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)系统、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、非授权频段上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、非授权频段上 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。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
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，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
本申请实施例的方法可以应用于非授权频谱的通信中，也可以用于授权频谱的通信。
非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。为了让使用非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，通信设备在非授权频谱上进行通信时，可以遵循先听后说(Listen Before Talk，LBT)的原则，即，通信设备在非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；如果通信设备在非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。可选地，LBT的带宽是20MHz，或为20MHz的整数倍。最大信道占用时间(Maximum Channel Occupancy Time，MCOT)，可以是指LBT成功后允许使用非授权频谱的信道进行信号传输的最大时间长度，不同信道接入方案下有不同的MCOT。MCOT的最大取值例如可以为10ms。应理解，该MCOT为信号传输占用的时间。信道占用时间(Channel Occupancy Time，COT)，可以是指LBT成功后使用非授权频谱的信道进行信号传输的时间长度，该时间长度内信号占用信道可以是不连续的。其中，一次COT最长可选地不可以超过例如20ms，该COT内的信号传输占用的时间长度不超过MCOT。
NR系统中的公共信道和信号(如同步信号和广播信道)，可以通过多波束扫描的方式覆盖整个小区，便于小区内的UE接收。同步信号(SS，synchronization signal)和物理广播信道(Physical Broadcasting Channel，PBCH)的多波束发送可以是通过定义SS/PBCH(SSB)簇集(burst set)(本申请实施例中的簇集也可以称为簇，也即SS/PBCH簇集可以称为SSB簇)实现的。
其中，一个SS/PBCH burst set可以包含一个或多个同步信号块(SS/PBCH block，SSB)。一个SSB用于承载一个波束的同步信号和广播信道。因此，一个SS burst set可以包含的SSB的数量可以等于小区发送SSB的波束。一个SS burst set包括的SSB的最大数目L可以与系统的频段有关。
例如，对于3GHz以内的频带，L等于4；对于3GHz到6GHz之间的频带，L等于为8；对于6GHz到52.6之间的频带，L等于64。
可选地，一个SSB中可以包含一个符号的主同步信号(Primary synchronization signal，PSS)，一个符号的(Secondary synchronization signal，SSS)和两个符号的NR-PBCH(New Radio Access Technology-Physical broadcast channel，物理广播信道)，例如，如图2所示。其中，PBCH所占的时频资源中，可选地可以包含解调参考信号(Demodulation Reference Signal，DMRS)，用于PBCH的解调。
可选地，SS/PBCH burst set内所有的SSB可以在一定的时间窗(例如，5ms)内发送，并以一定的周期重复发送，该周期可以通过高层的参数SSB定时(SSB-timing)进行配置，例如，周期可以包括5ms，10ms，20ms，40ms，80ms，160ms等。
图3所示为不同的子载波(Subcarrier space，SCS)间隔下SSB的分布图样。以15kHz子载波间隔，L＝4为例，一个时隙(slot)包含14个符号(symbol)，可以承载两个SSB。在5ms时间窗内的前两个时隙内分布4个SSB。
其中，L为最大的SSB的个数，实际发送的SSB的个数可以小于L。实际发送的SSB的位置通过比特映射的形式，通过系统信息通知给终端设备。
实际发送的SSB的个数和位置由基站决定。例如，在授权频谱的6GHz以下的频段，SSB burst中包含的SSB最多有8个，SSB索引的取值为0-7。基站通过8比特的比特映射通知UE具体的SSB发送位置。8比特的比特映射分别对应SSB索引＝0-7，每一个比特代表一个SSB的发送与否情况，以供UE做速率匹配。如图4所示，SSB的图样中，实际发送的SSB的索引为0,2,4,6，则系统信息中携带的8比特的比特映射为“10101010”。
SSB索引可选地可以用于帧同步，以及也可以用于终端设备获得SSB的QCL关系。在不同的时间接收到的SSB的索引相同，可以认为它们之间具有QCL关系。
其中，当两个参考信号(比如SSB)是QCL的时候，可以认为这两个参考信号的大尺度参数(如多普勒时延、平均时延、空间接收参数等)是可以相互推断的，或者可以认为是类似的。在测量时UE可以将具有QCL关系的SSB做滤波处理，作为波束级别的测量结果。
在NR-U系统中，例如对于一个主小区(Pcell)，网络设备可以发送发现参考信号(Discovery Reference Signal，DRS)信号用于接入、测量等，DRS可以至少包括SSB。可选地，DRS可以包括SSB、SIB1对应的PDCCH、承载SIB1的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，还可以包括寻呼小区等。与SSB类似，DRS信号也可以按照一个块(block)发送，该块内的信号是具有(Quasi Co-Loacted,QCL)关系的。应理解，在本申请实施例中，DRS也可以包括其他类型的信息，本申请实施例对此不做具体限定。
考虑到非授权频谱上信道使用权获得的不确定性，在SSB的发送过程中，由于存在LBT失败的可能，在预定的时刻可能无法成功发送SSB。可以增加SSB的发送机会，在一个DRS传输窗(也可以称为SSB传输窗)内，网络设备配置的DRS的候选位置个数Y大于网络设备实际发送的DRS的个数X。也就是说，对于每个DRS传输窗，网络设备可以根据该DRS传输窗内的LBT的检测结果来确定使用该Y个候选位置中可用的X个候选位置来传输DRS。
假设SSB发送的最大数目是8，在一个时间窗(也可以称为传输窗或SSB传输周期)内有Y＝64个候选发送位置。如图5所示，所示，当SSB索引0的发送时间之前进行的LBT失败，继续进行信道侦听，在SSB索引4之前进行的LBT成功，则从SSB索引4开始发送剩余的SSB，并在发送完SSB索引7之后，再接着发送之前没有发送成功的SSB索引0-3。根据LBT成功的时刻，SSB的实际发送时间可能位于在初始或备选发送时间。如图5所示只是一种增加发送机会的方法，还有其他的方法，在此不再赘述。
对于非授权载波的新无线(New Radio-unlicensed，NR-U)中定义的SSB的发送方式，由于UE需要通过在候选发送位置上接收到的SSB获得帧同步，需要针对候选发送位置定义扩展SSB索引(extended SSB index)。举例说明，以L＝8,Y＝20为例，由于最大8个SSB可能在20个候选位置上发送，SSB携带的索引需要扩展到0到Y-1，以便终端设备获得接收到的SSB的位置，进一步获得帧同步。
另外，在NR中，通过SSB索引还可以获得QCL信息。在NR-U中，由于采用扩展SSB索引，一种获得SSB的QCL信息的方法可以是扩展SSB索引对L取模(mod L)，具有相同结果的扩展SSB索引对应的SSB具有QCL关系。如图6所示，扩展SSB索引为0,8,16,24的SSB具有QCL关系。
在这种假设下，对于某个波束的SSB(其中，波束相同的SSB具有QCL关系)，其在Y个候选发送位置上的位置也就确定了。这样带来的问题是，网络设备实际发送的SSB的QCL属性与候选发送位置具有绑定关系，具有某种QCL关系的SSB并不能在候选发送位置中的任意位置发送。由于非授权频谱上的信道使用是基于抢占的，对SSB的发送时间的限制会对信道占用提出更高的要求，降低占用信道的使用效率。
如图7所示，L＝8，Y＝20，当网络设备实际发送的SSB的QCL对应的SSB索引为4,5,6,7，那么它们在Y个候选中的位置为12,13,14,15。如果网络设备进行LBT成功后，必须等到扩展SSB索引为12时才能开始发送，造成扩展SSB索引为8,9,10,11的位置上的信道占用的浪费。
上述问题可以通过扩展SSB索引为12的候选发送位置之前才开始进行LBT，如果LBT成功，就可以在扩展SSB索引为12开始发送SSB，例如，如图8所示。这种方式的缺点是限制了网络设备进行LBT的时刻，减少了网络设备可以在DRS窗口内进行LBT尝试的机会。
为此本申请实施例提供了以下的方案，可以避免信道的浪费并且在非授权频谱的场景下，可以增加网络设备进行LBT尝试的机会。
图9是根据本申请实施例的无线通信方法200的示意性流程图。该方法200包括以下内容中的至少部分内容。本申请实施例的方法可以用于授权频谱中，也可以用于非授权频谱中。
在210中，网络设备向终端设备发送指示信息，所述指示信息指示SSB簇中实际传输的SSB。
其中，本申请实施例中提到的SSB簇可以是指单个SSB传输周期(可以称为SSB传输窗或时间窗)中最多可以传输的SSB。SSB簇包括的SSB的数量最大可以是上文提到的L。
可选地，本申请实施例中的所述指示信息可以承载于系统信息中。
具体地，该指示信息可以承载于系统信息块(System Information Block，SIB)1或主信息块(Master Information Block，MIB)中。
其中，本申请实施例中承载该指示信息的系统信息可以属于SSB所属的DRS中，当时也可以不属于该DRS。
在指示信息承载于系统信息中时，终端设备可以处于连接态，也可以处于空闲态。
可选地，在指示信息承载于系统信息中时，一段时间内的系统信息中承载的该指示信息的内容可以是不变的。
可选地，在本申请实施例中，所述系统信息为系统信息块1SIB1或主信息块MIB。
其中，在指示信息通过SIB1承载时，可以如下方式所示：
ssb-PositionsInBurst SEQUENCE{
inOneGroup BIT STRING(SIZE(8)),
groupPresence BIT STRING(SIZE(8))OPTIONAL
上述方式表示将最多64个SSB最多分成8个组，groupPresence指示哪些组中有实际传输的SSB，其中的8比特比特映射中，1代表该组内有实际传输的SSB，0代表没有。inOneGroup指示在每个组中，实际传输的SSB所在的位置，其中的8比特的比特映射中，1代表该位置上的SSB传输，0代表不传输。
可选地，在本申请实施例中，在所述终端设备处于空闲态时，所述指示信息承载于SIB1中。
可选地，在本申请实施例中，该指示信息可以承载于RRC信令中。
具体地，SSB簇中实际传输的SSB可以是半静态配置的，可以承载于用于半静态配置的消息中，例如，可以承载于RRC信令中。
在指示信息承载于RRC信令中时，该终端设备可以处于连接态。
在该指示信息承载于RRC信令中时，具体实现可以如下所示：
ssb-PositionsInBurst CHOICE{
shortBitmap BIT STRING(SIZE(4)),
mediumBitmap BIT STRING(SIZE(8)),
longBitmap BIT STRING(SIZE(64))
}
其中，根据不同的频段，最大的SSB个数L可以为4、8、64，通过相应的短比特映射(short bitmap)、中比特映射(medium bitmap)、长比特映射(long bitmap)，指示其中实际传输的SSB的位置，1代表该位置上的SSB传输，0代表不传输。
可选地，本申请实施例中，所述指示信息为SSB簇中的SSB位置(ssb-PositionsInBurst)信息。此时，该指示信息可以承载于SIB1或RRC信令中。
可选地，在本申请实施例中，所述指示信息通过比特映射的方式指示所述SSB簇中实际传输的SSB。
例如，SSB簇中SSB的数量是8个，指示信息包括的比特为11001100，则代表8个SSB中索引为0,1,4和5的SSB被实际传输。
当然，在本申请实施例中，也可以通过其他的方式来指示SSB簇中实际传输的SSB，例如，指示信息通过携带实际传输的SSB的索引的方式指示SSB簇中实际传输的SSB。
可选地，在本申请实施例中，网络设备可以通过多种方式发送该指示信息，例如，即通过SIB1，也通过RRC发送该指示信息。
可选地，在本申请实施例中，采用不同的方式发送的指示信息可以具有不同的用途。
具体地，利用SIB1发送的指示信息(指示实际传输的SSB)可以用于空闲态终端设备的测量，当该终端设备与网络建立RRC链接后，网络设备可以通过RRC信令发送指示信息(指示实际传输的SSB)，用于终端设备进行速率匹配。
例如，UE通过SIB1得到的ssb-PositionsInBurst主要用于idle UE的测量，当UE与网络建立RRC链接后，基站可以通过RRC信令配置另一个ssb-PositionsInBurst，其主要用于UE进行速率匹配。
可选地，在本申请实施例中，如果终端设备利用某一种方式指示的指示信息确定QCL关系，则网络设备也可以利用该种方式指示的指示信息确定QCL关系，可以使得网络设备和终端设备对于SSB的QCL关系的理解保持一致。
可选地，具体采用哪种方式来确定QCL关系可以是预设在终端设备上的，也可以是由网络设备配置的，其中，配置信息可以承载在MIB或SIB中。
例如，网络设备可以指示终端设备根据SIB1还是RRC信令中的指示信息获得实际传输的SSB的数量信息，从而确定SSB的QC关系。
在220中，根据所述指示信息中指示的实际传输的SSB的数量，所述网络设备确定待发送的SSB的QCL关系。
具体地，所述网络设备可以将所述待发送的SSB中携带的扩展SSB索引对所述数量取模，以确定所述待发送的SSB的QCL关系。其中，对数量取模得到的数值一样的扩展SSB索引对应的SSB具有QCL关系。
本申请实施例中的SSB携带的扩展SSB索引表征着该SSB所占用的候选发送位置，终端设备可以根据该扩展SSB索引进行帧同步。其中，该扩展SSB索引还可以称为候选发送位置索引。
在230中，网络设备向终端设备发送SSB。
可选地，在本申请实施例中，在终端设备发送SSB之前，可以执行LBT操作，在LBT成功的情况下，可以发送SSB。
可选地，在本申请实施例中，根据所述待发送的SSB的QCL关系，确定所述待发送的SSB的发送位置。
其中，网络设备在执行LBT操作时，可以根据与待发送的SSB准共址的SSB所对应的扩展SSB索引，确定进行LBT操作的起始时间。
例如，如图10所示，SSB的候选发送位置为16个，扩展SSB索引为从0到15，SSB簇包括的SSB的数量为8，实际传输的SSB的数量N为4，则扩展SSB索引0和扩展SSB索引4具有QCL关系，也即是QCL的。
在本申请实施例用于非授权频谱的情况下，如图10，如果网络设备在t0时刻(SSB 传输周期的起始点)执行LBT成功，则可以在扩展SSB索引为0的位置处发送SSB，则后续的SSB传输周期，可以在扩展SSB索引为0,4,8,12对应的候选发送位置发送SSB，以实现与t0处发送的SSB准共址。
在240中，终端设备接收网络设备发送的指示信息，所述指示信息指示同步信号块SSB簇中实际传输的SSB。
可选地，在本申请实施例中，在指示信息通过多种方式发送的情况下，如果多种方式发送的指示信息指示的实际传输的SSB和/或其数量不同，则终端设备可以根据其中一种方式发送的指示信息确定实际传输的SSB和/或其数量。
例如，在网络设备通过RRC和SIB1均发送该指示信息的情况下，如果RRC中的指示信息指示的实际传输的SSB的数量不同于SIB1中的指示信息指示的实际传输的SSB的数量，则可以根据SIB1中的指示信息指示的实际传输SSB的数量为准。
在250中，根据所述实际传输的SSB，所述终端设备确定实际传输的SSB的数量。
根据指示信息指示的实际传输的SSB，可以获得其中的实际传输的SSB的个数N。
例如，当L＝8时，通过ssb-PositionsInBurst指示的比特映射为11001100，则可以确定实际发送的SSB的个数N＝4。
在260中，终端设备接收网络设备发送的SSB。
可选地，在本申请实施例中，终端设备可以根据盲检测的方式检测SSB。
可选地，在本申请实施例中，终端设备可以根据待检测的SSB的QCL关系来执行SSB的检测。
可选地，在本申请实施例中，终端设备可以根据实际传输的SSB和/或其数量执行SSB的检测。
可选地，在本申请实施例中，本申请实施例提到的指示信息指示SSB簇中实际传输的SSB，则可以用于终端设备确定(可以是大致判断)SSB的候选发送位置中哪些候选发送位置发送有SSB。
在270中，终端设备根据实际传输的SSB数量，确定接收到的SSB的QCL关系。
具体地，在本申请实施例中，终端设备可以将所述接收到的SSB中携带的扩展SSB索引对所述数量取模，以确定所述接收到的SSB的准共址QCL关系。对应相同的取模结果的SSB具有QCL关系。
可选地，在本申请实施例中，利用扩展SSB索引对实际传输的SSB取模可以理解为将一个SSB传输周期的候选发送位置按照实际传输的SSB的数量进行分组，每组候选发送位置包括的候选发送位置的数量等于实际传输的SSB的数量。每组候选发送位置均可以用于传输SSB，网络设备如果在某一组候选发送位置检测到信道空闲，则可以利用该组候选发送位置发送SSB。
在任一个SSB传输周期，均可以利用一组候选发送位置发送该SSB，其中一个SSB传输周期发送的至少一个SSB与另一个SSB传输周期发送的至少一个SSB是具有QCL关系的。
例如，如图10所示，SSB的候选发送位置为16个，扩展SSB索引为从0到15，SSB簇包括的SSB的数量为8，实际传输的SSB的数量N为4，则可以理解为可以将16个候选发送位置划分为4个组，组1的扩展SSB索引为0-3，组2的扩展SSB索引为4-7，组3的SSB索引为8-11，组4的SSB索引为12-15。每个SSB传输周期可以分别利用一组候选发送位置发送SSB。不同的SSB传输周期，候选发送位置组中的相同位置发送的SSB是具有QCL关系的。
应理解，本申请实施例并不限于以上的描述，例如，可以采用类似于图5所示的方式发送SSB。
例如，假设SSB候选发送位置的最大数量为64，实际传输的SSB的数量为4，则扩展SSB索引为0,4,8,12…60的候选发送位置上发送的SSB具有QCL关系，类似地，扩 展SSB索引为1,5,9,13…61的候选发送位置上发送的SSB具有QCL关系，扩展SSB索引为2,6,10,14…62的候选发送位置上发送的SSB具有QCL关系，扩展SSB索引为3,7,11,15…63的候选发送位置上发送的SSB具有QCL关系，如果网络设备在扩展SSB索引为21之前检测到了信道空闲，则可以在扩展SSB索引为21,22,23和24的位置处发送SSB。
在依据实际传输的SSB的数量，确定SSB的QCL关系的情况下，实际传输的SSB可以是连续的。
在该种情况下，指示信息可以无需真正指示SSB簇中实际传输的SSB，这是由于假设一个SSB传输周期中SSB候选发送位置是64个，实际传输的SSB的数量为4个，则可以将64个候选发送位置分成16组，每组均可以发送该4个SSB，则此时，网络设备在该每组候选发送位置之前如果检测到了SSB，则可以利用该组候选发送位置发送该4个SSB，在下一个SSB传输周期内，在任一组候选发送位置之前检测到了SSB，则可以在该组发送4个SSB，该4个SSB分别与上一周期的SSB具有QCL关系。
由此，在采用比特映射的方式指示实际传输的SSB的情况下，可以采用固定位置的比特指示实际传输的SSB。
例如，假设SSB簇包括8个SSB，实际传输的SSB的数量为4个，则可以采用8个比特中的前4个比特指示实际传输的SSB，如果实际传输的SSB的数量为5个，则可以采用8个比特中的前5个比特指示实际传输的SSB。
可选地，在本申请实施例中，终端设备根据所述接收到的SSB的QCL关系，执行针对所述接收到的SSB的滤波处理。
具体地，在测量时终端设备可以将具有QCL关系的SSB做滤波处理，作为波束级别的测量结果空闲态的终端设备可以根据该测量结果，选择某个波束的SSB绑定的随机接入信道(Random Access Channel，RACH)资源发送接入。因此，QCL关系的获得对于空闲态终端设备的结果较为重要。
从网络设备角度而言，可以根据其在SIB1中所指示的ssb-PositionsInBurst信息，来保证发送的SSB之间的QCL关系，从而与终端设备确定的QCL关系的结果保持一致。
在本申请实施例中，根据实际传输的SSB的数量确定SSB的QCL关系，如图7所示，如果采用SSB簇包括的SSB的数量(本申请实施例中提到的L)确定QCL关系，可能造成网络设备在检测到信道空闲时，需要等待较长的时间才能发送与已发送的SSB具有QCL关系的SSB，而采用实际传输的SSB的数量确定SSB的QCL关系，则会避免网络设备需要等待较长的时间才能发送该SSB，例如，在如图7所示的情况下，如果采用实际传输的SSB确定SSB的QCL关系，则可以候选发送位置索引为0处即可以发送SSB。在保证终端设备准确获得SSB之间QCL关系的同时，避免了信道占用起始位置与SSB可传输起始位置之间信道资源无法被有效利用的问题，继而提升了非授权频段下系统资源的利用效率。
因此，在本申请实施例中，终端设备通过指示信息中指示的SSB簇中实际传输的SSB，获取实际传输的SSB的数量，并基于该实际传输的SSB的数量确定QCL关系，可以避免SSB簇中SSB的数量确定QCL关系带来的信道浪费的问题，以及借用指示实际传输的SSB的指示信息，确定SSB的QCL关系，可以避免需要发送一条额外的指示信息(例如，承载于MIB，SIB或RRC信令中)用于指示用于确定SSB的QCL关系所采用的数量，从而可以降低信令开销。
应理解，图9所示的方法中各步骤的描述先后顺序或者序号大小不代表各种步骤的执行先后顺序。
例如，210和230可以是同时执行的。240和260可以是同时执行的。270可以先于260执行。
