Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method and device for measuring relaxation. Background Art

[0002] In a serving cell, a terminal device needs to perform radio resource management (RRM) measurements on the serving cell or a neighboring cell to determine whether to continue communicating in the current cell or reselect or switch to another cell with better channel quality for communication.

[0003] Exemplarily, the measurement relaxation criteria include a low-speed movement criterion. For example, if a change in the reference signal receiving power (RSRP) measured by the terminal device is less than a certain threshold over a period of time, the terminal device may perform measurement relaxation.

[0004] However, the above measurement criteria cannot enable the terminal device to effectively perform measurement relaxation. Summary of the Invention

[0005] The present application provides a measurement relaxation method and apparatus to solve the technical problem in the prior art that terminal equipment cannot effectively perform measurement relaxation.

[0006] In a first aspect, an embodiment of the present application provides a measurement relaxation method, which can be applied to a terminal device (also referred to as user equipment (UE), terminal, etc.), or a chip, etc., which can be provided in the terminal device. The method includes:

[0007] Obtain a reference signal received power (RSRP) of a terminal device; when the RSRP value is greater than an RSRP threshold, determine whether to perform measurement relaxation according to a change in the RSRP value and a first RSRP change threshold; when the RSRP value is not greater than the RSRP threshold, determine whether to perform measurement relaxation according to a change in the RSRP value and a second RSRP change threshold, wherein the first RSRP change threshold is greater than the second RSRP change threshold.

[0008] Exemplarily, the above method may be replaced by: when the RSRP value is greater than the RSRP threshold, determining whether to perform measurement relaxation based on the change in the RSRP value and the first RSRP change threshold. Alternatively, when the RSRP value is greater than the RSRP threshold, determining whether to perform measurement relaxation based on whether the change in the RSRP value is less than the first RSRP change threshold. Alternatively, when the RSRP value is not less than the RSRP threshold, determining whether to perform measurement relaxation based on the change in the RSRP value and the first RSRP change threshold, etc.

[0009] The above technical solution provided by this application can effectively improve the problem of setting only one RSRP change threshold (such as S SearchDeltaP The UE at the center of the cell cannot perform measurement relaxation, or the UE at the edge of the cell can perform measurement relaxation even if it is not in a low-speed moving state, which effectively improves the situation where only one S is set. SearchDeltaP This results in the problem that some terminal devices cannot effectively perform measurement relaxation. Therefore, through the method provided by this application, the UE can more reasonably and effectively determine whether to perform measurement relaxation.

[0010] In a possible implementation, a change in the RSRP value with distance within an interval greater than the RSRP threshold is greater than a change in the RSRP value with distance within an interval not greater than the RSRP threshold.

[0011] Optionally, the first change curve is closer to a logarithmic change curve than the second change curve. Optionally, the second change curve is closer to a linear change curve than the first change curve. The first change curve is a curve showing the change of the RSRP value with distance in an interval greater than the RSRP threshold, and the second change curve is a curve showing the change of the RSRP value with distance in an interval not greater than the RSRP threshold. Optionally, the RSRP value changes approximately logarithmically with distance in an interval greater than the RSRP threshold, or the RSRP value changes approximately linearly with distance in an interval not greater than the RSRP threshold. The approximation shown in the embodiments of the present application can be understood as relative similarity, such as the curve showing the change of the RSRP value with distance in an interval greater than the RSRP threshold is approximately logarithmic relative to the interval not greater than the RSRP threshold.

[0012] In one possible implementation, determining whether to perform measurement relaxation based on the change in the RSRP value and a first RSRP change threshold includes: performing measurement relaxation when the change in the RSRP value is less than the first RSRP change threshold within a first duration threshold; or not performing measurement relaxation when the change in the RSRP value is not less than the first RSRP change threshold within the first duration threshold.

[0013] The above method may also be replaced by: if the change in the RSRP value of the UE is less than the first RSRP change threshold within the first duration threshold, the UE is considered to be in a low mobility state and measurement relaxation can be performed. Alternatively, if the change in the RSRP value is less than the first RSRP change threshold within the first duration threshold, the UE may choose to perform measurement relaxation. Otherwise, the UE does not perform measurement relaxation.

[0014] Generally, if only one S is set SearchDeltaP , the S SearchDeltaP When the RSRP change of the UE at the cell center is determined based on the UE at the cell edge, the RSRP change of the UE at the cell center is often greater than S SearchDeltaP , which makes it impossible for the UE to perform measurement relaxation even if it is in a low-speed moving state. However, in the embodiment of the present application, when the RSRP value of the UE is greater than the RSRP threshold, it means that the UE is close to the base station, so the UE can perform measurement relaxation by using the first RSRP change threshold (i.e., the larger RSRP change threshold). In other words, through the embodiment of the present application, UEs that are close to the base station can reasonably and effectively perform measurement relaxation.

[0015] In one possible implementation, determining whether to perform measurement relaxation based on the change in the RSRP value and the second RSRP change threshold includes: performing measurement relaxation when the change in the RSRP value is less than the second RSRP change threshold within the second duration threshold; or not performing measurement relaxation when the change in the RSRP value is not less than the second RSRP change threshold within the second duration threshold.

[0016] It is understandable that the description of the second RSRP change threshold can refer to the first RSRP change threshold, which will not be described in detail here.

[0017] Generally, if only one S is set SearchDeltaP , the S SearchDeltaP When the RSRP change of the UE at the cell center is determined, the RSRP change of the UE at the cell edge is often smaller than that of the S searchDeltaP , which causes the UE to often perform measurement relaxation even if it is not in a low-speed moving state. However, in the embodiment of the present application, when the RSRP value of the UE is not greater than the RSRP threshold, it means that the UE is far away from the base station. Therefore, the UE can perform measurement relaxation by using the second RSRP change threshold (i.e., a smaller RSRP change threshold). In other words, through the embodiment of the present application, UEs that are far away from the base station can reasonably and effectively perform measurement relaxation.

[0018] In a possible implementation, the method further includes: receiving a measurement parameter broadcast by a network device, where the measurement parameter is used to indicate an RSRP threshold, a first RSRP variation threshold, and a second RSRP variation threshold.

[0019] In a possible implementation, the measurement parameter is further used to indicate: a first duration threshold and a second duration threshold.

[0020] It is understandable that when the first duration threshold and the second duration threshold are the same, the network device may only broadcast one duration threshold, such as the first duration threshold or the second duration threshold.

[0021] In a second aspect, an embodiment of the present application provides a measurement relaxation method, which can be applied to a terminal device, a chip, etc., and includes:

[0022] Obtain a reference signal received power RSRP value of the terminal device; when the RSRP value is greater than an RSRP threshold, determine whether to perform measurement relaxation according to a change in the RSRP value within a first duration threshold; when the RSRP value is not greater than the RSRP threshold, determine whether to perform measurement relaxation according to a change in the RSRP value within a second duration threshold, and the first duration threshold is less than the second duration threshold.

[0023] Exemplarily, the above method may be replaced by: when the RSRP value is greater than the RSRP threshold, determining whether to perform measurement relaxation based on the change in the RSRP value within the first duration threshold. Alternatively, when the RSRP value is greater than the RSRP threshold, determining whether to perform measurement relaxation based on whether the change in the RSRP value within the first duration threshold is less than the first RSRP change threshold. Alternatively, when the RSRP value is not less than the RSRP threshold, determining whether to perform measurement relaxation based on the change in the RSRP value within the first duration threshold, etc.

[0024] The above technical solution provided by this application can effectively improve the SearchDeltaP The UE at the center of the cell cannot perform measurement relaxation, or the UE at the edge of the cell can perform measurement relaxation even if it is not in a low-speed moving state, which effectively improves the situation where only one T is set. SearchDeltaP This results in the problem that some terminal devices cannot effectively perform measurement relaxation. Therefore, through the method provided by this application, the UE can more reasonably and effectively determine whether to perform measurement relaxation.

[0025] In a possible implementation, a change in the RSRP value with distance within an interval greater than the RSRP threshold is greater than a change in the RSRP value with distance within an interval not greater than the RSRP threshold.

[0026] For the specific description of the embodiments of the present application, please refer to the first aspect and will not be described in detail here.

[0027] In one possible implementation, determining whether to perform measurement relaxation based on the change in the RSRP value within the first duration threshold includes: performing measurement relaxation when the change in the RSRP value within the first duration threshold is less than the first RSRP change threshold; or not performing measurement relaxation when the change in the RSRP value within the first duration threshold is not less than the first RSRP change threshold.

[0028] The above method can also be replaced by: if the change in the RSRP value within the first duration threshold is less than the first RSRP change threshold, measurement relaxation is performed; otherwise, measurement relaxation is not performed. For detailed description of the embodiments of the present application, please refer to the following, which will not be described in detail here.

[0029] Generally, if only one T is set SearchDeltaP , the T SearchDeltaP When the setting is larger, the T SearchDeltaP The RSRP change of a UE at the center of an inner cell is often greater than the RSRP change threshold, which makes it impossible for the UE to perform measurement relaxation, even if it is in a low-speed moving state. However, in the embodiment of the present application, when the RSRP value of the UE is greater than the RSRP threshold, it means that the UE is close to the base station, so the UE can perform measurement relaxation by using the first duration threshold (i.e., a smaller duration threshold). In other words, through the embodiment of the present application, UEs that are closer to the base station can reasonably and effectively perform measurement relaxation.

[0030] In one possible implementation, determining whether to perform measurement relaxation based on the change in the RSRP value within the second duration threshold includes: when the change in the RSRP value within the second duration threshold is less than the second RSRP change threshold, performing measurement relaxation, and the first RSRP change threshold is greater than the second RSRP change threshold; or, when the change in the RSRP value within the second duration threshold is not less than the second RSRP change threshold, determining not to perform measurement relaxation, and the first RSRP change threshold is greater than the second RSRP change threshold.

[0031] Generally, if only one T is set SearchDeltaP , the T SearchDeltaP When the setting is small, the T SearchDeltaPThe RSRP change of a UE at the edge of an inner cell is often less than the RSRP change threshold, causing the UE to often perform measurement relaxation, even if it is not in a low-speed moving state. However, in the embodiment of the present application, if the RSRP value of the UE is not greater than the RSRP threshold, it means that the UE is far away from the base station, so the UE can perform measurement relaxation by using the second duration threshold (i.e., the larger duration threshold). In other words, through the embodiment of the present application, UEs that are far away from the base station can reasonably and effectively perform measurement relaxation.

[0032] In a possible implementation, the method further includes: receiving a measurement parameter broadcast by a network device, where the measurement parameter is used to indicate an RSRP threshold, a first duration threshold, and a second duration threshold.

[0033] In a possible implementation, the measurement parameter is further used to indicate: a first RSRP change threshold and a second RSRP change threshold.

[0034] It is understandable that when the first RSRP change threshold and the second RSRP change threshold are the same, the network device may broadcast only one RSRP change threshold, such as the first RSRP change threshold or the second RSRP change threshold.

[0035] In a third aspect, an embodiment of the present application provides a measurement relaxation method, which can be applied to a terminal device, a chip, etc., and includes:

[0036] Obtain a change in the beam received by the terminal device and a reference signal received power RSRP value; when the RSRP value is greater than the RSRP threshold, determine whether to perform measurement relaxation according to the change in the beam within a third duration threshold; when the RSRP value is not greater than the RSRP threshold, determine whether to perform measurement relaxation according to the change in the beam within a fourth duration threshold, and the third time threshold is less than the fourth time threshold.

[0037] Exemplarily, the terminal device may first obtain its RSRP value, determine whether to use the third duration threshold or the fourth duration threshold for measurement relaxation, and then obtain the change in the received beam within the third duration threshold or the fourth duration threshold. It will be understood that the embodiment of the present application does not limit the time interval between the terminal device obtaining its RSRP value and obtaining the change in the received beam within the third duration threshold or the fourth duration threshold, such as if the time interval is less than a certain duration threshold.

[0038] The method provided in the embodiment of the present application can determine whether to perform measurement relaxation based on the RSRP value of the UE and the size of the RSRP threshold and the change in the beam received by the UE, so that the UE can more reasonably determine whether to perform measurement relaxation.

[0039] In a possible implementation, the amount of change in the beam with distance in an interval greater than the RSRP threshold is greater than the amount of change in the beam with distance in an interval not greater than the RSRP threshold.

[0040] In a possible implementation, the change includes a change in quantity or a change in quality.

[0041] In one possible implementation, determining whether to perform measurement relaxation based on the amount of change of the beam within the third time length threshold includes: performing measurement relaxation when the amount of change of the beam within the third time length threshold is less than the first beam change amount threshold; or not performing measurement relaxation when the amount of change of the beam within the third time length threshold is not less than the first beam change amount threshold.

[0042] Generally, if only one time threshold is set (e.g., T cross Indicates), the T cross When the setting is larger, the T cross The beam variation of a UE at the center of an inner cell is often greater than the beam variation threshold, which results in the UE being unable to perform measurement relaxation even if it is in a low-speed moving state. However, in the embodiment of the present application, when the RSRP value of the UE is greater than the RSRP threshold, it indicates that the UE is relatively close to the base station, so the UE can perform measurement relaxation by using the third duration threshold (i.e., a smaller duration threshold). In other words, through the embodiment of the present application, UEs that are relatively close to the base station can reasonably and effectively perform measurement relaxation.

[0043] In one possible implementation, determining whether to perform measurement relaxation based on the amount of change of the beam within the fourth time length threshold includes: performing measurement relaxation when the amount of change of the beam within the fourth time length threshold is less than the second beam change amount threshold; or not performing measurement relaxation when the amount of change of the beam within the fourth time length threshold is not less than the second beam change amount threshold.

[0044] Generally, if only one T is set cross , the T cross When the setting is small, the T cross The beam variation of a UE at the edge of an inner cell is often less than the beam variation threshold, causing the UE to frequently perform measurement relaxation, even if it is not in a low-speed moving state. However, in the embodiment of the present application, if the RSRP value of the UE is not greater than the RSRP threshold, it indicates that the UE is far away from the base station. Therefore, the UE can perform measurement relaxation by using the fourth duration threshold (i.e., the larger duration threshold). In other words, through the embodiment of the present application, UEs that are far away from the base station can reasonably and effectively perform measurement relaxation.

[0045] In a possible implementation, the method further includes: receiving a measurement parameter broadcast by a network device, where the measurement parameter is used to indicate an RSRP threshold, a third duration threshold, and a fourth duration threshold.

[0046] In a possible implementation, the measurement parameter is further used to indicate: a first beam variation threshold and a second beam variation threshold.

[0047] It can be understood that when the first beam variation threshold and the second beam variation threshold are the same, the network device may only broadcast one beam variation threshold, such as the first beam variation threshold or the second beam variation threshold.

[0048] In a fourth aspect, an embodiment of the present application provides a measurement relaxation method, which can be applied to a terminal device, a chip, etc., and includes:

[0049] Obtain a change in the beam received by the terminal device and a reference signal received power RSRP value; when the RSRP value is greater than an RSRP threshold, determine whether to perform measurement relaxation based on the change in the beam and a first beam change threshold; when the RSRP value is not greater than the RSRP threshold, determine whether to perform measurement relaxation based on the change in the beam and a second beam change threshold, and the first beam change threshold is greater than the second beam change threshold.

[0050] In a possible implementation, the amount of change in the beam with distance in an interval greater than the RSRP threshold is greater than the amount of change in the beam with distance in an interval not greater than the RSRP threshold.

[0051] In a possible implementation, the change includes a change in quantity or a change in quality.

[0052] In one possible implementation, determining whether to perform measurement relaxation based on the change amount of the beam and the first beam change amount threshold includes: performing measurement relaxation when the change amount of the beam within a third time length threshold is less than the first beam change amount threshold; or not performing measurement relaxation when the change amount of the beam within the third time length threshold is not less than the first beam change amount threshold.

[0053] Generally, if only one beam variation is set (such as can be represented by N or Q), when the beam variation is determined based on the UE at the edge of the cell, the beam variation of the UE at the center of the cell is often greater than the beam variation, resulting in the UE being unable to perform measurement relaxation, even if it is in a low-speed moving state. However, in an embodiment of the present application, when the RSRP value of the UE is greater than the RSRP threshold, it means that the UE is closer to the base station, so the UE can perform measurement relaxation through the first beam variation threshold (i.e., a larger beam variation threshold). In other words, through the embodiment of the present application, UEs that are closer to the base station can reasonably and effectively perform measurement relaxation.

[0054] In one possible implementation, determining whether to perform measurement relaxation based on the change amount of the beam and the second beam change amount threshold includes: performing measurement relaxation when the change amount of the beam within a fourth time length threshold is less than the second beam change amount threshold; or not performing measurement relaxation when the change amount of the beam within the fourth time length threshold is not less than the second beam change amount threshold.

[0055] Generally, if only one beam variation is set, and the beam variation is determined based on the UE at the center of the cell, the beam variation of the UE at the edge of the cell will often be smaller than the beam variation, causing the UE to often relax its measurements even if it is not in a low-speed moving state. However, in an embodiment of the present application, when the RSRP value of the UE is not greater than the RSRP threshold, it means that the UE is far away from the base station, so the UE can relax its measurements by using a second beam variation threshold (i.e., a smaller beam variation threshold). In other words, through the embodiment of the present application, UEs that are far away from the base station can reasonably and effectively relax their measurements.

[0056] In a possible implementation, the method further includes: receiving measurement parameters broadcast by a network device, where the measurement parameters are used to indicate an RSRP threshold, a first beam variation threshold, and a second beam variation threshold.

[0057] In a possible implementation, the measurement parameter is further used to indicate: a third duration threshold and a fourth duration threshold.

[0058] It is understandable that the description of the measurement parameters can refer to the first aspect, the second aspect, or the third aspect, and will not be described in detail here.

[0059] In a fifth aspect, an embodiment of the present application provides a measurement relaxation method, which is applied to a terminal device or a chip, etc., and includes:

[0060] A measurement parameter is received, where the measurement parameter is used to indicate a first RSRP threshold and a second RSRP threshold; and measurement relaxation is performed according to the first RSRP threshold or the second RSRP threshold, where the second RSRP threshold is greater than the first RSRP threshold.

[0061] In the embodiment of the present application, the first RSRP threshold and the second RSRP threshold can be applied to the not at cell edge criterion. The not at cell edge criterion does not take into account the situation where the reduced capability (Redcap) UE has poor coverage. If the Redcap UE and the legacy UE share an S SearchThresholdP , a Redcap UE may receive a very poor RSRP and be unable to receive data normally, let alone use this threshold to determine RRM measurement relaxation. Therefore, the method provided by the embodiment of the present application can effectively improve the situation where a reduced-capability UE cannot perform measurement relaxation due to poor coverage, so that both reduced-capability UEs and traditional UEs can effectively perform measurement relaxation.

[0062] In one possible implementation, when the number of receiving antennas is greater than a preset number, measurement relaxation is performed according to a first RSRP threshold; or, when the number of receiving antennas is less than or equal to a preset number, measurement relaxation is performed according to a second RSRP threshold.

[0063] Exemplarily, the above-mentioned preset number can be 1 or 2, etc., which is not limited in the embodiment of the present application.

[0064] Alternatively, the above implementation may be replaced by: when the number of receiving antennas is not less than a preset number, performing measurement relaxation based on a first RSRP threshold; or, when the number of receiving antennas is less than a preset number, performing measurement relaxation based on a second RSRP threshold. For example, the above preset number may be 2 or 3, etc., and this embodiment of the present application is not limited thereto.

[0065] In one possible implementation, when the transceiver capability is a first transceiver capability, measurement relaxation is performed according to a first RSRP threshold; or, when the transceiver capability is a second transceiver capability, measurement relaxation is performed according to a second RSRP threshold, and the first transceiver capability is greater than the second transceiver capability.

[0066] In one possible implementation, when the terminal device is a traditional terminal device, measurement relaxation is performed according to a first RSRP threshold; or, when the terminal device is a terminal device with reduced capability, measurement relaxation is performed according to a second RSRP threshold.

[0067] It is understood that the first RSRP threshold shown in the embodiment of the present application can also be replaced by a first RSRQ threshold, and the second RSRP threshold can also be replaced by a second RSRQ threshold. For example, a measurement parameter is received, the measurement parameter is used to indicate a first RSRQ threshold and a second RSRQ threshold; measurement relaxation is performed based on the first RSRQ threshold or the second RSRQ threshold, and the second RSRQ threshold is greater than the first RSRQ threshold.

[0068] Optionally, the terminal device may also perform measurement relaxation based on a first RSRP threshold and a first RSRQ threshold; or, perform measurement relaxation based on a second RSRP threshold and a second RSRQ threshold, etc.

[0069] It is understandable that the specific description of the fifth aspect can be found below and will not be elaborated here.

[0070] In a sixth aspect, an embodiment of the present application provides a measurement relaxation method, which is applied to a network device or a chip in a network device, and includes:

[0071] The network device determines measurement parameters and broadcasts the measurement parameters, where the measurement parameters are used to indicate the RSRP threshold, and the measurement parameters also include two or more of the following parameters: a first RSRP change threshold and a second RSRP change threshold; a first duration threshold and a second duration threshold; a first beam change threshold and a second beam change threshold; a third duration threshold and a fourth duration threshold; a first RSRP threshold and a second RSRP threshold.

[0072] It can be understood that the specific description of the above parameters can be referred to the above first to fifth aspects, which will not be described in detail here.

[0073] It is understandable that in the above different embodiments, the values ​​of the same parameters may be the same or different, and the embodiments of the present application do not limit this.

[0074] It can be understood that in the methods shown in the first to sixth aspects above, optionally, the RSRP threshold can be replaced by a reference signal receiving quality (RSRQ) threshold, and the RSRP value can be replaced by an RSRQ value. For example, the first RSRP variation threshold can be replaced by a first RSRQ variation threshold, and the second RSRP variation threshold can be replaced by a second RSRQ variation threshold. Optionally, the RSRP threshold can be replaced by a distance threshold. For example, the above-mentioned RSRP value being greater than the RSRP threshold can be replaced by the distance between the terminal device and the serving base station being less than the distance threshold. For example, the RSRP value not being greater than the RSRP threshold can be replaced by the distance between the terminal device and the serving base station being not less than the distance threshold.

[0075] It can be understood that the method of using RSRP to perform measurement relaxation shown in this application can also be combined with the method of using RSRQ to perform measurement relaxation.

[0076] In a seventh aspect, an embodiment of the present application provides a communication device for executing the method in any aspect or any possible implementation of the first to fifth aspects. The communication device includes a corresponding unit having the function of executing the method in the first to fifth aspects or any possible implementation.

[0079] Exemplarily, the communication device may be a network device or a chip, etc.

[0080] In the seventh aspect or the eighth aspect, the communication device may include a transceiver unit and a processing unit. For a detailed description of the transceiver unit and the processing unit, reference may also be made to the device embodiments shown below.

[0081] In a ninth aspect, an embodiment of the present application provides a communication device, comprising a processor configured to execute the method described in any of the first to fifth aspects or any possible implementation thereof. Alternatively, the processor is configured to execute a program stored in a memory, and when the program is executed, the method described in any of the first to fifth aspects or any possible implementation thereof is executed.

[0082] In a possible implementation, the memory is located outside the communication device.

[0083] In a possible implementation, the memory is located within the above-mentioned communication device.

[0084] In the embodiment of the present application, the processor and the memory may also be integrated into one device, that is, the processor and the memory may also be integrated together. For example, the memory may be used to store measurement parameters, such as the RSRP threshold, the first RSRP change threshold, and the second RSRP change threshold.

This application does not limit the specific form of the terminal device when applied to the Internet of Vehicles. For ease of description, the following will take the terminal device as an example to introduce the method involved in this application.

[0120] Figure 1 The communication system shown in FIG. 1 includes a base station and six UEs. Figure 1 UE1 to UE4 in the figure. It is understood that the specific description of UE and base station can be referred to above and will not be repeated here. Figure 1 The figure shows an example of a base station and four UEs (e.g., UE1, UE3, and UE4 can be mobile phones, and UE2 can be a car), as well as the communication links between the communication devices (e.g., Figure 1 Optionally, the communication system may include multiple base stations, and each base station may include other numbers of UEs within its coverage area, such as more or fewer UEs, etc., which is not limited in this application. Figure 1 The communication system shown may also include core network equipment, such as access and mobility management function (AMF), etc., which is not limited in this application.

[0121] Generally, the UE needs to report the RSRP of the serving cell or neighboring cell, and then determine whether to perform cell handover or cell reselection based on the RSRP. However, in order to save power, the UE can perform radio resource management (RRM) measurements on the serving cell or neighboring cell.

[0122] For example, the RRM criteria may include a low mobility criterion and a not at cell edge criterion, as shown below:

[0123] Slow-speed movement rule: At time T SearchDeltaP If the RSRP change is less than S SearchDeltaP , then the UE is considered to be in a low-speed moving state and measurement relaxation can be performed.

[0124] Not at the cell edge criterion: If the UE’s RSRP is greater than the threshold S SearchThresholdP , it is considered that the UE is not at the cell edge and measurement relaxation can be performed.

[0125] For example, if the network device is configured with only the low-speed mobility criterion but not the non-cell edge criterion (e.g., the network device broadcasts T SearchDeltaP and S SearchDeltaP ), the UE can determine whether the low-speed mobility criterion is met, and if so, the measurement can be relaxed. For another example, if the network device is only configured with the non-cell edge criterion but not the low-speed mobility criterion (such as the network device broadcasts S SearchThresholdP ), the UE can determine whether the non-cell-edge criterion is met, and if so, can perform measurement relaxation. For another example, if the network device is configured with both a low-speed mobility criterion and a cell-edge criterion, the UE can perform measurement relaxation as long as either the low-speed mobility criterion or the cell-edge criterion is met. Alternatively, the UE can perform measurement relaxation only when both the low-speed mobility criterion and the cell-edge criterion are met.

[0126] Optionally, the network device can also configure whether to allow measurement relaxation for high-priority frequencies. Neighbor cell measurements include one or more of the following: same-frequency neighbor cell measurements, different-frequency neighbor cell measurements, and different-system neighbor cell measurements. Optionally, the methods for relaxing measurements may include, but are not limited to, one or more of the following: extending the measurement period, reducing the number of measurement frequencies or cells, reducing the reference signals for measurement, etc. For example, extending the measurement period may include one or more of the following: extending the measurement period to three times the original measurement period, extending the measurement period to one hour, not measuring neighbor cells, etc.

[0127] However, the above-mentioned measurement criteria for low-speed movement have the following problems:

[0128] Question 1:

[0129] For example, in the line of sight (LOS) scenario, if PL = 32.4 + 20*lg(d) + 20*lg(f), when the frequency f = 4 GHz and the base station transmit power is 20 dB, the path loss PL (i.e. Figure 2a The curve of y) changing with distance d (i.e. the distance between UE and base station) is as shown in Figure 2a As shown. Figure 2a It can be seen that when the UE is close to the base station, the path loss increases with the distance in an approximately logarithmic function rather than a linear function; when the UE is far away from the base station, the path loss increases with the distance in an approximately linear function. It is understandable that Figure 2a In the graph shown, the horizontal axis represents the distance between the UE and the base station (in meters), and the vertical axis represents the path loss (in dB).

[0130] The curve of RSRP received by UE changing with distance is as follows: Figure 2b As shown. Figure 2bIt can be seen that when the UE is closer to the base station, the RSRP decreases with the increase of distance in an approximately logarithmic function, rather than a linear function; when the UE is farther away from the base station, the RSRP decreases with the increase of distance in an approximately linear function. For example, when the UE moves away from the base station at 3km / h, it takes 6 seconds to move from 20m away from the base station to 25m away from the base station, and the RSRP changes by about 2dB; when it moves from 160m away from the base station to 200m away from the base station, it takes 48 seconds, and the RSRP change value is also 2dB. If the movement time is the same (such as 6s), the RSRP change is only 0.3dB. It can be understood that Figure 2b The horizontal axis in the graph shows the distance between the UE and the base station (i.e. Figure 2b The x shown is in meters), and the vertical axis represents the RSRP obtained by the UE (i.e. Figure 2b z is shown in dB).

[0131] At the same time, the above S SearchDxltaP and T SearchDeltaP The base station broadcasts the RSRP value to all UEs through a broadcast message (such as SIB2). In other words, for UEs with the same moving speed, the closer they are to the base station, the greater the change in RSRP value within the same time (or the shorter the time required for the same RSRP change). If the UE's location is not taken into account, and the RSRP value is only transmitted through the same S SearchDeltaP and T SearchDeltaP The value of S is used to determine whether low mobility is satisfied and the terminal device cannot effectively perform measurement relaxation. SearchDeltaP and T SearchDeltaP The value is determined based on the UE at the edge of the cell, so the UE at the center of the cell may be affected by the RSRP change being greater than the preset threshold (i.e., S SearchDeltaP ) and measurement relaxation cannot be performed even if the UE is in a low mobility state. For example, if S SearchDeltaP and T SearchDeltaP The value is determined based on the UE at the center of the cell. Then, the UE at the edge of the cell may relax the measurement because the RSRP change is less than the preset threshold, even if the UE is not in the low mobility state.

[0132] Exemplarily, when the UE meets the low mobility criterion, the UE may perform measurement relaxation in the manner shown in Table 1.

[0133] Table 1

[0134]

[0135] Table 1 can be implemented in the following ways:

[0136] For example, when the UE's RSRP value (expressed as Srxlev) > S IntraSearchP When (if RSRP value is Figure 2c If the RRM measurement is within the smallest circle, no intra-frequency (intra-freq) RRM measurement is performed, and the inter-freq measurement of the high-priority frequency is relaxed.

[0137] For example, Srxlev>S nonIntraSearchP When (if RSRP value is Figure 2c Outside the smallest circle and inside the middle circle), RRM measurements of the same priority and lower priority inter-freq are not performed, and measurements of intra-freq and inter-freq of high-priority frequency points are relaxed.

[0138] For example, Srxlev nonIntraSearchP When (if RSRP value is Figure 2c Outside the middle circle, and inside the largest circle), the inter-freq and intra-freq are measured and relaxed.

[0139] It is understandable that the S shown above IntraSearchP Can also be replaced by S IntraSearchQ , that is, the size of the UE's RSRQ value. nonIntraSearchP Can also be replaced by S nonIntraSearchQ .

[0140] For example, the UE meets the low mobility criteria and RSRP nonIntraSearchP or RSRQ nonIntraSearchQ When the UE is using inter-frequency and inter-RAT frequency points, the UE's RRM measurement interval can be extended to three times the original one; for intra-frequency points, the UE's RRM measurement interval can be extended to three times the original one.

[0141] For example, when the UE meets the low mobility criterion and RSRP>S nonIntraSearchP and RSRQ>S nonIntraSearchQ When high priority frequencies of inter frequency and inter radio access technology (inter RAT), if the network is configured with highPriorityMeasRelax, the UE's RRM measurement interval is K2*T higher_priority_search ; If the network does not configure highPriorityMeasRelax, the UE's RRM measurement interval is T​​​higher_priority_search Alternatively, for inter-frequency and inter-RAT frequencies of equal or lower priority, the UE may not perform measurements (e.g., within one hour). Alternatively, for intra-frequency frequencies, the UE's RRM measurement interval may be extended to three times the original one. higher_priority_search This can be understood as the duration configured by the network device and used to measure the high-priority frequency. K2 can be a fixed coefficient (such as 60). highPriorityMeasRelax can be understood as a parameter configured by the network device to indicate whether the high-priority frequency can be relaxed.

[0142] That is, if S SearchDeltaP and T SearchDeltaP It is configured according to the UE at the cell edge, so S IntraSearchP The configuration will affect the measurement relaxation of intra-frequency and high priority inter-frequency. Figure 2d As shown, when S IntraSearchP When in position 1, it affects the measurement relaxation of intra-freq and high-priority inter-freq, S IntraSearchP In position 2, it will affect the measurement relaxation of high priority inter-freq. Figure 2d For instructions, please refer to Figure 2a , I will not go into details here.

[0143] In view of this, the present application provides a measurement relaxation method and apparatus, which enables the UE to more reasonably judge whether to perform measurement relaxation. Optionally, the measurement relaxation of intra-freq and high-priority inter-freq is made more effective. The measurement relaxation method provided by the present application can be as follows: Figure 3 and Figure 4 The method shown.

[0144] Question 2:

[0145] like Figure 2eAs shown, if the UE moves in a circle with the base station as the center, the RSRP of the UE remains unchanged, but the UE is actually moving. Therefore, whether to perform measurement relaxation can be determined by whether the number of beams or the quality of the beams has changed. That is, measurement relaxation is performed through beam-based measurement criteria. For example, the change in the number of beams refers to the change in the beam identifier received by the UE, or the change in the number of beams refers to the number of beams passed by the UE when it moves from one position to another. The change in beam quality refers to the change in the signal strength of the beam received by the UE. For relevant descriptions of the changes in the number of beams and beam quality, please refer to the following text, which will not be described in detail here.

[0146] However, the time it takes for a UE to traverse a beam depends on the distance between the UE and the base station. For example, when a UE is moving at 3 km / h and 10 meters from the base station, it takes approximately 7 seconds to traverse a beam. When the UE is 100 meters from the base station, it takes approximately 70 seconds to traverse a beam. Therefore, it is unreasonable to determine whether to relax measurements based solely on changes in beam quantity or beam quality within a duration threshold (also known as a time threshold).

[0147] In view of this, the present application provides a measurement relaxation method and apparatus, which can determine whether to perform measurement relaxation in combination with the distance between the UE and the base station and the change in the number or quality of beams received by the UE, so that the UE can more reasonably determine whether to perform measurement relaxation. The measurement relaxation method provided by the present application can be used as follows: Figure 5a and Figure 6 The method shown.

[0148] The above measurement criteria for non-cell edge locations have the following problems:

[0149] The not at cell edge criterion does not take into account the poor coverage of reduced capability (Redcap) UEs. If Redcap UEs share an S SearchThresholdP, the Redcap UE may receive a very poor RSRP and be unable to receive data normally, let alone use this threshold to determine RRM measurement relaxation. The Redcap UE is, for example, a UE with fewer than a preset number of receiving antennas, such as a 1R UE, and the traditional UE is, for example, a UE with no fewer than a preset number of receiving antennas, such as a 4R UE, etc. The preset number is, for example, 2, 3, etc., which is not limited in the embodiments of the present application. Alternatively, the Redcap UE is a UE with fewer than or equal to a preset number of receiving antennas, and the traditional UE is a UE with more than a preset number of receiving antennas, such as a preset number of 1, 2, etc., which is not limited in the embodiments of the present application.

[0150] In view of this, the present application provides a measurement relaxation method and device, which can effectively improve the problem that the not at cell edge criterion does not take into account the poor coverage of Redcap UE. The measurement relaxation method provided by the present application can be as follows Figure 7 The method shown.

[0151] Figure 3 This is a flow chart of a relaxation measurement method provided in an embodiment of the present application. Figure 3 As shown, the method includes:

[0152] In one possible implementation, Figure 3 The method shown includes step 301 .

[0153] 301. A base station broadcasts a measurement parameter, where the measurement parameter is used to indicate an RSRP threshold, a first RSRP change threshold, and a second RSRP change threshold, where the first RSRP change threshold is greater than the second RSRP change threshold.

[0154] It is understandable that the above measurement parameters can also be configured to the UE through other methods besides broadcasting. When configuring these three parameters to the UE, they can be configured simultaneously or separately, and the embodiments of the present application do not limit this.

[0155] In addition, during the specific implementation process, the RSRP threshold, the first RSRP change threshold, and the second RSRP change threshold can also be obtained by other methods, which are not limited in the embodiment of the present application.

[0156] For example, the first RSRP change threshold can be expressed as S SearchDeltaP1 The second RSRP change threshold can be represented by S SearchDeltaP2Indicates. The first RSRP change threshold and the second RSRP change threshold are used to measure the size of the RSRP change obtained by the UE within a period of time. The embodiment of the present application does not limit the specific values ​​of the first RSRP change threshold and the second RSRP change threshold. Optionally, the RSRP threshold, the first RSRP change threshold and the second RSRP change threshold may be included in the same broadcast message, such as in the system information block (SIB) 2 or other designated SIBs. Optionally, the RSRP threshold may be included in one broadcast message, and the first RSRP change threshold and the second RSRP change threshold may be included in another broadcast message.

[0157] Exemplarily, the base station may broadcast the above-mentioned measurement parameters periodically. The values ​​of the corresponding parameters in the above-mentioned measurement parameters broadcast by the base station may be the same, or the values ​​of the corresponding parameters in the above-mentioned measurement parameters broadcast by the base station may also vary. For example, the RSRP threshold broadcast by the base station for the first time and the RSRP threshold broadcast by the base station for the second time may be different. Exemplarily, the above-mentioned measurement parameters broadcast by different base stations may be the same or different, and the embodiments of the present application are not limited to this. For example, the RSRP threshold broadcast by base station 1 and the RSRP threshold broadcast by base station 2 may be the same or different.

[0158] Correspondingly, the UE receives the measurement parameters broadcast by the base station. And the UE can also determine whether to relax the measurement based on the RSRP threshold and the first RSRP variation threshold or the second RSRP variation threshold. Optionally, the UE can determine whether to relax the measurement based on whether its RSRP value is greater than the RSRP threshold. Optionally, the UE can determine whether to relax the measurement based on whether its RSRP value is less than the RSRP threshold. For example, the UE can relax the measurement based on the RSRP threshold and the first RSRP variation threshold. For another example, the UE can relax the measurement based on the RSRP threshold and the second RSRP variation threshold. Regarding the method for the UE to relax the measurement, reference can also be made to steps 302 and 303, or steps 302 and 304, etc. (including the interval or RSRQ or distance, etc. shown below).

[0159] Optionally, before the base station broadcasts the measurement parameters, the measurement parameters may be determined first. For example, when determining the measurement parameters, the base station may combine the distance to the base station, or Figure 2b Determine the RSRP threshold, etc. The embodiment of the present application does not limit the specific manner in which the base station determines the measurement parameters.

[0160] 302. The UE obtains an RSRP value.

[0161] 303. When the RSRP value is greater than the RSRP threshold, determine whether to perform measurement relaxation according to a change in the RSRP value and a first RSRP change threshold.

[0162] In an embodiment of the present application, when the RSRP value is greater than the RSRP threshold, the UE may first obtain the change in the RSRP value within the first duration threshold, and then determine whether to perform measurement relaxation based on the change in the RSRP value within the first duration threshold and the first RSRP change threshold. Exemplarily, the above step 303 may also be replaced by: when the RSRP value is greater than the RSRP threshold, determining whether to perform measurement relaxation based on the change in the RSRP value and the first RSRP change threshold. Alternatively, when the RSRP value is greater than the RSRP threshold, determining whether to perform measurement relaxation based on whether the change in the RSRP value is less than the first RSRP change threshold. Alternatively, when the RSRP value is not less than the RSRP threshold, determining whether to perform measurement relaxation based on the change in the RSRP value and the first RSRP change threshold, etc.

[0163] There are several implementations for step 303:

[0164] 1. When the RSRP value is greater than the RSRP threshold, if the change in the RSRP value within the first duration threshold is less than the first RSRP change threshold, it is considered that the UE is in a low mobility state and measurement relaxation can be performed.

[0165] 2. When the RSRP value is greater than the RSRP threshold, if the change in the RSRP value is less than the first RSRP change threshold within the first duration threshold, the UE may choose to relax the measurement.

[0166] 3. When the RSRP value is greater than the RSRP threshold, if the change in the RSRP value within the first duration threshold is not greater than the first RSRP change threshold, the UE may choose to relax the measurement.

[0167] 4. When the RSRP value is not less than the RSRP threshold, if the change in the RSRP value is less than the first RSRP change threshold within the first duration threshold, the UE may choose to relax the measurement.

[0168] 5. When the RSRP value is not less than the RSRP threshold, and within the first duration threshold, if the change in the RSRP value is not greater than the first RSRP change threshold, the UE may choose to relax the measurement.

[0169] It is understandable that the five implementations shown above are only examples, and the description of the variations of each of the above implementations falls within the scope of protection of the embodiments of the present application. For example, when the RSRP value is greater than the RSRP threshold, if the change in the RSRP value within the first duration threshold is not less than the first RSRP change threshold, the UE does not perform measurement relaxation (or is not in a low-speed moving state, or the UE does not choose to perform measurement relaxation, etc.). For another example, when the RSRP value is not less than the RSRP threshold, if the change in the RSRP value within the first duration threshold is greater than the first RSRP change threshold, the UE does not perform measurement relaxation, etc., which will not be described in detail one by one.

[0170] Optionally, the amount of change in the RSRP value with distance within an interval greater than the RSRP threshold is greater than the amount of change in the RSRP value with distance within an interval not greater than the RSRP threshold. Optionally, the first change curve is more similar to a logarithmic change curve than the second change curve. Optionally, the second change curve is more similar to a linear change curve than the first change curve. The first change curve is a curve showing the change in the RSRP value with distance within an interval greater than the RSRP threshold, and the second change curve is a curve showing the change in the RSRP value with distance within an interval not greater than the RSRP threshold. Optionally, the RSRP value changes approximately logarithmically with distance within an interval greater than the RSRP threshold, or the RSRP value changes approximately linearly with distance within an interval not greater than the RSRP threshold. The approximation shown in the embodiments of the present application can be understood as relative similarity, such as the curve showing the change in the RSRP value with distance within an interval greater than the RSRP threshold is approximately logarithmic relative to the interval not greater than the RSRP threshold.

[0171] Combine Figure 2b It can be seen that the closer the UE is to the base station, the larger its RSRP value. Therefore, when the UE's RSRP value is greater than the RSRP threshold, the UE can use a larger RSRP variation threshold (i.e., the first RSRP variation threshold). That is, since the variation of the RSRP value of a UE close to the base station is larger, setting a larger RSRP variation threshold improves the problem that even when the UE is moving at a low speed, the UE cannot perform measurement relaxation due to the RSRP variation threshold being set too small. This allows the UE to effectively and reasonably perform measurement relaxation based on its RSRP value and the first RSRP variation threshold, thereby achieving the purpose of saving power consumption.

[0172] It is understood that the description of the RSRP threshold value also applies to the following. Figures 4 to 7 The methods shown in the figure will not be described in detail below.

[0173] 304. When the RSRP value is not greater than the RSRP threshold, determine whether to perform measurement relaxation according to the change in the RSRP value and a second RSRP change threshold.

[0174] Exemplarily, step 304 may be replaced by: if the RSRP value is not greater than the RSRP threshold, determining whether to perform measurement relaxation based on the RSRP value change and a second RSRP change threshold. Alternatively, if the RSRP value is not greater than the RSRP threshold, determining whether to perform measurement relaxation based on whether the RSRP value change is less than the second RSRP change threshold. Alternatively, if the RSRP value is less than the RSRP threshold, determining whether to perform measurement relaxation based on the RSRP value change and the second RSRP change threshold.

[0175] There are several ways to implement step 304:

[0176] 1. When the RSRP value is not greater than the RSRP threshold, if the change in the RSRP value within the second duration threshold is less than the second RSRP change threshold, it is considered that the UE is in a low mobility state and measurement relaxation can be performed.

[0177] 2. When the RSRP value is not greater than the RSRP threshold, if the change in the RSRP value within the second duration threshold is less than the second RSRP change threshold, the UE may choose to relax the measurement.

[0178] 3. When the RSRP value is not greater than the RSRP threshold, and within the second duration threshold, if the change in the RSRP value is not greater than the second RSRP change threshold, the UE may choose to relax the measurement.

[0179] 4. When the RSRP value is less than the RSRP threshold, if the change in the RSRP value is less than the second RSRP change threshold within the second duration threshold, the UE may choose to relax the measurement.

[0180] 5. When the RSRP value is less than the RSRP threshold, if the change in the RSRP value within the second duration threshold is not greater than the second RSRP change threshold, the UE may choose to relax the measurement.

[0181] It is understood that the five implementations shown above are only examples, and the variations of the above implementations are all within the scope of protection of the embodiments of this application and will not be described in detail here. For the specific description of step 304, please refer to the description of step 303, which will not be described in detail here.

[0182] In one possible implementation, Figure 3The method shown can also introduce an RSRP floating threshold (also called a floating variable) such as Δb to alleviate the impact of RSRP instability. Exemplarily, if the RSRP value of the UE is greater than (or not less than) the RSRP threshold + floating threshold, the UE can determine whether to perform measurement relaxation based on the first RSRP variation threshold. Exemplarily, if the RSRP value of the UE is not greater than (or less than) the RSRP threshold - floating threshold, the UE can determine whether to perform measurement relaxation based on the second RSRP variation threshold. Exemplarily, when the RSRP value of the UE is greater than (or not less than) the RSRP threshold - floating threshold, and not greater than (or less than) the RSRP threshold + floating threshold, the UE can determine whether to perform measurement relaxation based on the first RSRP variation threshold or the second RSRP variation threshold. It can be understood that for the specific description of the UE performing measurement relaxation, reference can be made to the above embodiments (such as the description of step 303 or step 304, etc.), which will not be repeated here. For the description of the floating threshold, reference can also be made to the following.

[0183] It is understood that when a floating threshold is used, the floating threshold may also be indicated in the measurement parameters broadcast by the base station. The UE may obtain the floating threshold in other ways, which are not limited in the embodiments of the present application.

[0184] The above is an example of whether the RSRP value of the UE is greater than the RSRP threshold to illustrate the method provided in the embodiment of the present application. However, in some embodiments of the present application, it can also be determined whether to relax the measurement based on the interval in which the RSRP value of the UE is located. That is: the UE can first determine at least two intervals. For example, the base station can broadcast at least two intervals, such as the first interval and the second interval. When the base station broadcasts the first interval and the second interval, whether the first RSRP change threshold and the second RSRP change threshold are included in the same message is not limited in the embodiment of the present application. Alternatively, the base station broadcasts the RSRP threshold, and the UE autonomously divides the first interval and the second interval according to the RSRP threshold. The embodiment of the present application does not limit the maximum value of the first interval and the minimum value of the second interval.

[0185] Optionally, the amount of change in RSRP value with distance in the first interval is greater than the amount of change in RSRP value with distance in the second interval. Optionally, the curve of change in RSRP value with distance in the first interval is more similar to a logarithmic curve than that in the second interval. Optionally, the curve of change in RSRP value with distance in the second interval is more similar to a linear curve than that in the first interval. Optionally, the change in RSRP value with distance in the first interval is approximately logarithmic, and the change in RSRP value with distance in the second interval is approximately linear. Exemplarily, the first interval is [b, a] and the second interval is [c, b]. Alternatively, the first interval is [b, a] and the second interval is [c, b). Alternatively, the first interval is (b, a], and the second interval is [c, b]. For example, the first interval is [-50, -20], and the second interval is [-100, -50]. It can be understood that when the first interval includes -50 and the second interval also includes -50, it means that when the RSRP value of the UE is -50, measurement relaxation can be performed according to the first RSRP change threshold or the second RSRP change threshold.

[0186] For example, if the RSRP value of the UE is within the first interval, the UE can determine whether to perform measurement relaxation based on the first RSRP change threshold. For another example, if the RSRP value of the UE is within the second interval, the UE can determine whether to perform measurement relaxation based on the second RSRP change threshold. It can be understood that for embodiments related to the first interval and the second interval, reference can be made to the above description of the RSRP threshold, which will not be repeated here. For specific instructions on how the UE performs measurement relaxation, reference can be made to the above embodiments (such as the description of step 303 or step 304, etc.), which will not be repeated here.

[0187] Optionally, the method shown in the embodiment of the present application may also introduce an RSRP floating threshold (also referred to as a floating variable) such as Δb to alleviate the impact of RSRP instability. For example, if the RSRP value of the UE is in the interval [b+Δb, a], the UE may determine whether to perform measurement relaxation based on the first RSRP variation threshold. For another example, if the RSRP value of the UE is in the interval [c, b-Δb], the UE may determine whether to perform measurement relaxation based on the second RSRP variation threshold. For another example, if the RSRP value of the UE is in the interval [b-Δb, b+Δb], the UE may determine whether to perform measurement relaxation based on the first RSRP variation threshold or the second RSRP variation threshold. That is, the UE may use the first RSRP variation threshold to determine whether to perform measurement relaxation, or may use the second RSRP variation threshold to determine whether to perform measurement relaxation. It is understandable that for the specific description of the UE performing measurement relaxation, reference may be made to the above embodiments (such as the description of step 303 or step 304, etc.), which will not be repeated here.

[0188] The above is an example of dividing the RSRP value into two intervals, or two intervals and a floating interval. However, in other embodiments of the present application, the RSRP value can also be divided into three intervals or four intervals. For example, the RSRP value is divided into a first interval, a second interval, and a third interval. The change in the RSRP value with distance in the first interval is greater than the change in the RSRP value with distance in the second interval, and the change in the RSRP value with distance in the second interval is greater than the change in the RSRP value with distance in the third interval. Accordingly, the RSRP change threshold may also include a first RSRP change threshold, a second RSRP change threshold, and a third change threshold. If the first RSRP change threshold is greater than the second RSRP change threshold, the second RSRP change threshold is greater than the third change threshold. For example, if the RSRP value of the UE is within the first interval, the UE can determine whether to perform measurement relaxation based on the first RSRP change threshold (or based on the first RSRP change threshold and the first duration threshold). For another example, if the RSRP value of the UE is within the second interval, the UE can determine whether to perform measurement relaxation based on the second RSRP change threshold (or based on the second RSRP change threshold and the second duration threshold). For example, if the RSRP value of the UE is within the third interval, the UE can determine whether to perform measurement relaxation based on the third change threshold (or based on the third change threshold and the third duration threshold). It is understandable that for the specific description of the UE performing measurement relaxation, reference can be made to the above embodiments, which will not be repeated here. It is understandable that for the description of the four intervals, reference can be made to the description of the three intervals, which will not be repeated here. Optionally, a floating threshold can also be introduced to alleviate the impact of RSRP instability. For the specific description of the floating threshold, reference can be made to the above description, which will not be repeated here.

[0189] It is understood that the descriptions of the RSRP threshold, floating threshold, two intervals, three intervals, or four intervals are also applicable to the following text. Figures 4 to 9 The methods shown in the figure will not be described in detail below.

[0190] For each of the above embodiments, in a possible implementation, the first duration threshold and the second duration threshold are the same. SearchDeltaP , such as a larger S SearchDeltaP1 and a smaller S SearchDeltaP2 , and 1 T SearchDeltaP According to the comparison result between the RSRP value of UE and the RSRP threshold, UE can select the larger S SearchDeltaP1 or a smaller S SearchDeltaP2 Determine whether to perform measurement relaxation. For example, if the RSRP value of the UE is greater than the RSRP threshold, SearchDeltaPIf the change in RSRP value (also called RSRP change, etc.) is less than S SearchDeltaP1 , then the UE can relax the measurement. For another example, if the RSRP value of the UE is not greater than the RSRP threshold, SearchDeltaP If the change in RSRP value (also called RSRP change, etc.) is less than S SearchDeltaP2 , then the UE can relax the measurement. For another example, if the RSRP value of the UE is in the interval [b, a], SearchDeltaP If the change in RSRP value (also called RSRP change, etc.) is less than S SearchDeltaP1 , then the UE can relax the measurement. For another example, if the RSRP value of the UE is in the interval [c, b], SearchDeltaP If the change in RSRP value (also called RSRP change, etc.) is less than S SearchDeltaP2 , then the UE can perform measurement relaxation.

[0191] In another possible implementation, the first duration threshold and the second duration threshold are different, for example, the first duration threshold may be smaller than the second duration threshold. SearchDeltaP , such as a larger S SearchDeltaP1 and a smaller S SearchDeltaP2 , and 2 T SearchDeltaP , such as a smaller T SearchDeltaP1 and a larger T SearchDeltaP2 For example, if the RSRP value of the UE is greater than the RSRP threshold, SearchDeltaP1 If the change in RSRP value (also called RSRP change, etc.) is less than S SearchDeltaP1 , then the UE can relax the measurement. For another example, if the RSRP value of the UE is not greater than the RSRP threshold, SearchDeltaP2 If the change in RSRP value (also called RSRP change, etc.) is less than S SearchDeltaP2 , then the UE can relax the measurement. For another example, if the RSRP value of the UE is in the interval [b, a], SearchDeltaP1 If the change in RSRP value (also called RSRP change, etc.) is less than S SearchDeltaP1 , then the UE can relax the measurement. For another example, if the RSRP value of the UE is in the interval [c, b], SearchDeltaP2 If the change in RSRP value (also called RSRP change, etc.) is less than S SearchDeltaP2 , the UE can perform measurement relaxation.

[0192] The above is based on the change in the RSRP value of the UE to determine whether to perform measurement relaxation. However, in some embodiments of the present application, the above RSRP value can also be replaced by the reference signal receiving quality (RSRQ). That is, whether to perform measurement relaxation is determined based on the size of the UE's RSRQ and the RSRQ threshold, as well as the change in the RSRQ value and the RSRQ change threshold. Of course, the UE can determine whether to perform measurement relaxation by other reference signal measurement parameters, and the embodiments of the present application are not limited thereto.

[0193] Exemplarily, the base station broadcasts a measurement parameter, which is used to indicate an RSRQ threshold, a first RSRQ change threshold, and a second RSRQ change threshold. The first RSRQ change threshold is greater than the second RSRQ change threshold. Correspondingly, the UE receives the measurement parameter. The UE obtains an RSRQ value, and when the RSRQ value is greater than the RSRQ threshold, determines whether to perform measurement relaxation based on the change in the RSRQ value and the first RSRQ change threshold. When the RSRQ value is not greater than the RSRQ threshold, determines whether to perform measurement relaxation based on the change in the RSRQ value and the second RSRQ change threshold.

[0194] Exemplarily, the base station broadcasts measurement parameters that indicate an RSRP threshold, an RSRQ threshold, a first RSRP change threshold, a second RSRP change threshold, a first RSRQ change threshold, and a second RSRQ change threshold. In this case, the UE can perform measurement relaxation when both the RSRP and RSRQ criteria are met. Alternatively, the UE can perform measurement relaxation when any one of the criteria is met, etc., which will not be described in detail here.

[0195] It is understood that for the specific description of RSRQ, reference can be made to the description of RSRP in the above embodiment, and no further details will be given here. For example, reference can be made to the above description of steps 303 and 304, or to the above description of the interval, or to the above description of the floating threshold, or to the above description of the first duration threshold or the second duration threshold, etc.

[0196] In other embodiments of the present application, the RSRP threshold may be replaced by a distance threshold, or other parameters that can be used to measure or characterize distance. For example, whether to perform measurement relaxation is determined based on the distance between the UE and the base station and the distance threshold, as well as the RSRP change and the RSRP change threshold. For another example, whether to perform measurement relaxation is determined based on the distance between the UE and the base station and the distance threshold, as well as the RSRQ change and the RSRQ change threshold.

[0197] Exemplarily, the base station broadcasts a measurement parameter that indicates a distance threshold, a first RSRP change threshold, and a second RSRP change threshold. The first RSRP change threshold is greater than the second RSRP change threshold. Correspondingly, the UE receives the measurement parameter. The UE obtains the distance between it and the serving base station. If the distance is less than the distance threshold, the UE determines whether to relax the measurement based on the change in the RSRP value and the first RSRP change threshold. If the distance is not less than the distance threshold, the UE determines whether to relax the measurement based on the change in the RSRP value and the second RSRP change threshold.

[0198] Exemplarily, the base station broadcasts a measurement parameter, which is used to indicate a distance threshold, a first RSRQ change threshold, and a second RSRQ change threshold. The first RSRQ change threshold is greater than the second RSRQ change threshold. Correspondingly, the UE receives the measurement parameter. The UE obtains the distance between it and the serving base station. When the distance is less than the distance threshold, it determines whether to relax the measurement based on the change in the RSRQ value and the first RSRQ change threshold. When the distance is not less than the distance threshold, it determines whether to relax the measurement based on the change in the RSRQ value and the second RSRQ change threshold.

[0199] It is understood that for the specific description of the embodiments of the present application, reference can be made to the description of RSRP or RSRQ in the above embodiments, and no further details will be given here. For example, reference can be made to the above description of steps 303 and 304, or to the above description of the interval, or to the above description of the floating threshold, or to the above description of the first duration threshold or the second duration threshold, or to the above description of RSRQ, etc.

[0200] It is understood that in the various embodiments shown in this application, the values ​​of the same parameters may be the same or different for different embodiments, and the embodiments of this application are not limited to this. For example, the specific values ​​of the first RSRP change threshold (or the second RSRP change threshold, etc.) in the above-mentioned different embodiments may be the same, or the specific values ​​of the first RSRP change threshold (or the second RSRP change threshold, etc.) in the above-mentioned different embodiments may also be different. For this description, the following also applies.

[0201] The methods shown in the above embodiments provided by this application can effectively improve the performance of the system by only setting one S SearchDeltaP , which results in the UE at the center of the cell being unable to perform measurement relaxation, or the UE at the edge of the cell being able to perform measurement relaxation even if it is not in a low-speed moving state, effectively improving the situation where only one S is set SearchDeltaPThis results in some terminal devices being unable to effectively perform measurement relaxation. Therefore, through the method provided by this application, the UE can more reasonably and effectively determine whether to perform measurement relaxation.

[0202] Figure 4 This is a flow chart of a relaxation measurement method provided in an embodiment of the present application. Figure 4 As shown, the method includes:

[0203] In one possible implementation, Figure 4 The method shown includes step 401 .

[0204] 401. A base station broadcasts a measurement parameter, where the measurement parameter is used to indicate an RSRP threshold, a first duration threshold, and a second duration threshold, where the first duration threshold is smaller than the second duration threshold.

[0205] For example, the first duration threshold may also be referred to as the first time threshold or T SearchDeltaP1 The second duration threshold may also be referred to as the second time threshold or T SearchDeltaP2 Etc. The first duration threshold and the second duration threshold are used to measure the duration applied when the UE obtains the RSRP change. The specific values ​​of the first duration threshold and the second duration threshold are not limited in this embodiment of the application. Optionally, the RSRP threshold, the first duration threshold and the second duration threshold can be included in the same broadcast message, such as in SIB2 or other specified SIBs. Optionally, the RSRP threshold can be included in one broadcast message, and the first duration threshold and the second duration threshold can be included in another broadcast message.

[0206] It is understandable that the specific description of step 401 can refer to the above step 301, and will not be described in detail here.

[0207] Correspondingly, the UE receives the measurement parameters broadcast by the base station, and the UE may also determine whether to perform measurement relaxation based on the RSRP threshold and the first duration threshold or the second duration threshold. Regarding the method for the UE to perform measurement relaxation, reference may also be made to steps 402 and 403, or steps 402 and 403, etc. (including the RSRQ or distance, etc. shown below).

[0208] 402. The UE obtains an RSRP value.

[0209] 403. When the RSRP value is greater than the RSRP threshold, determine whether to perform measurement relaxation according to a change in the RSRP value within a first duration threshold.

[0210] Exemplarily, step 403 may be replaced by: if the RSRP value is greater than the RSRP threshold, determining whether to perform measurement relaxation based on the amount of change in the RSRP value within the first duration threshold. Alternatively, if the RSRP value is greater than the RSRP threshold, determining whether to perform measurement relaxation based on whether the amount of change in the RSRP value within the first duration threshold is less than the first RSRP change threshold. Alternatively, if the RSRP value is not less than the RSRP threshold, determining whether to perform measurement relaxation based on the amount of change in the RSRP value within the first duration threshold, etc.

[0211] It is understood that the several implementations of step 403 can refer to the above step 303, and will not be described in detail here. For example, refer to the five implementations of step 303 or the description of the variations.

[0212] It is understandable that the description of RSRP threshold can be referred to Figure 3 Alternatively, you can refer to the method shown in Figure 2b The description of etc. will not be repeated here. For example, the change of the RSRP value with distance in the interval greater than the RSRP threshold is greater than the change of the RSRP value with distance in the interval not greater than the RSRP threshold. For example, when the RSRP change is the same, the duration required by the UE close to the base station is less than that of the UE far from the base station. Therefore, when the RSRP value of the UE is greater than the RSRP threshold, by setting a smaller duration threshold, the problem that the UE cannot perform measurement relaxation even if it is in a low-speed moving state due to the excessively large duration threshold is improved. Thereby, the UE can effectively and reasonably perform measurement relaxation in combination with the change of its RSRP value and the first duration threshold, thereby achieving the purpose of saving power consumption.

[0213] 404. When the RSRP value is not greater than the RSRP threshold, determine whether to perform measurement relaxation according to a change in the RSRP value within a second duration threshold.

[0214] Exemplarily, step 404 may be replaced by: if the RSRP value is not greater than the RSRP threshold, determining whether to perform measurement relaxation based on the change in the RSRP value within the second duration threshold. Alternatively, if the RSRP value is not greater than the RSRP threshold, determining whether to perform measurement relaxation based on whether the change in the RSRP value within the second duration threshold is less than a second RSRP change threshold. Alternatively, if the RSRP value is less than the RSRP threshold, determining whether to perform measurement relaxation based on the change in the RSRP value within the second duration threshold.

[0215] It is understood that the several implementations of step 404 can refer to the above step 304, and will not be described in detail here. For example, refer to the five implementations of step 304 or the description of the variations.

[0216] In one possible implementation, Figure 4 The method shown may also introduce an RSRP floating threshold (also referred to as a floating variable) such as Δb to alleviate the impact of RSRP instability. Exemplarily, if the RSRP value of the UE is greater than the RSRP threshold + floating threshold, the UE may determine whether to perform measurement relaxation based on the first duration threshold. Exemplarily, if the RSRP value of the UE is not greater than the RSRP threshold - floating threshold, the UE may determine whether to perform measurement relaxation based on the second duration threshold. Exemplarily, if the RSRP value of the UE is greater than the RSRP threshold - floating threshold, and less than or equal to the RSRP threshold + floating threshold, the UE may determine whether to perform measurement relaxation based on the first duration threshold or the second duration threshold. It is understood that for the specific description of the UE performing measurement relaxation, reference may be made to the above embodiments (such as Figure 3 The method shown, or the description of step 403 or step 404, etc.) will not be repeated here.

[0217] In some embodiments of the present application, it is also possible to determine whether to perform measurement relaxation based on the interval in which the RSRP value of the UE is located. For example, the base station can broadcast two intervals, such as the first interval and the second interval. When the base station broadcasts the first interval and the second interval, whether they are included in the same message as the first duration threshold and the second duration threshold is not limited in the embodiment of the present application. Alternatively, the base station broadcasts the RSRP threshold, and the UE autonomously divides the first interval and the second interval according to the RSRP threshold. The embodiment of the present application does not limit the maximum value of the first interval and the minimum value of the second interval. For example, if the RSRP value of the UE is within the first interval, the UE can determine whether to perform measurement relaxation based on the change in the RSRP value within the first duration threshold. For another example, if the RSRP value of the UE is within the second interval, the UE can determine whether to perform measurement relaxation based on the change in the RSRP value within the second duration threshold.

[0218] Optionally, the method shown in the embodiment of the present application may also introduce an RSRP floating threshold (also referred to as a floating variable) such as Δb to alleviate the impact of RSRP instability. For example, if the RSRP value of the UE is in the interval [b+Δb, a], the UE may determine whether to perform measurement relaxation based on the amount of change in the RSRP value within the first duration threshold. For another example, if the RSRP value of the UE is in the interval [c, b-Δb], the UE may determine whether to perform measurement relaxation based on the amount of change in the RSRP value within the second duration threshold. For another example, if the RSRP value of the UE is in the interval [b-Δb, b+Δb], the UE may determine whether to perform measurement relaxation based on the amount of change in the RSRP value within the first duration threshold or the amount of change in the RSRP value within the second duration threshold.

[0219] In other embodiments of the present application, the RSRP value may be divided into three intervals or four intervals, etc. For example, the RSRP value is divided into a first interval, a second interval, and a third interval. The change in the RSRP value with distance in the first interval is greater than the change in the RSRP value with distance in the second interval, and the change in the RSRP value with distance in the second interval is greater than the change in the RSRP value with distance in the third interval. Accordingly, the RSRP change threshold may also include a first duration threshold, a second duration threshold, and a third duration threshold. For example, the first duration threshold is less than the second duration threshold, and the second duration threshold is less than the third duration threshold.

[0220] It is understandable that for the description of the first interval, the second interval, the third interval and the floating threshold, reference can be made to the above embodiments, which will not be described in detail here.

[0221] In a possible implementation, the first RSRP change threshold and the second RSRP change threshold are the same. SearchDeltaP , and 2 T SearchDeltaP , such as a smaller T SearchDeltaP1 and a larger T SearchDeltaP2 Based on the comparison between the UE's RSRP value and the RSRP threshold, the UE can select a smaller T SearchDeltaP1 or a larger T SearchDeltaP2 Determine whether to perform measurement relaxation. For example, if the RSRP value of the UE is greater than the RSRP threshold, SearchDeltaP1 If the change in RSRP value (also called RSRP change, etc.) is less than S SearchDeltaP , then the UE can relax the measurement. For another example, if the RSRP value of the UE is not greater than the RSRP threshold, SearchDeltaP2 If the change in RSRP value is less than S SearchDeltaP , then the UE can relax the measurement. For another example, if the RSRP value of the UE is in the interval [b, a], SearchDeltaP1 If the change in RSRP value is less than S SearchDeltaP , then the UE can relax the measurement. For another example, if the RSRP value of the UE is in the interval [c, b], SearchDeltaP2 If the change in RSRP value is less than S SearchDeltaP , the UE can perform measurement relaxation.

[0222] In another possible implementation, the first RSRP change threshold and the second RSRP change threshold are different, such as the first RSRP change threshold is greater than the second RSRP change threshold. SearchDeltaP , such as a larger S SearchDeltaP1 and a smaller S SearchDeltaP2, and 2 T SearchDeltaP , such as a smaller T SearchDeltaP1 and a larger T SearchDeltaP2 It is understood that the specific description of this implementation can be found in Figure 3 The description of the difference between the first duration threshold and the second duration threshold in the illustrated method will not be repeated here in detail.

[0223] In the above, whether to perform measurement relaxation is determined based on the change in the RSRP value of the UE. However, in some embodiments of the present application, the RSRP value can also be replaced by the reference signal receiving quality (RSRQ). In other words, whether to perform measurement relaxation is determined based on the difference between the UE's RSRQ and the RSRQ threshold, as well as the change in the RSRQ value within the first duration threshold (or the second duration threshold).

[0224] Exemplarily, a base station broadcasts a measurement parameter that indicates an RSRQ threshold, a first duration threshold, and a second duration threshold. The first duration threshold is less than the second duration threshold. Correspondingly, the UE receives the measurement parameter. The UE obtains an RSRQ value. If the RSRQ value is greater than the RSRQ threshold, the UE determines whether to perform measurement relaxation based on a change in the RSRQ value within the first duration threshold. If the RSRQ value is not greater than the RSRQ threshold, the UE determines whether to perform measurement relaxation based on a change in the RSRQ value within the second duration threshold.

[0225] Exemplarily, the base station broadcasts measurement parameters that are used to indicate the RSRP threshold, RSRQ threshold, first duration threshold, second duration threshold, fifth duration threshold, and sixth duration threshold. For the description of the fifth duration threshold, reference may be made to the first duration threshold, and for the description of the sixth duration threshold, reference may be made to the second duration threshold, which will not be described in detail here. In this case, the UE may perform measurement relaxation when both the criteria corresponding to RSRP and the criteria corresponding to RSRQ are met. Alternatively, the UE may perform measurement relaxation when any one of the criteria is met, etc., which will not be described in detail here.

[0226] It is understood that the specific description of RSRQ can refer to the above embodiments and will not be described in detail here. For example, reference can be made to the above description of steps 303 and 304 or steps 403 and 404, or to the above description of the interval, or to the above description of the floating threshold, or to the above description of the first RSRP change threshold or the second RSRP change threshold, etc.

[0227] In other embodiments of the present application, the RSRP threshold may be replaced by a distance threshold, or other parameters that can be used to measure or characterize the distance. For example, whether to perform measurement relaxation is determined based on the distance between the UE and the base station and the distance threshold, as well as the change in RSRP within a certain time threshold. For another example, whether to perform measurement relaxation is determined based on the distance between the UE and the base station and the distance threshold, as well as the change in RSRQ within a certain time threshold.

[0228] Exemplarily, the base station broadcasts a measurement parameter indicating a distance threshold, a first duration threshold, and a second duration threshold. The first duration threshold is less than the second duration threshold. Accordingly, the UE receives the measurement parameter. The UE obtains the distance between itself and the serving base station. If the distance is less than the distance threshold, the UE determines whether to perform measurement relaxation based on a change in the RSRP value within the first duration threshold. If the distance is not less than the distance threshold, the UE determines whether to perform measurement relaxation based on a change in the RSRP value within the second duration threshold.

[0229] Exemplarily, the base station broadcasts a measurement parameter that indicates a distance threshold, a first duration threshold, and a second duration threshold. The first duration threshold is less than the second duration threshold. Correspondingly, the UE receives the measurement parameter. The UE obtains the distance between it and the serving base station. If the distance is less than the distance threshold, the UE determines whether to perform measurement relaxation based on the change in the RSRQ value within the first duration threshold. If the distance is not less than the distance threshold, the UE determines whether to perform measurement relaxation based on the change in the RSRQ value within the second duration threshold.

[0230] It is understood that for the specific description of the embodiments of the present application, reference can be made to the description of RSRP or RSRQ in the above embodiments, and no further details will be given here. For example, reference can be made to the above description of steps 403 and 404, or to the above description of the interval, or to the above description of the floating threshold, or to the above description of RSRQ, etc.

[0231] The methods shown in the above embodiments provided by this application can effectively improve the performance of the system by only setting one T SearchDeltaP , which results in the UE at the center of the cell being unable to perform measurement relaxation, or the UE at the edge of the cell being able to perform measurement relaxation even if it is not in a low-speed moving state, effectively improving the situation where only one T is set SearchDeltaP This results in some terminal devices being unable to effectively perform measurement relaxation. Therefore, through the method provided by this application, the UE can more reasonably and effectively determine whether to perform measurement relaxation.

[0232] Figure 5a This is a flow chart of a relaxation measurement method provided in an embodiment of the present application. Figure 5aAs shown, the method includes:

[0233] In one possible implementation, Figure 5a The method shown includes step 501 .

[0234] 501. A base station broadcasts a measurement parameter, where the measurement parameter is used to indicate an RSRP threshold, a third duration threshold, and a fourth duration threshold, where the third duration threshold is smaller than the fourth duration threshold.

[0235] For example, the third duration threshold may also be referred to as a third time threshold or T cross1 The fourth duration threshold may also be referred to as the fourth time threshold or T cross2 Optionally, the RSRP threshold, the third duration threshold, and the fourth duration threshold may be included in the same broadcast message, such as in SIB2 or another designated SIB. Optionally, the RSRP threshold may be included in one broadcast message, and the third duration threshold and the fourth duration threshold may be included in another broadcast message.

[0236] It is understandable that the specific description of step 501 can refer to the above-mentioned step 401 or step 301, etc., and will not be described in detail here.

[0237] Correspondingly, the UE receives the measurement parameters broadcast by the base station, and the UE may also determine whether to perform measurement relaxation based on the RSRP threshold and the third duration threshold or the fourth duration threshold. Regarding the method for the UE to perform measurement relaxation, reference may also be made to steps 502 and 503, or steps 502 and 503, etc.

[0238] 502. The UE obtains an RSRP value.

[0239] 503. When the RSRP value is greater than the RSRP threshold, determine whether to perform measurement relaxation according to a change amount of the beam within a third duration threshold.

[0240] In an embodiment of the present application, when the RSRP value is greater than the RSRP threshold, the UE may also first obtain the amount of change in the beam received within the third duration threshold, and then determine whether to perform measurement relaxation based on the amount of change in the beam within the third duration threshold and the first beam change threshold. Exemplarily, the amount of change in the beam is used to measure whether the beam received by the UE has changed. For example, whether the identifier of the beam received by the UE (such as can be represented by the index of the SSB, etc.) has changed, or whether the signal strength of the beam received by the UE has changed, etc. Any parameter that can measure whether the beam received by the UE has changed falls within the scope of protection of this application.

[0241] Exemplarily, step 503 may be replaced by: if the RSRP value is greater than the RSRP threshold, determining whether to perform measurement relaxation based on the amount of change in the beam within the third duration threshold. Alternatively, if the RSRP value is greater than the RSRP threshold, determining whether to perform measurement relaxation based on whether the amount of change in the beam within the third duration threshold is less than the first beam change threshold. Alternatively, if the RSRP value is not less than the RSRP threshold, determining whether to perform measurement relaxation based on the amount of change in the beam within the third duration threshold, etc.

[0242] There are several implementations for step 503:

[0243] 1. When the RSRP value is greater than the RSRP threshold, if the beam change is less than the first beam change threshold within the third duration threshold, the UE is considered to be in a low mobility state and measurement relaxation can be performed.

[0244] 2. When the RSRP value is greater than the RSRP threshold, if the beam change is less than the first beam change threshold within the third duration threshold, the UE may choose to relax the measurement.

[0245] 3. When the RSRP value is greater than the RSRP threshold, if the beam change amount is not greater than the first beam change amount threshold within the third duration threshold, the UE may choose to relax the measurement.

[0246] 4. When the RSRP value is not less than the RSRP threshold, if the beam change amount is less than the first beam change amount threshold within the third duration threshold, the UE may choose to relax the measurement.

[0247] 5. When the RSRP value is not less than the RSRP threshold, and the beam change amount is not greater than the first beam change amount threshold within the third duration threshold, the UE may choose to relax the measurement.

[0248] It is understandable that the five implementation methods shown above are only examples, and the description of variations of each of the above implementation methods all fall within the protection scope of the embodiments of the present application.

[0249] Generally, each synchronization signal and physical broadcast channel (PBCH) block (SS / PBCH block) (SSB for short) corresponds to a beam. Therefore, the UE can know the beam according to the index of the SSB.

[0250] In the embodiment of the present application, the change amount of the beam may include the change amount of the beam quantity or the change amount of the beam quality. Exemplarily, the change amount of the beam quantity may be implemented as follows:

[0251] For example, when the beam in which the UE is located changes, the UE may learn the number of the changed beams.

[0252] For example, beam indices can be continuous. For example, for beams 1-5, if the UE is currently on beam 3, then beam 3 must have the best quality, beams 2 and 4 are suboptimal, and beams 1 and 5 are the worst. If the UE moves from beam 3 to beam 4, the best beam changes from beam 3 to beam 4, and the UE can thus know that it has passed through one beam. If the UE moves from beam 3 to beam 5 (for example, it can be known from the SSB index that it has moved from beam 3 to beam 5), the best beam becomes beam 5, and the UE can thus know that it has passed through two beams, that is, the change in the number of beams is 2.

[0253] For example, when the signal strength of the beam in which the UE is located is lower than a certain threshold, the UE may be considered to have left the beam. Figure 5b This is a schematic diagram of a change in the number of beams provided by an embodiment of the present application. For example, the beam currently in which the UE is located is beam1. When the signal strength of beam1 is lower than a certain threshold (such as Figure 5b When the signal strength or quality of beam2 is greater than a certain threshold, the UE is considered to be in beam2. When the UE moves to beam3, the signal strength or quality of beam2 will gradually decrease, and the signal strength or quality of beam3 will gradually increase. When the signal strength or quality of beam2 is lower than a certain threshold (such as Figure 5b ), the UE can be considered to have left beam2 and entered beam3. This means that the beam has changed, one beam has been passed through, and the change in the number of beams is 1. Optionally, the certain threshold described in the embodiment of the present application can also be determined according to the distance between the UE and the base station. For example, the closer the distance between the UE and the serving base station, the larger the certain threshold. For example, when the distance between the UE and the base station is less than the distance threshold, the threshold used to measure the signal strength of the beam can be the first beam threshold; when the distance between the UE and the base station is not less than the distance threshold, the threshold used to measure the signal strength of the beam can be the second beam threshold, and the second beam threshold is less than the first beam threshold. Exemplarily, the change in beam quality can be implemented in the following ways:

[0254] 1. The change in beam quality is expressed as the change in the best quality beam received by the UE.

[0255] For example, if the signal strength change of the best quality beam received by the UE within the third duration threshold is less than the first beam change threshold, the UE can relax the measurement.

[0256] 2. The change in beam quality is represented by the change in the N beams with the best quality received by the UE. For example, the change in beam quality can be represented by the average of the changes in the N beams whose beam signal strength received by the UE is greater than a strength threshold.

[0257] The beams for which the beam signal strength received by the UE is greater than the strength threshold are beam1, beam2, and beam3, and N = 3. Therefore, the UE can determine whether to perform measurement relaxation based on whether the average of the change in quality (also referred to as channel strength) of beam1 within the third duration threshold, the change in quality of beam2 within the third duration threshold, and the change in quality of beam3 within the third duration threshold is less than the first beam change threshold.

[0258] For example, the change in beam quality can be expressed as follows:

[0259] mean((B1-B1')+(B2-B2')+(B3-B3')+…)

[0260] Where B1 represents the signal strength of beam 1 received by the UE after the movement, and B1' represents the signal strength of beam 1 received by the UE before the movement. B2 represents the signal strength of beam 2 received by the UE after the movement, and B2' represents the signal strength of beam 2 received by the UE before the movement. B3 represents the signal strength of beam 3 received by the UE after the movement, and B3' represents the signal strength of beam 3 received by the UE before the movement.

[0261] 3. The change in beam quality is represented by the average value of the changes in multiple beams received by the UE.

[0262] The multiple beams shown here can be understood as all beams received by the UE. For a detailed description of this implementation, please refer to the above implementation, and will not be described in detail here.

[0263] 4. The change in beam quality is expressed as the average value of the change in the beam specified by the base station.

[0264] It is understood that the specific description of step 503 can also be referred to Figure 3 or Figure 4 The methods shown are not described in detail here.

[0265] 504. When the RSRP value is not greater than the RSRP threshold, determine whether to perform measurement relaxation according to a change amount of the beam within a fourth duration threshold.

[0266] In an embodiment of the present application, when the RSRP value is not greater than the RSRP threshold, the UE may also first obtain the amount of change in the beam received within the fourth duration threshold, and then determine whether to perform measurement relaxation based on the amount of change in the beam within the fourth duration threshold and the second beam change threshold. Exemplarily, the above step 504 may also be replaced by: when the RSRP value is not greater than the RSRP threshold, determine whether to perform measurement relaxation based on the amount of change in the beam within the fourth duration threshold. Alternatively, when the RSRP value is not greater than the RSRP threshold, determine whether to perform measurement relaxation based on whether the amount of change in the beam within the fourth duration threshold is less than the second beam change threshold. Alternatively, when the RSRP value is greater than the RSRP threshold, determine whether to perform measurement relaxation based on the amount of change in the RSRP value within the fourth duration threshold, etc.

[0267] There are several implementations for step 504:

[0268] 1. When the RSRP value is not greater than the RSRP threshold, if the beam change is less than the second beam change threshold within the fourth duration threshold, it is considered that the UE is in a low mobility state and measurement relaxation can be performed.

[0269] 2. When the RSRP value is not greater than the RSRP threshold, if the beam change amount is less than the second beam change amount threshold within the fourth duration threshold, the UE may choose to relax the measurement.

[0270] 3. When the RSRP value is not greater than the RSRP threshold, and within the fourth duration threshold, if the beam change is not greater than the second beam change threshold, the UE may choose to relax the measurement.

[0271] 4. When the RSRP value is less than the RSRP threshold, if the beam change is less than the second beam change threshold within the fourth duration threshold, the UE may choose to relax the measurement.

[0272] 5. When the RSRP value is not greater than the RSRP threshold, and within the fourth duration threshold, if the beam change is not greater than the second beam change threshold, the UE may choose to relax the measurement.

[0273] It is understandable that the five implementation methods shown above are only examples, and the description of variations of each of the above implementation methods all fall within the protection scope of the embodiments of the present application.

[0274] Optionally, the amount of change in beam with distance within an interval greater than the RSRP threshold is greater than the amount of change in beam with distance within an interval not greater than the RSRP threshold. For an explanation of the RSRP threshold, please refer to Figure 3 or Figure 4 It is understood that the method shown in the embodiment of the present application can also introduce an RSRP floating threshold, or two intervals, or three intervals, or four intervals, etc. For the description of the RSRP threshold, floating threshold, two intervals, three intervals, or four intervals, etc., please refer to the above and will not be repeated here.

[0275] In a possible implementation, the first beam change threshold and the second beam change threshold are the same. For example, the base station can configure an N (number) or Q (quality) and two T cross , such as a smaller T cross1 and a larger T cross2 For ease of description, the following will take the beam variation threshold value N as an example to illustrate the method provided by the embodiment of the present application. Based on the comparison result between the RSRP value of the UE and the RSRP threshold value, the UE can select a smaller T cross1 or a larger T cross2 Determine whether to perform measurement relaxation. For example, if the RSRP value of the UE is greater than the RSRP threshold, cross1 If the beam variation (also called beam variation, etc.) is less than N, the UE can relax the measurement. For another example, if the RSRP value of the UE is not greater than the RSRP threshold, cross2 If the beam change is less than N, the UE can relax the measurement. For example, if the RSRP value of the UE is in the interval [b, a], cross1 If the beam change is less than N, the UE can relax the measurement. For example, if the RSRP value of the UE is in the interval [c, b], cross2 If the change in the beam is less than N, the UE can relax the measurement.

[0276] In another possible implementation, the first beam variation threshold and the second beam variation threshold are different, such as the first beam variation threshold is greater than the second beam variation threshold. For example, the base station can configure two Ns for the UE, such as a larger N1 and a smaller N2, and two T cross , such as a smaller T cross1 and a larger T cross2 It is understood that the specific description of this implementation can be found in Figure 3 The description of the difference between the first duration threshold and the second duration threshold in the method shown, or, refer to Figure 4The description of the difference between the first RSRP change threshold and the second RSRP change threshold in the method shown is not repeated here.

[0277] In some embodiments of the present application, the RSRP threshold may be replaced by a reference signal receiving quality (RSRQ) threshold. For example, whether to perform measurement relaxation may be determined based on the magnitude of the UE's RSRQ and the RSRQ threshold, and the amount of change in the beam within the third duration threshold, or whether to perform measurement relaxation may be determined based on the amount of change in the beam within the fourth duration threshold. Alternatively, measurement relaxation may be performed in combination with RSRP and RSRQ. For specific instructions, reference may be made to the above text, which will not be described in detail here.

[0278] In other embodiments of the present application, the RSRP threshold may be replaced by a distance threshold. When the distance between the UE and the base station is less than the distance threshold, whether to perform measurement relaxation is determined based on the amount of change in the beam within the third duration threshold. For another example, when the distance between the UE and the base station is not less than the distance threshold, whether to perform measurement relaxation is determined based on the amount of change in the beam within the fourth duration threshold.

[0279] It is understood that the specific description of the RSRQ threshold or distance threshold can be referred to above. Figure 3 or Figure 4 The method shown will not be described here in detail.

[0280] The method provided in the embodiment of the present application can determine whether to perform measurement relaxation based on the size of the UE's RSRP value and the RSRP threshold, the size of the UE's RSRQ value and the RSRQ threshold, the size of the UE's distance from the base station and the distance threshold, and changes in the number or quality of beams received by the UE, so that the UE can more reasonably determine whether to perform measurement relaxation.

[0281] Figure 6 This is a flow chart of a relaxation measurement method provided in an embodiment of the present application. Figure 6 As shown, the method includes:

[0282] 601. A base station broadcasts a measurement parameter, where the measurement parameter is used to indicate an RSRP threshold, a first beam variation threshold, and a second beam variation threshold, where the first beam variation threshold is greater than the second beam variation threshold.

[0283] 602. The UE obtains an RSRP value.

[0284] 603. When the RSRP value is greater than the RSRP threshold, determine whether to perform measurement relaxation according to the beam change amount and the first beam change amount threshold.

[0285] For example, for the number of beams, the closer the UE is to the base station within the same time period, the greater the change in the number of beams. For the beam quality, the closer the UE is to the base station within the same time period, the greater the change in the beam quality. Therefore, in this embodiment of the present application, by setting two beam change thresholds, the UE can determine whether to perform measurement relaxation based on any one or more of its distance from the base station, its RSRP value, or its RSRQ value, thereby enabling the UE to perform measurement relaxation more reasonably and effectively.

[0286] Exemplarily, step 603 may be replaced by: when the RSRP value is greater than the RSRP threshold, determining whether to perform measurement relaxation based on the amount of change in the beam within the third duration threshold and the first beam change threshold. Alternatively, when the RSRP value is greater than the RSRP threshold, determining whether to perform measurement relaxation based on whether the amount of change in the beam within the third duration threshold is less than the first beam change threshold. Alternatively, when the RSRP value is not less than the RSRP threshold, determining whether to perform measurement relaxation based on the amount of change in the beam and the first beam change threshold, etc.

[0287] It is understood that the specific description of step 603 can also refer to the above Figures 3 to 5a For example, the description of the beam variation can be found in Figure 5a The method shown.

[0288] 604. When the RSRP value is not greater than the RSRP threshold, determine whether to perform measurement relaxation according to the beam change amount and the second beam change amount threshold.

[0289] Exemplarily, step 604 may be replaced by: if the RSRP value is not greater than the RSRP threshold, determining whether to perform measurement relaxation based on the amount of change in the beam within the fourth duration threshold and the second beam change threshold. Alternatively, if the RSRP value is not greater than the RSRP threshold, determining whether to perform measurement relaxation based on whether the amount of change in the beam within the fourth duration threshold is less than the second beam change threshold. Alternatively, if the RSRP value is greater than the RSRP threshold, determining whether to perform measurement relaxation based on the amount of change in the beam and the second beam change threshold, etc.

[0290] In a possible implementation, the third duration threshold and the fourth duration threshold may be the same.

[0291] In another possible implementation, the third duration threshold and the fourth duration threshold may be different.

[0292] It is understandable that the description of RSRQ and distance threshold etc. can be referred to above and will not be described in detail here.

[0293] The method provided in the embodiment of the present application can determine whether to perform measurement relaxation based on the size of the UE's RSRP value and the RSRP threshold, the size of the UE's RSRQ value and the RSRQ threshold, the size of the UE's distance from the base station and the distance threshold, and changes in the number or quality of beams received by the UE, so that the UE can more reasonably determine whether to perform measurement relaxation.

[0294] It is understood that the various embodiments shown above can be separate embodiments, or different embodiments can be combined. Figures 3 to 6 The method shown can also be implemented in the following ways:

[0295] If the base station only broadcasts the RSRP threshold, the first RSRP change threshold and the second RSRP change threshold, the UE can Figure 3 The method shown in FIG. 1 determines whether to perform measurement relaxation. For example, if the RSRP value is divided into two intervals based on the RSRP threshold, such as the first interval being [b, a] and the second interval being [c, b], the measurement parameters broadcast by the base station may be as shown in Table 2. It is understood that for the sake of simplicity, the following description of the measurement parameters broadcast by the base station uses the first interval being [b, a] and the second interval being [c, b] as an example.

[0297] variable Value <![CDATA[S SearchDeltaP1 ]]> Larger value x1 <![CDATA[S SearchDeltaP2 ]]> Smaller value x2 <![CDATA[T SearchDeltaP ]]> y RSRP interval division a, b, c

[0298] It is understood that x1, x2, and y shown in Table 2 are merely examples. For example, x1 is used only to represent the value of the first RSRP change threshold, x2 is used to represent the value of the second RSRP change threshold, and y represents the value of the duration threshold. x1, x2, and y may vary depending on the table. For example, in Table 3, x1 may be used to represent the value of the first duration threshold, x2 may be used to represent the value of the second duration threshold, and y may be used to represent the value of the RSRP change threshold. Therefore, this should not be understood as limiting the embodiments of the present application, and will not be further elaborated below.

[0299] For Table 2, when the UE measures parameters, the first duration threshold and the second duration threshold are the same.

[0300] If the base station only broadcasts the RSRP threshold, the first duration threshold and the second duration threshold, the UE can Figure 4 The method shown determines whether to perform measurement relaxation. For example, the measurement parameters broadcast by the base station may be as shown in Table 3.

[0303] For Table 3, when the UE measures parameters, the first RSRP change threshold and the second RSRP change threshold are the same.

[0304] If the base station only broadcasts the RSRP threshold, the third duration threshold and the fourth duration threshold, the UE can Figure 5a The method shown determines whether to perform measurement relaxation. For example, the measurement parameters broadcast by the base station may be as shown in Table 4.

[0307] For Table 4, when the UE measures parameters, the first beam change threshold and the second beam change threshold are the same.

[0308] If the base station only broadcasts the RSRP threshold, the first beam change threshold and the second beam change threshold, the UE can Figure 6 The method shown determines whether to perform measurement relaxation. For example, the measurement parameters broadcast by the base station may be as shown in Table 5.

[0311] For Table 5, when the UE measures parameters, the third duration threshold and the fourth duration threshold are the same.

[0312] If the base station broadcasts both the RSRP threshold, the first duration threshold, the second duration threshold, and the first RSRP change threshold and the second RSRP change threshold, the UE may determine whether to perform measurement relaxation based on whether the change in the RSRP value within the first duration threshold is less than the first RSRP change threshold, or based on whether the change in the RSRP value within the second duration threshold is less than the second RSRP change threshold (refer to Figure 3 or Figure 4 For example, the measurement parameters broadcast by the base station may be as shown in Table 6.

[0315] For Table 6, when the UE measures parameters, the first duration threshold and the second duration threshold are different, and the first RSRP change threshold and the second RSRP change threshold are also different.

[0316] If the base station broadcasts the RSRP threshold, the third duration threshold, the fourth duration threshold, and the first beam variation threshold and the second beam variation threshold, the UE may determine whether to perform measurement relaxation based on whether the beam variation within the third duration threshold is less than the first beam variation threshold, or based on whether the beam variation within the fourth duration threshold is less than the second beam variation threshold. For example, the measurement parameters broadcast by the base station may be as shown in Table 7.

[0319] For Table 7, when the UE measures parameters, the third duration threshold and the fourth duration threshold are different, and the first beam change threshold and the second beam change threshold are also different.

[0320] It is understood that whether the first duration threshold is the same as the third duration threshold is not limited in this embodiment of the application. At the same time, whether the second duration threshold is the same as the fourth duration threshold is not limited in this embodiment of the application.

[0321] The base station broadcasts the RSRP threshold, the first RSRP change threshold, the second RSRP change threshold, and the third duration threshold and the fourth duration threshold.

[0324] For Table 8, the first duration threshold and the second duration threshold are the same, and the first beam change amount threshold and the second beam change amount threshold are the same.

[0325] For example, if the RSRP value of the UE is greater than the RSRP threshold, the UE may determine whether to perform measurement relaxation based on a first RSRP change threshold or a change in the beam within a third duration threshold. For another example, if the RSRP value of the UE is not greater than the RSRP threshold, the UE may determine whether to perform measurement relaxation based on a second RSRP change threshold or a change in the beam within a fourth duration threshold.

[0326] Exemplarily, if the UE's RSRP value is greater than the RSRP threshold, the UE needs to determine whether to perform measurement relaxation based on the first RSRP change threshold and the change in the beam within the third duration threshold. For example, if the UE's RSRP value is greater than the RSRP threshold, the change in the RSRP value within the first duration threshold is less than the first RSRP change threshold, and the change in the beam within the third duration threshold is less than the first beam change threshold, the UE performs measurement relaxation. Otherwise, the UE does not perform measurement relaxation.

[0327] Exemplarily, if the RSRP value of the UE is not greater than the RSRP threshold, the UE needs to determine whether to perform measurement relaxation based on a second RSRP change amount and a beam change amount within a fourth duration threshold. For example, if the RSRP value of the UE is not greater than the RSRP threshold, the RSRP change amount within the second duration threshold is less than the second RSRP change amount threshold, and the beam change amount within the fourth duration threshold is less than the second beam change amount threshold, the UE performs measurement relaxation. Otherwise, the UE does not perform measurement relaxation.

[0328] The base station broadcasts the RSRP threshold, the first duration threshold, the second duration threshold, and the third duration threshold and the fourth duration threshold.

[0331] For Table 9, the first RSRP change threshold and the second RSRP change threshold are the same, and the first beam change threshold and the second beam change threshold are the same.

[0332] The base station broadcasts the RSRP threshold, the first duration threshold, the second duration threshold, the first RSRP change threshold, the second RSRP change threshold, and the third duration threshold and the fourth duration threshold. For example, the measurement parameters broadcast by the base station are shown in Table 10.

[0333] Table 10

[0334]

[0335]

[0336] For Table 10, the first beam variation threshold and the second beam variation threshold are the same.

[0337] The base station broadcasts the RSRP threshold, the first duration threshold, the second duration threshold, the first RSRP change threshold, the second RSRP change threshold, and the third duration threshold, the fourth duration threshold, the first beam change threshold, and the second beam change threshold. It is understood that the first duration threshold corresponds to the first RSRP change threshold, the second duration threshold corresponds to the second RSRP change threshold, the third duration threshold corresponds to the first beam change threshold, and the fourth duration threshold corresponds to the second beam change threshold. Exemplarily, the measurement parameters broadcast by the base station are shown in Table 11.

[0340] Exemplarily, when the difference between the first duration threshold and the third duration threshold is less than a preset threshold, or the difference between the second duration threshold and the fourth duration threshold is less than a preset threshold, whether to perform measurement relaxation is determined based on whether the change in the RSRP value of the UE within the first duration threshold is less than the first RSRP change threshold (or the second RSRP change threshold), and whether the change in the beam received by the UE within the third duration threshold is less than the first beam change threshold (or the second beam change threshold). When both meet the low-speed mobility criteria, the UE performs measurement relaxation. Exemplarily, whether to perform measurement relaxation can also be determined based on the maximum value of the first duration threshold and the third duration threshold (or the maximum value of the second duration threshold and the fourth duration threshold). For example, if the maximum value of the first duration threshold and the third duration threshold is the third duration threshold, the UE can determine whether to perform measurement relaxation based on whether the change in the RSRP value within the third duration threshold is less than the first RSRP change threshold, and whether the change in the beam within the third duration threshold is less than the first beam change threshold. In this case, the first RSRP change threshold can be updated proportionally. For example, let's say the first duration threshold is 5 seconds, the first change threshold is 5dB, the third duration threshold is 8 seconds, and the beam change N = 1. Since the maximum of the first and third duration thresholds is the third duration threshold, the first duration threshold needs to be changed from 5 seconds to 8 seconds, and thus the first RSRP change threshold also needs to be changed from 5dB to 8dB. That is, the proportionally changed first RSRP change threshold = 5dB * 8s / 5s = 8dB.

[0341] For example, when the difference between the first duration threshold and the third duration threshold is greater than a preset threshold, or the difference between the second duration threshold and the fourth duration threshold is greater than a preset threshold, whether to measure relaxation can be determined based on the maximum value of the first duration threshold and the third duration threshold (or the maximum value of the second duration threshold and the fourth duration threshold). Accordingly, the corresponding change threshold also needs to be updated proportionally.

[0342] It can be understood that for the relevant descriptions of Tables 2 to 11, reference can be made to the above embodiments, and they will not be described in detail here.

[0343] Generally, RSRP is the linear value of the power of the cell downlink common pilot within the measurement bandwidth (the power on each RE). When there are multiple receiving antennas, the measurement results on the multiple receiving antennas need to be compared, and the reported value should not be lower than the RSRP value corresponding to any branch antenna. Therefore, since the UE with a large number of receiving antennas reports the maximum RSRP value among the multiple receiving antennas, the RSRP value of the UE with more receiving antennas is greater than the RSRP value of the UE with fewer receiving antennas. Therefore, if a 1R UE and a 4R UE share an SSearchThresholdP , or, Redcap UE and legacy UE share one S SearchThresholdP ,1R UE or Redcap UE may receive a very poor RSRP and cannot receive data normally.

[0344] Figure 7 This is a flow chart of a relaxation measurement method provided in an embodiment of the present application. Figure 7 As shown, the method includes:

[0345] 701. A base station broadcasts a measurement parameter, where the measurement parameter indicates a first RSRP threshold and a second RSRP threshold, where the second RSRP threshold is greater than the first RSRP threshold. Correspondingly, a UE receives the measurement parameter.

[0346] It is understood that the relevant description of step 701 can refer to the above Figures 3 to 6 etc., which will not be elaborated here.

[0347] 702. The UE performs measurement relaxation according to the first RSRP threshold or the second RSRP threshold.

[0348] In the embodiment of the present application, the first RSRP threshold and the second RSRP threshold can be used as a not at cell edge criterion. For example, if the RSRP value of the UE is greater than the first RSRP threshold, the UE is considered not at the cell edge and measurement relaxation can be performed. Alternatively, if the RSRP value of the UE is greater than the second RSRP threshold, the UE is considered not at the cell edge and measurement relaxation can be performed.

[0349] Exemplarily, the first RSRP threshold and the second RSRP threshold may be implemented in the following ways:

[0350] 1. Different numbers of receiving antennas correspond to different RSRP thresholds. Alternatively, it can be understood that different transceiver capabilities correspond to different RSRP thresholds. For example, a UE with strong transceiver capabilities can relax measurements based on a first RSRP threshold, while a UE with weak transceiver capabilities can relax measurements based on a second RSRP threshold. For example, when the number of receiving antennas is greater than a preset number, the UE can relax measurements based on the first RSRP threshold. For another example, when the number of receiving antennas is less than or equal to a preset number, the UE can relax measurements based on the second RSRP threshold. The second RSRP threshold is greater than the first RSRP threshold.

[0351] For example, a 1R UE (including a 1R Redcap UE) can perform measurement relaxation based on the second RSRP threshold, a 4R UE can perform measurement relaxation based on the first RSRP threshold, or a 2R UE (including a 2R Redcap UE) can perform measurement relaxation based on the first RSRP threshold.

[0352] Figure 8 The edge areas of 1R UE and 4R UE are shown as examples. Generally, the RSRP value of 4R UE takes the maximum value among 4R UEs, and on average, it is larger than the RSRP value of 1R UE at the same location. Moreover, 4R UE can perform maximum ratio combining because of multiple antennas. Therefore, even if the RSRP values ​​of 1R UE and 4R UE are the same, the SNR of 4R UE is still larger than that of 1R UE, and the bit error rate is lower than that of 1R UE. Therefore, it is unreasonable to use the same RSRP threshold for 1R UE and 4R UE. Through the embodiment of the present application, a separate threshold such as S is configured for 1R UE. SearchThresholdP-1R , and the S SearchThresholdP-1R Greater than the threshold S of 4R UE SearchThresholdP Therefore, 1R UE can better and more reasonably apply the "not at cell edge" criterion.

[0353] 2. Legacy UEs and Redcap UEs correspond to different RSRP thresholds. For example, Redcap UEs may correspond to a second RSRP threshold, and legacy UEs may correspond to a first RSRP threshold, where the second RSRP threshold is greater than the first RSRP threshold.

[0354] 3. Using coverage enhancement and not using coverage enhancement correspond to different RSRP thresholds. For example, if the cell supports coverage enhancement, the UE can use a first RSRP threshold such as S SearchThresholdP-CE If the cell does not support coverage enhancement, the UE may use a second RSRP threshold such as S SearchThresholdP For example, S SearchThresholdP-CE Can be S SearchThresholdP-1R The threshold after adding the coverage enhancement gain provided by the cell.

[0355] It is understandable that the first RSRP threshold shown in the embodiment of the present application can also be replaced by the first RSRQ threshold, and the second RSRP threshold can also be replaced by the second RSRQ threshold. For example, a measurement parameter is received, and the measurement parameter is used to indicate the first RSRQ threshold and the second RSRQ threshold; the measurement is relaxed according to the first RSRQ threshold or the second RSRQ threshold, and the second RSRQ threshold is greater than the first RSRQ threshold. Optionally, the terminal device can also relax the measurement according to the first RSRP threshold and the first RSRQ threshold; or, relax the measurement according to the second RSRP threshold and the second RSRQ threshold, etc. For the specific description of RSRQ, please refer to the above and will not be described in detail here.

[0356] The method provided in the embodiment of the present application effectively improves the situation where the not-at-cell-edge criterion does not take into account the poor coverage of 1R UE, thereby enabling the 1R UE to apply the cell-edge criterion more reasonably.

It is understood that the specific description of the processor and transceiver can also refer to Figure 9 The description of the processing unit and the transceiver unit shown will not be repeated here.

[0447] exist Figure 10 In various implementations of the communication device shown, the transceiver may include a receiver and a transmitter, wherein the receiver is configured to perform a receiving function (or operation) and the transmitter is configured to perform a transmitting function (or operation). The transceiver is configured to communicate with other devices / devices via a transmission medium.

[0448] During the execution of the above method, the process of sending or receiving information (such as measurement parameters, etc.) in the above method can be understood as the process of the processor outputting the above information and the process of the processor receiving the above information as input. When outputting the above information, the processor outputs the above information to the transceiver so that the transceiver can transmit it. After being output by the processor, the above information may also need to undergo other processing before reaching the transceiver. Similarly, when the processor receives the above information as input, the transceiver receives the above information and inputs it into the processor. Optionally, after the transceiver receives the above information, the above information may need to undergo other processing before being input into the processor.

[0449] For the operations such as transmission, sending and receiving involved in the processor, unless otherwise specified, or unless they conflict with their actual functions or internal logic in the relevant descriptions, they can be more generally understood as processor output, reception, input and other operations, rather than the transmission, sending and receiving operations directly performed by the RF circuit and antenna.

[0450] During implementation, the processor may be a processor specifically configured to execute these methods, or may be a processor that executes computer instructions in a memory to execute these methods, such as a general-purpose processor. The memory may be a non-transitory memory, such as a read-only memory (ROM), which may be integrated with the processor on the same chip or disposed on separate chips. The embodiments of the present application do not limit the type of memory or the configuration of the memory and the processor.

[0451] Optionally, the communication device 100 may further include one or more memories 1030 for storing program instructions and / or data. The memory 1030 is coupled to the processor 1020. The coupling in the embodiment of the present application is an indirect coupling or communication connection between devices, units or modules, which can be electrical, mechanical or other forms, and is used for information exchange between devices, units or modules. The processor 1020 may operate in conjunction with the memory 1030. The processor 1020 may execute program instructions stored in the memory 1030. Optionally, at least one of the one or more memories may be included in the processor. For example, the memory 1030 may store measurement parameters, etc.

[0452] The specific connection medium between the transceiver 1010, the processor 1020 and the memory 1030 is not limited in the embodiment of the present application. Figure 10 The memory 1030, the processor 1020 and the transceiver 1010 are connected via a bus 1040. Figure 10The connections between the other components are shown in bold lines, which are only for illustration and are not intended to be limiting. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of illustration, Figure 10 Only one thick line is used in the diagram, but this does not mean that there is only one bus or one type of bus.

[0453] In the embodiments of the present application, the processor may be a general-purpose processor, a digital signal processor, an application-specific integrated circuit, a field programmable gate array or other programmable logic device, a discrete gate or transistor logic device, a discrete hardware component, etc., and may implement or execute the various methods, steps, and logic block diagrams disclosed in the embodiments of the present application. The general-purpose processor may be a microprocessor or any conventional processor, etc. The steps of the methods disclosed in the embodiments of the present application may be directly implemented as being executed by a hardware processor, or may be executed by a combination of hardware and software modules in the processor, etc.

[0454] In the embodiment of the present application, memory may include but is not limited to non-volatile memories such as hard disk drive (HDD) or solid-state drive (SSD), random access memory (RAM), erasable programmable read-only memory (EPROM), read-only memory (ROM) or portable read-only memory (CD-ROM), etc. Memory is any storage medium that can be used to carry or store program code in the form of instructions or data structures and can be read and / or written by a computer (such as the communication device shown in the present application), but is not limited thereto. The memory in the embodiment of the present application can also be a circuit or other arbitrarily capable of realizing a storage function, for storing program instructions and / or data.

[0455] Illustratively, the processor 1020 is primarily used to process communication protocols and communication data, control the entire communication device, execute software programs, and process software program data. The memory 1030 is primarily used to store software programs and data. The transceiver 1010 may include a control circuit and an antenna. The control circuit is primarily used to convert baseband signals into radio frequency signals and process radio frequency signals. The antenna is primarily used to transmit and receive radio frequency signals in the form of electromagnetic waves. Input / output devices, such as a touch screen, display, and keyboard, are primarily used to receive user input and output data to the user.

[0456] When the communication device is powered on, the processor 1020 can read the software program in the memory 1030, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be sent wirelessly, the processor 1020 performs baseband processing on the data to be sent and outputs the baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal and then transmits the radio frequency signal to the outside in the form of electromagnetic waves through the antenna. When data is sent to the communication device, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor 1020. The processor 1020 converts the baseband signal into data and processes the data.

[0457] In another implementation, the RF circuit and antenna may be provided independently of the processor performing baseband processing. For example, in a distributed scenario, the RF circuit and antenna may be remotely arranged independent of the communication device.
