进一步地，可以根据同频邻小区的测量结果，结合所述小区黑名单，确定重选到哪个小区。
具体地，所述终端设备可以在测量的至少一个同频邻小区中确定候选同频邻小区，其中，所述候选同频邻小区不属于所述小区黑名单。也就是说，若同频邻小区属于小区黑名单，则不选择该同频邻小区作为候选的重选小区，即候选同频邻小区包括低负荷的小区。当然，所述候选同频邻小区也不包括所述服务小区，避免终端设备重选失败。
进一步地，所述终端设备可以在所述候选同频邻小区中选择重选的目标小区。
作为一个实施例，所述终端设备可以将所述候选同频邻小区的测量结果按照从高到低的顺序进行排序，所述终端设备可以选择排序最高的同频邻小区作为所述目标小区。排序最高的小区可以认为是候选同频邻小区中信道质量最优的邻小区。
因此，在进行小区重选时，所述终端设备可以在低负荷小区中选择信道质量最优的小区作为重选的目标小区，有利于实现小区的负载均衡，并且能够保证终端设备的可靠的数据传输。
可选地，在另一些实施例中，所述终端设备也可以在所述候选同频邻小区中选择测量结果大于一定阈值的小区作为所述目标小区，本申请并不限于此。
可选地，所述服务小区的测量结果可以根据所述服务小区发送的下行参考信号的测量结果确定。
可选地，所述下行参考信号例如包括但不限于以下中的至少一项：同步信号块(Synchronization Signal Block，SSB)、信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)、解调参考信号(Demodulation Reference Signal,DMRS)，主同步信号(Sidelink Primary Synchronization Signal，PSS)和辅同步信号(Secondary Synchronization Signal，SSS)等；同步信号包括PSS和SSS；解调参考信号包括用于物理下行共享信道(Physical Downlink Shared Channel，PDSCH)、物理下行控制信道(Physical Downlink Control Channel，PDCCH)和物理广播信道(Physical Broadcast Channel，PBCH)解调的DMRS。

可选地，在一些实施例中，所述服务小区不满足所述同频测量启动门限所述服务小区的S值大于所述同频测量启动门限，其中，所述S值可以指小区选择中的Srxlev(S准则)，具体实现可以参考相关技术的实现，这里不再赘述。
场景2：异频场景
在异频场景中，所述测量启动门限可以包括异频测量启动门限。
在相关技术中，若服务小区不满足所述异频测量启动门限，所述终端设备不启动异频邻小区测量，也就是不能重选到其他小区，此情况下，若服务小区的负荷较大，可能影响该服务小区下的用户的体验。
在本申请实施例中，所述终端设备可以在服务小区不满足所述异频测量启动门限，并且所述服务小区属于所述小区黑名单，所述终端设备开启异频邻小区测量，获取异频邻小区的测量结果。
在另一些实施例中，所述终端设备可以在所述服务小区属于所述小区黑名单时，开启异频邻小区测量，即不管服务小区是否满足所述异频测量启动门限；
或者，在另一些实施例中，所述终端设备也可以在服务小区满足所述异频测量启动门限时，开启异频邻小区测量。
可选地，在一些实施例中，所述服务小区不满足所述异频测量启动门限可以参考小区重选准则中的相关实现，这里不再赘述。
进一步地，可以根据异频邻小区的测量结果，结合所述小区黑名单，确定重选到哪个异频小区。
具体地，所述终端设备可以在测量的至少一个异频邻小区中确定候选异频邻小区，其中，所述候选异频邻小区不属于所述小区黑名单。也就是说，若异频邻小区属于小区黑名单，则不选择该异频邻小区作为候选的重选小区，即候选异频邻小区包括低负荷的小区。
进一步地，所述终端设备可以在所述候选异频邻小区中选择重选的目标小区。
在一些实施例中，所述终端设备可以根据所述候选异频邻小区的优先级，在所述候选异频邻小区中确定所述目标小区。
情况1：所述候选异频邻小区的优先级和所述服务小区的优先级相同。此情况类似于同频邻小区的小区重选场景。
作为一个示例，所述终端设备可以将所述候选异频邻小区的测量结果按照从高到低的顺序进行排序，所述终端设备可以选择排序最高的异频邻小区作为所述目标小区。排序最高的小区可以认为是候选异频邻小区中信道质量最优的邻小区。
作为另一示例，所述终端设备也可以在所述候选异频邻小区中选择测量结果大于一定阈值的小区作为所述目标小区，本申请并不限于此。
情况2：所述候选异频邻小区的优先级高于所述服务小区的优先级。
此情况下，所述终端设备可以在所述候选异频邻小区中选择测量结果满足小区选择准则的异频邻小区作为所述目标小区。这里的小区选择准则也称为小区重选准则，具体实现可以参考相关技术，这里不再赘述。
可选地，作为一个示例，所述终端设备可以在所述候选异频邻小区中选择优先级最高的异频邻小区作为所述目标小区。
情况3：所述候选异频邻小区的优先级低于所述服务小区的优先级。
作为一个示例，在所述候选异频邻小区中选择测量结果满足低优先级重选门限的异频邻小区作为所述目标小区。
作为再一示例，所述终端设备可以在服务小区的测量结果小于等于一门限值(记为ThrshServLow)，并且低优先级的异频邻小区的测量结果高于或等于一门限值(记为ThreshXLow)时，选择所述低优先级的异频邻小区作为所述目标小区。
可选地，在上述实施例中，所述终端设备除了结合小区的测量结果进行小区重选，还可以进一步结合小区的持续时间，例如，对于低优先级的小区重选，除了需要低优先级的异频邻小区的测量结果大于低于门限值之外，还需要该测量结果的持续时间超过一定的时间阈值。
因此，在进行小区重选时，所述终端设备可以在低负荷小区中选择优先级较高的小区作为重选的目标小区，有利于实现小区的负载均衡，并且能够保证终端设备的可靠的数据传输。
以下结合图3和图4，说明上述两种场景的具体流程。
对于同频场景，如图3所示，可以包括如下步骤：
S301，终端设备驻留在服务小区；
S302，终端设备确定是否存在同频邻小区；
若存在同频邻小区，则流程进行到S303。
S303，判断是否服务小区不满足同频测量启动门限且服务小区属于小区黑名单。
若是，则执行S304。否则不开启同频邻小区测量。
S304，终端设备开启同频邻小区测量。
S305，判断测量的同频邻小区是否属于小区黑名单。
S306，在不属于黑名单的同频邻小区中选择目标小区。
也就是说，服务小区的测量结果不参与小区重选。
作为一个具体示例，所述终端设备可以将所述同频邻小区的测量结果按照从高到低的顺序进行排序，所述终端设备可以选择排序最高的同频邻小区作为所述目标小区。即所述终端设备可以重选到排序最高的邻小区。
对于异频场景，如图4所示，可以包括如下步骤：
S401，终端设备驻留在服务小区；
S402，终端设备确定是否存在异频邻小区，并且异频邻小区的优先级不高于服务小区的优先级；
若是，流程进行到S403。
S403，判断是否服务小区不满足同频测量启动门限且服务小区属于小区黑名单。
若是，则执行S404。否则不开启异频邻小区测量。
S404，终端设备开启异频邻小区测量。
S405，判断测量的异频邻小区是否属于小区黑名单。
S406，在不属于黑名单的异频邻小区中，判断异频邻小区的优先级和服务小区的优先级是否相同。
若相同，执行S407，否则执行S408。
S407，在不属于黑名单的异频邻小区中，根据这些异频邻小区的测量结果选择所述目标小区。
也就是说，服务小区的测量结果不参与小区重选。
作为一个具体示例，所述终端设备可以将所述同频邻小区的测量结果按照从高到低的顺序进行排序，所述终端设备可以选择排序最高的同频邻小区作为所述目标小区。即所述终端设备可以重选到排序最高的邻小区。
S408，根据异频邻小区的优先级和优先级重选门限，选择目标小区。
作为一个示例，可以选择优先级满足低优先级重选门限的异频邻小区作为所述目标小区。
图5是根据本申请实施例的无线通信的方法500的示意性流程图，如图5所示，该方法500可以包括但不限于如下内容：
S510，若终端设备的服务小区属于小区黑名单，并且邻小区不属于所述小区黑名单，所述终端设备将所述服务小区的测量结果修改为第一值，其中，所述第一值小于或等于特定阈值；
S520，所述终端设备根据所述第一值和邻小区的测量结果，进行测量上报。
可选地，在一些实施例中，所述小区黑名单可以是根据小区负荷情况确定的黑名单，例如，小区黑名单包括高负荷的小区，或者说，负荷高于一定阈值的小区，或者包括多个小区中负荷排名靠前的小区等。
可选地，小区的负荷情况可以是根据小区的历史接入用户数量，承载的业务量等进行判断，本申请并不限于此。
在一些实施例中，小区属于小区黑名单可以认为该小区的负荷较大，需要进行负荷均衡。
可选地，所述小区黑名单可以是网络设备配置的，或者也可以是从第三设备获取的，例如从服务器获取。
例如，网络设备可以通过广播消息发送所述小区黑名单。或者，所述网络设备也可以通过其他消息或信令发送所述小区黑名单，例如无线资源控制(Radio Resource Control，RRC)信令、媒体接入控制单元(Media Access Control Control Element，MAC CE)等，但本申请并不限于此。
本申请实施例在进行小区切换时考虑小区黑名单，有利于避开小区黑名单中的小区，切换到低负荷的小区，从而实现小区的负载均衡，提升***性能。
在相关技术中，若服务小区的信道质量较高，通常不会触发测量上报，也就不能触发小区切换，此情况下，若服务小区的负荷较大，可能影响该服务小区下的用户的体验。
服务小区属于小区黑名单，并且邻小区不属于所述小区黑名单，表示服务小区的负荷较重，邻小区的负荷较轻，此情况下，若服务小区的信道质量较高，终端设备不会进行测量上报，在本申请实施例中，所述终端设备可以将所述服务小区的测量结果修改为一个较低值，例如第一值，该第一值可以小于或等于特定阈值，小于该特定阈值的测量结果会触发测量上报。
可选地，所述特定阈值是小区测量结果的最小值，例如-128dB，或者所述特定阈值是预定义的，或者，所述特定阈值是网络设备配置的。
进一步地，所述终端设备可以根据修改后的测量结果，即所述第一值进行测量事件的判断，例如进行测量事件A2的判断，即判断所述第一值是否低于一个阈值，由于所述第一值足够低，因此，会 触发测量事件A2的上报。
进一步地，网络设备可以给终端设备配置进行测量事件A3和A5上报的相关配置。例如，用于测量事件A3的第一偏移量，以及用于测量事件A5的两个阈值。
从而所述终端设备可以根据修改后的所述服务小区的测量结果以及邻小区的测量结果，进行测量事件A3或A5的判决。由于所述第一值足够低，因此，一般会触发测量事件A3或A5的上报。
例如，若所述邻小区的测量结果比所述第一值高第一偏移量，所述终端设备向网络设备上报测量事件A3；或者若所述邻小区的测量结果高于第二阈值，并且所述低于值低于第三阈值，所述终端设备向网络设备上报测量事件A5。
进一步地，所述网络设备可以根据终端设备上报的测量事件，为终端设备选择切换的目标小区，从而能够将所述终端设备从高负荷的服务小区切换至低负荷的邻小区，从而实现小区的负载均衡，提升***性能。
以下结合图6，说明该无线通信地方法的具体流程。
如图6所示，可以包括如下步骤：
S601，网络设备给终端设备发送无线资源控制(Radio Resource Control,RRC)连接重配消息。
S602，网络设备给终端设备发送测量配置。
S603，所述终端设备确定服务小区属于小区黑名单，并且邻小区不属于小区黑名单。
进一步地，在S604中，所述终端设备将所述服务小区的测量结果修改为第一值，然后进行测量事件A2判决，触发测量事件A2上报。
S605，终端设备根据修改后的服务小区的测量结果和邻小区的测量结果，进行测量事件A3或A5的判决。
进一步地，在S606中，进行测量事件A3或A5的上报。
从而网络设备可以根据终端设备的测量上报为终端设备选择合适的小区进行小区切换。
在S607中，终端设备可以接收网络设备的切换命令，进一步可以根据该切换命令进行小区切换。
可选地，所述切换命令可以包括切换至的目标小区的信息。
