If the signal reception quality is greater than the signal reception quality of the serving cell (or the signal reception quality of the neighboring cell is greater than the first quality threshold), then it is determined to perform cell reselection.
在一些实施例中，在服务小区和邻小区的优先级相同的情况下，终端确定重选至邻小区中的目标小区，其中，目标小区为：R值大于该服务小区且R值最大的邻小区，且该邻小区的信号接收质量大于服务小区的信号接收质量(或者，邻小区的信号接收质量大于第一质量门限)。In some embodiments, when the priority of the serving cell and the neighboring cell is the same, the terminal determines to reselect to the target cell among the neighboring cells, where the target cell is: the neighbor with the R value greater than the serving cell and the largest R value. cell, and the signal reception quality of the neighboring cell is greater than the signal reception quality of the serving cell (or the signal reception quality of the neighboring cell is greater than the first quality threshold).

In this way, the network environment can be considered in a balanced manner, allowing the terminal to reselect the best cell. This can prevent poor signal strength or poor signal quality from affecting the service quality of the terminal, thereby improving user experience.
为了进一步解释本公开任意实施例，以下提供几个具体实施例。In order to further explain any embodiments of the present disclosure, several specific examples are provided below.
本公开实施例提供一种小区重选方法，该方法由终端执行，结合RSRP与RSRQ/SINR进行小区重选，该方法可以包括：Embodiments of the present disclosure provide a cell reselection method, which is executed by a terminal and combines RSRP and RSRQ/SINR to perform cell reselection. The method may include:
1、同频及同优先级异频重选1. Same frequency and same priority inter-frequency reselection
针对小区重选涉及S准则和R准则。Cell reselection involves the S criterion and the R criterion.
S准则为：Srxlev＞0并且Squal＞0。其中，Srxlev为小区选择信号接收强度，Squal为小区选择信号接收质量。终端进行小区重选需要满足S准则。The S criteria are: Srxlev>0 and Squal>0. Among them, Srxlev is the cell selection signal reception strength, and Squal is the cell selection signal reception quality. The terminal needs to meet the S criterion for cell reselection.
R准则为：The R criterion is:
Rs＝Qmeas,s+Qhyst-QoffsettempRs＝Qmeas,s+Qhyst-Qoffsettemp
Rn＝Qmeas,n-Qoffset-QoffsettempRn＝Qmeas,n-Qoffset-Qoffsettemp
其中，Rs为服务小区的R值，Rn为邻小区的R值，Qmeas,s为服务小区的RSRP测量值；Qmeas,n为邻小区的RSRP测量值，Qhyst为小区重选滞后值，Qoffsettemp为临时偏置值，Qoffset为偏置值。Among them, Rs is the R value of the serving cell, Rn is the R value of the neighboring cell, Qmeas,s is the RSRP measurement value of the serving cell; Qmeas,n is the RSRP measurement value of the neighboring cell, Qhyst is the cell reselection hysteresis value, Qoffsettemp is Temporary offset value, Qoffset is the offset value.
对于同频小区，如果配置了Qoffsets,n，则Qoffset为Qoffsets,n；没有配置Qoffsets,n时，则Qoffset为0。对于异频小区，如果配置了Qoffsets,n，则Qoffset为Qoffsets,n+Qoffsetfrequency，否则Qoffset为Qoffsetfrequency。For co-frequency cells, if Qoffsets,n is configured, Qoffset is Qoffsets,n; if Qoffsets,n is not configured, Qoffset is 0. For inter-frequency cells, if Qoffsets,n is configured, Qoffset is Qoffsets,n+Qoffsetfrequency, otherwise Qoffset is Qoffsetfrequency.
只有下列条件满足时才会重选到新小区：A new community will be reselected only when the following conditions are met:
TreselectionRAT时间内新小区满足小区重选准则；The new cell meets the cell reselection criteria within the TreselectionRAT time;
UE在当前小区驻留超过1秒钟；The UE stays in the current cell for more than 1 second;
如果没有配置rangeToBestCell参数，UE应该重选到最高排序的小区。If the rangeToBestCell parameter is not configured, the UE should reselect the highest ranked cell.
如果配置了rangeToBestCell参数，UE应该在根据R准则排序的最高rangeToBestCell个小区中，选择高于门限最多波束的小区。如果这样的小区有多个(高于门限的波束数量相同)，则重选到最高排序的小区。门限为absThreshSS-BlocksConsolidation。If the rangeToBestCell parameter is configured, the UE should select the cell with the most beams above the threshold among the highest rangeToBestCell cells sorted according to the R criterion. If there are multiple such cells (the number of beams above the threshold is the same), the highest ranked cell will be reselected. The threshold is absThreshSS-BlocksConsolidation.
如果配置了rangeToBestCell参数，但是没有配置absThreshSS-BlocksConsolidation参数，UE认为该频点的每个小区有一个波束高于门限。If the rangeToBestCell parameter is configured, but the absThreshSS-BlocksConsolidation parameter is not configured, the UE considers that one beam in each cell of the frequency point is higher than the threshold.
结合采用R准则对小区进行重选排序(或者RSRP的Rank排名方式重选)，本实施例将邻小区的RSRQ/SINR也考虑进来，即同时保证：Combined with the use of the R criterion to reselect and sort cells (or reselect according to the Rank ranking method of RSRP), this embodiment also takes the RSRQ/SINR of neighboring cells into consideration, that is, ensuring at the same time:
ServingCell_RSRQ/SINR<NeighborCell_RSRQ/SINR+Offset_RSRQ/SINR；ServingCell_RSRQ/SINR<NeighborCell_RSRQ/SINR+Offset_RSRQ/SINR;
