Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless communication, and in particular to a communication method, a chip, an apparatus, a storage medium and a product. BACKGROUND

[0002] In a L1 / L2 triggered mobility (LTM) procedure, there is an interaction of a third layer measurement (L3 measurement) report and control signaling between a terminal device and a base station. When the LTM is started, a gNodeB central unit (gNB-CU) initiates an LTM configuration decision, and sends a radio resource control (RRC) reconfiguration message to a gNodeB distributed unit (gNB-DU), and then the gNB-DU sends the RRC reconfiguration message to the terminal device. After the terminal device completes the measurement, the terminal device sends an L1 measurement report to the base station, and the network makes an LTM cell handover decision.

[0003] In order to provide a basis for cell handover, one possible way is to continuously perform channel state information reference signal (CSI-RS) measurement on all target cells, but this way has a large number of measurements of the terminal device and a large signaling overhead. Therefore, how to reduce the signaling overhead of CSI-RS measurement on the target cell has become a technical problem to be solved at present. SUMMARY

[0004] The present application provides a communication method, a chip, an apparatus, a storage medium and a product, aiming to solve the problem of how to reduce the signaling overhead of CSI-RS measurement on the target cell.

[0005] In order to achieve the above-mentioned purpose, the present application provides the following technical solutions: The first aspect of the present application provides a communication method, which can be executed by a terminal device, or can be executed by a component (such as a circuit, a chip or a chip system, etc.) configured in the terminal device, and can also be realized by a logic module or software which can realize all or part of the functions of the terminal device. For example, the method is applied to a first terminal device, and the present application does not limit this. Hereinafter, the terminal device is taken as an example for description. The method comprises: receiving first information, the first information being used for the terminal device to obtain a priority of a candidate cell; generate a measurement report at a measurement occasion corresponding to the priority of the candidate cell, the priority of the candidate cell being positively related to a frequency of generating the measurement report; transmit second information, the second information being used for indicating the measurement report.

[0006] In the above scheme, by receiving first information used for indicating the terminal device to acquire the priority of the candidate cell, the terminal device determines the priority of each candidate cell and generates a measurement report according to the priority of each cell. Since the priority is positively related to the frequency of generating the measurement report in the present application, the candidate cell with a higher priority has a higher measurement frequency, and the candidate cell with a lower priority has a lower measurement frequency, thereby reducing the number of measurements of the terminal device on the candidate cell with a lower priority, and reducing the signaling overhead of CSI-RS measurement on the target cell.

[0007] In some possible implementation manners, the first information is used for carrying the priority of the candidate cell.

[0008] In the above scheme, the first information directly carries the priority of the candidate cell, so that the terminal device can quickly determine the priority of each candidate cell without calculation, In some possible implementation manners, the first information is a radio resource control (RRC) reconfiguration message, and the RRC reconfiguration message includes a first field used for carrying the priority of the candidate cell.

[0009] In the above scheme, the first field is set in the RRC, so that the RRC can carry the priority of the candidate cell, and the terminal device can determine the priority of the candidate cell after receiving the RRC.

[0010] In some possible implementation manners, the priority of the candidate cell is determined based on a signal quality of the candidate cell.

[0011] In the above scheme, the priority of the candidate cell is divided based on the signal quality, so that the candidate cell with a higher signal quality has a higher priority, and it is ensured that the candidate cell after switching is a cell with a higher signal quality.

[0012] In some possible implementation manners, the first information is used for carrying one or more of the following: information indicating that the priority of the candidate cell is a first priority, the candidate cell with the first priority having a signal quality level higher than a signal quality level of a current cell; information indicating that the priority of the candidate cell is a second priority, the candidate cell with the second priority having a signal quality level same as a signal quality level of a current cell; information indicating that the priority of the candidate cell is a third priority, the signal quality level of the candidate cell of the third priority being lower than the signal quality level of the current cell.

[0013] In some possible implementation manners, the signal quality of the candidate cell of the first priority is higher than the signal quality of the current cell for a first time period.

[0014] In the foregoing solution, since the signal quality of the first candidate cell needs to be higher than the signal quality of the current cell and the duration needs to be at least longer than the first time period, it is ensured that the candidate cell of the first priority is a cell with stable and higher signal quality.

[0015] In some possible implementation manners, the signal quality of the candidate cell of the second priority is within a signal quality range for a second time period, the signal quality range being a difference between the signal quality of the current cell and a second threshold and being less than or equal to a sum of the signal quality of the current cell and a third threshold.

[0016] In the foregoing solution, since the signal quality of the first candidate cell needs to be within the signal quality range and the duration needs to be at least longer than the second time period, it is ensured that the determined candidate cell of the second priority is a cell with stable signal quality within the signal quality range for a long time, thereby guaranteeing the accuracy of the determined priority of the candidate cell and avoiding that the network device is switched to an inaccurate cell and needs to frequently switch cells due to inaccurate determination of the priority of the cell.

[0017] In some possible implementation manners, the signal quality of the candidate cell of the third priority is lower than the signal quality of the current cell for a third time period.

[0018] In the foregoing solution, since the signal quality of the first candidate cell needs to be lower than the signal quality of the current cell and the duration needs to be at least longer than the third time period, it is ensured that the determined candidate cell of the third priority is a cell with signal quality lower than the signal quality of the current cell for a long time, thereby guaranteeing the accuracy of the determined priority of the candidate cell and avoiding that the network device is switched to an inaccurate cell and needs to frequently switch cells due to inaccurate determination of the priority of the cell.

[0019] In some possible implementation manners, the method further includes: receiving a downlink control information (DCI), the DCI being used to activate the terminal device to measure the candidate cell of the third priority.

[0020] In the above scheme, the measurement frequency of the third priority candidate cell is reduced by triggering the measurement of the third priority candidate cell only after receiving the DCI message, thereby saving signaling overhead.

[0021] In some possible implementation manners, the method further includes: receiving a medium access control control element (MAC CE), the MAC CE being used to activate the terminal device to perform the measurement on the candidate cell of the second priority.

[0022] In the above scheme, the measurement frequency of the second priority candidate cell is reduced by triggering the periodic measurement of the second priority candidate cell only after receiving the MAC CE, thereby saving signaling overhead and making the measurement frequency of the second priority candidate cell controllable.

[0023] In some possible implementation manners, the first information is specifically used to carry measurement configuration information, and the measurement configuration information is used to determine the priority of the candidate cell.

[0024] In some possible implementation manners, the measurement configuration information includes priority division parameters and measurement parameters, the priority division parameters and the measurement parameters are used to determine the priority of the candidate cell, the candidate cell includes a current cell, the priority division parameters include at least one of a low reference signal receiving power threshold and a high reference signal receiving power threshold, and the measurement parameters include at least one of a priority switching hysteresis, a number of candidate cells of a fourth priority allowed to exist simultaneously, a measurement period of the candidate cell of the fourth priority, a measurement period of a candidate cell of a fifth priority, a reporting period of the candidate cell of the fourth priority, and a reporting period of the candidate cell of the fifth priority, the priority of the fourth priority being higher than the priority of the fifth priority.

[0025] In the above scheme, the terminal device determines the priority of the candidate cell based on the priority division parameters and the measurement parameters, so as to divide the priorities of the candidate cells based on the received power, to make the candidate cell with higher signal receiving power have higher priority, and to ensure that the candidate cell after switching is a cell with higher receiving power.

[0026] In some possible implementation manners, the first information is an RRC reconfiguration message, and the RRC reconfiguration message includes a second field used to carry the priority division parameters and the measurement parameters.

[0027] In some possible implementation manners, the priority of the candidate cell is determined based on the priority division parameters, the measurement parameters, and a reference signal receiving power.

[0028] In some possible implementation manners, the priority of the candidate cell includes a fourth priority, a reference signal received power of the candidate cell of the fourth priority is greater than or equal to the low reference signal received power threshold, a reference signal received power in a measurement period of m consecutive candidate cells of the fourth priority is greater than a sum of the high reference signal received power threshold and the priority switching hysteresis, and the reference signal received power is greater than or equal to a reference signal received power of an n th cell in a reference signal received power ranking, the reference signal received power ranking is a ranking of the candidate cells from high to low in reference signal received power, the n is a number of the candidate cells of the fourth priority allowed to exist simultaneously, and the m is an integer greater than or equal to 1.

[0029] In the foregoing solution, the number of the candidate cells of the fourth priority allowed to exist simultaneously is set, so that the number of the candidate cells of the fourth priority allowed to exist simultaneously is reduced, thereby reducing the total overhead of the terminal device for the candidate cells of the fourth priority, to avoid the terminal device from frequently measuring a large number of candidate cells due to the existence of a large number of candidate cells of the fourth priority.

[0030] In some possible implementation manners, the priority of the candidate cell includes a fifth priority, a reference signal received power of the candidate cell of the fifth priority is greater than or equal to the low reference signal received power threshold and less than a difference between the high reference signal received power threshold and the priority switching hysteresis. Alternatively, a reference signal received power of the candidate cell of the fifth priority is greater than or equal to the low reference signal received power threshold, a reference signal received power in a measurement period of m consecutive candidate cells of the fourth priority is greater than a sum of the high reference signal received power threshold and the priority switching hysteresis, and the reference signal received power is less than a reference signal received power of an n th cell in a reference signal received power ranking, the reference signal received power ranking is a ranking of the candidate cells from high to low in reference signal received power, the n is a number of the candidate cells of the fourth priority allowed to exist simultaneously, and the m is an integer greater than or equal to 1.

[0031] In some possible implementation manners, the second information is used to carry the priority of the current cell.

[0032] A second aspect of the present application provides a communication method, which can be executed by a network device, or can be executed by a component (such as a circuit, a core network unit, a chip or a chip system, etc.) configured in the network device, can also be implemented by a logic module or software that can implement all or part of the network device functions. The present application does not make any limitation in this regard. Hereinafter, the network device is taken as an example for description. The method comprises: The first information is transmitted, and the first information is used to indicate that the terminal device acquires the priority of the candidate cell; the priority of the candidate cell is positively correlated with the frequency of generating a measurement report by the terminal device. The second information is received, and the second information includes the measurement report.

[0033] In the above scheme, by transmitting the first information for indicating the terminal device to acquire the priority of the candidate cell, the terminal device determines the priority of each candidate cell, and generates a measurement report according to the priority of each cell. Since the priority is positively correlated with the frequency of generating a measurement report in the present application, the candidate cell with high priority has a higher measurement frequency, and the candidate cell with low priority has a lower measurement frequency, thereby reducing the number of measurements of the terminal device on the candidate cell with low priority, and reducing the signaling overhead of CSI-RS measurement on the target cell.

[0039] In some possible implementation manners, the signal quality of the candidate cell of the second priority is in a signal quality range for a second time period, the signal quality range being greater than a difference between the signal quality of the current cell and a second threshold value and less than or equal to a sum of the signal quality of the current cell and a third threshold value.

[0040] In some possible implementation manners, the signal quality of the candidate cell of the third priority is lower than the signal quality of the current cell for a third time period.

The network device can be a base station (including a functional unit of the base station or a combination of functional units of the base station) or a core network unit in general.

[0064] ​In the embodiments provided in the present application, the terminal can be various forms, for example, a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a vehicle-mounted terminal device, a wireless terminal in self driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, a wearable terminal device, and the like. The terminal can also be referred to as a terminal device, a user equipment (UE), an access terminal device, a vehicle-mounted terminal, an industrial control terminal, a UE unit, a UE station, a mobile station, a mobile station, a remote station, a remote terminal device, a mobile device, a UE terminal device, a terminal device, a wireless communication device, a UE agent, or a UE apparatus, and the like. The terminal can also be a fixed terminal or a mobile terminal.

[0065] LTM is a 5G mobility management optimization mechanism. Specifically, a gNB receives an L1 or L3 measurement report from a UE, and based on the L1 or L3 measurement report, the gNB can change the serving cell of the UE through a cell handover command sent by a MAC CE. The gNB provides an LTM candidate configuration to the UE through RRC signaling. After the gNB issues an RRC reconfiguration, the UE performs L1 measurement on the configured LTM candidate cell and sends an L1 measurement report to the gNB. Subsequently, the gNB decides to perform cell handover, sends an LTM cell handover command to trigger cell handover, and the UE switches to the target cell according to the cell handover command.

[0066] In order to provide a basis for cell handover, one possible way is to continuously perform channel state information reference signal (CSI-RS) measurement on all target cells. However, this way requires the terminal device to perform a large number of measurements, and the signaling overhead is large. Therefore, how to reduce the signaling overhead of CSI-RS measurement on the target cell has become a technical problem to be solved at present.

[0067] In order to make the technical solutions of the present application clearer and easier to understand, the following describes a communication method, device, chip, system, storage medium and product provided by the embodiments of the present application with reference to the accompanying drawings.

[0068] Referring to Figure 2 A flowchart of a communication method is shown, and the method comprises: S201: The network device sends first information. Correspondingly, the terminal device receives the first information, and the first information is used by the terminal device to obtain the priority of the candidate cell.

[0069] The first information at least comprises information that enables the terminal device to determine the priority of each candidate cell, for example, the first information can directly carry the priority of each candidate cell, or indicate the manner in which the terminal device determines the priority of each candidate cell, or indicate a plurality of parameters, so that the terminal device determines the priority of each candidate cell based on the locally stored priority determination method and parameters.

[0070] S202: The terminal device generates a measurement report at a measurement occasion corresponding to the priority of the candidate cell, and the priority of the candidate cell is positively correlated with the frequency at which the terminal device generates the measurement report.

[0071] In this embodiment, the priority is used to determine the frequency at which the measurement report is generated, and different measurement occasions are set for candidate cells of different priorities, so that the frequency at which the measurement report is generated for candidate cells of different priorities is different. For example, after the priority of each candidate cell is determined, the candidate cells are arranged in order of priority from high to low, and the measurement occasions are set for the arranged candidate cells in order of generation frequency from high to low, wherein candidate cells of different priorities have different measurement occasions, and candidate cells of the same priority have the same measurement occasion, so that the higher the priority of the candidate cell, the higher the frequency at which the measurement report is generated. Candidate cells of the same priority can also correspond to different measurement occasions with the same generation frequency, so that candidate cells of the same priority can be measured at different measurement times, avoiding excessive resource occupation caused by the terminal device needing to measure multiple candidate cells at the same time.

[0072] There is a one-to-one correspondence between the measurement occasion and the generation frequency of the measurement report, and the measurement occasion is the occasion for generating the measurement report. The measurement occasion can be a specific period, or a parameter that can change the generation frequency of the measurement report, such as a trigger condition for generating the measurement report.

[0073] It should be noted that the correspondence between the measurement occasion and the priority can be generated by the terminal device or by the network device. For example, the correspondence between the measurement occasion and the priority can be stored locally in the terminal device, or configured by the network device, or in the case where the terminal device receives the correspondence between the measurement occasion and the priority configured by the network device, the measurement occasion is set for the candidate cell according to the correspondence between the measurement occasion and the priority configured by the network device, and in the case where the terminal device does not receive the correspondence between the measurement occasion and the priority configured by the network device, the measurement occasion is set for the candidate cell based on the correspondence between the measurement occasion and the priority stored locally in the terminal device.

[0074] S203: The terminal device sends second information, and the second information includes a measurement report. Correspondingly, the network device receives the second information.

[0075] After the measurement report is generated, the terminal device carries the measurement report in the second information and sends the second information to the network device, so that the network device receives the measurement report of the candidate cell and obtains the information required by the network device. The measurement report at least includes information required by the network device for the terminal device to perform measurement.

[0076] For ease of understanding, the following describes subsequent examples with the first information directly carrying the priority of each candidate cell: Figure 3 For another communication method disclosed in the embodiments of the present application, Figure 3 includes the following steps: S301: The network device divides the priority of the candidate cell.

[0077] The network device sets the priority of the candidate cell based on the signal quality of the candidate cell, that is, the priority of the candidate cell is determined based on the signal quality of the candidate cell. The network device can obtain the signal quality of each candidate cell through third layer measurement. The candidate cell can include the current cell.

[0078] In an optional embodiment, the network device divides the candidate cell into a plurality of priorities based on the signal quality of each candidate cell. The number of priorities can be set based on actual needs, for example, the signal quality is divided into five intervals, and each interval corresponds to one priority. The higher the interval of the signal quality, the higher the priority corresponding to the interval. For ease of understanding, the following examples are given: If the candidate cells include candidate cell A, candidate cell B, candidate cell C and candidate cell D, the network device divides the signal quality into three intervals, the signal quality of the first interval a is the highest, the signal quality of the second interval b is between the first interval a and the third interval c, and the signal quality of the third interval c is the lowest. If the signal quality of the candidate cell A is in the first interval a, the signal quality of the candidate cell C and the candidate cell D is in the second interval b, and the signal quality of the candidate cell B is in the third interval c, the priority of the candidate cell A is higher than that of the candidate cell C and the candidate cell D, the candidate cell C and the candidate cell D have the same priority, and the priority of the candidate cell C and the candidate cell D is higher than that of the candidate cell B.

[0079] S302: The network device sends first information, and the first information is used for the terminal device to acquire the priority of the candidate cell. Correspondingly, the terminal device receives the first information.

[0080] The priority of the candidate cell is carried in the first information, so that the terminal device can directly determine the priority of each candidate cell based on the content in the first information after receiving the first information. The first information is information sent by the network device to the terminal device or information broadcasted externally. For example, the first information can be an RRC reconfiguration message, the RRC reconfiguration message includes a first field, the first field is used to carry the priority of the candidate cell, and the first field is a newly added field in the RRC reconfiguration message. The newly added field can be a handover cell priority (candidate cell priority) field.

[0081] The network device can divide the priority of the candidate cell based on the signal quality condition and the duration requirement, and carry the divided priority of the candidate cell in the first information.

[0082] In an optional embodiment, if the first information carries information indicating that the priority of the candidate cell is a first priority, it means that the signal quality level of the candidate cell with the first priority is higher than that of the current cell. The terminal device determines the candidate cell with the first priority based on the indication of the first information after receiving the first information.

[0083] Specifically, the signal quality condition can be that the signal quality level of the candidate cell is higher than the signal quality level of the current cell, and the duration requirement can be that the duration exceeds the first time period. When the signal quality of the candidate cell is greater than the signal quality of the current cell and the duration exceeds the first time period, it is determined that the signal quality level of the candidate cell is higher than the signal quality level of the current cell. This embodiment can determine whether the signal quality of the candidate cell is greater than the signal quality of the current cell by using the layer 3 filtered measurement result Mn of the candidate cell, the layer 3 filtered measurement result Ms of the current cell, the hysteresis parameter Hys, and the highest offset OffHigh. The hysteresis parameter is a parameter describing the relationship between the response speed and the input signal change speed. If Mn-Hys>Ms+OffHigh, the signal quality of the candidate cell is greater than the signal quality of the current cell. The first time period can be set based on actual needs. The longer the time period, the more stable the signal quality of the candidate cell selected. In this embodiment, the first time period is 40 milliseconds, that is, Mn-Hys>Ms+OffHigh, and the candidate cell with a duration of more than 40 milliseconds is the candidate cell of the first priority.

[0084] Further, when the first information indicates that the priority of the candidate cell is the first priority, the first information further carries periodic CSI-RS resources and a reporting period of the candidate cell of the first priority. One CSI-RS resource index is associated with one candidate cell index.

[0085] In an optional embodiment, if the first information carries information indicating that the priority of the candidate cell is the second priority, it means that the signal quality level of the candidate cell of the second priority is the same as the signal quality level of the current cell. The terminal device determines the candidate cell with the second priority based on the indication of the first information after receiving the first information.

[0086] Specifically, the signal quality condition can be that the signal quality of the candidate cell belongs to a signal quality range, and the duration requirement can be that the duration exceeds a second time period. When the signal quality of the candidate cell of the second priority belongs to the signal quality range and the duration exceeds the second time period, it is determined that the signal quality grade of the candidate cell is equal to the signal quality grade of the current cell, the signal quality range is greater than the difference between the signal quality of the current cell and a second threshold value, and is less than or equal to the sum of the signal quality of the current cell and a third threshold value. The embodiment can determine whether the signal quality of the candidate cell belongs to the signal quality range by using the layer 3 filtered measurement result Mn of the candidate cell, the layer 3 filtered measurement result Ms of the current cell, the hysteresis parameter Hys, the minimum offset value OffMin and the maximum offset value OffHigh. If Ms-OffMin-Hys < Mn ≤ Ms+OffHigh-Hys, the signal quality of the candidate cell belongs to the signal quality range. The second time period in the embodiment is 80 milliseconds, that is, Ms-OffMin-Hys < Mn ≤ Ms+OffHigh-Hys, and the candidate cell with a duration exceeding 80 milliseconds is the candidate cell of the second priority. By introducing the hysteresis parameter in the comparison, the influence of the instantaneous fluctuation of the signal quality on the comparison result is avoided, and the accuracy of the comparison result is ensured.

[0087] Further, when the first information indicates that the priority of the candidate cell is the second priority, the first information further carries a semi-persistent CSI-RS resource and a reporting period of the candidate cell of the second priority, and the semi-persistent CSI-RS resource is activated by a medium access control control element (MAC CE). The method further includes that the terminal device receives the MAC CE, and the MAC CE is used to activate the terminal device to measure the candidate cell of the second priority.

[0088] In an optional embodiment, if the first information is used to carry information indicating that the priority of the candidate cell is the third priority, it indicates that the signal quality grade of the candidate cell of the third priority is lower than the signal quality grade of the current cell, and the terminal device determines the candidate cell of the third priority based on the indication of the first information after receiving the first information.

[0089] Specifically, the signal quality condition can be that the signal quality level of the candidate cell is lower than the signal quality level of the current cell, and the duration requirement can be that the duration exceeds a third time period. When the signal quality of the candidate cell of the third priority is lower than the signal quality of the current cell, and the duration exceeds the third time period, it is determined that the signal quality level of the candidate cell is lower than the signal quality level of the current cell. In this embodiment, whether the signal quality of the candidate cell is lower than the signal quality of the current cell can be determined by the layer 3 filtered measurement result Mn of the candidate cell, the layer 3 filtered measurement result Ms of the current cell, the hysteresis parameter Hys and the minimum offset value OffMin. If Mn+Hys≤Ms-OffMin, the signal quality of the candidate cell is lower than the signal quality of the current cell. In this embodiment, the third time period is 160 milliseconds, that is, Mn+Hys≤Ms-OffMin, and the candidate cell with a duration exceeding 160 milliseconds is the cell of the third priority.

[0090] Further, when the first information indicates that the priority of the candidate cell is the second priority, the first information further carries a semi-persistent CSI-RS resource, and the semi-persistent CSI-RS resource is activated by downlink control information (DCI). The method further includes: receiving, by the terminal device, the DCI, and the DCI is used to activate the terminal device to measure the candidate cell of the third priority.

[0091] It should be noted that, in addition to carrying information for indicating a plurality of candidate cells of a certain priority, the first information in the present application can also simultaneously carry information for indicating a plurality of candidate cells of different priorities.

[0092] For example, when the network device determines that the candidate cells include the candidate cell of the first priority and the candidate cell of the second priority, the first information is used to carry information indicating the candidate cell of the second priority and information indicating the candidate cell of the first priority.

[0093] When the network device determines that the candidate cells include the candidate cell of the second priority and the candidate cell of the third priority, the first information is used to carry information indicating the candidate cell of the second priority and information indicating the candidate cell of the third priority.

[0094] When the network device determines that the candidate cells include the candidate cell of the first priority, the candidate cell of the second priority and the candidate cell of the third priority, the first information is used to carry information indicating the candidate cell of the first priority, information indicating the candidate cell of the second priority and information indicating the candidate cell of the third priority. The priorities are sequentially ordered from high to low as the first priority, the second priority and the third priority.

[0095] The duration in the present application can be a continuous duration, or a sum of all time periods meeting the signal quality condition within the signal quality measurement time. For example, when the signal quality measurement time is shorter than the first time, the signal quality measurement time is too short, and all time periods meeting the signal quality condition within the signal quality measurement time are accumulated as the duration to determine whether the duration requirement is met. When the signal quality measurement time is higher than the first time, the signal quality measurement time is long enough to reflect the signal quality of the candidate cell in a normal working environment, and at this time, it can be determined whether the longest time period meeting the signal quality condition within the signal quality measurement time meets the duration requirement to determine whether the duration requirement is met.

[0096] S303: The terminal device generates a measurement report at a measurement occasion corresponding to the priority of the candidate cell, the priority being used to determine the frequency of generating the measurement report, and the priority of the candidate cell being positively correlated with the frequency of generating the measurement report.

[0097] Since the higher the priority of the candidate cell, the higher the probability of becoming a handover target, to reduce the number of measurements and reporting frequencies, the number of measurements and reporting frequencies of the candidate cell with a lower priority can be reduced. Taking the above candidate cells including the candidate cell of the first priority, the candidate cell of the second priority, and the candidate cell of the third priority as an example, since the candidate cell of the first priority has a higher probability of becoming a handover target, the network device needs to know the signal quality of the candidate cell of the first priority in real time, and therefore the terminal device needs to periodically report the candidate cell of the first priority to achieve high-frequency and stable monitoring. The handover target is the candidate cell switched to by the network device based on the content in the second information.

[0098] Since the signal quality of the candidate cell of the second priority is similar to that of the current cell and is a potential handover target, the measurement frequency can be appropriately reduced. Since the signal quality of the candidate cell of the third priority is not as good as that of the current cell and the probability of becoming a handover target is low, the lowest measurement frequency can be used, or measurement and reporting can be omitted by default.

[0099] Specifically, since the candidate cell of the first priority needs to be measured frequently, the measurement occasion corresponding to the candidate cell of the first priority is to activate the CSI-RS resource directly after receiving the RRC reconfiguration message, and periodic measurement is performed without additional signaling, and reporting is performed according to the reporting period corresponding to the candidate cell of the first priority.

[0100] The candidate cell of the second priority does not need to start measurement at the same time as the candidate cell of the first priority, and the candidate cell of the second priority can perform measurement and reporting after the candidate cell of the first priority starts measurement to reduce the measurement frequency, so that the network device can determine the MAC CE delivery time based on the redundancy of the candidate cell of the first priority. The measurement time of the candidate cell of the second priority is when the terminal device receives the MAC CE.

[0101] For example, the network device sends the MAC CE when the number of candidate cells of the first priority is less than or equal to the fifth threshold. When the number of candidate cells of the first priority is greater than the fifth threshold, the network device sends the MAC CE after waiting for a reporting period of t candidate cells of the first priority, where t is an integer greater than or equal to 1, and t is 2 in this embodiment.

[0102] Specifically, when the number of candidate cells of the first priority is less than or equal to the fifth threshold, because the switching redundancy is insufficient, the network device can immediately deliver the MAC CE to activate the CSI-RS resource of the candidate cell of the second priority after the RRC configuration is completed.

[0103] When the number of candidate cells of the first priority is greater than the fifth threshold, because the switching redundancy is sufficient, the network device waits for a reporting period corresponding to t candidate cells of the first priority after the RRC configuration is completed, and then delivers the MAC CE to activate the CSI-RS resource of the candidate cell of the second priority. After the terminal device receives the MAC CE at any time, the terminal device performs measurement on the candidate cell of the second priority, and reports according to the reporting period corresponding to the candidate cell of the second priority. In this embodiment, t is 2, and the fifth threshold is 1.

[0104] The candidate cell of the third priority does not perform measurement by default, and to avoid the case where neither the candidate cell of the first priority nor the candidate cell of the second priority is available, the semi-persistent CSI-RS resource corresponding to the third priority can be temporarily triggered by the measurement request bit of the DCI 0_1. The network device sends the DCI when neither the candidate cell of the first priority nor the candidate cell of the second priority is available. That is, the measurement time of the candidate cell of the third priority is when the terminal device receives the DCI, and after generating the measurement report of the candidate cell of the third priority, the terminal device immediately reports the measurement report of the candidate cell of the third priority through the second information.

[0105] S304: The terminal device sends the second information, and the second information is used to indicate the measurement report. Correspondingly, the network device receives the second information.

[0106] The measurement report should include at least the parameters that the network device requires the terminal device to provide, such as channel status data. The second piece of information is the information that the terminal device feeds back to the network device. For example, when reporting measurement reports for candidate cells with the highest priority, the second information may specifically be the physical uplink control channel (PUCCH) or the physical uplink shared channel (PUSCH).

[0107] When reporting measurement reports for candidate cells with the second priority, the second piece of information can specifically be PUCCH.

[0108] When reporting measurement reports for candidate cells of the third priority, the second piece of information can specifically be PUSCH.

[0109] For ease of understanding, the following explanation will use the example of a terminal device storing multiple parameters in the first information field, along with priority allocation rules pre-agreed with the network device, to determine the priority of each candidate cell based on the locally stored priority determination method and parameters. Figure 4 This is yet another communication method disclosed in the embodiments of this application. Figure 4 The process includes the following steps: S401: The network device sends first information, which is used by the terminal device to obtain the priority of the candidate cell. Correspondingly, the terminal device receives the first information.

[0110] The first piece of information specifically carries measurement configuration information, which is used to determine the priority of candidate cells. The measurement configuration information may include priority allocation parameters and measurement parameters, which are used to determine the priority of candidate cells, including the current cell.

[0111] Priority parameters include at least one of the low reference signal received power threshold (low rsrp thresh) and the high reference signal received power threshold (high rsrp thresh).

[0112] The priority of candidate cells includes fourth priority and fifth priority. The fourth priority has a higher priority than the fifth priority. In this embodiment, the fourth priority can also be referred to as high priority, and the fifth priority can also be referred to as low priority.

[0113] The measurement parameters include at least one of a priority switching hysteresis (prio hysteresis), a number of candidate cells of a fourth priority allowed to exist simultaneously (max high prio num), a measurement period of the candidate cells of the fourth priority (high prio meas period), a measurement period of candidate cells of a fifth priority (low prio meas period), a reporting period of the candidate cells of the fourth priority (high prio report period), and a reporting period of the candidate cells of the fifth priority (low prio report period).

[0114] The first information is an RRC reconfiguration message, and the RRC reconfiguration message includes a second field used to carry the priority division parameter and the measurement parameter. The second field is a newly added field in the RRC reconfiguration message.

[0115] S402: The terminal device determines the priority of the candidate cell based on the first information.

[0116] After receiving the first information, the terminal device immediately determines the priority of the candidate cell. The priority of the candidate cell is determined based on the priority division parameter, the measurement parameter, and the reference signal received power. The reference signal received power is specifically a layer 1 reference signal received power (L1-RSRP), and the terminal device divides the priority of the candidate cell by using the L1-RSRP, the priority division rule, and the priority division parameter and the measurement parameter carried in the first information sent by the network device.

[0117] Specifically, since the probability that the candidate cell is the switching target is small when the L1-RSRP of the candidate cell is low, in order to reduce the measurement frequency, in this embodiment, after receiving the first information, the terminal device divides the priority of all candidate cells that satisfy L1-RSRP≥low reference signal received power threshold, and does not divide the priority and measure the candidate cells that satisfy L1-RSRP<low reference signal received power threshold.

[0118] The candidate cell of the fourth priority is a candidate cell with higher L1-RSRP. The terminal device determines whether the candidate cell is of the fourth priority based on the priority division parameter, the measurement parameter, and the reference signal received power of the candidate cell. For example, the candidate cell of the fourth priority needs to satisfy the following conditions: the reference signal received power is greater than or equal to a low reference signal received power threshold; the signal reference signal received power in a measurement period of m consecutive candidate cells of the fourth priority is greater than a sum of a high reference signal received power threshold and a priority switching hysteresis; and the reference signal received power is greater than or equal to a reference signal received power of an n th cell in a reference signal received power ranking, where the reference signal received power ranking is a ranking of the reference signal received power of the candidate cell from high to low, that is, the candidate cells are arranged in descending order of the corresponding reference signal received power to obtain the reference signal received power ranking, n is the number of candidate cells of the fourth priority allowed to exist simultaneously, and m is an integer greater than or equal to 1, and m is 2 in this embodiment. Since there is a non-instantaneous response characteristic due to changes in input conditions during the switching process, the priority switching hysteresis is introduced in the comparison to avoid frequent switching caused by input signal fluctuations or noise. Moreover, since this embodiment is to avoid fluctuations in the reference signal received power caused by input signal fluctuations, the priority switching hysteresis is a power value.

[0119] The candidate cell of the fifth priority is a candidate cell with lower L1-RSRP but still higher than the low reference signal received power threshold, or a candidate cell with higher L1-RSRP but outside the top n candidate cells in the ranking from high to low. The terminal device determines whether the candidate cell is of the fifth priority based on the priority division parameter, the measurement parameter, and the reference signal received power of the candidate cell. For example, the reference signal received power of the candidate cell of the fifth priority is greater than or equal to the low reference signal received power threshold and less than the difference between the high reference signal received power threshold and the priority switching hysteresis. Alternatively, the reference signal received power of the candidate cell of the fifth priority is greater than or equal to the low reference signal received power threshold, the signal reference signal received power in a measurement period of m consecutive candidate cells of the fourth priority is greater than the sum of the high reference signal received power threshold and the priority switching hysteresis, and the reference signal received power is less than the reference signal received power of the n th cell in the reference signal received power ranking, where the reference signal received power ranking is a ranking of the reference signal received power of the candidate cell from high to low.

[0120] S403: The terminal device generates a measurement report at a measurement occasion corresponding to the priority of the candidate cell, where the priority is used to determine the frequency of generating the measurement report, and the priority of the candidate cell is positively correlated with the frequency of generating the measurement report.

[0121] After the terminal device determines that the candidate cell is of the fourth priority, the terminal device immediately starts measurement on the candidate cell of the fourth priority, and performs the measurement according to a measurement period of the candidate cell of the fourth priority. That is, when the priority of the candidate cell is the fourth priority, the measurement occasion is that the terminal device determines that the candidate cell is of the fourth priority. Since the terminal device divides the priorities in a short time, the measurement occasion can also be that the first information is received. The measurement period of the candidate cell of the fourth priority is high-frequency detection.

[0122] To avoid resource conflicts, after the terminal device determines that the candidate cell is of the fifth priority, the terminal device performs measurement on the candidate cell of the fifth priority in the measurement gap of the fourth cell, and performs the measurement according to a measurement period of the candidate cell of the fifth priority. That is, when the priority of the candidate cell is the fifth priority, the measurement occasion is the measurement gap of the fourth cell. The measurement period of the candidate cell of the fifth priority is low-frequency detection, and the measurement period of the candidate cell of the fourth priority is shorter than the measurement period of the candidate cell of the fifth priority.

[0123] S404: The terminal device sends second information, and the second information is used to indicate a measurement report. Correspondingly, the network device receives the second information.

[0124] The second information is used to carry the measurement report, and the measurement report at least includes a parameter required by the network device to be provided by the terminal device and a priority of a current cell (ue assigned prio).

[0125] For measurement reports of candidate cells of different priorities, different periods are used for reporting in this embodiment, and the higher the priority, the higher the corresponding reporting period. For example, when the priority of the candidate cell is the fourth priority, the reporting period of the candidate cell of the fourth priority is used for reporting. When the priority of the candidate cell is the fifth priority, the reporting period of the candidate cell of the fifth priority is used for reporting. The reporting period of the candidate cell of the fourth priority is shorter than the reporting period of the candidate cell of the fifth priority.
