Description

Technical Field

[0001] This invention relates to the field of communications, and more particularly to a communication method and a communication device. Background Technology

[0002] In mobile communication systems, the movement of terminal devices causes changes in the communication link between them and access network equipment. The access network equipment then instructs the terminal device to perform cell handover based on its movement. To reduce handover latency and further enhance service continuity, the concept of Layer 1 / L2 triggered mobility (LTM) handover mechanism has been proposed. LTM handover mechanism refers to cell handover operations primarily occurring at the physical layer (PHY) and media access control (MAC) layers. In LTM handover mechanism, the access network equipment performs cell handover based on the beam measurement results (i.e., L1 measurement results) reported by the terminal device. However, when beam measurement results change rapidly or the terminal device moves quickly, it may fail to report measurements in a timely manner, resulting in the terminal device being unable to perform cell synchronization or cell handover in a timely manner. Summary of the Invention

[0003] This application provides a communication method and a communication device, which facilitates timely cell synchronization or cell handover for terminal devices.

[0004] In a first aspect, this application provides a communication method, the method comprising:

[0005] Signal measurements were performed on multiple beams in the first cell;

[0006] In response to at least one first beam among N beams, a measurement report is sent to the access network device; the N beams are N of a plurality of beams, where N is an integer greater than 1; the first beam is the beam that satisfies the reporting conditions of the measurement event; the measurement report includes at least one of the following: the measurement event satisfied by the first beam, the identifier of the first beam, the signal quality of the first beam, and the identifier of the cell corresponding to the first beam.

[0007] Based on the method described in the first aspect, it is beneficial for terminal equipment to report measurements in a timely manner, which in turn is beneficial for terminal equipment to perform cell synchronization or cell handover in a timely manner.

[0008] In one possible embodiment, the N beams are the N beams with the best signal quality among a plurality of beams.

[0009] Based on this possible implementation, it is beneficial for terminal devices to report measurements in a timely manner, thereby facilitating timely cell synchronization or cell handover.

[0010] In one possible embodiment, before performing signal measurements on multiple beams of the first cell, the method further includes receiving indication information from an access network device, the indication information indicating the first cell to be measured, the measurement event, the reporting conditions of the measurement event, and the value of N.

[0011] Based on this possible implementation, the first cell to be measured, the measurement event, the reporting conditions of the measurement event, and the value of N can be configured more flexibly.

[0012] In one possible embodiment, the measurement report also includes information about a second beam, which is one of the N beams that satisfies the measurement event but does not meet the reporting conditions.

[0013] In one possible embodiment, the information of the second beam includes at least one of the following: the identifier of the second beam, the signal quality of the second beam, the identifier of the cell corresponding to the second beam, and the duration of the second beam satisfying the measurement event.

[0014] Based on this possible embodiment, the access network device can obtain beam information that meets the reporting conditions of the measurement event but does not meet the reporting conditions of the measurement event. It can have a more comprehensive understanding of the beam information, which can be used to decide whether the terminal should perform cell synchronization or select the beam for cell synchronization, or decide whether the terminal should perform cell handover or select the beam for cell handover.

[0015] Secondly, this application provides a communication method, the method comprising:

[0016] Receive a measurement report from the terminal device; the measurement report includes at least one of the following: the measurement event satisfied by the first beam, the identifier of the first beam, the signal quality of the first beam, and the identifier of the cell corresponding to the first beam; the first beam is the beam among the N beams of the first cell that satisfies the reporting conditions of the measurement event, where N is an integer greater than 1, and the N beams are used to evaluate whether the reporting conditions of the measurement event are met.

[0017] In one possible embodiment, the N beams are the N beams with the best signal quality among the beams of the first cell.

[0018] In one possible embodiment, before receiving a measurement report from the terminal device, an instruction message may be sent to the terminal device, indicating the first cell to be measured, the measurement event, the reporting conditions of the measurement event, and the value of N.

[0019] In one possible embodiment, the measurement report also includes information about a second beam, which is one of the N beams that satisfies the measurement event but does not meet the reporting conditions.

[0020] In one possible embodiment, the information of the second beam includes at least one of the following: the identifier of the second beam, the signal quality of the second beam, the identifier of the cell corresponding to the second beam, and the duration of the second beam satisfying the measurement event.

[0021] The beneficial effects of the second aspect can be compared with the beneficial effects of the first aspect, and will not be elaborated here.

[0022] Thirdly, this application provides a communication method, the method comprising:

[0023] Whether a measurement event is satisfied is determined based on the beam signal quality of the serving cell; wherein the beam signal quality of the serving cell is determined in any of the following ways:

[0024] The beam signal quality of the serving cell is the average of the signal quality of the M best beams of the serving cell, where M is an integer greater than 1; or,

[0025] The signal quality of the serving cell's beam is the average of the signal quality of all beams in the serving cell; or,

[0026] The beam signal quality of the serving cell is the average of the signal quality of the X best first beams of the serving cell, where X is an integer greater than or equal to 1, and the first beams are the beams of the serving cell whose signal quality exceeds a threshold value T; or,

[0027] The signal quality of the serving cell is the average of the signal quality of all first beams in the serving cell. The number of first beams is less than X, and the first beams are the beams whose signal quality exceeds a threshold T. Alternatively,

[0028] The serving cell's beam signal quality is the average of the signal quality of the best beam in the serving cell and the signal quality of the serving cell's beam currently used by the terminal device; or,

[0029] The beam signal quality of the serving cell is the signal quality of the best beam in the serving cell; or,

[0030] The serving cell's beam signal quality refers to the signal quality of the serving cell's beam currently being used by the terminal device.

[0031] Based on the method described in the third aspect, it is beneficial for terminal devices to perform cell synchronization or cell handover in a timely manner.

[0032] In one possible embodiment, a first indication information from an access network device may also be received; the first indication information indicates the value of M, or the first indication information indicates the value of X and / or the value of T.

[0033] Based on this possible embodiment, the value of M can be flexibly configured, or the value of X and / or the value of T can be flexibly configured.

[0034] In one possible embodiment, a second indication information from the access network device may also be received, which indicates the method for determining the beam signal quality of the serving cell.

[0035] Based on this possible embodiment, the method for determining the beam signal quality of the serving cell can be flexibly configured.

Figure 1 The communication system 10 shown may include, but is not limited to, access network equipment 110 and terminal equipment 120. Figure 1 The number and form of the devices are used for illustration and do not constitute a limitation on the embodiments of this application. For example, in actual applications, multiple terminal devices may be included.

It should be noted that a relay device is a terminal device capable of providing relay forwarding services to other terminal devices (including remote terminal devices).

[0063] For example, terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, mixed reality (MR) terminal devices, wireless terminal devices in industrial control, wireless terminal devices in autonomous driving, wireless terminal devices in remote medical care, wireless terminal devices in smart grids, wireless terminal devices in transportation safety, wireless terminal devices in smart cities, or wireless terminal devices in smart homes, etc.

[0064] For example, terminal devices can also be cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, terminal devices in next-generation communication systems (such as NR communication systems and 6G communication systems), or terminal devices in future evolved public land mobile networks (PLMNs), etc., without specific limitations.

[0065] In some possible implementations, the terminal device can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can be deployed on water (such as ships); or it can be deployed in the air (such as airplanes, balloons, and satellites).

[0066] In some possible implementations, the terminal device may include means for wireless communication functionality, such as a chip system, a chip, or a chip module. For example, the chip system may include a chip, and may also include other discrete devices.

[0067] In some possible implementations, the terminal device described in the embodiments of this application may be a chip, chip module, device, unit, etc., and there are no specific limitations on it.

[0068] II. Access Network Equipment

[0069] Access network equipment can be a device with transceiver capabilities, which can be used to communicate with terminal devices.

[0070] In some possible implementations, access network devices can be responsible for radio resource management (RRM), quality of service (QoS) management, data compression and encryption, and data transmission and reception on the air interface side.

[0071] In some possible implementations, access network equipment may include base stations (BS) in a communication system or equipment deployed in a radio access network (RAN) to provide wireless communication functions; that is, access network equipment may include equipment in the RAN.

[0072] For example, devices in the RAN may include evolved node B (eNB or eNodeB) in the LTE communication system, next generation evolved node B (ng-eNB) in the NR communication system, next generation node B (gNB) in the NR communication system, master node (MN) in the dual connectivity architecture, and secondary node (SN) in the dual connectivity architecture, etc., without specific restrictions.

[0073] In some possible implementations, access network devices may include devices in the core network (CN).

[0074] For example, devices in a CN may include access and mobility management function (AMF), user plane function (UPF), session management function (SMF), etc.

[0075] In some possible implementations, access network devices can also be access points (APs) in WLANs, relay stations, communication devices in future PLMN networks, communication devices in NTN networks, etc.

[0076] In some possible implementations, the access network device may include means for providing wireless communication capabilities to terminal devices, such as a chip system, a chip, or a chip module. For example, the chip system may include a chip, or it may include other discrete devices.

[0077] In some possible implementations, access network devices can communicate with Internet Protocol (IP) networks, such as the Internet, private IP networks, or other data networks.

[0078] In some possible implementations, the access network device may include a single independent node to implement the functions of the aforementioned base station, or it may include two or more independent nodes to implement the functions of the aforementioned base station. For example, the access network device includes a centralized unit (CU) and a distributed unit (DU), such as gNB-CU and gNB-DU. Furthermore, in some other embodiments of this application, the access network device may also include an active antenna unit (AAU). The CU implements some of the functions of the access network device, and the DU implements other functions. For example, the CU is responsible for handling non-real-time protocols and services, implementing the functions of the radio resource control (RRC) layer, service data adaptation protocol (SDAP) layer, and packet data convergence protocol (PDCP) layer. The DU is responsible for handling physical layer protocols and real-time services, implementing the functions of the radio link control (RLC) layer, medium access control (MAC) layer, and physical (PHY) layer. In addition, the AAU can implement some physical layer processing functions, radio frequency processing, and related functions of the active antenna. Since RRC layer information ultimately becomes PHY layer information, or is derived from PHY layer information, in this network deployment, higher-layer signaling (such as RRC signaling) can be considered to be generated by the CU and sent by the DU, or jointly sent by the DU and AAU. It is understood that access network equipment can include at least one of CU, DU, and AAU. Furthermore, the CU can be classified as RAN equipment, or it can be classified as core network equipment; there are no specific limitations on this.

[0079] In some possible implementations, the access network device can be any site in a multi-site coherent joint transmission (CJT) with the terminal device, or another site outside of that multi-site group, or other access network devices communicating with the terminal device via the network; no specific limitations are imposed. Multi-site coherent joint transmission can be joint coherent transmission by multiple sites, or different data belonging to the same Physical Downlink Shared Channel (PDSCH) being sent from different sites to the terminal device, or multiple sites being virtually merged into one site for transmission. Names with the same meaning as those specified in other standards also apply to this application; that is, this application does not limit the names of these parameters. The sites in multi-site coherent joint transmission can be remote radio heads (RRHs), transmission and reception points (TRPs), access network devices, etc., without specific limitations.

[0080] In some possible implementations, the access network device can be any one of the multiple sites performing noncoherent cooperative transmission with the terminal device, or other sites outside of the multiple sites, or other access network devices communicating with the terminal device. No specific limitations are imposed on this. The multi-site noncoherent cooperative transmission can be a joint noncoherent transmission by multiple sites, or different data belonging to the same PDSCH being sent to the terminal device from different sites, or different data belonging to the same PDSCH being sent to the terminal device from different sites. Names with the same meaning as those specified in other standards also apply to this application; that is, this application does not limit the names of these parameters. The sites in the multi-site noncoherent cooperative transmission can be RRH, TRP, access network devices, etc., without specific limitations.

[0081] In some possible implementations, the access network equipment can have mobility characteristics; for example, the access network equipment can be a mobile device. Optionally, the access network equipment can be a satellite or a balloon station. For example, the satellite can be a low-earth orbit (LEO) satellite, a medium-earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high-elliptical orbit (HEO) satellite, etc. Optionally, the access network equipment can also be a base station located on land, water, or other similar locations.

[0082] In some possible implementations, access network equipment can provide services to a cell, and terminal equipment within that cell can communicate with the access network equipment via transmission resources (such as spectrum resources). This cell can be a macro cell, small cell, metro cell, micro cell, pico cell, or femto cell, etc.

[0083] In some possible implementations, the access network device described in the embodiments of this application may be a chip, chip module, device, unit, etc., and there are no specific limitations on it.

[0084] To facilitate understanding of the embodiments of this application, the relevant names or terms involved in this application will be described below.

[0085] I. Layer 1 (L1) Measurement:

[0086] Layer 1 measurement typically refers to beam-level measurement. Layer 1 measurement can also be called beam measurement. Optionally, Layer 1 measurement includes at least one of the following: synchronization signal and PBCH block (SSB) measurement, and channel state information-reference signal (CSI-RS). The SSB can be composed of primary synchronization signals (PSS), secondary synchronization signals (SSS), and the PBCH.

[0087] II. Layer 3 (L3) Measurement

[0088] In some cases, Layer 3 measurement refers to radio resource management (RRM) measurement. In other cases, Layer 3 measurement is cell-level measurement. In some situations, RRM measurement can be understood as Layer 3 measurement.

[0089] III. LTM Switching Mechanism

[0090] In Release 18, 3GPP introduced the LTM handover mechanism, which enables terminal serving cell handover through Layer 1 / Layer 2 signaling. This helps reduce latency, overhead, and downtime during handover. Layer 1 refers to the physical layer; Layer 2 refers to one or more of the following layers: Media Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), and Service Data Adaptation Protocol (SDAP). L1 / L2 can also be understood as L1 and / or L2, meaning the LTM handover mechanism primarily involves L1 and / or L2. In the LTM handover mechanism, the access network equipment performs cell handover for the terminal equipment based on the beam measurement results (i.e., L1 measurement results) reported by the terminal equipment.

[0091] The following is combined with Figure 2 The overall process of the LTM switching mechanism is explained, such as... Figure 2 As shown:

[0092] 201. The terminal device sends a Layer 3 measurement report to the access network device in RRC connected state. Correspondingly, the access network device can receive the Layer 3 measurement report.

[0093] 202. The access network device sends an RRC reconfiguration message based on the Layer 3 measurement report. This message includes the configuration information of the candidate target cells for LTM. Correspondingly, the terminal device can receive this RRC reconfiguration message.

[0094] The RRC reconfiguration message may also include other measurement configurations.

[0095] 203. The terminal device sends an RRC reconfiguration complete message to the access network device.

[0096] Steps 201 to 203 constitute the LTM preparation stage.

[0097] 204. The terminal device sends an L1 measurement report of the candidate target cell to the access network device. Accordingly, the access network device can receive the L1 measurement report.

[0098] The access network equipment can select candidate target cells / beams of candidate target cells for downlink and / or uplink synchronization with the terminal equipment based on the L1 measurement report, and enable the terminal equipment to perform downlink and / or uplink synchronization with the candidate target cells based on the selected cell and beam.

[0099] 205a. Downlink synchronization is performed between the terminal device and the candidate target cell.

[0100] 205b. Uplink synchronization is performed between the terminal device and the candidate target cell.

[0101] In other words, in steps 205a and 205b, the terminal device can perform cell synchronization with the candidate target cell. Steps 204 to 205a and 205b constitute the early synchronization phase.

[0102] 206. The terminal device sends an L1 measurement report on the candidate target cell to the access network device. Accordingly, the access network device can receive the L1 measurement report.

[0103] 207. The access network equipment selects candidate target cells / beams for cell handover based on the L1 measurement report.

[0104] 208. Access network equipment sends cell handover commands to terminal equipment via MAC CE.

[0105] Steps 206 to 208 constitute the cell handover execution phase of LTM.

[0106] IV. Measurement Events

[0107] For example, LTM measurement events can include LTM event 2, LTM event 3, LTM event 4, and LTM event 5.

[0108] LTM Event 1: The beam signal quality of the serving cell is higher than the absolute threshold.

[0109] LTM Event 2: The beam signal quality of the serving cell is less than the absolute threshold.

[0110] LTM Event 3: The beam signal quality of the candidate target cell is higher than that of the serving cell by a relative value.

[0111] LTM Event 4: The beam signal quality of the candidate target cell is greater than the absolute threshold.

[0112] LTM Event 5: The serving cell's beam signal quality is less than absolute threshold 1, and the candidate target cell's beam signal quality is greater than another absolute threshold 2.

[0113] It can also include other measurement events based on L1 measurements.

[0114] V. Reporting Conditions for Measurement Events

[0115] When a terminal device detects a measurement event, it needs to determine whether the event meets the reporting conditions. Only if the reporting conditions are met can the terminal device report the measurement event to the access network device. For example, the reporting condition could be the duration of the measurement event (TTT, timeToTrigger), before the terminal device reports the event to the access network device.

[0116] When beam measurement results change rapidly or the terminal equipment moves quickly, the terminal equipment may fail to report measurements in a timely manner, thus preventing timely cell synchronization or handover. For example, currently, the terminal equipment only evaluates and reports measurement events based on the beam with the best signal quality in a candidate target cell. If the beam with the best signal quality meets the reporting conditions for a measurement event, a measurement report is made. If the beam with the best signal quality does not meet the reporting conditions, no measurement report is made. When beam measurement results change rapidly or the terminal equipment moves quickly, the beam with the best signal quality may not meet the reporting conditions for a measurement event. For example, suppose the reporting condition for a measurement event is that the measurement event lasts for 10 milliseconds. If the beam with the best signal quality only lasts for 5 milliseconds, then the beam with the best signal quality does not meet the reporting conditions. This results in the terminal equipment being unable to report measurements in a timely manner, thus preventing timely cell synchronization or handover.

[0117] To enable terminal devices to perform cell synchronization or cell handover in a timely manner, embodiments of this application provide a communication method and a communication device. The communication method and communication device provided in these embodiments are further described below:

[0118] Please see Figure 3 , Figure 3 This is a flowchart of a communication method provided in an embodiment of this application, which includes steps 301 to 302. Figure 3 The method shown can be executed by a terminal device and an access network device, or by a chip in the terminal device and a chip in the access network device. Figure 3 The method shown can also be implemented by other types of products, and those skilled in the art can make further extensions based on the content disclosed in the specification. Figure 3 The method shown takes terminal devices and access network devices as examples of the entities that perform the execution. Among them:

[0119] 301. The terminal equipment performs signal measurements on multiple beams of the first cell.

[0120] 302. The terminal device, in response to at least one first beam from N beams, sends a measurement report to the access network device; the N beams are N of the aforementioned plurality of beams, where N is an integer greater than 1; the first beam is the beam that satisfies the reporting conditions of the measurement event; the measurement report includes at least one of the following: the measurement event satisfied by the first beam, the identifier of the first beam, the signal quality of the first beam, and the identifier of the cell corresponding to the first beam. Accordingly, the access network device can receive the measurement report.

[0121] In other words, when at least one first beam exists among N beams, the terminal device can send a measurement report to the access network device.

[0122] In one possible embodiment, the N beams are the N beams with the best signal quality among the multiple beams of the first cell.

[0123] For example, with N = 3, the measurement event being LTM event 3, and the reporting condition for LTM event 3 being that LTM event 3 lasts for 10 milliseconds, the terminal device performs signal measurements on beams 1 to 10 of cell 1. Assume that beams 3, 5, and 7 are the three beams with the best signal quality, with beam 3 having a higher signal quality than beam 5, and beam 5 having a higher signal quality than beam 7. If at least one of beams 3, 5, and 7 satisfies the reporting condition for LTM event 3, the terminal device can send a measurement report to the access network device. For example, suppose that while beams 3 and 5 satisfy LTM event 3, they do not satisfy the reporting condition for LTM event 3, and beam 7 satisfies both LTM event 3 and its reporting condition, the terminal device can send a measurement report to the access network device. This measurement report may include at least one of the following: the measurement event satisfied by beam 7, the identifier of beam 7, the signal quality of beam 7, and the identifier of cell 1 corresponding to beam 7.

[0124] In another possible embodiment, the N beams may also be N beams of the first cell that satisfy other conditions, and this application embodiment does not limit them.

[0125] In another possible embodiment, the N beams can also be assumed to be all the beams measured in the first cell.

[0126] In one possible embodiment, the access network device may pre-send indication information to the terminal device, which may indicate one or more of the following: the first cell to be measured, the measurement event, and the reporting conditions for the measurement event. Accordingly, the terminal device may also receive this indication information from the access network device before performing signal measurements on multiple beams of the first cell. That is, the access network device may pre-configure the first cell to be measured and / or the measurement event and / or the reporting conditions for the measurement event for the terminal device. Based on this possible embodiment, the measurement configuration of the terminal device can be flexibly configured.

[0127] Optionally, the indication information may also indicate the beam to be measured in the first cell. Alternatively, the indication information may not indicate the beam to be measured in the first cell, and the beam to be measured in the first cell may be predefined by the protocol. For example, the protocol may predefine that the terminal device can measure all beams in the first cell by default.

[0128] Optionally, the indication information can also indicate the value of N, which allows for greater flexibility in the value of N. Alternatively, the value of N can be predefined by the protocol, which helps reduce indication overhead.

[0129] In another possible embodiment, the protocol may predefine one or more of the following: the first cell to be measured, the measurement event, and the reporting conditions for the measurement event. Based on this possible embodiment, indication overhead can be reduced.

[0130] Optionally, the number of first cells to be measured can be one or more. The number of measurement events can be one or more. The measurement events corresponding to different first cells can be the same or different. The reporting conditions for different measurement events can be the same or different.

[0131] In one possible embodiment, the measurement report also includes information about a second beam, which is one of the N beams that satisfies the measurement event but does not meet the reporting conditions for that measurement event.

[0132] For example, assuming that beams 3 and 5 satisfy LTM event 3, but do not meet the reporting conditions of LTM event 3, the measurement report may also include information about beams 3 and 5.

[0133] In one possible embodiment, the information of the second beam includes at least one of the following: the identifier of the second beam, the signal quality of the second beam, the identifier of the cell corresponding to the second beam, and the duration of the measurement event satisfied by the second beam.

[0134] For example, assuming beams 3 and 5 satisfy LTM event 3 but do not meet the reporting conditions for LTM event 3, the measurement report may also include information about beams 3 and 5. The information about beam 3 includes at least one of the following: the identifier of beam 3, the signal quality of beam 3, the identifier of the cell corresponding to beam 3, and the duration for which beam 3 satisfies the measurement event. The information about beam 5 includes at least one of the following: the identifier of beam 5, the signal quality of beam 5, the identifier of the cell corresponding to beam 5, and the duration for which beam 5 satisfies the measurement event.

[0135] Access network devices acquire beam information that meets the reporting conditions for a measurement event but not the event itself. This allows for a more comprehensive understanding of the beam information, which can be used to determine whether the terminal should perform cell synchronization, or select the beam for cell synchronization, or whether the terminal should perform cell handover, or select the beam for cell handover. For example, the access network device can wait for possible measurement reports from subsequent beams 3 or 5 before making a decision.

[0136] In this embodiment of the application, after receiving the measurement report, the access network device can select a cell / beam for cell synchronization based on the measurement report, so that the terminal device can perform cell synchronization based on the selected cell / beam. Alternatively, after receiving the measurement report, the access network device can select a cell / beam for cell handover based on the measurement report, so that the terminal device can perform cell handover based on the selected cell / beam.

[0137] It can be seen that, in Figure 3 In the described method, the terminal device can evaluate the reporting conditions for measurement events across multiple beams. Only when at least one beam among these beams meets the reporting conditions can the terminal device report the measurement to the access network device. Therefore, based on... Figure 3 The described method facilitates timely measurement reporting by terminal devices, thereby enabling timely cell synchronization or cell handover.

[0138] To enable terminal devices to perform cell synchronization or cell handover in a timely manner, embodiments of this application provide a communication method and a communication device. The communication method and communication device provided in these embodiments are further described below:

[0139] Please see Figure 4 , Figure 4 This is a flowchart of a communication method provided in an embodiment of this application, which includes step 401. Figure 4 The method shown can be executed by a terminal device, or by a chip within the terminal device. Figure 4 The method shown can also be implemented by other types of products, and those skilled in the art can make further extensions based on the content disclosed in the specification. Figure 4 The method shown is implemented using a terminal device as an example. Wherein:

[0140] 401. The terminal device determines whether the measurement event is satisfied based on the beam signal quality of the serving cell.

[0141] The beam signal quality of the serving cell can be determined using any of the following methods:

[0142] 1) The beam signal quality of the serving cell is the average of the signal quality of the M best beams of the serving cell, where M is an integer greater than 1.

[0143] For example, taking M as 3, the terminal device measures the signal quality of 10 beams in the serving cell. Among them, beams 1 to 3 are the three beams with the best signal quality in the serving cell. The beam signal quality of the serving cell is the average of the signal quality of beams 1 to 3.

[0144] By using the average signal quality of the M best beams of the serving cell as the beam signal quality of the serving cell, the terminal equipment can use multiple beams as input for measurement event evaluation, which helps to avoid problems such as failure to perform cell synchronization or cell handover in a timely manner due to beam signal jitter.

[0145] 2) The beam signal quality of the serving cell is the average of the signal quality of all beams in the serving cell.

[0146] For example, the terminal device measures the signal quality of 10 beams in the serving cell. The beam signal quality of the serving cell is the average of the signal quality of beams 1 to 10.

[0147] By using the average signal quality of all beams in the serving cell as the serving cell's beam signal quality, the terminal device can use multiple beams as input for measurement event evaluation, which helps avoid problems caused by beam signal jitter that prevent timely cell synchronization or cell handover.

[0148] 3) The beam signal quality of the serving cell is the average of the signal quality of the X best first beams of the serving cell, where X is an integer greater than or equal to 1, and the first beam is the beam whose signal quality of the serving cell exceeds the threshold value T.

[0149] For example, taking X as 3, the terminal device measured the signal quality of 10 beams in the serving cell. The signal quality of beams 1 through 4 exceeded the threshold T. The signal quality of beam 1 was greater than that of beam 2, beam 2 was greater than that of beam 3, and beam 3 was greater than that of beam 4. The signal quality of the serving cell beams was the average of the signal quality of beams 1 through 3.

[0150] By using the average signal quality of the X best first beams of the serving cell as the beam signal quality of the serving cell, the terminal equipment can use multiple beams as input for measurement event evaluation, which helps to avoid problems such as failure to perform cell synchronization or cell handover in a timely manner due to beam signal jitter.

[0151] 4) The signal quality of the serving cell is the average of the signal quality of all first beams in the serving cell. The number of first beams is less than X. The first beam is the beam whose signal quality of the serving cell exceeds the threshold value T.

[0152] For example, taking X as 3. The terminal device measured the signal quality of 10 beams in the serving cell. The signal quality of beams 1 to 2 exceeded the threshold T. The signal quality of the serving cell beams is the average of the signal quality of beam 1 and beam 2.

[0153] By using the average signal quality of all first beams of the serving cell as the beam signal quality of the serving cell, it is beneficial to avoid problems such as the inability to perform timely cell synchronization or cell handover due to beam signal jitter.

[0154] In another possible embodiment, the beam signal quality of the serving cell is the average of the signal quality of all first beams of the serving cell, regardless of whether the number of first beam signal qualities is less than X.

[0155] 5) The beam signal quality of the serving cell is the average of the signal quality of the best beam of the serving cell and the signal quality of the beam of the serving cell currently used by the terminal device.

[0156] By using the average signal quality of the best beam of the serving cell and the signal quality of the serving cell beam currently used by the terminal device as the serving cell beam signal quality, the terminal device can use multiple beams as input for measurement event evaluation, which helps to avoid problems such as failure to perform cell synchronization or cell handover in a timely manner due to beam signal jitter.

[0157] 6) The beam signal quality of the serving cell is the signal quality of the best beam of the serving cell.

[0158] By using the signal quality of the best beam of the serving cell as the signal quality of the serving cell, it is beneficial to carry out timely measurement reporting, thereby enabling timely cell synchronization or cell handover.

[0159] 7) The beam signal quality of the serving cell is the signal quality of the beam of the serving cell currently used by the terminal device.

[0160] By using the signal quality of the serving cell's beam currently used by the terminal device as the serving cell's beam signal quality, it is beneficial to perform timely measurement reporting, thereby enabling timely cell synchronization or cell handover.

[0161] In one possible embodiment, the access network device may send first indication information to the terminal device; the first indication information indicates the value of M, or the first indication information indicates the value of X and / or the value of T. Accordingly, the terminal device may receive the first indication information.

[0162] Based on this possible embodiment, the value of M can be flexibly configured, or the value of X and / or the value of T can be flexibly configured.

[0163] In another possible embodiment, the value of M can also be predefined by the protocol. Based on this possible embodiment, it is advantageous to reduce indication overhead.

[0164] In another possible embodiment, the values ​​of X and / or T can also be predefined by the protocol. This possible embodiment is advantageous in reducing indication overhead.

[0165] In one possible embodiment, the access network device may send second indication information to the terminal device, the second indication information indicating the method for determining the beam signal quality of the serving cell. Accordingly, the terminal device may receive the second indication information. Based on this possible embodiment, the terminal device can determine the beam signal quality of the serving cell more flexibly.

[0166] For example, if the second indication information indicates that the method for determining the beam signal quality of the serving cell is Method 1 as described above, then the beam signal quality of the serving cell is the average of the signal quality of the M best beams of the serving cell. If the second indication information indicates that the method for determining the beam signal quality of the serving cell is Method 3 as described above, then the beam signal quality of the serving cell is the average of the signal quality of the X best first beams of the serving cell. If the second indication information indicates that the method for determining the beam signal quality of the serving cell is Method 5 as described above, then the beam signal quality of the serving cell is the average of the signal quality of the best beam of the serving cell and the signal quality of the beam of the serving cell currently used by the terminal device.

[0167] In another possible embodiment, the method by which the terminal device determines the beam signal quality of the serving cell can also be predefined by the protocol. Based on this possible embodiment, it is advantageous to reduce indication overhead.

[0168] In one possible embodiment, the measurement event can be one or more of the following: LTM event 1, LTM event 2, LTM event 3, and LTM event 5. The measurement event can be configured by the access network device or predefined by the protocol, and this application embodiment does not limit it.

[0169] It can be seen that, in Figure 4 The described method facilitates timely cell synchronization or cell handover for terminal devices.
