Description

小区测量的方法与装置 技术领域
本申请涉及通信领域，并具体地，涉及一种小区测量的方法与装置。
背景技术
5G系统采用毫米波进行通信，而毫米波存在传输距离短，穿透和绕射能力差，容易受到气候环境影响等缺点，因此通过波束赋形(beam forming，BF)技术克服上述不足。然而BF技术的引入，会导致5G系统相比LTE系统存在众多的测量对象和复杂的测量场景。如何降低UE的处理复杂度，提高测量的效率，成为终端亟待解决的问题。
发明内容
本申请提供一种小区测量的方法与装置，可以有效提高小区测量的效率。
第一方面，一种小区测量的方法，例如，该方法由终端设备执行。该方法包括：获取辅助信息，该辅助信息包括服务小区与邻小区之间的定时偏差；根据该辅助信息以及该服务小区的同步信号块索引(synchronization signal block index，SSB ID)，获取该邻小区的同步信号块索引(SSB ID)。
现有技术中，终端设备通常通过解析邻小区的广播信道(physical broadcast channel，PBCH)来获取邻小区的SSB ID。而本申请基于服务小区与邻小区之间的定时偏差以及服务小区的SSB ID，来获取邻小区的SSB ID，相比于现有技术，可以避免解析邻小区的广播信道，从而可以提高小区测量的效率。
结合第一方面，在第一方面的一种可能的实现方式中，该定时偏差表示该邻小区与该服务小区同步，其中，该邻小区的同步信号块索引与该服务小区的同步信号块索引相同。
当服务小区与邻小区之间的定时偏差在预设偏差范围内时，表示邻小区与服务小区同步。该预设偏差范围可以根据实际需求设定。例如，设定预设偏差范围为35.21us，则当服务小区与邻小区之间的定时偏差小于或等于35.21us时，表示邻小区与服务小区同步。
结合第一方面，在第一方面的一种可能的实现方式中，该定时偏差表示该邻小区与该服务小区不同步，该辅助信息还包括该邻小区的子载波间隔；该获取该邻小区的同步信号块索引，包括：根据该定时偏差、该服务小区的同步信号块索引以及该邻小区的子载波间隔，获取该邻小区的同步信号块索引。
当服务小区与邻小区之间的定时偏差超出预设偏差范围时，表示邻小区与服务小区不同步。该预设偏差范围可以根据实际需求设定。例如，设定预设偏差范围为35.21us，则当服务小区与邻小区之间的定时偏差大于35.21us时，表示邻小区与服务小区不同步。
结合第一方面，在第一方面的一种可能的实现方式中，在服务小区与邻小区不同步的情况下，该邻小区的同步信号块索引的值为Currentneighbor_index，且
Currentneighbor_index＝(Currentserving_index+M-Delta)Mod M
M＝10*(SCS/15)，
其中，Currentserving_index表示该服务小区的同步信号块索引，SCS表示该邻小区的子载波间隔，Delta表示与定时偏差相关的参数。例如，Delta表示半帧的时间窗内整数个半时隙。
可选地，作为一种实现方式，根据该定时偏差、该服务小区的同步信号块索引以及该邻小区的子载波间隔，获取该邻小区的同步信号块索引，包括：根据如下公式，计算该邻小区的同步信号块索引Currentneighbor_index：
Currentneighbor_index＝(Currentserving_index+M-Delta)Mod M
M＝10*(SCS/15)，
其中，Currentserving_index表示该服务小区的同步信号块索引，SCS表示该邻小区的子载波间隔，Delta表示半帧的时间窗内整数个半时隙。
可选地，还可以通过其他方式来计算邻小区的同步信号块索引，本申请对此不做限定，只要基于服务小区与邻小区之间的定时偏差、该服务小区的同步信号块索引以及该邻小区的子载波间隔，获取该邻小区的同步信号块索引即可。
结合第一方面，在第一方面的一种可能的实现方式中，Delta＝Floor(((Tdiff+Ressymb_diff)Mod T_0.5frame)/T_0.5slot)，
其中，Tdiff表示该服务小区与该邻小区之间的定时偏差，T_0.5frame表示半帧的长度，T_0.5slot表示半时隙的长度，Floor()表示向下取整。如果该服务小区与该邻小区之间的定时偏差为该服务小区与该邻小区之间帧头的定时偏差，则Ressymb_diff＝0；如果该服务小区与该邻小区之间的定时偏差为该服务小区的同步信号块索引为零与该邻小区的同步信号块索引为零之间的定时偏差，则Ressymb_diff＝Ressymb_serving-Ressymb_neighbor，其中，Ressymb_serving为该服务小区在同步信号块索引为零时的第一个符号与帧头之间预留的符号，Ressymb_neighbor为该邻小区在同步信号块索引为零时的第一个符号与帧头之间预留的符号。
在本申请中，针对邻小区与该服务小区之间同步或者不同步，相应采用不同的方式来获取邻小区的同步信号块索引，这样可以提高小区测量的效率。进一步地，在邻小区与该服务小区之间不同步的情况下，根据邻小区与该服务小区之间定时偏差的不同类型，相应采用不同的方式来获取邻小区的同步信号块索引，可以更进一步地提高小区测量的效率。
结合第一方面，在第一方面的一种可能的实现方式中，该邻小区的频点所在的频带对应两种子载波间隔；则该邻小区的子载波间隔为这两种子载波间隔中的一种。
从这两种子载波间隔中选择一种作为邻小区的子载波间隔的实现方式有多种。

可选地，作为再一种实现方式，根据所处的地理位置，从该两种子载波间隔中选择一种作为该邻小区的子载波间隔。
本申请在邻小区存在两种子载波间隔的情况下，通过从两种子载波间隔中选择一种作 为邻小区的子载波间隔，从而可以避免对邻小区进行两次小区搜索或者两次小区测量。
结合第一方面，在第一方面的一种可能的实现方式中，该获取该服务小区与该邻小区之间的定时偏差，包括：根据网络设备的配置，获取该服务小区与该邻小区之间的定时偏差。

结合第一方面，在第一方面的一种可能的实现方式中，该获取该服务小区与该邻小区之间的定时偏差，包括：通过对该邻小区进行小区搜索和/或定时跟踪，获得该服务小区与该邻小区之间的定时偏差。
因此，本申请提供的方案不限制于网络设备是否为终端设备配置辅助信息。如果网络设备为终端设备提供了辅助信息，则终端设备直接利用该辅助信息获取邻小区的SSB ID。如果网络设备为终端设备提供了辅助信息，但是，该辅助信息不足够，则终端设备自主获得未配置的辅助信息，例如，网络设备只配置了服务小区与邻小区之间的定时偏差，未配置邻小区的SCS，则终端设备自主获得邻小区的SCS；再例如，网络设备只配置了邻小区的SCS，未配置服务小区与邻小区之间的定时偏差，则终端设备自主获得服务小区与邻小区之间的定时偏差。如果网络设备完全没有配置上述辅助信息，终端设备可以自主获得上述辅助信息。
结合第一方面，在第一方面的一种可能的实现方式中，该辅助信息中还包括该邻小区的比特位图bitmap，该邻小区的bitmap表示该邻小区在单测量定时配置SMTC内传输同步信号块的时域位置。该方法还包括：根据所获取的该邻小区的同步信号块索引，以及该邻小区的bitmap，对该邻小区在该STMC内的其它同步信号块进行测量。
可选地，该邻小区的bitmap表示该邻小区在SMTC内传输同步信号块的实际时域位置。
本申请通过邻小区的一个SSB ID和邻小区的bitmap，获得邻小区在SMTC内的所有SSB ID，可以有效提高小区测量的效率，此外，可以降低终端设备的处理复杂度，从而降低终端设备的能耗。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于第五代(5th generation，5G)系统或新无线(new radio，NR)等。
本申请实施例中的终端设备可以指5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
图1为本申请实施例的场景示意图。本申请实施例的场景涉及网络设备和终端设备。网络设备具体为基站，如图1所示。终端设备位于服务小区与邻小区信号覆盖的重叠区域。终端设备通过小区搜索与测量，实现从服务小区重选或者切换到邻小区。其中在小区测量过程中，终端设备除了识别小区标识(cell ID)、频点、同步信号能量之外，还需要识别同步信号块索引(SSB ID)，即网络设备(例如基站)的发送波束索引(beam ID)。
图2为本申请实施例提供的方法的示意性流程图。该方法的执行主体为终端设备。该方法包括如下步骤。
S210，获取辅助信息，该辅助信息包括服务小区与邻小区之间的定时偏差。
服务小区表示终端设备当前所驻留的小区。邻小区表示终端设备待测量的相邻小区。例如，服务小区与邻小区相邻，终端设备位于服务小区与邻小区信号覆盖的重叠区域。
当服务小区与邻小区之间的定时偏差在预设偏差范围内时，表示邻小区与服务小区同步。该预设偏差范围可以根据实际需求设定。例如，设定预设偏差范围为35.21us，则当服务小区与邻小区之间的定时偏差小于或等于35.21us时，表示邻小区与服务小区同步。
当服务小区与邻小区之间的定时偏差超出预设偏差范围时，表示邻小区与服务小区不同步。该预设偏差范围可以根据实际需求设定。例如，设定预设偏差范围为35.21us，则当服务小区与邻小区之间的定时偏差大于35.21us时，表示邻小区与服务小区不同步。
本文中涉及的邻小区与服务小区同步指的是邻小区与服务小区时间同步，邻小区与服务小区不同步指的是邻小区与服务小区时间不同步。
服务小区与邻小区之间的定时偏差也可称为邻小区与服务小区的同步信息指示。
S220，根据该辅助信息以及该服务小区的同步信号块索引(synchronization signal block index，SSB ID)，获取该邻小区的同步信号块索引(SSB ID)。
应理解，终端设备当前驻留在服务小区，因此，可以获得服务小区的SSB ID。
现有技术中，终端设备通常通过解析邻小区的广播信道(physical broadcast channel，PBCH)来获取邻小区的SSB ID。而本申请实施例基于服务小区与邻小区之间的定时偏差以及服务小区的SSB ID，来获取邻小区的SSB ID，相比于现有技术，可以避免解析邻小区的广播信道，从而可以提高小区测量的效率。
可选地，在一些实施例中，该定时偏差表示该邻小区与该服务小区同步，其中，该邻小区的SSB ID与该服务小区的SSB ID相同。
当服务小区与邻小区之间的定时偏差在预设偏差范围内时，表示邻小区与服务小区同步。该预设偏差范围可以根据实际需求设定。例如，设定预设偏差范围为35.21us，则当服务小区与邻小区之间的定时偏差小于或等于35.21us时，表示邻小区与服务小区同步。
可选地，在一些实施例中，该定时偏差表示该邻小区与该服务小区不同步。
当服务小区与邻小区之间的定时偏差超出预设偏差范围时，表示邻小区与服务小区不同步。该预设偏差范围可以根据实际需求设定。例如，设定预设偏差范围为35.21us，则当服务小区与邻小区之间的定时偏差大于35.21us时，表示邻小区与服务小区不同步。
在该定时偏差表示该邻小区与该服务小区不同步的情况下，该辅助信息还包括该邻小区的子载波间隔(subcarrier spacing，SCS)。S220包括：根据服务小区与邻小区之间的定时偏差、邻小区的SCS、以及服务小区的SSB ID，获取邻小区的SSB ID。
作为一个示例，在服务小区与邻小区不同步的情况下，邻小区的同步信号块索引的值为Currentneighbor_index，且
Currentneighbor_index＝(Currentserving_index+M-Delta)Mod M
M＝10*(SCS/15)                     公式(1)，
其中，Currentserving_index表示该服务小区的同步信号块索引，SCS表示该邻小区的子载波间隔，Delta表示与定时偏差相关的参数。例如，Delta表示半帧的时间窗内整数个半时隙。
例如，邻小区的SCS的取值集合为{15，30，120，240}(单位：KHz)。
可选地，作为一种实现方式，根据上述公式(1)计算该邻小区的同步信号块索引Currentneighbor_index。
可选地，服务小区与邻小区之间的定时偏差可以有多种类型。例如，服务小区与邻小区之间的定时偏差为该邻小区与该服务小区之间帧头的定时偏差。再例如，服务小区与邻小区之间的定时偏差为该服务小区的SSB ID等于零与该邻小区的SSB ID等于零之间的定时偏差。
公式(1)中的Delta的值在不同类型的定时偏差的情况下，取值不同。
作为一个示例，公式(1)中的Delta根据如下公式确定：
Delta＝Floor(((Tdiff+Ressymb_diff)Mod T_0.5frame)/T_0.5slot)         公式(2)，
其中，Tdiff表示该服务小区与该邻小区之间的定时偏差，T_0.5frame表示半帧的长度，T_0.5slot表示半个时隙的长度，Floor()表示向下取整。
当该服务小区与该邻小区之间的定时偏差为该邻小区与该服务小区之间帧头的定时偏差，则Ressymb_diff＝0，即Delta＝Floor((Tdiff Mod T_0.5frame)/T_0.5slot)。
当该服务小区与该邻小区之间的定时偏差为该服务小区的SSB ID等于零与该邻小区的SSB ID等于零之间的定时偏差，则Ressymb_diff＝Ressymb_serving-Ressymb_neighbor，其中，Ressymb_serving为该服务小区在SSB ID＝0时的第一个符号与帧头之间预留的符号(symbol)数，Ressymb_neighbor为该邻小区在SSB ID＝0时的第一个符号与帧头之间预留的符号数。即
Delta＝Floor(((Tdiff+Ressymb_serving-Ressymb_neighbor)Mod T_0.5frame)/T_0.5slot)。
例如，本文提及的符号数为OFDM符号数。
作为示例。SCS为15KHz时预留2个OFDM符号。SCS为30KHz时，对于普通频带预留2个OFDM符号，对于特殊频带(例如，上行共享(UL sharing)特殊频带)预留4个OFDM符号。SCS为120KHz时预留4个OFDM符号，SCS为240KHz时预留8个OFDM符号。
应理解，上文描述的服务小区与邻小区之间的定时偏差的类型仅为示例而非限定，实际应用中，还可以定义其它类型的定时偏差，如果定义了其它类型的定时偏差，相对应地，修改计算邻小区的SSB ID的计算方法。
还应理解，上文描述的公式(1)和公式(2)仅为示例而非限定。在服务小区与邻小区不同步的情况下，只要是根据服务小区与邻小区之间的定时偏差、邻小区的SCS、以及服务小区的SSB ID，获取邻小区的SSB ID的方案均落入本申请的保护范围。
可选地，在邻小区与服务小区不同步的情况下，网络设备向终端设备发送服务小区与邻小区之间定时偏差，例如该定时偏差为服务小区与邻小区之间帧头的定时偏差，或服务小区的SSB ID为零与邻小区的SSB ID为零之间的定时偏差，或服务小区与邻小区之间符号级的偏差。
相对于现有技术，本实施例在获取邻小区的SSB ID时，区分处理的程度从邻小区和服务小区之间是否同步，扩展到邻小区和服务小区之间包括无线帧在内的定时偏差、或包括系统帧号(system frame number，SFN)在内的定时偏差、或包括符号级在内的定时偏差。
在本申请实施例中，针对邻小区与该服务小区之间同步或者不同步，相应采用不同的方式来获取邻小区的同步信号块索引，这样可以提高小区测量的效率。进一步地，在邻小区与该服务小区之间不同步的情况下，根据邻小区与该服务小区之间定时偏差的不同类型，相应采用不同的方式来获取邻小区的同步信号块索引，可以更进一步地提高小区测量的效率。
在本申请中，终端设备获取辅助信息的实现方式可以有多种。
具体地，终端设备获取服务小区与邻小区的定时偏差的方式有多种。
可选地，在S210中，获取该服务小区与该邻小区之间的定时偏差，包括：根据网络设备的配置，获取该服务小区与该邻小区之间的定时偏差。
具体地，网络设备向终端设备配置辅助信息，该辅助信息中携带该服务小区与该邻小区之间的定时偏差。
例如，网络设备通过无线资源控制(radio resource control，RRC)信令配置所述服务小区与所述邻小区之间的定时偏差。
可选地，网络设备不为终端设备配置服务小区与邻小区之间的定时偏差，在S210中，获取该服务小区与该邻小区之间的定时偏差，包括：通过对该邻小区进行小区搜索和/或定时跟踪，获得该服务小区与该邻小区之间的定时偏差。
具体地，通过对所述邻小区进行小区搜索和/或定时跟踪，获得所述邻小区的定时，进而获得所述服务小区与所述邻小区之间的定时偏差。
终端设备获取邻小区的子载波间隔SCS的方式有多种。
可选地，在一些实施例中，终端设备根据网络设备的配置确定邻小区的SCS。
例如，网络设备为终端设备配置SCS，终端设备利用网络设备配置的SCS作为邻小区的SCS。
可选地，在一些实施例中，网络设备不为终端设备配置邻小区的SCS，这种情形下，终端设备可以先确定频点所在频段，然后根据如表1所示的频段与SCS之间的对应关系，确定频段对应的SCS，进而获得邻小区的SCS。
表1
Figure PCTCN2018094836-appb-000001
Figure PCTCN2018094836-appb-000002
假设，频点所在的频段为表1中所示的频段n7，则终端设备获知邻小区的SCS为15kHz。
此外，从表1还可知，如果频点位于普通频段(表1中除n5，n66，n257，n260以外的频段)，SSB对应一种SCS；如果频点位于混合频段(如表1中所示的n5，n66，n257，n260)，SSB对应两种SCS。
应理解，频点所在的频带是否包括一种或两种SCS，与运营商的频谱部署或者地域有关。
可选地，本文中提及的频点指的是邻小区的频点。
可选地，在终端设备初始接入场景中，本文中提及频点也可以是服务小区的频点。
现有技术中，针对表1中所示的混合频段中，SSB对应的两种SCS，终端设备盲检SCS，即通过尝试两次小区搜索或者小区测量确定一种SCS。
在本申请中，为了避免对邻小区进行两次小区搜索或者两次小区测量，提出如下解决方式。
可选地，在一些实施例中，该邻小区的频点所在的频带对应两种子载波间隔；该方法还包括：从该两种子载波间隔中选择一种作为该邻小区的子载波间隔。
从两种子载波间隔中选择一种作为邻小区的子载波间隔的实现方式有多种。
可选地，作为一种实现方式，根据网络设备的配置，从两种子载波间隔中选择一种子载波间隔作为邻小区的子载波间隔。
可选地，作为另一种实现方式，排除两种子载波间隔中的一种子载波间隔，将剩余的另一种子载波间隔作为邻小区的子载波间隔，其中，被排除的子载波间隔对应的同步信号块索引大于频点所在的频带的最大的同步信号块索引。
例如，邻小区的频点所在的频带对应两种子载波间隔，15KHz与30KHz，且子载波间隔为15KHz对应的同步信号块索引为7，子载波间隔为30KHz对应的同步信号块索引为14，假设该频点所在频带的最大的同步信号块索引为8，则排除子载波间隔30KHz，选择子载波间隔15KHz作为邻小区的子载波间隔。
再例如，邻小区的频点所在的频带对应两种子载波间隔，120KHz与240KHz，且子载波间隔为120KHz对应的同步信号块索引为60，子载波间隔为240KHz对应的同步信号块索引为120，假设该频点所在频带的最大的同步信号块索引为64，则排除子载波间隔 240KHz，选择子载波间隔120KHz作为邻小区的子载波间隔。
当邻小区的频点所在的频带对应的两种子载波间隔对应的同步信号块索引均小于该频点所在的频带的最大的同步信号块索引时，可以采用其它方式从这两种子载波间隔中选择一种作为邻小区的子载波间隔。例如，通过对邻小区进行小区搜索或解析邻小区的PBCH，从这两种子载波间隔中选择一种作为邻小区的子载波间隔。
可选地，作为再一种实现方式，根据终端设备所处的地理位置，从该两种子载波间隔中选择一种作为该邻小区的子载波间隔。
例如运营商1在位置1部署SCS1，运营商2在位置2部署SCS2，就可以通过位置1和位置2区分两种SCS，从而从两种SCS中选择一种作为邻小区的子载波间隔。
本申请实施例，在邻小区存在两种SCS的情况下，通过从两种子载波间隔中选择一种作为邻小区的子载波间隔，从而可以避免对邻小区进行两次小区搜索或者两次小区测量。
可选地，在上述某些实施例中，S210包括：终端设备接收网络设备发送的辅助信息，该辅助信息中携带服务小区与邻小区之间的定时偏差，以及邻小区的SCS。
上文已述，可选地，在网络设备未配置服务小区与邻小区之间的定时偏差的情况下，终端设备可以自主获得服务小区与邻小区之间的定时偏差，具体方法参见上文描述。在网络设备未配置邻小区的子载波间隔的情况下，终端设备可以自主获得邻小区的子载波间隔，具体方法参见上文描述。
因此，本申请实施例的方案不限制于网络设备是否为终端设备配置辅助信息。如果网络设备为终端设备提供了辅助信息，则终端设备直接利用该辅助信息获取邻小区的SSB ID。如果网络设备为终端设备提供了辅助信息，但是，该辅助信息不足够，则终端设备自主获得未配置的辅助信息，例如，网络设备只配置了服务小区与邻小区之间的定时偏差，未配置邻小区的SCS，则终端设备自主获得邻小区的SCS；再例如，网络设备只配置了邻小区的SCS，未配置服务小区与邻小区之间的定时偏差，则终端设备自主获得服务小区与邻小区之间的定时偏差。如果网络设备完全没有配置上述辅助信息，终端设备可以自主获得上述辅助信息。
换言之，本申请实施例提供的方案可以适用于网络设备向终端设备提供辅助信息的场景，也可以适用于网络设备不向终端设备提供辅助信息的场景，即本申请实施例提供的方案具有较为广泛的适用范围。
通常在一个单测量定时配置(single measurement timing configuration，SMTC)内，网络设备会传输多个SSB，且在一个SMTC内，有些时域位置上有SSB，有些时域位置上没有SSB。因此，在测量邻小区的SSB之前，需要先确定在一个SMTC内SSB的时域位置。
现有技术中，会逐个推算一个SMTC内的所有SSB的时域位置，处理耗时较大，处理效率较低。
针对上述弊端，本申请实施例提出通过邻小区的比特位图(bitmap)来获取SMTC内的SSB ID，可以有效提高小区测量的效率。
本文提及的bitmap指的是小区或者测量频点对应的bitmap。
可选地，在上述某些实施例中，S210中获取的辅助信息中还包括该邻小区的比特位 图(bitmap)，该邻小区的bitmap表示该邻小区在SMTC内传输同步信号块的时域位置；该方法200还包括：根据所获取的该邻小区的同步信号块索引，以及该邻小区的bitmap，对该邻小区在该STMC内的其它同步信号块进行测量。
可选地，所述邻小区的bitmap表示所述邻小区在SMTC内传输同步信号块的实际时域位置。
终端设备获取邻小区的bitmap的实现方式有多种。
可选地，作为一种实现方式，获取该邻小区的bitmap，包括：根据网络设备的配置，获取该邻小区的bitmap。
这种情况下，终端设备可以根据网络设备的配置，直接获取邻小区在SMTC内实际传输的SSB的bitmap。
例如，网络设备通过RRC信令给终端配置邻小区的SMTC以及SMTC bitmap，SMTC bitmap指示邻小区在SMTC内实际传输的SSB。例如，bitmap的长度L为64比特。
可选地，网络设备配置的SMTC包括：测量窗口周期(measurement window periodicity)、持续时间(duration)和偏移(offset)等参数，这些参数用于规定终端设备在该SMTC内进行SSB的测量。
终端设备将网络设备配置的SMTC bitmap作为用于确定邻小区在SMTC内的所有SSB ID的bitmap。
可选地，作为另一种实现方式，该邻小区为历史服务小区；该方法200还包括：存储该历史服务小区的bitmap；其中，该获取该邻小区的bitmap，包括：将该历史服务小区的bitmap作为该邻小区的bitmap。
例如，终端设备历史驻留在小区1(即历史服务小区)，驻留小区1时，网络设备配置了小区1的bitmap，终端设备存储小区1的bitmap。之后，终端设备由小区1切换到小区2，驻留小区2时，网络设备配置了小区2的bitmap，终端设备存储小区2的bitmap。在小区2驻留之后，终端设备再次预备切换到小区1，对于此时的终端设备来说，小区1为待测量的邻小区，由于之前存储了小区1的bitmap，因此，终端设备可以将之前存储的小区1的bitmap作为当前邻小区的bitmap。应理解，如果之后小区2也变成待测量的邻小区，终端设备也可以根据预先存储的小区2的bitmap，获得当前邻小区的bitmap。
可选地，作为再一种实现方式，该邻小区为历史邻小区；该方法200还包括：存储该历史邻小区的bitmap；其中，该获取该邻小区的bitmap，包括：将该历史邻小区的bitmap作为该邻小区的bitmap。
例如，终端设备历史驻留在小区1(即历史服务小区)，邻小区(即历史邻小区)为小区3，驻留小区1时，网络设备不仅配置了小区1的bitmap，还是配置了小区3的bitmap，终端设备存储小区1和小区3的bitmap。之后，终端设备由小区1切换到小区2。在小区2驻留之后，终端设备预备切换到小区3，对于此时的终端设备来说，小区3为待测量的邻小区(即当前邻小区)，由于之前存储了小区3的bitmap，因此，终端设备可以将之前存储的小区3的bitmap作为当前邻小区的bitmap。
需要说明的是，在小区测量时，如果网络设备配置了当前邻小区的bitmap，即使终端设备预先存储了该邻小区(作为历史服务小区或历史邻小区)的bitmap，当前邻小区的bitmap还是以网络设备的配置为准。
可选地，在一些实施例中，该邻小区为历史服务小区或历史邻小区；该方法200还包括：存储该历史服务小区或该历史邻小区的bitmap；接收网络设备配置的该邻小区的bitmap。获取该邻小区的bitmap，包括：当该历史服务小区或该历史邻小区的bitmap与该网络设备配置的bitmap不一致时，将该网络设备配置的bitmap作为该邻小区的bitmap。
本申请实施例通过邻小区的一个SSB ID和邻小区的bitmap，获得邻小区在SMTC内的所有SSB ID，可以有效提高小区测量的效率，此外，可以降低终端设备的处理复杂度，从而降低终端设备的能耗。
例如，终端设备根据某一个SSB ID推算获得SMTC内所有的SSB ID。换言之，本申请的方案约束一个SMTC内最多解一次PBCH，或者根据服务区的定时和同步信息指示，最多推算一次邻区的SSB ID，避免SMTC内的每个SSB都去解PBCH或者逐个推算邻区的SSB ID。
上述可知，终端设备获取用于确定邻小区在SMTC内的所有SSB ID的bitmap的方式，可以是通过网络设备配置来实现，也可以通过存储历史小区(历史服务小区或历史邻小区)的bitmap来实现。
可选地，在上述某些实施例中，该方法还包括：设定信号功率门限；当当前测量的同步信号块的信号功率小于所述信号功率门限时，降低所述当前测量的同步信号块附近的同步信号块的测量优先级，以便于提高下次测量的同步信号块的信号功率大于或等于所述信号功率门限的概率。
具体地，终端设备设定信号功率门限，当当前SSB的信号能量低于该信号功率门限时，认为当前SSB的信号能量较差，也认为当前SSB附近的SSB的信号能量也较差，则降低当前SSB附近的其他SSB的测量优先级，以便于提高下次测量的同步信号块的信号功率大于或等于所述信号功率门限的概率。
本申请通过设置信号功率门限，降低信号功率较低的同步信号块的测量优先级，从而可以优先测量信号功率较高的同步信号块，可以提高小区测量的效率。
基于上述描述可知，在本申请实施例中，终端设备可以充分利用网络设备配置的辅助信息获得邻小区的SSB ID，或者，在网络设备未配置辅助信息的情况下，终端设备自主获取辅助信息来获得邻小区的SSB ID。这些辅助信息包括服务小区与邻小区之间的定时偏差、邻小区的子载波间隔、或者比特位图(bitmap)。
为了更好地理解本申请实施例提供的方案，下文将结合图3描述一个具体例子。在图3中以网络设备为基站、终端设备为UE为例进行描述。如图3所示，包括如下步骤。
S310，UE判断基站是否配置辅助信息，该辅助信息至少包括服务小区与邻小区之间的定时偏差，若否，转到S320，若是，转到S330。
可选地，该辅助信息中还包括邻小区的SCS。
可选地，该辅助信息中还包括邻小区的bitmap。邻小区的bitmap表示邻小区在一个SMTC内传输SSB的时域位置。
可选地，所述邻小区的bitmap表示所述邻小区在SMTC内传输同步信号块的实际时域位置。
S320，UE自主获取辅助信息。
当基站未配置服务小区与邻小区之间的定时偏差时，UE自主获取服务小区与邻小区 之间的定时偏差。
可选地，UE通过小区搜索、和/或定时跟踪，获得该服务小区与该邻小区之间的定时偏差。具体描述参见上文，为了简洁，这里不再赘述。
当基站未配置邻小区的SCS时，UE自主获取邻小区的SCS。
可选地，UE将邻小区的频点所在的频带对应的SCS确定为邻小区的SCS。
如果邻小区的频点所在的频带对应的SCS有两种，则终端设备通过如下方式确定邻小区的SCS：排除两种子载波间隔中的一种子载波间隔，将剩余的另一种子载波间隔作为邻小区的子载波间隔，其中，被排除的子载波间隔对应的同步信号块索引大于频点所在的频带的最大的同步信号块索引；或根据终端设备所处的地理位置，从该两种子载波间隔中选择一种作为该邻小区的SCS。具体描述参见上文，为了简洁，这里不再赘述。
可选地，UE自主获取辅助信息，还包括：终端设备存储历史服务小区和/或历史邻小区的bitmap，如果当前邻小区为历史服务小区或历史邻小区，则将预先存储的bitmap作为当前邻小区的bitmap。
S330，UE根据辅助信息中包含的服务小区与邻小区之间的定时偏差、或者邻小区SCS，或者邻小区bitmap，获取邻小区的SSB ID。
具体地，S330包括如下步骤：
S331，UE根据服务小区的SSB ID、邻小区的SCS、以及服务小区与邻小区之间的定时偏差，获取邻小区的SSB ID。
S331对应于上述实施例中的S220，详细描述请参见上文，这里不再赘述。
S332，UE根据邻小区的bitmap，以及S331中确定的一个SSB ID，获取该邻小区在一个SMTC内所有的SSB ID。
UE获取邻小区的bitmap的具体方式参见上文描述，为了简洁，这里不再赘述。
S340，UE基于获取的邻小区的SSB ID，测量邻小区SMTC内所有实际传输的SSB，获得邻小区测量结果。
可选地，在终端设备完成邻小区的SSB的测量后，可以向网络设备上报邻小区的SSB的测量结果，或者，也可以不向网络设备上报邻小区的SSB的测量结果。本申请实施例对此不做限定。
可选地，UE设定信号功率门限，当当前测量的同步信号块的信号功率小于所述信号功率门限时，降低所述当前测量的同步信号块附近的同步信号块的测量优先级，以便于提高下次测量的同步信号块的信号功率大于或等于所述信号功率门限的概率。
本申请通过设置信号功率门限，降低信号功率较低的同步信号块的测量优先级，从而可以优先测量信号功率较高的同步信号块，可以提高小区测量的效率。
可选地，UE可以向基站上报S340得到的测量结果，也可以不上报。实际应用中，可以根据具体需求确定是否上报。
如图4所示，本实施例还提供一种小区测量的方法400，该方法400包括如下步骤。
S410，获取邻小区的一个同步信号块索引(SSB ID)。
可选地，步骤S410对应于上述实施例中的步骤S220，即可以采用上述实施例中提供的任一种方式来获取邻小区的一个同步信号块索引。
可选地，还可以通过解析邻小区发送的PBCH，获得邻小区的一个同步信号块索引。
S420，获取该邻小区的比特位图，该邻小区的比特位图表示该邻小区在单测量定时配置SMTC内传输同步信号块的时域位置。
具体地，获取该邻小区的比特位图的实现方式有多种，具体描述参见上文相关描述，为了简洁，这里不再赘述。
S430，根据所获取的该邻小区的同步信号块索引，以及该邻小区的比特位图，对该邻小区在该STMC内的其它同步信号块进行测量。
本申请实施例通过邻小区的一个SSB ID和邻小区的bitmap，获得邻小区在SMTC内的所有SSB ID，可以有效提高小区测量的效率，此外，可以降低终端设备的处理复杂度，从而降低终端设备的能耗。
例如，终端设备根据某一个SSB ID推算获得SMTC内所有的SSB ID。换言之，本申请的方案约束一个SMTC内最多解一次PBCH，或者根据服务区的定时和同步信息指示，最多推算一次邻区的SSB ID，避免SMTC内的每个SSB都去解PBCH或者逐个推算邻区的SSB ID。
上文描述了本申请实施例提供的通信方法，下文将描述本申请实施例提供的通信装置。应理解，装置实施例的描述与方法实施例的描述相互对应，因此，未详细描述的内容可以参见上文方法实施例，为了简洁，这里不再赘述。
