Description

Reference signal measurement and reporting method, measurement report receiving method and device

[0001] This application claims priority to Chinese Patent Application No. 202510388359.9, filed on March 27, 2025, entitled “Reference Signal Measurement and Reporting Method, Measurement Report Receiving Method and Apparatus”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a reference signal measurement and reporting method, a measurement report receiving method, and an apparatus. Background Technology

[0003] In cellular communication systems, terminal devices communicate with network devices based on cells. As a terminal device moves, it moves from its serving cell to a candidate cell. The candidate cell has a stronger signal for the terminal device. The network device can instruct the terminal device to hand over from the serving cell to the candidate cell. After the terminal device hands over to the candidate cell, transmission occurs between the terminal device and the network device using the transmission parameters of that candidate cell. The network device can determine these transmission parameters based on the channel state information (CSI) of the candidate cell.

[0004] Therefore, the terminal device needs to obtain the channel state information of the candidate cells and report it to the network device. Thus, how the terminal device should obtain the channel state information of the candidate cells and report it to the network device is a question worth considering. Summary of the Invention

[0005] This application provides a reference signal measurement and reporting method, a measurement report receiving method, and an apparatus for enabling a terminal device to measure and report reference signals of one or more candidate cells. It also enables a network device to obtain channel state information of the one or more candidate cells. Furthermore, the measurement report corresponds to first channel state information processing unit (CSI) information, which includes CPU usage time and / or the number of CPUs. This allows the determination of the number of CPUs and CPU usage time required for the terminal device to obtain and / or report the measurement report.

[0006] The first aspect of this application provides a reference signal measurement and reporting method. This method can be used in a terminal-side communication device, for example, executed by a terminal device. The terminal device can be a device or apparatus with a chip, or a device or apparatus with integrated circuits, or a chip, chip system, module, or control unit in the aforementioned device or apparatus; the specific implementation is not limited here. 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 here. 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 measuring one or more reference signal resources associated with a first reporting configuration to obtain a measurement report, wherein the one or more reference signal resources include reference signal resources of one or more candidate cells of the terminal device; the terminal device sending the measurement report, wherein the measurement report corresponds to first CPU information, and the first CPU information includes CPU occupancy time and / or the number of CPUs.

[0007] In the above technical solution, the terminal device measures one or more reference signal resources associated with the first reporting configuration and obtains a measurement report. These one or more reference signal resources include reference signal resources of one or more candidate cells of the terminal device. Then, the terminal device sends the measurement report. This measurement report corresponds to first CPU information, which includes CPU usage time and / or the number of CPUs. This enables the terminal device to measure and report the reference signals of one or more candidate cells. It also enables the network device to obtain the channel state information of the one or more candidate cells. Furthermore, the measurement report corresponds to first CPU information, which includes CPU usage time and / or the number of CPUs. This specifies the number of CPUs and CPU usage time required for the terminal device to obtain and / or report the measurement report, which helps avoid CPU waste by the terminal device.

[0008] Based on the first aspect, in one possible implementation, before the terminal device measures the reference signal corresponding to one or more reference signal resources associated with the first reported configuration, the method further includes: the terminal device receiving a first signaling, the first signaling being used to instruct the terminal device to switch to a target cell, the target cell being one of the one or more candidate cells.

[0009] In this implementation, before measuring the reference signal, the terminal device receives a first signaling instruction. This instruction instructs the network device to handover to the target cell. The terminal device can then measure the reference signal to obtain a measurement report. For example, the measurement report includes the measurement results of the target cell, including its CSI. This allows the network device to determine the transmission parameters of the target cell based on the measurement results after the terminal device hands over, and to schedule the terminal device using these parameters. This improves the reliability and efficiency of data transmission.

[0010] Based on the first aspect, in one possible implementation, the starting time of CPU occupancy is the time when the first moment has elapsed for the first duration, and the first moment includes any of the following:

[0012] The moment of receiving the first signaling;

[0013] The timing of sending the feedback signaling corresponding to the first signaling;

[0014] The transmission time of the feedback signaling corresponding to the first signaling is the time when the second duration and / or the third duration are intersected, where the second duration is a preset duration and the third duration is the duration of the target cell handover interruption;

[0015] The moment when the target cell handover is completed; or,

This enables the network device to instruct the terminal device to hand over to the target cell. Then, the terminal device can measure the reference signal to obtain a measurement report. For example, the measurement report includes the measurement results of the target cell, which includes the CSI of the target cell. This facilitates the network device determining the transmission parameters of the target cell based on the measurement results of the target cell after the terminal device hands over to the target cell, and scheduling the terminal device through these transmission parameters. This improves the reliability and efficiency of data transmission.

[0052] This implementation limits some possible implementations for the fourth time step. This helps to reasonably define the end time of CPU usage and avoids wasting CPU time on terminal devices.

[0053] Based on the first aspect, in one possible implementation, the CPU time is the time between the third time interval after the fifth time interval and the fourth time interval after the sixth time interval.

[0054] Based on the first aspect, in one possible implementation, the number of CPUs includes any of the following:

[0055] The first report should specify the number of reference signal resources associated with the configuration.

[0056] The first report should specify the number of activated reference signal resources among the reference signal resources associated with the configuration.

[0057] The first report should include the number of active reference signal resources among the reference signal resources associated with the configuration.

[0058] The first report is the number of reference signal resources of the target cell associated with the configuration. The target cell is one of one or more candidate cells.

[0062] This implementation method limits the possible ways to determine the number of CPUs, thus reasonably specifying the number of CPUs and avoiding CPU waste in terminal devices.

[0063] Based on the first aspect, in one possible implementation, the method further includes: the terminal device receiving first configuration information, the first configuration information being used to instruct a first reporting configuration, the first reporting configuration being used to obtain CSI information of one or more candidate cells.

[0064] In this implementation, the terminal device can obtain a first reporting configuration so that it can report the measurement results of one or more candidate cells according to the first reporting configuration. For example, if the reporting quantities configured in the first reporting configuration include a channel quality indicator (CQI), a rank indicator (RI), and / or a precoding matrix indicator (PMI), then the measurement results reported by the terminal device will include CQI, RI, and / or PMI.

[0065] Based on the first aspect, in one possible implementation, the first configuration information is further used to indicate the reference signal resource configuration associated with the first reporting configuration. The reference signal resource configuration includes one or more reference signal resources, which are used for CSI acquisition of the candidate cell. This facilitates the terminal device in measuring the reference signal resources in the reference signal resource configuration to obtain the measurement results corresponding to the first reporting configuration. In other words, it enables channel measurement of the candidate cell.

[0066] Based on the first aspect, in one possible implementation, the first reporting configuration is associated with the reference signal resources of a candidate cell; or, the first reporting configuration is associated with the reference signal resources of a candidate cell, and the first reporting configuration is included in the configuration information of the candidate cell; or, the first reporting configuration is associated with the reference signal resources of multiple candidate cells, and the first configuration information includes the reference signal resources of multiple candidate cells and the identifier of the candidate cell corresponding to each reference signal resource.

[0071] In this implementation, the terminal device can also send capability information to the network device, thereby facilitating the network device to reasonably configure reference signal resources and report configurations for the terminal device. This enables the terminal device to measure and report reference signals for candidate cells.

[0072] Based on the first aspect, in one possible implementation, if the capability information includes that the terminal device supports candidate cell CSI acquisition, then the terminal device is assumed to support CSI acquisition method one.

[0073] If the capability information includes that the terminal device supports candidate cell CSI acquisition, then by default the terminal device supports CSI acquisition method two; or,

[0074] If the capability information includes CSI acquisition method 2 supported by the terminal device, then the terminal device supports both CSI acquisition method 1 and CSI acquisition method 2 by default.

[0075] This implementation method addresses several possible ways to interpret the capabilities possessed by a terminal device when the capability information contains different content. This helps reduce the signaling overhead for indicating capabilities by the terminal device.

This enables the network device to obtain the channel state information of the one or more candidate cells.

For example, the measurement report includes the measurement results of the target cell, including its CSI.

This allows the network device to obtain channel state information of the one or more candidate cells. Furthermore, the measurement report corresponds to first CPU information, which includes CPU usage time and / or the number of CPUs. This allows the determination of the number of CPUs and CPU usage time corresponding to the measurement report.

[0296] The communication systems to which this application applies include terminal equipment and network equipment. Terminal equipment and network equipment are described below.

[0297] Terminal equipment, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), fixed wireless access (FWA), customer premises 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.

[0298] 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; this application does not impose any specific limitation. It should also be noted that in this application, when referring to a terminal device, it can refer to the terminal device itself, or it can be replaced with a chip, functional module, or integrated circuit in the terminal device that performs the method provided in this application; this application does not impose any specific limitation.

[0299] 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.

[0300] 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 future 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 resulting from the integration of two or more of the above communication systems.

[0301] 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 (WIFI) 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 reception point (or transmit / receive point, TRP). Network equipment can also be access network equipment in 5G mobile communication systems. For example, a next-generation NodeB (gNB), TRP, TP in a new radio (NR) system, or one or a group of antenna panels (including multiple antenna panels) in a base station in a 5G mobile communication system. Alternatively, network equipment can also be network nodes that constitute a gNB or transmission point. For example, a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. CU and DU can be set up separately or included in the same network element. For example, a BBU. RU 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, etc. For example, in V2X technology, network equipment can be a roadside unit (RSU).

[0302] 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.

[0303] Figure 1 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 UE. Optionally, the ORAN system may also include other components besides those shown in Figure 1, which is not limited in this application.

[0304] 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.

[0305] A BBU consists of 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.

[0306] In one possible implementation, as shown in Figure 2, the CU is a logical node carrying the radio resource control (RRC), service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of the 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.

[0307] Optionally, as shown in Figure 2, the CU can be split 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 (AMF) function 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. In the core network, network elements used to implement user plane functions, such as the user plane function (UPF) in a 5G system, are responsible for forwarding and receiving data in terminal devices. The above configuration of CU and DU is merely an example; in practical applications, the functions of CU and DU can be configured as needed. For example, CU or DU can be configured to have more protocol layer functions, or to have only some protocol layer processing functions. For instance, 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 CU or DU can be divided according to service type or other system requirements, such as by latency, placing functions that need to meet low latency requirements in the DU and functions that do not need to meet such latency requirements in the CU.

[0308] In one possible implementation, as shown in Figure 2, the DU is a logical node carrying the RLC layer, medium access control (MAC) layer, higher physical layer (Higher PHY) layer, and other functions. In some examples, the 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.

[0309] In one possible implementation, as shown in Figure 2, the RU is a logical node carrying 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 wireless link.

[0310] 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 Split user (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.

[0311] 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.

[0312] 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.

[0313] 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, when referring to network devices, it can refer to the network device itself, or it can be replaced with the chips, functional modules, or integrated circuits in the network device that implement the methods provided in this application; this application does not impose any specific limitations.

[0314] To facilitate understanding of the technical solutions of the embodiments of this application, the following, in conjunction with Figures 3 and 4, illustrates two possible communication systems to which the methods provided in the embodiments of this application are applicable.

[0315] Figure 3 is a schematic diagram of a communication system according to an embodiment of this application. As shown in Figure 3, the communication system includes at least one network device and at least one terminal device. For example, network device 311, terminal device 321, and terminal device 322 are shown in Figure 3. Network device 311 can transmit data with terminal device 321 and terminal device 322. The technical solution of this application can be executed between network device 311 and terminal device 321 or terminal device 322.

[0316] Figure 4 is another schematic diagram of the communication system according to an embodiment of this application. As shown in Figure 4, the communication system may include at least two network devices and at least one terminal device. For example, network devices 411, 412, 413, and terminal device 421 are shown in Figure 4. Terminal device 421 may be provided with communication services by multiple network devices. For example, as shown in Figure 4, network device 411 may transmit with terminal device 421, and network device 412 may transmit with terminal device 421. That is, a terminal device may be provided with communication services by multiple network devices simultaneously. The technical solutions of this application can be implemented between terminal device 421 and network devices 411, 412, or 413.

[0317] The following describes some of the technical terms used in this application.

[0318] Beam: A beam is a communication resource. A beam can be wide, narrow, or other types. The technology used to form a beam can be beamforming or other techniques. Beamforming technology can specifically be digital beamforming, analog beamforming, and hybrid digital / analog beamforming. Different beams can be considered different resources.

[0319] 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.

[0320] The beam used to transmit signals can be referred to as a transmission beam (Tx beam), a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, a spatial transmission parameter, a spatial domain transmission setting, or a spatial transmission setting. The transmission beam can also be called a downlink beam. In this application, the transmission beam, downlink beam, channel state information reference signal (CSI-RS), TCI-State, downlink / joint TCI state, synchronization signal / physical broadcast channel block (SS / PBCH block), and tracking reference signal (TRS) can be interchanged. The DL / joint TCI state can also be called a DL-orjointTCI state; that is, the DL / joint TCI state and the DL-orjointTCI state are interchangeable. The SS / PBCH block can be simply referred to as the synchronization signal block (SSB). DL stands for downlink.

[0321] The beam used to receive signals can be referred to as a reception beam (Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, a spatial domain reception setting, or a spatial reception setting. The uplink transmit beam can be indicated by any of the following: spatial relationship, transmission configuration indicator state (TCI-state), or sounding reference signal (SRS) resource (indicating the transmit beam using that SRS). The receive beam can also be referred to as the uplink beam. In this application, the receive beam, uplink beam, uplink TCI state (UL TCI state), DL / joint TCI state, sounding reference signal (SRS), CSI-RS, SSB, and TRS can be interchanged.

[0322] The transmit beam refers to the distribution of signal strength in different directions in space after a signal is transmitted through an antenna. The receive beam refers to the distribution of signal strength in different directions in space of the wireless signal received from the antenna.

[0323] Beams are generally associated with resources. For example, during beam measurement, network devices measure different beams using different resources. The terminal device provides feedback on the measured resource quality, allowing the network device 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 (transmission configuration indication) field in downlink control information (DCI) to indicate beam information to the terminal device.

[0324] 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.

[0325] Resources: In communication protocols, reference signals are configured as resources. Network devices allocate various reference signals to terminals as resources. Resource configuration can include parameters related to the reference signal, such as its time-frequency resource location, number of ports, and time-domain type. The time-domain type can also be understood as the type of resource. For example, the time-domain type can be periodic, semi-persistent, or aperiodic. Semi-persistent can also be called semi-static.

[0326] Resources can be either uplink or downlink signal resources. Uplink signals include, but are not limited to, sounding reference signals (SRS) and demodulation reference signals (DMRS). Downlink signals include, but are not limited to, channel state information reference signals (CSI-RS), cell specific reference signals (CS-RS), user equipment specific reference signals (US-RS), demodulation reference signals (DMRS), and SSBs. CSI-RS also includes non-zero power CSI-RS (NZP CSI-RS) and zero power CSI-RS (ZP CSI-RS).

[0327] In this application, the terms reference signal, reference signal resource, measurement resource, and reference signal measurement resource can be used interchangeably.

[0328] The following sections introduce the reference signal resource index, reference signal resource identifier, and reference signal resource indicator.

[0329] In this application, ID can be an abbreviation of any of the following: identifier, indication, indicator, index, identity, and identification. These terms are interchangeable. Specifically, the network device configures one or more reference signal resources for the terminal device. These reference signal resources are used to carry reference signals. In this application, the terms "reference signal" and "reference signal resource" are interchangeable. During configuration, each reference signal resource corresponds to a reference signal resource index or a reference signal resource identifier (id) for distinguishing reference signal resources. Furthermore, the network device can configure one or more sets of reference signal resources for the terminal device. Each set of reference signal resources includes one or more reference signal resources, and each set corresponds to a reference signal resource set identifier. Within each set of reference signal resources, each reference signal resource corresponds to a reference signal resource indicator. A reference signal resource indicator of 0 indicates the first reference signal resource in the set, a reference signal resource indicator of 1 indicates the second reference signal resource, and so on. When a network device indicates a reference signal resource in the reference signal resource set, or when a terminal device reports the measurement result of a reference signal resource in the reference signal resource set, the corresponding reference signal resource can be indicated by the reference signal resource indicator.

[0330] For example, a network device configures one or more NZP CSI-RS resources for a terminal device. These NZP CSI-RS resources are used to carry NZP CSI-RS signals. The terms "NZP CSI-RS" and "NZP CSI-RS resource" are interchangeable. Each NZP CSI-RS resource corresponds to a non-zero power CSI-RS resource identifier (NZP-CSI-RS-ResourceId) used to distinguish each NZP CSI-RS resource. Furthermore, a network device can configure one or more NZP CSI-RS resource sets. Each NZP CSI-RS resource set includes one or more NZP CSI-RS resources, and each NZP CSI-RS resource set includes an NZP CSI-RS resource set identifier (NZP-CSI-RS-ResourceSetId). Within each NZP CSI-RS resource set, each NZP CSI-RS resource corresponds to a CSI-RS resource indicator (CRI). For example, a CRI of 0 indicates the first NZP CSI-RS resource in the NZP CSI-RS resource set, a CRI of 1 indicates the second NZP CSI-RS resource in the same set, and so on. When a network device instructs a network device to measure and report an NZP CSI-RS resource in a specific NZP CSI-RS resource set, or when a terminal device measures and reports an NZP CSI-RS resource in a specific NZP CSI-RS resource set, the CRI can be used to indicate the corresponding NZP CSI-RS resource. The NZP-CSI-RS-ResourceId can be understood as a global identifier among all configured NZP-CSI-RS-Resources, and the CRI can be understood as a local identifier among all NZP-CSI-RS-Resources in the NZP CSI-RS resource set.

[0331] For example, a network device configures one or more ZP CSI-RS resources for a terminal device. These ZP CSI-RS resources are used to carry ZP CSI-RS. The terms "ZP CSI-RS" and "ZP CSI-RS resource" are often used interchangeably. Each NP CSI-RS resource corresponds to a Zero Power CSI-RS Resource Identifier (ZP-CSI-RS-ResourceId) used to distinguish each ZP CSI-RS resource. Furthermore, a network device can configure one or more ZP CSI-RS resource sets. Each ZP CSI-RS resource set includes one or more ZP CSI-RS resources, and each ZP CSI-RS resource set includes a ZP CSI-RS Resource Set Id. Within each ZP CSI-RS resource set, each ZP CSI-RS resource corresponds to a CRI. For example, a CRI of 0 indicates the first ZP CSI-RS resource in the ZP CSI-RS resource set, a CRI of 1 indicates the second ZP CSI-RS resource in the same set, and so on. The ZP-CSI-RS-ResourceId can be understood as a global identifier among all configured ZP-CSI-RS-Resources, while the CRI can be understood as a local identifier among all ZP-CSI-RS-Resources within the ZP CSI-RS resource set.

[0332] For example, a network device may configure one or more Channel State Information Interference Measurement (CSI-IM) resources for a terminal device. These CSI-IM resources are used to carry the Channel State Information Interference Measurement Reference Signal (CSI-IM RS). The terms CSI-IM RS and CSI-IM resource are interchangeable. Each CSI-IM resource corresponds to a CSI-IM resource identifier (CSI-IM-ResourceId) used to distinguish each CSI-IM resource. Furthermore, the network device may configure one or more CSI-IM resource sets. Each CSI-IM resource set includes one or more CSI-IM resources, and each CSI-IM resource set includes a CSI-IM resource set identifier (CSI-IM-ResourceSetId). Within a CSI-IM resource set, each CSI-IM resource corresponds to a CRI. For example, a CRI of 0 indicates the first CSI-IM resource in the set, a CRI of 1 indicates the second CSI-IM resource, and so on. When a network device instructs a CSI-IM resource within a specific CSI-IM resource set, or when a terminal device measures and reports a CSI-IM resource within a specific CSI-IM resource set, the corresponding CSI-IM resource can be indicated using the CRI. The CSI-IM-ResourceId can be understood as a global identifier among all configured CSI-IM resources, while the CRI can be understood as a local identifier among all CSI-IM resources within a CSI-IM resource set.

[0333] For example, a network device configures one or more SSB resources for a terminal device. These SSB resources are used to carry SSBs. The terms "SSB" and "SSB resource" are interchangeable. Each SSB resource corresponds to an SSB resource index (SSB-Index) used to distinguish each SSB resource. Furthermore, a network device can configure one or more SSB resource sets. Each SSB resource set includes one or more SSB resources, and each SSB resource set includes an SSB resource set identifier (CSI-SSB-ResourceSetId). Within an SSB resource set, each SSB resource corresponds to an SSB resource indicator (SS / PBCH Block Resource indicator, SSBRI). For example, an SSBRI of 0 indicates the first SSB resource in the SSB resource set, an SSBRI of 1 indicates the second SSB resource, and so on. When a network device indicates the SSB resources of a certain SSB resource set, or when a terminal device measures and reports the SSB resources of a certain SSB resource set, the SSBRI can be used to indicate the corresponding SSB resource. SSB-Index can be understood as a global identifier among all configured SSB resources, while SSBRI can be understood as a local identifier among all SSB resources in the SSB resource set.

[0334] For example, a network device configures one or more SRS resources for a terminal device. These SRS resources are used to carry SRS (Service Support Routing). The terms "SRS" and "SRS resource" are interchangeable. Each SRS resource corresponds to an SRS resource index (SRS-ResourceId) used to distinguish each SRS resource. Furthermore, a network device can configure one or more SRS resource sets. Each SRS resource set includes one or more SRS resources, and each SRS resource set includes an SRS resource set identifier (SRS-ResourceSetId). Within an SRS resource set, each SRS resource corresponds to an SRS resource indicator (SRI). For example, an SRI of 0 indicates the first SRS resource in the set, an SRI of 1 indicates the second SRS resource, and so on. When a network device indicates an SRS resource within a specific SRS resource set, or when a terminal device reports an SRS resource within a specific SRS resource set, the SRI can be used to indicate the corresponding SRS resource. SRS-ResourceId can be understood as a global identifier among all configured SRS resources, while SRI can be understood as a local identifier among all SRS resources in the SRS resource set.

[0335] Serving cell: The serving cell can be the primary cell (Pcell), secondary cell (Scell), or primary secondary cell (PScell) of the terminal device. Cells using the primary component carrier (PCC) can be called Pcells, and cells using the secondary component carrier (SCC) can be called Scells.

[0336] Candidate cell: A candidate cell for the terminal device. For example, a candidate cell can be a neighboring cell of the terminal device's serving cell. The physical cell identifier (PCI) of the candidate cell is different from that of the terminal device's serving cell.

[0337] In this application, "time" can refer to a time-domain symbol, time slot, frame, subframe, second, or millisecond, etc., and is not specifically limited in this application. A time-domain unit can refer to a time-domain symbol, time slot, frame, subframe, second, or millisecond, etc., and is not specifically limited in this application. A time-domain symbol can also be called a symbol, or an orthogonal frequency division multiplexing (OFDM) symbol.

[0338] In scenarios where terminal devices move between multiple cells, network devices need to determine, based on the measurement results of reference signals from candidate cells (not only geographically but also logically) fed back by the terminal devices, whether the terminal devices should prepare for cell handover, whether to perform cell handover, or which candidate cell to hand over to. For example, when the network device decides that the terminal device should perform cell handover, the network device sends cell handover signaling to the terminal. Specifically, this involves the following steps:

[0339] Step 1: Network devices send reference signal resources and report configuration information.

[0340] The network device sends a report configuration (ReportConfig) for the serving cell. This report configuration is associated with the reference signal resources of one or more candidate cells. The report configuration also includes the content information to be reported, such as the number of candidate cells L for which the terminal reports measurement results, the number of reference signals M reported by each cell, and whether to report the measurement results of the current serving cell.

[0341] Step 2: The terminal device measures the reference signal and reports the measurement results.

[0342] The measurement results include measurements from L cells, with each cell containing measurements of M reference signals. Each reference signal measurement includes a reference signal resource index (e.g., SSBRI) and corresponding signal strength information (e.g., RSRP or differential RSRP). Currently, only SSB resources of candidate cells are supported for measurement, reporting the SSB's RSRP or differential RSRP (i.e., the difference from the reported maximum RSRP).

[0343] Step 3: The network device sends a cell handover signaling message. This message instructs the terminal to hand over to the target cell. Correspondingly, the terminal device receives the cell handover signaling message.

[0344] For example, as shown in Figure 5, the terminal device is located in the serving cell and receives a cell handover signaling message. This cell handover signaling message indicates that the device should hand over to candidate cell #2. The terminal device may then hand over to candidate cell #2.

[0345] The cell handover signaling is an L1 / L2 triggered mobility cell switch command media access control (LTM Cell Switch Command MAC CE) signaling. It should be noted that in this application, the cell handover signaling and the L1 / L2 triggered mobility cell switch command media access control element can be described interchangeably. As shown in Figure 6, the cell handover signaling includes the following information:

[0346] (1) C: Indicates whether the MAC-CE includes contention-free random access (CFRA) related fields (such as Random Access Preamble index, Synchronization Signal Block / Physical Broadcast Channel index, Physical Random Access Channel Mask index, Secondary Uplink / Normal Uplink (S / U), Repetition Number). A value of 1 for the C field indicates inclusion; a value of 0 indicates exclusion.

[0347] (2) Target Config ID: This indicates the candidate target configuration index for cell handover, corresponding to LTM candidate identifier-1 (ltm-CandidateId-1), indicating that the handover is to the target candidate cell corresponding to ltm-CandidateId-1. The Target Config ID field is indicated by 3 bits.

[0348] (3) TA command: Timing advance (TA) for the target candidate cell. A value of all 1s in this field indicates invalidity (i.e., no valid TA is indicated);

[0349] (4) TCI state ID: Indicates the TCI state of the target candidate cell (indicates one from the TCI-state list in ltm-candidate);

[0350] (5) UL TCI state ID: Indicates the UL TCI state of the target candidate cell (one is indicated from the UL TCI-state list in ltm-candidate). (5) above exists only in separate mode. When the terminal device uses joint mode, it transmits using the TCI state indicated by the TCI state ID in (4) above. When the terminal device uses separate mode, in the downlink direction, it transmits using the TCI state indicated by the TCI state ID in (4) above. In the uplink direction, it transmits using the UL TCI state indicated by the UL TCI state ID in (5) above.

[0351] (6) Random Access Preamble index: Indicates the preamble ID of CFRA, used to trigger CFRA.

[0352] (7) SSB / PBCH index: Indicates the SSB corresponding to CFRA.

[0353] (8) PRACH Mask index: Used to indicate an RO from the random access channel occasion (RACH occasion, RO) associated with the above SSB. When the repetition number is non-zero, the terminal ignores this field.

[0354] (9) Repetition number: The number of times the CFRA preamble is repeated (the field value k indicates that it is sent 2k times, and 0 indicates that it is not sent repeatedly). The length of this field is 2 bits.

[0355] (10) S / U: Indicates the uplink subcarrier of CFRA. 1 indicates supplementary uplink (SUL), and 0 indicates normal uplink (NUL).

[0356] (11)R: Reserved field.

[0357] Terminal devices can acquire the Channel State Information (CSI) of a candidate cell before or after cell handover and send the CSI to the network device. After the terminal device hands over to the candidate cell, the network device determines the transmission parameters of the candidate cell based on the CSI. Then, the network device transmits data with the terminal device based on the transmission parameters of the candidate cell. This improves data transmission performance after the terminal device hands over to the candidate cell. For example, currently, after the terminal device hands over to the candidate cell, the network device obtains channel state information through a traditional channel measurement process. The traditional channel measurement process introduces a significant CSI acquisition delay, causing the network device to be unable to use appropriate transmission parameters to transmit data with the terminal device within this delay, resulting in low data transmission performance. The above solution can solve this problem.

[0358] To accommodate transmission performance and UE measurement complexity, basic UE capabilities include: the terminal device measuring the reference signal of the candidate cell to obtain the CSI of the candidate cell before receiving the cell switch command (CSC), and then reporting the CSI of the candidate cell after receiving the cell switch command.

[0359] In the Layer 1 / L2 triggered mobility (LTM) project of release 19 (R19), it is proposed to support terminal devices in obtaining the signal quality and CSI of candidate cells through the channel status information reference signal (CSI-RS) of candidate cells, and sending the signal quality and CSI of the candidate cells to the network device. For example, the terminal device can report at least one of the following to the network device: CQI, PMI, CRI, SSBRI, layer indicator (LI), RI, layer 1 reference signal received power (L1-RSRP), layer 1 signal to interference plus noise ratio (L1-SINR), or codebook index i1.

[0360] For terminal devices, basic UE capabilities include measuring the reference signal of a candidate cell and reporting the measurement results after receiving cell handover signaling. Optional UE capabilities include measuring the reference signal of a candidate cell before receiving cell handover signaling and reporting the measurement results after receiving cell handover signaling.

[0361] The terminal device receives a reference signal from the network device. Then, the terminal device measures this reference signal to obtain a CSI. This CSI acquisition process involves CSI calculation, which occupies some processing units of the terminal device; these processing units are called CPUs in the communication protocol. The following describes the CPU time and number of CPUs required for a CSI report as specified in Release 15. The CPU time corresponding to a CSI report refers to the CPU time required for the terminal device to measure the reference signal and obtain the CSI report; or, the CPU time corresponding to a CSI report refers to the CPU time required for the terminal device to measure the reference signal, obtain the report, and report the CSI report. The number of CPUs corresponding to a CSI report refers to the number of CPUs required for the terminal device to measure the reference signal and obtain the CSI report; or, the number of CPUs corresponding to a CSI report refers to the number of CPUs required for the terminal device to measure the reference signal, obtain the report, and report the CSI report.

[0362] 1. When a report quantity is configured in the CSI report configuration (CSI-ReportConfig), meaning the report quantity (reportQuantity) in the CSI report configuration is not "None" (i.e., there is a reporting quantity), and the Channel State Information Reference Signal Resource Set (CSI-RSResourceSet) associated with this CSI report configuration is not configured to report Tracking Reference Signal Information (trs-info) via CSI, the Channel State Information Reference Signal Resource Set includes one or more CSI-RS resources. The CSI-RS resources in this Channel State Information Reference Signal Resource Set are used for channel state information acquisition.

[0363] 1. For non-periodic or semi-persistent CSI reports, the semi-persistent CSI report refers to the first CSI report triggered by the DCI and performed semi-persistently on the physical uplink shared channel (PUSCH). The CPU occupancy time starts from the first time domain symbol after the downlink resource (e.g., physical downlink control channel (PDCCH)) that triggers the CSI report and continues until the last time domain symbol of the reporting resource (e.g., PUSCH) carrying the CSI report. For example, as shown in Figure 7, the downlink resource that triggers the CSI report is the downlink resource occupied by the DCI, and the CPU occupancy time is from the first time domain symbol of the downlink resource occupied by the DCI to the last time domain symbol of the uplink resource carrying the CSI report.

[0364] 2. For periodically reported CSI reports or semi-persistently reported CSI reports, the semi-persistently reported CSI report refers to the first semi-persistently reported CSI report on the PUSCH, excluding the first CSI report triggered by DCI. As shown in Figure 8, the CPU usage time is from the first time domain symbol of the earliest reference signal resource in the candidate cell reference signal resources configured by the network device for the terminal device and no later than the CSI reference resource, to the last time domain symbol of the uplink resource carrying the CSI report.

[0365] 2. When no reporting quantity is configured in the CSI report configuration, that is, the reporting quantity (reportQuantity) in the CSI report configuration is None (i.e. there is no reporting quantity), and the Channel State Information Reference Signal Resource Set (CSI-RSResourceSet) associated with the CSI report configuration is not configured to report Tracking Reference Signal Information (trs-info) CSI.

[0366] 1. For semi-persistent reporting, the CSI report in semi-persistent reporting refers to the first CSI report on PUSCH that is semi-persistently reported except for the first CSI report triggered by DCI. As shown in Figure 9, the CPU time occupied is from the first time domain symbol of the earliest reference signal resource in the candidate cell reference signal resources configured by the network device for the terminal device to the Z3' time domain symbols after the last time domain symbol of the reference signal resource.

[0367] 2. For non-periodic reporting, the CPU usage time is the time interval [x, max(x+Z3, y+Z3')], where x is the first time-domain symbol after the PDCCH used to trigger CSI report reporting, y is the first time-domain symbol of the earliest appearing reference signal resource in the candidate cell reference signal resources configured by the network device for the terminal device, x+Z3 is the Z3 time-domain symbols after the first time-domain symbol after the first time-domain symbol after the PDCCH used to trigger CSI report reporting, and y+Z3' is the Z3' time-domain symbols after the first time-domain symbol of the earliest appearing reference signal resource in the candidate cell reference signal resources configured by the network device for the terminal device. That is, if x+Z3 is greater than y+Z3', the CPU usage time is from the first time-domain symbol after the PDCCH used to trigger CSI report reporting to the Z3 time-domain symbols after the first time-domain symbol after the PDCCH used to trigger CSI report reporting. If x+Z3 is less than y+Z3', the CPU time is from the first time domain symbol after the PDCCH used to trigger the CSI report to the Z3' time domain symbols after the first time domain symbol of the earliest reference signal resource in the candidate cell reference signal resources configured by the network device for the terminal device.

[0368] The definitions corresponding to Z3 and Z3' mentioned above are shown in Table 1 below, where Xμ is determined by the beam report timing capability parameter reported by the UE. KB l The beam switching timing capability parameters reported by the UE are determined.

[0369] Table 1

[0370] The number of CPUs used per CSI report is defined in R15 as follows:

[0371] If the report quantity in the Channel State Information Report Configuration (CSI-ReportConfig) is set to none (i.e., no reporting is configured), and Tracking Reference Signal Information (trs-Info) is configured in the Channel State Information Report Configuration, then the number of CPUs used by the CSI report is 0.

[0372] If the reported quantity in the Channel State Information Report configuration is configured as Channel State Information - Reference Signal Received Power (CRI-RSRP), Synchronization Signal Index - Reference Signal Received Power (SSB-Index-RSRP), Channel State Information - Signal-to-Interference-Noise Ratio (CRI-SINR), Synchronization Signal Index - Signal-to-Interference-Noise Ratio (SSB-Index-SINR), or none (in which case the Channel State Information Resource Set (CSI-RS-ResourceSet) is not configured with Tracking Reference Signal Information (TRS-Info)), then the number of CPUs occupied by the CSI report is 1.

[0373] If the reporting quantity in the Channel State Information Report configuration is configured as Channel State Information-Channel Rank Identifier-Precoding Matrix Identifier-Channel Quality Identifier (cri-RI-PMI-CQI), Channel State Information-Channel Rank Identifier-Codebook Index (cri-RI-i1), Channel State Information-Channel Rank Identifier-Codebook Index-Channel Quality Identifier (cri-RI-i1-CQI), Channel State Information-Channel Rank Identifier-Channel Quality Identifier (cri-RI-CQI), or Channel State-Channel Rank Identifier-Layer 1-Precoding Matrix Identifier-Channel Quality Identifier (cri-RI-LI-PMI-CQI), and if it is aperiodic reporting and meets certain conditions, then the number of CPUs occupied by the CSI report is the total number of CPUs reported by the UE, that is, the CSI report occupies all of the UE's CPUs. The conditions are as follows: the number of subcarriers in the PDCCH / CSI-RS / uplink is less than or equal to 3; the reporting resources carrying the CSI report do not carry transport blocks and / or hybrid automatic repeat request-acknowledge (HARQ-ACK) information; and the UE's CPU is not occupied. If the above conditions are not met, the number of CPUs occupied by the CSI report is equal to the number of CSI-RS resources associated with the CSI report.

[0374] However, how to define the CPU usage time and number of CPUs corresponding to the measurement reports of candidate cells to avoid CPU waste is a problem worth considering. This application provides a corresponding technical solution to specify the CPU information corresponding to the measurement reports of candidate cells, which helps to avoid CPU waste.

[0375] In this application, the signal quality may optionally include at least one of the following: reference signal received power (RSRP), signal to interference plus noise ratio (SINR), or reference signal received quality (RSRQ), and this application does not limit the specifics.

[0376] In this application, the terms HARQ-ACK, acknowledgement (ACK), feedback signaling, and hybrid automatic repeat request (HARQ) signaling can be used interchangeably.

[0377] The technical solution of this application is described below with reference to specific embodiments.

[0378] Figure 10 is a schematic diagram of an embodiment of the reference signal measurement and reporting method and the measurement report receiving method of this application. Referring to Figure 10, the method includes the following steps.

[0379] 1001. The network device sends one or more reference signal resources associated with the first reported configuration to the terminal device. Correspondingly, the terminal device receives one or more reference signal resources from the network device.

[0380] Here, the one or more reference signals are reference signal resources of one or more candidate cells of the terminal device. For details on the first reporting configuration, please refer to the relevant introduction below; it will not be elaborated upon here.

[0381] Step 1001 above can be alternatively described as follows: The network device sends reference signals corresponding to one or more reference signal resources associated with the first reporting configuration to the terminal device. Correspondingly, the terminal device receives reference signals corresponding to one or more reference signal resources from the network device. Here, the reference signals corresponding to one or more reference signal resources refer to the reference signals carrying those one or more reference signal resources.

[0382] Optionally, the reference signal may be a channel state information reference signal (CSI-RS) or an SSB. It should be noted that this reference signal is a downlink signal; please refer to the aforementioned introduction for information on downlink signals.

[0383] Optionally, the embodiment shown in FIG10 further includes step 1001a. Step 1001a may be performed before step 1001.

[0384] 1001a. The network device sends the first configuration information. Correspondingly, the terminal device receives the first configuration information.

[0385] The first configuration information is used to indicate the first reporting configuration, which is used to configure the acquisition of CSI-related information for one or more candidate cells.

[0386] In one possible implementation, the reporting quantity configured in the first reporting configuration includes parameters used to characterize the downlink channel state. For example, if the reporting quantity configured in a reporting configuration includes at least one of PMI, RI, LI, CQI, and i1, then the first reporting configuration is used for reporting the CSI of one or more candidate cells.

[0387] In another possible implementation, the first reporting configuration is associated with one or more reference signal resources. These one or more reference signal resources are used for candidate cell CSI acquisition, thus the first reporting configuration is used for reporting the CSI of one or more candidate cells. Alternatively, the reference signal resources associated with the first reporting configuration are not associated with a repetition parameter or a tracking reference signal information (trs-info) parameter. The repetition parameter indicates that the reference signal resource is used for beam management measurements, and the trs-info parameter indicates that the reference signal resource is used for timing tracking acquisition. When a reference signal resource is not associated with either parameter, it indicates that the reference signal resource is used for CSI acquisition.

[0388] Optionally, the first reporting configuration can be an L1 / L2 triggered Mobility-Channel State Information-Report Configuration (LTM-CSI-ReportConfig).

[0389] Optionally, the first reported configuration associates reference signal resources of one or more candidate cells. This will be described in detail below.

[0390] Scenario 1: The first reported configuration is associated with the reference signal resources of a candidate cell. The first configuration information includes the reference signal resources of the candidate cell. Optionally, the first configuration information includes the identifier of the candidate cell.

[0391] Optionally, the first reported configuration may be associated with a reference signal resource of a candidate cell. Alternatively, the first reported configuration may be associated with one or more reference signal resources of a candidate cell.

[0392] In one possible implementation, the first reporting configuration can be configured in the mobility-candidate (LTM-Candidate) triggered by cell L1 / L2, and the reference signal resources associated with the first reporting configuration belong to the candidate cell corresponding to the mobility-candidate cell identifier (LTM-CandidateId) triggered by L1 / L2 in the cell LTM-Candidate. In this implementation, the first configuration information includes the reference signal resources of the candidate cell.

[0393] In another possible implementation, the first reporting configuration can be in the Cell Channel State Information - Measurement Configuration (CSI-MeasConfig), that is, the first reporting configuration is included in the configuration information of the serving cell of the terminal device. The first reporting configuration needs to additionally configure an L1 / L2 triggered Mobility-Candidate Cell Id (LTM-CandidateId), which indicates the candidate cell to which the reference signal resource associated with the first reporting configuration belongs. In this implementation, the first configuration information includes the reference signal resource of the candidate cell and the identifier of the candidate cell.

[0394] Scenario 2: The first reported configuration associates reference signal resources of multiple candidate cells. The first configuration information includes the reference signal resources of multiple candidate cells and the identifier of the candidate cell corresponding to each reference signal resource.

[0395] In one possible implementation, the first reporting configuration is associated with a reference signal resource for each of one or more candidate cells.

[0396] In another possible implementation, the first reporting configuration is associated with one or more reference signal resources for each of the one or more candidate cells.

[0397] In scenario two, the first reporting configuration can be configured in the cell CSI-MeasConfig. The first reporting configuration needs to specify the candidate cell identifier (LTM-CandidateId) for each reference signal resource. For example, the first reporting configuration includes a reference signal resource index list and a candidate cell identifier list. The reference signal resource indices in the reference signal resource index list correspond one-to-one with the candidate cell identifiers in the candidate cell identifier list. For example, the reference signal resource index list includes reference signal resource index 1, reference signal resource index 2, and reference signal resource index 3. The candidate cell identifier list includes candidate cell identifier 1, candidate cell identifier 2, and candidate cell identifier 1. Therefore, the candidate cells corresponding to the reference signal resource index 1 and reference signal resource index 3 are the candidate cells corresponding to candidate cell identifier 1, respectively. The candidate cell corresponding to reference signal resource index 2 is the candidate cell corresponding to candidate cell identifier 2.

[0398] In this implementation, a method for configuring reference signal resources is provided for cases with one candidate cell and multiple candidate cells. The reference signal resources can be associated with the identifiers of the candidate cells, thereby identifying each reference signal resource.

[0399] It should be noted that the first reported configuration can also be associated with the reference signal resources of other cells. For example, the first reported configuration can be associated with the reference signal resources of the serving cell.

[0400] Optionally, the first configuration information is also used to indicate the reference signal resource configuration associated with the first reporting configuration. The reference signal resource configuration includes one or more reference signal resources associated with the first reporting configuration. This facilitates the terminal device in measuring the reference signal resources in the reference signal resource configuration to obtain the measurement results corresponding to the first reporting configuration. In other words, it enables channel measurement of candidate cells. For example, the reference signal resource configuration can be configured in Cell Channel State Information - Measurement Configuration (CSI-MeasConfig) or L1 / L2 triggered Mobility-Candidate Cell (LTM-Candidate). For example, the reference signal resource configuration includes a reference signal resource index list and a candidate cell identifier list. The reference signal resource indices in the reference signal resource index list correspond one-to-one with the candidate cell identifiers in the candidate cell identifier list.

[0401] It should be noted that the one or more reference signal resources associated with the first reported configuration mentioned above can also be configured using other information, and this application does not impose any restrictions on this. In other words, the first reported configuration can be configured together or separately, and this application does not impose any restrictions on this.

[0402] The above is an example of configuring the first reporting configuration with the first configuration information. The first configuration information can also be configured with more reporting configurations, which are not limited in this application.

[0403] The embodiment shown in Figure 10 also includes step 1000. Step 1000 may be performed before step 1001.

[0404] 1000. The terminal device sends capability information to the network device. Correspondingly, the network device receives the capability information from the terminal device.

[0405] The capability information includes at least one of the following: whether the terminal device supports CSI acquisition of candidate cells, or the candidate cell CSI acquisition methods supported by the terminal device. Candidate cell CSI acquisition methods include CSI acquisition method one and CSI acquisition method two. CSI acquisition method one includes: after cell handover signaling, the terminal device measures the reference signal of the candidate cell and reports the measurement results. In other words, CSI acquisition method one includes: after cell handover, the terminal device measures the reference signal of the candidate cell and reports the measurement results, or, after cell handover signaling, the terminal device measures the reference signal of the candidate cell. CSI acquisition method two includes: before cell handover signaling, the terminal device measures the reference signal of the candidate cell, and after cell handover signaling, the terminal device reports the measurement results. In other words, CSI acquisition method two includes: the terminal device measuring the reference signal of the candidate cell before cell handover, and the terminal device reporting the measurement results of the candidate cell after cell handover, or, the terminal device measuring the reference signal of the candidate cell before cell handover signaling.

[0406] In this implementation, the terminal device can also send capability information to the network device, thereby facilitating the network device to reasonably configure reference signal resources and report configurations for the terminal device. This enables the terminal device to measure and report reference signals for candidate cells.

[0407] Specifically, terminal devices can report the candidate cell CSI acquisition methods they support through terminal capability parameters. For example, a terminal device can report CSI acquisition method one and / or CSI acquisition method two that it supports through one or more terminal capability parameters.

[0408] In one possible implementation, if the capability information includes support for CSI acquisition of candidate cells by the terminal device, then the terminal device is assumed to support CSI acquisition method one by default. If the capability information includes support for CSI acquisition of candidate cells by the terminal device, then the terminal device is assumed to support CSI acquisition method two by default.

[0409] In another possible implementation, if the capability information includes CSI acquisition method two supported by the terminal device, then the terminal device is assumed to support both CSI acquisition method one and CSI acquisition method two.

[0410] Among the two implementation methods described above, when the capability information contains different content, this section outlines some possible ways to interpret the capabilities possessed by the terminal device. This approach helps reduce the signaling overhead for indicating capabilities by the terminal device.

[0411] It should be noted that, in one possible implementation, if the terminal device reports the capability information, it indicates that the terminal device supports the capability indicated by the capability information. If the terminal device does not report the capability information, it indicates that the terminal device does not support the capability indicated by the capability information. In another possible implementation, if the terminal device reports the capability information, it indicates that the terminal device supports the capability indicated by the capability information. If the terminal device reports that it does not support the capability indicated by the capability information, it indicates that the terminal device does not support the capability indicated by the capability information. In yet another possible implementation, if the terminal device supports some capabilities indicated by the aforementioned capability information, then the terminal device must support other capabilities indicated by the capability information; that is, if the terminal device does not report some of these other capabilities, it also indicates that the terminal device supports these other capabilities. This application does not impose any specific limitations on this.

[0412] Optionally, the embodiment shown in FIG10 further includes step 1001b. Step 1001b may be performed before step 1002.

[0413] 1001b. The network device sends the second configuration information. Correspondingly, the terminal device receives the second configuration information.

[0414] The second configuration information indicates the candidate cell CSI acquisition method used by the terminal device. CSI acquisition methods include CSI acquisition method one and CSI acquisition method two. For details on CSI acquisition method one and CSI acquisition method two, please refer to the aforementioned introductions; they will not be repeated here.

[0415] Specifically, the network device is configured to use either CSI acquisition method one or CSI acquisition method two to measure and / or report the reference signals of candidate cells. If the network device is configured to use CSI acquisition method one, the terminal device measures the reference signals of candidate cells using CSI acquisition method one and reports the measurement results. If the network device is configured to use CSI acquisition method two, the terminal device measures the reference signals of candidate cells using CSI acquisition method two and reports the measurement results.

[0416] In this implementation, the terminal device receives instructions from the network device regarding the candidate cell CSI acquisition method, facilitating cooperation with the network device in measuring and reporting the reference signals of the candidate cells. This ensures alignment between the terminal device and the network device, enabling the acquisition of measurement results for the candidate cells.

[0417] It should be noted that there is no fixed execution order between steps 1001b and 1001, and this application does not impose any restrictions on the specific execution order. For example, step 1001b may be executed first, followed by step 1001; or step 1001 may be executed first, followed by step 1001b; or, depending on the circumstances, steps 1001b and 1001 may be executed simultaneously, and this application does not impose any restrictions on the specific execution order.

[0418] It should be noted that if the embodiment shown in Figure 10 further includes step 1001a, there is no fixed execution order between steps 1001a and 1001b, and this application does not impose any specific restrictions. For example, step 1001a can be executed first, followed by step 1001b; or step 1001b can be executed first, followed by step 1001a; or, depending on the circumstances, steps 1001a and 1001b can be executed simultaneously, and this application does not impose any specific restrictions.

[0419] It should be noted that if the embodiment shown in Figure 10 further includes step 1000, step 1001b can be performed after step 1000.

[0420] The above, step 1001b, describes a scheme for configuring the network device to use the corresponding CSI acquisition method to measure and / or report the reference signal of the candidate cell. In practical applications, the network device may not need to configure the candidate cell CSI acquisition method used by the terminal device. For example, if the terminal device supports CSI acquisition method two, then the terminal device uses CSI acquisition method two to measure the reference signal of the candidate cell and report the measurement results. If the terminal device does not support CSI acquisition method two, that is, the terminal device only supports CSI acquisition method one, then the terminal device uses CSI acquisition method one to measure the reference signal of the candidate cell and report the measurement results. In other words, if the terminal device uses CSI acquisition method one to measure the reference signal of the candidate cell and report the measurement results, it can be understood that: the terminal device only supports CSI acquisition method one, or the network device is configured to use CSI acquisition method one. If the terminal device uses CSI acquisition method two to measure the reference signal of the candidate cell and report the measurement results of the candidate cell, then it can be understood that the terminal device supports CSI acquisition method two, or the network device is configured to use CSI acquisition method two for the terminal device.

[0421] Optionally, when the terminal device supports both CSI acquisition method one and CSI acquisition method two, the network device configures the candidate cell CSI acquisition method adopted by the terminal device through the aforementioned second configuration information.

[0422] In summary, the candidate cell CSI acquisition method adopted by the terminal device can be determined by at least one of the following: network device configuration or instruction, and terminal capabilities.

[0423] 1002. The terminal device measures one or more reference signal resources associated with the first reported configuration and obtains a measurement report.

[0424] The reference signal resources refer to the reference signal resources of one or more candidate cells. The measurement report includes the measurement results of the one or more candidate cells. The measurement results for each candidate cell include parameters used to characterize the downlink channel state. For example, the measurement results for each candidate cell include at least one of CQI, RI, and PMI.

[0425] 1003. The terminal device sends a measurement report to the network device. Correspondingly, the network device receives the measurement report from the terminal device.

[0426] The measurement report corresponds to the first CPU information, which includes CPU usage time and / or the number of CPUs.

[0427] In one possible implementation, CPU occupancy time refers to the CPU occupancy time required for the terminal device to obtain the measurement report by measuring the reference signal resources. The number of CPUs refers to the number of CPUs required for the terminal device to obtain the measurement report by measuring the reference signal resources.

[0428] In another possible implementation, CPU occupancy time refers to the CPU time required for the terminal device to obtain the reference signal resources and report the measurement report. The number of CPUs refers to the number of CPUs required for the terminal device to obtain the reference signal resources and report the measurement report.

[0429] In another possible implementation, CPU usage time refers to the CPU time required for the terminal device to complete the measurement report submission. The number of CPUs refers to the number of CPUs required for CSI calculations performed after obtaining the measurement report.

[0430] Optionally, the embodiment shown in FIG10 further includes step 1002a.

[0431] 1002a. The network device sends the first signaling message to the terminal device. Correspondingly, the terminal device receives the first signaling message from the network device.

[0432] The first signaling is used to instruct the terminal device to hand over to the target cell, which is one of the candidate cells among the one or more candidate cells. Optionally, the first signaling may be called cell handover signaling, or handover signaling, etc., and this application does not limit the specific terminology.

[0433] The following describes two possible implementations of the execution order between step 1002a and step 1002.

[0434] Implementation Method 1, Step 1002a is executed before Step 1002. That is, before the terminal device measures one or more reference signal resources associated with the first reported configuration, the terminal device receives the first signaling. Specifically, the terminal device uses the CSI acquisition method to measure the reference signals of candidate cells and reports the measurement results.

[0435] Optionally, the CPU usage time is the time between the first moment after the first duration and the second moment after the fourth duration. In other words, the start time of the CPU usage time is the time between the first moment after the first duration, and the end time of the CPU usage time is the time between the second moment after the fourth duration.

[0436] It should be noted that both the first and second durations can be configured or indicated by the network device, reported by the terminal capability, or determined by any one or more methods specified by the communication protocol. For example, both the first and second durations can be time offsets configured by the network device. As another example, if both the first and second durations are 0, the start time of CPU usage is the first moment, without needing to add any extra duration. The end time of CPU usage is the second moment, also without needing to add any extra duration. Therefore, the CPU usage time is the time between the first and second moments. Alternatively, both the first and second durations can be configured by the network device for the terminal device based on the terminal capability report. For example, the terminal device reports a supported minimum first duration and a minimum second duration. The network device configures the first duration for the terminal device based on the minimum first duration and the second duration based on the minimum second duration. Where the first duration is greater than or equal to the minimum first duration, and the second duration is greater than or equal to the minimum second duration.

[0437] Optionally, the units corresponding to the first duration and the second duration can be frames, subframes, time slots, time domain symbols, milliseconds, seconds, etc., and this application does not limit the specific units.

[0438] The following section introduces some possible implementation methods for the first moment.

[0439] Optionally, the first moment includes any of the following:

[0440] 1. The terminal device receives the scheduling information at the designated time. The scheduling information is used to schedule the downlink channel carrying the first signaling. Optionally, in this implementation, the embodiment shown in Figure 10 above further includes step 1002b. Step 1002b can be performed before step 1002a.

[0441] 1002b. The network device sends scheduling information to the terminal device. Correspondingly, the terminal device receives the scheduling information from the network device.

[0442] For example, the scheduling information is carried in the DCI. The first time is the first time domain symbol after the PDCCH occupied by the DCI, or the first time is the first or last time domain symbol of the PDCCH occupied by the DCI.

[0443] It should be noted that there is no fixed execution order between step 1002b and step 1001, and this application does not impose any restrictions on the specific execution order. For example, step 1002b may be executed first, followed by step 1001; or step 1001 may be executed first, followed by step 1002b; or, depending on the circumstances, steps 1002b and 1001 may be executed simultaneously, and this application does not impose any restrictions on the specific execution order.

[0444] It should be noted that if the embodiment shown in Figure 10 further includes steps 1000, 1001a and 1001b, there is no fixed execution order between step 1002b and steps 1000, 1001a and 1001b, and this application does not impose any specific restrictions.

[0445] 2. The reception time of the first signaling received by the terminal equipment. For example, the first time is the first time domain symbol after the physical downlink shared channel (PDSCH) carrying the first signaling, or the first or last time domain symbol of the PDSCH carrying the first signaling.

[0446] 3. The timing of sending the feedback signaling corresponding to the first signaling by the terminal device. Optionally, in this implementation, the embodiment shown in Figure 10 above further includes step 1002c. Step 1002c can be executed after step 1002a.

[0447] 1002c. The terminal device sends a feedback signaling message to the network device. Correspondingly, the network device receives the feedback signaling message from the terminal device.

[0448] The feedback signaling is an ACK for the feedback of the first signaling, used to indicate that the terminal device has received the first signaling.

[0449] Specifically, the first time-domain symbol is the first time-domain symbol after the terminal device sends the PUSCH or physical uplink control channel (PUCCH) carrying the first signaling feedback for the PDSCH (where PUSCH is a PUSCH carrying HARQ-ACK and PUCCH is a PUCCH carrying HARQ-ACK), or the first or last time-domain symbol of the PUSCH or PUCCH carrying the first signaling feedback for the PDSCH (where PUSCH is a PUSCH carrying HARQ-ACK and PUCCH is a PUCCH carrying HARQ-ACK).

[0450] 4. The time at which the terminal device sends the feedback signaling corresponding to the first signaling is equal to the second duration, where the second duration is a preset duration. The second duration can be the time required for the first signaling to take effect. For example, the second duration is 3ms. Specifically, the first time is the time at which the terminal device sends the PUSCH or PUCCH (where the PUSCH carries HARQ-ACK or the PUCCH carries HARQ-ACK) for the PDSCH feedback carrying the first signaling, plus 3ms. Alternatively, the first time is the first time-domain symbol at which the terminal device sends the PUSCH or PUCCH (where the PUSCH carries HARQ-ACK or the PUCCH carries HARQ-ACK) for the PDSCH feedback carrying the first signaling, plus 3ms. It should be noted that the time at which the terminal device sends the feedback signaling corresponding to the first signaling is equal to the second duration can also be called the effective time of the first signaling.

[0451] 5. The time at which the terminal device sends the feedback signaling corresponding to the first signaling exceeds the time interval of the second and third durations, where the third duration is the duration of the target cell handover interruption. Please refer to the preceding description for the second duration. Alternatively, the time at which the terminal device sends the feedback signaling corresponding to the first signaling exceeds the time interval of the third duration.

[0452] The following describes some possible implementations of the third duration. Optionally, the third duration may be determined by at least one of the following:

[0453] a. The time it takes for the terminal device to parse the configuration information of the target cell. For example, this time is T. LTM-RRC-processing T LTM-RRC-processing The time required for decoding the abstract syntax notation 1 (ASN.1) and performing validity / consistency checks on the configuration information of the target cell indicated in the first signaling. LTM-RRC-processingIt can be 0 or 10ms. Refer to the communication protocol TS 38.133 for the specific value to use.

[0454] b. The time taken for the terminal device to process the configuration information of the target cell. For example, this time is T. LTM-processing T LTM-processing The processing time for the UE includes the time for applying target cell parameters and the time for layer 1 (L1) / layer 2 (L2) changes. LTM- For specific values ​​and definitions of processing, refer to the communication protocol TS 38.133.

[0455] c. The time required for the terminal device to accurately track the target cell and obtain its timing information. This time is T. first- RS T first-RS It can be 0, or it can be 3ms after the feedback signaling is sent, the time when the target cell sends the first SSB.

[0456] d. SSB processing time of the terminal device for the target cell.

[0457] Specifically, if the first signaling indicates a TCI state, but that TCI state has not been activated beforehand or has been activated for too long, the terminal device needs to re-receive the SSB of the target cell to obtain synchronization information. This can be understood as the terminal device's processing time for the SSB of the target cell. This time is T. RS-pro T RS-pro It can be 0 or 2ms. Refer to the communication protocol TS 38.133 for details.

[0458] Specifically, the first moment is the time when the terminal device sends the PUSCH or PUCCH (which carries HARQ-ACK in the PUSCH or PUCCH) in response to the PDSCH carrying the first signaling, plus the second and third durations. Alternatively, the first moment is the first time-domain symbol after adding the second and third durations to the time when the terminal device sends the PUSCH or PUCCH (which carries HARQ-ACK in the PUSCH or PUCCH) in response to the PDSCH carrying the first signaling.

[0459] 6. The moment when the target cell handover is completed.

[0460] For example, the time when the target cell handover is completed is the time when the terminal device sends the first uplink message (first UL message) in the target cell. As another example, for target cell handover using a random access channel (RACH) procedure, the time when the target cell handover is completed is the time when the RACH procedure is completed. Yet another example is the time when the terminal device sends the cell reconfiguration completion message.

[0461] 7. The time at which the first time domain unit of the first reference signal resource after the reception time of the first signaling is located in the first reported configuration associated reference signal resource.

[0462] For example, the first time-domain symbol of the first reference signal resource associated with the first reporting configuration at the first moment, after the reception time of receiving the first signaling. Or, the first time-domain symbol of the earliest (or most recent) reference signal resource associated with the first reporting configuration at the first moment, after the reception time of receiving the first signaling.

[0463] The above item 7 can be replaced by describing it as: the time of the first time domain unit of the first reference signal resource in the target cell associated with the first reporting configuration, after the reception time of the first signaling.

[0464] 8. The time at which the first time domain unit of the first reference signal resource after the effective time of the first signaling is located in the first reported configuration associated reference signal resource.

[0465] For example, the first time-domain symbol of the first reference signal resource associated with the first reporting configuration at the first moment, after the effective time of the first signaling. Or, the first time-domain symbol of the earliest (or most recent) reference signal resource associated with the first reporting configuration at the first moment, after the effective time of the first signaling.

[0466] The effective time of the first signaling can be understood as the time when the terminal device sends the feedback signaling corresponding to the first signaling plus the time when 3ms is located. For details, please refer to the description in item 4 above.

[0467] The above item 8 can be replaced by describing it as: the time when the first time domain unit of the first reference signal resource after the first signaling takes effect in the reference signal resources associated with the first reported configuration; or, the time when the first time domain unit of the first reference signal resource after the first signaling takes effect in the reference signal resources of the target cell associated with the first reported configuration.

[0468] This implementation method limits some possible implementations for the first moment. This helps to reasonably define the start time of CPU usage and avoids wasting CPU time on terminal devices.

[0469] The following describes some possible implementations of the second time step. Optionally, the second time step may include any of the following:

[0470] 1. The time of the last time domain unit occupied by the uplink resources carrying the measurement report. The reporting resources can be PUSCH or PUCCH resources.

[0471] In one possible implementation, the uplink resource carrying the measurement report is a PUSCH resource scheduled by the DCI or random access response (RAR) uplink grant sent by the network device, and the second time is the last time domain symbol of the PUSCH resource.

[0472] In another possible implementation, the uplink resource carrying the measurement report is the PUSCH resource in message A (message A, Msg A), and the second time is the last time domain symbol of that PUSCH resource.

[0473] In another possible implementation, the uplink resource carrying the measurement report is either the PUCCH resource or the PUSCH resource indicated in the first signaling. The second time point is either the last time-domain symbol of the PUSCH resource or the last time-domain symbol of the PUCCH resource.

[0474] In another possible implementation, the uplink resource carrying the measurement report is a reporting resource timing within a pre-configured reporting resource. In this implementation, the network device pre-configures reporting resources for the terminal device, and these pre-configured reporting resources include multiple reporting resource timings. One of these multiple reporting resource timings is used to carry the measurement report. That is, the second time point is the last time-domain symbol of the reporting resource timing carrying the measurement report.

[0475] 2. The time of the last time domain unit of the last reference signal resource in the first reported configuration associated reference signal resource before the target cell handover is completed.

[0476] For example, the last time-domain symbol of the last reference signal resource in the reference signal resource associated with the first reported configuration at the second moment, before the handover of the target cell is completed.

[0477] 3. Among the reference signal resources associated with the first reported configuration, the time is no later than the time of the last time domain unit occupied by the last reference signal resource of the CSI reference resources before the handover of the target cell is completed.

[0478] For example, the second time moment is the last time domain symbol of the last reference signal resource in the reference signal resource associated with the first reported configuration, which is no later than the last reference signal resource of the CSI reference resource before the target cell handover is completed.

[0479] 4. In the reference signal resources associated with the first reported configuration, the time is the time after the last time domain unit of the last reference signal resource before the target cell handover is completed, plus N time domain units, where N is an integer greater than or equal to 1.

[0480] For example, the second time-domain symbol is the last time-domain symbol of the last reference signal resource before the target cell handover is completed, plus N time-domain symbols, which is associated with the reference signal resource of the first reported configuration.

[0481] Optionally, the value of N is determined by at least one of the communication protocol, network device configuration, and terminal capabilities. For example, the value of N may be determined based on the terminal capabilities. For example, N = Z3'.

[0482] 5. The time at which the last time domain unit of the last reference signal resource associated with the first reported configuration is located, no later than the last time domain unit of the last reference signal resource of the CSI reference resource plus N time domain units before the target cell handover is completed, where N is an integer greater than or equal to 1.

[0483] For example, the second time-domain symbol is the last time-domain symbol of the last reference signal resource that is no later than the last CSI reference resource before the target cell handover is completed, which is the reference signal resource associated with the first reported configuration. It is the time-domain symbol containing N time-domain symbols.

[0484] 6. The time it takes for the target cell handover to be completed.

[0485] Please refer to the aforementioned introduction for the time when the target cell handover is completed; it will not be repeated here.

[0486] This implementation method limits some possible implementations for the second time step. This helps to reasonably define the end time of CPU usage and avoids wasting CPU time on terminal devices.

[0487] Based on the above implementation methods for the start and end times of CPU usage time, some possible combinations are given below. The following combinations are introduced with the first duration and the second duration both being 0 as an example.

[0488] In combination mode 1, the CPU usage time is defined as the time between the moment the terminal device receives the first signaling and the moment when the last time domain element occupied by the uplink resources carrying the measurement report is located. Alternatively, the CPU usage time is defined as the time between the first time domain symbol after the PDSCH carrying the first signaling and the last time domain symbol occupied by the uplink resources carrying the measurement report. For example, in combination mode 1 as shown in Figure 11, where the first signaling is cell handover signaling, the CPU usage time is defined as the time between the first or last time domain symbol of the PDSCH carrying the cell handover signaling and the last time domain symbol occupied by the uplink resources carrying the measurement report.

[0489] In combination method two, the CPU usage time is: the time between the time when the terminal device sends the feedback signaling corresponding to the first signaling plus the second duration, and the time when the last time domain unit occupied by the reporting resources of the bearer measurement report is located. Alternatively, the CPU usage time is: the time between the time when the feedback signaling corresponding to the first signaling plus 3ms, and the time when the last time domain symbol is located, and the last time domain symbol occupied by the reporting resources of the bearer measurement report. For example, in combination method two as shown in Figure 11, the first signaling is cell handover signaling, and the feedback signaling corresponding to the cell handover signaling is ACK. The CPU usage time is: the time between the time when ACK is sent plus 3ms, and the time when the last time domain symbol is located, and the last time domain symbol occupied by the reporting resources of the bearer measurement report.

[0490] Combination Method 3: The CPU occupied time is: the time between the first time domain unit of the first reference signal resource associated with the first reporting configuration after the first signaling takes effect and the time between the last time domain unit occupied by the resource carrying the measurement report. Alternatively, the CPU occupied time is: the time between the first time domain unit of the first reference signal resource associated with the first reporting configuration, 3ms after the transmission time of the feedback signaling corresponding to the first signaling, and the time between the last time domain unit occupied by the resource carrying the measurement report. Or, the CPU occupied time is: the time between the first time domain unit of the earliest reference signal resource, 3ms after the last time domain symbol of the HARQ-ACK feedback signaling corresponding to the cell handover signaling, and the last time domain unit occupied by the resource carrying the measurement report. The English translation of this implementation method is: The occupied CPU can be from the first symbol of the earliest CSI-RS resource after 3ms of the last symbol of HARQ-ACK information for the CSC until the last symbol of the UL resource carrying the report. For example, in combination mode 3 as shown in Figure 11, the first signaling is cell handover signaling. The effective time of cell handover signaling is the time when the ACK corresponding to cell handover signaling is sent plus the time domain symbol where 3ms is located. The CPU time occupied is the time from the first time domain symbol of the first reference signal resource (i.e., reference signal resource 1 shown in Figure 11) after the effective time of the first signaling to the last time domain symbol occupied by the reporting resource of the bearer measurement report.

[0491] In combination mode four, the CPU usage time is the time between the first time domain unit after adding the second duration to the time when the terminal device sends the feedback signaling corresponding to the first signaling, and the time when the last time domain unit occupied by the reporting resources of the bearer measurement report is located. For example, in combination mode four as shown in Figure 11, the CPU usage time is the time from the time when the feedback signaling corresponding to the first signaling (i.e., ACK in Figure 11) is sent, plus the first time domain symbol after 3ms, to the last time domain symbol occupied by the reporting resources of the bearer measurement report.

[0492] Implementation Method Two, Step 1002b, is executed after Step 1002. Before the terminal device receives the first signaling, the terminal device measures one or more reference signal resources associated with the first reported configuration. Then, after receiving the first signaling, the terminal device reports a measurement report. That is, the terminal device uses CSI acquisition method two to measure the reference signals of the candidate cells and reports the measurement results of the candidate cell reference signals.

[0493] Optionally, the CPU usage time is the time between the moment when the third time interval has elapsed for five seconds and the moment when the fourth time interval has elapsed for six seconds. In other words, the CPU usage time begins at the moment when the third time interval has elapsed for five seconds and ends at the moment when the fourth time interval has elapsed for six seconds.

[0494] The fifth duration is similar to the first duration mentioned above; please refer to the relevant introduction to the first duration for details. The sixth duration is similar to the second duration mentioned above; please refer to the relevant introduction to the second duration for details, which will not be repeated here. If both the fifth and sixth durations are 0, the CPU usage time is the time between the third and fourth time points.

[0495] The following section introduces some possible implementations of the third time step.

[0496] Optionally, the third time interval includes any of the following:

[0497] 1. The time at which the first time domain unit occupied by the first reference signal resource in each of the one or more reference signal resource periods associated with the first reported configuration is located, prior to the receipt of the first signaling. Alternatively, the time at which the first time domain unit occupied by the first reference signal resource in one or more reference signal resource periods associated with the first reported configuration is located, prior to the receipt of the first signaling.

[0498] For example, the third moment is: the first time domain symbol or the first time slot occupied by the first reference signal resource in each reference signal resource cycle before receiving the first signaling, within one or more reference signal resource cycles in which the first reported configuration associated reference signal resource is located.

[0499] Optionally, the time of the first time domain unit occupied by the first reference signal resource in each reference signal resource period after the reference signal resource associated with the first reported configuration takes effect and before the first signaling is received.

[0500] In one possible implementation, the first reporting configuration is associated with the reference signal resources of one candidate cell, or the first reporting configuration is associated with the reference signal resources of multiple candidate cells, wherein the reference signal resources of each candidate cell have the same reference signal resource period.

[0501] In another possible implementation, the first reported configuration associates reference signal resources of multiple candidate cells, taking the reference signal resource with the largest reference signal resource period among the multiple candidate cells as the standard, and the third time is the time when the first time domain unit occupied by the first reference signal resource in each reference signal resource period of the reference signal resource with the largest reference signal resource period is located.

[0502] In this implementation, the CPU time consumed includes P time periods, where P is the number of reference signal resource cycles in which the reference signal resources associated with the first reported configuration are located before receiving the first signaling. For example, as shown in Figure 12A, the reference signal resources associated with the first reported configuration before receiving cell handover signaling include reference signal resource 1, reference signal resource 2, and reference signal resource 3. Therefore, the P time periods include time period 1, time period 2, and time period 3. The start time of time period 1 is the first time-domain symbol of reference signal resource 1 in the first cycle. The start time of time period 2 is the first time-domain symbol of reference signal resource 1 in the second cycle. The start time of time period 3 is the first time-domain symbol of reference signal resource 1 in the third cycle.

[0503] 2. The time when the first time domain unit occupied by the first reference signal resource in the first reported configuration associated reference signal resource is located.

[0504] For example, the third time point is the first time domain symbol or the first time slot occupied by the first reference signal resource in the first reported configuration associated reference signal resource. As shown in Figure 13, the first reported configuration associated reference signal resources include reference signal resources 1 to reference signal resources 3. Reference signal resource 1 is the first reference signal resource in the first reported configuration associated reference signal resource. The start time of CPU occupancy is the first time domain symbol of reference signal resource 1.

[0505] 3. The time when the first time domain unit occupied by the first reference signal resource after the first reported configuration associated reference signal resource takes effect.

[0506] Specifically, the network device instructs the terminal device to report the reference signal resources associated with the first configuration, and the reference signal resources associated with the first configuration take effect when the corresponding conditions are met.

[0507] In one possible implementation, the reference signal resources associated with the first reported configuration include the reference signal resources of the candidate cell. The first reference signal resource after the first reported configuration associated reference signal resources take effect includes: the reference signal resources of the candidate cell taking effect after the terminal device reports the beam measurement results of the candidate cell; or, the reference signal resources of the candidate cell taking effect if the signal quality of at least one reference signal in the beam measurement results reported by the terminal device is among the top K positions, where K is an integer greater than or equal to 1; or, the signal quality of at least one reference signal in the beam measurement results reported by the terminal device is greater than the signal quality of the current beam of the serving cell. The current beam is the beam corresponding to the quasi-colocation type (QCL type D) in the current transmission configuration indicator state (TCI state) indicated by the serving cell; or, the signal quality of at least one reference signal in the beam measurement results reported by the terminal device is greater than the signal quality obtained by currently measuring the reference signal of the serving cell.

[0508] In another possible implementation, the network device sends a second signaling message to the terminal device. This second signaling message is used to activate the reference signal resource associated with the first reported configuration. Please refer to the relevant description below for details on the second signaling message. Therefore, the reference signal resource associated with the first reported configuration becomes effective. For example, as shown in Figure 14, the second signaling message is an activation signaling message. The start time of the CPU occupancy is the first time-domain symbol of the first reference signal resource (i.e., reference signal resource 1) after the terminal device receives the activation signaling message, or it can be the first time-domain symbol of the first reference signal resource after the activation signaling message becomes effective. The activation signaling message becoming effective can be described as the effective time of the activation signaling message. The effective time of the activation signaling message is the time when the terminal device sends the feedback signaling message corresponding to the activation signaling message plus the time containing 3ms.

[0509] 4. The timing of receiving the second signaling by the terminal device.

[0510] The second signaling is used to activate some or all of the reference signal resources associated with the first reported configuration. For example, the second signaling is MAC CE.

[0511] Optionally, the reception time of the second signaling can be the time when the terminal device receives the first or last time-domain symbol of the PDSCH carrying the second signaling. Alternatively, the reception time of the second signaling can be the first time-domain symbol after receiving the PDSCH carrying the second signaling. For example, as shown in Figure 14, the second signaling is an activation signaling. The start time of CPU occupancy is the time when the terminal device receives the last time-domain symbol of the PDSCH carrying the activation signaling.

[0512] In this implementation, the reference signal resource associated with the first reported configuration is a semi-persistent reference signal resource.

[0513] 5. The effective time of the second signaling.

[0514] In this implementation, the reference signal resource associated with the first reported configuration is a semi-persistent reference signal resource.

[0515] Optionally, the effective time of the second signaling is the transmission time of the feedback signaling corresponding to the second signaling. The feedback signaling corresponding to the second signaling is used to indicate that the terminal device has received the second signaling. For example, the effective time of the second signaling is the first time-domain symbol after the PUSCH or PUCCH that provides feedback to the PDSCH carrying the second signaling. Alternatively, the effective time of the second signaling is the first or last time-domain symbol of the PUSCH or PUCCH that provides feedback to the PDSCH carrying the second signaling. The PUSCH or PUCCH carries the feedback signaling corresponding to the second signaling. For example, as shown in Figure 15, the start time of CPU occupancy is the transmission time of the feedback signaling corresponding to the second signaling.

[0516] Optionally, the effective time of the second signaling is the time when the feedback signaling corresponding to the second signaling is added to 3ms. The feedback signaling corresponding to the second signaling is used to indicate that the terminal device has received the second signaling. For example, the effective time of the second signaling is the time when the last time-domain unit of the PUSCH or PUCCH carrying the PDSCH feedback is added to 3ms. The PUSCH or PUCCH carries the feedback signaling corresponding to the second signaling. For example, the effective time of the second signaling is the time-domain symbol when the last time-domain symbol of the PUSCH or PUCCH carrying the PDSCH feedback is added to 3ms.

[0517] 6. The time at which the first time domain unit of the first reference signal resource associated with the first reported configuration is located after the second signaling takes effect. For example, the first time domain symbol of the first reference signal resource associated with the first reported configuration after the second signaling takes effect.

[0518] The effectiveness of the second signaling can be understood as the time when the second signaling takes effect. Please refer to the aforementioned introduction regarding the effective time of the second signaling.

[0519] 7. The time at which the terminal device receives the first configuration information, which is used to indicate the first reported configuration. For example, as shown in Figure 16, the start time of CPU occupancy is the time at which the terminal device receives the first configuration information.

[0520] For example, the reception time of the first configuration information is the first time domain symbol or the last time domain symbol of the PDCCH carrying the first configuration information; or it is the first time domain symbol after the PDCCH carrying the first configuration information.

[0521] 8. The effective time of the first configuration information.

[0522] In one possible implementation, the effective time of the first configuration information is the time when the terminal device receives the first configuration information plus a duration of X. For example, the effective time of the first configuration information is the time when the last time-domain element of the PDCCH carrying the first configuration information is added to a duration of X. As shown in Figure 17, the effective time of the first configuration information is the time-domain symbol where the last time-domain symbol of the PDCCH carrying the first configuration information is added to a duration of X.

[0523] In another possible implementation, the effective time of the first configuration information is the time when the terminal device sends the feedback signaling corresponding to the first configuration information plus a duration of X. For example, the effective time of the first configuration information is the time when the last time domain unit of the PUCCH or PUSCH carrying the feedback signaling corresponding to the first configuration information is added to the duration of X. For example, the effective time of the first configuration information is the time domain symbol when the last time domain symbol of the PUCCH or PUSCH carrying the feedback signaling corresponding to the first configuration information is added to the duration of X.

[0524] Optionally, X is a positive integer. For example, X = 3ms, 4ms, or 5ms, etc., which is not limited in this application.

[0525] 9. The time at which the first time-domain element of the first reference signal resource after the effective time of the first configuration information is located. Please refer to the aforementioned introduction regarding the effective time of the first configuration information; it will not be repeated here. For example, the first time-domain symbol of the first reference signal resource after the effective time of the first configuration information.

[0526] This implementation method limits some possible implementations of the third time step. This helps to reasonably define the start time of CPU usage and avoids wasting CPU time on terminal devices.

[0527] The following describes some possible implementations of the fourth timeframe. Optionally, the fourth timeframe may include any of the following:

[0528] 1. The time at which the last time domain unit occupied by the last reference signal resource in each of the one or more reference signal resource periods associated with the first reported configuration is located, prior to the receipt of the first signaling. Alternatively, the time at which the last time domain unit occupied by the last reference signal resource in one or more reference signal resource periods associated with the first reported configuration is located, prior to the receipt of the first signaling.

[0529] For example, the fourth moment is: the last time domain symbol or the last time slot occupied by the last reference signal resource in each reference signal resource cycle before receiving the first signaling, within the multiple reference signal resource cycles associated with the first reported configuration.

[0530] In this implementation, the CPU usage time includes P time periods. As shown in Figure 12A, the reference signal resources associated with the first reported configuration before cell handover signaling include reference signal resource 1, reference signal resource 2, and reference signal resource 3. Therefore, the P time periods include time period 1, time period 2, and time period 3. The start time of time period 1 is the last time-domain symbol of reference signal resource 3 in the first cycle. The start time of time period 2 is the last time-domain symbol of reference signal resource 3 in the second cycle. The start time of time period 3 is the last time-domain symbol of reference signal resource 3 in the third cycle.

[0531] Optionally, the time of the last time domain unit occupied by the last reference signal resource in the reference signal resource period where the first reported configuration associated reference signal resource is located, after the first reported configuration associated reference signal resource takes effect and before the first signaling is received.

[0532] 2. The time at which the last time domain unit occupied by the last reference signal resource in each of the multiple reference signal resource periods associated with the first reported configuration is added to M time domain units, where M is an integer greater than or equal to 1, within each reference signal resource period before receiving the first signaling. Alternatively, the time at which the last time domain unit occupied by the last reference signal resource in one or more reference signal resource periods before receiving the first signaling is added to M time domain units, within the multiple reference signal resource periods associated with the first reported configuration.

[0533] For example, the fourth moment is: the time domain symbol occupied by the last time domain symbol of the last reference signal resource in each reference signal resource period before receiving the first signaling, which is located in the multiple reference signal resource periods associated with the first reported configuration, plus M time domain symbols.

[0534] Optionally, the value of M is determined by at least one of the following: communication protocol, network device configuration or indication, and terminal capabilities.

[0535] Optional, M = Z3'.

[0536] 3. The time of the last time domain unit occupied by the last reference signal resource before receiving the first signaling in the first reported configuration associated reference signal resource.

[0537] For example, in the reference signal resources associated with the first reported configuration, the last time domain symbol or the last time slot occupied by the last reference signal resource before receiving the first signaling.

[0538] 4. The time at which the last time domain unit occupied by the last reference signal resource before receiving the first signaling, plus M time domain units, is located in the reference signal resource associated with the first reported configuration.

[0539] For example, in the reference signal resources associated with the first reported configuration, the last time domain symbol occupied by the last reference signal resource before receiving the first signaling, plus M time domain symbols, is the time domain symbol.

[0540] For example, in the reference signal resources associated with the first reported configuration, the time slot is the last time slot occupied by the last reference signal resource before receiving the first signaling, plus M time slots.

[0541] 5. Among the reference signal resources associated with the first reported configuration, the time at which the last time domain unit occupied by the last reference signal resource of the CSI reference resource is located before receiving the first signaling.

[0542] For example, in the reference signal resources associated with the first reported configuration, the last time domain symbol or the last time slot occupied by the last reference signal resource before receiving the first signaling and no later than the last CSI reference resource.

[0543] 6. The time at which the last time domain unit occupied by the last reference signal resource in the first reported configuration associated with the reference signal resource is located before receiving the first signaling and no later than the time after M time domain units.

[0544] For example, in the reference signal resources associated with the first reported configuration, the last time domain symbol occupied by the last reference signal resource before receiving the first signaling and no later than the CSI reference resource, plus M time domain symbols, is the time domain symbol.

[0545] For example, in the reference signal resources associated with the first reported configuration, the time slot is the last time slot occupied by the last reference signal resource before receiving the first signaling and no later than the last CSI reference resource, plus M time slots.

[0546] 7. The time when the terminal device receives the first signaling. For example, as shown in Figure 13, the end time of CPU occupancy (i.e., the fourth time) is the time when the terminal device receives the cell handover signaling.

[0547] For example, the fourth time point is the first or last time domain symbol of the PDSCH carrying the first signaling.

[0548] 8. The timing of sending the feedback signaling corresponding to the first signaling sent by the terminal device.

[0549] For example, the fourth time point is the time when the terminal device sends the PUSCH or PUCCH corresponding to the PDSCH carrying the first signaling, wherein the PUSCH is a PUSCH carrying HARQ-ACK and the PUCCH is a PUCCH carrying HARQ-ACK. Alternatively, the fourth time point is the time when the terminal device sends the first time domain symbol or the last time domain symbol corresponding to the PUSCH or PUCCH carrying the first signaling.

[0550] 9. The time when the terminal device sends the feedback signal corresponding to the first signaling is after the second duration, which is a preset duration.

[0551] For example, as shown in Figure 15, the end time of CPU usage (i.e., the fourth moment) is the time 3ms after the terminal device sends the ACK corresponding to the first signaling.

[0552] For example, the fourth time interval is the time domain symbol 3ms after the terminal device sends the first time domain symbol of the uplink channel (e.g., PUSCH or PUCCH) carrying the feedback signaling corresponding to the first signaling. Alternatively, the fourth time interval is the time domain symbol 3ms after the terminal device sends the last time domain symbol of the uplink channel carrying the feedback signaling corresponding to the first signaling.

[0553] It should be noted that the time when the feedback signaling corresponding to the first signaling sent by the terminal device is after the second duration can also be called the effective time of the first signaling.

[0554] In this implementation, optionally, the measurement report in step 1003 above does not include the measurement results of the target cell, or the first reporting configuration does not have reference signal resources associated with the target cell.

[0555] 10. The time at which the terminal device sends the feedback signaling corresponding to the first signaling is after the second and third durations have elapsed. The third duration is the duration of the cell handover interruption. In other words, the time at which the terminal device sends the feedback signaling corresponding to the first signaling is after the third duration has elapsed.

[0556] This implementation method has been introduced in the previous text, and you can refer to the relevant introduction in the previous text for details. It will not be repeated here.

[0557] 11. The time of the last time domain unit occupied by the uplink resources carrying the measurement report.

[0558] For example, the fourth time point is the last time domain symbol or the last time slot occupied by the uplink resources carrying the measurement report. This implementation method has been introduced earlier, and you can refer to the relevant introduction in the previous text for details, so it will not be repeated here.

[0559] In this implementation, optionally, the measurement report includes the measurement results of the target cell, or the first report may include the reference signal resources of the target cell associated with the configuration.

[0560] 12. The moment when the target cell handover is completed. Please refer to the previous introduction for the information on the moment when the target cell handover is completed; it will not be repeated here.

[0561] The above limits some possible implementation methods for the fourth time step. This helps to reasonably define the end time of CPU usage and avoids wasting CPU time on terminal devices.

[0562] Based on the above implementation methods for the start and end times of CPU usage time, some possible combinations are given below. The following combinations are illustrated using the example where both the fifth and sixth durations are 0.

[0563] Combination Method 1: CPU occupancy time is defined as the time between the moment when the first time domain unit occupied by the first reference signal resource in each reference signal resource cycle before receiving the first signaling, and the moment when the last time domain unit occupied by the last reference signal resource in that cycle is located within one or more reference signal resource cycles associated with the first reported configuration. For example, as shown in Figure 12A, the CPU occupancy time includes time period 1, time period 2, and time period 3. Time period 1 is the time between the first time domain symbol of reference signal resource 1 and the last time domain symbol of reference signal resource 3 in the first cycle. Time period 2 is the time between the first time domain symbol of reference signal resource 1 and the last time domain symbol of reference signal resource 3 in the second cycle. Time period 3 is the time between the first time domain symbol of reference signal resource 1 and the last time domain symbol of reference signal resource 3 in the third cycle.

[0564] Combination Method Two: The CPU occupancy time is defined as follows: within one or more reference signal resource cycles associated with the first reported configuration, the time between the moment when the first time domain unit occupied by the first reference signal resource in each reference signal resource cycle before receiving the first signaling, and the moment when the last time domain unit occupied by the last reference signal resource in that cycle, plus M time domain units, is located. For example, as shown in Figure 12B, the CPU occupancy time includes time period 1, time period 2, and time period 3. Time period 1 is the time between the first time domain symbol of reference signal resource 1 in the first cycle and the moment when the last time domain symbol of reference signal resource 3, plus M time domain symbols, is located. Time period 2 is the time between the first time domain symbol of reference signal resource 1 in the second cycle and the moment when the last time domain symbol of reference signal resource 3, plus M time domain symbols, is located. Time period 3 is the time between the first time domain symbol of reference signal resource 1 in the third cycle and the moment when the last time domain symbol of reference signal resource 3, plus M time domain symbols, is located.

[0565] Please refer to the aforementioned explanations regarding the possible values ​​of M; they will not be repeated here.

[0566] Combination Method 3: The CPU usage time is the time between the moment when the first time domain unit occupied by the first reference signal resource in the first reported configuration associated reference signal resource is located, and the moment when the terminal device receives the first signaling. For example, as shown in Figure 13, reference signal resource 1 is the first reference signal resource in the first reported configuration associated reference signal resource. The CPU usage time is the time between the moment when the first time domain symbol occupied by reference signal resource 1 is located, and the moment when the terminal device receives the cell handover signaling.

[0567] Combination Method Four: The CPU occupancy time is the time between the moment when the first time domain unit occupied by the first reference signal resource in the first reported configuration associated reference signal resource is located, and the moment when the first signaling takes effect. For example, as shown in Figure 13, reference signal resource 1 is the first reference signal resource in the first reported configuration associated reference signal resource. The CPU occupancy time is the time between the moment when reference signal resource 1 occupies the first time domain symbol, and the moment when the terminal device sends the ACK corresponding to the cell handover signaling, 3ms later. That is, the moment when the first signaling takes effect is the moment when the terminal device sends the ACK corresponding to the cell handover signaling, 3ms later.

[0568] Combination Method 5: CPU usage time is the time between the moment the terminal device receives the second signaling and the moment the first signaling takes effect. Please refer to the previous section for the information on the moment the first signaling takes effect. For example, as shown in Figure 14, the second signaling is an activation signaling. The CPU usage time is the time between the last time-domain symbol of the PDSCH carrying the activation signaling and the time-domain symbol where 3ms has elapsed since the terminal device sent the ACK corresponding to the cell handover signaling.

[0569] Combination Method Six: CPU usage time is the time between the effective time of the second signaling and the effective time of the first signaling. Please refer to the previous sections for the effective times of the first and second signaling. For example, as shown in Figure 15, the second signaling is an activation signaling, and its effective time is the last time-domain symbol in the PUSCH or PUCCH carrying the feedback signaling corresponding to the second signaling. The effective time of the first signaling is the time-domain symbol 3ms after the terminal device sends the ACK corresponding to the cell handover signaling. CPU usage time is the time between the last time-domain symbol in the PUSCH or PUCCH carrying the feedback signaling corresponding to the second signaling and the time-domain symbol 3ms after the terminal device sends the ACK corresponding to the cell handover signaling.

[0570] Combination Method Seven: The CPU usage time is the time between the moment when the first time domain element of the first reference signal resource associated with the first reported configuration takes effect after the second signaling takes effect, and the moment when the first signaling takes effect. Alternatively, it can be the time between the moment when the first time domain element of the first reference signal resource associated with the first reported configuration takes effect after the moment when the second signaling takes effect, and the moment when the first signaling takes effect. Please refer to the previous sections for the information on the moment when the first and second signaling take effect; they will not be repeated here. For example, as shown in Figure 15, the second signaling is an activation signaling, and the moment when the second signaling takes effect is the last time domain symbol in the PUSCH or PUCCH carrying the feedback signaling corresponding to the second signaling. The first reference signal resource after the moment when the second signaling takes effect is reference signal resource 1. The moment when the first signaling takes effect is the time domain symbol 3ms after the time when the terminal device sends the ACK corresponding to the cell handover signaling. Therefore, the CPU usage time is the time between the first time domain symbol of reference signal resource 1 and the time domain symbol 3ms after the time when the terminal device sends the ACK corresponding to the cell handover signaling.

[0571] Optionally, the above combination methods five to seven are applicable to the case where the reference signal resource associated with the first reported configuration is a semi-persistent reference signal resource.

[0572] Combination Method 8: CPU usage time is the time between the moment the terminal device receives the first configuration information and the moment the first signaling takes effect. Please refer to the previous section for the information on the moment the first signaling takes effect. For example, as shown in Figure 16, the moment the first configuration information is received is the first time-domain symbol of the PDCCH carrying that first configuration information. The moment the first signaling takes effect is the time-domain symbol 3ms after the moment the terminal device sends the ACK corresponding to the cell handover signaling. Therefore, the CPU usage time is the time between the first time-domain symbol of the PDCCH carrying the first configuration information and the time-domain symbol 3ms after the moment the terminal device sends the ACK corresponding to the cell handover signaling.

[0573] Combination Method Nine: CPU usage time is the time between the effective time of the first configuration information and the effective time of the first signaling. Please refer to the previous section for the effective time of the first signaling. For example, as shown in Figure 17, the effective time of the first configuration information is the time symbol in the time domain after 3ms, which is the last time domain symbol of the PDCCH carrying the first configuration information. The effective time of the first signaling is the time symbol in the time domain after 3ms, which is the time when the terminal device sends the ACK corresponding to the cell handover signaling. The CPU usage time is the time between the last time domain symbol of the PDCCH carrying the first configuration information plus the time symbol in the time domain after 3ms, and the time symbol in the time domain after 3ms, which is the time when the terminal device sends the ACK corresponding to the cell handover signaling.

[0574] Combination Method 10: CPU usage time is the time between the moment the terminal device receives the second signaling and the moment it receives the first signaling. For example, as shown in Figure 15, the first signaling is cell handover signaling, and the second signaling is activation signaling. The moment the second signaling is received is the last time-domain symbol in the PDSCH or PDCCH carrying the activation signaling. The moment the first signaling is received is the last time-domain symbol in the PDSCH or PDCCH carrying the cell handover signaling. Therefore, the CPU usage time is the time between the last time-domain symbol in the PDSCH or PDCCH carrying the activation signaling and the last time-domain symbol in the PDSCH or PDCCH carrying the cell handover signaling.

[0575] Combination Method 11: CPU usage time is the time between the effective time of the second signaling and the time when the terminal device receives the first signaling. Please refer to the previous section for the effective time of the second signaling. For example, as shown in Figure 15, the first signaling is a cell handover signaling, and the second signaling is an activation signaling. The effective time of the second signaling is the last time-domain symbol in the PUSCH or PUCCH carrying the feedback signaling corresponding to the activation signaling. The receiving time of the first signaling is the last time-domain symbol in the PDSCH or PDCCH carrying the cell handover signaling. Therefore, the CPU usage time is the time between the last time-domain symbol in the PUSCH or PUCCH carrying the feedback signaling corresponding to the activation signaling and the last time-domain symbol in the PDSCH or PDCCH carrying the cell handover signaling.

[0576] Optionally, the above combination method ten and combination method eleven are applicable to the case where the reference signal resource associated with the first reported configuration is a semi-persistent reference signal resource.

[0577] Combination Method Twelve: CPU usage time is the time between the moment the terminal device receives the first configuration information and the moment the terminal device receives the first signaling. For example, as shown in Figure 16, the first signaling is cell handover signaling, and the moment the first configuration information is received is the first time-domain symbol of the PDCCH carrying the first configuration information. The moment the first signaling is received is the last time-domain symbol in the PDSCH or PDCCH carrying the cell handover signaling. Therefore, the CPU usage time is the time between the first time-domain symbol of the PDCCH carrying the first configuration information and the last time-domain symbol in the PDSCH or PDCCH carrying the cell handover signaling.

[0578] Combination Method Thirteen: The CPU usage time is the time between the effective time of the first configuration information and the time when the terminal device receives the first signaling. Please refer to the previous section for the effective time of the first configuration information. For example, as shown in Figure 17, the first signaling is cell handover signaling. The effective time of the first configuration information is the time symbol containing the last time domain symbol of the PDCCH carrying the first configuration information plus Xms. The receiving time of the first signaling is the last time domain symbol in the PDSCH or PDCCH carrying the cell handover signaling. Therefore, the CPU usage time is the time between the last time domain symbol of the PDCCH carrying the first configuration information plus Xms and the last time domain symbol in the PDSCH or PDCCH carrying the cell handover signaling.

[0579] Optionally, the above combination methods twelve and thirteen are applicable to the case where the reference signal resource associated with the first reported configuration is a periodic reference signal resource.

[0580] Combination Method Fourteen: CPU occupancy time is the time between the time of the first time domain unit of the first reference signal resource after the effective time of the first configuration information and the effective time of the first signaling. Please refer to the previous section for the effective time of the first signaling. For example, CPU occupancy time is the time between the first time domain symbol of the first reference signal resource after the effective time of the first configuration information and the time domain symbol where the first signaling takes effect. For example, as shown in Figure 17, the effective time of the first configuration information is the time domain symbol containing the last time domain symbol of the PDCCH carrying the first configuration information plus Xms. The first reference signal resource after the effective time of the first configuration information is reference signal resource 1. The first signaling is cell handover signaling, and the time domain symbol where the first signaling takes effect is the time domain symbol containing 3ms after the time when the terminal device sends the ACK corresponding to the cell handover signaling. CPU occupancy time is the time between the last time domain symbol of the PDCCH carrying the first configuration information plus Xms, the first time domain symbol of reference signal resource 1, and the time domain symbol containing 3ms after the time when the terminal device sends the ACK corresponding to the cell handover signaling.

[0581] Optionally, any of the aforementioned combination methods one to fourteen is applicable when the measurement report does not include the measurement results of the target cell, or when the first reporting configuration does not have reference signal resources associated with the target cell.

[0582] Optionally, in any of the above combinations one through fourteen, the end time of CPU occupancy can be replaced with the last time-domain symbol of the reporting resource carrying the measurement report. Optionally, when the measurement report includes the measurement results of the target cell, in any of the above combinations one through fourteen, the end time of CPU occupancy can be replaced with the last time-domain symbol of the reporting resource carrying the measurement report.

[0583] Optionally, any of the aforementioned combinations one to fourteen is applicable to measurement reports that include measurement results of the target cell, or to the first reporting configuration associated with the reference signal resources of the target cell.

[0584] Therefore, we believe that the start of CPU usage time for CSI reports depends on the temporal attributes of the CSI-RS resource associated with the CSI report and whether the UE can measure CSI before CSC. If the UE can measure CSI before CSC and / or the network configuration measures before CSC, for semi-persistent CSI-RS resources, CPU usage time can start from the first temporal symbol 3ms after the last temporal symbol occupied by the HARQ-ACK corresponding to the MAC CE used to activate semi-persistent CSI-RS. For periodic CSI-RS resources, CPU usage time can start from the first temporal symbol of the earliest CSI-RS resource after the RRC configuration used to configure the periodic CSI resource.

[0585] In one possible implementation, for CSI measurements prior to CSC, the start time of CPU occupancy can be the first time domain symbol 3ms after the last time domain symbol occupied by the HARQ-ACK corresponding to the MAC CE used to activate the semi-persistent CSI-RS associated with CSI reporting.

[0586] Another possible implementation is that, for CSI measurements prior to CSC, the start time of CPU usage can be the first time-domain symbol of the earliest CSI-RS resource after the RRC configuration used to configure the periodic CSI resource associated with the CSI report.

[0587] For CSI measurements prior to CSC, the end time of CPU occupancy depends on whether the CSI report is associated with CSI-RS resources from the target cell. If the CSI report is associated with CSI resources from the target cell, the end time of CPU occupancy can be the last time-domain symbol of the uplink resource carrying the CSI report. If the CSI report is associated with CSI resources from a non-target cell, i.e., the CSI report does not include CSI measurement results from the target cell, the end time of CPU occupancy can be the last time-domain symbol of the HARQ-ACK occupancy corresponding to the uplink resource carrying the LTM CSC MAC CE. The LTM CSC MAC CE is the MAC CE carrying the CSC.

[0588] For cases where the UE measures CSI after CSC, the CPU usage time is: from the first time domain symbol of the earliest CSI resource after 3ms, which is the last time domain symbol occupied by the HARQ-ACK corresponding to the LTM CSC MAC CE in the CSC resource associated with the CSI report, to the last time domain symbol of the uplink resource carrying the CSI report.

[0589] Optionally, the number of CPUs includes any of the following:

[0590] 1. The number of reference signal resources associated with the first reported configuration. For example, if the first reported configuration is associated with only one reference signal resource, then the number of CPUs is 1.

[0591] 2. The number of activated reference signal resources among the reference signal resources associated with the first reported configuration. For example, if the first reported configuration is associated with one or more semi-persistent reference signal resources, then the number of CPUs is the number of activated reference signal resources. This implementation is applicable to the case where the first reported configuration is associated with semi-persistent reference signal resources.

[0592] 3. The first report should specify the number of effective reference signal resources among the associated reference signal resources. Please refer to the aforementioned introduction regarding the activation method of reference signal resources; it will not be repeated here.

[0593] 4. The number of reference signal resources of the target cell associated with the first reported configuration. The target cell is one of one or more candidate cells, and the target cell is the cell indicated by the first signaling, which instructs the terminal device to hand over to the target cell.

[0594] Optionally, this implementation method is applicable to terminal devices using CSI acquisition method one to acquire CSI of candidate cells. For example, the first reporting configuration associates reference signal resources of one or more candidate cells. The one or more candidate cells include the target cell, and the number of CPUs is the number of reference signal resources of the target cell associated with the first reporting configuration.

[0595] 5. The maximum number of CPUs supported by the terminal device, or the maximum number of CPUs supported by the terminal device for simultaneous CSI calculation.

[0596] Optionally, this implementation method is applicable to terminal devices using CSI acquisition method one to acquire the CSI of candidate cells.

[0597] 6. The maximum number of CPUs supported by the terminal device for acquiring the CSI of candidate cells.

[0598] Optionally, this implementation method is applicable to terminal devices using CSI acquisition method one to acquire the CSI of candidate cells.

[0599] 7. The communication protocol specifies the number of CPUs L corresponding to the reporting configuration used for candidate cell CSI acquisition. L is a positive integer. For example, L = 1. The number of CPUs L corresponding to the reporting configuration used for candidate cell CSI acquisition can be understood as: the number of CPUs required for the terminal device to measure the measurement resources associated with the reporting configuration to obtain a CSI report, or the number of CPUs required for the terminal device to measure the measurement resources associated with the reporting configuration to obtain and report a CSI report.

[0600] The above illustrates some possible implementations of the number of CPUs, thus allowing for a reasonable determination of the number of CPUs and avoiding CPU waste in terminal devices.

[0601] In the above technical solution, the terminal device measures one or more reference signal resources associated with the first reporting configuration and obtains a measurement report. These one or more reference signal resources include reference signal resources of one or more candidate cells of the terminal device. Then, the terminal device sends the measurement report. This measurement report corresponds to first CPU information, which includes CPU usage time and / or the number of CPUs. This enables the terminal device to measure and report the reference signals of one or more candidate cells. It also enables the network device to obtain the channel state information of the one or more candidate cells. Furthermore, the measurement report corresponds to first CPU information, which includes CPU usage time and / or the number of CPUs. This specifies the number of CPUs and CPU usage time required for the terminal device to obtain and / or report the measurement report, which helps avoid CPU waste by the terminal device.
