Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a resource determination method, a resource update method, and related apparatus. Background Technology

[0002] Fifth-generation (5G) mobile communication systems can employ high-frequency communication, specifically ultra-high-frequency (UHF) signals (such as 28GHz) for data transmission. A major problem with high-frequency communication is the sharp decrease in signal energy with transmission distance, resulting in short transmission ranges. To overcome this issue, high-frequency communication uses analog beamforming technology. By weighting the antenna array, the signal energy is concentrated within a small angular range, forming a beam-like signal (called an analog beam, or simply a beam), thereby increasing the transmission distance. Both network devices and terminal devices utilize beamforming for transmission. Specific beamforming techniques are required for both uplink and downlink data transmission.

[0003] Network devices and terminal devices can select appropriate beams through a beam management process. Then, they communicate using the selected beams. The terminal device can also continue to measure the signal quality of multiple beams configured for it by the network device. The terminal device then periodically reports the signal quality of at least one beam with the best measured signal quality.

[0004] However, when terminal devices measure the signal quality of multiple beams, they do not distinguish between the types of beams, making it impossible for them to report the signal quality of different types of beams specifically. This prevents network devices from deciding whether to update the serving beam of the terminal devices. Summary of the Invention

[0005] This application provides a resource determination method, a resource update method, and related apparatus for a terminal device to determine a first serving beam measurement resource and / or at least one first beam measurement resource. The terminal device measures the first serving beam measurement resource and / or at least one first beam measurement resource, obtains measurement results, and reports the measurement results. This enables the terminal device to perform targeted measurements and report on specific types of measurement resources. This facilitates network devices in deciding whether to update the terminal device's serving beam based on the measurement results reported by the terminal device, thereby improving communication performance.

[0006] The first aspect of this application provides a resource determination method, which can be used on 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 with integrated circuits, or a chip, chip system, module, or control unit in the aforementioned device or apparatus; the specific implementation is not limited in this application. It should be noted that, in this application, when referring to a terminal device, it can refer to the terminal device itself, or to the chip, functional module, or integrated circuit in the terminal device that performs the method provided in this application; the specific implementation is not limited in this application. In the first aspect and its possible implementations, the method is described as being executed by a terminal device. The method includes: the terminal device determining a first serving beam measurement resource of the terminal device, and / or determining at least one first beam measurement resource corresponding to the first serving beam measurement resource, wherein the at least one first beam measurement resource is a measurement resource of the terminal device other than the first serving beam measurement resource; the terminal device measuring the first serving beam measurement resource and / or at least one first beam measurement resource to obtain a measurement result; and the terminal device sending the measurement result to a network device. This enables the terminal device to specifically measure and report specific types of measurement resources. This allows network devices to decide whether to update the service beam of terminal devices based on the measurement results reported by the terminal devices, thereby improving communication performance.

[0007] Based on the first aspect, in one possible implementation, the terminal device determines its first serving beam measurement resource, including: the terminal device using a first resource as the first serving beam measurement resource, where the first resource is a quasi-co-location (QCL) resource in the transmission configuration indicator (TCI) state indicated by the network device to the terminal device; or, the terminal device using a second resource as the first serving beam measurement resource, where the second resource is a synchronization signal and PBCH block (SSB) resource corresponding to the QCL resource in the TCI state indicated by the network device to the terminal device. This implementation defines two possible ways for the terminal device to determine the first serving beam measurement resource. Specifically, the terminal device can use either the first resource or the second resource to determine the first serving beam measurement resource, thereby achieving the determination of the first serving beam measurement resource and facilitating the terminal device's measurement of the first serving beam measurement resource.

[0008] Based on the first aspect, in one possible implementation, the terminal device determines its first serving beam measurement resource by: the terminal device using the serving beam measurement resource configured by the network device for the terminal device as the first serving beam measurement resource; or, the terminal device using either the first resource or the second resource as the first serving beam measurement resource, wherein the first resource is the QCL resource in the TCI state indicated by the network device for the terminal device; and the second resource is the SSB resource corresponding to the QCL resource in the TCI state indicated by the network device for the terminal device. This achieves the determination of the first serving beam measurement resource, facilitating the terminal device's measurement of the first serving beam measurement resource.

[0009] Based on the first aspect, in one possible implementation, the terminal device determines its first serving beam measurement resource by: if the network device has configured serving beam measurement resources for the terminal device, then the terminal device uses the configured serving beam measurement resources as the first serving beam measurement resource; if the network device has not configured serving beam measurement resources for the terminal device, then the terminal device uses either the first resource or the second resource as the first serving beam measurement resource. Alternatively, if the network device has configured serving beam measurement resources for the terminal device, then the terminal device uses the configured serving beam measurement resources as the first serving beam measurement resource; otherwise, the terminal device uses either the first resource or the second resource as the first serving beam measurement resource. This defines how the terminal device determines its first serving beam measurement resource. If there are configured serving beam measurement resources, the terminal device preferentially uses the configured serving beam measurement resources as the first serving beam measurement resource. If there are no configured serving beam measurement resources, the terminal device uses either the first resource or the second resource as the first serving beam measurement resource.

[0010] Based on the first aspect, in one possible implementation, the terminal device uses a first resource or a second resource as the first service beam measurement resource, including: the terminal device receiving first configuration information from a network device, the first configuration information being used to configure the terminal device to use the first resource or the second resource as the first service beam measurement resource; then, the terminal device using the first resource or the second resource as the first service beam measurement resource according to the first configuration information. In this implementation, the network device configures the terminal device to determine the first service beam measurement resource, thereby enabling the terminal device to use the first resource or the second resource as the first service beam measurement resource based on the first configuration information. This facilitates the terminal device in measuring the first service beam measurement resource.

[0011] Based on the first aspect, in one possible implementation, the terminal device uses either a first resource or a second resource as its first serving beam measurement resource. This includes: if the QCL resource of the TCI state indicated by the network device to the terminal device is a channel status information reference signal (CSI-RS) resource for beam management, then the terminal device uses the first resource as the first serving beam measurement resource; or, if the QCL resource of the TCI state indicated by the network device to the terminal device is a CSI-RS resource for time-frequency tracking, then the terminal device uses the second resource as the first serving beam measurement resource. In this implementation, the terminal device determines the first serving beam measurement resource based on the type of the QCL resource of the TCI state indicated to the terminal device. This ensures that the terminal device correctly determines the first serving beam measurement resource. Furthermore, the terminal device can determine the first serving beam measurement resource itself without needing to indicate the beam measurement resource, reducing signaling overhead.

[0012] Based on the first aspect, in one possible implementation, the terminal device uses a first resource or a second resource as its first serving beam measurement resource, including: if at least one first beam measurement resource is of type CSI-RS resource, then the terminal device uses the first resource as the first serving beam measurement resource; or, if at least one first beam measurement resource is of type SSB resource, then the terminal device uses the second resource as the first serving beam measurement resource. This enables the terminal device to determine the first serving beam measurement resource based on the type of at least one first beam measurement resource. This allows the terminal device to determine the first serving beam measurement resource independently, without requiring beam measurement resource indication, thus reducing signaling overhead.

[0013] Based on the first aspect, in one possible implementation, the method further includes: the terminal device sending first indication information to the network device, the first indication information being used to instruct the terminal device to use a first resource or a second resource as the first service beam measurement resource. In this implementation, after the terminal device determines the first service beam measurement resource itself, the terminal device reports the method used to determine the first service beam measurement resource to the network device. This enables the network device to determine the first service beam measurement resource.

[0014] Based on the first aspect, in one possible implementation, the method further includes: a terminal device receiving first configuration information from a network device, the first configuration information being used to configure the terminal device to use a first resource or a second resource as the first service beam measurement resource. In this implementation, the network device configures the terminal device to determine the first service beam measurement resource, thereby enabling the terminal device to use either the first resource or the second resource as the first service beam measurement resource based on the first configuration information. This facilitates the terminal device's measurement of the first service beam measurement resource. Based on the first aspect, in one possible implementation, the network device configures a first reporting configuration for the terminal device, the first reporting configuration being used to configure the terminal device to report measurement results; the first reporting configuration is associated with a resource set for channel measurement; if the resource set includes CSI-RS resources, the terminal device uses the first resource as the first service beam measurement resource; or, if the resource set includes SSB resources, the terminal device uses the second resource as the first service beam measurement resource. In this implementation, the terminal device determines the first service beam measurement resource according to the resource type in the resource set configured for the terminal device. This enables the terminal device to correctly determine the first service beam measurement resource. Furthermore, the terminal equipment can determine the first service beam measurement resource on its own, without the need for beam measurement resource instruction, thus reducing signaling overhead.

[0015] Based on the first aspect, in one possible implementation, the terminal device determines its first serving beam measurement resource by: the terminal device receiving second configuration information from a network device, the second configuration information being used to configure the first serving beam measurement resource. This enables the network device to explicitly configure the first serving beam measurement resource for the terminal device, facilitating the terminal device's measurement of the first serving beam measurement resource.

[0016] Based on the first aspect, in one possible implementation, the method further includes: the terminal device receiving second indication information from the network device, wherein the second indication information is used to update the first serving beam measurement resource, and the second indication information includes at least one of the following: a cell index, a resource index, a resource type identifier, a reporting configuration index, or an event index; the cell index is the index of the cell corresponding to the new serving beam measurement resource indicated by the resource index; the resource index is the index of the new serving beam measurement resource; the resource type identifier is used to indicate the type of the new serving beam measurement resource indicated by the resource index; the reporting configuration index is used to indicate the reporting configuration, and the reporting configuration index indicates that the second indication information updates the serving beam measurement resource corresponding to the reporting configuration indicated by the reporting configuration index; the event index is used to indicate the event, and the event index indicates that the second indication information updates the serving beam measurement resource corresponding to the event indicated by the event index. In this implementation, if the network device explicitly configures the serving beam measurement resource for the terminal device, the network device can also update the serving beam measurement resource for the terminal device. This is beneficial for improving the communication performance between the terminal device and the network device. Furthermore, the second indication information includes the fields shown above, thereby indicating the service beam measurement resources updated by the second indication information and the new service beam measurement resources indicated.

[0017] Based on the first aspect, in one possible implementation, the second indication information is carried in radio resource control (RRC) signaling, downlink control information (DCI), or medium access control element (MAC CE).

[0018] Based on the first aspect, in one possible implementation, the method further includes: the terminal device determining the type of the new service beam measurement resource indicated by the second indication information according to the second indication information.

[0019] Based on the first aspect, in one possible implementation, the terminal device determines the type of the new serving beam measurement resource indicated by the second indication information according to the second indication information. This includes: the terminal device determining the type of the new serving beam measurement resource indicated by the second indication information based on the resource type identifier; or, the terminal device determining the type of the new serving beam measurement resource indicated by the second indication information based on the type of serving beam measurement resource corresponding to the reported configuration indicated by the reported configuration index; or, the terminal device determining the type of the new serving beam measurement resource indicated by the second indication information based on the type of serving beam measurement resource corresponding to the event indicated by the event index. Therefore, multiple implementations for the terminal device to determine the type of the new serving beam measurement resource are provided. For example, the terminal device can directly determine the type of the new serving beam measurement resource by combining the resource type identifier. Alternatively, the terminal device can determine the type of the new serving beam measurement resource by combining the reported configuration index, in which case the resource type identifier in the second indication information can be defaulted, thereby reducing signaling indication overhead. As another example, the terminal device can determine the type of the new serving beam measurement resource by combining the event index, in which case the resource type identifier in the second indication information can be defaulted, thereby reducing signaling overhead.

[0020] Based on the first aspect, in one possible implementation, the terminal device determines the reporting configuration corresponding to the service beam measurement resource updated by the second indication information based on the resource type of the new service beam measurement resource indicated by the second indication information. This enables the terminal device to determine which reporting configuration corresponds to the service beam measurement resource that the network device updated for it.

[0021] Based on the first aspect, in one possible implementation, if the resource type is an SSB resource, then the service beam measurement resource updated by the second indication information corresponds to the second reporting configuration, and the service beam measurement resource corresponding to the second reporting configuration is an SSB resource; or, if the resource type is a CSI-RS resource, then the service beam measurement resource updated by the second indication information corresponds to the third reporting configuration, and the service beam measurement resource corresponding to the third reporting configuration is a CSI-RS resource. In this implementation, the terminal device determines the reporting configuration corresponding to the service beam measurement resource updated by the second indication information based on the resource type indicated by the second indication information. This enables the terminal device to determine which reporting configuration corresponds to the service beam measurement resource updated by the network device.

[0022] Based on the first aspect, in one possible implementation, the method further includes: the terminal device determining the event corresponding to the service beam measurement resource updated by the second indication information based on the resource type of the new service beam measurement resource indicated by the second indication information. This enables the terminal device to determine which event's service beam measurement resource the network device updated for it.

[0023] Based on the first aspect, in one possible implementation, if the resource type is an SSB resource, then the event corresponding to the service beam measurement resource updated by the second indication information is the first event, and the service beam measurement resource corresponding to the first event is an SSB resource; or, if the resource type is a CSI-RS resource, then the event corresponding to the service beam measurement resource updated by the second indication information is the second event, and the service beam measurement resource corresponding to the second event is a CSI-RS resource. In this implementation, the terminal device determines the event corresponding to the service beam measurement resource updated by the second indication information based on the resource type indicated by the second indication information. This enables the terminal device to determine which event's service beam measurement resource the network device updated for it.

[0024] Based on the first aspect, in one possible implementation, the terminal device determines at least one first beam measurement resource, including: the terminal device using a third resource as at least one first beam measurement resource, the third resource including QCL resources in the TCI state configured by the network device for the terminal device, or QCL resources in a TCI state other than the TCI state indicated by the network device for the terminal device in the TCI state configured by the network device for the terminal device; or, the terminal device using a fourth resource as at least one first beam measurement resource, the fourth resource including QCL resources in the TCI state activated by the network device for the terminal device, or QCL resources in a TCI state other than the TCI state indicated by the network device for the terminal device in the TCI state activated by the network device for the terminal device. Alternatively, the terminal device may use a fifth resource as at least one first beam measurement resource; the fifth resource includes the SSB resource corresponding to the QCL resource in the TCI state configured by the network device for the terminal device, or the SSB resource corresponding to the QCL resource in a TCI state other than the TCI state indicated by the network device for the terminal device; or, the terminal device may use a sixth resource as at least one first beam measurement resource; the sixth resource includes the SSB resource corresponding to the QCL resource in the TCI state activated by the network device for the terminal device, or the SSB resource corresponding to the QCL resource in a TCI state other than the TCI state indicated by the network device for the terminal device. This implementation limits two possible implementations for the terminal device to determine at least one first beam measurement resource. Specifically, the terminal device can use a specific resource to determine at least one first beam measurement resource, thereby achieving the determination of at least one first beam measurement resource and facilitating the measurement of at least one first beam measurement resource by the terminal device.

[0025] Based on the first aspect, in one possible implementation, the method further includes: the terminal device sending third indication information to the network device, the third indication information being used to instruct the terminal device to use a third resource or a fourth resource as at least one first beam measurement resource; or the third indication information being used to instruct the terminal device to use a target resource among multiple resources as at least one first beam measurement resource; wherein the multiple resources include a third resource and a fourth resource, and the target resource is either the third resource or the fourth resource; or the multiple resources include a third resource and a fifth resource, and the target resource is either the third resource or the fifth resource; or the multiple resources include a fourth resource and a sixth resource, and the target resource is either the fourth resource or the sixth resource; or the multiple resources include a third resource, a fourth resource, a fifth resource, and a sixth resource, and the target resource is one of the third resource, a fourth resource, a fifth resource, and a sixth resource. In this implementation, after the terminal device determines at least one first beam measurement resource, the terminal device can report the method of determining at least one first beam measurement resource to the network device. This enables the network device to determine at least one first beam measurement resource.

[0026] Based on the first aspect, in one possible implementation, the method further includes: the terminal device receiving third configuration information from the network device, the third configuration information being used to configure the terminal device to use a third resource or a fourth resource as at least one first beam measurement resource. In this implementation, the network device configures the terminal device to determine the at least one first beam measurement resource in a specific manner. This enables the terminal device to use a third resource or a fourth resource as at least one first beam measurement resource based on the third configuration information, facilitating the measurement of the at least one first beam measurement resource by the terminal device. Alternatively, the third configuration information is used to configure the terminal device to use a target resource from a plurality of resources as at least one first beam measurement resource; wherein the plurality of resources includes a third resource and a fourth resource, and the target resource is either the third resource or the fourth resource; or the plurality of resources includes a third resource and a fifth resource, and the target resource is either the third resource or the fifth resource; or the plurality of resources includes a fourth resource and a sixth resource, and the target resource is either the fourth resource or the sixth resource; or the plurality of resources includes a third resource, a fourth resource, a fifth resource, and a sixth resource, and the target resource is one of the third resource, the fourth resource, the fifth resource, and the sixth resource.

[0027] Based on the first aspect, in one possible implementation, the method further includes: the terminal device using a third or fourth resource as at least one first beam measurement resource according to an event configured by the network device for the terminal device, wherein the event is associated with a first reporting configuration configured by the network device for the terminal device, the first reporting configuration being used to configure the terminal device to report the measurement result; or, the event is associated with at least one first beam measurement resource. In this implementation, the terminal device determines at least one first beam measurement resource in conjunction with the configured event. This allows the terminal device to determine the at least one first beam measurement resource itself, eliminating the need for the network device to indicate the at least one first beam measurement resource to the terminal device, thus reducing signaling overhead. Alternatively, the terminal device uses a target resource from a plurality of resources as at least one first beam measurement resource based on the events configured for the terminal device by the network device; wherein the plurality of resources include a third resource and a fourth resource, and the target resource is either the third resource or the fourth resource; or the plurality of resources include a third resource and a fifth resource, and the target resource is either the third resource or the fifth resource; or the plurality of resources include a fourth resource and a sixth resource, and the target resource is either the fourth resource or the sixth resource; or the plurality of resources include a third resource, a fourth resource, a fifth resource, and a sixth resource, and the target resource is one of the third resource, the fourth resource, the fifth resource, and the sixth resource.

[0028] Based on the first aspect, in one possible implementation, the method further includes: the terminal device receiving fourth configuration information from the network device, the fourth configuration information being used to configure at least one first beam measurement resource. This enables the network device to explicitly configure at least one first beam measurement resource for the terminal device, facilitating the terminal device's measurement of the at least one first beam measurement resource.

[0029] Based on the first aspect, in one possible implementation, if the terminal device uses explicitly configured serving beam measurement resources, then the terminal device uses at least one explicitly configured first beam measurement resource; or, if the first serving beam measurement resource used by the terminal device is a first resource or a second resource, then the at least one first beam measurement resource used by the terminal device is a third resource, a fourth resource, a fifth resource, or a sixth resource; wherein, the first resource is the QCL resource in the TCI state indicated by the network device to the terminal device; the second resource is the SSB resource corresponding to the QCL resource in the TCI state indicated by the network device to the terminal device; the third resource includes the QCL resource in the TCI state configured by the network device to the terminal device, or the QCL resource in a TCI state other than the TCI state indicated by the network device to the terminal device. L resources; the fourth resource includes QCL resources in the TCI state activated by the network device for the terminal device, or QCL resources in TCI states other than the TCI state indicated by the network device for the terminal device; the fifth resource includes SSB resources corresponding to the QCL resources in the TCI state configured by the network device for the terminal device, or SSB resources corresponding to the QCL resources in the TCI states configured by the network device for the terminal device other than the TCI state indicated by the network device for the terminal device; the sixth resource includes SSB resources corresponding to the QCL resources in the TCI state activated by the network device for the terminal device, or SSB resources corresponding to the QCL resources in the TCI states activated by the network device for the terminal device other than the TCI state indicated by the network device for the terminal device. In this implementation, the communication protocol can specify that the configuration methods corresponding to the first serving beam measurement resource and at least one first beam measurement resource are the same, either both using explicit configuration or both using implicit determination. This establishes the association between the first serving beam measurement resource and at least one first beam measurement resource in terms of determination method. The first service beam measurement resource and at least one first beam measurement resource are determined in the same manner.

[0030] Based on the first aspect, in one possible implementation, the network device configures a first reporting configuration for the terminal device. This first reporting configuration configures the terminal device to report the measurement results. The first reporting configuration is associated with at least one event. The terminal device sends the measurement results to the network device, including sending the measurement results corresponding to the occurrence of at least one event. This enables the terminal device to report the corresponding measurement results to the network device when the relevant event occurs, thereby avoiding unnecessary measurement results and resource waste.

[0031] Based on the first aspect, in one possible implementation, at least one event includes one or more of the following: the signal quality of the first serving beam measurement resource is less than or equal to a first threshold; at least M of the first beam measurement resources have signal quality higher than the signal quality of the first serving beam measurement resource, and the difference between the signal quality of the at least M first beam measurement resources and the signal quality of the first serving beam measurement resource is greater than or equal to a second threshold, where M is an integer greater than or equal to 1; at least M of the first beam measurement resources have signal quality greater than or equal to a third threshold.

The signal quality of the measurement resource with the worst signal quality among the resources is such that the difference between the signal quality of at least M first-beam measurement resources and the signal quality of the measurement resource with the worst signal quality is greater than or equal to the eighth threshold value, where M is an integer greater than or equal to 1; or, at least M first-beam measurement resources have signal quality higher than the signal quality of the measurement resources configured by the network device for the terminal device, and the difference between the signal quality of at least M first-beam measurement resources and the signal quality of the measurement resources configured by the network device for the terminal device is greater than or equal to the ninth threshold value, where M is an integer greater than or equal to 1. In this implementation, some possible events are exemplified, thereby enabling the terminal device to report the corresponding measurement results when the event occurs, reducing the overhead of reporting measurement results.

The terminal device measures the first serving beam measurement resource and / or at least one first beam measurement resource, obtains measurement results, and reports the measurement results. This enables the terminal device to specifically measure and report specific types of measurement resources. This facilitates network devices in deciding whether to update the terminal device's serving beam based on the measurement results reported by the terminal device, thereby improving communication performance.

For example, 5th generation (5G) systems, new radio (NR) systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, universal mobile telecommunication systems (UMTS), mobile communication systems after 5G networks (e.g., 6G mobile communication systems), vehicle-to-everything (V2X) communication systems, device-to-device (D2D) communication systems, Internet of Things (IoT) communication systems, industrial internet communication systems, or satellite communication systems, etc. The wireless communication systems involved in this application also include, but are not limited to, narrowband Internet of Things (NB-IoT) systems.

[0146] The communication systems to which this application applies include terminal equipment and network equipment. Terminal equipment and network equipment are described below.

[0147] Terminal equipment, also known as UE, mobile station (MS), mobile terminal (MT), fixed wireless access (FWA), customer premise equipment (CPE), etc., refers to devices that include wireless communication capabilities (providing voice / data connectivity to users). Examples include handheld devices with wireless connectivity, in-vehicle devices, and machine-type communication (MTC) terminals. Currently, terminal devices can include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving (e.g., drones, vehicles), wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes. For example, wireless terminals in self-driving can be drones, helicopters, or airplanes. For example, wireless terminals in vehicle-to-everything (V2X) can be in-vehicle equipment, vehicle-mounted equipment, in-vehicle modules, vehicles, or ships. Wireless terminals in industrial control can be cameras, robots, or robotic arms. Wireless terminals in smart homes can be televisions, air conditioners, robot vacuums, speakers, or set-top boxes. The terminal device can also be a device or module that is connected to the communication system shown above and has corresponding communication functions. The terminal device usually contains a communication module, circuit or chip that performs the corresponding communication function, and the terminal device is also configured with program instructions for performing the corresponding communication function.

[0148] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus with integrated circuitry, or a chip, chip system, module, or control unit in the device or apparatus shown above; the specific application is not limited to any particular type. It should also be noted that in this application, when referring to a terminal device, it can refer to the terminal device itself, or to the chip, functional module, or integrated circuit within the terminal device that performs the method provided in this application; the specific application is not limited to any particular type.

[0149] A network device is a device deployed in a radio access network to provide wireless communication functions for terminal devices. Network devices may also be referred to as radio access network (RAN) entities, access nodes, network nodes, access network equipment, or communication devices, etc.

[0150] Specifically, the network equipment can be access network equipment for cellular systems related to the 3rd Generation Partnership Project (3GPP). For example, fourth-generation (4G) mobile communication systems, 5G mobile communication systems, or 6G mobile communication systems. The network equipment can also be access network equipment in open RAN (O-RAN or ORAN) or cloud radio access network (CRAN). Alternatively, the network equipment can also be access network equipment in a communication system formed by the integration of two or more of the above communication systems.

[0151] Network equipment includes, but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home-evolved Node B, or home Node B, HNB), baseband unit (BBU), access point (AP) in wireless fidelity (Wi-Fi) systems, macro base station, micro base station, wireless relay node, donor node, radio controller in CRAN scenarios, wireless backhaul node, transmission point (TP), or transmission and receiving point (TRP). Network equipment can also be access network equipment in 5G mobile communication systems. For example, a next-generation NodeB (gNB) in a new radio (NR) system, a transmission and reception point (TRP), a TP, or one or more antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system. Alternatively, network equipment can also be network nodes constituting a gNB or transmission point. Examples include a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). CUs and DUs can be separate entities or included in the same network element. For example, a BBU. RUs can be included in radio equipment or radio units. For example, in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Alternatively, network equipment can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, in V2X technology, network devices can be roadside units (RSUs).

[0152] It should be noted that CU (or CU-CP and CU-UP), DU, or RU may have different names in different systems, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called an open centralized unit (O-CU) or an open CU, DU can also be called an open distributed unit (O-DU), centralized unit control plane (CU-CP) can also be called an open centralized unit control plane (O-CU-CP) or an open CU-CP, centralized unit user plane (CU-UP) can also be called an open centralized unit user plane (O-CU-UP) or an open CU-UP, and RU can also be called an open radio unit (O-RU). This application does not impose any specific limitations. Any of the units CU, CU-CP, CU-UP, DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0153] Figure 1 This is a schematic diagram of an ORAN system according to an embodiment of this application. The ORAN system includes a core network, access network equipment, and UEs. Optionally, the ORAN system may further include... Figure 1 Other components besides those shown are not specifically limited in this application.

[0154] Access network devices can communicate with the core network (CN) via a backhaul link. Access network devices can also communicate with the UE via an air interface. Specifically, the BBU in the access network device communicates with the core network via a backhaul link. The RU in the access network device communicates with at least one UE via an air interface. The BBU communicates with at least one RU via a fronthaul link; the BBU and RU may or may not be co-located.

[0155] A BBU includes at least one CU and at least one DU, and the CU and DU can communicate with each other via at least one midhaul link.

[0156] One possible implementation is, such as Figure 2As shown, the CU is a logical node that carries the radio resource control (RRC), service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of access network equipment. The CU can connect to network nodes such as the core network through interfaces, such as the E2 interface. Optionally, the CU can have some core network functions. The CU (e.g., the PDCP layer and / or higher) connects to the DU (e.g., the radio link control (RLC) layer and lower layers of the DU) through interfaces, such as the F1 interface. Optionally, the F1 interface can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is the application protocol of the F1 interface, defining the signaling procedures of F1 in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0157] Optional, such as Figure 2As shown, the CU can be divided into CU-CP and CU-UP. CU-CP is a logical node carrying the control plane (PDCP-C) layer, which carries the RRC layer and the Packet Data Convergence Protocol layer, and is used to implement the CU's control plane functions. CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements in the core network can be access and mobility function (AMF) network elements, such as the access and mobility management function (AMF) in a 5G system. The AMF network element is responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover. CU-UP is a logical node carrying the user plane (PDCP-U) layer, which carries the SDAP layer and the Packet Data Convergence Protocol layer, and is used to implement the CU's user plane functions. CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements in the core network, such as the user plane function (UPF) in a 5G system, are responsible for data forwarding and receiving in terminal devices. The above CU and DU configurations are merely examples. In practical applications, the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or to have only some protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of the CU or DU can be divided according to service type or other system requirements. For example, based on latency, functions that require low latency can be placed in the DU, while functions that do not require low latency can be placed in the CU.

[0158] One possible implementation is, such as Figure 2 As shown, a DU is a logical node that carries the RLC layer, medium access control (MAC) layer, higher physical layer (Higher PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU connects to the RU through interfaces, which can be fronthaul interfaces. In some examples, the Higher PHY layer includes the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation.

[0159] One possible implementation is, such as Figure 2 As shown, the RU is a logical node that carries both lower physical layer (PHY) and radio frequency (RF) processing. In some examples, the RU can be a 3GPP transmission reception point (TRP), a remote radio head (RRH), or other similar entities. In some examples, the Low-PHY includes PHY processing functions such as Fast Fourier Transform (FFT), Inverse Fast Fourier Transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more UEs via a radio link.

[0160] The DU and RU can be co-located or not. The DU and RU exchange control plane and user plane information via a fronthaul link through the Lower-Layer Split CUS-Plane (LLS-CUS) interface. LLS-CUS may include a Lower-Layer Split control (LLS-C) interface and a Lower-Layer Splituser (LLS-U) interface, providing the 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 RU. The DU and RU exchange management information via a Lower-Layer Split management (LLS-M) interface on the fronthaul link; the management plane (M-Plane) refers to non-real-time management operations between the DU and RU.

[0161] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0162] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples.

[0163] It should be noted that network devices can be devices or apparatuses with chips, or devices or apparatuses with integrated circuits, or chips, chip systems, modules, or control units in the devices or apparatuses shown above; this application does not impose any specific limitations. It should also be noted that in this application, the term "network device" can refer to the network device itself, or to chips, functional modules, or integrated circuits within the network device that implement the methods provided in this application; this application does not impose any specific limitations.

[0164] To facilitate understanding of the technical solutions in the embodiments of this application, the following is combined with... Figure 3 and Figure 4 Two possible communication systems to which the method provided in the embodiments of this application is applicable are shown.

[0165] Figure 3 This is a schematic diagram of a communication system according to an embodiment of this application. Figure 3 As shown, the communication system includes at least one network device and at least one terminal device. For example, such as Figure 3 The network device 311, terminal device 321, and terminal device 322 are shown. Network device 311 can transmit data with terminal devices 321 and 322. The technical solutions of this application can be implemented between network device 311 and terminal devices 321 or 322.

[0166] Figure 4 This is another schematic diagram of the communication system according to an embodiment of this application. For example... Figure 4 As shown, the communication system may include at least two network devices and at least one terminal device. For example, as Figure 4 The network devices 411, 412, 413, and terminal device 421 are shown. Terminal device 421 can be provided with communication services by multiple network devices. For example, such as... Figure 4As shown, network device 411 can transmit data with terminal device 421, network device 412 can transmit data with terminal device 421, and network device 413 can transmit data with terminal device 421. That is, a terminal device can be provided with communication services simultaneously by multiple network devices. The technical solutions of this application can be implemented between terminal device 421 and network devices 411, 412, or 413.

[0167] To facilitate understanding of the technical solution of this application, some technical terms involved in this application will be introduced below.

[0168] 1. Beam: A beam is a communication resource. A beam can be wide, narrow, or other types of beams, and the technology used to form a beam can be beamforming technology or other techniques. Beamforming technology can specifically be digital beamforming technology, analog beamforming technology, and hybrid digital / analog beamforming technology. Different beams can be considered different resources.

[0169] In the NR protocol, a beam can be referred to as a spatial domain filter, spatial filter, spatial domain parameter, spatial parameter, spatial domain setting, spatial setting, quasi-colocation (QCL) information, QCL assumption, or QCL indication, etc. The beam can be indicated by the transmission configuration indicator state (TCI-state) parameter or by the spatial relation parameter. Therefore, in this application, the beam can be replaced by spatial domain filter, spatial filter, spatial parameter, spatial parameter, spatial setting, spatial setting, QCL information, QCL assumption, QCL indication, TCI-state (including uplink TCI-state and downlink TCI-state), or spatial relation, etc. These terms are also equivalent to each other. The beam can also be replaced with other beam-related terms, which are not limited herein.

[0170] The beam used to transmit signals can be called the transmission beam (Tx beam), spatial domain transmission filter, spatial transmission filter, spatial domain transmission parameter, spatial transmission parameter, spatial domain transmission setting, or spatial transmission setting. The downlink transmission beam can be indicated by TCI-state.

[0171] The beam used to receive signals can be called 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. The uplink transmit beam can be indicated by any of the following: spatial relation, uplink TCI-state, or a sounding reference signal (SRS) resource (indicating the transmit beam using that SRS). Therefore, the uplink beam can also be replaced by an SRS resource.

[0172] The transmitting beam can refer to the distribution of signal strength in different directions in space after a signal is transmitted through an antenna, while the receiving beam can refer to the distribution of signal strength in different directions in space of a wireless signal received from an antenna.

[0173] Furthermore, the beam can be a wide beam, a narrow beam, or other types of beam. The beamforming technology can be beamforming technology or other technologies. Specifically, beamforming technology can be digital beamforming technology, analog beamforming technology, hybrid digital beamforming technology, or hybrid analog beamforming technology, etc.

[0174] Beams are generally associated with resources. For example, during beam measurement, network devices measure different beams using different resources. The terminal devices provide feedback on the measured resource quality, allowing the network devices to determine the quality of the corresponding beam. During data transmission, beam information is also indicated through its corresponding resources. For instance, network devices use the TCI field in downlink control information (DCI) to indicate the physical downlink shared channel (PDSCH) beam information of the terminal devices.

[0175] In one possible implementation, multiple beams with the same or similar communication characteristics are considered as a single beam. A beam may include one or more antenna ports for transmitting data channels, control channels, and probe signals, etc. The one or more antenna ports forming a beam can also be considered as a set of antenna ports.

[0176] 2. Quasi-Co-location: Quasi-co-location indicates that multiple resources share one or more identical or similar communication characteristics. For multiple resources with quasi-co-location, identical or similar communication configurations can be used. For example, if two antenna ports have quasi-co-location, the large-scale channel characteristics of one port transmitting one symbol can be inferred from the large-scale channel characteristics of the other port transmitting one symbol. Large-scale characteristics can include: delay spread, average delay, Doppler spread, Doppler shift, average gain, receive parameters, terminal equipment receive beam number, transmit / receive channel correlation, receive angle of arrival, spatial correlation of receiver antennas, angel-of-arrival (AoA), average angle of arrival, AoA spread, etc. Specifically, this co-location indication is used to indicate whether at least two sets of antenna ports have a co-location relationship, including: the co-location indication indicating whether the channel state information reference signals transmitted by at least two sets of antenna ports originate from the same transmission point, or the co-location indication indicating whether the channel state information reference signals transmitted by at least two sets of antenna ports originate from the same beamgroup.

[0177] 3. TCI: Also known as TCI state. In both uplink and downlink transmission, correct beamforming is required for proper transmission between network devices and terminal devices. In downlink transmission, the network device needs to indicate its downlink transmit beam to the terminal device. The terminal device can then determine a suitable receive beam to receive information from the network device. In uplink transmission, the network device also needs to indicate to the terminal device which uplink transmit beam it uses to send information. The network device can determine the uplink transmit beam with better signal quality for the terminal device. Both uplink and downlink transmit beams can be indicated by their respective TCI states. Specifically, the downlink transmit beam can be indicated by the downlink TCI state, and the uplink transmit beam by the uplink TCI state.

[0178] In the 3GPP protocol, network devices can indicate the TCI status to terminal devices through the TCI field in the downlink control information (DCI). The TCI field is 3 bits in size and can be represented by 8 different codepoints. Each codepoint value of the TCI field can be associated with an index of a TCI status. This index uniquely identifies a TCI status, which can be either a downlink TCI status or an uplink TCI status. Each codepoint value of the TCI field can also be associated with two TCI status indices, which uniquely identify two TCI statuses, including one downlink TCI status and one uplink TCI status.

[0179] The downlink TCI status includes several parameters that terminal devices can use to determine information related to the downlink transmit beam, thereby determining the appropriate receive beam to receive information from the network device. The TCI status is configured by the network device for each terminal device, and the structure of the downlink TCI status is shown below:

[0180]

[0181]

[0182] Each TCI state includes its own index (tci-StateId) and two quasi-colocation information (QCL-info) entries. Each QCL-info entry includes a reference signal resource, indicating that the downlink transmission for that TCI state should use the same downlink timing, frequency offset, or receive beam as that reference signal resource. This is determined by the type of the QCL-info entry. The QCL type can have four values: {typeA, typeB, typeC, typeD}. When the QCL type is typeA, typeB, or typeC, the downlink transmission should use the same downlink timing and frequency offset as that reference signal resource. When the QCL type is typeD, the downlink transmission should use the same receive beam as that reference signal resource. Of the two QCL-info entries mentioned above, one is typeD, and the other is typeA, typeB, or typeC. The terminal device can determine which receive beam to use to receive the corresponding downlink transmission by using the typeD QCL-info entry. The specific execution steps are as follows:

[0183] Network devices indicate a specific downlink TCI state to terminal devices via DCI. The terminal device identifies a reference signal resource in the QCL information for this downlink TCI state (type D). The terminal device then uses the receive beam of this reference signal resource as the receive beam for downlink transmission. It should be noted that the receive beam of this reference signal resource is obtained by the terminal device in advance through a beam management process. Through this beam management process, the terminal device can determine which receive beam is optimal for receiving the reference signal resource and select that beam as the receive beam for that reference signal resource.

[0184] The uplink TCI state includes a reference signal resource, which indicates that uplink transmissions using this TCI state should employ the same uplink transmit beam as the reference signal resource. The terminal device can determine which transmit beam to use for uplink transmission by using this reference signal resource. In the uplink TCI state, the reference signal resource is not included in the QCL-info and does not distinguish between QCL types, because it does not need to reference uplink timing and frequency offset information; only the uplink transmit beam needs to be referenced. The structure of the uplink TCI state is as follows:

[0185]

[0186] The specific execution steps are as follows:

[0187] Network devices indicate a specific uplink TCI state to terminal devices via DCI. The terminal device then determines the reference signal resource within that uplink TCI state. The terminal device uses the transmission beam of this reference signal resource as its uplink transmission beam. It should be noted that the transmission beam of this reference signal resource is obtained by the terminal device in advance through a beam management process.

[0188] The following describes the configuration, activation, and indication of TCI status.

[0189] TCI-state configuration: Network devices configure multiple TCI-states to terminal devices via RRC signaling. Each of these TCI-states includes a QCL-Info of type type D. Network devices can also configure TCI-states that do not include a QCL-Info of type type D; however, these TCI-states are not used for data transmission beam indication and will not be discussed further here.

[0190] TCI-state activation: After configuring multiple TCI-states on a network device, eight of them need to be activated via MAC CE. These eight TCI-states correspond one-to-one with the eight values ​​of the TCI field in the DCI. That is, which eight TCI-states correspond to the eight values ​​of the TCI field in the DCI is determined by MAC CE.

[0191] TCI Status Indication: Network devices indicate a specific TCI-state through the TCI field in the DCI. For example, if the TCI field value in the DCI sent by the network device to the terminal device is 000, it indicates that the data transmission beam uses the TCI state corresponding to 000. The reference signal contained in the type D QCL-Info within this TCI state is the channel state information-reference signal (CSI-RS) with index #1, indicating that the beam used for data transmission is the same as the receiving beam corresponding to CSI-RS with index #1. The receiving beam corresponding to CSI-RS with index #1 can be determined through beam measurement procedures and is known to the terminal device. Therefore, by using the specific value of the TCI field, the terminal device can determine the beam corresponding to the data transmission beam and thus use the appropriate beam to send or receive data.

[0192] It should be noted that the three descriptions of TCI state, TCI-state, and TCI state in this article can be used interchangeably.

[0193] In this application, the QCL resources in the TCI state can be understood as the reference signal resources in the QCL information of type D in the TCI state, or the QCL resources of type D in the TCI state.

[0194] Currently, terminal devices and network devices select appropriate beams through a beam management process and communicate using those beams. The beam management process includes: first, coarse beam alignment based on the SSB (Solar Signal Block), and then fine beam adjustment based on the CSI-RS (Cyber-Independent Signaling System). The beam management process can be divided into three stages, which are described below.

[0195] Phase 1: Coarse beam alignment between network devices and terminal devices.

[0196] The base station performs beam scanning. Specifically, for example... Figure 5a As shown, the base station transmits SSBs to the terminal device at different times using beams from different directions. Simultaneously, the terminal device scans and receives beams, meaning it also receives SSBs from the network device at different times using beams from different directions. The terminal device determines the optimal beam for base station signal transmission and the optimal beam for terminal device signal reception based on the received signal strength. The beam used for base station signal transmission is simply called the base station beam, and the beam used for terminal device signal reception is simply called the terminal beam.

[0197] Specifically, the base station beam includes Terminal beams include like Figure 5b As shown, the base station sends SSB resource configuration information and reports resource configuration information to the terminal device. The base station beams include beams B0 to B15, i.e., M=5. The terminal beams include beams U0 to U3, i.e., N=4. The base station uses beam B0 to send SSBs to the terminal device through the corresponding SSB resources, uses beam B1 to send SSBs to the terminal device, and so on, using beam B5 to send SSBs to the terminal device. The terminal device measures the SSBs sent by the base station through beams B0 to B5 respectively through beams U0 to U3, and obtains the measurement results. The terminal device can determine the base station beam with better or better signal quality based on the measurement results. The terminal device feeds back the base station beam with better or better signal quality to the network device. It should be noted that in Phase 1, both the base station beams and the terminal beams can be understood as wide beams.

[0198] Phase Two: Base Station Beam Fine-Tuning.

[0199] The base station determines multiple first candidate beams based on the base station beam with the best or best signal quality identified in Phase 1. Each first candidate beam is a narrow beam. Specifically, for example... Figure 6aAs shown, the plurality of first candidate beams includes beams S0 to S2. For example, in the first stage described above, beam B3 is determined. This beam B3 is a wide beam, and the base station determines beams S0 to S2 based on beam B3. The terminal device determines the preferred terminal beam as beam U1 through the first stage described above. Figure 6b As shown, the base station sends CSI-RS configuration information to the terminal device. The network device uses beam S0 to send CSI-RS to the terminal device through the corresponding CSI-RS resources, uses beam S1 to send CSI-RS to the terminal device through the corresponding CSI-RS resources, and uses beam S2 to send CSI-RS to the terminal device through the corresponding CSI-RS resources. The terminal device receives the CSI-RS sent by the base station through different beams via beam U1 and obtains the measurement results. The terminal device can determine the candidate beam with better or best signal quality based on the measurement results. The terminal device then feeds back the first candidate beam with better or best signal quality to the network device. For example, as... Figure 7 As shown, the first candidate beam with better or better signal quality is beam S1. The base station uses this first candidate beam with better or better signal quality as the beam for communication with the terminal equipment.

[0200] Phase 3: UE beam fine-tuning.

[0201] The base station uses beam S1 to send CSI-RS to the terminal device, and the terminal device determines the superior terminal beam as beam U1 through Phase 1. Beam U1 is a wide beam. The terminal device determines multiple second candidate beams based on beam U1, such as... Figure 7 As shown, multiple second candidate beams include beams P1 to P4. The terminal device receives the CSI-RS transmitted by the base station through beam S1 via beams P1 to P4 to obtain the measurement results. The terminal device can select one beam from beams P1 to P4 based on the measurement results and use that beam as the beam for communication with network devices.

[0202] Network devices can be configured to allow terminal devices to report measurement results using one of three methods: periodic reporting, semi-persistent reporting, and aperiodic reporting. Semi-persistent reporting is also known as semi-static reporting.

[0203] Periodic Reporting: The network device sends reference signal resource configuration information to the terminal device. This reference signal resource configuration information includes periodic reference signal resources. The network device configures the terminal device with periodic measurement reference signals. The terminal device can periodically measure the reference signals based on this reference signal resource configuration information and periodically report the measurement results. Optionally, the measurement results obtained from the terminal device's periodic measurement reference signals can be carried on physical uplink control channel (PUCCH) resources.

[0204] Semi-persistent reporting: The terminal device periodically measures the reference signal, but reports the measurement results using a semi-persistent reporting method. In one possible implementation, the network device sends reference signal resource configuration information to the terminal device. This information includes periodic reference signal resources. The network device configures the terminal device's periodic measurement reference signal. When the terminal device receives an activation signaling message (e.g., MAC CE, or DCI) from the network device, it can continuously report the measurement results. Alternatively, the network device can send a deactivation command to the terminal device to deactivate its semi-persistent reporting process. 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 an activation signaling message from the network device, it continuously measures the reference signal and reports the measurement results. When the terminal device receives a deactivation command from the network device, it stops reporting the measurement results. Furthermore, the measurement results can be carried on PUCCH resources or Physical Uplink Shared Channel (PUSCH) resources.

[0205] Aperiodic reporting: When the terminal device receives a trigger command from the network device, it measures a reference signal and reports the measurement result. After completing the reporting, the terminal device stops reporting the measurement result. Optionally, the reference signal can be a periodic reference signal, a semi-persistent reference signal, or an aperiodic reference signal. Optionally, the measurement result is carried on the PUSCH resource.

[0206] Therefore, measurement results are either reported periodically or triggered by network devices sending instruction signals to the terminal devices for semi-continuous or non-periodic reporting. This means the timing of reporting is entirely determined by the network devices. Release 19 introduces UE- or event-triggered reporting of measurement results, thus avoiding unnecessary reporting and resource waste.

[0207] Network devices and terminal devices can select suitable beams through the aforementioned beam management process. Then, the network device and terminal device communicate using the selected beams. The terminal device can also continue to measure the signal quality of multiple beams configured for it by the network device. The terminal device then periodically reports the signal quality of at least one beam with the best measured signal quality. However, when measuring the signal quality of multiple beams, the terminal device does not distinguish between the types of beams, resulting in the inability to specifically report the signal quality of different types of beams. This prevents the network device from deciding whether to update the terminal device's serving beam. This application provides a corresponding technical solution to enable the terminal device to specifically measure and report specific types of measurement resources. This facilitates the network device's decision on whether to update the terminal device's serving beam based on the measurement results reported by the terminal device, improving communication performance. For details, please refer to the relevant descriptions in the embodiments below.

[0208] In this application, the term "terminal device measuring the first serving beam measurement resource" can also be described as: the terminal device measuring the reference signal carried by the first serving beam measurement resource, or the terminal device measuring the reference signal corresponding to the serving beam carried by the first serving beam measurement resource. Similarly, the term "terminal device measuring at least one first beam measurement resource" can also be described as: the terminal device measuring the reference signal carried by at least one first beam measurement resource, or the terminal device measuring the reference signal corresponding to at least one first beam carried by at least one first beam measurement resource.

[0209] In this application, an event refers to an event related to a UE-initiated report, an event related to a measurement result report initiated by the terminal device, an event related to a report (or measurement result) after the terminal device actively performs a measurement, or an event related to specific conditions for a measurement result report initiated by the terminal device. For example, the terminal device may actively perform measurements (such as beam measurements or channel measurements) to obtain measurement results related to the event. Another example is that the terminal device may perform measurements based on reference signals according to the configuration of reference signal resources to obtain measurement results related to the event. Yet another example is that the terminal device actively performs measurements and reports measurement results related to the event when specific conditions are met. The event may also be referred to as any of the following: a trigger event, a layer 1 (L1) trigger event, a channel state information (CSI) measurement reporting trigger event, a beam measurement reporting trigger event, an L1 CSI reporting trigger event, an L1 beam measurement reporting trigger event, etc. The naming of these events is not limited in this application.

[0210] In this application, the network device configures one or more reporting configurations for the terminal device. Each reporting configuration corresponds to one or more resource configurations. These one or more resource configurations include a set of resources for channel measurement. This resource set includes serving beam measurement resources. Therefore, the serving beam measurement resources can be referred to as the serving beam measurement resources corresponding to the reporting configuration.

[0211] In this application, the network device configures one or more events, or configures one or more events, for the terminal device. In one possible implementation, each event or type of event can be associated with a corresponding reporting configuration, which corresponds to one or more resource configurations. The one or more resource configurations include a serving beam measurement resource. Therefore, the serving beam measurement resource corresponding to the event can be the serving beam measurement resource corresponding to the reporting configuration for that event. In another possible implementation, each event or type of event can be associated with one or more corresponding resource configurations, which include a serving beam measurement resource. Therefore, the serving beam measurement resource corresponding to the event can be the serving beam measurement resource in the one or more resource configurations.

[0212] The technical solution of this application is described below with reference to specific embodiments.

[0213] Figure 8 This is a schematic diagram of one embodiment of the resource determination method according to this application. Please refer to... Figure 8 The methods include:

[0214] 801. The terminal device determines a first serving beam measurement resource of the terminal device, and / or determines at least one first beam measurement resource corresponding to the first serving beam measurement resource.

[0215] The at least one first beam measurement resource is a measurement resource of the terminal device other than the first serving beam measurement resource. For example, the at least one first beam measurement resource can be understood as a candidate beam measurement resource of the terminal device. For example, the at least one first beam measurement resource is a QCL resource in a TCI state other than the TCI state indicated to the terminal device in the TCI state configured by the network device for the terminal device. As another example, the at least one first beam measurement resource is a QCL resource in a TCI state other than the TCI state indicated to the terminal device in the TCI state activated by the network device for the terminal device.

[0216] The first serving beam measurement resource and at least one first beam measurement resource are configured by the network device for the terminal device for the same measurement reporting process. Therefore, the at least one first beam measurement resource is referred to as the at least one first beam measurement resource corresponding to the first serving beam measurement resource. The terminal device measures the first serving beam measurement resource and the at least one first beam measurement resource and reports the corresponding measurement results. The resource types corresponding to the first serving beam measurement resource and the at least one first beam measurement resource are the same. For example, the resource types corresponding to the first serving beam measurement resource and the at least one first beam measurement resource are both SSB resources or CSI-RS resources.

[0217] Optionally, the first service beam measurement resource of the terminal device includes one or more service beam measurement resources of the terminal device.

[0218] The following describes two implementation methods for the terminal equipment to determine the measurement resources of the first service beam. Other implementation methods are also applicable to this application, and this application does not limit them.

[0219] Implementation Method 1: The terminal device uses a first resource as the first serving beam measurement resource. Here, the first resource is the QCL resource in the TCI state indicated by the network device to the terminal device. The TCI state indicated by the network device to the terminal device can be translated as (indicated TCI-state). Optionally, the QCL resource in the TCI state indicated by the network device to the terminal device can be a CSI-RS resource used for beam management, or a CSI-RS resource used for time-frequency tracking. Optionally, the communication protocol or network device can specify that the first resource can only be a CSI-RS resource used for beam management.

[0220] Implementation Method 2: The terminal device uses the second resource as the first service beam measurement resource. The second resource is the SSB resource corresponding to the QCL resource in the TCI state indicated by the network device to the terminal device.

[0221] The SSB resource corresponding to the QCL resource in the TCI state indicated by the network device to the terminal device can be understood as an SSB resource that has a QCL relationship with that QCL resource. For example, this SSB resource is the source QCL resource in the QCL chain, and the source QCL resource is an SSB resource. This QCL chain is determined based on the QCL resources in the TCI state indicated by the network device to the terminal device. For example, the QCL resource in the TCI state indicated by the network device to the terminal device is a CSI-RS resource. The QCL resource in the TCI state corresponding to this CSI-RS resource is a tracking reference signal (TRS) resource. The TCI state corresponding to this CSI-RS resource can be understood as the TCI state used by the network device to send this CSI-RS resource, or the TCI state used by the network device to send the CSI-RS corresponding to this CSI-RS resource. And the QCL resource in the TCI state corresponding to this TRS resource is an SSB resource. The TCI state corresponding to the TRS resource can be understood as the TCI state used by the network device to send the TRS resource, or the TCI state used by the network device to send the TRS corresponding to the TRS resource. Therefore, the QCL resources (such as CSI-RS resources) in the TCI state indicated by the network device to the terminal device, the QCL resources (such as TRS resources) in the TCI state corresponding to the CSI-RS resource, and the QCL resources (such as SSB resources) in the TCI state corresponding to the TRS resource constitute a QCL chain. The source QCL resource of this QCL chain is the SSB resource, meaning the second resource is the SSB resource.

[0222] It should be noted that, optionally, the QCL resource in the TCI state indicated by the network device for the terminal device can be the QCL resource of Type D in that TCI state.

[0223] Implementation Method 3: The terminal device uses the service beam measurement resources configured by the network device for the terminal device as the first service beam measurement resource.

[0224] It should be noted that the specific implementation method adopted by the terminal device to determine the first service beam measurement resources can be determined by the terminal device itself and reported to the network device, or configured by the network device for the terminal device, or determined by the terminal device in combination with the resource configuration. This application does not limit the specific implementation method.

[0225] The following describes several possible implementation methods.

[0226] First, the terminal device independently determines the first serving beam measurement resource and instructs the network device to use either the first resource or the second resource as the first serving beam measurement resource. In other words, the terminal device informs the network device which resource it should select as the first serving beam measurement resource. Optionally, Figure 8 The illustrated embodiments also include Figure 9 Step 901 is shown.

[0227] 901. The terminal device sends a first instruction message to the network device. Correspondingly, the network device receives the first instruction message from the terminal device.

[0228] The first indication information is used to instruct the network device to use either the first resource or the second resource as the first serving beam measurement resource. In other words, the terminal device instructs the network device which resource to use as the first serving beam measurement resource.

[0229] It should be noted that step 901 and Figure 8 There is no fixed execution order between steps 801 to 803 in the illustrated embodiment. Step 901 can be executed first, followed by steps 801 to 803; or steps 801 to 803 can be executed first, followed by step 901; or, depending on the situation, steps 901 and steps 801 to 803 can be executed simultaneously. This application does not limit the specific execution order.

[0230] II. Network equipment configuration terminal equipment determines the method for measuring the first serving beam. Optionally, before step 801 above, Figure 8 The illustrated embodiments also include steps Figure 10 Step 1001 is shown.

[0231] 1001. 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.

[0232] The first configuration information is used to configure the terminal device to use either the first resource or the second resource as the first serving beam measurement resource. In other words, the network device configures the terminal device to use either the first resource or the second resource as the first serving beam measurement resource.

[0233] Optionally, the first configuration information is carried in RRC signaling.

[0234] Optionally, step 801 above may specifically include Figure 10 Step 1002 in the illustrated embodiment.

[0235] 1002. The terminal device uses either the first resource or the second resource as the first service beam measurement resource based on the first configuration information.

[0236] For example, if the first configuration information is used to configure the terminal device to use a first resource as the first service beam measurement resource, then the terminal device uses the first resource as the first service beam measurement resource. As another example, if the first configuration information is used to configure the terminal device to use a second resource as the first service beam measurement resource, then the terminal device uses the second resource as the first service beam measurement resource.

[0237] Third, the terminal equipment determines the first service beam measurement resource based on the resource configuration. Two possible implementation methods are shown below.

[0238] In one possible implementation, step 801 specifically includes: if the QCL resource for the TCI state indicated by the terminal device is a CSI-RS resource for beam management, then the terminal device uses the first resource as the first serving beam measurement resource; or, if the QCL resource for the TCI state indicated by the terminal device is a CSI-RS resource for time-frequency tracking, then the terminal device uses the second resource as the first serving beam measurement resource. The CSI-RS resource for beam management refers to a CSI-RS resource configured with a 'repetition' parameter. The CSI-RS resource for time-frequency tracking refers to a CSI-RS resource configured with a 'trs-Info' parameter.

[0239] In one possible implementation, step 801 specifically includes: if the QCL resource of the TCI state indicated by the network device to the terminal device is a periodic beam-managed CSI-RS resource, then the terminal device uses the first resource as the first serving beam measurement resource; if the QCL resource of the TCI state indicated by the network device to the terminal device is a semi-persistent CSI-RS resource or an aperiodic CSI-RS resource, then the terminal device uses the second resource as the first serving beam measurement resource. Alternatively, if the QCL resource of the TCI state indicated by the network device to the terminal device is a periodic or semi-persistent CSI-RS resource for beam management, then the terminal device uses the first resource as the first serving beam measurement resource; if the QCL resource of the TCI state indicated by the network device to the terminal device is an aperiodic CSI-RS resource, then the terminal device uses the second resource as the first serving beam measurement resource. The CSI-RS resource for beam management refers to a CSI-RS resource configured with the 'repetition' parameter. CSI-RS resources used for time-frequency tracking refer to CSI-RS resources configured with the 'trs-Info' parameter.

[0240] In another possible implementation, if the network device configures a first reporting configuration for the terminal device, this first reporting configuration is used to configure the terminal device to measure a first serving beam measurement resource and / or at least one first beam measurement resource, and to report the measurement results. The first reporting configuration is associated with a resource set for channel measurement. This resource set may include at least one first beam measurement resource. If the resource set includes CSI-RS resources, the terminal device uses the first resource as the first serving beam measurement resource; if the resource set includes SSB resources, the terminal device uses a second resource as the first serving beam measurement resource.

[0241] In another possible implementation, if the network device configures at least one first beam measurement resource for the terminal device, this at least one first beam measurement resource corresponds to the first serving beam measurement resource and is used for beam measurement reporting. That is, the terminal device measures both the at least one first beam measurement resource and the first serving beam measurement resource and reports the measurement results. If the at least one first beam measurement resource is a CSI-RS resource, the terminal device uses the first resource as the first serving beam measurement resource; if the at least one first beam measurement resource is an SSB resource, the terminal device uses the second resource as the first serving beam measurement resource.

[0242] According to the above scheme, if at least one first beam measurement resource is a CSI-RS resource, the terminal device uses the first resource as the first serving beam measurement resource. However, this first resource may be a CSI-RS resource used for time-frequency tracking and cannot be used for beam measurement. Therefore, it can be stipulated that at least one first beam measurement resource cannot be a CSI-RS resource, and the first resource cannot be a CSI-RS resource used for time-frequency tracking. In other words, if the QCL resource in the TCI-state indicated by the network device to the terminal device is a CSI-RS resource used for time-frequency tracking, the corresponding at least one first beam measurement resource must be an SSB resource.

[0243] According to the above scheme, if at least one first beam measurement resource is a CSI-RS resource, the terminal device uses the first resource as the first serving beam measurement resource. However, semi-persistent CSI-RS resources and aperiodic CSI-RS resources may not be used in the above measurement process. Therefore, it can be stipulated that at least one first beam measurement resource cannot be a CSI-RS resource, and the first resource cannot be either a semi-persistent CSI-RS resource or an aperiodic CSI-RS resource. In other words, if the QCL resource in the TCI-state indicated by the network device to the terminal device is a semi-persistent CSI-RS resource or an aperiodic CSI-RS resource, the corresponding at least one first beam measurement resource must be an SSB resource. Alternatively, only aperiodic CSI-RS resources may not be used in the above measurement process. Therefore, it can be stipulated that at least one first beam measurement resource cannot be a CSI-RS resource, and the first resource cannot be an aperiodic CSI-RS resource. In other words, if the QCL resource in the TCI-state indicated by the network device to the terminal device is an aperiodic CSI-RS resource, the corresponding at least one first beam measurement resource must be an SSB resource.

[0244] In other words, if the at least one first beam measurement resource is a CSI-RS resource, the terminal device uses the first resource as the first serving beam measurement resource. If the at least one first beam measurement resource is an SSB resource, the terminal device uses the second resource as the first serving beam measurement resource.

[0245] It should be noted that the above illustrates how the terminal device uses either the first resource or the second resource as the first service beam measurement resource. In practical applications, network devices can also directly configure the first service beam measurement resource for the terminal device. The following section will discuss this further. Figure 11 The illustrated embodiment describes this implementation. Before step 801 above, Figure 8 The illustrated embodiments also include Figure 11 Step 1101 is shown.

[0246] 1101. The network device sends the second configuration information to the terminal device. Correspondingly, the terminal device receives the second configuration information from the network device.

[0247] The second configuration information is used to configure the first serving beam measurement resources. Optionally, the second configuration information is carried in RRC signaling.

[0248] Optional, Figure 8 Step 801 in the illustrated embodiment specifically includes Figure 11 Step 1102 is shown.

[0249] 1102. The terminal equipment uses the measurement resources configured by the second configuration information as the first service beam measurement resources.

[0250] Optionally, the communication protocol stipulates that if the QCL resource in the TCI state indicated by the network device to the terminal device is a CSI-RS resource used for time-frequency tracking, the terminal device can only use the explicitly configured serving beam measurement resource as the first serving beam measurement resource, and cannot use the aforementioned first resource or the second resource as the first serving beam measurement resource. In other words, if the QCL resource in the TCI state indicated by the network device to the terminal device is a CSI-RS resource used for time-frequency tracking, the terminal device can only use the measurement resource configured by the second configuration information as the first serving beam measurement resource, and cannot use the first resource or the second resource as the first serving beam measurement resource.

[0251] Optionally, the terminal device can determine whether to use the aforementioned first resource or second resource as the first service beam measurement resource, or to use the explicitly configured service beam measurement resource, based on whether the network device has configured service beam measurement resources for the terminal device. In other words, if the network device has configured service beam measurement resources for the terminal device, the terminal device uses the service beam measurement resources configured by the network device as the first service beam measurement resource. If the network device has not configured service beam measurement resources for the terminal device, the terminal device uses either the aforementioned first resource or second resource as the first service beam measurement resource. In this case, the terminal device can further determine whether to use the first resource or the second resource using the aforementioned method.

[0252] Optionally, the terminal device can determine whether to use the first resource or the second resource as the first serving beam measurement resource, or to use the explicitly configured serving beam measurement resource, based on a configuration parameter. For example, this configuration parameter can be used to configure whether the terminal device implicitly determines the first serving beam measurement resource, i.e., the terminal device uses one of the first and second resources as the first serving beam measurement resource. Alternatively, this configuration parameter can be used to configure whether the terminal device uses an explicitly configured serving beam measurement resource. If the terminal device determines to use one of the first and second resources as the first serving beam measurement resource based on this configuration parameter, the terminal device can further determine whether to use the first resource or the second resource as the first serving beam measurement resource using the method described above.

[0253] The following describes several implementation methods for a terminal device to determine at least one first beam measurement resource. Other implementation methods are also applicable to this application, and this application does not limit the specific implementation.

[0254] Implementation Method 1: The terminal device uses a third resource as at least one first beam measurement resource. The third resource includes the QCL resource in the TCI state configured by the network device for the terminal device, or the QCL resource in a TCI state other than the TCI state indicated by the network device for the terminal device. The TCI state configured by the network device for the terminal device may include a TCI-state where the QCL resource is an SSB resource, and / or a TCI-state where the QCL resource is a CSI-RS resource for time-frequency tracking, and / or a TCI-state where the QCL resource is a CSI-RS resource for beam management. Optionally, the configured TCI state may specifically refer to the TCI-state where the QCL resource configured by the network device for the terminal device is a CSI-RS resource for beam management. The CSI-RS resource for beam management may refer to a CSI-RS resource configured with the 'repetition' parameter. The CSI-RS resource for time-frequency tracking refers to a CSI-RS resource configured with the 'trs-Info' parameter.

[0255] Implementation Method 2: The terminal device uses a fourth resource as at least one first beam measurement resource. The fourth resource includes the QCL resource in the TCI state activated by the network device for the terminal device, or the QCL resource in a TCI state activated by the network device for the terminal device other than the TCI state indicated by the network device for the terminal device. The TCI state activated by the network device for the terminal device may include a TCI-state where the QCL resource is an SSB resource, and / or a TCI-state where the QCL resource is a CSI-RS resource for time-frequency tracking, and / or a TCI-state where the QCL resource is a CSI-RS resource for beam management. Optionally, the activated TCI state may specifically refer to a TCI-state where the QCL resource activated by the network device for the terminal device is a CSI-RS resource for beam management. The CSI-RS resource for beam management may refer to a CSI-RS resource configured with the 'repetition' parameter. The CSI-RS resource for time-frequency tracking refers to a CSI-RS resource configured with the 'trs-Info' parameter.

[0256] Implementation Method 3: The terminal device uses a fifth resource as at least one first beam measurement resource. The fifth resource includes the SSB resource corresponding to the QCL resource in the TCI state configured by the network device for the terminal device, or the SSB resource corresponding to the QCL resource in the TCI state configured by the network device for the terminal device other than the TCI state indicated by the network device for the terminal device.

[0257] Implementation Method 4: The terminal device uses a sixth resource as at least one first beam measurement resource. The sixth resource includes the SSB resource corresponding to the QCL resource in the TCI state activated by the network device for the terminal device, or the SSB resource corresponding to the QCL resource in the TCI state activated by the network device for the terminal device other than the TCI state indicated by the network device for the terminal device.

[0258] For information on the SSB resources corresponding to the QCL resources in the TCI state, please refer to the aforementioned introduction; it will not be repeated here.

[0259] Optionally, the QCL resource in the TCI state configured by the network device for the terminal device can be the Type D QCL resource in the TCI state configured by the network device for the terminal device. The QCL resource in the TCI state activated by the network device for the terminal device can be the Type D QCL resource in the TCI state activated by the network device for the terminal device.

[0260] It should be noted that the specific implementation method used by the terminal device to determine at least one first beam measurement resource can be determined by the terminal device itself and reported to the network device, or configured by the network device for the terminal device, or determined by the terminal device in combination with the resource configuration. This application does not limit the specific implementation method.

[0261] The following describes several possible implementation methods.

[0262] First, the terminal device independently determines at least one first beam measurement resource, and instructs the network device which of a plurality of resources it will use as the first beam measurement resource. This plurality of resources includes at least two of the third to sixth resources. For example, the plurality of resources includes the third and fourth resources; or the plurality of resources includes the third and fifth resources; or the plurality of resources includes the third and sixth resources; or the plurality of resources includes the fifth and sixth resources; or the plurality of resources includes the third, fourth, fifth, and sixth resources. In other words, it informs the network device which resource the terminal device will select as at least one first beam measurement resource. Optionally, Figure 8 The illustrated embodiments also include Figure 12 Step 1201 is shown.

[0263] 1201. The terminal device sends a third instruction message to the network device. Correspondingly, the network device receives the third instruction message from the terminal device.

[0264] The third indication information is used to instruct the terminal device to use a target resource from a plurality of resources as at least one first beam measurement resource. The target resource is a specific resource among the plurality of resources. For example, the plurality of resources includes a third resource and a fourth resource, and the target resource is either the third or the fourth resource; or, the plurality of resources includes a third resource and a fifth resource, and the target resource is either the third or the fifth resource; or, the plurality of resources includes a third resource and a sixth resource, and the target resource is either the third or the sixth resource; or, the plurality of resources includes a fourth resource and a sixth resource, and the target resource is either the fourth or the sixth resource; or, the plurality of resources includes a third resource, a fourth resource, a fifth resource, and a sixth resource, and the target resource is one of the third, fourth, fifth, and sixth resources. In other words, the terminal device informs the network device which of the plurality of resources the terminal device will use as at least one first beam measurement resource. For example, if the plurality of resources includes a third resource and a fourth resource, the third indication information is used to instruct the terminal device to use the third resource from the plurality of resources as at least one first beam measurement resource. Or, the third indication information is used to instruct the terminal device to use the fourth resource from the plurality of resources as at least one first beam measurement resource. For example, the multiple resources include a third resource and a fifth resource, and the third indication information is used to instruct the terminal device to use the fifth resource among the multiple resources as at least one first beam measurement resource.

[0265] It should be noted that step 1201 and Figure 8 In the illustrated embodiment, there is no fixed execution order between steps 801 and 803. Step 1201 can be executed first, followed by steps 801 to 803; or steps 801 to 803 can be executed first, followed by step 1201; or, depending on the situation, steps 1201 and 803 can be executed simultaneously. Figure 8 The specific steps 801 to 803 in the illustrated embodiments are not limited in this application.

[0266] It should be noted that this is optional, if Figure 8 The illustrated embodiments also include Figure 9 As shown in step 901, there is no fixed execution order between step 1201 and step 901. Step 901 can be executed first, followed by step 1201; or step 1201 can be executed first, followed by step 901; or, depending on the situation, steps 901 and 1201 can be executed simultaneously. This application does not limit the specific execution order.

[0267] II. Network equipment configuration terminal equipment determines at least one first beam measurement resource in a specific manner. Optionally, prior to step 801 above, Figure 8 The illustrated embodiments also include Figure 13 Step 1301 in the illustrated embodiment.

[0268] 1301. The network device sends third configuration information to the terminal device. Correspondingly, the terminal device receives the third configuration information from the network device.

[0269] The third configuration information is used to configure the terminal device to use a target resource from a variety of resources as at least one first beam measurement resource. In other words, the network device configures which of the various resources the terminal device uses to determine at least one first beam measurement resource. Please refer to the preceding descriptions for information on these various resources and the target resource.

[0270] Optionally, the third configuration information is carried in RRC signaling.

[0271] It should be noted that the third configuration information in step 1301 above and the above... Figure 10 The first configuration information in step 1001 shown can be the same configuration information, such as a single configuration parameter. That is, the network device configures the terminal device to use the first serving beam measurement resource and at least one first beam measurement resource through the same configuration information. For example, when the configuration parameter in the configuration information is a first value, the terminal device uses the first resource as the first serving beam measurement resource and the third resource as the first beam measurement resource. When the configuration parameter in the configuration information is a second value, the terminal device uses the second resource as the first serving beam measurement resource and the fifth resource as at least one first beam measurement resource. As another example, when the configuration parameter in the configuration information is a first value, the terminal device uses the first resource as the first serving beam measurement resource and the fourth resource as at least one first beam measurement resource. When the configuration parameter in the configuration information is a second value, the terminal device uses the second resource as the first serving beam measurement resource and the sixth resource as at least one first beam measurement resource.

[0272] It should be noted that this is optional, if Figure 8 The illustrated embodiments also include Figure 10 As shown in step 1001, then the above step 1301 is the same as the aforementioned... Figure 10 There is no fixed execution order among the steps 1001 shown. Step 1301 can be executed first, followed by step 1001; or step 1001 can be executed first, followed by step 1301; or, depending on the situation, steps 1301 and 1001 can be executed simultaneously. This application does not limit the specific execution order.

[0273] It should be noted that this is optional, if Figure 8 The illustrated embodiments also include Figure 11 As shown in step 1101, then the above step 1301 is the same as the aforementioned Figure 11There is no fixed execution order among the steps 1101 shown. Step 1101 can be executed first, followed by step 1301; or step 1301 can be executed first, followed by step 1101; or, depending on the situation, steps 1101 and 1301 can be executed simultaneously. This application does not limit the specific execution order.

[0274] Optionally, step 801 above specifically includes Figure 13 Step 1302 in the illustrated embodiment.

[0275] 1302. The terminal device uses a target resource from a variety of resources as at least one first beam measurement resource based on the third configuration information.

[0276] For example, if the third configuration information is used to configure the terminal device to use a third resource as at least one first beam measurement resource, then the terminal device uses the third resource as at least one first beam measurement resource. As another example, if the third configuration information is used to configure the terminal device to use a fourth resource as at least one first beam measurement resource, then the terminal device uses the fourth resource as at least one first beam measurement resource. As yet another example, if the third configuration information is used to configure the terminal device to use a fifth resource as at least one first beam measurement resource, then the terminal device uses the fifth resource as at least one first beam measurement resource. As yet another example, if the third configuration information is used to configure the terminal device to use a sixth resource as at least one first beam measurement resource, then the terminal device uses the sixth resource as at least one first beam measurement resource.

[0277] Optionally, the terminal device can determine at least one first beam measurement resource based on the event configuration. In one possible implementation, step 801 specifically includes: the terminal device determining a target resource from a variety of resources as at least one first beam measurement resource based on the event configured for the terminal device by the network device.

[0278] Specifically, this event is associated with a first reporting configuration configured by the network device for the terminal device. This first reporting configuration configures the terminal device to measure a first serving beam measurement resource and / or at least one first beam measurement resource, and to report the measurement results. Alternatively, the event is associated with at least one first beam measurement resource. For example, if the event indicates that at least M (e.g., M=1) first beam measurement resources have signal quality higher than the first serving beam measurement resource, and the difference between the signal quality of the at least M first beam measurement resources and the signal quality of the first serving beam measurement resource is greater than a second threshold, then the terminal device uses a third or fifth resource as the at least one first beam measurement resource, where M is an integer greater than or equal to 1. As another example, if the event indicates that the first serving beam measurement resource does not belong to the K beam measurement resources with the best signal quality or does not belong to the beam measurement resources corresponding to the K TCI states activated by the network device for the terminal device, then the terminal device uses a fourth or sixth resource as the at least one first beam measurement resource, where K is an integer greater than or equal to 1.

[0279] Optionally, the terminal device determines the type of at least one first beam measurement resource based on the type of the first serving beam measurement resource. For example, if the first serving beam measurement resource is a first resource, then at least one first beam measurement resource is of type three. As another example, if the first serving beam measurement resource is a second resource, then at least one first beam measurement resource is of type five. As another example, if the first serving beam measurement resource is a first resource, then at least one first beam measurement resource is of type four. As another example, if the first serving beam measurement resource is a second resource, then at least one first beam measurement resource is of type six. As another example, if the first serving beam measurement resource is a first resource, then at least one first beam measurement resource is of type three or four. The specific type can be configured via RRC signaling. As another example, if the first serving beam measurement resource is a second resource, then at least one first beam measurement resource is of type five or six. The specific type can be configured via RRC signaling.

[0280] It should be noted that the above illustrates an implementation method where the terminal device uses a target resource from among multiple resources as at least one first beam measurement resource. In practical applications, network devices can also directly configure at least one first beam measurement resource for the terminal device. The following section will discuss this further. Figure 14 The illustrated embodiment describes this implementation. Before step 801 above, Figure 8 The illustrated embodiments also include Figure 14 Step 1401 is shown.

[0281] 1401. The network device sends the fourth configuration information to the terminal device. Correspondingly, the terminal device receives the fourth configuration information from the network device.

[0282] The fourth configuration information is used to configure at least one first beam measurement resource. Optionally, the fourth configuration information is carried in RRC signaling.

[0283] It should be noted that this is optional, if Figure 8 The illustrated embodiments also include Figure 10 As shown in step 1001, there is no fixed execution order between step 1401 and step 1001. Step 1001 can be executed first, followed by step 1401; or step 1401 can be executed first, followed by step 1001; or, depending on the situation, step 1001 and step 1401 can be executed simultaneously. This application does not limit the specific execution order.

[0284] It should be noted that this is optional, if Figure 8 The illustrated embodiments also include Figure 11 As shown in step 1101, there is no fixed execution order between step 1401 and step 1101. Step 1101 can be executed first, followed by step 1401; or step 1401 can be executed first, followed by step 1101; or, depending on the situation, step 1101 and step 1401 can be executed simultaneously. This application does not limit the specific execution order.

[0285] Optional, Figure 8 Step 801 in the illustrated embodiment specifically includes Figure 14 Step 1402 is shown.

[0286] 1402. The terminal device uses the measurement resources configured by the fourth configuration information as the at least one first beam measurement resource.

[0287] Optionally, the communication protocol specifies that if the terminal device uses explicitly configured serving beam measurement resources, then the terminal device uses at least one explicitly configured first beam measurement resource; or, if the first serving beam measurement resource used by the terminal device is an implicitly determined serving beam measurement resource, such as a first resource or a second resource, then the at least one first beam measurement resource used by the terminal device is also an implicitly determined at least one first beam measurement resource, such as a third resource, a fourth resource, a fifth resource, or a sixth resource. In other words, the communication protocol stipulates that both the first serving beam measurement resource and at least one first beam measurement resource must be implicitly determined or explicitly configured; one cannot be explicitly configured while the other is implicitly determined.

[0288] Furthermore, the network device can configure a resource set for the terminal device, which includes a first serving beam measurement resource and at least one first beam measurement resource. Optionally, the first measurement resource in the resource set is the first serving beam measurement resource, and all other measurement resources in the resource set, except for the first measurement resource, are the at least one first beam measurement resource. Alternatively, the last measurement resource in the resource set is the first serving beam measurement resource, and all other measurement resources in the resource set, except for the last measurement resource, are the at least one first beam measurement resource.

[0289] Optionally, the communication protocol specifies that the type of the first serving beam measurement resource and at least one first beam measurement resource must both be either CSI-RS resources or both SSB resources. One cannot be a CSI-RS resource and the other an SSB resource. If the first serving beam measurement resource is a CSI-RS resource, such as the first resource, then at least one first beam measurement resource can only be configured as a CSI-RS resource. If the first serving beam measurement resource is an SSB resource, such as the second resource, then at least one first beam measurement resource can only be configured as an SSB resource.

[0290] Optional, Figure 8 The illustrated embodiment also includes step 801a. Step 801a may be performed before step 801.

[0291] 801a. The terminal device sends capability information to the network device. Correspondingly, the network device receives the capability information from the terminal device.

[0292] The capability information includes at least one of the following: whether the terminal device supports measurement result reporting initiated by the terminal device, the number of events supported for measurement result reporting initiated by the terminal device, or the number of reporting configurations supported for measurement result reporting initiated by the terminal device. For information on event types, please refer to the relevant description in step 803 below. Optionally, the number of reporting configurations supported by the terminal device for measurement result reporting initiated by the terminal device includes: periodic reporting configurations supported by the terminal device for measurement result reporting initiated by the terminal device; or semi-persistent reporting configurations supported by the terminal device for measurement result reporting initiated by the terminal device; or non-periodic reporting configurations supported by the terminal device for measurement result reporting initiated by the terminal device.

[0293] It should be noted that, optionally, the above... Figure 9 The first indication information shown is carried in the capability information in step 801a.

[0294] Optional, Figure 8 The illustrated embodiment also includes step 801b. Step 801b may be performed before step 801.

[0295] 801b. The network device sends configuration information to the terminal device. Correspondingly, the terminal device receives the configuration information from the network device.

[0296] The reported configuration information is used to configure the first reported configuration. This first reported configuration is associated with one or more resource configurations. These one or more resource configurations may include resource configurations for channel measurement. Optionally, these one or more resource configurations may also include resource configurations for interference measurement. Each of these one or more resource configurations includes one or more resource sets. It should be noted that the resource sets configured in the resource configuration for channel measurement are specifically for channel measurement, while the resource sets configured in the resource configuration for interference measurement are specifically for interference measurement. Each resource set includes one or more measurement resources.

[0297] It should be noted that steps 801 to 803 in this embodiment can be considered as a measurement reporting process. The configuration parameters corresponding to this measurement reporting process include the first reporting configuration configured by the aforementioned reporting configuration information and one or more resource configurations associated with the first reporting configuration. Optionally, the first reporting configuration includes relevant parameters required for calculating and reporting measurement results. The one or more resource configurations include the beam measurement resources to be measured. The aforementioned first serving beam measurement resources and at least one first beam measurement resource can both belong to the one or more resource configurations. Optionally, the first reporting configuration is associated with at least one event. For details on the at least one event, please refer to the relevant description in step 803 below, which will not be repeated here.

[0298] Therefore, it is understandable that, for the measurement reporting process corresponding to the first reporting configuration, the network device can configure a resource set for channel measurement for the terminal device. This resource set can be a resourcesetting, a resourceset, or a subset of a resourceset. The terminal device measures the measurement resources in this resource set to determine the signal quality of each measurement resource in the resource set.

[0299] It should be noted that there is no fixed execution order between steps 801a and 801b. Step 801a can be executed first, followed by step 801b; or step 801b can be executed first, followed by step 801a; or, depending on the circumstances, steps 801a and 801b can be executed simultaneously. This application does not impose any specific restrictions on this.

[0300] Optionally, the above Figure 10 The first configuration information in step 1001 is carried in the reported configuration information in step 801b above.

[0301] 802. The terminal equipment measures the first serving beam measurement resource and / or at least one first beam measurement resource to obtain the measurement results.

[0302] Optionally, in step 801b above, the reported configuration includes relevant parameters required for calculating the measurement results. The terminal device calculates the relevant parameters required for the measurement results and measures the first serving beam measurement resource and / or at least one first beam measurement resource to obtain the measurement results.

[0303] Optionally, the measurement results may include the signal quality of the first serving beam measurement resource, and / or the signal quality of at least one first beam measurement resource. For example, signal quality may be reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), and / or signal-to-interference plus noise ratio (SINR). Further details regarding the measurement results can be found in the relevant description in step 803 below.

[0304] 803. The terminal device sends the measurement results to the network device.

[0305] Optionally, the network device terminal device configures a first reporting configuration. This first reporting configuration configures the terminal device to measure a first serving beam measurement resource and / or at least one first beam measurement resource, and reports the measurement results. The first reporting configuration is associated with at least one event. Step 803 specifically includes: the terminal device sending the measurement results corresponding to the event occurring in the at least one event to the network device. Optionally, the at least one event includes one or more of the following:

[0323] It should be noted that M and K mentioned above can be determined by the terminal device, reported by the terminal device to the network device, configured by the network device, or specified by the communication protocol. For example, M=1. This application does not limit the specifics.

[0324] The units corresponding to the first to ninth thresholds mentioned above can be dBm (decibels per milliwatt) or dB (decibels). The first to ninth thresholds can be configured by the network device or specified by the communication protocol.

[0325] It should be understood that the measurement result corresponding to the event is the measurement result associated with the event. This measurement result may 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 or event occurrence may also be referred to as UE triggering or UE-initiated, etc.

[0326] As an example, the measurement result may include at least one or more of the following: RSRP, SINR, precoding matrix indicator (PMI), rank indication (RI), channel quality indicator (CQI), beam availability, uplink transmit timing adjustment, downlink receive timing change exceeding a threshold, resource identifier or antenna panel logical identifier (e.g., capability value identifier) ​​used to obtain the measurement result, cause of the event (e.g., receive beam change, transmit beam change, transmit and receive beam change, others), and event information (e.g., event index, or whether at least one event occurred).

[0327] For example, the at least one event includes the existence of a difference between the signal quality of a first beam measurement resource and the signal quality of a first serving beam measurement resource that is greater than a second threshold. The measurement result associated with the event may include at least one of the following: the index of the serving beam corresponding to the first serving beam measurement resource, the index of the new beam corresponding to the first beam measurement resource, the signal quality of the new beam corresponding to the first beam measurement resource, or information about the event. The index of the serving beam and the index of the new beam can both be reference signal (e.g., CSI-RS, SSB, SRS) indexes, and the signal quality can be RSRP or SINR, etc. Optionally, the measurement result associated with the event may also include the event's identifier or index.

[0328] Optionally, the measurement results corresponding to the event include at least one of the following:

[0329] 1. The index of the service beam corresponding to the first service beam measurement resource can also be understood as the reference signal index of type D in the currently indicated TCI state; or, the reference signal index of type D in the uplink TCI state (UL TCI-state) applied to the current uplink transmission (e.g., PUSCH transmission, PUCCH transmission, SRS transmission, and / or, physical random access channel (PRACH) transmission); or, the reference signal index of type D in the downlink / joint TCI state (DLorjointTCI-state) applied to the current downlink transmission (e.g., physical downlink control channel (PDCCH) transmission, physical downlink shared channel (PDSCH) transmission, and / or, CSI-RS transmission).

[0330] 2. The signal quality of the service beam corresponding to the first service beam measurement resource. For example, the RSRQ, RSRP, or SINR of the service beam.

[0331] The serving beam may include one or more beams, and this application does not limit this. The number of serving beams can be determined based on the number of uplink TCI states or downlink / common TCI states indicated by the network device, such as uplink TCI states or downlink / common TCI states indicated by DCI signaling. Alternatively, the number of beams included in the serving beam may be predefined by the protocol or preconfigured by the network device. Or, the maximum number of beams included in the serving beam may be predefined by the protocol or configured by the network device.

[0332] 3. The index of at least one new beam can also be understood as the index of the reference signal whose QCL type is typeD in the activated TCI state (excluding the indicated TCI state), or it can be one or more reference signals (excluding the reference signal corresponding to the current serving beam) in the reference signals configured by the network device (such as the reference signal configured by the network device for measurement, or the reference signal configured by the network device for the terminal device to monitor the occurrence of events).

[0333] 4. Signal quality of at least one new beam. For example, RSRP or SINR of at least one new beam.

[0334] The at least one new beam may include one or more beams, and this application does not limit this. The number of beams included in the at least one new beam may be predefined by the protocol or preconfigured by the network device. Alternatively, the maximum number of beams included in the at least one new beam may be predefined by the protocol or configured by the network device.

[0335] 5. Cell information can also be understood as which cell the reported measurement result corresponds to, or the reference signal resources of which cell the reported measurement result is measuring. For example, cell information can be the handover candidate cell identifier, non-serving cell identifier, component carrier (CC) index, or physical cell identifier (PCI).

[0336] 6. Reasons why the service beam quality is below a threshold (e.g., the first threshold). For example, network equipment beam misalignment, terminal equipment receive beam misalignment, transmit / receive beam misalignment, etc. "Misalignment" can also be replaced with terms like "expired" or "invalid." Alternatively, it could indicate whether a CSI-RSset measurement with "repetition" set to "on" is triggered to poll the receive beam on the terminal equipment side.

[0337] 7. Reference signal resource set index, such as the CSI-RS resource set index, the CSI-IM resource set index, the channel state information synchronization signal and PBCH block (CSI-SSB) resource set index, or a reference signal resource set index configured by the network device for the terminal device to monitor the occurrence of events, used to indicate which reference signal resource set the currently serving beam and / or at least one new beam reported belongs to.

[0338] 8. The index of the first report configuration, for example, the CSI report configuration identifier (CSI-ReportConfigId), or the index of the event-triggered report configuration.

[0339] 9. Event information, such as an index of the event that occurred, or one or more bits indicating whether an event occurred. For example, event information may consist of M bits. An index used to indicate an event that has occurred. For example, event information includes X bits, each corresponding to one of X events. The x-th bit of the X bits indicates whether the event corresponding to that x-th bit has occurred, where x = 1, 2, ..., X. For instance, if the x-th bit has a value of "0", then the x-th bit indicates that the event corresponding to that x-th bit has occurred; or, if the x-th bit has a value of "1", then the x-th bit indicates that the event corresponding to that x-th bit has occurred.

[0340] 10. Channel state information, which may include one or more of PMI, RI, CQI, and layer indication (LI).

[0341] In this embodiment, the terminal device determines a first serving beam measurement resource and / or at least one first beam measurement resource. This at least one first beam measurement resource is a measurement resource of the terminal device other than the first serving beam measurement resource. Then, the terminal device measures the first serving beam measurement resource and / or at least one first beam measurement resource to obtain a measurement result. The terminal device sends the measurement result to the network device. Therefore, before measuring the beam measurement resources, the terminal device can first determine the type of the beam measurement resource, specifically the first serving beam measurement resource and / or the first beam measurement resource. This allows the terminal device to specifically measure and report specific types of measurement resources. This is beneficial for the network device to decide whether to update the terminal device's serving beam based on the measurement results reported by the terminal device, thereby improving communication performance.

[0342] Figure 15 This is a schematic diagram of one embodiment of the resource update method according to this application. Please refer to... Figure 15 The methods include:

[0343] 1501. The network device sends a second instruction message to the terminal device. Correspondingly, the terminal device receives the second instruction message from the network device.

[0344] The second indication information is used to update the first serving beam measurement resource of the terminal device. In this implementation, the network device configures the first serving beam measurement resource for the terminal device through explicit configuration. If the serving beam of the terminal device changes, the network device can update the first serving beam measurement resource for the terminal device through the second indication information. For example, after the terminal device moves, the network device can indicate a new serving beam measurement resource for the terminal device.

[0345] Optionally, the second indication information includes at least one of the following: cell index, resource index, resource type identifier, reporting configuration index, or event index. The functions of these fields included in the second indication information are described below.

[0346] The cell index is the index of the cell corresponding to the new serving beam measurement resource indicated by the resource index.

[0347] The resource index is the index for this new service beam measurement resource.

[0348] The resource type identifier indicates the type of the new serving beam measurement resource. For example, the resource type can be an SSB resource or a CSI-RS resource. For instance, a resource type identifier value of 1 indicates that the new serving beam measurement resource is an SSB resource; a resource type identifier value of 0 indicates that the new serving beam measurement resource is a CSI-RS resource. As another example, a resource type identifier value of 0 indicates that the new serving beam measurement resource is an SSB resource; a resource type identifier value of 1 indicates that the new serving beam measurement resource is a CSI-RS resource.

[0349] The reporting configuration index is used to indicate the reporting configuration. The reporting configuration index indicates that the second indication information updates the service beam measurement resource corresponding to the reporting configuration indicated by the reporting configuration index. In other words, the new service beam measurement resource indicated by the resource index is used to update the service beam measurement resource corresponding to the reporting configuration indicated by the reporting configuration index. For example, a network device configures multiple reporting configurations for a terminal device, and each reporting configuration has a corresponding service beam measurement resource. The reporting configuration index indicates the corresponding reporting configuration, thus indicating that the second indication information updates the service beam measurement resource corresponding to the reporting configuration indicated by the reporting configuration index. Please refer to the relevant introduction above regarding the service beam measurement resources corresponding to the reporting configuration.

[0350] An event index is used to indicate an event or event type. This event index indicates that the second indication information updates the service beam measurement resource corresponding to the event or event type indicated by the event index. In other words, the new service beam measurement resource indicated by the resource index is used to update the service beam measurement resource corresponding to that event or event type. For example, a network device configures multiple events or types of events for a terminal device. Each event or type of event has a corresponding service beam measurement resource. Therefore, the new service beam measurement resource indicated by the resource index is used to update the service beam measurement resource corresponding to that event or event type. As another example, a network device configures multiple events or types of events for a terminal device. Each event or type of event corresponds to one or more reporting configurations, and each reporting configuration has a corresponding service beam measurement resource. Therefore, the new service beam measurement resource indicated by the resource index is used to update the service beam measurement resource corresponding to the reporting configuration for that event or event type.

[0351] Optionally, the second indication information is carried in RRC signaling, DCI, or MAC CE.

[0352] Optional, Figure 15 The illustrated embodiment also includes step 1502. Step 1502 may be performed after step 1501.

[0353] 1502. The terminal equipment determines the type of the new service beam measurement resource indicated by the second indication information based on the second indication information.

[0354] The following describes several possible implementations of step 1502. Other implementations are still applicable to this application, and this application does not limit them in any specific way.

[0355] Implementation Method 1: The second indication information includes an identifier of the resource type. Step 1502 above specifically includes: the terminal device determining the type of the new service beam measurement resource indicated by the second indication information based on the identifier of the resource type.

[0356] Implementation Method 2: The second indication information includes the reported configuration index but not the resource type identifier; that is, the resource type identifier is defaulted. Step 1502 specifically includes: the terminal device determines the type of the new service beam measurement resource indicated by the second indication information based on the type of service beam measurement resource corresponding to the reported configuration indicated by the reported configuration index. For example, if the service beam measurement resource corresponding to the reported configuration indicated by the reported configuration index is an SSB resource, then the type of the new service beam measurement resource indicated by the second indication information is an SSB resource. If the service beam measurement resource corresponding to the reported configuration indicated by the reported configuration index is a CSI-RS resource, then the type of the new service beam measurement resource indicated by the second indication information is a CSI-RS resource.

[0357] Implementation Method 3: The second indication information includes an event index but not a resource type identifier; that is, the resource type identifier is defaulted. Step 1502 specifically includes: the terminal device determines the type of the new service beam measurement resource indicated by the second indication information based on the type of service beam measurement resource corresponding to the event indicated by the event index. For example, if the service beam measurement resource corresponding to the reporting configuration corresponding to the event index is an SSB resource, then the type of the new service beam measurement resource indicated by the second indication information is an SSB resource. If the service beam measurement resource corresponding to the reporting configuration corresponding to the event index is a CSI-RS resource, then the type of the new service beam measurement resource indicated by the second indication information is a CSI-RS resource. For another example, if the service beam measurement resource corresponding to the event index is an SSB resource, then the type of the new service beam measurement resource indicated by the second indication information is an SSB resource. If the service beam measurement resource corresponding to the event index is a CSI-RS resource, then the type of the new service beam measurement resource indicated by the second indication information is a CSI-RS resource.

[0358] Optional, Figure 15 The illustrated embodiment also includes step 1503. Step 1503 may be performed after step 1501.

[0359] 1503. The terminal device determines the reporting configuration corresponding to the service beam measurement resource updated by the second indication information based on the resource type of the new service beam measurement resource indicated by the second indication information.

[0360] In this implementation, the second indication information includes the resource type identifier but not the reported configuration index, meaning the reported configuration index is the default.

[0361] Optionally, if the resource type is an SSB resource, the service beam measurement resource updated in the second indication information corresponds to the second reporting configuration, and the service beam measurement resource corresponding to the second reporting configuration is an SSB resource. That is, the second indication information updates the service beam measurement resource corresponding to the reporting configuration where the service beam measurement resource is an SSB resource. If the resource type is a CSI-RS resource, the service beam measurement resource updated in the second indication information corresponds to the third reporting configuration, and the service beam measurement resource corresponding to the third reporting configuration is a CSI-RS resource. That is, the second indication information updates the service beam measurement resource corresponding to the reporting configuration where the service beam measurement resource is a CSI-RS resource.

[0362] It should be noted that there is no fixed execution order between steps 1502 and 1503. Step 1502 can be executed first, followed by step 1503; or step 1503 can be executed first, followed by step 1502; or, depending on the circumstances, steps 1502 and 1503 can be executed simultaneously. This application does not impose any specific restrictions on this.

[0363] Optional, Figure 15 The illustrated embodiment also includes step 1504. Step 1504 may be performed after step 1501.

[0364] 1504. The terminal device determines the event corresponding to the service beam measurement resource updated by the second instruction information based on the resource type of the new service beam measurement resource indicated by the second instruction information.

[0365] In this implementation, optionally, the second indication information includes the identifier of the resource type but not the event index, i.e., the event index is the default.

[0366] Optionally, if the resource type is an SSB resource, the event corresponding to the serving beam measurement resource updated by the second indication information is the first event, and the serving beam measurement resource corresponding to the first event is an SSB resource. That is, the second indication information updates the serving beam measurement resource corresponding to the event where the serving beam measurement resource is an SSB resource. If the resource type is a CSI-RS resource, the event corresponding to the serving beam measurement resource updated by the second indication information is the second event, and the serving beam measurement resource corresponding to the second event is a CSI-RS resource. That is, the second indication information updates the serving beam measurement resource corresponding to the event where the serving beam measurement resource is a CSI-RS resource. Please refer to the previous section for details regarding the serving beam measurement resources corresponding to the events.

[0367] It should be noted that this is optional, if Figure 15 The illustrated embodiment includes step 1502. There is no fixed execution order between step 1502 and step 1504. Step 1502 can be executed first, followed by step 1504; or step 1504 can be executed first, followed by step 1502; or, depending on the situation, steps 1502 and 1504 can be executed simultaneously. This application does not limit the specific execution order.

[0368] It should be noted that this is optional, if Figure 15 The illustrated embodiment includes step 1503. There is no fixed execution order between step 1503 and step 1504. Step 1503 can be executed first, followed by step 1504; or step 1504 can be executed first, followed by step 1503; or, depending on the situation, steps 1503 and 1504 can be executed simultaneously. This application does not limit the specific execution order.

[0369] It should be noted that this is optional, if Figure 15 The illustrated embodiment also includes steps 1502 and 1503, so there is no fixed execution order between steps 1502, 1503 and 1504.

[0370] Depend on Figure 15 As shown in the illustrated embodiment, the terminal device receives second indication information from the network device, thereby enabling the terminal device to determine the updated service beam measurement resources provided by the network device. This facilitates the terminal device in measuring the updated service beam measurement resources and reporting the corresponding measurement results. This allows the network device to select beams based on the measurement results, improving communication performance.

[0371] It should be noted that the above Figure 8 The illustrated embodiments and Figure 15 The illustrated embodiments can be implemented in combination. For example, Figure 15 The illustrated embodiments can be used in Figure 8 The execution will then take place in the illustrated embodiment.

The memory can store computer program code, and the transceiver includes a transmitter 1931, a receiver 1932, radio frequency circuitry (not shown), an antenna 1933, and input / output devices (not shown).

[0413] When data needs to be transmitted, the processor performs baseband processing on the data to be transmitted and outputs a baseband signal to the radio frequency (RF) circuit.

The processor converts the baseband signal back into data and processes that data. For ease of explanation, Figure 19 Only one memory, processor, and transceiver are shown in the illustration.
