Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a measurement relaxation method of a wireless communication system, a measurement relaxation device of a wireless communication system, a computer-readable storage medium and a terminal device. Background Art

[0002] In order to monitor the communication quality and wireless link quality of the service area and / or neighboring area in real time, the 5G mobile communication terminal needs to continuously perform RRM (Radio Resource Management), RLM (Radio Link Monitoring), BFD (Bidirectional Forwarding Detection), etc. according to the network configuration criteria. These measurements and monitoring are one of the components of terminal power consumption. When the terminal is in a static scene, such as a fixedly deployed IoT terminal, the wireless environment in which the terminal is located changes relatively slowly. The power consumption of the terminal can be reduced by reducing the measurement objects, measurement frequency, measurement reporting frequency, etc. Therefore, how to relax the measurement and monitoring of the terminal is one of the research areas of terminal low power consumption.

[0003] The existing non-connected RRM measurement relaxation scheme usually configures the static scene judgment criteria through system messages. The terminal evaluates whether the static condition is met based on the static scene judgment criteria. If the terminal determines that the static condition is met, the relaxed RRM measurement defined in the protocol is executed. However, the current method for judging whether the terminal is in a static scene is not robust. Summary of the invention

[0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, the first purpose of the present invention is to propose a measurement relaxation method for a wireless communication system, receiving multiple different SS / PBCH blocks sent in different directions by a synchronization signal / physical broadcast channel SS / PBCH burst from a base station; determining a target SS / PBCH block according to a reference signal evaluation parameter of each SS / PBCH block in the SS / PBCH burst; determining a level value of the target SS / PBCH block and a level value of the remaining SS / PBCH blocks according to a signal evaluation parameter of the target SS / PBCH block and the remaining SS / PBCH blocks in the SS / PBCH burst; when the difference between the level value of the target SS / PBCH block and the first reference level value is less than a first threshold value, and the difference between the level value of the remaining SS / PBCH blocks and the corresponding reference level value is less than a corresponding threshold value, determining that the terminal device is in a stationary scene, and performing a relaxation measurement. The measurement relaxation method of the present invention can determine whether the position of the terminal device in multiple SS / PBCH beam directions remains stable, and can more robustly determine whether the terminal device is in a stationary scene.

[0005] A second objective of the present invention is to provide a measurement relaxation device for a wireless communication system.

[0024] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The following describes in detail the measurement relaxation method, apparatus, terminal equipment and medium of a wireless communication system according to an embodiment of the present invention with reference to the accompanying drawings.

[0026] Figure 1 FIG. 1 is a flow chart of a measurement relaxation method for a wireless communication system according to some embodiments of the present invention. Figure 1 The measurement relaxation method of the wireless communication system in the embodiment of the present application may include the following steps:

[0027] S110 , receiving a plurality of different SS / PBCH blocks sent in different directions by a synchronization signal / physical broadcast channel SS / PBCH burst from a base station.

[0028] Specifically, the terminal device can receive multiple SS / PBCH blocks from the base station within the preset evaluation period, and the transmission beams of different SS / PBCH blocks are pointed in different directions. For example, assuming that the preset evaluation period is 100ms, each SS / PBCH burst contains 4 SS / PBCH blocks, the first SS / PBCH burst is received within the first 20ms, the second SS / PBCH burst is received in the second 20ms, and the fifth SS / PBCH burst is received within the fifth 20ms. Among them, the preset evaluation period is calibrated according to the actual working conditions, and no specific restrictions are made here. The time interval of the SS / PBCH blocks received within the evaluation period is not limited.

[0029] S120: Determine a target SS / PBCH block according to a reference signal evaluation parameter of each SS / PBCH block in the SS / PBCH burst.

[0030] Specifically, the terminal device measures each SS / PBCH block in the SS / PBCH burst to obtain the reference signal evaluation parameters of the corresponding SS / PBCH block. For example, by measuring SS-RSRP (Synchronization Signal Reference Signal Received Power), the received power of each SS / PBCH block can be obtained, by measuring SS-RSRQ (Synchronization Signal Reference Signal Received Quality), the received quality of each SS / PBCH block can be obtained, and by measuring SS-SINR (Synchronization Signal-Signal to Interference plus Noise Ratio), the signal-to-noise ratio of each SS / PBCH block can be obtained. The target SS / PBCH block can be determined by comparing the received power, received quality or signal-to-noise ratio of each SS / PBCH block in the SS / PBCH burst.

[0031] S130, determining a level value of the target SS / PBCH block and level values ​​of the remaining SS / PBCH blocks according to reference signal evaluation parameters of the target SS / PBCH block and the remaining SS / PBCH blocks in the SS / PBCH burst.

[0032] Specifically, the remaining SS / PBCH blocks in the SS / PBCH burst may be SS / PBCH blocks adjacent to the target SS / PBCH block, or may be SS / PBCH blocks not adjacent to the target SS / PBCH block, or may be multiple SS / PBCH blocks in the SS / PBCH burst. For example, assuming that the second SS / PBCH block in the SS / PBCH burst is the target SS / PBCH block, then the remaining SS / PBCH blocks in the SS / PBCH burst may be blocks adjacent to the second SS / PBCH block, such as the first SS / PBCH block or the third SS / PBCH block; the remaining SS / PBCH blocks in the SS / PBCH burst may also be SS / PBCH blocks not adjacent to the second SS / PBCH block, such as the fourth SS / PBCH block; the remaining SS / PBCH blocks in the SS / PBCH burst may also be multiple SS / PBCH blocks in the SS / PBCH burst, such as the third SS / PBCH block and the fourth SS / PBCH block.

[0033] When the reference signal evaluation parameters include received power, SS-RSRP measurement is performed on the target SS / PBCH block and the remaining SS / PBCH blocks to obtain the received powers of the target SS / PBCH block and the remaining SS / PBCH blocks. The received powers of the target SS / PBCH block and the remaining SS / PBCH blocks are filtered and processed respectively to obtain relatively stable level values ​​of the target SS / PBCH block and the remaining SS / PBCH blocks.

[0034] It should be noted that filtering and other processing are performed on the receiving power of the target SS / PBCH block and the remaining SS / PBCH blocks to obtain relatively stable level values ​​of the target SS / PBCH block and the remaining SS / PBCH blocks, which are methods defined by the 3GPP (3rd Generation Partnership Project) standard.

[0035] S140, when the difference between the level value of the target SS / PBCH block and the first reference level value is less than the first threshold, and the difference between the level values ​​of the remaining SS / PBCH blocks and the corresponding reference level values ​​is less than the corresponding threshold, it is determined that the terminal device is in a stationary scene and a relaxed measurement is performed.

[0036] Specifically, after obtaining the level value of the target SS / PBCH block and the level values ​​of the remaining SS / PBCH blocks, determine whether the level value of the target SS / PBCH block and the level values ​​of the remaining SS / PBCH blocks meet the preset conditions. If the level value of the target SS / PBCH block and the level value of the remaining SS / PBCH blocks both meet the preset conditions, it is determined that the terminal device is in a static scene, and the terminal device can perform relaxed measurement at this time; otherwise, it is determined that the terminal device is not in a static scene, and the terminal device cannot perform relaxed measurement at this time.

[0037] In the following description, the remaining SS / PBCH block is taken as an example to be a block adjacent to the target SS / PBCH block. For example, the target SS / PBCH block is the second block in the SS / PBCH burst, which is recorded as SS / PBCH#N. 1 The remaining SS / PBCH block is the third block in the SS / PBCH burst, denoted as SS / PBCH#N 2 , but not as a limitation of the present invention.

[0038] For example, the target SS / PBCH block (SS / PBCH#N 1 ) must satisfy the following formula:

[0039] |Qrxlevmeas_N 1 -Qrxlevmeas RefStationary _N 1 | <SSearchDeltaP-Stationary 1

[0040] Among them, Qrxlevmeas_N 1 Indicates from SS / PBCH#N 1 The measured current level value, Qrxlevmeas RefStationary _N 1 Indicates from SS / PBCH#N 1 The first reference level value measured is the value from SS / PBCH#N in the current evaluation period. 1 Measured by Qrxlevmeas_N 1 For example, the level value of any level other than SS / PBCH#N in the current evaluation period 1 The first level value measured is not limited here. SSearchDeltaP-Stationary 1 Indicates the first threshold, which needs to be calibrated according to actual conditions and is not specifically limited here.

[0041] The remaining SS / PBCH blocks (SS / PBCH#N 2 ) must satisfy the following formula:

[0042] |Qrxlevmeas_N 2 -Qrxlevmeas RefStationary _N 2 | <SSearchDeltaP-Stationary 2

[0043] Among them, Qrxlevmeas_N 2 Indicates from SS / PBCH#N 2 The measured current level value, Qrxlevmeas RefStationary _N 2 Indicates from SS / PBCH#N 2 The corresponding reference level value measured is the value from SS / PBCH#N in the current evaluation period. 2 Measured by Qrxlevmeas_N 2 For example, the level value of any level other than SS / PBCH#N in the current evaluation period 2 The first level value measured is not limited here. SSearchDeltaP-Stationary 2 Indicates SS / PBCH#N 2 The corresponding threshold needs to be calibrated according to the actual situation, and no specific restrictions are made here.

[0044] If the level value of the target SS / PBCH block and the level values ​​of the remaining SS / PBCH blocks both satisfy the above formula, it means that the level values ​​received by the terminal device from the two different SS / PBCH blocks are relatively stable, and it is determined that the terminal device is in a stationary scene, and the terminal device can perform relaxed measurement at this time. If the level value of the target SS / PBCH block does not satisfy the above formula, or the level values ​​of the remaining SS / PBCH blocks do not satisfy the above formula, or the level value of the target SS / PBCH block and the level values ​​of the remaining SS / PBCH blocks do not satisfy the above formula, it means that the level values ​​received by the terminal device from the two different SS / PBCH blocks are not stable, and it is determined that the terminal device is not in a stationary scene, and the terminal device cannot perform relaxed measurement at this time.

[0045] In the related art, when judging whether a terminal device is in a stationary scene based on the stability of the signal strength received from a single SS / PBCH beam or the stability of the average value of the signal strength received from several SS / PBCH beams, the strength of the signal received from a single SS / PBCH beam during the movement of the terminal device may be similar, or the average value of the signal strength received from several SS / PBCH beams may not change significantly, which may cause the terminal device to be unable to robustly judge whether the terminal device is in a stationary scene, resulting in a decrease in the quality of the signal received by the terminal device, affecting the user experience. The present invention judges whether the terminal is in a stationary scene based on the stability of the signal strength received from the strongest SS / PBCH beam and the stability of the signal strength received from the remaining SS / PBCH beams (such as the SS / PBCH beam adjacent to the strongest SS / PBCH beam), and can determine whether the position of the terminal device in the directions of multiple SS / PBCH beams remains stable. In this way, it can more robustly judge whether the terminal device is in a stationary scene, thereby improving the signal quality received by the terminal device and improving the user experience.

[0046] In some embodiments, the reference signal evaluation parameter includes reception quality, and the above method also includes: when the difference between the reception quality of the target SS / PBCH block and the first reference value is less than a second threshold, and the difference between the reception quality of the remaining SS / PBCH blocks and the corresponding reference value is less than the corresponding threshold, determining that the terminal device is in a stationary scene.

[0047] Specifically, when the reference signal evaluation parameters include reception quality, SS-RSRQ measurement is performed on the target SS / PBCH block and the remaining SS / PBCH blocks to obtain the reception quality of the target SS / PBCH block and the remaining SS / PBCH blocks. If the reception quality of the target SS / PBCH block and the reception quality of the remaining SS / PBCH blocks both meet the stability conditions, it means that the reception quality received by the terminal device from these two or more different SS / PBCH blocks is relatively stable, then it is determined that the terminal device is in a stationary scenario, and the terminal device can perform relaxed measurement at this time.

[0048] In the following embodiments, the remaining SS / PBCH blocks are taken as a block adjacent to the target SS / PBCH block. For example, the target SS / PBCH block is the second block in the SS / PBCH burst, which is recorded as SS / PBCH#N. 1 The remaining SS / PBCH block is the third block in the SS / PBCH burst, denoted as SS / PBCH#N 2 , but not as a limitation of the present invention.

[0049] For example, the target SS / PBCH block (SS / PBCH#N 1 ) reception quality must satisfy the following formula:

[0050] |Quality_N 1 -Quality RefStationary _N 1 | <SSearchDeltaP-Stationary 3

[0051] Among them, Quality_N 1 Indicates from SS / PBCH#N 1 The current reception quality measured, Quality RefStationary _N 1 Indicates from SS / PBCH#N 1 The first reference value measured is the value from SS / PBCH#N in the current evaluation period. 1 Measured by dividing Srxlev_N 1 For example, any value other than SS / PBCH#N in the current evaluation period 1 The first value measured is not limited here, SSearchDeltaP-Stationary 3 It represents the second threshold value, which needs to be calibrated according to the actual situation and is not specifically limited here.

[0052] The remaining SS / PBCH blocks (SS / PBCH#N 2 ) reception quality must satisfy the following formula:

[0053] |Quality_N 2 -Quality RefStationary _N 2 | <SSearchDeltaP-Stationary 4

[0054] Among them, Quality_N 2 Indicates from SS / PBCH#N 2 The measured current acceptance quality, Quality RefStationary _N 2 Indicates from SS / PBCH#N 2 The corresponding reference value measured is the value from SS / PBCH#N in the current evaluation period. 2 Measured except Quality_N 2 For example, any value other than SS / PBCH#N in the current evaluation period 2 The first value measured, no specific restrictions are imposed here, SSearchDeltaP-Stationary 4 Indicates SS / PBCH#N 2The corresponding threshold needs to be calibrated according to the actual situation, and no specific restrictions are made here.

[0055] If the reception quality of the target SS / PBCH block and the reception quality of the remaining SS / PBCH blocks both satisfy the above formula, it means that the reception quality received by the terminal device from these two different SS / PBCH blocks is relatively stable, and it is determined that the terminal device is in a stationary scene, and the terminal device can perform relaxed measurement at this time. If the reception quality of the target SS / PBCH block does not satisfy the above formula, or the reception quality of the remaining SS / PBCH blocks does not satisfy the above formula, or the reception quality of the target SS / PBCH block and the reception quality of the remaining SS / PBCH blocks do not satisfy the above formula, it means that the reception quality received by the terminal device from these two different SS / PBCH blocks is not stable, and it is determined that the terminal device is not in a stationary scene, and the terminal device cannot perform relaxed measurement at this time.

[0056] In some embodiments, the reference signal evaluation parameter includes a signal-to-noise ratio, and the above method further includes: when the difference between the signal-to-noise ratio of the target SS / PBCH block and the first reference signal-to-noise ratio is less than a third threshold, and the difference between the signal-to-noise ratio of the remaining SS / PBCH blocks and the corresponding reference signal-to-noise ratio is less than the corresponding threshold, determining that the terminal device is in a stationary scene.

[0057] Specifically, when the reference signal evaluation parameters include the signal-to-noise ratio, the SS-SINR measurement is performed on the target SS / PBCH block and the remaining SS / PBCH blocks to obtain the signal-to-noise ratio of the target SS / PBCH block and the remaining SS / PBCH blocks. If the signal-to-noise ratio of the target SS / PBCH block and the signal-to-noise ratio of the remaining SS / PBCH blocks both meet the stability condition, indicating that the signal-to-noise ratios received by the terminal device from these two or more different SS / PBCH blocks are relatively stable, it is determined that the terminal device is in a stationary scenario, and the terminal device can perform relaxed measurement at this time.

[0058] In the following embodiments, the remaining SS / PBCH blocks are taken as a block adjacent to the target SS / PBCH block. For example, the target SS / PBCH block is the second block in the SS / PBCH burst, which is recorded as SS / PBCH#N. 1 The remaining SS / PBCH block is the third block in the SS / PBCH burst, denoted as SS / PBCH#N 2 , but not as a limitation of the present invention.

[0059] For example, the target SS / PBCH block (SS / PBCH#N 1 ) must satisfy the following formula:

[0060] |SINR_N 1 -SINR RefStationary_N 1 | <SSearchDeltaP-Stationary 5

[0061] Among them, SINR_N 1 Indicates from SS / PBCH#N 1 The measured current signal-to-noise ratio, SINR RefStationary _N 1 Indicates from SS / PBCH#N 1 The first reference signal-to-noise ratio measured is the signal-to-noise ratio from SS / PBCH#N in the current evaluation period. 1 The measured SINR_N 1 Any signal-to-noise ratio other than SS / PBCH#N in the current evaluation period, for example 1 The first signal-to-noise ratio measured is not limited here, SSearchDeltaP-Stationary 5 It represents the third threshold value, which needs to be calibrated according to the actual situation and is not specifically limited here.

[0062] The remaining SS / PBCH blocks (SS / PBCH#N 2 ) must satisfy the following formula:

[0063] |SINR_N 2 -SINR RefStationary _N 2 | <SSearchDeltaP-Stationary 6

[0064] Among them, SINR_N 2 Indicates from SS / PBCH#N 2 The measured current signal-to-noise ratio, SINR RefStationary _N 2 Indicates from SS / PBCH#N 2 The corresponding reference signal-to-noise ratio measured is the signal from SS / PBCH#N in the current evaluation period. 2 The measured SINR_N 2 Any signal-to-noise ratio other than SS / PBCH#N in the current evaluation period, for example 2 The first signal-to-noise ratio measured is not limited here, SSearchDeltaP-Stationary 6 Indicates SS / PBCH#N 2 The corresponding threshold needs to be calibrated according to the actual situation, and no specific restrictions are made here.

[0065] If the signal-to-noise ratio of the target SS / PBCH block and the signal-to-noise ratio of the remaining SS / PBCH blocks both satisfy the above formula, it means that the signal-to-noise ratios received by the terminal device from the two different SS / PBCH blocks are relatively stable, and it is determined that the terminal device is in a stationary scene, and the terminal device can perform relaxed measurement at this time. If the signal-to-noise ratio of the target SS / PBCH block does not satisfy the above formula, or the signal-to-noise ratio of the remaining SS / PBCH blocks does not satisfy the above formula, or the signal-to-noise ratio of the target SS / PBCH block and the signal-to-noise ratio of the remaining SS / PBCH blocks do not satisfy the above formula, it means that the signal-to-noise ratios received by the terminal device from the two different SS / PBCH blocks are not stable, and it is determined that the terminal device is not in a stationary scene, and the terminal device cannot perform relaxed measurement at this time.

[0066] In summary, the reference signal evaluation parameter may be one or more of the received power (level value), received quality, and signal-to-noise ratio. When the reference signal evaluation parameter includes received power, the level value of the target SS / PBCH block and the level values ​​of the remaining SS / PBCH blocks are obtained. If the level value of the target SS / PBCH block and the level values ​​of the remaining SS / PBCH blocks both meet the stability condition, it means that the level values ​​received by the terminal device from the two or more different SS / PBCH block transmission beams are relatively stable, and it is determined that the terminal device is in a stationary scene, at which point the terminal device can perform a relaxed measurement. When the reference signal evaluation parameter includes received quality or signal-to-noise ratio, the received quality of the target SS / PBCH block and the remaining SS / PBCH blocks, or the signal-to-noise ratio of the target SS / PBCH block and the remaining SS / PBCH blocks, is obtained. When the corresponding stability condition is met, it can be determined that the terminal device is in a stationary scene, at which point the terminal device can perform a relaxed measurement. It should be noted that when the reference signal evaluation parameters include multiple ones of reception power, reception quality, and signal-to-noise ratio, the target SS / PBCH block and the remaining SS / PBCH blocks are required to meet the corresponding stability conditions at the same time to determine that the terminal device is in a stationary scene. If any reference signal evaluation parameter does not meet the corresponding stability conditions, it is determined that the terminal device is not in a stationary scene.

[0067] In this way, multiple reference signal evaluation parameters can be combined to more robustly determine whether the terminal device is in a static scene from multiple angles, thereby improving the signal quality received by the terminal device and improving the user experience.

[0068] In some embodiments, the target SS / PBCH block is determined based on the reference signal evaluation parameters of each SS / PBCH block in the SS / PBCH burst, including: taking the SS / PBCH block corresponding to the maximum value of multiple reference signal evaluation parameters as the target SS / PBCH block.

[0069] Specifically, the reference signal evaluation parameters include received power (level value), received quality and signal-to-noise ratio. By comparing one or more of the received power, received quality and signal-to-noise ratio of each SS / PBCH block in the SS / PBCH burst, the target SS / PBCH block can be identified.

[0070] As an example, SS-RSRP measurement is performed on each SS / PBCH block in the SS / PBCH burst to obtain the received power of the corresponding SS / PBCH block, and the received power of the SS / PBCH block is processed to obtain the level value of the SS / PBCH block. For example, the SS-RSRP measurement is performed on the first SS / PBCH block to obtain a level value of -100dBm for the first SS / PBCH block, the SS-RSRP measurement is performed on the second SS / PBCH block to obtain a level value of -98dBm for the second SS / PBCH block, the SS-RSRP measurement is performed on the third SS / PBCH block to obtain a level value of -101dBm for the third SS / PBCH block, and the SS-RSRP measurement is performed on the fourth SS / PBCH block to obtain a level value of -102dBm for the fourth SS / PBCH block. After comparison, the corresponding level value obtained after the SS-RSRP measurement of the second SS / PBCH block is the largest, so the second SS / PBCH block is the target SS / PBCH block.

[0071] As another example, SS-RSRQ measurement is performed on each SS / PBCH block in the SS / PBCH burst to obtain the reception quality of the corresponding SS / PBCH block. For example, SS-RSRQ measurement is performed on the first SS / PBCH block to obtain a reception quality of 2 dB for the first SS / PBCH block, SS-RSRQ measurement is performed on the second SS / PBCH block to obtain a reception quality of 3 dB for the second SS / PBCH block, SS-RSRQ measurement is performed on the third SS / PBCH block to obtain a reception quality of 1 dB for the third SS / PBCH block, and SS-RSRQ measurement is performed on the fourth SS / PBCH block to obtain a reception quality of 1 dB for the fourth SS / PBCH block. After comparison, the reception quality of the corresponding SS / PBCH block obtained after SS-RSRQ measurement of the second SS / PBCH block is the best, and the second SS / PBCH block is the target SS / PBCH block.

[0072] As another example, the SS-SINR measurement is performed on each SS / PBCH block in the SS / PBCH burst to obtain the signal-to-noise ratio of the corresponding SS / PBCH block. For example, the SS-SINR measurement is performed on the first SS / PBCH block to obtain a signal-to-noise ratio of 6dB for the first SS / PBCH block, the SS-SINR measurement is performed on the second SS / PBCH block to obtain a signal-to-noise ratio of 7dB for the second SS / PBCH block, the SS-SINR measurement is performed on the third SS / PBCH block to obtain a signal-to-noise ratio of 5dB for the third SS / PBCH block, and the SS-SINR measurement is performed on the fourth SS / PBCH block to obtain a signal-to-noise ratio of 5dB for the fourth SS / PBCH block. After comparison, the corresponding SS / PBCH block obtained after the SS-SINR measurement of the second SS / PBCH block has the best reception quality, so the second SS / PBCH block is the target SS / PBCH block.

[0073] In some embodiments, the above method also includes: determining that the terminal device is in an idle state.

[0074] Specifically, when the terminal device is inactive for a long time, in order to save power and network resources, the RRC (Radio Resource Control) connection may be released to put the terminal device into an idle state. Therefore, after the terminal device successfully resides in the cell, if it is detected that the terminal device releases the RRC connection, it is determined that the terminal device is in an idle state. After determining that the terminal device is in an idle state, it can be determined whether the terminal device is in a stationary scenario based on the reference signal evaluation parameters of the target SS / PBCH block and the remaining SS / PBCH blocks in the SS / PBCH burst.

[0075] As a specific example, the measurement relaxation method of the wireless communication system includes:

[0076] S201, terminal device.

[0077] S202, network equipment.

[0078] Specifically, the network device can be a router, a switch or a gateway, etc., which is used to send static scene judgment criteria through system messages after the terminal device successfully resides in the cell, such as the evaluation period, the first threshold, the second threshold, the third threshold and the corresponding thresholds of the remaining SS / PBCH blocks under different reference signal evaluation parameters.

[0079] S203, the cell residency is successful.

[0080] When a terminal device enters a new cell during mobility, completes the communication connection with the cell, and completes the necessary authentication and authorization, it is determined that the cell residency is successful.

[0081] S204, determine whether the terminal device is in an idle state, if yes, execute S205; otherwise, do not execute S205.

[0082] After the terminal device successfully resides in the cell, if it is detected that the terminal device releases the RRC connection, it is determined that the terminal device is in the idle state, otherwise it is determined that the terminal device is not in the idle state.

[0083] S205, determine whether the terminal device is in a static scene, if yes, execute S206; otherwise, continue to execute S205.

[0084] Taking the reference signal evaluation parameters including received power as an example, SS-RSRP is measured and processed for the target SS / PBCH block and the remaining SS / PBCH blocks to obtain the level values ​​of the target SS / PBCH block and the remaining SS / PBCH blocks. If the level value of the target SS / PBCH block and the level value of the remaining SS / PBCH blocks both meet the stability condition, it is determined that the terminal device is in a stationary scene and S206 is executed, otherwise S205 is continued.

[0085] S206, performing a relaxation measurement, and continuing to execute S205 under the relaxation measurement to determine whether the terminal device is in a stationary scene.

[0086] In summary, judging whether the terminal is in a stationary scene based on the stability of the signal strength received from the strongest SS / PBCH beam and the remaining SS / PBCH beams (such as the SS / PBCH beams adjacent to the strongest SS / PBCH beam) can determine whether the position of the terminal device in multiple SS / PBCH beam directions remains stable; at the same time, combining multiple reference signal evaluation parameters can more robustly determine whether the terminal device is in a stationary scene from multiple angles. In this way, it is possible to more robustly determine whether the terminal device is in a stationary scene, thereby improving the signal quality received by the terminal device and improving the user experience.

The control module 340 is used to determine that the terminal device is in a stationary scene and perform relaxation measurement when the difference between the level value of the target SS / PBCH block and the first reference level value is less than the first threshold value, and the difference between the level value of the remaining SS / PBCH blocks and the corresponding reference level value is less than the corresponding threshold value.

[0090] In some embodiments, the reference signal evaluation parameters include reception quality, and the control module 340 is also used to determine that the terminal device is in a stationary scenario when the difference between the reception quality of the target SS / PBCH block and the first reference value is less than a second threshold, and the difference between the reception quality of the remaining SS / PBCH blocks and the corresponding reference value is less than the corresponding threshold.
