如图2所示，SSB的结构包括：PSS(NR-PSS)、SSS(NR-SSS)、PBCH(NR-PBCH)、PBCH-DMRS。其中，PSS以及SSS的功能是实现符号(symbol)级别的同步，以及完成物理层小区标识(Physical Cell Identity，PCI)的确定。PBCH包含小区的主信息块(Master Information Block，MIB)以及部分其余信息。PBCH-DMRS包含了部分SSB-index信息(低三位bits)。
2、同步栅格(Synchronization Raster)
在UE刚开机后进行小区搜索时，只能根据运营商以及UE支持的频段检测SSB 信号，进行下行时频同步。由于全局频率栅格的粒度较小导致NR-ARFCN的取值范围较大，如果直接根据全局频率栅格进行盲检，则同步时延会比较大。为了有效的降低此过程的同步时延，定义了同步栅格的概念，并通过全局同步信道号(Global Synchronization Channel Number，GSCN)来限定搜索范围。如表1所示，定义了同步栅格的范围：在0-3000MHz范围内，同步栅格为1200kHz；在3000-24250MHz范围内，同步栅格为1.44MHz；在24250-100000MHz范围内，同步栅格为17.28MHz。与NR绝对无线频率信道号(NR Absolute Radio Frequency Channel Number，NR-ARFCN)类似，GSCN同样对0-100GHz范围的频段做了定义，每个GSCN对应一个SSB的检测频点。
表1
需要说明的是，仅支持子载波间隔(Sub-Carrier Space，SCS)间隔信道栅格的工作频带的默认值为M＝3。
3、PBCH
因为SSB的内部结构是协议标准化的，因此，当UE在特定的同步频点搜到同步信号后，就可以尝试对SSB进行解码。其中，SSB里面包含的最重要的信息就是MIB。其中，MIB包含：
系统帧号(System Frame Number)：完整的帧号需要10bit，而MIB的有效载荷(Payload)中帧号只有高位6bit，低位的4bit在PBCH传输块中的非MIB比特中传送；
初始接入流程中下行信号的子载波间隔(Sub-Carrier Spacing Common)：指示SIB1/OSI/初始接入的Msg2/Msg4/寻呼消息的子载波间隔；
SSB子载波偏移量(Ssb-Sub Carrier Offset)：SSB的最低子载波和与其最近的PRB之间的子载波间隔数；
DMRS-Type A-Position：PDSCH DMRS参考信号的配置；
PDCCH-ConfigSIB1：SIB1_PDCCH的配置，包括控制资源集(CORESET)和搜索空间配置；
小区禁止信息：RRC的接入控制参数，标识该小区是否被禁止；
频内小区的小区重选信息(intra FreqReselection)：RRC接入控制参数，标识小区是否允许同频重选；
spare：保留bit位。
并且，PBCH除了MIB信息还包含了一些其他信息，如图3所示，PBCH中包含的bits：
A+1～A+4：增加的是4bit帧号信息，获得系统帧号的低位4bit后，结合前MIB中系统帧号的6bit信息，就会得到整个10bit的帧号信息；
A+5：增加半帧信息bit，该bit指示是前半帧还是后半帧；
A+6～A+8：如果最大的SSB Index L＝64(即F>6GHz)，A+6～A+8标识SSB Index的高3位，否则，A+6：Kssb的高1位，A+7/A+8：保留bit。
4、小区搜索
UE在开机或进行小区切换时需要用到初始搜索，其目的是获得小区的下行同步：
(1)时间同步检测(检测出同步信号位置，循环前缀(Cyclic Prefix，CP)类型，小区ID号等)；
(2)频率同步检测(利用PSS、SSS等信号进行频偏估计，进而对频偏进行纠正)。当然，初始搜索的一个最主要的功能是找到可以使用的网络，即UE根据其所支持的工作频段以及协议规定的同步信号快编号(GSCN)进行全网频段的盲搜。
只有进入到一个小区的覆盖范围内，UE才能搜索到该小区。UE不仅需要在开机时进行小区搜索，为了支持移动性，UE会不停的搜索小区(测量SSB)，取得同步并估计该小区的接收质量，从而决定是否进行切换(handover，当UE处于RRC_connected态)或者小区重选(cell re_selection，当UE处于RRC_IDLE态或RRC_INACTIVE态)。
NR一共定义了1008个不同的PCI 其中，PSS对应为3个候选m序列，携带部分小区标识(cell ID)信息。SSS对应为336个候选m序列，携带部分cell ID信息。
5、小区测量与上报
移动通信网络中当UE要切换至信号更强的小区、在载波聚合中要添加新载波(CC)时需要测量服务小区和邻小区的信号强度或质量(矩阵，即参考信号接收功率(Reference Signal Received Power，RSRP)或参考信号接收质量(Reference Signal Receiving Quality，RSRQ)。这就要求UE的测量及时和准确，以保持无线链路质量。
NR网络中引入了利用同步信号(SS)和物理广播信道(PBCH)构成的SS/PBCH块(SSB)做为小区(信号)测量对象。一个Brust中SSB的数量取决于工作频率。例如工作频率(fc)<3GHz(FR1)时SSB为4；工作频率(fc)＝3GHz(FR1)<6 GHz(FR1)时SSB为8；而当工作频率(fc)>6GHz(FR2)时SSB为64。
小区SSB的周期可配置为5,10,20,40,80或160ms；UE不需要对小区信号进行周期性测量因为SSB可以根据信道条件配置适当的测量周期。这可以帮助避免不必要的测量和减少UE的能源消耗。协议引入了基于SSB的RRM测量时间配置窗口(称为SMTC窗口)，UE通过SMTC获得SSBs的测量周期和时间。
a)对于服务小区，其在服务小区的公共信息(ServingCellConfigCommon)来为UE配置SSB，首先通过比特位图(bitmap)的方式为UE配置了在一个SSB burst内需要测量的SSBs，SSB的周期和发送功率。
从时间域的角度来看SSB的RRC配置同步信号块的测量时间配置(SSB-Measurement Timing Configuration，SSB-MTC)，在这些时刻UE应该去测量SSB，这里配置了SSB测量的周期和偏移量，其中周期从5subframe到160subframe，在每一个周期测量的时间长度为1subframe到5subframe不等。
b)SMTC(SSB-MTC)测量
SMTC为针对每一个频点配置的，即如果两个邻区的频段是一样的，那么他们的SMTC的配置就是一样的。如果一个小区希望修改SMTC的配置，那么与它相同频段的SMTC的配置也同样会更改。
为了匹配不同小区的不同同步信号块周期，允许连接态同频测量时配置两套SMTC参数用于给定小区测量，即SMTC2。例如，出了基本的SMTC配置外，还可以再配置一套较为密集的测量窗口供服务小区以及特定小区列表内所指示的小区利用。
SMTC2与SMTC1的频段还是一样的。如果配置了SMTC2，只有极少一部分小区是根据SMTC2来测量，引入SMTC2的原因是基于不同小区覆盖问题(比如small cell)。而且，SMTC1的周期一定要是SMTC2的周期的倍数。
c)测量上报
UE对邻区的SSB进行测量后，需要将测量后的结果发送给服务小区。其中，上报配置包括：
触发上报原则：周期性上报或一系列事件的处罚规则；
参考信号(Reference Signal，RS)类型：SSB或信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)；
测量报告形式：例如上报的小区最大数和波束数量。
其中，网络可以配置UE基于SSB上报的信息有：
每个SSB的测量结果；
每个小区的测量结果；
基于SSB Index的测量结果。
6、Light SSB
为了实现基站端的节能，提出使用处于节能模式的基站只发送专用参考信号(Dedicated Reference Signal，DRS)信息。DRS可以是现有SSB的一部分。即，可以只发送PSS以及SSS，或者，只发送PSS或SSS。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的SSB测量方法进行详细地说明。
UE会对周边的小区进行测量，从而估计该小区的信号质量。在此过程中，协议规定UE需要将测量的小区ID，以及SSB index等信息上报给服务小区，从而更好地进行移动性的管理。由于SSB index信息是在PBCH，以及PBCH-DMRS中获得的。因此，在这种情况下，对于发送light SSB的节能基站(不包含PBCH)，如何获得该小区SSB index的信息是需要被解决的。
本申请实施例提供一种SSB测量方法，UE可以检测节能基站发送的第一信息，以执行节能小区的SSB测量，该第一信息包括以下至少一项：第一信号，第一信号由第二信号和有效载荷组成，第一信号中显式携带有SSB索引信息，第二信号包括以下至少一项：PSS和SSS；第三信号，第三信号由PSS和SSS组成，第三信号中隐式携带有SSB索引信息；第四信号，第四信号包括以下至少一项：PSS和SSS，PSS和/或SSS在不同的频域位置上。本方案中，UE在检测节能基站发送的SSB时，可以检测节能基站发送的第一信息，该第一信息中显式或隐式携带了SSB索引信息，即UE可以从检测的第一信息中获得SSB索引信息，以执行节能小区的SSB测量，因此本方案实现了在light SSB下通过显式或隐式的方式使得UE获得所需要的SSB索引信息，从而便于UE进行SSB测量及上报。

可选地，本申请实施例中，上述有效载荷与PSS和/或SSS在同一个符号上。
可选地，本申请实施例中，上述有效载荷可以在两个符号上，两个符号包括PSS所在符号和SSS所在符号。
可选地，本申请实施例中，上述SSB索引信息可以由有效载荷单独携带，有效载荷中不包括DMRS。
可选地，本申请实施例中，上述SSB索引信息可以由DMRS单独携带。

其中，对于基站而言，节能基站可以预先在不同的频域位置上配置PSS和/或SSS，且不同频域位置上的PSS和/或SSS具有不同的索引或者索引组。服务基站通过RRC信令或者下行信号将节能小区的频域位置与PSS和/或SSS的对应关系告知给UE。
对于UE而言，UE在不同的频域位置上进行盲检，并根据服务基站告知的节能基站的频域位置与PSS和/或SSS的对应关系，得到SSB索引信息。

可以理解，通过在light SSB的符号上添加有效载荷，以显式携带SSB索引信息。和/或，通过子小区标识与SSB索引信息相对应，且多个子小区标识对应同一个主小区标识的方式隐式确定SSB索引信息。和/或，通过SSB索引信息与频域位置相关联，从而间接获得SSB索引信息。

示例性地，假设小区1有4个波束，且该小区的子小区标识为4,5,6,7。则sub-cell ID mod N(4)＝0,1,2,3。因此，子小区标识4,5,6,7分别对应SSB index 0,1,2,3。

步骤202b2、UE在第一时刻测量节能小区的SSB的RSRP，并在最大RSRP的SSB对应的SSB周期中的位置，执行节能小区的SSB测量。
可以理解，UE可以在第一时刻测量light SSB的RSRS，并找到最大RSRP的SSB，然后在最大RSRP的SSB对应的位置检测SSB。
示例性地，UE在第一时刻接收到4的light SSB。并测得第二个SSB(SSB 2)的RSRP最好，若SSB周期为20ms，则UE在SSB 2后20ms的位置继续测量SSB2的RSRP，并根据多次测量的结果在层3进行处理，并将处理结果上报给UE所在服务小区。
本申请实施例中，在UE无法直接或间接得到SSB索引信息时，UE可以通过第一规则，即在多个时刻或第一时刻测量SSB的RSRP，并向UE所在服务小区上报测量结果，以便于该服务小区根据该测量结果执行相关操作。
