Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a cell measurement method, apparatus and mobile terminal. Background Technology

[0002] In communication systems, neighboring cells are short for adjacent cells. To ensure that User Equipment (UE) can smoothly hand over between adjacent cells, neighboring cell configuration is required between the source base station and the destination base station.

[0003] Fifth-generation (5G) mobile communication systems operate at higher frequencies, have smaller coverage radii than 4G, and require more base stations. This results in a significantly increased number of neighboring cells and beamforming in 5G. In complex network coverage scenarios, the even denser 5G base stations further increase the number of cells, leading to a substantial increase in the number of neighboring cells that the user needs to measure.

[0004] The primary purpose of neighbor cell measurements is cell handover. At the cell edge, efficient cell handover requires reporting measurement results as quickly as possible so that the UE can camp on the most suitable cell. Handover based on Reference Signal Received Power (RSRP) is the most commonly used handover strategy.

[0005] However, due to the small coverage area of ​​5G cells, the large number of neighboring cells, and the multiple beams in each cell, the UE needs to measure a large number of neighboring cells when performing cell handover based on the RSRP handover strategy. The measurement efficiency is low, so the neighboring cell measurement feedback time is long, which delays the measurement report reporting time. As a result, the UE is still camped in the source cell at the cell edge and fails to hand over to the target cell, which affects the UE's service traffic. Summary of the Invention

[0006] The purpose of this invention is to provide a cell measurement method, device, and mobile terminal, which solves the problem of low measurement efficiency caused by the large number of neighboring cells in RSRP-based cell handover scenarios.

[0112] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0113] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0114] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0115] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0116] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0117] like Figure 1 As shown, an embodiment of the present invention provides a cell measurement method, comprising:

[0118] Step 101: Based on the received time-domain data, obtain M sequence groups and the physical cell identifier (PCI) corresponding to each sequence group; wherein, each sequence group includes a primary synchronization signal (PSS) sequence and a secondary synchronization signal (SSS) sequence.

[0119] Step 102: Obtain the Reference Signal Received Power (RSRP) of each SSS sequence in the M sequence groups, and determine the PCIs corresponding to the N SSS sequences whose RSRP is greater than or equal to a preset threshold as target PCIs, and obtain N target PCIs; wherein, N is less than or equal to M.

[0120] In this step, time-domain data of the SSS sequence can be extracted based on the location of each sequence group to measure the RSRP of the SSS sequence. Then, by comparing the RSRP values ​​of each sequence group with the measurement threshold (i.e., the preset threshold), N sequence groups that meet the measurement threshold are selected. In this way, the cell range that the UE needs to measure can be narrowed down, improving measurement efficiency.

[0121] The specific process for obtaining the RSRP of the SSS sequence in this step is as follows:

[0122] First, the time-domain data of the extracted SSS sequence is converted into frequency-domain data. Then, the channel estimate (e.g., channel estimate denoted by H) is calculated based on the frequency-domain data and the local SSS sequence. The channel estimate H is converted into a time-domain channel estimate. The total H values ​​are summed to obtain the total power. The noise power is obtained by summing the H values ​​within the noise window. Finally, the noise power is subtracted from the total power of H and then converted into a DB value to obtain the RSRP of the SSS.

[0123] In the above steps, time-domain data is used to search for PSS and SSS sequences, calculate the corresponding physical cell identifier, and measure the neighboring cell channel quality. This allows for the selection of sequence groups that meet the conditions based on the measurement threshold, thus narrowing the measurement range of the UE and improving measurement efficiency.

[0124] Step 103: Obtain the measurement result information corresponding to each target PCI based on the PSS sequence corresponding to each target PCI.

[0125] In this embodiment, the PSS sequence and SSS sequence, as well as the corresponding PCI, are obtained by receiving time-domain data. The PCI that meets the conditions is then selected for measurement, which reduces the number of cells that need to be measured. This reduces the measurement time under a large number of neighboring cells in 5G, improves the handover performance, and enables the UE to quickly enter the handover state.

[0126] Optionally, the step of obtaining M sequence groups and the physical cell identifier (PCI) corresponding to each sequence group based on the received time-domain data includes:

[0127] (i) Obtain at least one PSS sequence based on the received time-domain data.

[0128] In this step, PSS sequences can be searched using the received time-domain data. Then, based on the attribute values ​​of the searched PSS sequences, the obtained PSS sequences can be initially filtered, thereby narrowing the measurement range and improving cell handover efficiency.

[0129] (ii) According to the attribute values ​​of the at least one PSS sequence in descending order, obtain the top M PSS sequences and the PSS sequence position corresponding to each PSS sequence.

[0130] It should be noted that the attribute value of the PSS sequence here can be the correlation value of the PSS sequence.

[0131] (iii) Based on each of the M PSS sequence positions, obtain the SSS sequence corresponding to each PSS sequence to generate M sequence groups.

[0132] In this step, based on each of the M PSS sequence positions, the SSS sequence corresponding to each PSS sequence is obtained, which may specifically include:

[0133] (1) Based on the M PSS sequence positions, determine the SSS sequence position corresponding to each PSS sequence position.

[0134] In this step, based on each PSS sequence position, the corresponding SSS sequence position can be calculated. Specifically, it can be calculated using the following formula:

[0135] P SSS =P PSS +2L;

[0136] Among them, P SSS P represents the position of the SSS sequence. PSS The position of the PSS sequence is indicated, and L represents the length of the time-domain data per symbol.

[0137] (2) Obtain the SSS sequence corresponding to the position of the SSS sequence.

[0138] This step may specifically include: obtaining at least one first SSS sequence related to the position of the SSS sequence; and determining the first SSS sequence with the largest attribute value among the at least one first SSS sequences as the SSS sequence corresponding to the position of the SSS sequence.

[0139] It should be noted that the attribute value of the SSS sequence here can be the correlation value of the SSS sequences. Specifically, the correlation of the first SSS sequence can be calculated by traversing it, and then the first SSS sequence with the highest correlation can be selected as the SSS sequence corresponding to that position.

[0140] (iv) Determine the PCI corresponding to each sequence group based on the PSS sequence and the SSS sequence in each sequence group.

[0141] In this step, PCI can be calculated using the following formula: PCI = N PSS +N SSS ×3. Where N PSS Represents the PSS sequence, N SSS This represents the SSS sequence.

[0142] Optionally, obtaining the measurement result information corresponding to each target PCI based on the PSS sequence includes:

[0143] (i) Obtain the PSS sequence position corresponding to each target PCI based on the PSS sequence corresponding to each target PCI;

[0144] (ii) Based on the position of each PSS sequence, obtain the first time domain position of the physical broadcast channel PBCH corresponding to each target PCI.

[0145] In this step, the position of PBCH (i.e., the first time-domain position) can be calculated based on the position of the PSS sequence. It should be noted that PBCH consists of three consecutive symbols, denoted as PBCH0, PBCH1, and PBCH2. Specifically, PBCH0 = P... SSS +L;PBCH1=P SSS +2L;PBCH2=P SSS +3L.

[0146] Where PBCH0 represents the start symbol position of PBCH, PBCH1 represents the second symbol position of PBCH, PBCH2 represents the third symbol position of PBCH, and P SSS The position of the SSS sequence is indicated, and L represents the length of the time-domain data per symbol.

[0147] (iii) Based on the first time domain position of each PBCH, obtain the measurement result information corresponding to each target PCI.

[0148] It should be noted that the process of obtaining the measurement result information corresponding to each target PCI based on the first time-domain position of each PBCH is divided into the following two cases:

[0149] Scenario 1 involves determining the measurement results of the beam corresponding to the sequence group in the cell corresponding to the target PCI based on the sequence group obtained in the above process:

[0150] Optionally, obtaining the measurement result information corresponding to each target PCI based on the first time-domain position of each PBCH includes:

[0151] (1) Obtain the PBCH data corresponding to each target PCI according to the first time domain position of each PBCH;

[0152] (2) Verify each PBCH data according to the Cyclic Redundancy Check (CRC) code in each PBCH data to obtain the verification result.

[0153] In this step, the PBCH CRC result can be parsed based on the acquired PBCH data, that is, each PBCH data is verified.

[0154] (3) Obtain the first RSRP of the SSS sequence in the sequence group corresponding to the first target PCI, and determine the first RSRP as the measurement result information corresponding to the first target PCI; the first target PCI is the target PCI corresponding to the PBCH data whose verification result is correct.

[0155] In other words, when verifying each PBCH data, if the parsing is correct (i.e., the verification result is correct), the first RSRP of the SSS sequence can be used as the measurement result of the target PCI corresponding to the SSS sequence; if the parsing is incorrect, the measurement result of the sequence group will not be recorded.

[0156] Furthermore, in this embodiment of the invention, a measurement list can be established to store measurement result information. Specifically, the frame header position corresponding to the sequence group can be calculated, and the frame header position, measurement result, and corresponding PCI of the sequence group can be recorded in the measurement list to facilitate cell handover.

[0157] Scenario 2: Determine the measurement results of other beams in the cell corresponding to the target PCI:

[0158] Optionally, obtaining the measurement result information corresponding to each target PCI based on the first time-domain position of each PBCH includes:

[0159] (1) Based on the received measurement configuration information and the frame header position information of the sequence group corresponding to each target PCI, obtain the second time domain position of the PBCH corresponding to at least one beam in the cell corresponding to each target PCI.

[0160] It should be noted that the measurement configuration information is sent by the base station.

[0161] (2) Obtain the PBCH data corresponding to each beam according to the second time domain position of each PBCH.

[0162] In this embodiment, by obtaining the second time-domain location, the PBCH data corresponding to other beams in the cell corresponding to the target PCI can be obtained, thereby measuring these beams.

[0163] (3) Verify each PBCH data according to the Cyclic Redundancy Check (CRC) code in each PBCH data to obtain the verification result.

[0164] In this step, by verifying the PBCH data, it can be determined whether the PBCH data is valid, thereby reducing unnecessary measurements and improving measurement efficiency. This is especially suitable for 5G communication systems with a large number of neighboring cells. Compared with the existing technology that measures all beams of all cells, this embodiment of the invention reduces the number of cells that need to be measured by filtering, thereby reducing the measurement time under 5G with a large number of neighboring cells. By integrating the measurement results of multiple beams under PCI based on the PBCH CRC result, the technical effect of measuring multiple cells under 5G with a large number of neighboring cells is achieved, which can effectively improve the measurement efficiency of 5G with a large number of neighboring cells.

[0165] (4) Based on the frame header position information of the sequence group corresponding to the first target PCI, obtain the temporal position of the SSS in each beam in the cell corresponding to the first target PCI; the first target PCI is the target PCI corresponding to the PBCH data whose verification result is correct;

[0166] (5) Based on the time domain position of the SSS, obtain the second RSRP of the SSS in each beam, and determine the second RSRP as the measurement result information corresponding to the first target PCI.

[0167] In this embodiment, when verifying each PBCH data, if the parsing is correct (i.e., the verification result is correct), the time domain position of the SSS can be calculated based on the frame header position, and the SSS can be used for measurement to obtain measurement result information. The measurement results of each beam are then maintained in the measurement list. If the parsing is incorrect, the measurement results of the sequence group are not recorded.

[0168] In this embodiment of the invention, unmeasured beams can be measured according to the neighboring cell measurement parameter settings (i.e., measurement configuration information); by establishing a measurement list, the measured PCIs can be maintained, as well as the measurement results of all beams with the same PCI can be integrated, which facilitates cell handover.

[0169] Optionally, the method further includes:

[0170] Store measurement list information;

[0171] The measurement list information includes the PCI information corresponding to the first target PCI, the frame header position information, and the measurement result information.

[0172] It should be noted that, in this embodiment of the invention, a measurement list can be established to store measurement result information.

[0173] like Figure 2 As shown, the application of the embodiments of the present invention in specific scenarios is explained below:

[0174] S201: Based on the received time-domain data (e.g., 20ms of time-domain data), search for the positions of the M most correlated PSS sequences;

[0175] S202: Calculate the SSS sequence position based on the PSS sequence position.

[0176] In this step, based on the position of the PSS sequence, the SSS sequences with the highest correlation can be traversed to obtain M sequence groups; the PCI corresponding to the sequence group and the position of the SSS sequence (i.e., the time domain position of the SSS sequence) can be calculated, and the RSRP value of the SSS sequence can be measured.

[0177] S203: Compare the RSRP values ​​of M sequence groups (i.e., the RSRP of the SSS sequence in the sequence group) and filter out N sequence groups that meet the conditions.

[0178] Specifically, in this step, based on the measurement results of the A3 measurement threshold and the main area synchronization signal block (SSB), sequence groups with values ​​higher than the preset threshold (which can be the measurement results of the main area SSB plus the A3 measurement threshold) are selected from the measurement results of M sequence groups, resulting in N sequence groups and the measurement results of each sequence group (i.e., the RSRP of the SSS sequence in the sequence group).

[0179] S204: Set the measurement list to empty.

[0180] In this embodiment of the invention, a measurement list can be established to store measurement result information. Specifically, it can store PCI information, frame header location information, and measurement result information to facilitate cell handover.

[0181] For example, a measurement list can be created before measurement, and the measurement list is empty at this time; then, N sequence groups are measured respectively, and the measurement results are recorded until all N sequence groups are measured. Then the measurement cycle is completed, and the cycle begins to the next measurement cycle.

[0182] S205: Determine whether all N sequence groups have been measured; if not, proceed to S206; if yes, proceed to S214.

[0183] Optionally, during measurement, each sequence group can be checked separately to confirm whether its corresponding PCI already exists in the measurement list; if it does, it means that it has been measured, and then it can be checked whether the next sequence group has been measured.

[0184] S206: Determine whether a certain sequence group (corresponding PCI) has completed the measurement; if yes, execute S205; if no, execute S207.

[0185] For example, determine whether the PCI corresponding to each sequence group is in the measurement list. If the PCI is in the measurement list, it means that the PCI has been measured.

[0186] S207: Based on the PSS sequence position of the sequence group, calculate the PBCH time-domain data position (i.e., the first time-domain position) corresponding to the sequence group, and parse the CRC result of the PBCH, i.e., verify the PBCH data;

[0187] S208: Determine if the verification result is correct; if the verification result is correct, proceed to S209; otherwise, proceed to S205.

[0188] S209: Calculate the frame header position;

[0189] S210: Determine whether the remaining beam measurement is complete based on the measurement configuration; if not, proceed to S211; if yes, proceed to S205.

[0190] S211: Calculate the position of the PBCH of the beam based on the frame header position, obtain the PBCH data, and parse the PBCH results, that is, verify each PBCH data.

[0191] S212: If PBCH CRC is OK, that is, the verification result is correct, then execute S213; otherwise, execute S210.

[0192] S213: Calculate the SSS sequence position and measure the RSRP value of the SSS sequence of the beam. Record the measurement results of the beam in the measurement list and execute S210.

[0193] S114: This measurement is complete. Proceed to the next measurement cycle.

[0194] In this embodiment, the corresponding PCI can be calculated by searching for PSS and SSS sequences. Neighbor cell measurements are then performed based on the searched PSS and SSS sequence locations to filter out PSS and SSS sequence locations that meet the threshold. Subsequently, the positions of other beams under the same PCI are calculated and measured to maintain the measurement results for all beams in the cell. This process reduces the range of measurements required through filtering, thus improving measurement efficiency.

[0195] The cell measurement method in this embodiment obtains the PSS sequence, SSS sequence and corresponding PCI through the received time domain data, and filters them according to the measurement threshold to obtain the PCI that meets the conditions for measurement. This can reduce the number of cells that need to be measured, thereby reducing the measurement time under a large number of neighboring cells in 5G, enabling the UE to quickly enter the handover state and improving the handover efficiency of the UE.
