Description

NR小区测量方法、终端设备及系统 技术领域
本申请涉及通信领域，尤其涉及新空口(new radio，NR)小区测量方法、终端设备及系统。
背景技术
在移动通信技术领域中，当终端设备需要接入到NR小区时，需要先对该NR小区进行测量。
目前，终端设备基于其所在小区所属的基站(以下简称为第一基站)下发的测量间隔(measurement gap,GAP)对待接入的NR小区进行测量。具体来说，NR小区所属的基站(以下简称第二基站)会向第一基站上报自身发送同步信号块(synchronization signal block，SSB)的位置、周期及时长，第一基站接收到上述信息后，为终端设备配置对应的GAP。如图1所示，SSB是周期性发送的信号，在每个发送周期内，SSB被限定在一个有限长的时间窗内。GAP是一段周期性、有限长的时间段，终端设备在GAP的每个有限长时间段(称为GAP窗)内检测其中是否包含第二基站发送的SSB，并在检测到SSB后，基于SSB对NR小区进行测量，进而根据测量结果判断NR小区是否适合接入。通常，周期性发送的SSB包含在对应的GAP窗内，如图2(a)所示。
然而，现有技术中，存在第一基站不配置GAP的场景。此种场景下，即无法对NR小区进行测量。
此外，在第一基站为终端设备配置了对应的GAP的场景下：一方面，虽然第二基站向第一基站上报了自身发送SSB的位置、周期及时长，但第一基站和第二基站的时间可能不同步，这可能导致第一基站为终端设备配置的GAP窗未能包含第二基站发送的SSB，如图2(b)所示。另一方面，若第二基站基于非授权频谱和终端设备进行通信，则为了避免信道访问的冲突(实现频谱共享)，第二基站在发送SSB之前需要先通过先听后说(listen before talk，LBT)机制确定信道可用后，才能基于非授权频谱在预定位置处发送SSB；否则，第二基站将会推迟SSB的发送，而这可能会使SSB出现在GAP窗之外，如图2(b)所示。然而，若GAP窗内不包含SSB，则终端设备即无法在GAP窗内检测到第二基站发送的SSB，进而也就无法对NR小区进行测量。
发明内容
本申请实施例提供的NR小区测量方法、终端设备及系统，能够提高NR小区测量的成功率。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，提供一种NR小区测量方法，该方法包括：终端设备确定在无线资源管理(radio resource management，RRM)测量窗内未检测到待测NR小区；终端设备以RRM测量窗为基准确定扩展RRM测量窗；其中，扩展RRM测量窗的测量窗长大于RRM测量窗的测量窗长，扩展RRM测量窗完全或部分包含RRM测量窗；终端设 备在扩展RRM测量窗内搜索来自待测NR小区所属接入网设备的SSB，并基于SSB对待测NR小区进行测量。由于该方案中，扩展RRM测量窗的测量窗长大于RRM测量窗的测量窗长，扩展RRM测量窗完全或部分包含RRM测量窗，因此通过扩展RRM测量窗能够测量终端设备在相邻两个RRM测量窗之间(该部分RRM测量窗未覆盖到)接收到的信号，提升搜索到待测NR小区所属接入网设备发送的SSB的概率，从而提高NR小区的测量成功率。避免了现有技术中，未配置GAP或者配置的GAP窗内不包含SSB所导致的无法对NR小区进行测量的问题。
在一种可能的设计中，在终端设备在扩展RRM测量窗内搜索来自待测NR小区所属接入网设备的SSB之前，该方法还包括：终端设备确定自身有空闲射频资源；终端设备在扩展RRM测量窗的开始位置处，将待测NR小区建立为辅小区，并为待测NR小区分配射频资源。其中，射频资源用于接收来自待测NR小区所属接入网设备的SSB。基于该方案，终端设备可将空闲的射频资源单独分配给待测NR小区，从而利用该射频资源接收SSB，对待测NR小区进行测量。
在一种可能的设计中，在终端设备在扩展RRM测量窗内搜索来自待测NR小区所属接入网设备的SSB之前，该方法还包括：终端设备确定自身无空闲射频资源；终端设备在扩展RRM窗的开始位置处，去激活已建立的辅小区以释放射频资源，并将待测NR小区建立为辅小区，将释放的射频资源分配给待测NR小区，其中，射频资源用于接收来自待测NR小区所属接入网设备的SSB。即，当终端设备当前所在小区所属接入网设备配置了多个载波以至于没有空闲的射频资源可分配给待测NR小区用于测量的场景下，基于该方案，能够为待测NR小区分配射频资源，进而使得终端设备利用该射频资源接收SSB，对待测NR小区进行测量。
在一种可能的设计中，在终端设备在扩展RRM测量窗内搜索来自待测NR小区所属接入网设备的SSB之后，该方法还包括：终端设备在扩展RRM窗的结束位置处，去激活待测NR小区，并恢复已建立的辅小区。基于该方案，在测量完待测NR小区后就立即去激活待测NR小区，并同时恢复之前为测量待测NR小区去激活的辅小区，能够减少对已建立辅小区业务的影响。
在一种可能的设计中，待测NR小区为多个，已建立的辅小区为多个。基于该方案，能够对多个待测NR小区同时进行测量，提升测量效率。
在一种可能的设计中，扩展RRM测量窗的开始位置与RRM测量窗的开始位置相同；或者，扩展RRM测量窗的开始位置在RRM测量窗的结束位置之前。基于该方案，扩展RRM测量窗能够完全或部分包含RRM测量窗，从而提升搜索到待测NR小区所属接入网设备发送的SSB的概率，提高NR小区的测量成功率。
在一种可能的设计中，RRM测量窗为测量间隔GAP窗或SSB测量定时配置(SSB measurement timing configuration，SMTC)窗。
在一种可能的设计中，RRM测量窗为SMTC窗，在终端设备确定在RRM测量窗内未检测到待测NR小区之前，该方法还包括：终端设备确定未接收到来自其所在小区所属接入网设备的GAP窗的配置信息；终端设备接收来自其所在小区所属接入网设备的SMTC信息。基于该方案，在未配置GAP的场景下，可通过SMTC窗对待测NR小区进行测量。
第二方面，提供了另一种NR小区测量方法，该方法包括：终端设备接收SMTC信息；终端设备根据SMTC信息，在SMTC窗内搜索来自待测NR小区所属接入网设备的SSB，并基于SSB对待测NR小区进行测量。其中，所述SMTC信息包括SMTC窗的测量窗长、测量周期以及偏移量；SMTC窗的测量窗长等于待测NR小区所属接入网设备发送同步信号块SSB的周期，或，SMTC窗的测量窗长大于5ms；其中，偏移量为SMTC窗的开始位置相对于SMTC窗所在测量周期的开始位置的偏移量。在该方案中，由于为终端设备配置了测量窗长等于待测NR小区所属接入网设备发送SSB的周期的SMTC窗，因此，SMTC窗内必然包含SSB，终端设备在SMTC窗内必然会搜索到待测NR小区所属接入网设备发送的SSB，从而终端设备可基于搜索到的SSB对待测NR小区进行测量；或者，由于为终端设备配置了测量窗长大于5ms的SMTC窗(大于现有SMTC窗的最大测量窗长)，因此，相比现有技术，终端设备在该SMTC窗内搜索到SSB的概率更高，进而测量到NR小区的概率也就更高。即，该方案能够提升终端设备检测到SSB的概率，进而提高NR小区测量的成功率，避免了现有技术中，未配置GAP或者配置的GAP窗内不包含SSB所导致的无法对NR小区进行测量的问题。
在一种可能的设计中，该方法还包括：若终端设备在SMTC窗内搜索到来自待测NR小区所属接入网设备的SSB，终端设备向其所在小区所属接入网设备发送SSB的位置信息，SSB的位置信息用于重新配置SMTC信息；终端设备接收重新配置的SMTC信息，重新配置的SMTC信息中的测量窗长小于SMTC信息中的测量窗长；终端设备根据重新配置的SMTC信息，在对应SMTC窗内搜索SSB，并基于SSB对待测NR小区进行测量。基于该方案，由于新配置的SMTC窗包含待测NR小区所属接入网设备发送的SSB并且测量窗长小于原SMTC窗的测量窗长，因此后续终端设备根据该新配置的SMTC窗对待测NR小区测量，能够减小终端设备的资源消耗，进而提高资源利用率。
第三方面，提供了又一种NR小区测量方法，该方法包括：终端设备接收SMTC信息，终端设备根据SMTC信息，在第一SMTC窗和第二SMTC窗内搜索待测NR小区发送的同步信号块SSB，并基于SSB对待测NR小区进行测量。其中，SMTC信息包括第一SMTC窗和第二SMTC窗的测量窗长、测量周期以及偏移量，且第一SMTC窗和第二SMTC窗的偏移量不同，第一SMTC窗的偏移量为第一SMTC窗的开始位置相对于第一SMTC窗所在测量周期的开始位置的偏移量，第二SMTC窗的偏移量为第二SMTC窗的开始位置相对于第二SMTC窗所在测量周期的开始位置的偏移量。该方案中，为终端设备配置了两个偏移量不同的SMTC窗，相比现有技术仅配置一个偏移量固定的SMTC窗，在两个偏移量不同的SMTC窗内搜索到SSB的概率更高，因而终端设备测量到NR小区的概率也就更高。即，该方案能够提升终端设备检测到SSB的概率，进而提高NR小区测量的成功率，避免了现有技术中，未配置GAP或者配置的GAP窗内不包含SSB所导致的无法对NR小区进行测量的问题。
在一种可能的设计中，第一SMTC窗的测量周期小于第二SMTC窗的测量周期；相应的，终端设备根据SMTC信息，在第一SMTC窗和第二SMTC窗内搜索SSB，包括：终端设备优先在第一SMTC窗内搜索SSB；若终端设备在第一SMTC窗内搜索到 SSB，则终端设备不在第二SMTC窗内搜索SSB；若终端设备在第一SMTC窗内未搜索到SSB，则终端设备在第二SMTC窗内搜索SSB。基于该方案，能够节省终端设备的资源消耗，提高终端设备的资源利用率。
在一种可能的设计中，该方法还包括：若终端设备在第一SMTC窗或第二SMTC内搜索到来自待测NR小区所属接入网设备的SSB，终端设备向其所在小区所属接入网设备发送SSB的位置信息，SSB的位置信息用于重新配置SMTC信息；终端设备接收重新配置的SMTC信息，重新配置的SMTC信息包括第三SMTC窗和第四SMTC窗的测量窗长、测量周期以及偏移量；第三SMTC窗的测量窗长小于第一SMTC窗的测量窗长，或，第四SMTC窗的测量窗长小于第二SMTC窗的测量窗长；终端设备根据重新配置的SMTC信息，在第三SMTC窗和第四SMTC窗内搜索SSB，并基于SSB对待测NR小区进行测量。基于该方案，由于重新配置的SMTC窗包含待测NR小区所属接入网设备发送的SSB并且测量窗长小于原SMTC窗的测量窗长，因此后续终端设备根据该重新配置的SMTC窗对待测NR小区测量，能够减小终端设备的资源消耗，进而提高资源利用率。
第四方面，提供了一种通信装置用于实现上述各种方法。该通信装置可以为上述第一方面、第二方面或第三方面中的终端设备，或者包含上述终端设备的装置。该通信装置包括实现上述方法相应的模块、单元、或手段(means)，该模块、单元、或means可以通过硬件实现，软件实现，或者通过硬件执行相应的软件实现。该硬件或软件包括一个或多个与上述功能相对应的模块或单元。

第六方面，提供了一种通信装置，包括：处理器；该处理器用于与存储器耦合，并读取存储器中的指令之后，根据该指令执行如上述任一方面所述的方法。该通信装置可以为上述第一方面、第二方面或第三方面中的终端设备，或者包含上述终端设备的装置。

如图3所示，为本申请实施例提供的一种通信系统30，该通信系统30包括终端设备301和第一接入网设备302，第一接入网设备302为待测NR小区所属的接入网设备。终端设备301和第一接入网设备302之间可以直接通信，也可以通过其他设备的转发进行通信，本申请实施例对此不作具体限定。
其中，终端设备301，用于确定在RRM测量窗内未检测到待测NR小区，进而以RRM测量窗为基准确定扩展RRM测量窗。其中，扩展RRM测量窗的测量窗长大于RRM测量窗的测量窗长，扩展RRM测量窗完全或部分包含RRM测量窗。第一接入网设备302，用于向终端设备301发送SSB。终端设备301，还用于在扩展RRM测量窗内搜索来自第一接入网设备302的SSB，并基于SSB对待测NR小区进行测量。其中，上述方案的具体实现将在后续方法实施例中详细阐述，在此不予赘述。
可选的，如图3所示，本申请实施例提供的通信系统30还可以包括第二接入网设备303。其中，第二接入网设备303，用于向终端设备301发送RRM测量窗的配置信息。其中，第二接入网设备303为终端设备301所在小区所属的接入网设备。
在本申请实施例中，当终端设备301确定在原来配置的RRM测量窗内未搜索到来自第一接入网设备的SSB后，终端设备301以RRM测量窗为基准，确定了测量窗长更长且能够完全或部分包含原来RRM测量窗的扩展RRM测量窗，进而终端设备301在扩展RRM测量窗内搜索来自第一接入网设备302的SSB。基于该方案，由于扩展RRM测量窗的测量窗长大于RRM测量窗的测量窗长，扩展RRM测量窗完全或部分包含RRM测量窗，因此通过扩展RRM测量窗能够测量终端设备在相邻两个RRM测量窗之间(该部分RRM测量窗未覆盖到)接收到的信号，提升搜索到第一接入网设备发送的SSB的概率，从而提高NR小区的测量成功率。避免了现有技术中，未配置GAP或者配置的GAP窗内不包含SSB所导致的无法对NR小区进行测量的问题。
或者，如图4所示，为本申请实施例提供的另一种通信系统40，该通信系统40包括终端设备401、第一接入网设备402和第二接入网设备403。其中，第一接入网设备402为待测NR小区所属的接入网设备，第二接入网设备403为终端设备301所在小区所属的接入网设备。终端设备401和第一接入网设备402或第二接入网设备403之间可以直接通信，也可以通过其他设备的转发进行通信，本申请实施例对此不作具体限定。
一种可能的实现方式中，第一接入网设备402，用于向终端设备401发送SSB。 第二接入网设备403，用于向终端设备401发送SMTC信息。其中，SMTC信息包括SMTC窗的测量窗长、测量周期以及偏移量，SMTC窗的测量窗长等于第一接入网设备402发送SSB的周期，或，SMTC窗的测量窗长大于5ms。终端设备401，用于接收来自第二接入网设备403的SMTC信息，并根据SMTC信息，在SMTC窗内搜索来自第一接入网设备402的SSB，并基于SSB对待测NR小区进行测量。其中，上述方案的具体实现将在后续方法实施例中详细阐述，在此不予赘述。
在本申请实施例中，由于第一接入网设备402为终端设备401配置了测量窗长等于第二接入网设备403发送SSB的周期的SMTC窗，因此，SMTC窗内必然包含第二接入网设备403发送的SSB，终端设备401在SMTC窗内必然会搜索到第二接入网设备403发送的SSB，从而终端设备401可基于搜索到的SSB对待测NR小区进行测量。或者，由于第一接入网设备402为终端设备401配置了测量窗长大于5ms的SMTC窗(大于现有SMTC窗的最大测量窗长)，因此，相比现有技术，终端设备401在该SMTC窗内搜索到SSB的概率更高，进而测量到NR小区的概率也就更高。即，本申请实施例能够提升终端设备401检测到SSB的概率，进而提高NR小区测量的成功率，避免了现有技术中，未配置GAP或者配置的GAP窗内不包含SSB所导致的无法对NR小区进行测量的问题。
另一种可能的实现方式中，第一接入网设备402，用于向终端设备401发送SSB。第二接入网设备403，用于向终端设备401发送SMTC信息。其中，SMTC信息包括第一SMTC窗和第二SMTC窗的测量窗长、测量周期以及偏移量，且第一SMTC窗和第二SMTC窗的偏移量不同，第一SMTC窗的偏移量为第一SMTC窗的开始位置相对于第一SMTC窗所在测量周期的开始位置的偏移量，第二SMTC窗的偏移量为第二SMTC窗的开始位置相对于第二SMTC窗所在测量周期的开始位置的偏移量。终端设备401，用于接收来自第二接入网设备403的SMTC信息，并根据SMTC信息，在第一SMTC窗和第二SMTC窗内搜索来自第一接入网设备402的SSB，并基于SSB对待测NR小区进行测量。其中，上述方案的具体实现将在后续方法实施例中详细阐述，在此不予赘述。
在本申请实施例中，由于第一接入网设备402为终端设备401配置了两个偏移量不同的SMTC窗，因此，相比现有技术仅配置一个偏移量固定的SMTC窗，本申请实施例在两个偏移量不同的SMTC窗内搜索到SSB的概率更高，因而终端设备401测量到NR小区的概率也就更高。即，本申请实施例能够提升终端设备401检测到SSB的概率，进而提高NR小区测量的成功率，避免了现有技术中，未配置GAP或者配置的GAP窗内不包含SSB所导致的无法对NR小区进行测量的问题。

以图3所示的通信系统应用于图5所示的部署方式为NSA架构的5G网络中，第一接入网设备为NR节点，第二接入网设备为eNB，RRM测量窗为GAP窗为例，如图8所示，为本申请实施例提供的一种NR小区测量方法，包括如下步骤：
S801、eNB向终端设备发送GAP窗的配置信息。终端设备接收来自eNB的GAP窗的配置信息。
S802、NR节点向终端设备发送SSB。终端设备接收来自NR节点的SSB。
S803、终端设备在GAP窗内搜索来自NR节点的SSB，并基于SSB对待测NR小区进行测量。
S804、终端设备确定在GAP窗内未搜索到来自NR节点的SSB，进而确定在GAP窗内未检测到待测NR小区。
其中，步骤S801-S804的相关实现可参考现有技术，在此不予赘述。
S805、终端设备以GAP窗为基准确定扩展GAP窗。
其中，扩展GAP窗也可以称之为扩展RRM测量窗或采数窗。扩展GAP窗的测量窗长大于GAP窗的测量窗长，扩展GAP窗完全或部分包含GAP窗。
本申请实施例以GAP窗为基准确定扩展GAP窗，由于扩展GAP窗完全或部分包含GAP窗，且扩展GAP窗的测量窗长大于GAP窗的测量窗长，因此通过扩展GAP窗能够测量终端设备在相邻两个GAP窗之间(该部分GAP窗未覆盖到)接收到的信号，因此基于扩展GAP窗，能够提升终端设备搜索到来自NR节点的SSB的概率，对待测NR小区进行成功测量的概率较高。
一种可能的实现方式中，如图9所示，扩展GAP窗的开始位置与GAP窗的开始位置相同。需要说明的是，由于扩展GAP窗的测量窗长大于GAP窗的测量窗长，因 此该种实现方式下，扩展GAP窗必然完全包含GAP窗。
或者，另一种可能的实现方式中，扩展GAP窗的开始位置在GAP窗的结束位置之前。示例性的，参见图10(a)至图10(c)，在该种实现方式下，扩展GAP窗和GAP窗可以有以下三种位置关系：(1)扩展GAP窗的开始位置在GAP窗的开始位置和结束位置之间，如图10(a)所示，此时扩展GAP窗部分包含GAP窗；(2)扩展GAP窗的开始位置在GAP窗的开始位置之前，且扩展GAP窗的结束位置在GAP窗的结束位置之后，如图10(b)所示，此时扩展GAP窗完全包含GAP窗；(3)扩展GAP窗的开始位置在GAP窗的开始位置之前，且扩展GAP窗的结束位置在GAP窗的开始位置和结束位置之间，如图10(c)所示，此时扩展GAP窗部分包含GAP窗。
可选的，一种可能的实现方式中，本申请实施例提供的NR小区测量方法还包括如下步骤S806a-S809a：
S806a、终端设备确定自身有空闲射频资源。
S807a、终端设备在扩展GAP窗的开始位置处，将待测NR小区建立为辅小区，并为待测NR小区分配射频资源。
其中，射频资源用于接收来自待测NR小区所属接入网设备(在本实施例中即NR节点)的SSB。
需要说明的是，本实施例中将待测NR小区建立为辅小区是指：将待测NR小区虚拟为辅小区，进而按照辅小区的方式接收数据。
S808a、终端设备在扩展GAP窗内搜索来自NR节点的SSB。
S809a、终端设备基于搜索到的SSB对待测NR小区进行测量。
或者，可选的，另一种可能的实现方式中，本申请实施例提供的NR小区测量方法还包括如下步骤S806b-S810b：
S806b、终端设备确定自身无空闲射频资源。
S807b、终端设备在扩展GAP窗的开始位置处，去激活已建立的辅小区以释放射频资源，并将待测NR小区建立为辅小区，将释放的射频资源分配给待测NR小区。
其中，射频资源用于接收来自待测NR小区所属接入网设备(在本实施例中即NR节点)的SSB。
一种可能的实现方式中，当待测NR小区为多个时，终端设备可以去激活多个已建立的辅小区。
S808b、终端设备在扩展GAP窗内搜索来自NR节点的SSB。
S809b、终端设备在扩展GAP窗的结束位置处，去激活待测NR小区，并恢复步骤S807b中去激活的辅小区。
一种可能的实现方式中，若步骤S807b中去激活的辅小区为多个，此处步骤S809b中终端设备恢复步骤S807b中去激活的全部辅小区。
基于上述步骤S806b-步骤S809b，当处于LTE多载波场景时，终端设备无空闲射频资源可用，此时先去激活一个LTE辅小区，释放一套设备资源给待测NR小区，至终端设备对待测NR小区的采数完成后，立即释放资源，并恢复LTE辅小区业务。
值得说明的是，现有技术中，待测小区和LTE主小区时分时复用同一套射频资源，小区的测量被限定在GAP窗内进行。在GAP窗内，eNB不向终端设备发送业务数据， 相应的，终端设备可以不接收业务数据，因此该段时间可用于除LTE主小区同频和辅小区副载波同频之外的其他小区的测量，同时不影响终端设备的业务。本申请实施例中，由于扩展GAP窗完全或部分包含GAP窗，在扩展GAP窗包含GAP窗的时段内eNB未向终端设备发送业务数据，因此能在一定程度上减小由于小区测量对终端设备业务的影响。
S810b、终端设备基于搜索到的SSB对待测NR小区进行测量。
本申请实施例中，当终端设备确定在eNB配置的GAP窗内未搜索到来自NR节点的SSB后，终端设备以GAP窗为基准，确定了测量窗长更长且能够完全或部分包含原来GAP窗的扩展GAP窗，进而终端设备在扩展GAP窗内搜索来自NR节点的SSB。由于扩展GAP窗的测量窗长大于GAP窗的测量窗长，扩展GAP窗完全或部分包含GAP窗，因此通过扩展GAP窗能够测量终端设备在相邻两个GAP窗之间(该部分GAP窗未覆盖到)接收到的信号，从而提升终端设备搜索到NR节点发送的SSB的概率，进而提高NR小区的测量成功率。避免了现有技术中，配置的GAP窗内不包含SSB所导致的无法对NR小区进行测量的问题。
其中，上述步骤S801至S809a或者上述步骤S801至S810b中的终端设备的动作可以由图7所示的通信装置70中的处理器701调用存储器703中存储的应用程序代码来执行，本实施例对此不作任何限制。
以图3所示的通信系统应用于图5所示的部署方式为NSA架构的5G网络中，第一接入网设备为NR节点，第二接入网设备为eNB，RRM测量窗为SMTC窗为例，如图11所示，为本申请实施例提供的另一种NR小区测量方法，包括如下步骤：
S1101、终端设备确定未接收到来自eNB的GAP窗的配置信息。
S1102、eNB向终端设备发送SMTC信息。终端设备接收来自eNB的SMTC信息。
其中，SMTC信息为SMTC窗的配置信息。
S1103、NR节点向终端设备发送SSB。终端设备接收来自NR节点的SSB。
S1104、终端设备在SMTC窗内搜索NR节点发送的SSB，并基于SSB对待测NR小区进行测量。
S1105、终端设备确定在SMTC窗内未搜索到NR节点发送的SSB，进而确定在SMTC窗内未检测到待测NR小区。
其中，步骤S1101-S1105的相关实现可参考现有技术，在此不予赘述。
S1106、终端设备以SMTC窗为基准确定扩展SMTC窗。
其中，扩展SMTC窗也可以称之为扩展RRM测量窗或采数窗。扩展SMTC窗的测量窗长大于SMTC窗的测量窗长，扩展SMTC窗完全或部分包含SMTC窗。
本申请实施例以SMTC窗为基准确定扩展SMTC窗，由于扩展SMTC窗完全或部分包含SMTC窗，且扩展SMTC窗的测量窗长大于SMTC窗的测量窗长，因此通过扩展SMTC窗能够测量终端设备在相邻两个SMTC窗之间(该部分SMTC窗未覆盖到)接收到的信号，因此基于扩展SMTC窗，能够提升终端设备搜索到NR节点发送的SSB的概率，对待测NR小区进行成功测量的概率较高。
一种可能的实现方式中，扩展SMTC窗的开始位置与SMTC窗的开始位置相同。需要说明的是，由于扩展SMTC窗的测量窗长大于SMTC窗的测量窗长，因此该种实 现方式下，扩展SMTC窗必然完全包含SMTC窗。
或者，另一种可能的实现方式中，扩展SMTC窗的开始位置在SMTC窗的结束位置之前。该种实现方式下，扩展SMTC窗完全或部分包含SMTC窗。其中，扩展SMTC窗和SMTC窗的位置关系与上一实施例中扩展GAP窗和GAP窗的位置关系类似，可参考上一实施例中的相关描述，此处不再赘述。
可选的，一种可能的实现方式中，本申请实施例提供的NR小区测量方法还包括如下步骤S1107a-S1110a：
S1107a、终端设备确定自身有空闲射频资源。
S1108a、终端设备在扩展SMTC窗的开始位置处，将待测NR小区建立为辅小区，并为待测NR小区分配射频资源。
其中，射频资源用于接收来自待测NR小区所属接入网设备(在本实施例中即NR节点)的SSB。
需要说明的是，本实施例中将待测NR小区建立为辅小区指的是：将待测NR小区虚拟为辅小区，进而按照辅小区的方式接收数据。
S1109a、终端设备在扩展SMTC窗内搜索来自NR节点的SSB。
S1110a、终端设备基于搜索到的SSB对待测NR小区进行测量。
或者，可选的，另一种可能的实现方式中，本申请实施例提供的NR小区测量方法还包括如下步骤S1107b-S1111b：
S1107b、终端设备确定自身无空闲射频资源。
S1108b、终端设备在扩展SMTC窗的开始位置处，去激活已建立的辅小区以释放射频资源，并将待测NR小区建立为辅小区，将释放的射频资源分配给待测NR小区。
其中，射频资源用于接收来自待测NR小区所属接入网设备(在本实施例中即NR节点)的SSB。
一种可能的实现方式中，当待测NR小区为多个时，终端设备可以去激活多个已建立的辅小区。
S1109b、终端设备在扩展SMTC窗内搜索来自NR节点的SSB。
S1110b、终端设备在扩展SMTC窗的结束位置处，去激活待测NR小区，并恢复步骤S1108b中去激活的辅小区。
一种可能的实现方式中，若步骤S1108b中去激活的辅小区为多个，此处步骤S1110b中终端设备恢复步骤S1108b中全部去激活的辅小区。
S1111b、终端设备基于搜索到的SSB对待测NR小区进行测量。
本申请实施例中，终端设备确定eNB未配置GAP窗后，接收eNB配置的SMTC信息，并基于SMTC信息在SMTC窗内搜索来自NR节点的SSB。当终端设备确定在SMTC窗内未搜索到来自NR节点的SSB后，以SMTC窗为基准，确定了测量窗长更长且能够完全或部分包含原来SMTC窗的扩展SMTC窗，进而终端设备在扩展SMTC窗内搜索来自NR节点的SSB。由于扩展SMTC窗的测量窗长大于SMTC窗的测量窗长，扩展SMTC窗完全或部分包含SMTC窗，因此通过扩展SMTC窗能够测量终端设备在相邻两个SMTC窗之间(该部分SMTC窗未覆盖到)接收到的信号，从而提升终端设备搜索到NR节点发送的SSB的概率，进而提高NR小区的测量成功率。避免了 现有技术中，未配置GAP窗所导致的无法对NR小区进行测量的问题。
其中，上述步骤S1101至S1110a或者上述步骤S1101至S1111b中的终端设备的动作可以由图7所示的通信装置70中的处理器701调用存储器703中存储的应用程序代码来执行，本实施例对此不作任何限制。
以图4所示的通信系统应用于图5所示的部署方式为NSA架构的5G网络中，第一接入网设备为NR节点，第二接入网设备为eNB为例，如图12所示，为本申请实施例提供的又一种NR小区测量方法，包括如下步骤：
S1201、eNB向终端设备发送SMTC信息。终端设备接收来自eNB的SMTC信息。
其中，SMTC信息即SMTC窗的配置信息，包括SMTC窗的测量窗长、测量周期以及偏移量。偏移量为SMTC窗的开始位置相对于SMTC窗所在测量周期的开始位置的偏移量。示例性的，如图13所示，图中SMTC窗所在测量周期的开始位置为无线帧0的起始位置，SMTC窗的开始位置为无线帧1的起始位置，即无线帧1的子帧0的开始位置，无线帧0的起始位置到无线帧1的起始位置之间有10个子帧，对应的时长为10ms，因此SMTC窗的偏移量为10ms。
一种可能的实现方式中，SMTC窗的测量窗长等于NR节点发送SSB的周期。其中，NR节点发送SSB的周期，也即SSB的传输周期，例如可能是5ms、10ms、20ms、40ms、80ms或者160ms等，本发明实施例对此不作具体限定。
可以理解，由于SSB每个发送周期内必然包含NR节点发送的SSB，因此将SMTC窗的测量窗长配置为SSB的传输周期后，每个SMTC窗内必然包含NR节点发送的SSB，终端设备在SMTC窗内必然会搜索到NR节点发送的SSB。
示例性的，假设eNB已知NR节点发送的SSB的发送周期为10ms，SSB的发送时长为5ms，则如图13所示，eNB可以为终端设备配置测量窗长为10ms、测量周期为40ms、偏移量为10ms的SMTC窗。这样一来，无论NR节点发送SSB的实际位置位于SSB发送周期10ms中的哪5个子帧(图13中以SSB位于子帧1-5为例进行示意)，每个SMTC窗内必然包含SSB，终端设备在SMTC窗内可以搜索到NR节点发送的SSB。
或者，另一种可能的实现方式中，SMTC窗的测量窗长大于5ms。示例性的，SMTC窗的测量窗长例如可以配置为10ms、20ms或者40ms，本发明实施例对此不作具体限定。
可以理解，由于现有的SMTC信息中，SMTC窗的测量窗长为1ms～5ms，即最长为5ms，因此将SMTC窗的测量窗长配置为大于5ms后，相比现有技术，本申请实施例在SMTC窗内搜索到SSB的概率更高。
S1202、NR节点向终端设备发送SSB。终端设备接收来自NR节点的SSB。
S1203、终端设备根据SMTC信息，在SMTC窗内搜索来自NR节点的SSB，并基于SSB对待测NR小区进行测量。
S1204、可选的，若终端设备在SMTC窗内搜索到来自NR节点的SSB，终端设备向NR节点发送SSB的位置信息。NR节点接收来自终端设备的SSB的位置信息。
其中，SSB的位置信息用于重新配置SMTC信息。
S1205、可选的，NR节点向终端设备发送重新配置的SMTC信息。终端设备接收来自NR节点的重新配置的SMTC信息。
其中，终端设备根据重新配置的SMTC信息可以确定NR节点为其新配置的SMTC窗。重新配置的SMTC信息中的测量窗长小于SMTC信息中的测量窗长。
一种优选的实现方式中，新配置的SMTC窗内包含NR节点发送的SSB，并且新配置的SMTC窗的测量窗长等于NR节点发送SSB的发送时长。即，使新配置的SMTC窗恰好包含NR节点发送的SSB，这样一来，既可确保在SMTC窗内搜索到SSB，又可最大程度的减少资源占用。
S1206、可选的，终端设备根据重新配置的SMTC信息，在对应SMTC窗内搜索SSB，并基于SSB对待测NR小区进行测量。
基于上述步骤S1204至S1206，NR节点根据SSB的位置信息为终端设备配置新的SMTC窗，由于新配置的SMTC窗包含NR节点发送的SSB并且测量窗长小于原SMTC窗的测量窗长，因此后续终端设备根据该新配置的SMTC窗对待测NR小区测量，能够减小终端设备的资源消耗，进而提高资源利用率。
在本申请实施例中，由于eNB为终端设备配置了测量窗长等于NR节点发送SSB的周期的SMTC窗，因此SMTC窗内必然包含NR节点发送的SSB，终端设备在SMTC窗内能够搜索到NR节点发送的SSB，基于搜索到的SSB即可对待测NR小区进行测量。或者，在本申请实施例中，由于eNB为终端设备配置了测量窗长大于5ms的SMTC窗(大于现有SMTC窗的最大测量窗长)，因此，相比现有技术，终端设备在该SMTC窗内搜索到SSB的概率更高，进而测量到NR小区的概率也就更高。即，本申请实施例能够提升终端设备检测到SSB的概率，进而提高NR小区测量的成功率，避免了现有技术中，未配置GAP或者配置的GAP窗内不包含SSB所导致的无法对NR小区进行测量的问题。
其中，上述步骤S1201至S1206中的终端设备的动作可以由图7所示的通信装置70中的处理器701调用存储器703中存储的应用程序代码来执行，本实施例对此不作任何限制。
以图4所示的通信系统应用于图5所示的部署方式为NSA架构的5G网络中，第一接入网设备为NR节点，第二接入网设备为eNB为例，如图14所示，为本申请实施例提供的又一种NR小区测量方法，包括如下步骤：
S1401、eNB向终端设备发送SMTC信息。终端设备接收来自eNB的SMTC信息。
其中，SMTC信息即SMTC窗的配置信息，包括第一SMTC窗和第二SMTC窗的测量窗长、测量周期以及偏移量，且第一SMTC窗和第二SMTC窗的偏移量不同。其中，第一SMTC窗的偏移量为第一SMTC窗的开始位置相对于第一SMTC窗所在测量周期的开始位置的偏移量，第二SMTC窗的偏移量为第二SMTC窗的开始位置相对于第二SMTC窗所在测量周期的开始位置的偏移量。
示例性的，假设eNB已知NR节点发送的SSB的发送周期为10ms，SSB的发送时长为5ms，则如图15所示，eNB可以为终端设备配置测量窗长为5ms，测量周期为40ms，偏移量分别为10ms和15ms的两个SMTC窗。假设SSB的发送位置是在子帧1至子帧5上发送，一个SMTC窗在无线帧1的10ms中，测量窗长为5ms，偏移量为10ms，则终端设备在该SMTC窗内搜索，可以获取到子帧1至子帧4上的SSB信息。另一SMTC窗在无线帧5的10ms中，测量窗长为5ms，偏移量为15ms，则终端设备 在该SMTC窗内搜索，可以获取到子帧5上的SSB信息。这样一来，终端设备就可以根据这两个不同偏移的SMTC窗，获取到完整的SSB信息，进而基于该SSB信息对待测NR小区进行测量。
可以理解，由于现有的SMTC窗的配置信息中，仅配置了一个偏移量固定的SMTC窗，而本申请实施例中配置了两个偏移量不同SMTC窗，因此相比现有技术，本申请实施例在两个偏移量不同的SMTC窗内搜索到SSB的概率更高。
S1402、NR节点向终端设备发送SSB。终端设备接收来自NR节点的SSB。
S1403、终端设备根据SMTC信息，在第一SMTC窗和第二SMTC内搜索来自NR节点的SSB，并基于SSB对待测NR小区进行测量。
一种优选的实现方式中，第一SMTC窗的测量周期小于第二SMTC窗的测量周期。
相应的，步骤S1403具体可以包括如下所示的步骤S1403′(图14中未示出)：
S1403′、终端设备优先在第一SMTC窗内搜索SSB：若终端设备在第一SMTC窗内搜索到SSB，则终端设备不在第二SMTC窗内搜索SSB；若终端设备在第一SMTC窗内未搜索到SSB，则终端设备在第二SMTC窗内搜索SSB。
示例性的，接上一示例，例如，可以将第一SMTC窗的测量周期配置为20ms，第二SMTC窗的测量周期配置为80ms，则终端设备优先在测量周期较短的第一SMTC窗内搜索SSB，如果搜索到NR节点发送的SSB，则不再在第二SMTC窗内搜索SSB；反之，如果终端设备在第一SMTC窗内未搜索到NR节点发送的SSB，则再第二SMTC窗内继续搜索SSB。
可以理解，该优选实现方式能够节省终端设备的资源消耗，进而提高资源利用率。
S1404、可选的，若终端设备在第一SMTC窗或第二SMTC内搜索到来自NR节点的SSB，终端设备向NR节点发送SSB的位置信息。NR节点接收来自终端设备的SSB的位置信息。
其中，SSB的位置信息用于重新配置SMTC信息。
S1405、可选的，NR节点向终端设备发送重新配置的SMTC信息。终端设备接收来自NR节点的重新配置的SMTC信息。
其中，终端设备根据重新配置的SMTC信息可以确定NR节点为其新配置的SMTC窗。
其中，一种可能的实现方式中，重新配置的SMTC信息包括第三SMTC窗和第四SMTC窗的测量窗长、测量周期以及偏移量。第三SMTC窗的测量窗长小于第一SMTC窗的测量窗长，或者，第四SMTC窗的测量窗长小于第二SMTC窗的测量窗长。
或者，一种优选的实现方式中，重新配置的SMTC信息仅包含一个SMTC窗的测量窗长、测量周期以及偏移量，该SMTC窗内包含NR节点发送的SSB，并且该SMTC窗的测量窗长等于NR节点发送SSB的发送时长。
S1406、可选的，终端设备根据重新配置的SMTC信息，在第三SMTC窗和第四SMTC窗内搜索SSB，并基于SSB对待测NR小区进行测量。
或者，一种优选的实现方式中，终端设备根据重新配置的SMTC信息，在对应的单个SMTC窗(包含NR节点发送的SSB)内搜索SSB，并基于SSB对待测NR小区进行测量。
基于上述步骤S1404-S1406，NR节点根据SSB的位置信息重新为终端设备配置SMTC窗，由于重新配置的SMTC窗包含NR节点发送的SSB并且测量窗长小于原SMTC窗的测量窗长，因此后续终端设备根据该重新配置的SMTC窗对待测NR小区测量，能够减小终端设备的资源消耗，进而提高资源利用率。
在本申请实施例中，由于eNB为终端设备配置了两个偏移量不同的SMTC窗，因此，相比现有技术仅配置一个偏移量固定的SMTC窗，本申请实施例在两个偏移量不同的SMTC窗内搜索到SSB的概率更高，因而终端设备测量到NR小区的概率也就更高。即，本申请实施例能够提升终端设备检测到SSB的概率，进而提高NR小区测量的成功率，避免了现有技术中，未配置GAP或者配置的GAP窗内不包含SSB所导致的无法对NR小区进行测量的问题。
其中，上述步骤S1401至S1406中的终端设备的动作可以由图7所示的通信装置70中的处理器701调用存储器703中存储的应用程序代码来执行，本实施例对此不作任何限制。
