[0035] It should be understood that all or part of the functions of the communication device in the present application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform, such as a cloud platform.

[0036] The present application improves the acquisition of cell-level measurement results, R criterion, etc. First, these technologies are described.

[0037] Acquiring cell-level measurement results based on beam measurement results

[0038] For some cells (such as high-frequency cells), in order to offset the greater characteristics of spatial attenuation of high-frequency signals to some extent, beam sweeping is usually used to achieve greater cell signal coverage. In other words, through the measurement process, the terminal device can obtain the measurement results corresponding to multiple beams of the same cell. Assuming that the terminal device measures m beam measurement results corresponding to m beams in cell A, where m is a positive integer, the relevant standard stipulates that the terminal device obtains the cell-level measurement result corresponding to cell A through the following process: selecting K beams from the m beams whose beam measurement results are greater than a certain threshold (which can be the first threshold described below), K is a positive integer, and the value of K is less than or equal to n1, wherein the threshold and the parameter n1 are configured by the network device to the terminal device, and n1 is a positive integer; Then, the linear average result of the selected K beams is taken as the cell-level measurement result of cell A.

[0039] R criterion

[0040] The R criterion is a same-frequency cell or same-priority inter-frequency cell reselection criterion.

[0041] In related technologies, the R criterion is expressed as follows: R s = Q meas,s + Q hyst - Qoffset temp R n = Q meas,n - Qoffset - Qoffset temp .

[0042] The meanings of the parameters in the formula are shown in Table 1.

[0043] Table 1: Meanings of R criterion parameters

[0044] For ease of understanding, the following takes the NR system as an example to explain how the terminal device performs cell reselection based on the R value.

[0045] The NR system can support multi-beam operation. In multi-beam operation, when reselecting a cell, the gNB can configure the rangeToBestCell parameter through system information to determine the optimal cell.

[0046] If the gNB does not configure the rangeToBestCell parameter, the terminal device will reselect to the cell with the highest R value; otherwise (if the gNB configures the rangeToBestCell parameter), the terminal device will reselect to the cell with the largest number of beams whose R values belong to the range [R best -rangeToBestCell, R best ] and whose beam measurement results are higher than a threshold (for example, the threshold indicated by the absThreshSS-Consolidation parameter). Wherein, R best is the R value of the cell with the highest R value among the cells evaluated by the R criterion. If multiple cells satisfy the above conditions, the terminal will reselect to the cell with the highest R value among them.

[0047] It should be noted that the following constraints need to be met in the R value sorting and R value-based selection process: the new cell quality needs to be better than the current cell in the sorting for a duration longer than the value indicated by the TreselectionNR parameter; if the terminal device is in a non-ordinary mobile state, the TreselectionNR and Q hyst parameters need to be scaled; and the terminal device stays in the original cell for more than 1 second.

[0048] FIG. 2 is a schematic flowchart of a wireless communication method according to an embodiment of the present application. The method shown in FIG. 2 can be performed by a terminal device.

[0049] The method shown in FIG. 2 can include step S210.

[0050] In step S210, the terminal device determines a cell-level measurement result corresponding to a first cell based on beam measurement results corresponding to beams included in a first beam set and / or beam measurement results corresponding to beams included in a second beam set.

[0051] The beam measurement results corresponding to the beams included in the first beam set are beam measurement results corresponding to m beams associated with the first cell at a first time point obtained by the terminal device according to an actual measurement process. Wherein, m is a positive integer.

[0052] The actual measurement process is described below. Taking the first beam as an example, the actual measurement process for the first beam can be a process in which the terminal device actually measures a reference signal transmitted by the network device on the first beam. The beam measurement result obtained by the actual measurement process can be referred to as a measured beam measurement result or a measured beam quality. The beam measurement results corresponding to the m beams can all be referred to as measured beam measurement results.

[0053] The second beam set includes beam measurement results corresponding to n beams associated with the first cell at the first time, obtained by the terminal device according to a measurement prediction process. n is a positive integer.

[0054] The measurement prediction process is described below. Taking the second beam as an example, the measurement prediction process for the second beam can be that the terminal device obtains the beam measurement result corresponding to the second beam by means other than actual measurement (for example, by an AI model to predict the beam measurement result corresponding to the second beam set according to the actually measured beam measurement result corresponding to the first beam set). Wherein, the terminal device can not actually measure the reference signal transmitted by the network device on the second beam, or the network device does not transmit the reference signal on the second beam, or the terminal device does not receive the reference signal transmitted by the network device on the second beam. The beam measurement result obtained by the measurement prediction process can be referred to as a predicted beam measurement result or a predicted beam quality. The beam measurement results corresponding to n beams can all be referred to as predicted beam measurement results.

[0055] The first time can be any one of the times when the terminal device performs the measurement process. That is, the cell-level measurement result at any time when the terminal device performs the measurement process can be obtained based on the technical solutions provided in the present application.

[0056] The first cell can be a serving cell of the terminal device or a neighbor cell of the terminal device. That is, the method for determining the cell-level measurement result provided in the embodiments of the present application can be applied to the serving cell of the terminal device, and / or the method for determining the cell-level measurement result provided in the embodiments of the present application can be applied to the neighbor cell of the terminal device.

[0057] In the present application, the first cell is a measurable cell and the first cell allows the terminal device to perform a measurement prediction behavior. Wherein, the measurable cell means that the terminal device can measure the reference signal transmitted by the corresponding cell and the cell does not belong to the prohibited measurement cell range. The measurable cell can include the serving cell and / or the neighbor cell. If the first cell allows the terminal device to perform the measurement prediction behavior, the beam measurement results corresponding to a part of beams (for example, the beams included in the first beam set described above) associated with the first cell are obtained by the terminal device through an actual measurement process, and the beam measurement results corresponding to another part of beams (for example, the beams included in the second beam set described above) associated with the cell are obtained by the terminal device through a measurement prediction process.

[0058] With the development of communication technology (for example, the gradual application of AI technology in communication systems), some communication processes can be implemented through a prediction function (for example, an AI-based prediction function). After introducing the prediction function in the measurement process, the present application proposes a method for determining a cell-level measurement result. On the one hand, the method proposed in the present application makes the determination scheme of the cell-level measurement result more suitable for the development of communication technology; on the other hand, the method proposed in the present application enables the terminal device to predict the measurement results of a part of beams, thereby saving part of the measurement overhead.

[0059] It should be noted that the method provided by the present application can be applied to scenario one, scenario two or other scenarios. In scenario one, the terminal device is in a connected state, and the terminal device performs a mobility measurement task (for example: assisting the network device to make a handover decision) under the configuration of the network device. The measurement object includes a serving cell and / or a neighbor cell, that is, the measurement object of the terminal device includes one or more first cells, which can be a serving cell or a neighbor cell. In scenario two, the terminal device is in an idle state or an inactive state, and the terminal device performs a mobility measurement task (for example: the terminal device performs a cell selection or cell reselection measurement task) under the configuration of the network device. The measurement object includes a serving cell and / or a neighbor cell, that is, the measurement object of the terminal device includes one or more first cells, which can be a serving cell or a neighbor cell.

[0060] It should be noted that in the present application, the measurement quantity corresponding to the beam measurement result can be RSRP, reference signal received quality (RSRQ) or signal to interference plus noise ratio (SINR). Correspondingly, the measurement quantity corresponding to the cell-level measurement result can be RSRP, RSRQ or SINR, respectively.

[0061] In some embodiments, the cell-level measurement result corresponding to the first cell at the first time can be determined based on the beam measurement results corresponding to at most p beams. Any one of the beam measurement results corresponding to at most p beams can belong to the beam measurement results corresponding to m beams or belong to the beam measurement results corresponding to n beams, and the beam measurement results corresponding to at most p beams are all greater than a first threshold value, and p is a positive integer.

[0062] It should be noted that the number of beams actually contained in the at most p beams can be less than or equal to p. The value of the parameter p can be configured by the network device or predefined.

[0063] The terminal device obtains the value of the first threshold value in any of the following manners: a protocol default manner, receiving a system broadcast message sent by the network device, or receiving special signaling sent by the network device. Exemplarily, the first threshold value can be a threshold value indicated by an absThreshSS-Consolidation parameter sent by the network device.

[0064] In this technical solution, the cell-level measurement result is determined based on the beam measurement result greater than the first threshold value. Based on this technical solution, the beam measurement result with a poor beam measurement result (less than or equal to the first threshold value) can be avoided to participate in the determination of the cell-level measurement result, so that the cell-level measurement result can be determined based on the beam measurement result with a good beam measurement result.

[0065] In some embodiments, if there is at least one beam measurement result greater than the first threshold value in the beam measurement results corresponding to the m beams, the cell-level measurement result corresponding to the first cell at the first time can be determined based on the beam measurement results corresponding to at most p beams. That is, whether to determine the cell-level measurement result corresponding to the first cell at the first time based on the beam measurement results corresponding to at most p beams can be determined according to whether there is at least one beam measurement result greater than the first threshold value in the measured beam measurement results, and the size of the beam measurement results corresponding to the n beams (i.e., the predicted beam measurement results) can not be considered.

[0066] Beam selection scheme one:

[0067] In some embodiments, if there is at least one beam measurement result greater than the first threshold value in the beam measurement results corresponding to the m beams, the beam measurement results corresponding to at most p beams can preferentially select the beam measurement results corresponding to the beams with beam measurement results greater than the first threshold value from the beam measurement results corresponding to the m beams. This scheme can be referred to as a preferential selection scheme.

[0068] For example, when the number of beam measurement results required in the cell-level measurement result calculation process is less than or equal to the number of good beams (beam measurement results greater than the first threshold value) in the measured beam measurement results associated with the cell, the beam measurement results used to determine the cell-level measurement result are all beam measurement results corresponding to the good beams in the measured beam measurement results associated with the cell.

[0069] For another example, when the number of beam measurement results required in the cell-level measurement result calculation process is greater than the number of good beams (beam measurement results greater than the first threshold value) in the measured beam measurement results associated with the cell, the terminal device can preferentially select the beam measurement results corresponding to all the good beams in the measured beam measurement results associated with the cell, and select the beam measurement results corresponding to the good beams from the predicted beam measurement results associated with the cell as a supplement to calculate the cell-level measurement result.

[0070] Compared with the measured beam measurement result, the predicted beam measurement result additionally contains a prediction error. The prediction error may include, for example, a prediction error of the AI model. Therefore, the predicted beam measurement result is less accurate than the measured beam measurement result. The present application proposes that the terminal device preferentially selects a beam measurement result corresponding to a good beam obtained through an actual measurement process (the beam measurement result corresponding to the good beam is greater than the first threshold value) to calculate the cell-level measurement result. This approach can reduce the degree of decline in the accuracy of the cell-level measurement result obtained after introducing the prediction function, because the beam measurement result corresponding to the good beam obtained through the measurement prediction process is not preferentially used to calculate the cell-level measurement result. That is, the measurement prediction error introduced by the prediction function is transmitted as little as possible into the cell-level measurement result.

[0071] The following illustrates how to achieve the preferential selection.

[0072] For example, if the number of beams whose beam measurement results are greater than the first threshold value in the m beam measurement results is greater than or equal to p, or if the number of beams whose beam measurement results are greater than the first threshold value in the m beam measurement results is less than p and the number of beams whose beam measurement results are greater than the first threshold value in the n beam measurement results is 0, the cell-level measurement result corresponding to the first cell at the first time is determined based on the beam measurement results corresponding to the maximum p beams in the m beam measurement results, wherein the beam measurement results corresponding to the maximum p beams in the m beam measurement results are all greater than the first threshold value.

[0073] For another example, if the number of beams whose beam measurement results are greater than the first threshold value in the m beam measurement results is less than p and there is at least one beam whose beam measurement result is greater than the first threshold value in the n beam measurement results, the cell-level measurement result corresponding to the first cell at the first time is determined based on z1 beam measurement results in the m beam measurement results and y1 beam measurement results in the n beam measurement results, wherein the z1 beam measurement results are all greater than the first threshold value, the number of beams whose beam measurement results are greater than the first threshold value in the m beam measurement results is z1, the y1 beam measurement results are all greater than the first threshold value, and (z1+y1) is not greater than p, z1, y1, m, n, and p are all positive integers.

[0074] In some embodiments, if there is at least one beam measurement result greater than the first threshold value among the m beam measurement results and the beam measurement result of the beam with the highest beam measurement result among the n beam measurement results is less than or equal to the first threshold value, the cell-level measurement result of the first cell at the first time is determined based on the beam measurement results of the at most p beams, wherein the beam measurement results of the at most p beams are all greater than the first threshold value, and any one of the beam measurement results of the at most p beams belongs to the m beam measurement results, and m, n and p are positive integers.

[0075] In some embodiments, if the beam measurement result of the beam with the highest beam measurement result among the m beam measurement results is less than or equal to the first threshold value and there is at least one beam measurement result greater than the first threshold value among the n beam measurement results, the cell-level measurement result of the first cell at the first time is determined based on the beam measurement results of the at most p beams, wherein the beam measurement results of the at most p beams are all greater than the first threshold value, and any one of the beam measurement results of the at most p beams belongs to the n beam measurement results, and m, n and p are positive integers. Based on this scheme, if the actual beam measurement results are all poor (less than or equal to the first threshold value), the at most p beams corresponding to the beam measurement results can still be determined according to the predicted beam measurement results, so as to obtain the cell-level measurement result.

[0076] It can be understood that in the above implementation manners, the terminal device distinguishes between the actual beam measurement results and the predicted beam measurement results to calculate the cell-level measurement result. Such a scheme balances the different situations (for example, error source differences) of the actual beam measurement results and the predicted beam measurement results, so that the calculation of the cell-level measurement result is more accurate.

[0077] Beam selection scheme two:

[0078] In some embodiments, if there is at least one beam measurement result corresponding to a beam among the m beam measurement results and the n beam measurement results that is greater than the first threshold value, the cell-level measurement result corresponding to the first cell at the first time is determined based on at most p beam measurement results corresponding to beams, the at most p beam measurement results corresponding to beams belonging to a third beam set containing a subset of beam measurement results. The third beam set contains beam measurement results corresponding to beams that are the m beam measurement results and the n beam measurement results corresponding to beams whose beam measurement results are greater than the first threshold value, and p is a positive integer. It can be understood that in this scheme, the terminal device does not distinguish between actual beam measurement results and predicted beam measurement results, and only considers the numerical value of the beam measurement results to calculate the cell-level measurement result. Such a scheme (also including other technical solutions that do not distinguish between actual beam measurement results and predicted beam measurement results in the following) can maximize the reuse of the manner of obtaining the cell-level measurement result in related technologies, and is relatively simple to implement.

[0079] In an implementation manner, the terminal device can select the first k beam measurement results corresponding to beams with the best beam measurement results among the beam measurement results corresponding to beams in the third beam set to calculate the cell-level measurement result, where k is a positive integer less than or equal to p. At this time, the cell-level measurement result corresponding to the first cell at the first time can be determined based on the aforementioned selected k beam measurement results corresponding to beams. It can be understood that in this implementation manner, the selected k beam measurement results corresponding to beams are the aforementioned at most p beam measurement results corresponding to beams.

[0080] The following describes how to determine the cell-level measurement result corresponding to the first cell at the first time based on the at most p beam measurement results corresponding to beams.

[0081] In some embodiments, the cell-level measurement result corresponding to the first cell at the first time can be determined based on a linear average of the at most p beam measurement results corresponding to beams. It can be understood that in the calculation of the cell-level measurement result, if the linear average is used for calculation, the actual beam measurement results and the predicted beam measurement results are not distinguished in the calculation process, and only the numerical value of each beam measurement result is considered, so that this calculation manner is relatively simple.

[0082] For example, in the case that the beam measurement results corresponding to the maximum p beams are selected preferentially from the beam measurement results corresponding to the m beams, the cell-level measurement result can be determined based on a linear average of the beam measurement results corresponding to the maximum p beams. In this scheme, when the beam measurement results corresponding to the maximum p beams are selected, the actually measured beam measurement results have been preferentially considered, and even if the cell-level measurement result is determined by means of linear average, the degree of decrease in the accuracy of the cell-level measurement result obtained after the introduction of the prediction function can be alleviated.

[0083] In some embodiments, the cell-level measurement result corresponding to the first cell at the first time can be determined based on a weighted average of the beam measurement results corresponding to the maximum p beams. That is, each of the beam measurement results corresponding to the maximum p beams is multiplied by a weighting factor before average calculation.

[0084] For example, if there is at least one beam measurement result corresponding to the m beams that is greater than the first threshold value and there is at least one beam measurement result corresponding to the n beams that is greater than the first threshold value, in the case that any one of the beam measurement results corresponding to the maximum p beams belongs to the beam measurement results corresponding to the m beams or the beam measurement results corresponding to the n beams, the cell-level measurement result corresponding to the first cell at the first time can be determined based on a weighted average of the beam measurement results corresponding to the maximum p beams.

[0085] By calculating the cell-level measurement result by means of weighted average, the corresponding weighting factor can be set separately according to different situations of the predicted beam result and the actually measured beam measurement result, so as to control the proportion of the corresponding beam measurement result in the cell-level measurement result, and thus the degree of decrease in the accuracy of the cell-level measurement result obtained after the introduction of the prediction function can be alleviated.

[0086] For example, in the case that the beam measurement results corresponding to the maximum p beams belong to the subset of the beam measurement results corresponding to the third beam set containing beams, the cell-level measurement result can be determined based on a weighted average of the beam measurement results corresponding to the maximum p beams. In this scheme, when the beam measurement results corresponding to the maximum p beams are selected, the actually measured beam measurement results and the predicted beam measurement results are not distinguished, and by means of weighted average, the degree of decrease in the accuracy of the cell-level measurement result obtained after the introduction of the prediction function can be alleviated.

[0087] For example, in the case that the beam measurement results corresponding to the maximum p beams are selected preferentially from the beam measurement results corresponding to the m beams, the cell-level measurement result can be determined based on the weighted average of the beam measurement results corresponding to the maximum p beams. In this scheme, when the beam measurement results corresponding to the maximum p beams are selected, the actually measured beam measurement results have been preferentially considered, so that the degree of decline in the accuracy of the cell-level measurement result obtained after the introduction of the prediction function can be reduced to some extent, and the cell-level measurement result determined by the weighted average can further reduce the degree of decline in the accuracy of the cell-level measurement result obtained after the introduction of the prediction function in a more flexible manner.

[0088] The present application proposes an implementation scheme of the weighted average for the following three branches.

[0089] Branch one

[0090] In branch one, the beam measurement results corresponding to the maximum p beams belong to the subset of the beam measurement results corresponding to the m beams, and the weighted factor associated with each of the beam measurement results corresponding to the maximum p beams can be equal to the reciprocal of the number of beams contained in the maximum p beams. Determining the cell-level measurement result corresponding to the first cell at the first time based on the weighted average of the beam measurement results corresponding to the maximum p beams is equivalent to determining the cell-level measurement result corresponding to the first cell at the first time based on the linear average of the beam measurement results corresponding to the maximum p beams, and m and p are both positive integers.

[0091] In the following branch of branch one, it is assumed that the beam measurement results corresponding to the maximum p beams contain the beam measurement results of z2 beams, where z2 is a positive integer less than or equal to p, and the weighted factor associated with each of the beam measurement results corresponding to the z2 beams is equal to 1 / z2. At this time, the cell-level measurement result corresponding to the first cell at the first time is determined based on the following public formula: (the sum of the z2 beam measurement results) divided by z2.

[0092] In an implementation manner, the beam measurement results corresponding to the maximum p beams belong to the subset of the beam measurement results corresponding to the m beams can be because the beam measurement results corresponding to the best k beams (k is a positive integer less than or equal to p) in the beam measurement results corresponding to the third beam set are all contained in the beam measurement results corresponding to the m beams, and the beam measurement results corresponding to the third beam set are the beam measurement results corresponding to the m beams and the beam measurement results corresponding to the n beams whose beam measurement results are greater than the first threshold value.

[0093] In another implementation, the beam measurement results corresponding to the at most p beams belong to the subset of the beam measurement results corresponding to the n beams can be because the beam measurement results corresponding to the m beams are selected from the beam measurement results corresponding to the n beams with priority to the beam measurement results greater than the first threshold.

[0094] Branch Two

[0095] In Branch Two, the beam measurement results corresponding to the at most p beams belong to the subset of the beam measurement results corresponding to the n beams, and the weighting factor associated with each of the beam measurement results corresponding to the at most p beams can be equal to the reciprocal of the number of beams contained in the at most p beams. The cell level measurement result corresponding to the first cell at the first time instance determined based on the weighted average of the beam measurement results corresponding to the at most p beams is equivalent to the cell level measurement result corresponding to the first cell at the first time instance determined based on the linear average of the beam measurement results corresponding to the at most p beams, and n and p are positive integers.

[0096] In Branch Two, assuming that the beam measurement results corresponding to the at most p beams contain the beam measurement results of y2 beams, where y2 is a positive integer less than or equal to p, the weighting factor associated with each of the beam measurement results corresponding to the y2 beams is equal to 1 / y2, and at this time, the cell level measurement result corresponding to the first cell at the first time instance is determined based on the following public formula: (the sum of the y2 beam measurement results) divided by y2.

[0097] In an implementation, the beam measurement results corresponding to the at most p beams belong to the subset of the beam measurement results corresponding to the n beams can be because the beam measurement results corresponding to the at most k beams contained in the third beam set are all contained in the beam measurement results corresponding to the n beams, the beam measurement results corresponding to the at most k beams contained in the third beam set are the beam measurement results corresponding to the m beams and the beam measurement results corresponding to the n beams greater than the first threshold, and k is a positive integer less than or equal to p.

[0098] In another implementation, the beam measurement results corresponding to the at most p beams belong to the subset of the beam measurement results corresponding to the n beams can be because the beam measurement results corresponding to the m beams with the priority to select are all less than or equal to the first threshold, and at this time, only the beam measurement results greater than the first threshold can be selected from the beam measurement results corresponding to the n beams.

[0099] Branch Three

[0100] In branch three, z2 beam measurement results in the beam measurement results corresponding to the maximum p beam pairs belong to the beam measurement results corresponding to the m beam pairs, and a weighting factor associated with each of the z2 beam measurement results is equal to (1-w) divided by z2 or w divided by z2, y2 beam measurement results in the beam measurement results corresponding to the maximum p beam pairs belong to the beam measurement results corresponding to the n beam pairs, and a weighting factor associated with each of the y2 beam measurement results is equal to w divided by y2 or (1-w) divided by y2, where w is a real number in the range of (0, 1), z2, y2, m, n, and p are positive integers, and a cell-level measurement result corresponding to the first cell at the first time is determined based on any one of the following formulas: [(sum of the z2 beam measurement results) multiplied by (1-w) divided by z2] + [(sum of the y2 beam measurement results) multiplied by w divided by y2]; or [(sum of the z2 beam measurement results) divided by z2 multiplied by (1-w)] + [(sum of the y2 beam measurement results) divided by y2 multiplied by w]; or [(sum of the z2 beam measurement results) multiplied by w divided by z2] + [(sum of the y2 beam measurement results) multiplied by (1-w) divided by y2]; or [(sum of the z2 beam measurement results) divided by z2 multiplied by w] + [(sum of the y2 beam measurement results) divided by y2 multiplied by (1-w)]. The w is used by the terminal device to calculate the cell-level measurement result.

[0101] In an implementation, if the third beam set contains part of the beam measurement results corresponding to the best k beam measurement results in the beam measurement results corresponding to the beam pairs (k is a positive integer less than or equal to p), the part of the beam measurement results is contained in the beam measurement results corresponding to the m beam pairs, and the other part of the beam measurement results is contained in the beam measurement results corresponding to the n beam pairs, the situation involved in branch three can occur, the third beam set contains the beam measurement results corresponding to the m beam pairs and the beam measurement results corresponding to the n beam pairs whose beam measurement results are greater than the first threshold value.

[0102] In another implementation, if the number of beams whose beam measurement results are greater than the first threshold value in the beam measurement results corresponding to the m beam pairs is less than p, and there is at least one beam whose beam measurement result is greater than the first threshold value in the beam measurement results corresponding to the n beam pairs, although the maximum p beam measurement results preferentially select the beam measurement results corresponding to the beams whose beam measurement results are greater than the first threshold value in the beam measurement results corresponding to the m beam pairs, but due to the insufficient number of beams whose beam measurement results are greater than the first threshold value in the beam measurement results corresponding to the m beam pairs, it is still necessary to select the beam measurement results corresponding to the beams whose beam measurement results are greater than the first threshold value from the beam measurement results corresponding to the n beam pairs as a supplement, that is, the situation involved in the above branch three occurs.

[0103] It should be noted that the terminal device can obtain the value of w in any of the following manners: a protocol default manner, receiving a system broadcast message sent by the network device, and receiving special signaling sent by the network device.

[0104] For example, the network device can send second configuration information to the terminal device, where the second configuration information is used to indicate the value of w, and the w is used by the terminal device to calculate the cell-level measurement result.

[0105] Adjusting the proportion of the predicted beam measurement result in the calculation of the cell-level measurement result by the parameter w helps to reduce the measurement prediction error caused by the use of the prediction function in the calculation of the cell-level measurement result.

[0106] Compared with the scheme based on linear average, the scheme based on weighted average is more flexible. Once the beam measurement result corresponding to the maximum p beams selected by the terminal device according to the rule contains both the beam measurement result obtained in the actual measurement process and the beam measurement result obtained in the prediction process, the weight values of the beam measurement result obtained in the actual measurement process and the beam measurement result obtained in the prediction process are the same in the scheme based on linear average; in the scheme based on weighted average, the weight value of the beam measurement result obtained in the actual measurement process and the weight value of the beam measurement result obtained in the prediction process in the beam measurement result corresponding to the maximum p beams can be the same or different, and whether they are the same or different can be adjusted by the parameter w, so the scheme based on weighted average is more flexible than the scheme based on linear average.

[0107] In some embodiments, if the beam measurement result corresponding to the m beams and the beam measurement result corresponding to the n beams with the highest beam measurement result are less than or equal to the first threshold value, the cell-level measurement result corresponding to the first cell at the first time is determined based on the maximum value of the beam measurement result corresponding to the m beams and the beam measurement result corresponding to the n beams. That is, in the case where all the beam measurement results (including actual measurement and prediction) that can be used to determine the cell-level measurement result are less than or equal to the first threshold value, the terminal device can determine the cell-level measurement result based on the maximum value of the actual beam measurement result and the predicted beam measurement result. It should be noted that whether the terminal device distinguishes the actual beam measurement result and the predicted beam measurement result when calculating the cell-level measurement result corresponding to the first cell, this scheme can be used.

[0108] In some embodiments, if the beam measurement result corresponding to the beam with the highest beam measurement result among the m beam measurement results is less than or equal to the first threshold value, the cell-level measurement result of the first cell at the first time is determined based on the maximum value of the beam measurement results among the m beam measurement results. That is, in the case where all the actually measured beam measurement results are less than or equal to the first threshold value, the case where the predicted beam measurement result is not considered, and the cell-level measurement result is determined based on the maximum value of the actually measured beam measurement results. This embodiment determines how to calculate the cell-level measurement result based on the actually measured beam measurement result, which is more accurate.

[0109] In the cell reselection scenario, after the terminal device obtains the cell-level measurement results of the serving cell and the neighbor cell, it needs to further evaluate whether to perform cell reselection, and further determine the reselection target cell when it is determined that the cell reselection condition is met.

[0110] In some embodiments, the terminal device can determine the R value of the first cell, where the first cell can be a serving cell or a neighbor cell of the terminal device. The terminal device can determine the reselection target cell from the at least two first cells according to the first rule and the R value of the at least two first cells.

[0111] As a possible implementation, in the case where there are at least two first cells that need to be sorted or evaluated using the R criterion, the terminal device can determine the reselection target cell according to the first rule.

[0112] Optionally, the scenario where there are at least two first cells that need to be sorted or evaluated using the R criterion can include any one of scenarios three to five.

[0113] Scenario three: using the R criterion to sort the same frequency cells or the inter-frequency cells with the same frequency point priority as the serving cell, that is, the scenario where there are at least two first cells belonging to the same frequency cells of the serving cell or belonging to the inter-frequency cells with the same frequency point priority as the serving cell.

[0114] Scenario four: using the R criterion to sort the inter-frequency cells with high priority, that is, the scenario where there are at least two first cells belonging to the inter-frequency cells with high priority.

[0115] Scenario five: using the R criterion to sort the inter-frequency cells with low priority, that is, the scenario where there are at least two first cells belonging to the inter-frequency cells with low priority.

[0116] It should be noted that the concepts of same frequency or inter-frequency in scenarios three to five are relative to the frequency point of the current serving cell of the terminal device.

[0117] It should be noted that, in some embodiments, cells participating in the R-criterion ranking also need to meet at least one of the following constraints: the new cell's quality must be better than the current cell's for a longer period than Treselection. NR If the terminal device is in a non-normal mobile state, the Treselection parameter needs to be considered. NR With Q hyst Scaling is performed; the terminal device remains in the original cell for more than 1 second.

[0118] The following examples illustrate two ways to implement the first rule.

[0119] Implementation Method 1

[0120] The first rule may include: if the network device does not configure the first parameter, the terminal device can reselect to the cell with the highest R ranking; and / or, if the network device configures the first parameter, the terminal device can reselect to a cell with an R value belonging to [R...]. best - First parameter, R best The cell with the most beam measurement results above the first threshold within the range and corresponding cell association beam measurement results. Where R best This is the R-value corresponding to the cell with the highest R-value among the cells evaluated by the R-criterion. The first parameter can be, for example, the rangeToBestCell parameter in related technologies.

[0121] The beam measurement results associated with the corresponding cell include both the measured beam measurement results and the predicted beam measurement results associated with the cell, and the implementation does not make any additional distinction between the two.

[0122] In implementation method one, the aforementioned at least two first cells do not distinguish between first-type cells and second-type cells. Specifically, for the first-type cells, a portion of the beam measurement results are obtained by the terminal device through an actual measurement process, while the remaining portion is obtained by the terminal device through a measurement prediction process; for the second-type cells, all beam measurement results are obtained by the terminal device through an actual measurement process.

[0123] The first implementation does not distinguish between measured beam measurement results and predicted beam measurement results. It only considers the magnitude of the beam measurement results to determine the number of beams and reuses the methods for determining the target cell in related technologies as much as possible. Therefore, this implementation method is relatively simple to implement.

[0124] Implementation Method Two

[0125] If the network device does not configure the first parameter, the terminal device can reselect to the cell with the highest R value; if the network device configures the first parameter and all the at least two first cells are first type cells, the terminal device can reselect to the cell with the highest R value and the largest number of beams with beam measurement results higher than the first threshold value in the corresponding cell associated beam measurement results; if the network device configures the first parameter and the at least two first cells are not all first type cells, the terminal device can reselect to the cell with the highest R value and the largest number of beams with beam measurement results higher than the first threshold value in the corresponding cell associated beam measurement results. best - the first parameter, R best ] and the largest number of beams with beam measurement results higher than the first threshold value in the corresponding cell associated beam measurement results; if the network device configures the first parameter and the at least two first cells are not all first type cells, the terminal device can reselect to the cell with the highest R value and the largest number of beams with beam measurement results higher than the first threshold value in the corresponding cell associated beam measurement results. best - the first parameter, R best ] and the largest number of beams with beam measurement results higher than the first threshold value in the corresponding cell associated beam measurement results. Wherein, R best is the R value corresponding to the cell with the highest R value in the R criterion evaluation, and the beam measurement results of a part of beams corresponding to the first type cell are obtained by the terminal device through an actual measurement process, and the beam measurement results of another part of beams are obtained by the terminal device through a measurement prediction process. The first parameter may, for example, be a rangeToBestCell parameter in related technologies.

[0126] The above-mentioned corresponding cell associated beam measurement results simultaneously include actual measurement beam measurement results and predicted beam measurement results associated with the cell.

[0127] The second implementation distinguishes between first type cells and second type cells. The number of good beams (beam measurement results greater than the first threshold value) in the actual measurement beam measurement results is given priority. That is, if at least two cells participate in R criterion ranking, for the cells with R values in a range, the cell with the largest number of good beams in the actual measurement beam measurement results is given priority for reselection, and the number of good beams in the predicted beam measurement results is considered secondarily or not considered in the evaluation. Therefore, the second implementation can avoid relying on the number of good beams in the predicted beam measurement results to determine the reselection target cell as much as possible, so that the terminal device measurement overhead can be saved by using the prediction function, and the situation of performance degradation of cell reselection caused by excessive reliance on predicted beam measurement results to determine the reselection target cell can be avoided.

[0128] In some embodiments, for example, in the first implementation or the second implementation, the plurality of first cells satisfy that the R values belong to the range [R best - the first parameter, R best ] and the number of beams with beam measurement results higher than the first threshold value in the corresponding cell associated actual measurement beam measurement results is the same, or the plurality of first cells satisfy that the R values belong to the range [R best - the first parameter, R bestthe first threshold value. In this case, the terminal device can reselect to the cell with the highest R value among the plurality of first cells.

[0129] Fig. 3 is a schematic flowchart of another wireless communication method according to an embodiment of the present application. The method shown in Fig. 3 can comprise step S310.

[0130] At step S310, the terminal device receives first configuration information sent by the network device. The first configuration information comprises a first parameter and / or a second parameter. The first parameter is used to indicate a set of beams that need to be measured by the terminal device, and the second parameter is used to indicate a set of beams that need to be predicted by the terminal device.

[0131] It should be noted that the method shown in Fig. 3 can be implemented alone or in combination with the method shown in Fig. 2. For example, the first set of beams in step S210 is the set of beams that need to be measured by the terminal device indicated by the first parameter included in the first configuration information, or the first set of beams is a subset of the set of beams that need to be measured by the terminal device indicated by the first parameter included in the first configuration information. For another example, the second set of beams in step S210 is the set of beams that need to be predicted by the terminal device indicated by the second parameter included in the first configuration information, or the second set of beams is a subset of the set of beams that need to be predicted by the terminal device indicated by the second parameter included in the first configuration information.

[0132] Exemplarily, based on the set of beams that need to be measured by the terminal device, the beam measurement results corresponding to the m beams associated with the first cell at a first time obtained according to an actual measurement process are the beam measurement results corresponding to the beams included in the first set of beams, based on the set of beams that need to be predicted by the terminal device, the beam measurement results corresponding to the n beams associated with the first cell at the first time obtained according to a prediction process are the beam measurement results corresponding to the beams included in the second set of beams, and the beam measurement results corresponding to the beams included in the first set of beams and / or the beam measurement results corresponding to the beams included in the second set of beams are used to determine a cell-level measurement result corresponding to the first cell; wherein the first cell is a serving cell of the terminal device or a neighbor cell of the terminal device, m and n are both positive integers, and the first time is any one of the times at which the terminal device performs the measurement process.

[0133] In one implementation, the first configuration information comprises the first parameter and the second parameter. This way can make it very clear for the terminal device to measure which beams and predict which beams, and the behavior of the terminal device is simple.

[0134] In another implementation, the first configuration information comprises the first parameter or the second parameter.

[0135] In some embodiments, if the first configuration information comprises the first parameter, the first parameter can be configured in frequency point granularity or cell granularity. If the first parameter is configured in frequency point granularity, the first configuration information further comprises frequency point indication information; if the first parameter is configured in cell granularity, the first configuration information further comprises frequency point indication information and PCI information.

[0136] In some embodiments, if the first configuration information comprises the second parameter, the second parameter can be configured in frequency point granularity or cell granularity. If the second parameter is configured in frequency point granularity, the first configuration information further comprises frequency point indication information; if the second parameter is configured in cell granularity, the first configuration information further comprises frequency point indication information and PCI information.

[0137] In some embodiments, if the first configuration information comprises the first parameter and the second parameter, the first parameter and the second parameter are associated with the same frequency point indication information or the same frequency point indication information and PCI information.

[0138] Compared with the configuration in cell granularity, the configuration of the first parameter and / or the second parameter in frequency point granularity can make the implementation of the terminal device simple, because the terminal device can avoid measuring some cells at one time and predicting some cells at another time.

[0139] The method embodiments of the present application are described in detail above, and the device embodiments of the present application are described in detail below. It should be understood that the description of the method embodiments corresponds to the description of the device embodiments, and therefore, the parts not described in detail can be referred to the method embodiments.

[0140] FIG. 4 is a schematic structural diagram of a terminal device 400 according to an embodiment of the present application. The terminal device 400 can comprise a determination unit 410.

[0141] The determination unit 410 can be configured to determine a cell-level measurement result corresponding to a first cell based on a first set of beam measurement results corresponding to beams and / or a second set of beam measurement results corresponding to beams, wherein the first set of beam measurement results corresponding to the beams is a first set of beam measurement results corresponding to m beams associated with the first cell at a first time obtained by the terminal device according to an actual measurement process, and the second set of beam measurement results corresponding to the beams is a second set of beam measurement results corresponding to n beams associated with the first cell at the first time obtained by the terminal device according to a measurement prediction process, wherein the first cell is a serving cell of the terminal device or a neighbor cell of the terminal device, m and n are positive integers, and the first time is any one of time points during which the terminal device performs the measurement process.

[0142] In some embodiments, the cell level measurement result corresponding to the first cell at the first time instance is determined based on at most p beam measurement results, wherein any one of the at most p beam measurement results belongs to the m beam measurement results or belongs to the n beam measurement results, and each of the at most p beam measurement results is greater than the first threshold, and the p is a positive integer.

[0143] In some embodiments, if there is at least one beam measurement result greater than the first threshold among the m beam measurement results, the cell level measurement result corresponding to the first cell at the first time instance is determined based on at most p beam measurement results.

[0144] In some embodiments, the at most p beam measurement results are preferentially selected from the m beam measurement results with beam measurement results greater than the first threshold.

[0145] In some embodiments, if the number of beams with beam measurement results greater than the first threshold among the m beam measurement results is greater than or equal to the p, or if the number of beams with beam measurement results greater than the first threshold among the m beam measurement results is less than the p and the number of beams with beam measurement results greater than the first threshold among the n beam measurement results is 0, the cell level measurement result corresponding to the first cell at the first time instance is determined based on at most p beam measurement results among the m beam measurement results, wherein each of the at most p beam measurement results is greater than the first threshold.

[0146] In some embodiments, if the number of beams with beam measurement results greater than the first threshold among the m beam measurement results is less than the p and there is at least one beam measurement result greater than the first threshold among the n beam measurement results, the cell level measurement result corresponding to the first cell at the first time instance is determined based on z1 beam measurement results among the m beam measurement results and y1 beam measurement results among the n beam measurement results, wherein each of the z1 beam measurement results is greater than the first threshold, the number of beams with beam measurement results greater than the first threshold among the m beam measurement results is z1, each of the y1 beam measurement results is greater than the first threshold, and (z1+y1) is not greater than the p, and the z1 and y1 are positive integers.

[0147] In some embodiments, if the beam measurement corresponding to the beam with the highest beam measurement among the beam measurements corresponding to the m beams is less than or equal to the first threshold value but there exists at least one beam measurement greater than the first threshold value among the beam measurements corresponding to the n beams, the cell level measurement corresponding to the first cell at the first time instance is determined based on the p largest beam measurements among the beam measurements corresponding to the n beams, wherein the p largest beam measurements are all greater than the first threshold value, and wherein p is a positive integer.

[0148] In some embodiments, if there exists at least one beam measurement greater than the first threshold value among the beam measurements corresponding to the m beams and the beam measurements corresponding to the n beams, the cell level measurement corresponding to the first cell at the first time instance is determined based on the p largest beam measurements, which belong to a third beam set containing a subset of beam measurements, wherein the third beam set containing beam measurements are the beam measurements greater than the first threshold value among the beam measurements corresponding to the m beams and the beam measurements corresponding to the n beams, and wherein p is a positive integer.

[0149] In some embodiments, the cell level measurement corresponding to the first cell at the first time instance is determined based on a linear average of the p largest beam measurements.

[0150] In some embodiments, the cell level measurement corresponding to the first cell at the first time instance is determined based on a weighted average of the p largest beam measurements.

[0151] In some embodiments, the p largest beam measurements belong to a subset of the beam measurements corresponding to the m beams, and each of the p largest beam measurements is associated with a weighting factor equal to the inverse of the number of beams contained in the p largest beams.

[0152] In some embodiments, the p largest beam measurements belong to a subset of the beam measurements corresponding to the n beams, and each of the p largest beam measurements is associated with a weighting factor equal to the inverse of the number of beams contained in the p largest beams.

[0153] In some embodiments, z2 beam measurement results among the at most p beam measurement results correspond to the m beam measurement results, and each of the z2 beam measurement results is associated with a weighting factor equal to (1-w) divided by z2 or w divided by z2, y2 beam measurement results among the at most p beam measurement results correspond to the n beam measurement results, and each of the y2 beam measurement results is associated with a weighting factor equal to w divided by y2 or (1-w) divided by y2, where w is a real number in the range of (0, 1), z2, y2, m, n, and p are positive integers, and the cell-level measurement result of the first cell at the first time is determined based on any one of the following formulas: [(sum of the z2 beam measurement results) multiplied by (1-w) divided by z2] + [(sum of the y2 beam measurement results) multiplied by w divided by y2]; or [(sum of the z2 beam measurement results) divided by z2 multiplied by (1-w)] + [(sum of the y2 beam measurement results) divided by y2 multiplied by w]; or [(sum of the z2 beam measurement results) multiplied by w divided by z2] + [(sum of the y2 beam measurement results) multiplied by (1-w) divided by y2]; or [(sum of the z2 beam measurement results) divided by z2 multiplied by w] + [(sum of the y2 beam measurement results) divided by y2 multiplied by (1-w)].

[0154] In some embodiments, the terminal device obtains the value of w in any one of the following ways: a protocol default way, receiving a system broadcast message sent by a network device, and receiving dedicated signaling sent by a network device, where w is used by the terminal device to calculate a cell-level measurement result.

[0155] In some embodiments, if the highest beam measurement result among the m beam measurement results and the n beam measurement results is less than or equal to a first threshold value, the cell-level measurement result of the first cell at the first time is determined based on the maximum value of the beam measurement results among the m beam measurement results and the n beam measurement results.

[0156] In some embodiments, if the highest beam measurement result among the m beam measurement results is less than or equal to a first threshold value, the cell-level measurement result of the first cell at the first time is determined based on the maximum value of the beam measurement results among the m beam measurement results.
