Description

Signal measurement method, communication device, chip and module equipment

Technical Field

The present invention relates to the field of communications, and in particular, to a method for measuring a signal, a communication device, a chip, and a module device.

Background

Generally, when cell detection and cell reference signal measurement are performed, a terminal device receives data with a specific length, where the data length needs to ensure that synchronization signals of all cells to be detected or reference signals of all cells to be measured under a target frequency point are effectively included. As shown in fig. 1, when performing measurement, the terminal device may fall at any point within a measurement interval (GAP) because the terminal device cannot know synchronization information of each cell under a target frequency point in advance, and therefore the terminal device generally needs to receive a sufficient data length. A sufficient data length can ensure that synchronization signals or reference signals of all cells can be received in the time period. Although this method can ensure that all valid information is contained, it will bring some extra consumption from the viewpoint of system power consumption.

In order to reduce power consumption of a terminal device, an embodiment of the present application provides a method for measuring a signal, as shown in fig. 3, fig. 3 is a flowchart illustrating a method for receiving a paging message according to an embodiment of the present application. The method for receiving the paging message includes the following steps 301 and 302.

Wherein:

301. and the terminal equipment determines the initial receiving position and the target receiving length based on the signal-to-interference-plus-noise ratio of at least one cell under the target frequency point.

In the embodiment of the application, the target frequency point is a frequency point configured by the network device for the terminal device. The Signal to Interference plus Noise Ratio (SINR) is the Ratio of the received strength of the useful Signal to the received strength of the interfering Signal, and the SINR can be used by the terminal device to determine the Signal quality condition of the current cell. The reception is data of a Specific length, which includes data corresponding to a Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), or a Cell-Specific Reference Signal (CRS), and which is received by the terminal device when Cell detection and measurement of a Cell Reference Signal are performed. The receiving starting position is a time domain position where the terminal device starts to receive data, and the target receiving length refers to a time domain length corresponding to the data received by the terminal device. The target receiving length determined by the terminal equipment is less than or equal to the sufficient receiving length, and the networking mode of the target frequency point is synchronous networking. The sufficient receiving length refers to a length of time required for the terminal device to receive the synchronization signals or the reference signals of all cells within a time period, which can be ensured to receive the synchronization signals or the reference signals of all cells within the time period, because the terminal device cannot know the synchronization information of each cell at a target frequency point in advance when measuring the cell reference signals, and the signals required for measurement may fall at any point within a measurement interval (GAP).

In a possible implementation manner, if the networking mode of the target frequency point is unknown or asynchronous networking is performed, the terminal device may detect the cell under the target frequency point or measure the reference signal of the cell in a sufficient number receiving mode, that is, the target number receiving length is the sufficient number receiving length. Based on the realization mode, when the target frequency point is in an unknown networking mode or is in an asynchronous networking mode, the method is favorable for more accurately detecting the cell under the target frequency point and measuring the reference signal of the cell.

In a possible implementation manner, the specific implementation manner of step 301 may be: the terminal equipment classifies at least one cell based on the SINR of the at least one cell under the target frequency point; the terminal equipment determines a data receiving protection interval and a target synchronous deviation value based on the classification condition of at least one cell under a target frequency point; the terminal device determines a target receiving length based on the receiving guard interval, and determines a receiving start position based on the target synchronization offset value and the target receiving length. As shown in fig. 4, since the determined target receiving length is smaller than the sufficient receiving length, and the target receiving length includes the time domain positions corresponding to the reference signal and the synchronization signal, based on the implementation, it is beneficial to reduce the power consumption of the terminal device.

Optionally, the specific manner of classifying the cells by the terminal device according to the SINR may be as follows: when a cell with SINR greater than a first threshold exists under the target frequency point and a cell with SINR less than or equal to the first threshold exists under the target frequency point, the terminal equipment marks the cell with SINR greater than the first threshold as a credible cell and marks the cell with SINR less than or equal to the first threshold as a cell to be estimated; when the cell with the SINR larger than the first threshold does not exist under the target frequency point, the terminal equipment marks the cell with the synchronization deviation value larger than the second threshold as a suspicious cell, and marks the cell with the synchronization deviation value smaller than or equal to the second threshold as a cell to be estimated.

For example, it is assumed that the target frequency includes four cells, which are a first cell, a second cell, a third cell, and a fourth cell. The SINRs of the first cell and the second cell are greater than a first threshold, and the SINRs of the third cell and the fourth cell are less than the first threshold. And the terminal equipment marks the first cell and the second cell as credible cells and marks the third cell and the fourth cell as cells to be estimated.

For another example, it is assumed that the target frequency point includes four cells, which are a first cell, a second cell, a third cell, and a fourth cell. The SINR of all the cells is smaller than the first threshold, after measuring the synchronization deviation values of the four cells, the terminal device determines that the synchronization deviation value of the first cell is larger than the second threshold, and the synchronization deviation values of the remaining cells are smaller than the second threshold. Therefore, the terminal device marks the first cell as a cell to be estimated, and marks the second cell, the third cell and the fourth cell as suspicious cells.

Further optionally, the first threshold may be obtained by simulating cells in each scene through an algorithm, and the first threshold may be used to determine whether a cell detected through a target frequency point is a cell that actually exists.

Further optionally, when the number of cells with SINR greater than the first threshold at the target frequency point exceeds a third threshold and the first synchronization offset difference is greater than a fourth threshold, the terminal device adjusts the size of the first threshold to the first SINR; the first synchronous offset difference is the maximum value of a plurality of synchronous offset differences, the plurality of synchronous offset differences are absolute values of differences between a synchronous offset value of a target cell and synchronous offset values of a plurality of cells under a target frequency point, the target cell is the cell with the largest SINR under the target frequency point, and the first SINR is the minimum value of SINRs of the cells meeting the condition that the SINR is larger than the first threshold under the target frequency point. Based on the implementation mode, a more appropriate first threshold can be adjusted, and the terminal device can be facilitated to more accurately judge whether the current cell can be marked as a credible cell.

For example, assuming that the number of the third thresholds is 3, it is assumed that five cells are included in the target frequency point, which are a first cell, a second cell, a third cell, a fourth cell, and a fifth cell, respectively. The terminal device determines that the SINR of the first cell, the second cell, the third cell and the fourth cell are all greater than a first threshold, and among the four cells, the SINR of the first cell is the largest, and the SINR of the fourth cell is the smallest. The first cell is the target cell because the SINR of the first cell is the maximum. The terminal equipment subtracts the synchronization deviation value of the target cell from the synchronization deviation values of the second cell, the third cell, the fourth cell and the fifth cell respectively and obtains a plurality of synchronization deviation difference values by taking the absolute value, and the maximum value of the plurality of synchronization deviation difference values is the first synchronization deviation difference value. And determining the SINR of the fourth cell to be the first SINR because the SINR cell of the fourth cell is the minimum SINR value in the cells (namely the first cell, the second cell, the third cell and the fourth cell) meeting the condition that the SINR is greater than the first threshold. Because the number of the cells with the SINR at the target frequency point greater than the first threshold is 4, when the first synchronization offset difference is greater than the fourth threshold, the terminal device adjusts the size of the first threshold to the first SINR. Based on the adjusted first threshold, the terminal device determines that the first cell, the second cell and the third cell are trusted cells, and the fourth cell and the fifth cell are cells to be estimated.

Optionally, the specific implementation manner of the terminal device determining the data receiving guard interval and the target synchronization deviation value based on the classification condition of at least one cell at the target frequency point may be as follows:

when the cell marked as the trusted cell exists under the target frequency point, the terminal device determines that the data receiving protection interval is a first interval, and determines that the target synchronization deviation value is the synchronization deviation value of the cell with the maximum SINR in the cells marked as the trusted cell under the target frequency point.

When the cell marked as the credible cell does not exist and the cell marked as the cell to be estimated exists under the target frequency point, the terminal equipment determines whether the cell marked as the credible cell exists in the cell marked as the cell to be estimated or not; if the cell marked as the cell to be estimated exists in the cells marked as the cells to be estimated, the terminal equipment determines the data receiving protection interval as a second interval and determines the target synchronization deviation value as the synchronization deviation value of the cell with the maximum SINR in the cells to be estimated marked as the cells to be estimated under the target frequency point; if the cell marked as the cell to be estimated does not have the cell marked as the credible cell, the terminal device determines that the data receiving protection interval is the third interval, and determines that the target synchronization deviation value is the synchronization deviation value of the cell with the maximum SINR in the cell marked as the cell to be estimated under the target frequency point.

When all cells under the target frequency point are marked as suspicious cells, the terminal equipment determines whether the suspicious cells under the target frequency point have cells marked as credible cells; if the cells marked as the trusted cells exist in the suspicious cells under the target frequency point, the terminal device determines that the data receiving protection interval is a fourth interval, and determines that the target synchronization deviation value is the synchronization deviation value of the cell with the maximum SINR in the suspicious cells marked as the trusted cells under the target frequency point.

The first interval is smaller than the second interval, the second interval is smaller than the third interval, and the third interval is smaller than the fourth interval. Because the receiving guard interval is used for determining the target receiving length, different target receiving lengths are determined under different conditions based on the implementation mode, so that the terminal equipment can more accurately detect the cell under the target frequency point and measure the reference signal of the cell under different scenes, and meanwhile, the target receiving length is smaller than the sufficient receiving length, so that the power consumption of the terminal equipment is favorably reduced.

For example, it is assumed that the target frequency includes four cells, which are a first cell, a second cell, a third cell, and a fourth cell, respectively, where the first cell and the second cell are marked as cells to be estimated, and the third cell and the fourth cell are marked as suspicious cells. The terminal device will determine whether the first cell and/or the second cell has been marked as a trusted cell. If the first cell and/or the second cell were marked as trusted cells, the terminal device will determine the charging guard interval as the second interval. And if the first cell and/or the second cell are not marked as the credible cell once, the terminal equipment determines that the data receiving protection interval is the third interval.

Further optionally, after marking the cell as the trusted cell, the terminal device stores the reserved data in the device, and the terminal device may determine whether the cell is the trusted cell based on the data. In addition, there are other ways for the terminal device to determine whether the cell is a trusted cell, which is not limited in this embodiment of the present application.

Further optionally, when all cells at the target frequency point are marked as suspicious cells, there is no cell marked as a trusted cell in the suspicious cells at the target frequency point, and the terminal device may detect the cell at the target frequency point or a reference signal of a measurement cell in a full-counting manner, that is, the target counting length is the full-counting length. Based on the implementation mode, the method is beneficial to the terminal equipment to more accurately detect the cell under the target frequency point and measure the reference signal of the cell.

Optionally, the terminal device determines a target receiving length based on the receiving guard interval, and determines a receiving start position based on the target synchronization offset value and the target receiving length. The target length of the credits L, and the starting position of the credits pos _ start, may be calculated according to the following formula:

L＝Len+Sync_Headroom(1)

pos_start＝Syncoffset+delta3-Sync_Headroom(2)

wherein Len is the effective data length of the target signal, Syncoffset is the synchronization offset value, delta3 is the interval between the target signal and the synchronization offset position, and Sync _ Headroom can be calculated by the following formula:

Sync_Headroom＝delta1+delta2+protect_T(3)

wherein, protect _ T is a receiving guard interval, delta1 is an inter-cell synchronization deviation allowed by a synchronization system, and delta2 is a minimum sliding step.

In a possible implementation manner, if the initial receiving position and/or the end receiving position are not in the measurement GAP, the terminal device detects a cell under the target frequency point or a reference signal of the measurement cell based on the sufficient receiving length, and the end receiving position is determined by the initial receiving position and the target receiving length. Because the synchronization signal and the reference signal are certainly in the measurement GAP, if the initial receiving position or the ending receiving position is not in the measurement CAP, it is indicated that an error may occur in the algorithm, so that the method is beneficial for the terminal equipment to more accurately detect the cell under the target frequency point and the reference signal of the measurement cell.

Optionally, the number-receiving ending position is equal to the number-receiving starting position plus the target number-receiving length.

302. And the terminal equipment detects the cell under the target frequency point or the reference signal of the measured cell based on the initial receiving position and the target receiving length.

In a possible implementation manner, when there is no cell marked as a trusted cell in a plurality of cells under the target frequency point, there is at least one cell marked as a cell to be estimated, and there is a cell marked as a trusted cell in the cell marked as the cell to be estimated, the terminal device sets a detection compensation flag for the target frequency point; and when all cells under the target frequency point are marked as the suspicious cells and the cells marked as the credible cells exist in the cells marked as the suspicious cells, the terminal equipment sets a detection compensation mark for the target frequency point.

Optionally, after step 302 is executed, if no cell is detected on the target frequency point with the detection compensation flag set, the terminal device detects a cell under the target frequency point based on the sufficient length of the cell, and clears the cell compensation flag. Based on the implementation mode, the situation that the cell under the target frequency point is not detected due to errors is avoided.

Optionally, after step 302 is executed, if at least one new cell is detected on the target frequency point with the detection compensation flag set, and the maximum value in the SINR of the at least one new cell is smaller than a fifth threshold, the terminal device detects the cell at the target frequency point based on the sufficient length, and clears the cell compensation flag. Illustratively, if three cells, namely a first cell, a second cell and a third cell, are detected before a target frequency point with a detection compensation flag is set, after the detection, the terminal device detects the fourth cell, and since it is not determined whether the fourth cell is a truly existing cell, it is necessary to detect the cell at the target frequency point based on a sufficient length of the received data. Based on the implementation mode, the terminal equipment can more accurately determine whether the detected new cell is a real cell.
