Description
本申请实施例涉及通信领域，并且更具体地，涉及测量同步信号的方法和设备。
长期演进(Long Term Revolution，LTE)系统支持单载波操作以及载波聚合(Carrier Aggregation，CA)操作。对于单载波操作，在系统带宽内从频域上看仅分别存在一个主同步信号(Primary Synchronization Signal，PSS)、辅同步信号(Secondary Synchronization Signal，SSS)。对于载波聚合操作，LTE系统的成员载波最大带宽为20MHz，每一个成员载波中在频域上也仅存在一个PSS/SSS信道。特别地，LTE系统的PSS/SSS所占的6个物理资源块(Physical Resource Block，PRB)位于系统带宽的中央位置。
目前，第三代合作伙伴(3rd Generation Partnership Project，3GPP)已经达成共识，网络设备向终端发送包含多个SS块(block)的SS突发组(Burst Set)，每一个SS block内包含PSS、SSS和物理广播信道(Physical Broadcast channel，PBCH)。且SS block在系统带宽内的频率位置不限定于系统带宽的中心频点位置。终端在系统带宽内搜索SS block获取时频同步、获取PBCH信息、进行无线资源管理(Radio Resource Management，RRM)测量。
对于新无线通信(New Radio，NR)系统，可能会支持带宽很大的宽带成员载波，例如带宽为400MHz甚至1GHz的宽带成员载波。在同一个宽带成员载波内，会分布具备多种工作带宽的终端设备，例如系统带宽为400MHz，则可能分布有400MHz的带宽的终端设备，还可能有100MHz、40MHz、10MHz带宽的终端设备。如果在宽带成员载波内仅存在一个SS blcok位置，则具有较小工作带宽的终端设备在其工作带宽内可能不存在SS block。并且对于具备非常大的带宽的宽带成员载波，其不同的频率位置的传播特性可能会有较大的差异。这就需要NR系统中的网络设备在宽带成员载波内向终端设备发送多个同步信号块。
因此，需要提供一种测量同步信号块的方法，满足网络设备在一个宽带成员载波内向终端设备发送多个同步信号块的通信系统对同步信号块的测
量需求。

下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
应理解，本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)或全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、5G系统，或者说新无线(New Radio，NR)系统。
在本申请实施例中，终端设备可以包括但不限于移动台(Mobile Station，MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、用户设备(User Equipment，UE)、手机(handset)及便携设备(portable equipment)、车辆(vehicle)等，该终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，终端设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
本申请实施例所涉及到的网络设备是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置。所述网络设备可以为基站，所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等。在采用不同的无线接入技术的系统中，具有基站功能的设备的名称可能会有所不同。例如在LTE网络中，称为演进的节点B(Evolved NodeB，eNB或eNodeB)，在第三代(3rd Generation，3G)网络中，称为节点B(Node B)等等。
需要说明的是，本申请实施例中，终端设备对同步信号(Synchronization Signal，SS)块(block)进行测量包括但不限于参考信号接收功率(Reference Signal Receiving Power，RSRP)的测量、参考信号接收功率(Reference Signal Receiving Power，RSRP)的测量和接收的信号强度指示(Received Signal Strength Indication)的测量。
图1示出了根据本申请实施例的测量同步信号块的方法。如图1所示，方法100包括：
S110，终端设备对第一小区中传输的多个同步信号块中的至少一个同步信号块进行测量，得到第一测量结果，所述第一小区为所述终端设备的服务小区；
S120，所述终端设备根据所述第一测量结果和目标触发条件，执行与所述目标触发条件相对应的操作，所述目标触发条件为多种触发条件中的一种，每种触发条件对应的操作不同。
可选地，在S110中，终端设备对进行时频同步时使用的同步信号块进行测量得到第一测量结果。在这种情况下，终端设备一开始只需要对当前的SS block进行测量，避免测量多个SS block带来的较高的实现复杂度。
可选地，在S110中，终端设备进行测量的至少一个同步信号块为网络设备配置的一个第一目标同步信号块。例如，终端设备接收网络设备发送的第一指示信息，第一指示信息用于指示所述第一目标同步信号块。并且可以理解的是，第一指示信息指示的这个第一目标同步信号块可以是终端设备在进行时频同步时需要使用的同步信号块。
举例来说，如图2所示出的，服务小区中的宽带成员载波的带宽为400MHz，在该宽带成员载波中需要传输4个SS block，分别为同步信号块1(SS block1)、同步信号块2(SS block2)、同步信号块3(SS block3)和同步信号块4(SS block4)，这4个SS block以频率间隔为100MHz均匀分布。
如果，终端设备检测到SS block1，终端设备使用SS block1进行时频同步，并对SS block1进行测量。或者终端设备接收到的第一指示信息指示SS block2，则终端设备对SS block2进行测量。
可选地，在S120中，如果终端设备确定第一测量结果满足第一触发条件，终端设备测量服务小区中的其他SS block得到第二测量结果或者终端设备上报对服务小区中的其他SS block进行测量的得到的第二测量结果。如果终端设备确定第二测量结果满足第二触发条件，终端设备对邻小区中的同步信号块进行测量或者上报对邻小区中的同步信号块进行测量得到的测量结果。或者终端设备根据第一测量结果和第二测量结果确定第三测量结果，如果终端设备判断第三测量结果满足第三触发条件，终端设备对邻小区中的同步信号块进行测量或者上报对邻小区中的同步信号块进行测量得到的测量结果。
具体地，在一些实施例中，如果终端设备在确定第一测量结果满足第一触发条件之前，没有对服务小区中的其他SS block进行测量，则终端设备对服务小区中的其他SS block进行测量得到第二测量结果，终端设备还可以选择在测量之后将第二测量结果上报给网络设备。如果终端设备在确定第一测量结果满足第一触发条件之前，已经对服务小区中的其他SS block进行了测量得到第二测量结果，则终端设备确定第一测量结果满足第一触发条件时，终端设备直接向网络设备上报第二测量结果。进一步地，当终端设备确定第二测量结果满足第二触发条件，或终端设备确定由第一测量结果和第二测量结果得到的第三测量结果满足第三触发条件时，终端设备对邻小区中的同步信号块进行测量或上报邻小区的同步信号块的测量结果。
由此，终端设备根据对服务小区中的多个SS block的测量结果综合判断服务小区的信号质量，判断结果更为可靠，避免在本小区部分频域资源上信号良好的情况下，提前启动邻小区测量、邻小区测量结果上报或小区切换，提高通信系统的性能。
举例来说，第一触发条件为事件X1(第一测量结果差于第一预设门限值)，当第一测量结果和第一配置值的和小于第一预设门限值时，终端设备认为第一测量结果满足事件X1，当第一测量结果和第一配置值的差大于第一预设门限值时，终端设备认为第一测量结果不满足事件X1。同样的，第二触发条件为事件X2(第二测量结果差于第二预设门限值)，当第二测量结
果和第二配置值的和小于第二预设门限值时，终端设备认为第二测量结果满足事件X2，当第二测量结果和第二配置值的差大于第二预设门限值时，终端设备认为第二测量结果不满足事件X2。或者，第三触发条件为事件X3(第三测量结果差于第三预设门限值)，当第二测量结果和第二配置值的和小于第三预设门限值时，终端设备认为第三测量结果满足事件X3，当第三测量结果和第三配置值的差大于第三预设门限值时，终端设备认为第三测量结果不满足事件X3。并且，上述的第三测量结果可以是第一测量结果和第二测量结果的平均值，或第三测量结果可以是第一测量结果和第二测量结果中的最大值、最小值或中间值。
可选地，在S120中，如果终端设备确定第一测量结果满足第四触发条件，终端设备对服务小区中的其他同步信号块和邻小区中的同步信号块进行测量，或者终端设备向网络设备上报对服务小区中的其他同步信号块和邻小区中的同步信号块进行测量得到的测量结果。
举例来说，网络设备和终端设备可以事先预定或协议规定一个参数，或者网络设备通过信令为终端设备配置一个参数。第四触发条件为第一测量结果差于这个参数。如果第一测量结果好于这个参数，则终端设备认为第一测量结果不满足第四触发条件，如果第一测量结果差于这个参数，则终端设备认为第一测量结果满足第四触发条件。
在上述所有实施例中，可选地，服务小区中的其他同步信号块可以是服务小区中传输的多个同步信号块中除第一目标同步信号块之外的所有同步信号块。以上述的4个SS block为例，如果第一目标同步信号块为SS block2，则服务小区中的其他同步信号块为SS block1、SS block3和SS block4。
或者，服务小区中的其他同步信号块可以是网络指定的同步信号集合中的同步信号块。网络设备向终端设备发送第二指示信息，第二指示信息指示服务小区中的其他同步信号块，例如，可以具体指示同步信号块在频域上的编号，或者具体指示承载同步信号块的频域资源。
或者，服务小区中的其他同步信号块为服务小区中传输的多个同步信号块中对应的频域位置在终端设备的工作带宽内的同步信号块。以上述的4个SS block为例，假设终端设备的工作带宽为250MHz，承载SS block1、SSblock2和SS block3的频域位置在终端设备的工作带宽内，而第一目标同步信号块为SS block1，则服务小区中的其他同步信号块为SS block2和SS
block3。可选地，终端设备的工作带宽可以理解为网络设备配置终端设备能够使用的带宽，或者终端设备能够支持的最大带宽。
可选地，在S120中，如果终端设备确定第一测量结果满足第五触发条件，终端设备对邻小区中的同步信号块进行测量或上报对邻小区中的同步信号块进行测量得到的测量结果。在这种情况下，第一测量结果为终端设备对进行频域同步时使用的同步信号块进行测量得到的测量结果；或第一测量结果为终端设备对服务小区中传输的多个同步信号块中的全部同步信号块进行测量得到的测量结果；或第一测量结果为终端设备对网络设备指定的同步信号块进行测量得到的测量结果，这里网络设备可以向终端设备发送第三指示信息，第三指示信息指示终端设备需要测量的同步信号块；或者第一测量结果为终端设备对工作带宽内的所有同步信号块进行测量得到的测量结果。
需要说明的是，本申请实施例中的多种触发条件，可以是协议规定的，也可以是网络设备和终端设备事先约定的，还可以是网络设备通过信令通知给终端设备的。
