[0039] Embodiments of the present disclosure are described in detail below, and examples of the embodiments 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 disclosure, and should not be construed as limiting the present disclosure.

[0040] With the rapid development of wireless communication technology, the fifth generation of mobile communication technology (5G) is becoming more and more mature in commercial use. The relevant technology defines that the measurement based on the synchronization signal block SSB uses the SSB measurement time configuration (SMTC) to control the reception time position and time length. In the idle state, inactive state or connected state, the user terminal UE needs to perform frequent SSB detection and measurement of the neighboring cells to meet the mobility requirements. Terminal power consumption and measurement timeliness are important indicators that are essential in terminal design.

[0041] Some related technical solutions complete cell detection within the SMTC time window, obtain cell information and timing synchronization relationship, and then receive SSB data according to the cell timing relationship at the next SMTC window to complete the SSB measurement of the cell. However, this type of solution requires two SSB data receptions, which increases the power consumption of the radio frequency (RF) and takes a long time to measure.

[0042] Some other related technical solutions complete the cell detection within the SMTC time window, store the received data, and then intercept the SSB data within the SMTC window according to the cell timing relationship to complete the SSB measurement of the cell. In this type of solution, the SSB measurement reuses the SSB data of the cell detection. Although the measurement time is shortened, the tolerance of the automatic gain control (AGC) of the received data for the detection performance is looser than that of the measurement. There is an unreasonable AGC of the SSB data received during the cell detection process. Directly using the detection data for SSB measurement will affect the SSB measurement accuracy.

[0043] In order to solve the problems in the above-mentioned related technologies, the present disclosure provides a communication control method, which adopts a flexible AGC control strategy. When performing SSB measurement, by judging whether the reception quality of the cell detection data meets the preset requirements, it is decided whether to reuse the cell detection data, while reducing the power consumption of the terminal, the SSB measurement accuracy is guaranteed, and the cell detection and cell measurement process adopts a compact design to shorten the measurement time. In this way, the problems that the cell detection and SSB measurement are completed in different SMTC window periods, the measurement time is too long, the measurement is not timely, and the cell detection and SSB measurement multiplexing data affects the measurement accuracy due to inappropriate AGC can be solved at the same time.

[0044] Figure 1 A flow chart of a communication control method provided by an embodiment of the present disclosure, such as Figure 1 As shown, the communication control method includes steps 101 to 103. For ease of understanding, Figure 2 An example flowchart of a communication control method provided in an embodiment of the present disclosure.

[0045] Step 101: Use a first automatic gain control AGC to receive a first SSB sent by a network device, and perform SSB detection on the network device based on the first SSB.

[0046] In the embodiments of the present disclosure, the method can be applied to chips, terminals, etc. The terminals mainly include smart phones, tablet computers, car terminals, smart home appliances and other terminal devices that can support mobile communications, which are not limited by the present disclosure.

[0047] In the embodiments of the present disclosure, the AGC circuit is an important circuit in the radio receiving device, which is used to ensure the stability of the receiving amplitude. For example, when the signal power amplitude is small, or the signal power amplitude is too large (signal saturation), or there is an uplink high-power time slot transmission, the signal reception quality can be ensured by adjusting the AGC gear.

[0048] In the embodiments of the present disclosure, the network device may refer to a base station (gNB) or a cell within the coverage of a base station network, etc.

[0049] In some embodiments of the present disclosure, the network device mainly refers to a cell adjacent to a terminal, that is, a neighboring cell of the terminal. To meet mobility requirements, the terminal needs to perform frequent SSB detection and measurement of the neighboring cell in an idle state, an inactive state or a connected state.

[0050] In some embodiments of the present disclosure, the terminal may have multiple neighboring cells, and each cell may send multiple SSBs.

[0051] Furthermore, the first SSB is detection data received by the terminal and is used for cell detection. The first AGC is the AGC used by the terminal to receive the first SSB. The first AGC meets the reception quality requirements of the terminal for receiving the first SSB.

[0052] In some embodiments of the present disclosure, the SSB includes a primary synchronization signal (Primary Synchronization Signal, PSS for short) and a secondary synchronization signal (Secondary Synchronization Signal, SSS for short), and the cell detection includes PSS synchronization and SSS synchronization processes.

[0053] In some embodiments of the present disclosure, after receiving the first SSB, the terminal may also cache the first SSB into a memory to support multiplexing of the first SSB.

[0054] In some embodiments of the present disclosure, Figure 2 As shown, the method also includes: determining whether the SSB detection is successful.

[0055] In some embodiments of the present disclosure, when SSB detection fails, step 101 is repeated to receive detection data and perform cell detection until the cell detection succeeds.

[0056] In some embodiments of the present disclosure, a threshold for the number of times detection data is received or the number of times cell detection is repeated is preset. If the preset threshold is exceeded, subsequent SSB measurements will no longer be performed.

[0057] Step 102, when the SSB detection is successful, determine whether the reception quality of the first SSB meets the first preset requirement.

[0058] It is understandable that the first AGC meets the reception quality requirement of the terminal receiving the first SSB, i.e., the detection data, but usually the detection performance has a looser AGC tolerance for the received data than the measurement. Therefore, the reception quality of the first SSB does not necessarily meet the reception quality requirement of the SSB measurement for the received data. If the detection data is used directly for SSB measurement, it will affect the cell measurement accuracy. Therefore, it is necessary to evaluate and judge the reception quality of the first SSB.

[0059] In an embodiment of the present disclosure, whether to reuse the first SSB in the SSB measurement is determined by judging whether the reception quality of the first SSB meets the first preset requirement, such as Figure 2 As shown, whether to reuse the detection data in subsequent cell measurements is determined by judging the reception quality of the detection data.

[0060] In some embodiments of the present disclosure, the first preset requirement may include the received signal strength (Received Signal Strength Indicator, RSSI for short) of the SSS of the first SSB being within a preset received signal strength threshold range, and the reception quality of the first SSB may also be evaluated by other indicators that can reflect the signal reception quality, which is not limited by the present disclosure.

[0061] Step 103: If the reception quality of the first SSB meets the first preset requirement, perform SSB measurement on the network device based on the first SSB.

[0062] In an embodiment of the present disclosure, if the reception quality of the first SSB meets the first preset requirement, it is considered that the reception quality requirement of the first SSB meets the reception quality requirement of the SSB measurement for received data. When performing SSB measurement, the first SSB can be reused, and there is no need to perform SSB reception again, thereby reducing the power consumption overhead of RF reception and shortening the measurement time.

[0063] In some embodiments of the present disclosure, it also includes: if the reception quality of the first SSB does not meet the first preset requirement, using the second AGC to receive the second SSB sent by the network device, and performing SSB measurement on the network device based on the second SSB.

[0064] In an embodiment of the present disclosure, if the reception quality of the first SSB does not meet the first preset requirement, it is considered that the reception quality requirement of the first SSB does not meet the reception quality requirement of the SSB measurement for received data. When performing SSB measurement, the AGC is adjusted and the second AGC is used to receive the second SSB. Based on the second SSB, SSB measurement is performed on the network device to ensure detection accuracy.

[0065] In an embodiment of the present disclosure, the first SSB and the second SSB are SSBs sent by the same network device, and the reception timing and AGC used for reception of the first SSB and the second SSB are different.

[0066] In summary, according to the communication control method proposed in the present invention, a first automatic gain control AGC is used to receive a first SSB sent by a network device, and SSB detection is performed on the network device based on the first SSB; when the SSB detection is successful, it is determined whether the reception quality of the first SSB meets the first preset requirement; if the reception quality of the first SSB meets the first preset requirement, SSB measurement is performed on the network device based on the first SSB, and if the reception quality of the first SSB does not meet the first preset requirement, a second AGC is used to receive a second SSB sent by the network device, and SSB measurement is performed on the network device based on the second SSB. The scheme of the present invention determines whether to reuse SSB detection data when performing SSB measurement on a neighboring cell. When the SSB detection data received by the AGC meets the preset reception quality, the SSB detection data is reused for SSB measurement, otherwise the AGC is adjusted to re-receive the SSB data for SSB measurement, thereby reducing the power consumption of the terminal and ensuring the SSB measurement accuracy.

[0067] based on Figure 1 The embodiment shown, Figure 3 A specific flow chart of a communication control method proposed in the present disclosure is further shown. For ease of understanding, Figure 4 This is a specific flow chart of an example of a communication control method proposed in the present disclosure.

[0068] In some embodiments, the method of the present disclosure is applicable to the cell detection and measurement process in idle state, inactive state and active / connected state. Figure 5 The present invention provides an idle / deactivated cell detection and measurement process. Figure 6 The present disclosure provides a connected cell detection and measurement process.

[0069] refer to Figure 5 On the network side, if Node B sends the idleMeasConfig configuration, the terminal UE calculates the SMTC window time position according to the measurement configuration; in the SMTC window, it receives air interface data, completes the cell detection process, and obtains the frame timing position and cell information; according to the frame timing position of the cell, it intercepts the SSB data in the SMTC window and performs SSB measurement; the SSB measurement result of each I-DRX cycle is smoothed to determine whether the reselection criteria are met; according to the reselection conditions, it is determined whether to initiate a cell reselection request to the network.

[0070] refer to Figure 6, the network side, such as Node B, sends RRC MeasConfig configuration, and the terminal UE calculates the GAP and SMTC window time positions according to the measurement configuration; in the SMTC window, it receives air interface data, completes the cell detection process, and obtains the frame timing position and cell information; according to the frame timing position of the cell, it intercepts the SSB data in the SMTC window and performs SSB measurement; the SSB measurement results of each GAP period are smoothed to determine whether the reporting conditions are met; if the reporting conditions are met, the measurement results are reported to the network according to the measReportConfig requirements.

[0071] It can be understood that in the cell detection and measurement process in the above-mentioned idle state, deactivated state and connected state, the SSB data of the cell detection is reused. Although the measurement time is shortened, there is a problem that the AGC of the SSB data received during the cell detection process is unreasonable, which affects the cell measurement accuracy. The method disclosed in the present invention can be applied to the above-mentioned scenario to flexibly adjust the AGC, thereby shortening the measurement time and ensuring the cell measurement accuracy.

[0072] like Figure 2 As shown, the communication control method includes steps 201-205.

[0073] Step 201: Use a first automatic gain control AGC to receive a first SSB sent by a network device, and perform SSB detection on the network device based on the first SSB.

[0074] In some embodiments, reference Figure 4 , pre-set an initial first AGC, the terminal uses the initial first AGC to receive detection data, the detection data may include SSB data of multiple cells, cache the received detection data into the TBUFF memory, and use the received detection data to perform SSB detection.

[0075] Further, in some embodiments, the initial first AGC may be determined according to the effective range of the RF reception signal amplitude of the terminal or actual measurement experience, for example, the effective range of the first AGC is [20, 90], or the value may be 30, which is not limited in the present disclosure.

[0076] In some embodiments, reference Figure 4 , and also includes: pre-setting a detection data reception times threshold, initializing the detection data reception times count (which can be recorded as RxDataCnt) to 0, and adding 1 to the detection data reception times count each time the detection data is received or each time the detection data storage device is stored, that is, the value of RxDataCnt is added by 1.

[0077] In some embodiments of the present disclosure, a first SSB sent by a network device is received using a first AGC, and SSB detection of the network device based on the first SSB includes: receiving a configuration message sent by the network device, wherein the configuration message includes a first parameter, and the first parameter is used to indicate SSB measurement time configuration SMTC window information; based on the configuration message, determining the time position of the first SMTC window; using the first AGC in the first SMTC window to receive the first SSB, wherein the first SBB includes at least main synchronization signals PSS and SSS; according to the first SSB, performing a synchronization process of PSS and SSS to obtain an identity identification and frame timing synchronization relationship of the network device.

[0078] In some embodiments, reference Figure 4 The terminal's detection process of the cell based on SSB includes: receiving the measurement configuration parameters sent by the cell, calculating the starting time (relative to the serving cell frame timing) and length of the first SMTC window according to the measurement configuration parameters, and the measurement configuration parameters, for example, indicate the time length of a time window for SSB measurement, for example, indicate a time point as the starting time or end time of SSB measurement, etc.

[0079] Furthermore, detection data is received in the first SMTC window, specifically, multiple OFDM symbols are received in the first SMTC window. The detection data may include SSB data of multiple cells, and the PSS and SSS synchronization process is completed according to the SSB data of the cells.

[0080] In some embodiments, the PSS synchronization process includes: generating three groups of local master synchronization signals with group IDs 0, 1, and 2, performing sliding correlation with received data, obtaining correlation peak-to-peak values, determining synchronization point positions based on correlation peaks, and obtaining PSS time domain starting positions.

[0081] In some embodiments, the SSS synchronization process includes: extracting SSS synchronization signal data and correlating it with a locally generated SSS sequence according to the mapping position of the SSS synchronization signal in the SSB, obtaining the peak value of the correlation peak, obtaining the maximum value of the peak value of the correlation peak, determining the cell group identifier, and confirming the cell ID and frame timing synchronization relationship according to the intra-group identifier.

[0082] Step 202, determine the RSSI of the first SSB and / or the SSS correlation peak in the first SSB.

[0083] In some embodiments, the terminal may obtain a peak value of an SSS correlation peak when performing an SSS synchronization process.

[0084] In some embodiments, the first SSB is detection data of a cell received by the terminal, which is received within a first SMTC window, and the RSSI of the received data is the maximum RSSI average power among the RSSI average powers within each OFDM symbol within the first SMTC window.

[0085] Furthermore, the RSSI of the received data can be recorded as Rx_RSSI. The specific calculation formula for the RSSI average power in each OFDM symbol in the first SMTC window is: Rssi(i)=Sum(I-channel data^2+Q-channel data^2) / symbol length. The RSSI of the received data is the maximum value therein, that is, Rx_RSSI=max(Rssi(i)), wherein i is the symbol index, taking values ​​of 0, 1, 2…, 14*first SMTC window length-1, and I-channel data and Q-channel data refer to two channels of IQ modulated data.

[0086] In some embodiments of the present disclosure, the method further includes: determining whether the SSB detection is successful based on the RSSI of the first SSB and / or the SSS correlation peak in the first SSB.

[0087] Step 203, when the first SSB meets the first preset condition, determine that the SSB detection is successful.

[0088] Among them, the first preset condition includes at least one of the following: the SSS correlation peak in the first SSB is greater than or equal to a preset threshold, and the RSSI of the first SSB meets the preset second RSSI threshold range.

[0089] In some embodiments, the method further includes: presetting a preset threshold of the SSS correlation peak and / or presetting a second RSSI threshold range.

[0090] In some embodiments, the second RSSI threshold is the RSSI threshold of the above-mentioned received data. According to the RF reception performance of the terminal and the effective bit width of the received data, the RSSI effective threshold range of the received data can be determined, which is recorded as [Rx_Rssi_Threshold1, Rx_Rssi_Threshold2], where Rx_Rssi_Threshold1 is the first preset threshold of RRSI for received data, and Rx_Rssi_Threshold2 is the second preset threshold of RRSI for received data.

[0091] In some embodiments, the SSS correlation peak threshold when SSB detects a valid cell under different channel environments can be determined by algorithm simulation, and is recorded as Peak_Threshold.

[0092] In some embodiments, the SSS correlation peak is denoted as SSS_CorrPeak, referring to Figure 4, determine whether SSS_CorrPeak is less than the preset threshold Peak_Threshold of the correlation peak. When SSS_CorrPeak is less than the preset threshold Peak_Threshold of the correlation peak, it is considered that the cell detection is successful.

[0093] In some embodiments of the present disclosure, it also includes: determining that the SSB detection fails when the first SSB does not meet the first preset condition.

[0094] In some embodiments, reference Figure 4 , it can be determined that the SSB detection failed only based on the SSS correlation peak being greater than or equal to the preset threshold of the correlation peak, but it is not sufficient to determine the cause of the SSB detection failure. Another judgment is needed to determine whether the RSSI of the received data meets the preset RSSI valid threshold range of the received data.

[0095] Furthermore, the RSSI of the received data is recorded as Rx_RSSI. When Rx_RSSI is greater than the first preset threshold Rx_Rssi_Threshold1 of the received data RRSI and less than the second preset threshold Rx_Rssi_Threshold2 of the received data RRSI, it is considered that the reason for the SSB detection failure is that the SSS does not detect a valid cell, and the measurement result is set to an invalid value, such as 0xFFFF.

[0096] In some embodiments, reference Figure 4 When the RSSI of the received data meets the preset RSSI valid threshold range of the received data, it is considered that the reason for the failure of SSB detection is that the first AGC of the current received data is inappropriate, including that the signal power amplitude is too small, or the signal power amplitude is too large (signal saturation), or there is an uplink high-power time slot transmission, etc.

[0097] Furthermore, in some embodiments, it also includes: adjusting the first AGC, and repeating the above SSB detection step according to the adjusted first AGC until the detection is successful or the detection data reception count RxDataCnt is greater than a preset threshold RxDataCnt_Threshold.

[0098] Step 204: When the SSB detection is successful, determine the received signal strength RSSI of the secondary reference signal SSS in the first SSB.

[0099] In some embodiments, reference Figure 4 , when SSB detection is successful, the symbol position of SSS is determined according to SSS, the data of SSS symbol in the first SMTC window is intercepted, and the RSSI value of SSS is calculated. The RSSI of SSS is recorded as SSS_RSSI. The specific calculation formula is as follows:

[0100] SSS_RSSI = Sum (I data^2 + Q data^2) / symbol length

[0101] Step 205, determining whether the RSSI of the SSS meets a preset first RSSI threshold range.

[0102] In some embodiments, it also includes pre-setting a first RSSI threshold range. Specifically, the first RSSI threshold range is an RSSI threshold range that satisfies the reception quality of SSB measurement. It can be determined by algorithm simulation based on the RF reception performance of the terminal UE and the effective bit width of the received data, as well as the measurement accuracy, and is denoted as [Meas_Rssi_Threshold1, Meas_Rssi_Threshold2], wherein Meas_Rssi_Threshold1 is the first measurement RSSI threshold, and Meas_Rssi_Threshold2 is the second measurement RSSI threshold.

[0103] For further reference, Figure 4 When SSS_RSSI is greater than the first preset RSSI threshold Meas_Rssi_Threshold1 and less than the second preset RSSI threshold Meas_Rssi_Threshold2, the RSSI of SSS meets the preset first RSSI threshold range; when SSS_RSSI is less than the first preset RSSI threshold Meas_Rssi_Threshold1 or greater than the second preset RSSI threshold Meas_Rssi_Threshold2, the RSSI of SSS does not meet the preset first RSSI threshold range.

[0104] Step 206: If the RSSI of the SSS meets the preset first RSSI threshold range, perform SSB measurement on the network device based on the first SSB.

[0105] In some embodiments of the present disclosure, performing SSB measurement on a network device based on a first SSB includes: taking out the first SSB from a memory according to a frame timing synchronization relationship; and performing SSB measurement on the network device based on a configuration message sent by the network device and the first SSB.

[0106] In some embodiments, reference Figure 4 When SSS_RSSI is greater than the first preset RSSI threshold Meas_Rssi_Threshold1 and less than the second preset RSSI threshold Meas_Rssi_Threshold2, the SSB measurement and cell detection sharing data mode is adopted. Figure 7, use the data previously cached in the TBUFF memory, detect the cell synchronization position according to the SSS, intercept the SSB data of each cell in the memory, and perform SSB measurement of each cell according to the measurement configuration and SSB data.

[0107] In some embodiments of the present disclosure, if the RSSI of the SSS does not meet the preset first RSSI threshold range, a second AGC is used to receive a second SSB sent by the network device, and SSB measurement is performed on the network device based on the second SSB.

[0108] In some embodiments of the present disclosure, a second SSB sent by a network device is received using a second AGC, and SSB measurement of the network device is performed based on the second SSB, including: adjusting the first AGC according to the RSSI of the SSS to obtain the second AGC; determining the time position of the second SMTC window based on the configuration message sent by the network device, wherein the time position of the second SMTC window is after the time position of the first SMTC window; and receiving the second SSB sent by the network device using the second AGC in the second SMTC window according to the frame timing synchronization relationship, and SSB measurement of the network device is performed based on the second SSB.

[0109] In some embodiments, reference Figure 4 When SSS_RSSI is less than the first preset threshold Meas_Rssi_Threshold1 of measuring RSSI, or greater than the second preset threshold Meas_Rssi_Threshold2 of measuring RSSI, it is considered that the reception quality of the SSB data received during detection does not meet the measurement requirements, and the detection data cached in TBUFF is not used. The first AGC can be adjusted according to SSS_RSSI to obtain the second AGC. The specific calculation formula is:

[0110] Second AGC = first AGC + delta_AGC_SSS_AGC

[0111] For further reference, Figure 8 , according to the configuration parameters, determine the next SMTC window reception timing position, use the second AGC to receive data in the next SMTC window, obtain the SSB time domain position of each cell in the SMTC window based on the frame timing synchronization relationship of each cell obtained by SSB detection, and then perform SSB measurement on each cell.

[0112] In summary, the communication control method proposed in the present disclosure has the following improvements and beneficial effects:

[0113] 1. Cell measurement can reuse cell detection data to reduce terminal power consumption;

[0114] 2. Adopting flexible AGC control strategy, it solves the problem of multiplexing data of cell detection and SSB measurement, which affects the measurement accuracy due to inappropriate AGC, and improves the cell measurement accuracy;

[0115] 3. The cell detection and cell measurement process adopts a compact design to shorten the measurement time;

[0116] 4. The preset thresholds in the solution can be configured according to specific application scenarios, making the design more flexible.
