Description

Technical Field

[0001] This application relates to, but is not limited to, the field of communications, and particularly to a cell measurement method, terminal equipment, computer-readable storage medium, and computer program product. Background Technology

[0002] For terminals supporting low-power wake-up signal radio (LP-WUR) (LR), due to cost constraints, the LR may support fewer operating frequency bands than the main radio (MR) module. This means that if the terminal camps on a frequency band supported only by MR, it cannot offload MR measurements to the LR, thus preventing energy saving through the LR. To maximize the utilization of LR capabilities, in scenarios where the LR supports fewer operating frequency bands than the MR, the 3rd Generation Partnership Project (3GPP) Radio Access Network (RAN) plenary meeting #106 proposed three solutions for MR and LR operating on different frequencies: Solution 1: MR is preferentially camped on the same frequency band as LR; Solution 2: MR is preferentially camped on the same frequency band as LR; Solution 3: MR is not preferentially camped on the same frequency band as LR, but can be redirected via dedicated signaling based on LR band load.

[0003] When using Solution 2, if the terminal camps on a cell within the LR-supported frequency band and the cell reselection measurement criteria in the relevant technology are applied, i.e., all the frequency points to be measured in the serving cell are measured according to the cell reselection measurement criteria, it will result in a waste of measurement resources and an increase in measurement latency. Summary of the Invention

[0004] This application provides a cell measurement method, terminal equipment, computer-readable storage medium, and computer program product, avoiding the problems of wasted measurement resources and prolonged measurement latency caused by related technologies.

[0005] In a first aspect, embodiments of this application provide a cell measurement method, applied to a terminal device, comprising:

[0006] A first measurement result is obtained by measuring the frequency points within the first frequency point set; wherein, the first frequency point set includes a first frequency point and a second frequency point, or the first frequency point, the second frequency point, and a third frequency point; the first frequency point is the frequency point corresponding to the serving cell of the terminal device; the second frequency point is the frequency point supported by the first receiver of the terminal among the frequency points to be tested; the third frequency point is the frequency point supported by the second receiver of the terminal among the frequency points to be tested, and has a higher priority than the frequency point priority of the serving cell.

[0007] Upon receiving the first signal, a cell reselection is performed based on the first measurement result; wherein the first signal is used to indicate paging monitoring.

[0008] Secondly, embodiments of this application provide a terminal device, the terminal device comprising:

[0009] The processing module is used to measure the frequency points within the first frequency point set to obtain a first measurement result; wherein, the first frequency point set includes a first frequency point and a second frequency point, or the first frequency point, the second frequency point, and a third frequency point; the first frequency point is the frequency point corresponding to the serving cell of the terminal device; the second frequency point is the frequency point supported by the first receiver of the terminal among the frequency points to be tested; the third frequency point is the frequency point supported by the second receiver of the terminal among the frequency points to be tested, and has a higher priority than the frequency point priority of the serving cell.

[0010] The processing module is further configured to, after receiving the first signal, reselect the cell where the terminal device is to be hosted based on the first measurement result and initiate random access; wherein the first signal is used to indicate paging monitoring.

[0011] Thirdly, embodiments of this application provide a terminal device, the terminal device comprising:

[0012] Memory, used to store executable instructions;

[0013] The processor, when executing executable instructions stored in the memory, implements the aforementioned cell measurement method.

[0014] Fourthly, embodiments of this application provide a computer-readable storage medium storing one or more programs that can be executed by one or more processors to implement the aforementioned cell measurement method.

[0015] Fifthly, embodiments of this application provide a computer program product, including a computer program that, when executed by a processor, implements the aforementioned cell measurement method.

[0016] After the terminal device camps on a cell within the frequency band supported by the first receiver, it does not measure all the frequency points to be tested, but only a portion of the frequency points to be tested (i.e., the frequency points concentrated in the first frequency point). This reduces the probability of measuring frequency points that do not have a reselection opportunity, saves measurement resources, and avoids additional power consumption.

[0033] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0035] Before explaining this application, the cell reselection measurement criteria in the related art are explained here:

[0036] The UE uses the following rules to limit the required measurements.

[0037] If the serving cell satisfies S rxlev >S IntraSearchP And S qual >S IntroSearchQ (If the serving cellfulfils S rxlev >S IntraSearchP and S qual >S IntroSearchQ ):

[0038] The UE may not perform intra-frequency measurements.

[0039] Otherwise, the UE shall perform intra-frequency measurements.

[0040] For an NR inter-frequency or inter-RAT frequency with a reselection priority higher than the reselection priority of the current NR frequency, the UE shall perform measurements of the higher priority NR inter-frequency or inter-RAT frequencies.

[0041] For NR inter-frequency with a reselection priority equal to or lower than the current NR frequency, and for inter-RAT frequency with a reselection priority lower than the current NR frequency:

[0042] If the serving cell satisfies S rxlev >S nonIntraSearchP And S qual >S nonIntraSearchQ (If the serving cell fulls S rxlev >S nonIntraSearchP and S qual >S nonIntraSearchQ ):

[0043] The UE may choose not to perform measurements of NR inter-frequency cells of equal or lower priority, or inter-RAT frequency cells of lower priority.

[0044] Otherwise, the UE shall perform measurements of NR inter-frequency cells of equal or lower priority, or inter-RAT frequency cells of lower priority.

[0045] It should be noted that, for MR and LR which are different and operate on different frequency points, when using Solution 2, the terminal is in a cell within the frequency band supported by LR when it is on the MR. At this time, the system message configures the serving cell frequency point as f1, and the other frequency points to be tested as f2, f3, f4, and f5.

[0046] Within the above frequency range, f1, f2 and f3 are the operating frequencies supported by both LR and MR, while f4 and f5 are the operating frequencies supported by MR.

[0047] When the terminal is camped on the serving cell, and measurements are taken according to the cell reselection measurement criteria in the relevant technology, such as S... rxlev nonIntraSearchP and S qual nonIntraSearchQ The terminal needs to measure both intra-frequency and inter-frequency points. The measurement delay is: max(serving cell measurement delay, intra-frequency measurement delay) + 4 * inter-frequency measurement delay, i.e., max(serving cell measurement delay, intra-frequency measurement delay) + 4 * inter-frequency measurement delay. The measurement results are then used for R-criterion ranking. If the R-criterion ranking is as follows: f4 > f2 > f3 > f1 > f5, but according to the UE's priority camping LR-supported frequency point criterion, the UE will reselect to frequency point f2. Based on the above process, it can be seen that even if frequency point f4 is measured, its measurement result will not be used for R-criterion evaluation. Clearly, the cell reselection measurement criterion in related technologies does not consider the LR priority camping mechanism, which will cause the terminal to measure frequencies without reselection opportunities when it prioritizes camping on the LR working frequency point, resulting in wasted measurement resources and additional power consumption.

[0048] The above, S rxlev The received RSRP value during cell selection; S qual The received RSRQ value during cell selection; S IntraSearchP The RSRP signal level threshold value characterizing the start of the same-frequency measurement; S IntroSearchQ Characterizes the threshold value of the RSRQ signal level for initiating synchronous frequency measurement; S nonIntraSearchP The RSRP signal level threshold value characterizing the initiation of inter-frequency measurement; S nonIntraSearchQ The threshold value of the RSRP signal level that characterizes the start of inter-frequency measurement.

[0049] Figure 2 A flowchart illustrating a cell measurement method provided in this application embodiment is shown below. Figure 2 As shown, this method is applied to Figure 1 ​​The terminal device 110 in the communication system 100 shown includes the following method:

[0050] Step 201: Measure the frequency points in the first frequency point set to obtain the first measurement result.

[0051] The first frequency point set includes the first frequency point and the second frequency point, or the first frequency point, the second frequency point and the third frequency point; the first frequency point is the frequency point corresponding to the serving cell of the terminal device; the second frequency point is the frequency point supported by the first receiver of the terminal among the frequency points to be tested; the third frequency point is the frequency point supported by the second receiver of the terminal among the frequency points to be tested, and has a higher priority than the frequency point of the serving cell.

[0052] In this embodiment of the application, the first frequency point is the frequency point corresponding to the serving cell and / or the camp on cell of the terminal device.

[0053] In this embodiment of the application, the first receiver may be an LR, that is, the second frequency point is the frequency point supported by the LR among the frequency points to be tested.

[0054] In this embodiment of the application, the first receiver may be the receiver corresponding to the MR, that is, the third frequency point is a frequency point that is only supported by the MR among the frequency points to be tested, and has a higher priority than the frequency point priority of the serving cell, that is, a high priority frequency point that is only supported by the MR relative to the priority of the serving cell.

[0055] For example, when a terminal initially accesses the network, it accesses and camps on frequency point f1; the frequency points to be tested are f2, f3, f4, and f5; LR supports frequency points including f1 and f2; the priority of f1 is 3, the priority of f2 is 3, the priority of f3 is 3, the priority of f4 is 3, and the priority of f5 is 7; then, the first frequency point is frequency point f1; the second frequency point is frequency point f2; and the third frequency point is frequency point f5.

[0056] In this embodiment of the application, in order to ensure that the terminal device can always access the cell with good signal quality, the terminal device needs to measure the frequency point where the serving cell is located and the frequency points around the cell (i.e., the frequency points in the first frequency point set of this application), and switch to the cell with the best quality according to the measurement results.

[0057] In this embodiment, there can be one or more frequency points to be tested. This embodiment does not limit the number of frequency points to be tested; in common cases, there are multiple. The frequency point to be tested can be the serving cell frequency itself, one or more co-frequency points, one or more different frequency points, or one or more different system frequency points near the serving cell frequency. A co-frequency point is a frequency point with the same frequency and radio access technology as the serving cell frequency point. A different frequency point is a frequency point with a different frequency but the same radio access technology as the serving cell frequency point. A different system frequency point is a frequency point with both a different frequency and radio access technology than the serving cell frequency point, or it can be a frequency point with the same frequency but a different radio access technology than the serving cell frequency point. The network can configure all the frequency points to be tested around the serving cell, or it can configure only a portion of the frequency points.

[0058] In this embodiment of the application, frequency point can also be understood as frequency.

[0059] In some embodiments, before a first moment, the terminal device measures the frequency points within a first frequency point set according to measurement criteria; wherein, at the first moment, the terminal device receives the moment corresponding to the paging monitoring.

[0060] Here, if the terminal needs to perform neighbor cell measurement according to the measurement criteria, then the terminal performs cell reselection measurement on the frequency points within the first frequency point set; if the terminal only needs to perform co-frequency neighbor cell measurement according to the measurement criteria, then the terminal performs cell reselection measurement on the co-frequency neighbor cells within the first frequency point set; if the terminal only needs to perform serving cell measurement according to the measurement criteria, then the terminal does not perform neighbor cell reselection measurement.

[0061] Step 202: After receiving the first signal, perform cell reselection based on the first measurement result.

[0062] The first signal is used to indicate paging monitoring.

[0063] In this embodiment of the application, the first information can be a paging signal, that is, after the terminal device receives the paging signal, it triggers cell reselection or handover.

[0064] It should be noted that paging is the process by which network-side devices periodically send paging messages to terminals in an idle or inactive state in order to wake up the terminals in the idle or inactive state and bring them back to the connected state.

[0065] This application provides a cell measurement method, which includes: a terminal device measuring frequency points within a first frequency point set to obtain a first measurement result; wherein the first frequency point set includes a first frequency point and a second frequency point, or a first frequency point, a second frequency point, and a third frequency point; the first frequency point is the frequency point corresponding to the serving cell of the terminal device; the second frequency point is a frequency point supported by a first receiver of the terminal among the frequency points to be measured; the third frequency point is a frequency point supported by a second receiver of the terminal among the frequency points to be measured, and has a higher priority than the frequency point priority of the serving cell; after receiving a first signal, the terminal device performs cell reselection based on the first measurement result; wherein the first signal is used to indicate paging monitoring. That is, after the terminal device camps on a cell within the frequency band supported by the first receiver, it does not measure all the frequency points to be measured, but only a portion of the frequency points to be measured (i.e., the frequency points in the first frequency point set). This reduces the probability of measuring frequency points without reselection opportunities, saves measurement resources, and avoids additional power consumption.

[0066] In some embodiments, the cell reselection action based on the first measurement result in step 202 is implemented through step A1, or through steps A2 to A3, or through steps A4 to A5:

[0067] Step A1: If the first frequency point set includes the third frequency point, and the cell quality of the first cell corresponding to one of the third frequency points is greater than (exceeds) the quality threshold within a preset time period, after receiving the paging message, the terminal device's camping cell is reselected to the first cell, and random access is initiated in the first cell.

[0068] Step A2: If the first frequency point set includes the third frequency point, and the cell quality of the cell corresponding to the third frequency point is equal to or less than (does not exceed) the quality threshold within a preset time period, measure the frequency points in the second frequency point set to obtain the second measurement result.

[0069] In this embodiment of the application, if the first frequency point set includes a third frequency point, and the cell quality of the cell corresponding to the third frequency point is equal to or less than (does not exceed) the quality threshold within a preset time period, the frequency points in the second frequency point set are measured at the first moment or after receiving the paging message.

[0070] The second frequency point set includes the fourth frequency point; the fourth frequency point is the other frequency points in the frequency points to be tested besides the second and third frequency points.

[0071] Step A3: After receiving the paging message, based on the second measurement result, reselect the cell where the terminal device will be camped and initiate random access.

[0072] In some embodiments, after receiving a paging message, the fourth frequency point is sorted according to a sorting rule, such as the R criterion. If the sorting of the second cell corresponding to one of the fourth frequency points is higher than the sorting of the serving cell, the terminal device's camp cell is reselected to the second cell, and random access is initiated in the second cell; wherein, the second cell is a neighboring cell of the serving cell. If the sorting of all the fourth frequency points is lower than the sorting of the serving cell, random access is initiated in the serving cell.

[0073] Step A4: If the first frequency point set does not include the third frequency point, measure the frequency points in the third frequency point set to obtain the third measurement result.

[0074] The third frequency point set includes the fifth frequency point; the fifth frequency point is the other frequency points in the frequency points to be measured, excluding the second frequency point.

[0075] Step A5: After receiving the paging message, based on the third measurement result, reselect the cell where the terminal device will camp and initiate random access.

[0076] In some embodiments, after receiving a paging message, the terminal device determines whether there is at least one frequency point with a higher priority than the serving cell frequency point.

[0077] Here, if there is at least one frequency point with a higher priority than the serving cell frequency point, the at least one frequency point is measured; if the cell quality of the third cell corresponding to one of the at least one frequency point is greater than the quality threshold within a preset time period, the terminal device's camping cell is reselected to the third cell, and random access is initiated in the third cell.

[0078] Here, if there is no frequency point with a priority higher than that of the serving cell, the fifth frequency point is sorted according to the sorting rules; if the fourth cell corresponding to one of the fifth frequency points has a higher sorting than that of the serving cell, the terminal device's camp cell is reselected to the fourth cell, and random access is initiated in the fourth cell; wherein, the fourth cell is a neighboring cell of the serving cell; if the sorting of the fifth frequency point is lower than that of the serving cell, random access is initiated in the serving cell.

[0079] As can be seen, this application specifies the terminal's measurement and cell reselection behaviors before receiving WUS, during the period from receiving WUS to receiving the Paging message, and after receiving the Paging message. This ensures that the terminal only measures frequencies with a possibility of reselection, preventing wasted measurement resources. Furthermore, this application also establishes a measurement scheme for high-priority frequencies. By measuring high-priority frequencies in advance and prioritizing measurement, it reduces latency for cell reselection and subsequent Random Access Channel (RACH), ensuring network performance. Specifically:

[0080] Step 1: Before the first moment (i.e., when the terminal receives the LP-WUS instruction to Paging for listening), when the terminal performs cell reselection measurement, it performs cell reselection measurement only on the frequency points within the first frequency point set according to the measurement criteria.

[0081] The first frequency point set includes the frequency points supported by LR among the frequency points of the serving cell and the frequency points to be measured in the network configuration. In addition, it may also include high-priority frequency points that are supported only by MR and have a higher priority relative to the serving cell priority.

[0082] Step 2: After the first moment, the terminal performs the following actions based on the measurement results of the first frequency point set:

[0083] If the first frequency set includes high-priority frequencies relative to the serving cell priority, and the cell quality of a cell measured at a high-priority cell frequency exceeds a threshold for a period of time, then after the second time (when the terminal receives the Paging message), the terminal will reselect to camp on a high-priority frequency cell and initiate RACH.

[0084] If the first frequency set includes high-priority frequency points relative to the serving cell priority, but the cell quality measured at the high-priority cell frequency does not exceed the threshold within a certain period of time, then after the first or second time, the terminal performs cell reselection measurement on the frequency points of the second frequency set, and after the second time, selects a suitable cell to camp on and initiates RACH.

[0085] The second frequency set includes other frequency points in the network configuration that are not part of the first frequency set and are not part of the high-priority frequency points.

[0086] Here, the terminal selects a suitable cell to camp on and initiates RACH by: sorting all the frequency points to be measured in the network configuration according to the sorting criterion R; if there is a neighboring cell whose R criterion ranking is higher than that of the serving cell, the terminal performs cell reselection to camp on the target neighboring cell and initiates RACH; otherwise, the terminal initiates RACH in the serving cell.

[0087] If the first frequency set does not include high-priority frequencies relative to the serving cell priority, then after the first or second time point, the terminal performs cell reselection measurement on the frequencies of the third frequency set, and after the second time point, selects a suitable cell to camp on and initiates RACH.

[0088] The third frequency set includes other frequency points in the network configuration that are not part of the first frequency set.

[0089] Here, the terminal performs cell reselection measurements on the frequencies of the third frequency set: if the frequencies of the third frequency set include high-priority frequencies relative to the serving cell priority, the terminal prioritizes measuring the high-priority frequencies; otherwise, the terminal performs cell reselection measurements on the frequencies of the third frequency set.

[0090] Here, the terminal selects a suitable cell to camp on and initiates RACH, including: if the high-priority frequency cell reselection criterion is met, the terminal reselects to a high-priority frequency cell and initiates RACH. Otherwise, for all the frequency points to be measured in the network configuration, they are sorted according to the sorting criterion R. If there is a neighboring cell with a higher R criterion ranking than the serving cell, the terminal reselects to that target neighboring cell and initiates RACH; otherwise, the terminal initiates RACH in the serving cell.

[0091] It should be noted that in Treselection RAT Within a certain time period, if the quality of the community exceeds the threshold S... rxlev Thresh x,highP or S qual Thresh x,highQ This satisfies the high-priority frequency cell reselection criterion.

[0092] Among them, Treselection RAT The timer duration representing cell reselection within the same priority range; S rxlev The received RSRP value during cell selection; S qual The received RSRQ value during cell selection; Thresh x,highP Threshold is the reselection decision threshold that characterizes the RSRP signal that indicates cell reselection to a higher priority level. x,highQ The reselection decision threshold characterizes the RSRQ signal that represents the cell reselection to a higher priority.

[0093] The following will describe exemplary applications of the embodiments of this application in real-world application scenarios.

[0094] In some embodiments, when a terminal initially accesses the network, it accesses and camps on the f1 frequency point according to the principle of prioritizing camping on the LR-supported frequency points;

[0095] The terminal reports LR capability, and LR supports carrier frequency points f1 and f2 working frequency points;

[0096] The network transmits a frequency band list in system information block (SIB) 2 / SIB4 signaling, with frequencies f2, f3, f4, and f5 to be tested;

[0097] Network SIB2 is configured with the service cell carrier frequency point f1 priority set to 3;

[0098] The network SIB4 is configured with the following inter-frequency priorities: f2 priority is 3, f3 priority is 3, f4 priority is 3, and f5 priority is 7.

[0099] like Figure 3 As shown, before the terminal receives the Paging message, for example, before the time corresponding to the UE receiving the LP-WUS paging indication (UE receives LP-WUS with paging indication), i.e., before T1, the terminal only measures the serving cell carrier frequency f1 and the LP-WUS supported carrier frequency f2.

[0100] After the terminal receives the Paging message (T2), the terminal prioritizes measuring the higher carrier frequency (f5).

[0101] It should be noted that the cell corresponding to frequency point f5 is cell 1. If in Treselection... RAT Within a given time period, the quality of cell 1 exceeds the threshold, i.e., S. rxlev Thresh x,highP Then, the terminal reselects cell 1 on frequency f5 and initiates RACH on frequency f5 (UE send RACH on higher carrier frequency f5).

[0102] If in Treselection RAT Within the specified time, the quality of the corresponding community in community 1 did not exceed the threshold S. rxlev ≤Thresh x,highPThen, the terminal measures the second set of frequency points, such as frequency points f3 and f4, and performs cell reselection to the target cell according to the sorting criterion R, and initiates RACH. If R3>R4>R1>R5>R2 is determined according to the R criterion, then the UE sends RACH at point f3.

[0103] In some embodiments, the terminal reports LR capability, and LR supports operating frequencies f1 and f2.

[0104] The network releases the terminal to idle state through the RRC Release message, and instructs the terminal to camp on the f1 frequency cell through redirectedCarrierInfo. It also sends cellReselectionPriorities to indicate the cell reselection frequency priority as follows: f1 priority is 3, f2 priority is 3, f3 priority is 3, f4 priority is 3, and f5 priority is 7.

[0105] like Figure 4 As shown, before the terminal receives the Paging message, such as before the time T1 corresponding to the UE receiving the LP-WUS paging indication, the terminal measures the serving cell frequency f1, the LP-WUS supported carrier frequency f2, and the higher carrier frequency f5.

[0106] It should be noted that the cell corresponding to frequency point f5 is cell 1. After the terminal receives the Paging message (T2), if it is in Treselection... RAT Within a given time period, the quality of community 1 exceeds the threshold, i.e., S. rxlev Thresh x,highP If the UE reselects to camp on cell 1 corresponding to the higher priority f5 frequency point, it will initiate RACH on the f5 frequency point.

[0107] If in Treselection RAT Within the specified time, the quality of the corresponding community in community 1 did not exceed the threshold S. rxlev ≤Thresh x,highP Therefore, before T3, the terminal performs cell reselection measurements on the f3 and f4 frequencies in the second frequency point set, selects a suitable cell to camp on, and initiates RACH.

[0108] In some embodiments, the terminal reports LR capability, and LR supports operating frequencies f1 and f2.

[0109] The network releases the terminal to idle state through the RRC Release message, and instructs the terminal to camp on the f1 frequency cell through redirectedCarrierInfo. It also sends cellReselectionPriorities to indicate the cell frequency reselection priority as follows: f1 priority is 3, f2 priority is 3, f3 priority is 3, f4 priority is 3, and f5 priority is 7.

[0110] like Figure 5 As shown, before the terminal receives the LP-WUS instruction to Paging (T1), the terminal measures the first frequency point, the serving cell carrier frequency f1, the LP-WUS supported carrier frequency f2, and the higher priority frequency f5.

[0111] It should be noted that the cell corresponding to the f5 frequency point is cell 1. After the terminal receives the LP-WUS indication for paging monitoring, if in Treselection... RAT Within the specified time, the quality of community 1 did not exceed the threshold, i.e., S. rxlev ≤Thresh x,highP Then, the terminal measures the f3 and f4 frequencies in the second frequency set. After receiving the Paging message, it selects a suitable cell to camp on and initiates RACH. If R3>R4>R1>R5>R2 is determined according to the R criterion, the UE sends RACH on the f3 frequency.
