背景技术
新无线(New Radio，NR)系统中支持免授权频谱上的数据传输，通信设备在免授权频谱上进行通信时，需要基于先听后说(Listen Before Talk，LBT)的原则，即，通信设备在免授权频谱的信道上进行信号发送前，需要先进行信道侦听(或称为信道检测)，只有当信道侦听结果为信道空闲时，通信设备才能进行信号发送；如果通信设备在免授权频谱的上进行信道侦听的结果为信道忙，则不能进行信号发送。
在进行小区测量时，终端设备可以将具有准共址(Quasi Co-Located，QCL)关系的同步信号块(Synchronization Signal/PBCH Block，SSB或SS/PBCH Block)做滤波处理。因此，终端设备如何在免授权频谱上确定SSB的QCL关系，以完成滤波等操作，是一项亟待解决的问题。

具体实施方式
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，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
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)、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
示例性的，本申请实施例应用的通信系统100如图1所示。该通信系统100可以包括网络设备110，网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。可选地，该网络设备110可以是GSM系统或CDMA系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备120。作为在此使用的“终端设备”包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一终端设备的被设置成接收/发 送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
可选地，终端设备120之间可以进行终端直连(Device to Device，D2D)通信。
可选地，5G系统或5G网络还可以称为新无线(New Radio，NR)系统或NR网络。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。
可选地，该通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
应理解，本申请实施例中网络/系统中具有通信功能的设备可称为通信设备。以图1示出的通信系统100为例，通信设备可包括具有通信功能的网络设备110和终端设备120，网络设备110和终端设备120可以为上文所述的具体设备，此处不再赘述；通信设备还可包括通信系统100中的其他设备，例如网络控制器、移动管理实体等其他网络实体，本申请实施例中对此不做限定。
免授权频谱是国家和地区划分的可用于无线电设备通信的频谱，该频谱可以被认为是共享频谱，即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求，就可以使用该频谱，可以不向政府申请专有的频谱授权。为了让使用免授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存，需要基于LBT的原则，即，通信设备在免授权频谱的信道上进行信号发送前，需要先进行信道侦听(或称为信道检测)，只有当信道侦听结果为信道空闲时，通信设备才能进行信号发送；如果通信设备在免授权频谱的上进行信道侦听的结果为信道忙，则不能进行信号发送。且为了保证公平性，在一次传输中，通信设备使用免授权频谱的信道进行信号传输的时长可以不超过最大信道占用时间(Maximum Channel Occupation Time，MCOT)。
可以看到，由于免授权频谱上的信道资源是共享的，而通信设备使用这些共享资源时需要先侦听到空闲信道才能对侦听到的空闲信道加以利用。这种情况下，由于通信设备LBT成功的位置是不可预期的，如果LBT失败，则会造成SSB的发送失败或接收失败，因此，很难保证SSB周期性发送及接收的固定位置。
鉴于此，免授权频谱接入(NR-Based Access to Unlicensed Spectrum，NR-U)中提出了提供多个SSB发送的候选位置的方案，以便终端设备LBT成功后仍然有足够的SSB发送的候选位置可以用来发送SSB，从而避免LBT失败对SSB的接收造成的影响。如图2所示，预配置了16个SSB传输的候选位置，通信设备在进行第一次LBT时失败，之后，通信设备进行第二次LBT，LBT成功。因此，第二次LBT之后的SSB传输的候选位置可以用于传输SSB，第一次LBT和第二次LBT之间的SSB传输的候选位置不能用于传输SSB，即在这16个SSB传输的候选位置上最多可以传输9个SSB。
在终端设备进行小区测量时，具有QCL关系的SSB之间可以做滤波处理，不具有 QCL关系的SSB之间如果做滤波处理，则滤波出来的结果没有任何意义。
目前，在授权频谱上，相同SSB编号的SSB之间具有QCL关系。也就是说，在进行小区测量，终端设备可以将具有相同SSB编号的SSB做滤波处理，以作为波束(beam)级别的测量结果。而编号不同的SSB之间，终端设备认为它们之间不具有QCL关系，所以终端设备可以将编号不同的SSB作为不同的beam处理。
为了进行滤波等测量操作，以保证小区测量的准确性，因此，终端设备如何在免授权频谱上确定SSB的QCL关系，是一项亟待解决的问题。
鉴于此，本申请实施例提出了一种无线通信的方法，可以效确定SSB的QCL关系。
图3是根据本申请实施例的无线通信的方法200的示意性流程图。图3所述的方法可以由终端设备，该终端设备例如可以为图1中所示的终端设备120。如图3所示，该方法200可以包括以下内容中的至少部分内容。
在210中，终端设备从网络设备接收第一指示信息，该第一指示用于指示第一数目Q1，第二指示信息用于指示第二数目Q2。
在220中，终端设备在第一指示信息和第二指示信息中确定目标指示信息，并根据目标指示信息确定终端设备的服务小区的SSB之间的QCL关系。
其中，Q1和Q2可以用于确定服务小区的SSB之间的QCL关系。Q1和Q2除了可以用于确定服务小区的SSB之间的QCL关系之外，还可以用于确定服务小区的其他同步信号之间的QCL关系，比如，Q1和Q2可以用于确定信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)。
可选地，在本申请实施例中，Q1可以等于Q2。
可选地，在本申请实施例中，Q1可以不等于Q2。
为了描述方便，将目标指示信息指示的数目称为Q，即Q为用于最终确定服务小区的SSB之间的QCL关系的有效数目。例如，若终端设备确定的目标指示信息为Q1，则Q＝Q1。
网络设备可以通过多种方式向终端设备指示Q，例如，网络设备可以通过主信息块(Master Information Block，MIB)向终端设备指示服务小区可以使用的Q(小区级别)。
再例如，网络设备可以通过系统信息块(System Information Block，SIB)1指示服务小区可以使用的Q(小区级别)。
再例如，网络设备可以通过SIB1指示服务小区所在频点使用的Q(频点级别)。
再例如，网络设备可以通过SIB2指示服务小区可以使用的Q(小区级别)。
再例如，网络设备可以通过SIB2指示服务小区所在频点使用的Q(频点级别)。
再例如，网络设备可以通过SIB3指示终端设备进行同频小区重选时服务小区可以使用的Q(小区级别)。
再例如，网络设备可以通过SIB3指示终端设备进行同频小区重选时指示服务小区所在频点使用的Q(频点级别)。
再例如，网络设备可以通过无限资源控制(Radio Resource Control，RRC)重配置消息指示服务小区可以使用的Q(小区级别)。
再例如，网络设备可以通过RRC重配置消息指示服务小区所在频点可以使用的Q(频点级别)。
网络设备在向终端设备指示Q之前，网络设备可以先确定Q。应理解，本申请实施例对网络设备确定Q的具体实现方式不作限定。示例性地，Q可以是协议规定预设在网络设备上的。
需要说明的是，当终端设备通过上述多种方式获得指示服务小区可以使用的数目(小区级别)时，终端设备期望以不同方式获得的指示服务小区可以使用的数目是相同的。也就是说，终端设备不期望通过不同的方式获得不同的指示服务小区可以使用的数目Q。类似地，当终端设备通过上述多种方式获得指示服务小区所在频点可以使用的数目(频 点级别)时，终端设备期望以不同方式获得的指示服务小区所在频点可以使用的数目是相同的。
在一种可能的实施例中，若Q1和Q2的级别相同，即Q1和Q2都为频点级别或小区级别的，且Q1＝Q2，则终端设备可以将Q1或Q2确定为Q。
在另一种可能的实施例中，Q1或Q2的级别可以不同，比如，Q1为服务小区可以使用的数目，Q2为服务小区所在频点可以使用的数目。在这种情况下，终端设备可以根据第一规则在第一指示信息和第二指示信息中确定目标指示信息。
下面通过四个实施例详细描述终端设备根据第一规则，在第一指示信息和第二指示信息中确定目标指示信息的实现方式。
实施例1
第一规则可以为：网络设备通过MIB或者SIB1向终端设备指示服务小区可以使用的第一数目Q1，且通过SIB2或SIB3向终端设备指示服务小区所在频点可以使用的第二数目Q2时，目标指示信息可以为承载于MIB或者SIB1的第一指示信息，Q＝Q1。
可选地，第一规则可以用于同频小区重选。例如，第一规则可以用于同频小区重选时对服务小区的SSB按照Q1做QCL假设。
实施例1的技术方案相当于终端设备通过MIB或SIB1获得了小区级别的第一数目Q1，当终端设备需要做同频小区重选时，终端设备又从SIB2或SIB3获得了同频小区重选相关的参数，该同频小区重选相关的参数可以包括但不限于频点级别的用于同频小区重选的第二数目Q2。此时，当网络设备考虑了同频的其他小区特征后，向终端设备指示了个各个小区都可以使用的Q2，由于Q1是实际的当前服务小区可以使用的数目，Q2是考虑了频点级别的数目，因此Q2可以不等于Q1。在这种情况下，对于服务小区来说，Q1是更加准确的数目。所以，终端设备可以将Q1作为有效的服务小区数目。
实施例2
第一规则可以为：网络设备通过MIB或者SIB1向终端设备指示服务小区可以使用的第一数目Q1，且通过SIB2或SIB3向终端设备指示服务小区所在频点可以使用的第二数目Q2时，目标指示信息可以为承载于SIB2或SIB3的第二指示信息，Q＝Q2。
可选地，第一规则可以用于同频小区重选。例如，第一规则可以用于同频小区重选时对服务小区的SSB按照Q2做QCL假设。
实施例2的技术方案相当于终端设备先通过MIB或SIB1获得了小区级别的第一数目Q1，当终端设备需要做同频小区重选时，终端设备又从SIB2或SIB3获得了同频小区重选相关的参数，该同频小区重选相关的参数可以包括但不限于频点级别的用于同频小区重选的第二数目Q2。在这种情况下，为了保证同频小区重选时各个小区采用相同的数目，以保证各个小区做同频小区重选的公平性，对于服务小区来说，终端设备可以在做同频小区重选时使用Q2作为服务小区可以使用的有效数目。
可选地，终端设备可以在服务小区的其他过程中使用Q1，例如终端设备可以在无线链路管理过程中使用Q1。
实施例3
第一规则可以为：网络设备通过MIB或者SIB1向终端设备指示服务小区可以使用的第一数目Q1，且通过RRC重配置消息向终端设备指示服务小区所在频点可以使用的第二数目Q2时，目标指示信息可以为承载于MIB或者SIB1的第一指示信息，Q＝Q1。
可选地，网络设备可以通过测量对象配置信息，或者，RRC重配置消息可以为测量上报配置信息。
可选地，第一规则可以用于同频小区测量。例如，第一规则可以用于同频小区测量时对服务小区的SSB按照Q1做QCL假设。
实施例3的技术方案相当于终端设备通过MIB或SIB1获得了小区级别的第一数目Q1，当终端设备需要做同频小区测量时，终端设备又从RRC重配置消息获得了同频小区 测量相关的参数，该同频小区测量相关的参数可以包括但不限于频点级别的用于同频小区测量的第二数目Q2。此时，当网络设备考虑了同频的其他小区特征后，向终端设备指示了个各个小区都可以使用的Q2，由于Q1是实际的当前服务小区可以使用的数目，Q2是考虑了频点级别的数目，Q2可以不等于Q1。在这种情况下，对于服务小区来说，Q1是更加准确的数目。所以，终端设备可以将Q1作为有效的服务小区数目。
实施例4
第一规则可以为：网络设备通过MIB或者SIB1向终端设备指示服务小区可以使用的第一数目Q1，且通过RRC重配置消息向终端设备指示服务小区所在频点可以使用的第二数目Q2时，目标指示信息可以为承载于RRC重配置消息中的第二指示信息，Q＝Q2。
可选地，第一规则可以用于同频小区测量。例如，第一规则可以用于同频小区测量时对服务小区的SSB按照Q2做QCL假设。
实施例2的技术方案相当于终端设备通过MIB或SIB1获得了小区级别的第一数目Q1，当终端设备需要做小区测量时，终端设备又从RRC重配置消息获得了同频小区重选相关的参数，该同频小区测量相关的参数可以包括但不限于频点级别的用于同频小区测量的第二数目Q2。在这种情况下，为了保证同频小区测量时各个小区采用相同的数目，以保证各个小区做同频小区测量的公平性，对于服务小区来说，终端设备可以在做同频小区测量时使用Q2作为服务小区可以使用的有效数目。
可选地，Q1可以在服务小区的其他过程中使用，例如终端设备可以在无线链路管理过程中使用Q1。
在终端设备确定了目标指示信息，也即确定了Q之后，终端设备可以基于Q，确定服务小区的多个SSB之间的QCL关系。
具体而言，当终端设备检测到两个SSB，这两个SSB的编号分别为M1和M2，如果M1 mod Q＝M2 mod Q，则终端设备可以确认这两个SSB之间具有QCL关系。
结合图4举例说明。图4中有20个SSB，编号分别为0、1、2……19，Q＝8。在此情况下，编号为0的SSB、编号为8的SSB以及编号为16的SSB之间具有QCL关系。编号为1的SSB、编号为9的SSB和编号为17的SSB之间具有QCL关系。
可选地，SSB的编号可以为该SSB在一个SSB集合中，在时域上的排序。该SSB集合可以包括同一个服务小区的SSB或者多个服务小区的SSB。
可选地，SSB的编号可以为该SSB在属于同一个服务小区的SSB中的时域上的排序。
应理解，在本申请实施例中，“第一”和“第二”仅仅为了区分不同的对象，但并不对本申请实施例的范围构成限制。
还应理解，本申请实施例仅示出了网络设备通过两种方式向终端设备指示用于确定SSB之间的QCL关系的数目，但本申请并不限于。网络设备可以通过三种以及三种以上的方式向终端设备指示用于确定SSB之间的QCL关系的数目，此时，终端设备可以根据第一规则，在多个指示信息中确定目标指示信息，即在多个用于确定SSB之间的QCL关系的数目中确定最终用于定SSB之间的QCL关系的数目。
本申请实施例，当终端设备接收到指示确定服务小区的SSB之间的QCL关系的数目的两个指示信息时，终端设备可以基于第一规则，在两个指示信息中确定目标指示信息，从而可以有效确定有效的用于确定SSB的QCL关系的数目。只有当有效的用于确定SSB之间的QCL关系的数目确定后，终端设备在免授权频谱上才能完成滤波等测量操作，从而保证小区重选和小区测量的准确性。
