图10是本申请实施例提供的另一种基站的结构示意图。
下面结合本申请实施例中的附图对本申请实施例进行描述。
请参见图2，图2是本申请实施例提供的一种信号测量系统的架构示意图，该信号测量系统包括终端和基站。终端可以是指提供到用户的语音和/或数据连接的设备，也可以被连接到诸如膝上型计算机或台式计算机等的计算设备，或者其可以是诸如个人数字助理(Personal Digital Assistant，PDA)等的独立设备。终端还可以称为系统、用户单元、用户站、移动站、移动台、远程站、接入点、远程终端、接入终端、用户终端、用户代理或用户装置。基站可以为接入点、节点B、演进型节点(Environment Bureau，eNB)或5G基站(Next generation base station，gNB)，指在空中接口上通过一个或多个扇区与无线终端进行通信的接入网络中的设备。通过将已接收的空中接口帧转换为IP分组，基站可以作为无线终端和接入网络的其余部分之间的路由器，接入网络可以包括因特网协议网络。基站还可以对空中接口的属性的管理进行协调。
请参见图3，图3是本申请实施例提供的一种信号测量方法的流程示意图，该方法包括但不限于如下步骤：
S301，基站向终端发送测量指示。其中，所述测量指示可以包括发送信号的信号带宽发生切换。其中，信号带宽是终端需要测量的信号带宽，或者参考信号的带宽。
S302，终端在执行信号测量时确定基站的发送信号的信号带宽是否发生切换。
具体实现中，终端可以根据所述测量指示中包含的发送信号的信号带宽发生切换的指示，确定基站的发送信号的信号带宽是否发生切换。或者，终端在接收到基站的发送信号之后，终端直接确定基站的发送信号的信号带宽是否发生切换。
S303，终端若确定所述发送信号的信号带宽发生切换，则按照预设规则或所述基站
的测量指示，对切换后的所述发送信号的信号带宽或帧结构进行测量。
可选的，若确定所述发送信号的信号带宽发生切换，所述终端可以调整所述终端的射频带宽；然后根据调整后所述射频带宽，对切换后的所述发送信号的信号带宽或帧结构进行测量。其中，射频带宽是终端能够接收基站的发送信号的能力。例如：LTE系统中的终端大多具备20MHz的射频带宽能力。
进一步可选的，所述终端可以获取调整时长；所述终端根据所述调整时长，调整所述终端的射频带宽。其中，在调整时长内终端自行调整射频带宽，在调整时长内终端可能无法与基站进行通信，调整时长的大小不能长于预先规定的调整时长。其中，调整时长Gap的长度和位置可以是网络配置的，也可以由UE自行确定但网络未知，也可以由UE确定后通知网络。其中，调整时长(Gap)是专门配置终端进行测量的时间段结构。在调整时长内，终端可以做测量而不用进行数据通信。例如，在3GPP TS36.133协议中关于Gap的定义。
如图4、图5或图6所示，左边为切换前的信号带宽，右边为切换后的信号带宽，中间为调整时间，终端需要经过调整时长Gap从测量切换前的信号切换到测量切换后的信号。
可选的，所述终端获取切换后的所述发送信号的子载波数量、子载波间隔或帧结构大小；所述终端根据所述子载波数量、所述子载波间隔或所述帧结构大小，确定测量切换后的所述发送信号的测量时间阈值。其中，测量时间阈值可以为终端接收到基站的测量指示到发送测量报告的时间长度，也可以为基站发送测量指示到终端发送测量报告的时间长度，但并不局限于此。
进一步可选的，若切换后的所述发送信号中的子载波数量、子载波间隔或帧结构大小减小，则所述测量时间阈值减小；或者，若切换后的所述发送信号中的子载波数量、子载波间隔或帧结构大小增大，则所述测量时间阈值增加，或者，若切换后的发送信号中的子载波间隔大小改变，但是测量带宽不变，则测量时间阈值不变。
如图4所示，左边为切换前的信号带宽，右边为切换后的信号带宽，切换前的信号带宽大于切换后的信号带宽，因此需要的测量时间阈值减小。又图5所示，左边为切换前的信号带宽，右边为切换后的信号带宽，切换前的信号带宽小于切换后的信号带宽，因此需要的测量时间阈值增加。
进一步的，若所述终端的射频带宽发生变化但所述发送信号的信号带宽或帧结构不变，则所述测量时间阈值不变。
如图6所示，左边为切换前的信号带宽和射频带宽，右边为切换后的信号带宽和射频带宽。虽然切换前的射频带宽大于切换后的射频带宽，但是切换前的信号带宽与切换后的信号带宽相同，所述测量时间阈值仍保持不变。
可选的，当发送信号的信号带宽或者帧结构大小发生切换后，终端需要对切换后的帧结构或者信号带宽进行至少一次测量。
进一步可选的，所述终端获取所述信号带宽的切换次数；所述终端根据所述信号带宽的切换次数，确定测量切换后的所述发送信号的测量时间阈值。其中，若所述信号带宽的切换次数越多，则需要的测量时间阈值越大；若所述信号带宽的切换次数越小，则需要的
测量时间阈值越少。
可选的，可以按照切换前的测量精度对切换后的所述发送信号的信号带宽或帧结构进行测量。
可选的，在确定测量时间阈值之后，若所述终端测量切换后的所述发送信号的信号带宽或帧结构的时长超过所述测量时间阈值，则停止对切换后的所述发送信号的信号带宽或帧结构进行测量；或者，若所述终端测量切换后的所述发送信号的信号带宽或帧结构的时长超过所述测量时间阈值，则向所述基站发送测量报告；或者，若所述终端测量切换后的所述发送信号的信号带宽或帧结构的时长超过所述测量时间阈值，向所述基站发送测量超时或测量失败的指示信息。
S304，终端向所述基站发送测量报告。
具体实现中，基站可以首先确定所述终端测量切换后的所述发送信号的信号带宽或帧结构的测量时间阈值，在接收到终端发送的测量报告之后，若所述终端测量切换后的所述发送信号的信号带宽或帧结构的时长超过所述测量时间阈值，则停止接收所述终端发送的测量报告。或者，若所述终端测量切换后的所述发送信号的信号带宽或帧结构的时长超过所述测量时间阈值，则确定终端测量信号失败。若所述终端测量切换后的所述发送信号的信号带宽或帧结构的时长未超过所述测量时间阈值，则确定终端信号测量成功。
可选的，所述停止接收所述终端发送的测量报告之后，所述基站可以向所述终端发送询问消息，所询问消息用于指示所述终端返回所述终端当前状态。终端接收到询问消息之后，将终端当前状态返回给基站。
上述详细阐述了本申请实施例的方法，下面提供了本申请实施例的装置。
