Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a cell measurement method and apparatus. Background Technology

[0002] Mobility measurement is the foundation of mobility management. In a mobile communication system, the network sends measurement configurations to terminal devices. The terminal devices measure the cell according to the measurement configurations and determine whether a measurement report needs to be sent to the network. If so, the terminal devices send a measurement report to the network, which then makes mobility decisions and / or manages carriers accordingly.

[0003] In existing technologies, terminal devices measure the detectable cells based on measurement configurations. Due to the large number of measurement objects and measurements, the energy consumption of terminal devices is relatively high. Summary of the Invention

[0004] This application provides a cell measurement method and apparatus that can flexibly control the number of measurement objects and the number of measurements of the terminal device, which is beneficial to reducing the energy consumption of the terminal device.

[0005] In a first aspect, embodiments of this application provide a cell measurement method, which may include: receiving first indication information from a network device, the first indication information indicating that at least one candidate cell needs to be measured; sending a first reporting message to the network device, the first reporting message indicating the measurement result of the at least one candidate cell; and receiving second indication information from the network device, the second indication information indicating that a first number of measurements of a first candidate cell is performed within a first time period, the at least one candidate cell including the first candidate cell.

[0006] The cell measurement method provided in this application embodiment allows the terminal device to measure and report the measurement results of at least one candidate cell based on the first indication information of the network device, and to perform the first number measurement of the first candidate cell within a first time period based on the second indication information of the network device. This method can flexibly control the number of measurement objects and the number of measurements of the terminal device, which is beneficial to reducing the energy consumption of the terminal device.

[0007] It should be noted that the serving cell is the cell currently providing service to this terminal device, i.e., the source cell.

[0008] In one possible implementation, the first indication information may be a Radio Resource Control (RRC) message, or may be carried in an RRC message.

[0009] Optionally, the first indication information may be a Media Access Control Element (i.e., MAC CE) or Downlink Control Information (i.e., DCI).

[0010] In one possible implementation, the first indication information may include at least one measurement identifier, which corresponds one-to-one with the at least one candidate cell, and each measurement identifier is used to indicate whether it is necessary to measure the candidate cell corresponding to each measurement identifier.

[0011] Optionally, before sending the reporting message 2 to the network device, the terminal device performs a measurement on the at least one candidate cell based on the first indication information to obtain the measurement result of the at least one candidate cell.

[0012] In one possible implementation, the cell measurement described in this application embodiment may include measuring the quality of the cell.

[0013] Optionally, before sending the first reporting message 2 to the network device, the method may further include: the terminal device performing a measurement on the at least one candidate cell based on the first indication information to obtain the measurement result of the at least one candidate cell.

[0014] For example, the measurement result may include at least one of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), or signal-to-interference-plus-noise ratio (SINR).

[0015] In one possible implementation, the second instruction information can be MAC CE or DCI.

[0016] In one possible implementation, the second indication information includes first count information and time information, wherein the first count information is used to indicate the first count and the time information is used to indicate the first time period.

[0017] In one possible implementation, the second indication information may also include at least one measurement identifier.

[0018] In one possible implementation, the at least one candidate cell further includes a second candidate cell, and the second indication information is also used to indicate that a second number is measured for the second candidate cell during the first time period, the first number being greater than the second number.

[0019] In one possible implementation, the second indication information further includes second number information, which is used to indicate the second number.

[0020] In one possible implementation, the method further includes: measuring the first number of the first candidate cell within the first time period based on the second indication information.

[0021] Optionally, the method 200 may further include: the terminal device measuring the second number of the second candidate cell within the first time period based on the indication information 2.

[0022] Optionally, the second number can be greater than or equal to 0.

[0023] In one possible implementation, if the number of at least one candidate cells is greater than 1, and the second count is equal to 0, it can be understood that during the first time period, the terminal device only needs to perform the first count measurement on the candidate cells with good quality among the at least one candidate cells, without needing to measure the candidate cells with poor quality among the at least one candidate cells. This reduces the number of measurement objects, thereby reducing the energy consumption of the terminal device.

[0024] Optionally, in this embodiment of the application, the terminal device performs a high number of measurements on the candidate cells with good quality among the at least one candidate cells during the first time period, or it can be replaced by the terminal device performing a first cycle of measurements on the candidate cells with good quality among the at least one candidate cells.

[0025] In another possible implementation, when the number of at least one candidate cells is greater than 1, if the second number is greater than 0 and the first number is greater than the second number, it can be understood that within the first time period, the terminal device performs a high number of measurements on the candidate cells with good quality among the at least one candidate cells, and performs a low number of measurements on the candidate cells with poor quality among the at least one candidate cells. This reduces the total number of cell measurements, thereby reducing the power consumption of the terminal device.

[0026] Optionally, in the embodiments of this application, during the first time period, the terminal device performs a high number of measurements on the candidate cells with good quality among the at least one candidate cells, which can be replaced by the terminal device performing short-cycle measurements (i.e., high-frequency measurements) on the candidate cells with good quality among the at least one candidate cells; or, the terminal device performs a low number of measurements on the candidate cells with poor quality among the at least one candidate cells, which can be replaced by the terminal device performing long-cycle measurements (i.e., low-frequency measurements) on the candidate cells with poor quality among the at least one candidate cells.

[0027] Optionally, before the terminal device performs the first number measurement of the first candidate cell within the first time period, the terminal device may determine in various ways whether to initiate the measurement GAP.

[0028] In one possible implementation, before the first measurement of the first candidate cell is performed based on the second indication information within the first time period, the method further includes: determining that the first candidate cell and the current serving cell belong to inter-frequency cells or inter-system cells; and initiating a measurement gap.

[0029] In other words, the terminal device can determine on its own whether to initiate a measurement gap. This reduces the interaction between network devices and terminal devices, thereby reducing the power consumption of the terminal device.

[0030] In one possible implementation, the second indication information is further used to indicate the initiation of a measurement GAP. Before the first number measurement of the first candidate cell is performed based on the second indication information within the first time period, the method further includes: initiating a measurement GAP based on the second indication information.

[0031] In other words, the terminal device can initiate a measurement gap based on network instructions. This reduces the computational load on the terminal device, thereby reducing its energy consumption.

[0032] Secondly, embodiments of this application provide a cell measurement method, which may include: sending a first indication message to a terminal device, the first indication message indicating that at least one candidate cell needs to be measured; receiving a first reporting message from the terminal device, the first reporting message indicating the measurement result of the at least one candidate cell; and based on the first reporting message, sending a second indication message to the terminal device, the second indication message indicating that a first number of measurements of a first candidate cell is performed within a first time period, the at least one candidate cell including the first candidate cell, and the quality of the first candidate cell in the measurement result of the at least one candidate cell being greater than or equal to a first threshold value.

[0033] Using the cell measurement method provided in this application embodiment, the network device instructs the terminal device to measure and report the measurement results of at least one candidate cell through a first instruction message; based on the first reporting message sent by the terminal device, the network device sends a second instruction message to the terminal device, instructing the terminal device to perform the first number of measurements on the first candidate cell within a first time period. This allows for flexible control over the number of measurement objects and the number of measurements by the terminal device, which is beneficial for reducing the energy consumption of the terminal device.

[0034] In one possible implementation, the second indication information includes first count information and time information, wherein the first count information is used to indicate the first count and the time information is used to indicate the first time period.

[0035] In one possible implementation, the at least one candidate cell further includes a second candidate cell, and the second indication information is also used to indicate that a second number of measurements of the second candidate cell is performed during the first time period, the first number being greater than the second number, and the quality of the second candidate cell in the measurement results of the at least one candidate cell being less than the first threshold value.

[0036] In one possible implementation, the second indication information further includes second number information, which is used to indicate the second number.

[0037] In one possible implementation, the second indication information is either the Media Access Control (MAC) control element (CE) or the Downlink Control Information (DCI).

[0038] In one possible implementation, the second instruction information is also used to instruct the initiation of measurement GAP.

[0039] It should be noted that for the parts not explained in detail in the second aspect, please refer to the corresponding parts in the first aspect. To avoid repetition, they will not be repeated here.

[0040] Thirdly, embodiments of this application provide a cell measurement method, which may include: measuring at least one candidate cell; and, based on the measurement results of the at least one candidate cell, performing a first-time measurement on a first candidate cell within a first time period, wherein the at least one candidate cell includes the first candidate cell, and the quality of the first candidate cell in the measurement results of the at least one candidate cell is greater than or equal to a first threshold value.

[0041] Using the cell measurement method provided in this application embodiment, the terminal device can perform the first number measurement of the first candidate cell within a first time period based on the measurement results of at least one candidate cell. This allows for flexible control of the number of measurement objects and the number of measurements by the terminal device, which is beneficial for reducing the energy consumption of the terminal device.

[0042] In one possible implementation, the terminal device can perform a measurement on the at least one candidate cell.

[0043] For example, the measurement result may include at least one of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), or signal-to-interference-plus-noise ratio (SINR).

[0044] In one possible implementation, before performing the first number measurement of the first candidate cell within a first time period based on the measurement results of the at least one candidate cell, the method further includes: sending a second reporting message to the network device, the second reporting message indicating that the first candidate cell needs to be measured.

[0045] Optionally, before performing the first measurement of the first candidate cell within the first time period based on the measurement results of the at least one candidate cell, the terminal device may also report to the network device that the third candidate cell also needs to be measured.

[0046] Optionally, in the measurement results of the at least one candidate cell, the quality of both the first candidate cell and the third candidate cell is greater than or equal to the first threshold value.

[0047] Optionally, the terminal device can report the need to measure the first candidate cell and the third candidate cell in various ways.

[0048] In one possible implementation, after measuring the at least one candidate cell, the terminal device can report via a reporting message that it needs to measure the first candidate cell and the third candidate cell.

[0049] For example, the second reporting message is also used to indicate that the third candidate cell needs to be measured.

[0050] In another possible implementation, after measuring the quality of the first candidate cell to be greater than or equal to a first threshold value, the terminal device may report the need to measure the first candidate cell through a reporting message, and after measuring the quality of the third candidate cell to be greater than or equal to the first threshold value, it may report the need to measure the third candidate cell through another reporting message.

[0051] For example, when the quality of the first candidate cell among the at least one candidate cells is measured to be greater than or equal to the first threshold, the terminal device sends the second reporting message to the network device; when the quality of the third candidate cell among the at least one candidate cells is measured to be greater than or equal to the first threshold, the terminal device sends a third reporting message to the network device, the third reporting message indicating that the third candidate cell needs to be measured.

[0052] In one possible implementation, the at least one candidate cell further includes a second candidate cell, and the method further includes: based on the measurement results of the at least one candidate cell, performing a second number measurement on the second candidate cell within the first time period, wherein the quality of the second candidate cell in the measurement results of the at least one candidate cell is less than the first threshold value, and the first number is greater than the second number.

[0053] Optionally, the second number can be greater than or equal to 0.

[0054] In one possible implementation, if the number of at least one candidate cells is greater than 1, and the second number is equal to 0, it can be understood that during the first time period, the terminal device only needs to measure the candidate cells with good quality among the at least one candidate cells, and does not need to measure the candidate cells with poor quality among the at least one candidate cells. In this way, the number of measurement objects can be reduced, thereby reducing the energy consumption of the terminal device.

[0055] Optionally, in this embodiment of the application, the terminal device performs a high number of measurements on the candidate cells with good quality among the at least one candidate cells during the first time period, or it can be replaced by the terminal device performing a first cycle of measurements on the candidate cells with good quality among the at least one candidate cells.

[0056] In another possible implementation, when the number of at least one candidate cells is greater than 1, if the second number is greater than 0 and the first number is greater than the second number, it can be understood that within the first time period, the terminal device needs to perform a high number of measurements on the candidate cells with good quality among the at least one candidate cells, and a low number of measurements on the candidate cells with poor quality among the at least one candidate cells. This reduces the total number of cell measurements, thereby reducing the energy consumption of the terminal device.

[0057] Optionally, in the embodiments of this application, during the first time period, the terminal device performs a high number of measurements on the candidate cells with good quality among the at least one candidate cells, which can be replaced by the terminal device performing short-cycle measurements (i.e., high-frequency measurements) on the candidate cells with good quality among the at least one candidate cells; or, the terminal device performs a low number of measurements on the candidate cells with poor quality among the at least one candidate cells, which can be replaced by the terminal device performing long-cycle measurements (i.e., low-frequency measurements) on the candidate cells with poor quality among the at least one candidate cells.

[0058] In one possible implementation, the first time period and / or the first threshold value are pre-configured. This reduces the interaction between network devices and terminal devices, thereby reducing the power consumption of the terminal devices.

[0059] In one possible implementation, before performing the first number measurement on the first candidate cell within a first time period based on the measurement results of the at least one candidate cell, the method further includes: determining that the first candidate cell and the current serving cell belong to inter-frequency cells or inter-system cells; and initiating a measurement gap.

[0060] In other words, the terminal device can determine whether to initiate a measurement gap. This reduces the interaction between network devices and terminal devices, thereby reducing the power consumption of the terminal device.

[0122] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0123] In the embodiments of this application, terms such as "first" and "second" are used to distinguish identical or similar items with substantially the same function and purpose. For example, "first chip" and "second chip" are used only to distinguish different chips and do not limit their order of execution. Those skilled in the art will understand that terms such as "first" and "second" do not limit the quantity or execution order, and that "first" and "second" do not necessarily imply that they are different.

[0124] It should be noted that in the embodiments of this application, the terms "example" or "for example" are used to indicate that they are used as examples, illustrations, or explanations. Any embodiment or design that is described as "example" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design options. Specifically, the use of terms such as "example" or "for example" is intended to present the relevant concepts in a specific manner.

"And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, a--c, bc, or abc, where a, b, and c can be single or multiple.

[0126] To facilitate a clear description of the technical solutions in the embodiments of this application, some terms and technologies involved in the embodiments of this application will be briefly introduced first:

[0127] 1. Cell: A cell is a term used by higher-level developers to describe a resource management, mobility management, or service unit. The coverage area of ​​each network device can be divided into one or more cells, and each cell can correspond to one or more frequency points. In other words, each cell can be considered as an area formed by the coverage of one or more frequency points.

[0128] It should be noted that a cell can be the area covered by the wireless network of a network device. In the embodiments of this application, different cells can correspond to the same or different network devices. For example, the network device belonging to cell #1 and the network device belonging to cell #2 can be different network devices, such as base stations. That is, cell #1 and cell #2 can be managed by different base stations. Or, for another example, the network device managing cell #1 and the network device managing cell #2 can also be different radio frequency processing units of the same base station, such as radio remote units (RRUs). That is, cell #1 and cell #2 can be managed by the same base station, have the same baseband processing unit and intermediate frequency processing unit, but have different video processing units. Or, for yet another example, the network device belonging to cell #1 and the network device belonging to cell #2 can be the same network device, such as a base station. That is, cell #1 and cell #2 can be managed by the same base station. In this case, it can be referred to as cell #1 and cell #2 being co-located. This embodiment of the application does not make any special limitation on this.

[0129] For example, in some possible deployments, a base station may include a central unit (CU) and / or a distributed unit (DU). In such a deployment, cell #1 and cell #2 may be managed by the same CU and the same DU, i.e., sharing both CU and DU; or, cell #1 and cell #2 may be managed by the same CU and different DUs, i.e., sharing both CU and DU; or, cell #1 and cell #2 may also be managed by different CUs and different DUs, i.e., not sharing either CU or DU.

[0130] 2. Reference signal

[0131] In wireless communication systems, a reference signal (RS) is a special signal used for channel measurement and calibration. It is typically transmitted in the communication link at predetermined intervals and in a predetermined manner. The reference signal helps the receiver perform critical functions such as channel estimation, synchronization, and power control, thereby ensuring the accuracy and stability of data transmission.

[0132] Reference signals are used to measure channel state information (CSI), helping the receiver estimate channel characteristics such as path loss and multipath effects. They can also be used for time and frequency synchronization, ensuring that the transmitter and receiver communicate on the same time and frequency; and to measure the strength of received signals for power control, ensuring that signals are transmitted at appropriate power levels. Reference signals are also used for cell selection and handover. User equipment (UE) uses the quality of the reference signal to select the best cell for connection and performs inter-cell handovers during movement. In multi-cell environments, reference signals help coordinate and reduce inter-cell interference, improving overall network performance.

[0133] For example, taking a 5G NR system as an example, common reference signals include: demodulation reference signal (DM-RS), used for downlink and uplink data demodulation and sent during data transmission; phase tracking reference signal (PT-RS), used for phase noise correction, especially in high-frequency bands; synchronization signal and physical broadcast channel block (SS / PBCH Block), including synchronization signal (SS) and physical broadcast channel (PBCH), used for initial synchronization and broadcasting system information; channel state information reference signal (CSI RS), used for downlink channel state information measurement to help with beamforming and multiple-input multiple-output (MIMO) operations; and sounding reference signal (SRS), used for uplink channel measurement.

[0134] 3. Switch

[0135] In wireless communication systems, when a terminal device moves / approaches another cell, a handover is required to ensure uninterrupted communication. In this embodiment, the source cell refers to the cell that provides service to the terminal device before the handover, and the target cell refers to the cell that provides service to the terminal device after the handover. Information about the target cell (such as its physical cell identifier, frequency information, and random access resource information required for handover) can be indicated by a handover message sent by the network device (i.e., the source network device) to the terminal device.

[0136] Handover can be intra-site handover or inter-site handover. Intra-site handover refers to the source cell and target cell belonging to the same network device (such as a base station), where the source cell and target cell can be the same cell or different cells. Inter-site handover refers to the source cell and target cell belonging to different network devices (such as base stations). This application does not limit this.

[0137] For example, the source cell corresponds to the source network device (e.g., the source base station), and the target cell corresponds to the target network device (e.g., the target base station). The source base station and the target base station may be the same or different.

[0138] 4. L1 / L2 triggered mobility (L1 / L2 LTM) switching

[0139] L1 / L2 LTM handover, also known as L1 / L2 handover, refers to the physical layer (L1) and the medium access control (MAC) layer (L2), radio link control (RLC) layer (LLC), packet data convergence protocol (PDCP), and service data adaptation protocol (SDAP) layer (L2).

[0140] For example, during the L1 / L2 switching process, L2 mainly refers to the MAC layer.

[0141] For example, in a base station architecture with CU-DU separation, the L1 / L2 LTM process is as follows: The terminal device sends the L1 measurement results to the base station via physical layer control signaling (carried on the physical uplink control channel (PUCCH)). The base station's physical layer reads the L1 measurement results, and based on the measurement results, the base station sends the handover decision to the terminal device via L1 / L2 signaling. The L1 / L2 signaling can be a message carried on the physical downlink control channel (PDCCH) or a MAC control element (MAC CE).

[0142] 5. LTM Event

[0143] LTM2 Event: The quality of the serving cell and / or reference signal is less than the threshold value of 1;

[0144] LTM3 Event: The quality of the candidate cell and / or reference signal is greater than or equal to the quality of the serving cell;

[0145] LTM4 Event: The quality of the candidate cell and / or reference signal is greater than or equal to the threshold value 2;

[0146] LTM5 Event: The quality of the serving cell and / or reference signal is less than or equal to threshold 3, and the quality of the candidate cell and / or reference signal is greater than or equal to threshold 4.

[0147] 6. Measure GAP

[0148] The measurement gap (GAP) is used when the receiver bandwidth of the terminal equipment is insufficient to simultaneously cover the frequency of both the serving cell and the frequency of the cell under test. In this case, the terminal equipment will measure the cell under test using a certain GAP. When the terminal equipment operates on a single radio frequency, it requires the assistance of the measurement gap to effectively measure different frequencies and systems.

[0149] The technical solutions of this application embodiment can be applied to various communication systems. For example, Global System for Mobile Communications (GSM), Long Term Evolution (LTE) systems, Universal Mobile Telecommunications System (UMTS), 4th Generation (4G) mobile communication systems, 4.5th Generation (4.5G) mobile communication systems, Worldwide Interoperability for Microwave Access (WiMAX) communication systems, 5th Generation (5G) mobile communication systems, or new radio access technology (NR). Furthermore, with the continuous development of communication technology, the technical solutions of this application embodiment can also be used in subsequently evolved communication systems, such as 6th Generation (6G) mobile communication systems, 7th Generation (7G) mobile communication systems, and so on. The technical solutions of this application embodiment can also be applied to Universal Mobile Telecommunications System (UMTS), Code Division Multiple Access (CDMA) systems, Wireless Local Area Networks (WLANs), etc. The technical solutions of this application embodiment can also be applied to vehicle-to-X (V2X), where V2X can include vehicle-to-network (V2N), vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), Long Term Evolution-Vehicle (LTE-V), vehicle-to-everything (V2X), machine-type communication (MTC), Internet of Things (IoT), Long Term Evolution-Machine (LTE-M), machine-to-machine (M2M), etc.

[0150] To facilitate understanding of the embodiments of this application, firstly, in conjunction with Figure 1 The communication system applicable to the embodiments of this application is described in detail.

[0151] Figure 1 A schematic diagram of a communication system 100 applicable to the cell measurement method and apparatus of this application is shown. Figure 1 As shown, the communication system 100 may include at least one network device, such as... Figure 1 The network device 110 shown; the communication system 100 may also include at least one terminal device, such as Figure 1 The terminal device 120 shown is described above. Each network device can provide communication coverage for a specific geographical area and can communicate with terminal devices located within that coverage area (cell).

[0152] Network device 110 can communicate with terminal device 120 via a wireless link.

[0153] For example, terminal device 120 is located within the coverage area of ​​one or more cells (carriers) managed by network device 110. There can be one or more cells providing services to the terminal device. When multiple cells provide services to the terminal device, the terminal device can operate using carrier aggregation (CA), dual connectivity (DC), or cooperative multipoint transmission modes. At least one of the multiple cells can provide at least two sets of parameters (numerology) to simultaneously provide radio resources to the terminal device. For example, the terminal device may simultaneously be located within the coverage area of ​​cells managed by network device #1, network device #2, and network device #3. Network device #1 may be, for example, a macro base station (macro eNB or macro e-NodeB), and network devices #2 and #3 may be, for example, small eNBs or small e-NodeBs.

[0154] Figure 1 An exemplary network device and a terminal device are shown. Optionally, the communication system 100 may include one or more network devices and each network device may include other terminal devices within its coverage area. This application embodiment does not limit this.

[0155] The above communication devices, such as Figure 1The network device 110 or terminal device 120 can be configured with multiple antennas. These multiple antennas may include at least one transmitting antenna for transmitting signals and at least one receiving antenna for receiving signals. Additionally, each communication device also includes a transmitter chain and a receiver chain, which, as will be understood by those skilled in the art, may each include multiple components (e.g., processors, modulators, multiplexers, mediators, demultiplexers, or antennas) related to signal transmission and reception. Therefore, the network device and the terminal device can communicate via antenna technology.

[0156] Optionally, the communication system 100 may also include other network entities such as a network controller, a mobility management entity, or a core network element; however, the embodiments of this application are not limited thereto.

[0157] In this application embodiment, the terminal device may also be referred to as UE, terminal, access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, user agent, or user equipment, and can be applied to 4G, 5G, or even 6G systems. The terminal device can provide voice and / or data connectivity to the user. Terminal devices can be joint devices that transmit and receive digital signals over ordinary telephone lines, handheld devices with wireless connectivity, in-vehicle devices, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), mobile phones, tablets, laptops, PDAs, computers with wireless transceiver capabilities, mobile internet devices (MIDs), wearable devices, head-mounted displays (HMDs), virtual reality (VR) devices (such as VR glasses), augmented reality (AR) devices (such as AR glasses), mixed reality (MR) devices, wireless terminals in industrial control, wireless terminals in Internet of Things (IoT) systems, processing devices connected to wireless modems, tactile terminal devices, in-vehicle devices, wireless terminals in self-driving vehicles, and remote medical devices. Wireless terminals in medical applications, smart grids, transportation safety, smart cities, smart homes, and roadside units (RSUs) of the aforementioned wireless terminal types are not limited to these in this application.

[0158] In this embodiment, the network device can be an access network device, which is a radio access network (RAN) node (or device) that connects the terminal device to the wireless network. Network devices include, but are not limited to: base station (BS), radio network controller (RNC), 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), wireless fidelity (Wi-Fi) access point (AP), wireless relay node, wireless backhaul node, and transmission and reception point (TRP; or transmission point, TP). A base station is a device deployed in the radio access network that can provide wireless communication functions; it can also be called a base station device, such as an evolved Node B (eNB or e-NodeB) in an LTE system, a Node B (NB), a base station (gNodeB or gNB) in a 5G system, and a base station in a 6G system. A base station can contain a Base Station Unit (BBU) and a Remote Radio Unit (RRU). The BBU and RRU can be located in different places; for example, the RRU can be deployed remotely to a high-traffic area, while the BBU is located in the central equipment room. Alternatively, the BBU and RRU can be located in the same equipment room. The BBU and RRU can also be different components within the same rack. Base stations can take the following forms: macro base stations, micro base stations (also known as small cells), pico base stations, relay stations, access points, balloon stations, etc.

[0159] Optionally, in some network device deployments, the network devices can adopt a centralized unit (CU) - distributed unit (DU) separation architecture, meaning that the network device can include a CU and / or a DU. The protocol layers in the network device's communication protocol stack are deployed in the CU and / or DU respectively. That is, some protocol layer functions are deployed in the CU for centralized control, while the remaining part or all protocol layer functions are deployed in the DU, which is centrally controlled by the CU.

[0160] Optionally, the CU and DU can be physically arranged together or physically separated, and this application embodiment does not limit this.

[0161] Optionally, in some network device deployments, the CU can also be divided into CU-control plane (CP) and CU-user plane (UP), etc.

[0162] Alternatively, in some deployments of the network equipment, the network equipment may also be an open radio access network (ORAN) architecture, etc. This application does not limit the specific deployment method of the network equipment.

[0163] For example, Figure 2 A schematic diagram of the CU-DU separation architecture of the network device provided in this application embodiment is shown, as follows: Figure 2 As shown, a network device may include a CU and at least one DU, each DU being connected to the CU via an F1 interface. Information exchange between different DUs can be accomplished through forwarding by the CU.

[0164] For example, the DU can support the functions of radio link control (RLC), media access control (MAC), and physical layer (PHY), while the CU can support the functions of radio resource control (RRC), packet data convergence protocol (PDCP), and service data adaptation protocol (SDAP).

[0165] It should be noted that the above examples of deploying protocol layers in the CU and DU are merely illustrative and should not constitute any limitation on this application. The protocol layers deployed in the CU and / or DU can also be existing protocols (e.g., the Long Term Evolution (LTE) protocol) or other protocol layers defined in future protocols, which are not limited in this application embodiment.

[0166] It should also be noted that the functions of each protocol layer mentioned in the embodiments of this application may change, and the embodiments of this application do not limit this.

[0167] It should be noted that the technical solution of this application is described using cell measurement as an example only in the embodiments of this application. However, the embodiments of this application are not limited to cell measurement. The ideas and process flow of the cell measurement method and device provided in the embodiments of this application can be similarly applied to the measurement method and device of reference signal.

[0168] Optionally, the cell measurement method and apparatus provided in this application are applicable to various application scenarios that require cell measurement.

[0169] For example, the cell measurement described in this application embodiment may include measuring the quality of the cell.

[0170] For example, Figure 3 A schematic diagram illustrating an application scenario provided by an embodiment of this application is shown. For example... Figure 3 As shown, cell 1 is the serving cell currently providing services to the terminal device, i.e., the source cell, and cells 2 to 6 are candidate cells that are available or detectable by the terminal device. The terminal device can use the cell measurement method provided in this application embodiment to measure the quality of the candidate cells and report the measurement results to the network device. The network device can determine whether the terminal device needs to switch from the current serving cell (i.e., the source cell) to a certain candidate cell (i.e., the target cell) based on the measurement results.

[0171] In existing technologies, network devices send measurement configurations to terminal devices, which then perform measurements on detectable cells based on these configurations. This results in a large number of measurement objects and measurements, leading to high energy consumption for the terminal devices.

[0172] This application provides a cell measurement method and apparatus. A network device sends a first indication message to a terminal device, the first indication message indicating that at least one candidate cell should be measured. The terminal device sends a first reporting message to the network device, the first reporting message indicating the measurement results of the at least one candidate cell. Based on the first reporting message, the network device sends a second indication message to the terminal device, the second indication message indicating that a first number of measurements should be performed on a first candidate cell within a first time period. The at least one candidate cell includes the first candidate cell, and the quality of the first candidate cell in the measurement results of the at least one candidate cell is greater than or equal to a first threshold value. The terminal device measures the first candidate cell based on the second indication message.

[0173] In other words, the terminal device measures and reports the measurement results of at least one candidate cell based on the first indication information of the network device, and performs the first number measurement of the first candidate cell within the first time period based on the second indication information of the network device. This allows for flexible control over the number of measurement objects and the number of measurements by the terminal device, which helps to reduce the energy consumption of the terminal device.

[0174] This application also provides another method and apparatus for cell measurement, wherein a terminal device measures at least one candidate cell; based on the measurement results of the at least one candidate cell, a first number measurement is performed on a first candidate cell within a first time period, wherein the at least one candidate cell includes the first candidate cell, and the quality of the first candidate cell in the measurement results of the at least one candidate cell is greater than or equal to a first threshold value.

[0175] In other words, the terminal device can perform the first measurement of the first candidate cell within the first time period based on the measurement results of at least one candidate cell. This allows for flexible control over the number of measurement objects and the number of measurements, which helps reduce the energy consumption of the terminal device.

[0176] It should be understood that the following description is for ease of understanding and explanation only, using the interaction between a terminal device and a network device as an example to illustrate the methods provided in the embodiments of this application. However, this should not constitute any limitation on the subject executing the methods provided in this application. For example, the terminal device shown in the embodiments below can be replaced by components (such as chips or circuits) configured in the terminal device. The network device shown in the embodiments below can also be replaced by components (such as chips or circuits) configured in the network device.

[0177] The embodiments shown below do not specifically limit the structure of the execution subject of the method provided in the embodiments of this application. As long as it is possible to communicate according to the method provided in the embodiments of this application by running a program that records the code of the method provided in the embodiments of this application, for example, the execution subject of the method provided in the embodiments of this application can be a terminal device or a network device, or a functional module in a terminal device or network device that can call and execute a program.

[0178] Figure 4 This is a schematic flowchart illustrating the cell measurement method 200 provided in this application embodiment from the perspective of device interaction. For example... Figure 4 As shown, method 200 may include steps S201 to S209. The steps of method 200 are described in detail below.

[0179] S201. Terminal equipment measurement service cell.

[0180] It should be noted that the serving cell is the cell currently providing service to this terminal device, i.e., the source cell.

[0181] In one possible implementation, the cell measurement described in this application embodiment may include measuring the quality of the cell.

[0182] Optionally, the measurement results of cell measurements (i.e., the measurement results of cell quality measurements) may include one or more of the following parameters: reference signal received power (RSRP), reference signal received quality (RSRQ), or signal to interference plus noise ratio (SINR).

[0183] S202. If the quality of the serving cell is lower than the threshold 1, the terminal device sends a reporting message 1 to the network device, which reports that the quality of the serving cell is lower than the threshold 1. Accordingly, the network device receives the reporting message 1 from the terminal device.

[0184] In other words, if the terminal device determines that the triggering conditions for reporting an LTM2 event are met, then the terminal device will report the LTM2 event to the network device.

[0185] Optionally, the terminal device can obtain the threshold value 1 in a variety of ways.

[0186] In one possible implementation, the threshold value 1 can be pre-configured.

[0187] For example, this threshold value of 1 can be pre-configured by the network device via an RRC message.

[0188] In another possible implementation, the terminal device can receive the threshold value 1 sent by other devices (such as other terminal devices).

[0189] For example, terminal device A can receive the threshold value 1 sent by terminal device B.

[0190] S203. Based on the reporting message 1, the network device sends a first indication message to the terminal device, the first indication message indicating that at least one candidate cell needs to be measured. Accordingly, the terminal device receives the first indication message from the network device.

[0191] In one possible implementation, the first indication information may be a radio resource control (RRC) message, or may be carried in an RRC message.

[0192] Optionally, the first indication information may be a medium access control (MAC) control element (CE) or downlink control information (DCI).

[0193] In one possible implementation, the first indication information may include at least one measurement identifier, which corresponds one-to-one with the at least one candidate cell, and each measurement identifier is used to indicate whether it is necessary to measure the candidate cell corresponding to each measurement identifier.

[0194] For example, the first indication information may include at least one bit, which corresponds one-to-one with the at least one candidate cell, and the value of each bit in the at least one bit is used to represent the measurement identifier of the candidate cell corresponding to each bit.

[0195] For example, taking MAC CE1 as the first indication information, Figure 5 A schematic diagram of the format of MACCE1 provided in an embodiment of this application is shown. For example... Figure 5 As shown, MAC CE1 includes 8 bits: C1 to C8, where C1 corresponds to candidate cell 1 (i.e., the first candidate cell), C2 corresponds to candidate cell 2, ..., and C8 corresponds to candidate cell 8. A value of "1" for C1 (i.e., the measurement identifier for candidate cell 1) indicates that candidate cell 1 needs to be measured, a value of "1" for C2 indicates that candidate cell 2 needs to be measured, ..., and a value of "1" for C8 indicates that candidate cell 8 needs to be measured.

[0196] It should be noted that, Figure 5 The MAC CE1 is shown schematically to include 8 bits, all of which are "1", but the embodiments of this application are not limited to this. Optionally, the MAC CE1 may also include other numbers of bits, each of which can be "0" or "1". A bit value of "0" indicates that the candidate cell corresponding to that bit does not need to be measured, and the embodiments of this application do not limit this.

[0197] S204. The terminal device sends a reporting message 2 (i.e., a first reporting message) to the network device, the reporting message 2 indicating the measurement results of the at least one candidate cell. Accordingly, the network device receives the reporting message 2 from the terminal device.

[0198] Optionally, before sending the reporting message 2 to the network device, the method 200 may further include: the terminal device performing a measurement on the at least one candidate cell based on the first indication information to obtain the measurement result of the at least one candidate cell.

[0199] Optionally, the measurement result may include at least one of RSRP, RSRQ, or SINR.

[0200] S205. Based on the reporting message 2, the network device sends a second instruction message to the terminal device. The second instruction message is used to instruct a first-time measurement of the first candidate cell within a first time period. The at least one candidate cell includes the first candidate cell, and the quality of the first candidate cell in the measurement results of the at least one candidate cell is greater than or equal to a threshold value 2 (i.e., the first threshold value). Accordingly, the terminal device receives the reporting message 2 from the network device.

[0201] Alternatively, the network device can obtain the threshold value 2 in a variety of ways.

[0202] In one possible implementation, the threshold value 2 can be preset.

[0203] In another possible implementation, the network device can receive the threshold value 2 sent by other devices (such as other network devices).

[0204] For example, network device A can receive the threshold value 2 sent by network device B.

[0205] In one possible implementation, the second instruction information can be MAC CE or DCI.

[0206] In one possible implementation, the second indication information may include first count information and time information, wherein the first count information is used to indicate the first count and the time information is used to indicate the first time period.

[0207] In one possible implementation, the second indication information may also include at least one measurement identifier.

[0208] For example, the second indication information may include at least one bit of measurement identifier, N bits of time information, and M bits of first count information corresponding to the first candidate cell, where M and N are both greater than 0.

[0209] For example, taking MAC CE2 as the second indication information, Figure 6 A schematic diagram of the MACCE2 format provided in an embodiment of this application is shown. For example... Figure 6As shown, MAC CE2 includes 8 bits of measurement identifiers: C1 to C8. C1 corresponds to candidate cell 1 (i.e., the first candidate cell), C2 corresponds to candidate cell 2, ..., and C8 corresponds to candidate cell 8. A value of "1" for C1 (i.e., the measurement identifier for candidate cell 1) indicates that candidate cell 1 needs to be measured; a value of "1" for C2 indicates that candidate cell 2 needs to be measured, ..., and a value of "1" for C8 indicates that candidate cell 8 needs to be measured. MAC CE2 also includes 4 bits of first count information corresponding to C1. This first count information includes 4 bits with a value of "1111", indicating the first count (e.g., ...). Figure 6 N in C1 The first time interval is 15 times. MAC CE2 also includes 8 bits of time information, which are "01100100", indicating that the first time interval is 100ms.

[0210] It should also be noted that, Figure 6 The first count information corresponding to C1 (i.e., candidate cell 1) in MAC CE2 is used to indicate N. C1 This example is used for illustration, but the embodiments of this application are not limited thereto. Optionally, MAC CE2 may also include: count information (used to indicate N) corresponding to at least one bit from C2 to C8 (i.e., at least one candidate cell from candidate cell 2 to candidate cell 8). C2 ~N C8 (at least one), but this application embodiment does not limit this.

[0211] Optionally, the at least one candidate cell may further include a second candidate cell, and the second indication information is further used to indicate that a second number of measurements of the second candidate cell is performed during the first time period, the first number being greater than the second number, and the quality of the second candidate cell in the measurement results of the at least one candidate cell being less than the first threshold value.

[0212] Optionally, the second indication information may also include a second number information, which is used to indicate the second number.

[0213] For example, the second indication information may include at least one bit of measurement identifier, N bits of time information, M bits of first count information corresponding to the first candidate cell, and M bits of second count information corresponding to the second candidate cell, where M and N are both greater than 0.

[0214] For example, taking MAC CE2 as the second indication information, Figure 7 A schematic diagram of another format of MACCE2 provided in an embodiment of this application is shown. For example... Figure 7As shown, MAC CE2 includes 8 bits of measurement identifiers: C1 to C8. C1 corresponds to candidate cell 1 (i.e., the first candidate cell), C2 corresponds to candidate cell 2, ..., and C8 corresponds to candidate cell 8. A value of "1" for C1 (i.e., the measurement identifier for candidate cell 1) indicates that candidate cell 1 needs to be measured; a value of "1" for C2 indicates that candidate cell 2 needs to be measured, ..., and a value of "1" for C8 indicates that candidate cell 8 needs to be measured. MAC CE2 also includes 4 bits of first count information corresponding to C1. This first count information includes 4 bits with a value of "1111", indicating the first count (e.g., ...). Figure 7 N in C1 The number is 15. MAC CE2 also includes a second count information of 4 bits corresponding to C2. This second count information includes 4 bits with a value of "0010", indicating the second count (e.g., ...). Figure 7 N in C2 The first time interval is 100ms. MAC CE2 also includes 8 bits of time information, which are "01100100", indicating that the first time interval is 100ms.

[0215] It should be noted that, Figure 6 and Figure 7 The MAC CE2 is shown schematically as including an 8-bit measurement identifier, with all 8 bits set to "1". However, this embodiment is not limited to this. Optionally, the MAC CE2 may also include other numbers of measurement identifiers, with each bit set to either "0" or "1". A bit set to "0" indicates that the candidate cell corresponding to that bit does not need to be measured. Accordingly, the count information corresponding to a measurement identifier with a value of "0" in the MAC CE2 may be 0, or the count information for the 4 bits corresponding to a measurement identifier with a value of "0" may not be carried. This embodiment does not limit this.

[0216] It should also be noted that, Figure 6 and Figure 7 The illustration only shows that MAC CE2 includes 8 bits of time information and 4 bits of count information (such as first count information or second count information), but the embodiments of this application are not limited to this. Optionally, MAC CE2 may also include other amounts of time information and / or count information, and the embodiments of this application do not limit this.

[0217] It should also be noted that, Figure 7 The first count information (used to indicate the first count N) is only included in MAC CE2, specifically for C1 (i.e., candidate cell 1). C1The second number information corresponding to C2 (i.e., candidate cell 2) and C2 (used to indicate the second number N) C2 This example is used for illustration, but the embodiments of this application are not limited thereto. Optionally, MAC CE2 may also include: count information corresponding to at least one bit from C3 to C8 (i.e., at least one candidate cell from candidate cell 3 to candidate cell 8) (used to indicate N). C3 ~N C8 (at least one of them), but this application embodiment does not limit this.

[0218] S206. Based on the indication information 2, the terminal device performs the first measurement of the first candidate cell within the first time period.

[0219] Optionally, the method 200 may further include: the terminal device measuring the second number of the second candidate cell within the first time period based on the indication information 2.

[0220] Optionally, the second number can be greater than or equal to 0.

[0221] In one possible implementation, if the number of at least one candidate cells is greater than 1, and the second count is equal to 0, it can be understood that during the first time period, the terminal device only needs to perform the first count measurement on the candidate cells with good quality among the at least one candidate cells, without needing to measure the candidate cells with poor quality among the at least one candidate cells. This reduces the number of measurement objects, thereby reducing the energy consumption of the terminal device.

[0222] Optionally, in this embodiment of the application, the terminal device performs a high number of measurements on the candidate cells with good quality among the at least one candidate cells during the first time period, or it can be replaced by the terminal device performing a first cycle of measurements on the candidate cells with good quality among the at least one candidate cells.

[0223] In another possible implementation, when the number of at least one candidate cells is greater than 1, if the second number is greater than 0 and the first number is greater than the second number, it can be understood that within the first time period, the terminal device performs a high number of measurements on the candidate cells with good quality among the at least one candidate cells, and performs a low number of measurements on the candidate cells with poor quality among the at least one candidate cells. This reduces the total number of cell measurements, thereby reducing the power consumption of the terminal device.

[0224] Optionally, in the embodiments of this application, during the first time period, the terminal device performs a high number of measurements on the candidate cells with good quality among the at least one candidate cells, which can be replaced by the terminal device performing short-cycle measurements (i.e., high-frequency measurements) on the candidate cells with good quality among the at least one candidate cells; or, the terminal device performs a low number of measurements on the candidate cells with poor quality among the at least one candidate cells, which can be replaced by the terminal device performing long-cycle measurements (i.e., low-frequency measurements) on the candidate cells with poor quality among the at least one candidate cells.

[0225] Alternatively, prior to S206, the terminal device could determine the need to initiate a measurement GAP in a variety of ways.

[0226] In one possible implementation, the terminal device determines that the first candidate cell and the serving cell belong to inter-frequency cells or inter-system cells; and initiates the measurement gap. That is, the terminal device can determine on its own whether it needs to initiate the measurement gap.

[0227] In another possible implementation, the second indication information is also used to instruct the initiation of a measurement gap, based on which the terminal device initiates the measurement gap. That is, the network device determines that the first candidate cell and the serving cell belong to an inter-frequency cell or an inter-system cell, and the terminal device can initiate the measurement gap based on the network device's instruction.

[0228] Optionally, the second indication information may further include Q-bit GAP indication information, which is used to indicate whether to initiate a measurement GAP, where Q is greater than 0.

[0229] For example, taking MAC CE2 as the second indication information, Figure 8 Another schematic diagram of the MACCE2 provided in this application embodiment is shown. For example... Figure 8 As shown, MAC CE2 includes 8 bits of measurement identifiers: C1 to C8. C1 corresponds to candidate cell 1 (i.e., the first candidate cell), C2 corresponds to candidate cell 2, ..., and C8 corresponds to candidate cell 8. A value of "1" for C1 (i.e., the measurement identifier for candidate cell 1) indicates that candidate cell 1 needs to be measured; a value of "1" for C2 indicates that candidate cell 2 needs to be measured, ..., and a value of "1" for C8 indicates that candidate cell 8 needs to be measured. MAC CE2 also includes 4 bits of first count information corresponding to C1. This first count information includes 4 bits with a value of "1111", indicating the first count (e.g., ...). Figure 8 N in C1 The number is 15. MAC CE2 also includes a second count information of 4 bits corresponding to C2. This second count information includes 4 bits with a value of "0010", indicating the second count (e.g., ...). Figure 8 N in C2 The first time interval is 100ms. The MAC CE2 also includes 7 bits of time information, with a value of "1100100", indicating that the first time interval is 100ms. The MAC CE2 also includes 1 bit of GAP indication information, with a value of "1", indicating that a measurement GAP needs to be initiated.

[0230] It should be noted that, Figure 8 The MAC CE2 is shown schematically as including an 8-bit measurement identifier, with all 8 bits set to "1". However, this embodiment is not limited to this. Optionally, the MAC CE2 may also include other numbers of measurement identifiers, with each bit set to either "0" or "1". A bit set to "0" indicates that the candidate cell corresponding to that bit does not need to be measured. Accordingly, the count information corresponding to a measurement identifier with a value of "0" in the MAC CE2 may be 0, or the count information for the 4 bits corresponding to a measurement identifier with a value of "0" may not be carried. This embodiment does not limit this.

[0231] It should also be noted that, Figure 8 The illustration only shows that MAC CE2 includes 8 bits of time information and 4 bits of count information (such as first count information or second count information), but the embodiments of this application are not limited to this. Optionally, MAC CE2 may also include other amounts of time information and / or count information, and the embodiments of this application do not limit this.

[0232] It should also be noted that, Figure 8 The first count information (used to indicate the first count N) is only included in MAC CE2, specifically for C1 (i.e., candidate cell 1). C1 The second number information corresponding to C2 (i.e., candidate cell 2) and C2 (used to indicate the second number N) C2 This example is used for illustration, but the embodiments of this application are not limited thereto. Optionally, MAC CE2 may also include: count information corresponding to at least one bit from C3 to C8 (i.e., at least one candidate cell from candidate cell 3 to candidate cell 8) (used to indicate N). C3 ~N C8 (at least one of them), but this application embodiment does not limit this.

[0233] It should also be noted that, Figure 8The illustration only shows MAC CE2 including 7 bits of time information and 1 bit of GAP indication information, but the embodiments of this application are not limited to this. Optionally, MAC CE2 may also include other amounts of time information and / or GAP indication information, and the embodiments of this application do not limit this.

[0234] S207. The terminal device sends a reporting message 3 to the network device, which reports the measurement results of the first candidate cell. Accordingly, the network device receives the reporting message 3 from the terminal device.

[0235] Repeat steps S206 and S207 until the network device initiates a handover command to the terminal device, or the terminal device receives a handover command from the network device.

[0236] S208. If the quality of the first candidate cell is measured to be better than the quality of the serving cell during the first time period, the terminal device sends a reporting message 4 to the network device, the reporting message 4 being used to report that the quality of the first candidate cell is better than the quality of the serving cell. Accordingly, the network device receives the reporting message 4 from the terminal device.

[0237] In other words, if the terminal device determines that the triggering conditions for reporting an LTM3 event are met, then the terminal device will report an LTM3 event to the network device.

[0238] S209. If, during the first time period, the quality of the first candidate cell is measured to be greater than or equal to threshold 3, and the quality of the serving cell is less than or equal to threshold 4, then the terminal device sends a reporting message 5 to the network device. This reporting message 5 reports that the quality of the first candidate cell is greater than or equal to threshold 3 and the quality of the serving cell is less than or equal to threshold 4. Correspondingly, the network device receives the reporting message 5 from the terminal device.

[0239] In other words, if the terminal device determines that the triggering conditions for reporting an LTM5 event are met, then the terminal device will report the LTM5 event to the network device.

[0240] Optionally, the terminal device can obtain the threshold value 3 or the threshold value 4 in a variety of ways.

[0241] In one possible implementation, the threshold value 3 or the threshold value 4 can be pre-configured.

[0242] For example, the threshold value 3 or the threshold value 4 can be pre-configured by the network device via an RRC message.

[0243] In another possible implementation, the terminal device may receive the threshold value 3 or the threshold value 4 sent by other devices (such as other terminal devices).

[0244] For example, terminal device A can receive the threshold value 3 or the threshold value 4 sent by terminal device B.

[0245] Figure 9 This is a schematic flowchart illustrating the cell measurement method 300 provided in this application embodiment from the perspective of device interaction. For example... Figure 9 As shown, method 300 may include steps S301 to S306. The steps of method 300 are described in detail below.

[0246] S301. The terminal device measures at least one candidate cell.

[0247] In one possible implementation, in S301, the terminal device performs a measurement on at least one candidate cell.

[0248] For example, the measurement result may include at least one of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), or signal-to-interference-plus-noise ratio (SINR).

[0249] S302. The terminal device sends a second reporting message to the network device, the second reporting message indicating that a first candidate cell needs to be measured, the at least one candidate cell including the first candidate cell, and the quality of the first candidate cell in the measurement results of the at least one candidate cell is greater than or equal to a first threshold value. Accordingly, the network device receives the second reporting message from the terminal device.

[0250] Optionally, the terminal device may obtain the first threshold value in a variety of ways.

[0251] In one possible implementation, the first threshold value can be pre-configured.

[0252] For example, this first threshold value can be pre-configured by the network device via an RRC message.

[0253] In another possible implementation, the terminal device may receive the first threshold value sent by other devices (such as other terminal devices).

[0254] For example, terminal device A can receive the first threshold value sent by terminal device B.

[0255] Optionally, the number of candidate cells with quality greater than or equal to the first threshold value in the measurement results of the at least one candidate cell can be multiple, such as including a first candidate cell and a third candidate cell, that is, the terminal device reports that the first candidate cell and the third candidate cell need to be measured.

[0256] Optionally, the terminal device can report the need to measure the first candidate cell and the third candidate cell in various ways.

[0257] In one possible implementation, after measuring the at least one candidate cell, the terminal device can report via a reporting message that it needs to measure the first candidate cell and the third candidate cell.

[0258] For example, the second reporting message is also used to indicate that the third candidate cell needs to be measured.

[0259] In another possible implementation, after measuring the quality of the first candidate cell to be greater than or equal to a first threshold value, the terminal device may report the need to measure the first candidate cell through a reporting message, and after measuring the quality of the third candidate cell to be greater than or equal to the first threshold value, it may report the need to measure the third candidate cell through another reporting message.

[0260] For example, S302 may include: when the quality of the first candidate cell among the at least one candidate cells is measured to be greater than or equal to the first threshold value, the terminal device sends the second reporting message to the network device; the method 300 may further include: when the quality of the third candidate cell among the at least one candidate cells is measured to be greater than or equal to the first threshold value, the terminal device sends a third reporting message to the network device, the third reporting message indicating that the third candidate cell needs to be measured. Accordingly, the network device receives the third reporting message from the terminal device.

[0261] Optionally, the first time period and / or the first threshold value are pre-configured.

[0262] S303. Based on the measurement results of the at least one candidate cell, the terminal device performs a first-time measurement of the first candidate cell within a first time period.

[0263] Optionally, the at least one candidate cell further includes a second candidate cell, and the method 300 may further include: the terminal device, based on the measurement results of the at least one candidate cell, performs a second measurement of the second candidate cell within the first time period, wherein the quality of the second candidate cell in the measurement results of the at least one candidate cell is less than the first threshold value, and the first number is greater than the second number.

[0264] Optionally, the second number can be greater than or equal to 0.

[0265] In one possible implementation, if the number of at least one candidate cells is greater than 1, and the second number is equal to 0, it can be understood that during the first time period, the terminal device only needs to measure the candidate cells with good quality among the at least one candidate cells, and does not need to measure the candidate cells with poor quality among the at least one candidate cells. In this way, the number of measurement objects can be reduced, thereby reducing the energy consumption of the terminal device.

[0266] Optionally, in this embodiment of the application, the terminal device performs a high number of measurements on the candidate cells with good quality among the at least one candidate cells during the first time period, or it can be replaced by the terminal device performing a first cycle of measurements on the candidate cells with good quality among the at least one candidate cells.

[0267] In another possible implementation, when the number of at least one candidate cells is greater than 1, if the second number is greater than 0 and the first number is greater than the second number, it can be understood that within the first time period, the terminal device needs to perform a high number of measurements on the candidate cells with good quality among the at least one candidate cells, and a low number of measurements on the candidate cells with poor quality among the at least one candidate cells. This reduces the total number of cell measurements, thereby reducing the energy consumption of the terminal device.

[0268] Optionally, in the embodiments of this application, during the first time period, the terminal device performs a high number of measurements on the candidate cells with good quality among the at least one candidate cells, which can be replaced by the terminal device performing short-cycle measurements (i.e., high-frequency measurements) on the candidate cells with good quality among the at least one candidate cells; or, the terminal device performs a low number of measurements on the candidate cells with poor quality among the at least one candidate cells, which can be replaced by the terminal device performing long-cycle measurements (i.e., low-frequency measurements) on the candidate cells with poor quality among the at least one candidate cells.

[0269] Optionally, the method 300 may further include: if the terminal device determines that the first candidate cell and the serving cell belong to inter-frequency cells or inter-system cells; initiate a measurement gap. That is, the terminal device can determine whether to initiate a measurement gap itself.

[0270] S304. The terminal device sends a fourth reporting message to the network device, the fourth reporting message being used to report the measurement results of the first candidate cell. Correspondingly, the network device receives the fourth reporting message from the terminal device.

[0271] Repeat steps S303 and S304 until the network device initiates a handover command to the terminal device, or the terminal device receives a handover command from the network device.

[0272] S305. If, during the first time period, the quality of the first candidate cell is measured to be better than the quality of the current serving cell, the terminal device sends a fifth reporting message to the network device, the fifth reporting message being used to report that the quality of the first candidate cell is better than the quality of the serving cell. Accordingly, the network device receives the fifth reporting message from the terminal device.

[0273] In other words, if the terminal device determines that the triggering conditions for reporting an LTM3 event are met, then the terminal device will report an LTM3 event to the network device.

[0274] S306. If, during the first time period, the quality of the first candidate cell is measured to be greater than or equal to threshold 3, and the quality of the serving cell is less than or equal to threshold 4, then the terminal device sends a sixth reporting message to the network device. This sixth reporting message reports that the quality of the first candidate cell is greater than or equal to threshold 3 and the quality of the serving cell is less than or equal to threshold 4. Correspondingly, the network device receives the sixth reporting message from the terminal device.

[0275] In other words, if the terminal device determines that the triggering conditions for reporting an LTM5 event are met, then the terminal device will report the LTM5 event to the network device.

[0276] Optionally, the terminal device can obtain the threshold value 3 or the threshold value 4 in a variety of ways.

[0277] In one possible implementation, the threshold value 3 or the threshold value 4 can be pre-configured.

[0278] For example, the threshold value 3 or the threshold value 4 can be pre-configured by the network device via an RRC message.

[0279] In another possible implementation, the terminal device may receive the threshold value 3 or the threshold value 4 sent by other devices (such as other terminal devices).

[0280] For example, terminal device A can receive the threshold value 3 or the threshold value 4 sent by terminal device B.

[0281] Optionally, after receiving the cell measurement results reported by the terminal device (such as the reporting message 3 in method 200, or the fourth reporting message in method 300), the network device can further determine whether the terminal device needs to switch cells (i.e., switch from the current serving cell to a candidate cell). If a switch is required, the network device sends a switch command to the terminal device.

[0282] Optionally, when the network equipment adopts a CU-DU separated architecture, the cell handover command can be generated by either the CU or the DU.

[0283] In one possible implementation, the DU determines and generates the handover command, which is a cell handover within the same DU (the source cell and the target cell belong to the same DU).

[0284] For example, the DU receives an LTM3 or LTM5 event reported by the terminal device and determines whether to trigger a handover command based on the reported LTM3 or LTM5 event.

[0285] In another possible implementation, the CU determines and generates the handover command, which is a cell handover across DUs within the same CU (the source cell and the target cell belong to different DUs under the same CU). Communication between the CU and the terminal device needs to be forwarded through the DU.

[0286] For example, the DU receives LTM3 or LTM5 events reported by the terminal device and sends report information to the CU. The report information includes the quality of the serving cell and the quality of the candidate cells measured within the first time period reported by the terminal device. Based on the report information, the CU determines whether to trigger a handover command.

[0287] Figure 10 This is a schematic flowchart illustrating the cell measurement method 400 provided in this application embodiment from the perspective of device interaction. For example... Figure 10 As shown, method 400 may include steps S401 to S403. The steps of method 400 are described in detail below.

[0288] S401. The network device sends first indication information to the terminal device, the first indication information indicating that at least one candidate cell needs to be measured. Accordingly, the terminal device receives the first indication information from the network device.

[0289] S402. The terminal device sends a first reporting message to the network device, the first reporting message indicating the measurement results of the at least one candidate cell. Accordingly, the network device receives the first reporting message from the terminal device.

[0290] S403. Based on the first reporting message, the network device sends second indication information to the terminal device. The second indication information is used to indicate that a first number measurement of the first candidate cell is performed within a first time period. The at least one candidate cell includes the first candidate cell, and the quality of the first candidate cell in the measurement results of the at least one candidate cell is greater than or equal to a first threshold value. Accordingly, the terminal device receives the second indication information from the network device.

[0291] In one possible implementation, the second indication information includes first count information and time information, wherein the first count information is used to indicate the first count, and the time information is used to indicate the first time period.

[0292] In one possible implementation, the second indication information may also include at least one measurement identifier.

[0293] Optionally, the at least one candidate cell further includes a second candidate cell, and the second indication information is also used to indicate that a second number of measurements of the second candidate cell is performed within the first time period, the first number of measurements being greater than the second number of measurements, and the quality of the second candidate cell in the measurement results of the at least one candidate cell being less than the first threshold value.

[0294] In one possible implementation, the second indication information further includes second count information, which is used to indicate the second count.

[0295] Optionally, the second indication information can be MAC CE or DCI.

[0296] Optionally, the method 400 may further include: the terminal device measuring the first candidate cell the first number of times within the first time period based on the second indication information.

[0297] Optionally, the method 400 may further include: the terminal device measuring the second number of the second candidate cell within the first time period based on the second indication information.

[0298] Optionally, the second number can be greater than or equal to 0.

[0299] In one possible implementation, if the number of at least one candidate cells is greater than 1, and the second count is equal to 0, it can be understood that during the first time period, the terminal device only needs to perform the first count measurement on the candidate cells with good quality among the at least one candidate cells, without needing to measure the candidate cells with poor quality among the at least one candidate cells. This reduces the number of measurement objects, thereby reducing the energy consumption of the terminal device.

[0300] Optionally, in this embodiment of the application, the terminal device performs a high number of measurements on the candidate cells with good quality among the at least one candidate cells during the first time period, or it can be replaced by the terminal device performing a first cycle of measurements on the candidate cells with good quality among the at least one candidate cells.

[0301] In another possible implementation, when the number of at least one candidate cells is greater than 1, if the second number is greater than 0 and the first number is greater than the second number, it can be understood that within the first time period, the terminal device performs a high number of measurements on the candidate cells with good quality among the at least one candidate cells, and performs a low number of measurements on the candidate cells with poor quality among the at least one candidate cells. This reduces the total number of cell measurements, thereby reducing the power consumption of the terminal device.

[0302] Optionally, in the embodiments of this application, during the first time period, the terminal device performs a high number of measurements on the candidate cells with good quality among the at least one candidate cells, which can be replaced by the terminal device performing short-cycle measurements (i.e., high-frequency measurements) on the candidate cells with good quality among the at least one candidate cells; or, the terminal device performs a low number of measurements on the candidate cells with poor quality among the at least one candidate cells, which can be replaced by the terminal device performing long-cycle measurements (i.e., low-frequency measurements) on the candidate cells with poor quality among the at least one candidate cells.

[0303] Optionally, before the terminal device performs the first measurement of the first candidate cell within the first time period, the terminal device may determine in various ways whether or not to initiate a measurement gap.

[0304] In one possible implementation, the terminal device determines that the first candidate cell and the serving cell belong to inter-frequency cells or inter-system cells; and initiates the measurement gap. That is, the terminal device can determine on its own whether it needs to initiate the measurement gap.

[0305] In another possible implementation, the second indication information is also used to instruct the initiation of a measurement gap, based on which the terminal device initiates the measurement gap. That is, the network device determines that the first candidate cell and the serving cell belong to an inter-frequency cell or an inter-system cell, and the terminal device can initiate the measurement gap based on the network device's instruction.

[0306] Optionally, the method 400 may further include: the terminal device sending a reporting message 3 to the network device, the reporting message 3 being used to report the measurement results of the first candidate cell. Correspondingly, the network device receives the reporting message 3 from the terminal device.

[0307] Optionally, the method 400 may further include: if the quality of the first candidate cell is measured to be better than the quality of the serving cell during the first time period, the terminal device sends a reporting message 4 to the network device, the reporting message 4 being used to report that the quality of the first candidate cell is better than the quality of the serving cell. Accordingly, the network device receives the reporting message 4 from the terminal device.

[0308] Optionally, the method 400 may further include: if the quality of the first candidate cell is measured to be greater than or equal to threshold 3 and the quality of the serving cell is less than or equal to threshold 4 within the first time period, then the terminal device sends a reporting message 5 to the network device, the reporting message 5 being used to report that the quality of the first candidate cell is greater than or equal to threshold 3 and the quality of the serving cell is less than or equal to threshold 4. Accordingly, the network device receives the reporting message 5 from the terminal device.

[0309] It should be noted that the descriptions of each step in method 400 can be found in the descriptions of the corresponding steps in method 200. To avoid repetition, they will not be repeated here.

[0310] Figure 11 This is a schematic flowchart illustrating the cell measurement method 500 provided in this application embodiment from the perspective of device interaction. For example... Figure 11 As shown, the method 500 may include steps S501 to S502. The steps of method 500 are described in detail below.

[0311] S501. The terminal device measures at least one candidate cell.

[0312] S502. Based on the measurement results of the at least one candidate cell, the terminal device performs a first-time measurement of the first candidate cell within a first time period. The at least one candidate cell includes the first candidate cell, and the quality of the first candidate cell in the measurement results of the at least one candidate cell is greater than or equal to a first threshold value.

[0313] Optionally, the number of candidate cells with quality greater than or equal to the first threshold value in the measurement results of the at least one candidate cell can be multiple, such as including a first candidate cell and a third candidate cell, that is, the terminal device reports that the first candidate cell and the third candidate cell need to be measured.

[0314] Optionally, the terminal device can report the need to measure the first candidate cell and the third candidate cell in various ways.

[0315] In one possible implementation, after measuring the at least one candidate cell, the terminal device can report via a reporting message that it needs to measure the first candidate cell and the third candidate cell.

[0316] In another possible implementation, after measuring the quality of the first candidate cell to be greater than or equal to a first threshold value, the terminal device may report the need to measure the first candidate cell through a reporting message, and after measuring the quality of the third candidate cell to be greater than or equal to the first threshold value, it may report the need to measure the third candidate cell through another reporting message.

[0317] Optionally, the first time period and / or the first threshold value are pre-configured.

[0318] Optionally, prior to S502, the method 500 may further include: sending a second reporting message to the network device, the second reporting message indicating that the first candidate cell needs to be measured.

[0319] Optionally, the method 500 may further include: the terminal device performing a first number measurement on the first candidate cell within a first time period based on the measurement results of the at least one candidate cell.

[0320] Optionally, the at least one candidate cell further includes a second candidate cell, and the method 500 may further include: based on the measurement results of the at least one candidate cell, performing a second measurement of the second candidate cell within the first time period, wherein the quality of the second candidate cell in the measurement results of the at least one candidate cell is less than the first threshold value, and the first number is greater than the second number.

[0321] Optionally, the second number can be greater than or equal to 0.

[0322] The terminal device sends a fourth reporting message to the network device, which is used to report the measurement results of the first candidate cell.

[0323] Optionally, before the terminal device performs the first number measurement of the first candidate cell within a first time period based on the measurement results of the at least one candidate cell, the method 500 may further include: determining that the first candidate cell and the current serving cell belong to inter-frequency cells or inter-system cells; and initiating a measurement gap.

[0324] Optionally, the method 500 may further include: the terminal device sending a fourth reporting message to the network device, the fourth reporting message being used to report the measurement results of the first candidate cell.

[0325] Optionally, the method 500 may further include: if, during the first time period, the quality of the first candidate cell is found to be better than the quality of the current serving cell, then the terminal device sends a fifth reporting message to the network device, the fifth reporting message being used to report that the quality of the first candidate cell is better than the quality of the serving cell. Accordingly, the network device receives the fifth reporting message from the terminal device.

[0326] Optionally, the method 500 may further include: if the quality of the first candidate cell is measured to be greater than or equal to threshold 3 and the quality of the serving cell is less than or equal to threshold 4 during the first time period, then the terminal device sends a sixth reporting message to the network device, the sixth reporting message being used to report that the quality of the first candidate cell is greater than or equal to threshold 3 and the quality of the serving cell is less than or equal to threshold 4.

[0327] Optionally, the network devices in method 400 and / or method 500 may also adopt a CU-DU separation architecture. For details, please refer to the description of the corresponding parts in method 200 and / or method 300 above.
