Description

一种SSB测量方法和装置
本申请要求于2019年08月15日提交国家知识产权局、申请号为201910755097.X、申请名称为“一种SSB测量方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及一种同步信号/物理广播信道块((synchronization signal，SS)/(physical broadcast channel，PBCH)block，SSB)测量方法和装置。
背景技术
移动性管理是无线移动通信中的重要组成部分。根据终端设备的状态，移动性管理可以分为两部分：空闲态(RRC_IDLE state)/去激活态(RRC_INACTIVE state)的移动性管理和连接态(RRC_CONNECTED state)的移动性管理。在终端设备处于空闲态/去激活态的情况下，移动性管理包括小区选择/重选(cell selection/reselection)的过程。在终端设备处于连接态的情况下，移动性管理包括小区切换(handover)的过程。无论是小区选择/重选还是小区切换，都是基于移动性测量的结果进行的。因此，移动性测量是移动性管理的基础。
新无线(new radio，NR)系统中的移动性测量涉及两种参考信号，分别为SSB和信道状态信息参考信号(channel state information-reference signal，CSI-RS)。对于基于SSB的测量，网络设备可以通过一个比特图(bitmap)来指示终端设备需要测量的SSB集合。例如，该比特图可以为ssb-ToMeasure，ssb-ToMeasure指示一个频点下终端设备需要测量的SSB集合，终端设备根据ssb-ToMeasure测量该频点下各个小区的SSB集合。
由于一个频点下可能有多个小区(该多个小区可以包括服务小区和服务小区的邻小区)，而各个小区发送的SSB块的位置可能不同，因此ssb-ToMeasure不能很好地反应一个频点上所有小区的SSB发送情况，可能使终端设备漏测服务小区发送的一些SSB，从而导致服务小区的测量结果变差。
发明内容

在第一方面或第二方面的一种可能的实现方式中，第一信息或第二信息携带在无线资源控制(radio resource control，RRC)信令或广播消息中。例如，第一信息可以携带在RRC信令中的servingCellConfigCommon字段，或者可以携带在系统信息块(system information block，SIB)1里的servingCellConfigCommonSIB字段。例如，第二信息可以携带在SIB2和/或SIB4中，或者可以携带在RRC信令中的测量对象(measurement object，MO)中。

为了下述各实施例的描述清楚简洁，首先给出相关概念或技术的简要介绍：
SSB：包括主同步信号(primary synchronization signal，PSS)、辅同步信号(secondary synchronization signal，SSS)、物理广播信道(physical broadcast channel，PBCH)，以及为了解调PBCH所需的解调参考信号(PBCH demodulation reference signal，PBCH-DMRS)。PSS和SSS用于终端设备进行下行同步，包括时钟同步，帧同步和符号同步；获取小区标识(identity，ID)；用于小区信号质量(参考信号接收功率(reference signal received power，RSRP)/参考信号接收质量(reference signal received quality，RSRQ)/信噪比(signal to interference plus noise ratio，SINR))测量，主要是通过SSS信号测量，用于初始波束选择，无线资源管理(radio resource management，RRM)测量等；PBCH承载了主系统信息(master information block，MIB)内容。
目前，终端设备可以根据ssb-ToMeasure测量或接收SSB，而ssb-ToMeasure是per频点指示的。当各个小区发送的SSB块的位置不完全相同时，ssb-ToMeasure不能很好地反应一个频点上所有小区的SSB发送情况。例如，假设频点1包括2个小区，其中服务小区发送的SSB的比特图可以为1101(即未发送第三个SSB)，服务小区的邻小区发送的SSB的比特图可以是1011(即未发送第二个SSB)，此时，为了节省终端功耗，ssb-ToMeasure可以被配置为1001，以保证终端能测量到ssb-ToMeasure指示的所有SSB，但这样会导致UE漏侧服务小区发送的第二个SSB，从而导致服务小区的测量结果变差。
本申请实施提供一种SSB测量方法，终端设备可以根据第一信息在第一测量窗口内测量服务小区发送的SSB，第一信息指示服务小区发送的SSB的时域位置，能够保证终端设备用更准确的服务小区SSB发送信息(第一信息)来进行服务小区的SSB测量，提高服务小区的测量准确度。
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描述。其中，在本申请的描述中，除非另有说明，“至少一个”是指一个或多个，“多个”是指两个或多于两个。另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
为了便于理解，以下结合附图对本申请实施例提供的SSB测量方法进行具体介绍。
如图5所示，本申请实施例提供一种SSB测量方法，包括：
501、网络设备发送第一信息，第一信息指示服务小区发送的SSB的时域位置。
示例性的，第一信息可以是ssb-PositionsInBurst。
502、终端设备接收第一信息，第一信息指示服务小区发送的SSB的时域位置。
对于连接态(connected)的终端设备，服务小区可以是指与终端设备建立RRC连接的小区。connected态的终端设备可以通过接收服务小区发送的RRC信令获取第一信息，例如，第一信息可以携带在RRC信令中的servingCellConfigCommon字段。
对于空闲态/非激活态(idle/inactive)的终端设备，服务小区可以是指终端设备驻留的小区。idle/inactive态的终端设备可以通过接收驻留小区发送的广播消息获取第一信息，例如，第一信息可以携带在SIB1里的servingCellConfigCommonSIB字段。
503、网络设备发送第二信息，第二信息指示终端设备需要测量的邻区发送的SSB集合。
示例性的，第二信息可以是ssb-ToMeasure。
可选的，本实施例中的步骤501与步骤503之间没有必然的执行先后顺序，可以是先执行步骤501，再执行步骤503；也可以是先执行步骤501，再执行步骤503；还可以是同时执行步骤501与步骤503，本实施例对此不作具体限定。
504、终端设备接收第二信息，第二信息指示终端设备需要测量的邻区发送的SSB集合。
idle/inactive态的终端设备可以通过接收驻留小区发送的广播消息获取第二信息，例如，第二信息可以携带在SIB2和/或SIB4中。
connected态的终端设备可以通过接收服务小区发送的RRC信令获取第二信息，例如，第二信息可以携带在RRC信令中的MO中。
可选的，本实施例中的步骤502与步骤504之间没有必然的执行先后顺序，可以是先执行步骤502，再执行步骤504；也可以是先执行步骤504，再执行步骤502；还可以是同时执行步骤502与步骤504，本实施例对此不作具体限定。
505、终端设备根据第一信息在第一测量窗口内测量服务小区发送的SSB。
其中，第一测量窗口是指终端设备进行SSB测量的时间窗口，终端设备只需在第一测量窗口内测量服务小区发送的SSB，无需在第一测量窗口之外进行SSB测量，能够避免终端设备作无谓的测量，减少终端设备的功耗。
终端设备可以通过接收RRC信令获取第一测量窗口的配置参数，第一测量窗口的配置参数可以包括：窗口的周期、窗口的偏移量(offset)以及窗口的持续时长(duration)。
示例性的，第一测量窗口可以是同步信号/物理广播信道块测量定时配置(SS/PBCH block measurement timing configuration，SMTC)窗口。SMTC的配置参数可以携带在RRC信令中的MO中，SMTC窗的配置参数可以包括SMTC timing字段和SMTC duration字段。SMTC timing字段可以指示SMTC窗口的周期与偏移量信息。例如，SMTC窗口的周期可以是5、10、20、40、80或160ms。SMTC窗口的偏移量可以在0到(SMTC窗口的周期-1)ms之间取值，例如，SMTC窗口的偏移量可以在0-4、0-9、0-19、0-39、0-79或0-159ms之间取值。SMTC duration字段可以指示SMTC窗口的长度，例如，SMTC窗口的长度可以是1、2、3、4或5ms。可以理解的是，SMTC窗口的边界可以与服务小区的子帧边界对齐。
对于连接态下的同频测量，网络设备可以为终端设备在一个频点上配置至多两个SMTC窗口，至多两个SMTC窗的偏移量和长度可以相同，但具有不同的周期。若网络设备为终端设备在一个频点上配置了两个SMTC窗口，网络设备可以通过配置信息(例如，list清单)告知终端设备该频点上的各个小区应该适用哪个SMTC窗。如果没有显式地指示一个小区所适用的SMTC窗，则该小区适用于周期更长的SMTC窗。对于连接态下的异频测量和空闲态下的测量，网络设备可以为终端设备在一个频点上配置至多一个SMTC窗口。
第一信息可以包括第一比特图，第一比特图可以包括一个或多个比特位，每个比特位对应一个SSB索引(index)。终端设备根据第一比特图中取值为1的比特位来确定第一SMTC窗口内需要测量的服务小区发送的SSB。具体的，对于第一比特图中的每个比特位，若该比特位的取值为1，终端设备测量该比特位对应的SSB索引所指示的SSB。若该比特位的 取值为0，终端设备可以不测量该比特位对应的SSB索引所指示的SSB。
可选的，第一比特图可以有多种长度，例如第一比特图的长度可以为4、8或64。例如，对于<3GHz的频点，由于SSB突发周期(SS burst)里最多可以有4个SSB位置，因此第一bitmap的长度可以为4。对于3GHz-6GHz的频点，由于SS burst里最多可以有8个SSB位置，因此第一bitmap的长度可以为8，对于>6GHz的频点，由于SS burst里最多可以有64个SSB位置，因此第一bitmap的长度可以为64。
506、终端设备根据第二信息在第二测量窗口内测量邻区发送的SSB。
其中，邻区即终端设备的服务小区的邻区，可以包括与服务小区同频的邻区(即与服务小区处于同一个频点的邻区)，也可以包括与服务小区异频的邻区(即与服务小区处于不同频点的邻区)。与服务小区同频的邻区可以包括一个或多个，与服务小区异频的邻区可以包括一个或多个。
对于连接态下的异频测量，第二测量窗口可以与第一测量窗口不同。例如，网络设备可以为终端设备在不同频点配置不同的SMTC窗口。第二测量窗口的配置参数可以参考步骤505中的相关描述，在此不做赘述。
对于连接态下的同频测量，第二测量窗口与第一测量窗口可以相同或不同。例如，对于连接态下的同频测量，网络设备可以为终端设备在一个频点上配置至多两个SMTC窗口(例如，SMTC1和SMTC2)。终端设备可以在SMTC1内测量服务小区以及与服务小区同频的部分邻区发送的SSB，在SMTC2内测量与服务小区同频的其余邻区发送的SSB。示例性的，假设与服务小区同频的邻区包括3个，分别为邻区1、邻区2和邻区3。终端设备可以在SMTC1内测量服务小区和邻区1发送的SSB，在SMTC2内测量邻区2和邻区3发送的SSB。可以理解的是，测量邻区1发送的SSB时，第二测量窗口为SMTC1，第二测量窗口与第一测量窗口相同，测量邻区2和邻区3发送的SSB时，第二测量窗口为SMTC2时，第二测量窗口与第一测量窗口不同。
第二信息可以是per频点指示的，即第二信息指示一个频点上的全部邻区需要测量的SSB集合，终端设备根据每个频点对应的第二信息测量该频点上的邻区发送的SSB集合。
第二信息可以包括第二比特图，第二比特图可以包括一个或多个比特位，每个比特位对应一个SSB索引。对于第二比特图中的每个比特位，若该比特位的取值为1，终端设备测量该比特位对应的SSB索引所指示的SSB。若该比特位的取值为0，终端设备可以不测量该比特位对应的SSB索引所指示的SSB。与第一比特图类似的，第二比特图也可以包括多种长度，例如，第二比特图的长度可以为4、8和64。
可选的，当服务小区未发送第一信息时，或者终端设备未接收到第一信息时，即不执行步骤501和/或步骤502时，终端设备可以根据第二信息在第一测量窗口内测量服务小区发送的SSB。
可选的，本实施例中的步骤505与步骤506之间没有必然的执行先后顺序，可以是先执行步骤505，再执行步骤506；也可以是先执行步骤505，再执行步骤506；还可以是同时执行步骤505与步骤506，本实施例对此不作具体限定。
基于本申请实施提供的方法，终端设备可以根据第一信息在第一测量窗口内测量服务小区发送的SSB，第一信息指示服务小区发送的SSB的时域位置，能够保证终端设备用更准确的服务小区SSB发送信息(第一信息)来进行服务小区的SSB测量，提高服务小区的 测量准确度。
如图6所示，本申请实施例提供一种SSB测量方法，包括：
601、网络设备发送第一信息，第一信息指示服务小区发送的SSB的时域位置。
参考步骤501的相关描述，在此不做赘述。
602、终端设备接收第一信息，第一信息指示服务小区发送的SSB的时域位置。
参考步骤502的相关描述，在此不做赘述。
603、网络设备发送第二信息，第二信息指示终端设备需要测量的SSB集合。
示例性的，第二信息可以是ssb-ToMeasure，指示终端设备需要测量的SSB集合。终端设备需要测量的SSB集合包括服务小区发送的SSB和邻小区发送的SSB。
第二信息可以携带在RRC信令或广播消息中。相关描述可以参考步骤504，在此不做赘述。
604、终端设备接收第二信息，第二信息指示终端设备需要测量的SSB集合。
参考步骤504的相关描述，在此不做赘述。
605、终端设备根据第一信息和第二信息在第一测量窗口内测量服务小区发送的SSB。
终端设备可以根据第一信息和第二信息的交集在第一测量窗口内测量服务小区发送的SSB。例如，第一信息包括第一比特图(bitmap)，第二信息包括第二比特图，若第一比特图的第N个比特位与第二比特图中的第N个比特位的取值都为1，终端设备测量第N个比特位对应的SSB索引所指示的SSB。其中，N为大于等于0的整数。
在一种可能的设计中，第二比特图中每个比特位对应的SSB索引可以与第一比特图中每个比特位对应的SSB索引可以相同。例如，假设第一比特图包括4个比特位，第一个比特位对应索引为0的SSB，第二个比特位对应索引为1的SSB，第三个比特位对应索引为2的SSB，第四个比特位对应索引为3的SSB。第二比特图包括4个比特位，其中，第一个比特位也对应索引为0的SSB，第二个比特位对应索引为1的SSB，第三个比特位对应索引为2的SSB，第四个比特位对应索引为3的SSB。
举例来说，如图7所示，第一比特图可以包括4个比特位，分别对应索引为0，1，2和3的SSB，第二比特图可以包括4个比特位，分别对应索引为0，1，2和3的SSB，如果第一比特图中各比特位的取值为1011，第二比特图中各比特位的取值为1101，那么终端设备测量第一个比特位和第四个比特位对应的SSB索引(即SSB0和SSB1)对应的SSB。
可选的，当服务小区未发送第二信息时，或者终端设备未接收到第二信息时，即不执行步骤603和/或步骤604时，终端设备根据第一信息在第一测量窗口内测量服务小区发送的SSB。
606、终端设备根据第二信息在第二测量窗口内测量邻区发送的SSB。
参考步骤506的相关描述，在此不做赘述。
可选的，当服务小区未发送第二信息时，或者终端设备未接收到第二信息时，即不执行步骤603和/或步骤604时，终端设备在第二测量窗口内测量邻区发送的全部SSB。
可选的，本实施例中的步骤605与步骤606之间没有必然的执行先后顺序，可以是先执行步骤605，再执行步骤606；也可以是先执行步骤605，再执行步骤606；还可以是同时执行步骤605与步骤606，本实施例对此不作具体限定。
相比仅根据第二信息测量服务小区发送的SSB，根据第一信息和第二信息的交集测量 服务小区发送的SSB，可以避免因第二信息指示的SSB多于第一信息指示的SSB(即服务小区实际发送的SSB)导致终端设备需要对服务小区进行多余测量的问题，从而可以节省终端设备的功耗。
如图8所示，本申请实施例提供一种SSB测量方法，包括：
801、网络设备发送第一信息，第一信息指示服务小区发送的SSB的时域位置。
参考步骤501的相关描述，在此不做赘述。
802、终端设备接收第一信息，第一信息指示服务小区发送的SSB的时域位置。
参考步骤502的相关描述，在此不做赘述。
803、终端设备根据第一信息在第一测量窗口内测量服务小区发送的SSB。
参考步骤505的相关描述，在此不做赘述。
可选的，若网络设备未发送第一信息，或者终端设备未接收到第一信息，终端设备在第一测量窗口内测量服务小区发送的全部SSB。
804、终端设备在第二测量窗口内测量邻区发送的全部SSB。
即若终端设备未接收到用于指示终端设备需要测量的邻区发送的SSB集合的指示信息(例如，ssb-ToMeasure)，终端设备在第二测量窗口内测量邻区发送的全部SSB。
第二测量窗口的相关描述可以参考步骤506，在此不做赘述。
可选的，本实施例中的步骤803与步骤804之间没有必然的执行先后顺序，可以是先执行步骤803，再执行步骤804；也可以是先执行步骤803，再执行步骤804；还可以是同时执行步骤803与步骤804，本实施例对此不作具体限定。
基于本申请实施提供的方法，若终端设备未接收到用于指示终端设备需要测量的邻区发送的SSB集合的指示信息(例如，ssb-ToMeasure)，终端设备可以根据第一信息在第一测量窗口内测量服务小区发送的SSB，第一信息指示服务小区发送的SSB的时域位置，能够保证终端设备用更准确的服务小区SSB发送信息(第一信息)来进行服务小区的SSB测量，提高服务小区的测量准确度。
