, the terminal device stops reporting the measurement results. In addition, the measurement results can be carried on a PUCCH resource or a physical uplink shared channel (PUSCH) resource.

[0167] Aperiodic reporting: when the terminal device receives a trigger instruction (for example, DCI) from the network device, the terminal device measures the reference signal and reports the measurement results. After completing the reporting, the terminal device stops reporting the measurement results. Optionally, the reference signal can be a periodic reference signal, a semi-persistent reference signal, or an aperiodic reference signal. Optionally, the measurement results are carried on a PUSCH resource.

[0168] The network device is dominant in the measurement result reporting procedure of the terminal device before R18 and R18, 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), and therefore the uplink resource is wasted. In R19, event-triggered reporting is introduced, and the terminal device can report the beam measurement result related to the event. Therefore, how to trigger the measurement result reporting is a problem worth considering.

[0169] The present application provides corresponding technical solutions, which are used for reporting the measurement result associated with the first event by the terminal device according to the reporting mode adopted by the terminal device when the first event occurs. Thus, the terminal device reports the measurement result based on the event triggering. This is conducive to the terminal device reporting the measurement result on demand, avoiding unnecessary reporting of the measurement result, and reducing the uplink resource overhead.

[0170] 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.

[0171] In the present application, optionally, the signal quality can be RSRP, signal to interference plus noise ratio (SINR), layer 1 reference signal received power (L1-RSRP), layer 1 signal to interference plus noise ratio (L1-SINR), synchronization signal reference signal received power (SS-RSRP), channel state information reference signal received power (CSI-RSRP), synchronization signal signal-to-interference-plus-noise ratio (SS-SINR), or channel state information signal to interference plus noise ratio (CSI-SINR), and the present application is not limited in particular.

[0172] The technical solutions of the present application will be described below in conjunction with specific embodiments.

[0173] In the present application, the serving beam can also be referred to as: TCI state, serving beam measurement resource, reference signal resource, first beam measurement resource, first measurement resource, or resource corresponding to the serving beam, and the present application is not limited in particular. The new beam can also be referred to as: TCI state, new beam measurement resource, reference signal resource, second beam measurement resource, second measurement resource, or resource corresponding to the new beam, and the present application is not limited in particular.

[0174] FIG. 8 is a schematic diagram of one embodiment of the beam measurement and reporting method of the present application. Please refer to FIG. 8, the method comprises:

[0175] 801. The terminal device measures the serving beam and at least one new beam of the terminal device to obtain a first measurement result.

[0176] The serving beam is a beam currently used by the terminal device and the network device for transmission. Optionally, the serving beam is a beam corresponding to a TCI state indicated by the network device for the terminal device. Alternatively, the serving beam is a beam corresponding to a QCL resource in the TCI state indicated by the network device for the terminal device, or the serving beam is a beam corresponding to an SSB resource corresponding to the QCL resource in the TCI state indicated by the network device for the terminal device.

[0177] The SSB resource corresponding to the QCL resource in the TCI state indicated by the network device for the terminal device can be understood as an SSB resource having a QCL relationship with the QCL resource. For example, the SSB resource is a source QCL resource in a QCL chain, and the source QCL resource is an SSB resource. The QCL chain is determined according to the QCL resource in the TCI state indicated by the network device for the terminal device. For example, the QCL resource in 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 TRS resource. The TCI state corresponding to the CSI-RS resource can be understood as a TCI state adopted by the network device for transmitting the CSI-RS resource, or a TCI state adopted by the network device for transmitting a 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 a TCI state adopted by the network device for transmitting the TRS resource, or a TCI state adopted by the network device for transmitting a TRS corresponding to the TRS. Therefore, the QCL resource in the TCI state indicated by the network device for the terminal device (such as a CSI-RS resource), the QCL resource in the TCI state corresponding to the CSI-RS resource (such as a TRS resource), and the QCL resource in the TCI state corresponding to the TRS resource (such as an SSB resource) form a QCL chain. The source QCL resource of the QCL chain is an SSB resource. That is, the SSB resource associated with the QCL resource in the TCI state indicated by the network device for the terminal device.

[0178] In a possible implementation, the at least one new beam is a beam of the terminal device other than the serving beam, or in other words, the at least one new beam is a beam of the terminal device distinguished from the serving beam. For example, the at least one new beam can be understood as a candidate beam of the terminal device. For example, the at least one new beam is a beam corresponding to a TCI state other than a TCI state indicated for the terminal device in TCI states configured by the network device for the terminal device. For another example, the at least one new beam is a beam corresponding to a new beam measurement resource configured by the network device for the terminal device. The serving beam and the at least one new beam are configured by the network device for the terminal device for a same measurement reporting process or a same measurement reporting configuration. Measurement resources corresponding to the serving beam and the at least one new beam can be configured in a same resource set. Therefore, the at least one new beam is referred to as at least one new beam corresponding to the serving beam. The terminal device measures the serving beam and the at least one new beam. A resource type corresponding to the serving beam is same as a resource type corresponding to the at least one new beam. For example, a resource corresponding to the serving beam is an SSB resource, and a resource corresponding to the at least one new beam is an SSB resource. For another example, a resource corresponding to the serving beam is a CSI-RS resource, and a resource corresponding to the at least one new beam is a CSI-RS resource.

[0179] In another possible implementation, the at least one new beam is a beam of the terminal device other than the first activated beam. Or in other words, the at least one new beam is a beam of the terminal device distinguished from the first activated beam. For example, the at least one new beam can be a beam other than the first activated beam activated by the network device for the terminal device. Optionally, the first activated beam can or can not be a serving beam of the terminal device. When the network device indicates the first activated beam as the serving beam of the terminal device, the first activated beam is the serving beam.

[0180] Optionally, the first measurement result includes a measurement result of the serving beam and / or a measurement result of the at least one new beam. For example, the first measurement result includes at least one of the following: a signal quality of the serving beam, a signal quality of the at least one new beam, a signal quality difference between the at least one new beam and the serving beam, an index of the serving beam, or an index of the at least one new beam.

[0181] It should be noted that if the terminal device performs transmission with multiple TRPs, the terminal device includes multiple serving beams, and the multiple serving beams correspond to the multiple TRPs in a one-to-one manner.

[0182] It should be noted that the signal quality of the beam can also be referred to as the beam quality. That is, in this application, the signal quality and the beam quality are equivalent.

[0183] It should be noted that, optionally, the resource corresponding to the serving beam and the resource corresponding to the at least one new beam can belong to the same resource set. The resource set can be referred to as a new beam resource set, or a beam resource set, which is not limited in this application. Alternatively, the resource corresponding to the serving beam and the resource corresponding to the at least one new beam can also belong to different resource sets.

[0184] Optionally, the resource corresponding to the serving beam is a QCL resource in the TCI state indicated by the network device for the terminal device. Alternatively, the resource corresponding to the serving beam is an SSB resource corresponding to the QCL resource in the TCI state indicated by the network device for the terminal device. Alternatively, the resource corresponding to the serving beam is a serving beam measurement resource configured by the network device for the terminal device.

[0185] Optionally, the resource corresponding to the at least one new beam is a QCL resource in the TCI state configured or activated by the network device for the terminal device, except for the TCI state indicated by the network device for the terminal device. Alternatively, the resource corresponding to the at least one new beam is an SSB resource corresponding to the QCL resource in the TCI state configured or activated by the network device for the terminal device, except for the TCI state indicated by the network device for the terminal device. Alternatively, the resource corresponding to the at least one new beam is a new beam measurement resource configured by the network device for the terminal device.

[0186] 802. When the first measurement result represents the occurrence of the first event, the terminal device reports the measurement result corresponding to the first event to the network device according to the reporting mode adopted by the terminal device.

[0187] The first event is that the signal quality of the one or more new beams is higher than the signal quality of the serving beam by a first threshold value. Alternatively, the first event is that the difference between the signal quality of the one or more new beams and the signal quality of the serving beam is greater than or equal to a first threshold value. Alternatively, the first event is that the difference between the signal quality of the one or more new beams and the signal quality of the serving beam is greater than a first threshold value. The first threshold value is preconfigured, reported by the terminal device, or specified by a communication protocol, which is not limited in this application. In this application, the terms 'high', 'greater than', or 'greater than or equal to' can be replaced with each other. In this application, the terms 'low', 'less than', or 'less than or equal to' can be replaced with each other.

[0188] Optionally, the first event can also be that the signal quality of the serving beam is lower than a first threshold value. The first threshold value is preconfigured, reported by the terminal device, or specified by a communication protocol, which is not limited in this application.

[0189] The signal quality of the serving beam being lower than the first threshold can be referred to as event one. The signal quality of the one or more new beams being higher than the signal quality of the serving beam by the first threshold can be referred to as event two.

[0190] It should be noted that the first threshold in event one and the first threshold in event two are generic thresholds. The first threshold in event one and the first threshold in event two can be the same or can be different.

[0191] The first event can be one of event one or event two. Or the first event includes event one and event two.

[0192] The measurement result corresponding to the first event is the measurement result associated with the first event. The measurement result can be referred to as a measurement result report, an event triggered or UE initiated measurement result report, an event triggered or UE initiated CSI report, a CSI report, an event triggered or UE initiated beam measurement result report, a beam measurement result report, an event triggered or UE initiated interference measurement report, or an interference measurement report, without limitation. As an example, event triggering, event occurrence can also be referred to as UE triggering, or UE initiated, etc. For example, the measurement result associated with the first event includes at least one of the following: the signal quality of the serving beam, the signal quality of the one or more new beams, the index of the serving beam, the index of the one or more new beams, or the signal quality difference between the one or more new beams and the serving beam.

[0193] The reporting mode adopted by the terminal device is mode one or mode two. Mode one includes that the measurement result corresponding to the first event reported by the terminal device includes the information of the serving beam by default. That is, when the first event occurs, the terminal device will always report the information of the serving beam. Mode two includes that the measurement result corresponding to the first event reported by the terminal device optionally includes the information of the serving beam. That is, the measurement result associated with the first event can or can not include the information of the serving beam, and whether to report the information of the serving beam is determined by the terminal device. The information of the serving beam includes at least one of the following: the index of the serving beam, the signal quality of the serving beam, or the signal quality difference between the serving beam and the new beam with the best signal quality. It should be noted that mode one can also be referred to as reporting mode one, first reporting mode, or first mode, etc. The name of mode one is not limited in the present application. Mode two can also be referred to as reporting mode two, second reporting mode, or second mode, etc. The name of mode two is not limited in the present application.

[0194] For example, the first measurement result includes the signal quality of the serving beam and the signal quality of the at least one new beam. When the signal quality of one or more new beams in the at least one new beam is higher than the signal quality of the serving beam by a first threshold value, it indicates that the first event occurs. The terminal device reports the measurement result corresponding to the first event to the network device according to the reporting mode adopted by the terminal device.

[0195] In a possible implementation, when the reporting mode adopted by the terminal device is mode one, the measurement result corresponding to the first event includes at least one of the following: the signal quality of the serving beam, N resource indexes, or the signal quality of N new beams. The N resource indexes are resource indexes corresponding to the N new beams. The N new beams include some or all of the at least one new beam. N is an integer greater than or equal to 1. Therefore, when the terminal device reports the measurement result corresponding to the first event in mode one, the measurement result corresponding to the first event includes the information of the serving beam by default, or the measurement result corresponding to the first event always includes the information of the serving beam.

[0196] It should be noted that the value of N can be reported by the terminal device, or be specified by a communication protocol, or be configured by the network device for the terminal device. For example, the terminal device reports the maximum number of new beams that the terminal device supports to report, that is, the maximum value of N, through capability information. The network device configures a specific value of N for the terminal device, and the specific value cannot exceed the maximum value of N. For example, the network device can configure any value in N={1, 2, 3, 4} for the terminal device. When the value of N is not configured, a default value, such as 1, can be used.

[0197] It should be noted that the above is a possible example of the measurement result corresponding to the first event. In actual application, the measurement result corresponding to the first event can include at least one of the following: the signal quality of the serving beam, the N resource indexes, or the differential quality of the N new beams. The differential quality of the N new beams refers to the difference between the signal quality of each new beam and the signal quality of the serving beam. For example, the terminal device quantifies the signal quality of the serving beam by X (e.g., X = 7) bits, and quantifies the differential quality of each new beam by Y (e.g., Y = 4) bits. Alternatively, the measurement result corresponding to the first event includes at least one of the following: the signal quality of the serving beam or the differential quality of the serving beam, the N resource indexes, the signal quality of the new beam with the best signal quality among the N new beams, or the differential quality of the new beams other than the new beam with the best signal quality among the N new beams. The differential quality of the new beams other than the new beam with the best signal quality among the N new beams refers to the difference between the signal quality of each new beam and the signal quality of the new beam with the best signal quality. Thus, the overhead of the terminal device reporting the measurement result is reduced. The differential quality of the serving beam refers to the difference between the signal quality of the serving beam and the signal quality of the new beam with the best signal quality, such as differential quality of the serving beam = signal quality of the new beam with the best signal quality - signal quality of the serving beam. The differential quality of the serving beam can also refer to the difference between the signal quality of the serving beam and (signal quality of the new beam with the best signal quality - first threshold value), such as differential quality of the serving beam = (signal quality of the new beam with the best signal quality - first threshold value) - signal quality of the serving beam.

[0198] In another possible implementation, when the terminal device adopts the reporting mode two, the measurement result corresponding to the first event includes at least one of the following: the first information, the M resource indexes, or the signal quality of the M beams. The first information is used to indicate whether the measurement result corresponding to the first event includes the information of the serving beam. The M resource indexes are the resource indexes corresponding to the M beams. The M beams include part or all of the at least one new beam. The M beams can also include the serving beam. M is an integer greater than or equal to 1. Thus, it can be known that when the terminal device adopts the reporting mode two to report the measurement result corresponding to the first event, the measurement result corresponding to the first event optionally includes the information of the serving beam. The first information can be used to indicate whether the measurement result corresponding to the first event includes the information of the serving beam.

[0199] It should be noted that the value of M can be reported by the terminal device, or be specified by the communication protocol, or be configured by the network device for the terminal device. For example, the terminal device reports the maximum number of beams that the terminal device supports to report, i.e., the maximum value of M. The network device configures the specific value of M for the terminal device, which does not exceed the maximum value of M. For example, the network device can configure the terminal device with any value in M={1, 2, 3, 4}. Optionally, it can also be specified that the value of M is at least 2, i.e., M=1 cannot be configured. For example, the network device can configure the terminal device with any value in M={2, 3, 4}. This is to avoid that when M=1, if the signal quality information of the serving beam is included in the measurement result, the signal quality information of the new beam cannot be included. When the value of M is not configured, a default value can be used, such as the default value 2. The default value is 2, which is to ensure that when the signal quality information of the serving beam is included in the measurement result, the signal quality information of at least one new beam can also be included. The signal quality information of the serving beam can include the signal quality of the serving beam and / or the corresponding resource index of the serving beam. The signal quality information of the new beam can include the signal quality of the new beam and / or the corresponding resource index of the new beam.

[0200] It should be noted that the above is another possible example of the measurement result corresponding to the first event. In actual application, the measurement result corresponding to the first event can include at least one of the following: the first information, the M resource indexes, the signal quality of the beam with the best signal quality among the M beams, or the differential quality of the beams other than the beam with the best signal quality among the M beams. The differential quality of the beams other than the beam with the best signal quality among the M beams refers to the difference between the signal quality of each of the beams other than the beam with the best signal quality among the M beams and the signal quality of the beam with the best signal quality, thereby reducing the overhead of the terminal device reporting the measurement result. For example, the terminal device quantizes the signal quality of the beam with the best signal quality among the M beams by X (e.g., X=7) bits, and quantizes the differential quality of each of the beams other than the beam with the best signal quality among the M beams by Y (e.g., Y=4) bits.

[0201] Optionally, for the new beam included in the measurement result corresponding to the first event, the measurement result corresponding to the first event can also include an indication information, which is used to indicate whether the signal quality of the new beam is better than the signal quality of the serving beam, or whether the signal quality of the new beam is higher than the signal quality of the serving beam by a certain degree, such as the signal quality of the new beam minus the signal quality of the serving beam being greater than a first threshold. Optionally, it can be further limited that the indication information is included in the measurement result corresponding to the first event only when mode two is adopted. When mode one is adopted, the indication information is not included in the measurement result corresponding to the first event.

[0202] Optionally, the reporting of the signal quality of the serving beam adopts a first step size. The network device can calculate the signal quality of the serving beam through the first step size and the value indicated by the serving beam quality indication field. For example, the signal quality of the serving beam = the first step size * the value indicated by the serving beam quality indication field. For another example, the signal quality of the serving beam = the first step size * the value indicated by the serving beam quality indication field + the signal quality of the new beam with the best signal quality.

[0203] Optionally, the reporting of the signal quality of the new beam adopts a second step size. The network device can calculate the signal quality of the new beam through the second step size and the value indicated by the new beam quality indication field. For example, the signal quality of the new beam = the second step size * the value indicated by the new beam quality indication field. For another example, the signal quality of the new beam = the second step size * the value indicated by the new beam quality indication field + the signal quality of the new beam with the best signal quality.

[0204] It can be specified that the first step size and the second step size are different. For example, it is specified that the first step size is greater than the second step size, so that the range of the signal quality that can be indicated by the serving beam quality indication field is larger.

[0205] In this implementation, the network device can determine whether the measurement result corresponding to the first event includes the information of the serving beam through the following two possible implementation manners.

[0206] Implementation manner one: if the resource index corresponding to the serving beam is included in the M resource indexes, the M beams include the serving beam. If the resource index corresponding to the serving beam is not included in the M resource indexes, the M beams do not include the serving beam. That is, the network device determines whether the M beams include the serving beam according to whether the resource index corresponding to the serving beam is included in the M resource indexes.

[0207] Implementation manner two: when the value of the first information is a first value, the M beams include the serving beam. Or, when the value of the first information is a second value, the M beams do not include the serving beam. That is, the network device can determine whether the M beams include the serving beam through the first information. For example, the value of the first information is 0, which indicates that the M beams include the serving beam. The value of the first information is 1, which indicates that the M beams do not include the serving beam. For another example, the value of the first information is true, which indicates that the M beams include the serving beam. The value of the first information is false, which indicates that the M beams do not include the serving beam.

[0208] Implementation manner three: if the resource corresponding to the serving beam and the resource corresponding to the new beam are configured in the same resource set, the implementation manner one is adopted to determine whether the measurement result corresponding to the first event includes the information of the serving beam; otherwise, the implementation manner two is adopted to determine whether the measurement result corresponding to the first event includes the information of the serving beam. In other words, if the resource corresponding to the serving beam and the resource corresponding to the new beam are configured in the same resource set, whether the M beams include the serving beam is determined by whether the resource index corresponding to the serving beam is included in the M resource indexes, and the first information indication field does not exist. If the resource corresponding to the serving beam is not configured in the same resource set as the resource corresponding to the new beam, that is, the resource corresponding to the serving beam is not in the same resource set as the resource corresponding to the new beam, the first information indication field exists, and the first information indication field is used to indicate whether the M beams include the serving beam.

[0209] Implementation manner four: the serving beam is represented by a special resource index. If the special resource index is included in the M resource indexes, the M beams include the serving beam. The special resource index can be an index of all 0s, such as 000000 (binary), or an index of all 1s, such as 111111 (binary).

[0210] It can be further specified that if the resource corresponding to the serving beam and the resource corresponding to the new beam are not configured in the same resource set, the implementation manner four is adopted to determine whether the measurement result corresponding to the first event includes the information of the serving beam. If the resource corresponding to the serving beam and the resource corresponding to the new beam are configured in the same resource set, the implementation manner one is adopted to determine whether the measurement result corresponding to the first event includes the information of the serving beam.

[0211] In a possible implementation manner, for the mode one and the mode two, the terminal device reports the measurement result corresponding to the first event in an independent format respectively. The following introduces several possible reporting formats.

[0212] I. When the reporting mode adopted by the terminal device is the mode one, the terminal device reports the measurement result corresponding to the first event to the network device in the first format.

[0213] The first format includes at least one of the following: N resource index indication fields, N beam quality indication fields, or a serving beam quality indication field. The N resource index indication fields are used to indicate resource indexes corresponding to N new beams. That is, the N resource index indication fields correspond to the N new beams one by one, and each resource index indication field is used to indicate a resource index corresponding to a new beam corresponding to the resource index indication field. The N beam quality indication fields are used to indicate signal qualities of the N new beams. That is, the N beam quality indication fields correspond to the N new beams one by one, and each beam quality indication field is used to indicate a signal quality of a new beam corresponding to the beam quality indication field. The N new beams are part or all of the at least one new beam. N is an integer greater than or equal to 1. The serving beam quality indication field is used to indicate a beam quality of a serving beam. For example, the first format can be represented as shown in Table 1:

[0214] Table 1

[0215] It should be noted that the serving beam quality indication field can be the last field in the first format, or the first field in the first format. Alternatively, the serving beam quality indication field can be a field next to the Nth beam quality indication field in the first format, or the serving beam quality indication field can be a field before the first resource index indication field.

[0216] It should be noted that the signal quality of the serving beam and the signal qualities of the N new beams indicated in the above format can be represented in a differential manner. For example, the reporting format includes the signal quality of the serving beam and the differential qualities of the N new beams. The differential qualities of the N new beams refer to the differences between the signal qualities of the N new beams and the signal quality of the serving beam, respectively. For another example, the reporting format includes the differential quality of the serving beam, the signal quality of a new beam with the best signal quality among the N new beams, and the differential qualities of the new beams other than the new beam with the best signal quality among the N new beams. The differential qualities of the new beams other than the new beam with the best signal quality among the N new beams refer to the differences between the signal qualities of the new beams other than the new beam with the best signal quality among the N new beams and the signal quality of the new beam with the best signal quality, respectively. The differential quality of the serving beam refers to the difference between the signal quality of the serving beam and the signal quality of the new beam with the best signal quality, such as differential quality of the serving beam = signal quality of the new beam with the best signal quality - signal quality of the serving beam. The differential quality of the serving beam can also refer to the difference between the signal quality of the serving beam and (signal quality of the new beam with the best signal quality - a first threshold value), such as differential quality of the serving beam = (signal quality of the new beam with the best signal quality - the first threshold value) - signal quality of the serving beam.

[0217] It should be noted that the first format can also include other fields. For example, the first format can also include a resource index indication field corresponding to the service beam.

[0218] II. When the reporting mode adopted by the terminal device is mode II, the terminal device reports the measurement result corresponding to the first event to the network device in a second format.

[0219] The second format includes at least one of the following: a first information indication field, M resource index indication fields, or M beam quality indication fields. M is an integer greater than or equal to 1. The first information indication field is used to indicate whether the second format includes information of the service beam. The information of the service beam is described above. The M resource index indication fields are used to indicate resource indexes corresponding to the M beams. That is, the M resource index indication fields correspond to the M beams one by one, and each resource index indication field is used to indicate a resource index corresponding to the beam corresponding to the resource index indication field. The M beam quality indication fields are used to indicate signal qualities of the M beams. That is, the M beam quality indication fields correspond to the M beams one by one, and each beam quality indication field is used to indicate a signal quality of the beam corresponding to the beam quality indication field. For example, the second format can be as shown in Table 2:

[0220] Table 2

[0221] Optionally, when the first information indication field indicates that the second format includes information of the service beam, the kth beam quality indication field in the M beam quality indication fields indicates the signal quality of the service beam or indicates the signal quality of the service beam. k is an integer greater than or equal to 1 and less than or equal to M. For example, k = 1, or k = M.

[0222] Optionally, when the first information indication field indicates that the second format includes information of the service beam, the kth resource index indication field in the M resource index indication fields is meaningless, and the network device can ignore the kth resource index indication field. k is an integer greater than or equal to 1 and less than or equal to M. For example, k = 1, or k = M.

[0223] Optionally, when the first information indication field indicates that the second format does not include information of the service beam, the kth resource index indication field in the M resource index indication fields indicates a resource index corresponding to one of the at least one new beam, and / or the kth beam quality indication field in the M beam quality indication fields indicates a signal quality of one of the new beams. For example, k = 1, or k = M.

[0224] It should be noted that the signal quality of the M new beams indicated in the above format can be represented in a differential manner. For example, the reporting format includes the signal quality of the new beam with the best signal quality among the M new beams and the differential quality of the new beams other than the new beam with the best signal quality among the M new beams. The differential quality of the new beams other than the new beam with the best signal quality among the M new beams refers to the difference between the signal quality of the new beams other than the new beam with the best signal quality among the M new beams and the signal quality of the new beam with the best signal quality among the M new beams.

[0225] It should be noted that the second format described above can also include other fields, which are not limited in the present application.

[0226] III. When the reporting mode adopted by the terminal device is mode two, the terminal device reports the measurement result associated with the first event to the network device in a third format.

[0227] The third format includes at least one of the following: M resource index indication fields or M beam quality indication fields. M is an integer greater than or equal to 1. The M resource index indication fields are used to indicate the resource indexes corresponding to the M beams. That is, the M resource index indication fields correspond one-to-one to the M beams, and each resource index indication field is used to indicate the resource index corresponding to the beam corresponding to the resource index indication field. The M resource index indication fields correspond one-to-one to the M beam quality indication fields. The M beam quality indication fields are used to indicate the signal quality of the M beams, that is, the M beam quality indication fields correspond one-to-one to the M beams, and each beam quality indication field is used to indicate the signal quality of the corresponding beam. The M beams include part or all of the new beams in the at least one new beam, and M is an integer greater than or equal to 1. For example, the third format is as shown in Table 3:

[0228] Table 3

[0229] Optionally, if the resource indexes indicated by the M resource index indication fields include the resource index corresponding to the serving beam, the M beams include the serving beam. Or, if the resource indexes indicated by the M resource index indication fields do not include the resource index corresponding to the serving beam, the M beams do not include the serving beam. That is, the network device can determine whether the M beam quality indication fields include the beam quality indication field corresponding to the serving beam through whether the M resource index indication fields include the resource index indication field corresponding to the serving beam. In this implementation manner, the terminal device and the network device know the value of the resource index corresponding to the serving beam. For example, the resource corresponding to the serving beam and the resource corresponding to at least one new beam are configured in a same resource set, and the local index of the resource corresponding to the serving beam in the resource set is the resource index corresponding to the serving beam. It can be stipulated that if the measurement result associated with the first event includes the resource index corresponding to the serving beam and the signal quality, the third format includes the resource index corresponding to the serving beam and the signal quality of the serving beam. The resource index corresponding to the serving beam is indicated by the Mth resource index indication field in the third format. The signal quality of the serving beam is indicated by the Mth beam quality indication field in the third format.

[0230] It should be noted that the signal qualities of the M new beams indicated in the above format can be represented in a differential manner. For example, the reporting format includes the signal quality of the new beam with the best signal quality among the M new beams and the differential quality of the new beam other than the new beam with the best signal quality among the M new beams. The differential quality of the new beam other than the new beam with the best signal quality among the M new beams refers to the difference between the signal quality of the new beam other than the new beam with the best signal quality among the M new beams and the signal quality of the new beam with the best signal quality.

[0231] In a possible implementation manner, for mode one and mode two, the terminal device reports the measurement result corresponding to the first event through a unified format. The following introduces several possible reporting formats.

[0232] In a first implementation, the terminal device reports, to the network device, a measurement result corresponding to the first event in a fourth format. The fourth format includes at least one of the following: a first information indication field, P resource index indication fields, P beam quality indication fields, or a serving beam quality indication field. The first information indication field is used to indicate whether the fourth format includes information of the serving beam. The P resource index indication fields are used to indicate resource indexes corresponding to the P beams. Each resource index indication field is used to indicate a resource index corresponding to the beam corresponding to the resource index indication field. The P beam quality indication fields are used to indicate signal qualities of the P beams. Each beam quality indication field is used to indicate a signal quality of the beam corresponding to the beam quality indication field. P is an integer greater than or equal to 1. The serving beam quality indication field is used to indicate a beam quality of the serving beam. For example, the fourth format is as shown in Table 4:

[0233] Table 4

[0234] The signal quality of the serving beam and the signal qualities of the P new beams indicated in the above format can be represented in a differential manner. For example, the reporting format includes the signal quality of the serving beam and differential qualities of the P new beams. The differential quality of the P new beams refers to differences between the signal qualities of the P new beams and the signal quality of the serving beam, respectively. For another example, the reporting format includes a differential quality of the serving beam, a signal quality of a new beam with the best signal quality among the P new beams, and differential qualities of new beams other than the new beam with the best signal quality among the P new beams. The differential quality of the new beams other than the new beam with the best signal quality among the P new beams refers to differences between the signal qualities of the new beams other than the new beam with the best signal quality among the P new beams and the signal quality of the new beam with the best signal quality, respectively. The differential quality of the serving beam refers to a difference between the signal quality of the serving beam and the signal quality of the new beam with the best signal quality, such as the differential quality of the serving beam = the signal quality of the new beam with the best signal quality - the signal quality of the serving beam. The differential quality of the serving beam can also refer to a difference between the signal quality of the serving beam and (the signal quality of the new beam with the best signal quality - a first threshold value), such as the differential quality of the serving beam = (the signal quality of the new beam with the best signal quality - the first threshold value) - the signal quality of the serving beam.

[0235] In particular, the signal quality indicated by the first beam quality indication field in the above format is an absolute value of the signal quality of the resource corresponding to the first resource index indication field. The signal quality indicated by the remaining P-1 beam quality indication fields is a difference between the signal quality of the resource indicated by the remaining P-1 resource index indication fields and the signal quality indicated by the first beam quality indication field. The serving beam quality indication field indicates a difference between the signal quality of the serving beam and the signal quality indicated by the first quality indication field, i.e., the signal quality indicated by the serving beam quality field minus the signal quality indicated by the first beam quality indication field. Alternatively, the signal quality indicated by the first beam quality indication field minus the signal quality indicated by the serving beam quality field.

[0236] It can be specified whether some fields in the above fourth format exist in relation to the reporting mode adopted by the terminal device.

[0237] In a possible implementation, when the reporting mode adopted by the terminal device is mode one, the fourth format does not include the first information indication field. And / or, when the reporting mode adopted by the terminal device is mode one, the fourth format includes the serving beam quality indication field. That is, the information of the serving beam is always included in the fourth format, and the signal quality of the serving beam is indicated by the beam quality indication field corresponding to the serving beam. In this implementation, the fourth format includes: P resource index indication fields, P beam quality indication fields, and the serving beam quality indication field. When the reporting mode adopted by the terminal device is mode two, the fourth format does not include the serving beam quality indication field. And / or, when the reporting mode adopted by the terminal device is mode two, the fourth format includes the first information indication field. The first information indication field is used to indicate whether the information of the serving beam is included in the fourth format. In this implementation, the fourth format includes: the first information indication field, P resource index indication fields, and P beam quality indication fields.

[0238] Optionally, when the reporting mode adopted by the terminal device is mode one or the above reporting format does not include the serving beam quality indication field, if the fourth format includes the information of the serving beam, the s-th beam quality indication field in Table 4 indicates or indicates the beam quality of the serving beam. s is an integer greater than or equal to 1 and less than or equal to P.

[0239] Optionally, when the reporting mode adopted by the terminal device is mode one or the above reporting format does not include the serving beam quality indication field, if the fourth format includes the information of the serving beam, the s-th resource index indication field is meaningless, and the network device and / or the terminal device can ignore the s-th resource index indication field.

[0240] Optionally, if the fourth format does not include the information of the serving beam, the s-th beam quality indication field indicates the signal quality of a new beam, and / or the s-th resource index indication field indicates or indicates the resource index corresponding to the new beam. s is an integer greater than or equal to 1 and less than or equal to P. For example, s = 1, or s = P.

[0241] Optionally, if the fourth format includes the information of the serving beam (for example, the first information indication field indicates that the fourth format includes the information of the serving beam), the signal quality of the serving beam is indicated by the serving beam quality indication field. In this case, it can be further specified that the t-th field in the P resource index indication fields is meaningless, and the network device and / or the terminal device can ignore the t-th resource index indication field. Alternatively, it can be further specified that the t-th field in the P beam quality indication fields is meaningless, and the network device and / or the terminal device can ignore the t-th beam quality indication field. t is an integer greater than or equal to 1 and less than or equal to P. For example, t = 1, or t = P.

[0242] In another possible implementation, when the terminal device adopts the reporting mode one, the first information indication field is meaningless, and the terminal device can ignore the field. When the terminal device adopts the reporting mode two, the first information indication field is used to indicate whether the fourth format includes the information of the serving beam.

[0243] Optionally, the fourth format can further include other fields, which are not limited in the present application.

[0244] Implementation mode two: the terminal device reports the measurement result corresponding to the first event to the network device through a fifth format. The fifth format includes at least one of the following: R resource index indication fields, R beam quality indication fields, or a serving beam quality indication field. The R resource index indication fields are used to indicate the resource indexes corresponding to R beams. The R resource index indication fields correspond to the R beam quality indication fields one by one, and each resource index indication field is used to indicate the resource index corresponding to the corresponding beam. The R beam quality indication fields are used to indicate the signal quality of the R beams. The R beam quality indication fields correspond to the R beams one by one, and each beam quality indication field is used to indicate the signal quality of the corresponding beam. The R beams include part or all of the new beams in the at least one new beam. The serving beam quality indication field is used to indicate the signal quality of the serving beam, and R is an integer greater than or equal to 1. For example, the fifth format is as shown in Table 5:

[0245] Table 5

[0246] The signal quality of the serving beam and the signal quality of the R new beams indicated in the above format can be expressed in a differential manner. For example, the reporting format includes the signal quality of the serving beam and the differential quality of the R new beams. The differential quality of the R new beams refers to the difference between the signal quality of the R new beams and the signal quality of the serving beam respectively. For another example, the reporting format includes the differential quality of the serving beam, the signal quality of the new beam with the best signal quality among the R new beams, and the differential quality of the new beams other than the new beam with the best signal quality among the R new beams. The differential quality of the new beams other than the new beam with the best signal quality among the R new beams refers to the difference between the signal quality of the new beams other than the new beam with the best signal quality among the R new beams and the signal quality of the new beam with the best signal quality respectively. The differential quality of the serving beam refers to the difference between the signal quality of the serving beam and the signal quality of the new beam with the best signal quality, such as differential quality of the serving beam = signal quality of the new beam with the best signal quality - signal quality of the serving beam. The differential quality of the serving beam can also refer to the difference between the signal quality of the serving beam and (signal quality of the new beam with the best signal quality - a first threshold value), such as differential quality of the serving beam = (signal quality of the new beam with the best signal quality - a first threshold value) - signal quality of the serving beam.

[0247] Optionally, if the resource index indicated by the R resource index indication fields includes the resource index corresponding to the serving beam, the R beams include the serving beam. Or, if the resource index indicated by the R resource index indication fields does not include the resource index corresponding to the serving beam, the R beams do not include the serving beam. In this implementation manner, the terminal device and the network device know the value of the resource index corresponding to the serving beam. For example, the resource corresponding to the serving beam and the resource corresponding to at least one new beam are configured in the same resource set, and the local index of the resource corresponding to the serving beam in the resource set is the resource index corresponding to the serving beam.

[0248] It can be specified whether some fields of the above fifth format exist in relation to the reporting mode adopted by the terminal device.

[0249] In a possible implementation manner, when the reporting mode adopted by the terminal device is mode one, the fifth format includes the serving beam quality indication field. That is, the information of the serving beam is always included in the fifth format, and the signal quality of the serving beam is indicated by the serving beam quality indication field. In this implementation manner, the fifth format includes the R resource index indication fields, the R beam quality indication fields and the serving beam quality indication field. When the reporting mode adopted by the terminal device is mode two, the fifth format does not include the serving beam quality indication field. In this implementation manner, the fifth format includes the R resource index indication fields and the R beam quality indication fields.

[0250] In another possible implementation, whether the serving beam quality indication field exists is determined according to the reporting mode and the type of the first event. That is, the network device determines whether the fifth format includes the serving beam quality indication field according to the reporting mode adopted by the terminal device and the type of the first event. Specifically, when the type of the first event is event one, the serving beam quality indication field exists. Or, when the type of the first event is event two, if the reporting mode adopted by the terminal device is mode one, the serving beam quality indication field exists. Or, when the type of the first event is event two, if the reporting mode adopted by the terminal device is mode two, the serving beam quality indication field does not exist. In other words, if the type of the first event is event one, or the type of the first event is event two and the reporting mode adopted by the terminal device is mode one, the serving beam quality indication field exists. If the type of the first event is event two and the reporting mode adopted by the terminal device is mode two, the serving beam quality indication field does not exist.

[0251] Optionally, the length and / or meaning of the serving beam quality indication field is related to the type of the first event. That is, the network device can determine the length and / or meaning of the serving beam quality indication field according to the type of the first event.

[0252] In a possible implementation, if the type of the first event is event one, the serving beam quality indication field is used to indicate the signal quality of the serving beam, such as the RSRP of the serving beam. If the type of the first event is event two, the serving beam quality indication field is used to indicate the differential quality of the serving beam, such as the differential RSRP. The differential RSRP of the serving beam refers to the difference between the RSRP of the serving beam and the RSRP of the new beam with the largest RSRP. For example, the differential RSRP of the serving beam = the RSRP of the new beam with the largest RSRP - the RSRP of the serving beam.

[0253] In another possible implementation, the service beam quality indication field is used to indicate the differential RSRP of the serving beam regardless of the type of the first event. However, the value range of the service beam quality indication field is different for different event types. When the type of the first event is event one, the value range of the service beam quality indication field is a first range. When the type of the first event is event two, the value range of the service beam quality indication field is a second range. The first range is [-M, N], ( -M, N ), [-M, N ), or ( -M, N ], where M and N are positive integers. The second range is [0, K], (0, K), [0, K), or (0, K], where K is a positive integer. For example, the first range is [-14, 16] or [-16, 14]. The second range is [0, 30]. The quantization step corresponding to the first range and the second range can both be 2, and of course can also be other values, which are not limited here. For example, the first range is [-14, 16], the quantization step of the first range is 2, and the value of the service beam quality indication field can be -14, -12, -10, -8, -6, -4, -2, 0, 2, 4, 6, 8, 10, 12, 14, or 16. The same is true for the first range.

[0254] In another possible implementation, the service beam quality indication field is used to indicate the differential RSRP of the serving beam regardless of the type of the first event. However, the reference RSRP used to calculate the differential RSRP of the serving beam is different for different event types. When the type of the first event is event one, the reference RSRP used to calculate the differential RSRP of the serving beam is the first threshold in event one. That is, when the type of the first event is event one, the differential RSRP of the serving beam is equal to the first threshold in event one minus the RSRP of the serving beam. When the type of the first event is event two, the reference RSRP used to calculate the differential RSRP of the serving beam is the RSRP of the new beam with the largest RSRP among the R reported new beams. That is, when the type of the first event is event two, the differential RSRP of the serving beam is equal to the RSRP of the new beam with the largest RSRP among the R reported new beams minus the RSRP of the serving beam.

[0255] In another possible implementation, if the type of the first event is event one, the length of the service beam quality indication field is 7 bits. If the type of the first event is event two, the length of the service beam quality indication field is 4 bits. Of course, the service beam quality indication field can also be other bit lengths. For example, if the type of the first event is event one, the length of the service beam quality indication field is 10 bits. If the type of the first event is event two, the length of the service beam quality indication field is 5 bits.

[0256] In another possible implementation, whether the R resource index indication fields and / or the R beam quality indication fields exist is determined according to the type of the first event and / or the reporting mode. In other words, the network device determines whether the fifth format includes the R resource index indication fields and / or the R beam quality indication fields according to the type of the first event and / or the reporting mode.

[0257] In a possible implementation, if the type of the first event is event one, the R resource index indication fields and / or the R beam quality indication fields do not exist. If the type of the first event is event two, the R resource index indication fields and / or the R beam quality indication fields exist.

[0258] In another possible implementation, if the type of the first event is event one and the reporting mode is mode three, the R resource index indication fields and / or the R beam quality indication fields exist. If the type of the first event is event one and the reporting mode is mode four, the R resource index indication fields and / or the R beam quality indication fields do not exist. If the type of the first event is event two, the R resource index indication fields and / or the R beam quality indication fields exist. In other words, if the type of the first event is event two, or the type of the first event is event one and the reporting mode is mode three, the R resource index indication fields and / or the R beam quality indication fields exist. If the type of the first event is event one and the reporting mode is mode four, the R resource index indication fields and / or the R beam quality indication fields do not exist.

[0260] Mode four includes not reporting information of a new beam in the measurement result reporting. Alternatively, mode four includes that the measurement result corresponding to the reported first event does not include information of a new beam.

[0261] Optionally, the fifth format can further include other fields, which are not limited in the present application.

[0262] It should be noted that step 802 shows that the terminal device reports the measurement result corresponding to the first event. In actual application, the terminal device can also report the measurement result irrelevant to the first event. For example, the first measurement result includes the signal quality of the serving beam, the signal quality of the new beam 1, and the signal quality of the new beam 2. The signal quality of the new beam 2 is higher than the signal quality of the serving beam by a first threshold value. The signal quality of the new beam 1 is lower than the signal quality of the serving beam. The measurement result corresponding to the first event can include the signal quality of the serving beam and the signal quality of the new beam 2. The terminal device can further report the signal quality of the new beam 1.

[0266] I. The network device configures the terminal device with a first parameter or the terminal device is configured with the first parameter, and the first parameter is used to indicate one of mode one and mode two. For example, the network device sends second configuration information to the terminal device, and the second configuration information includes a first field, and the first field is used to indicate one of mode one and mode two. Correspondingly, the terminal device receives the second configuration information from the network device. That is, the first field is the first parameter.

[0267] II. If the network device configures the terminal device with a second parameter or the terminal device is configured with the second parameter, the terminal device adopts mode one; if the network device does not configure the terminal device with the second parameter or the terminal device is not configured with the second parameter, the terminal device adopts mode two. Alternatively, if the value of the second parameter is configured as a first value, the terminal device adopts mode one; if the value of the second parameter is configured as a second value, the terminal device adopts mode two. The first value can be a positive value such as ‘true’, ‘enabled’, or ‘on’. The second value can be a negative value such as ‘false’, ‘disabled’, or ‘off’.

[0268] III. If the network device configures the terminal device with the third parameter, or the terminal device is configured with the third parameter, the terminal device adopts mode two; if the network device does not configure the terminal device with the third parameter, or the terminal device is not configured with the third parameter, the terminal device adopts mode one. Alternatively, if the value of the third parameter is configured as a first value, the terminal device adopts mode one; if the value of the third parameter is configured as a second value, the terminal device adopts mode two. The first value can be a positive value such as 'true', 'enabled', or 'on'. The second value can be a negative value such as 'false', 'disabled', or 'off'.

[0269] Optionally, the embodiment shown in FIG. 8 further includes step 801b. Step 801b can be performed before step 801.

[0270] 801b. The network device sends the first configuration information to the terminal device. Correspondingly, the terminal device receives the first configuration information from the network device.

[0271] The first configuration information is used to configure the measurement configuration parameter. The measurement configuration parameter can include one or more reporting configurations. Each reporting configuration is associated with one or more resource configurations. One resource configuration can include a channel measurement resource for channel measurement. Alternatively, one resource configuration can include an interference measurement resource for interference measurement. Each resource configuration includes one or more resource sets. Among them, the resource set configured in the resource configuration for channel measurement is the resource set for channel measurement. The resource set configured in the resource configuration for interference measurement is the resource set for interference measurement. Each resource set includes one or more measurement resources.

[0272] It should be noted that if the embodiment shown in FIG. 8 further includes step 801a, there is no fixed execution order between step 801a and step 801b. 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. The specific application is not limited.

[0273] Optionally, the embodiment shown in FIG. 8 further includes step 801c. Step 801c can be performed before step 801.

[0274] 801c. The terminal device sends the capability information to the network device. Correspondingly, the network device receives the capability information from the terminal device.

[0275] Among them, the capability information includes at least one of the following: whether the terminal device supports triggered beam measurement result reporting, the number of beams supported by the terminal device for reporting, or information of the reporting mode supported by the terminal device.

[0276] Optionally, the information about the reporting mode supported by the terminal device includes at least one of the following: the reporting mode supported by the terminal device (for example, whether the terminal device supports mode one or mode two, or whether the terminal device supports mode one and mode two), information about whether the terminal device supports mode one, information about whether the terminal device supports mode two, the number of reporting modes supported by the terminal device, or whether the terminal device supports mode one and mode two at the same time.

[0277] Optionally, if the terminal device supports reporting of measurement results of triggered beams, it indicates that the terminal device supports mode one; or if the terminal device supports reporting of measurement results of triggered beams, it indicates that the terminal device supports mode two.

[0278] In the embodiment shown in FIG. 8, the terminal device measures a serving beam of the terminal device and at least one new beam to obtain first measurement results. The at least one new beam is a beam of the terminal device other than the serving beam. When a first event occurs, the terminal device reports measurement results corresponding to the first event to the network device according to a reporting mode adopted by the terminal device. The first event is that the signal quality of one or more new beams is higher than the signal quality of the serving beam by a first threshold value, the reporting mode adopted by the terminal device is mode one or mode two, and the measurement results associated with the first event belong to the first measurement results. Therefore, when the first event occurs, the terminal device reports the measurement results associated with the first event according to the reporting mode adopted by the terminal device. Thus, the terminal device reports measurement results based on event triggering. This is conducive to the terminal device reporting measurement results on demand, avoiding unnecessary reporting of measurement results, and reducing the uplink resource overhead. Further, the terminal device reports the measurement results corresponding to the first event to the network device according to the reporting mode adopted by the terminal device. Thus, the terminal device can report appropriate measurement results.
