Description

无线通信的方法、终端设备和网络设备 技术领域
本申请实施例涉及通信领域，具体涉及一种无线通信的方法、终端设备和网络设备。
背景技术
在第五代移动通信技术新空口(5-Generation New Radio，5G NR)***中，同步信号块(Synchronization Signal/Physical Broadcast Channel block，SSB)的索引(index)可以周期性地发送，在一个SSB周期内，SSB的发送位置是确定的，终端设备可以根据接收的SSB的索引确定SSB的发送位置。
在非授权频谱上，通信设备遵循“先听后说(Listen Before Talk，LBT)”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，只有当信道侦听结果为信道空闲时，该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信道上的信道侦听结果为信道忙，该通信设备不能进行信号发送。
在5G NR***应用到非授权频谱上时，网络设备必须LBT成功获得信道使用权之后，才能发送SSB，也就是说，在非授权频段，实际发送SSB的起始位置并不确定，终端设备接收到SSB后，不能获知SSB之间的准共址(Quasi-co-located，QCL)关系，也就不能对具有QCL关系的SSB进行合并、滤波处理，影响***性能。因此，如何确定SSB之间的QCL关系是一个值得研究的问题。

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***，例如：全球移动通讯(Global System of Mobile communication，GSM)***、码分多址(Code Division Multiple Access，CDMA)***、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)***、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)***、LTE频分双工(Frequency Division Duplex，FDD)***、LTE时分双工(Time Division Duplex，TDD)***、先进的长期演进(Advanced long term evolution，LTE-A)***、新无线(New Radio，NR)***、NR***的演进***、非授权频段上的LTE(LTE-based access to unlicensed spectrum，LTE-U)***、非授权频段上的NR(NR-based access to unlicensed spectrum，NR-U)***、通用移动通信***(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信***、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信***或其他通信***等。
通常来说，传统的通信***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***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***。
示例性的，本申请实施例应用的通信***100如图1所示。该通信***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***或CDMA***中的基站(Base Transceiver Station，BTS)，也可以是WCDMA***中的基站(NodeB，NB)，还可以是LTE***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***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***(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***(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***或5G网络还可以称为新无线(New Radio，NR)***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***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***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/***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***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***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。
应理解，本文中术语“***”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。
在NR***中，SSB可以在一定的时间窗(例如，5ms的时间窗)内发送，并且可以以一定的周期重复发送，可选地，该周期例如可以为5ms，10ms，20ms，40ms，80ms，160ms等。一个时间窗内，网络设备能够发送的SSB的最大数量为L，实际发送的SSB的个数可以小于L。
对于终端设备来说，通过接收到的SSB可以得到该SSB的索引(index)，SSB index对应该SSB在该时间窗内的相对位置，终端设备根据该SSB index和物理层广播信道(Physical Broadcast Channel，PBCH)中承载的半帧指示，确定该SSB在无线帧中的位置，从而获得帧同步。
对于QCL关系，终端设备可以假设相同的SSB index的SSB具有QCL关系，即，若在不同的时刻，终端设备接收到的SSB的index相同，则认为它们之间具有QCL关系。
在NR-U***中，由于非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再对信道加以利用，这种情况下，很难保证在固定位置周期性地发送及接收SSB。因为发送设备LBT成功的时序位置是不可预期的，由于LBT失败的原因，很有可能造成SSB的发送及接收失败。
因此，在NR-U***中，提供多个SSB的候选位置，以便于LBT成功后，仍然有足够的SSB的候选位置可以用来发送SSB，以及相应地避免LBT失败对SSB接收造成影响。具体地，在一个时间窗内，可以配置Y个SSB候选位置，在这Y个SSB传输的候选位置上最多能传L个SSB，其中，L小于Y，并且SSB只能在发送设备获得可用信道后才可发送。
以5ms的时间窗，L为4，Y为20为例，如图2所示，若网络设备在候选位置12之前LBT成功，则在候选位置12开始发送SSB index为0～3的SSB，因此在NR-U***中，SSB的实际发送位置可能从该Y个候选位置的任意一个开始。因此，如果终端设备需要通过候选位置上接收到的SSB获得帧同步，在一种实现方式中，可以定义扩展SSB index(extended SSB index)，用于指示该Y个候选位置，此情况下，SSB携带的index扩展至0至Y-1，这样，终端设备可以根据接收到的SSB携带的扩展SSB index确定SSB在时间窗内的实际发送位置，进而获得帧同步。
也就是说，SSB携带的扩展SSB index可以理解为该SSB在时间窗内的位置索引，也可称为SSB位置索引，或者说，SSB携带的扩展SSB index用于指示该SSB的实际发送位置在该Y个候选位置中的位置索引。
为了使得终端设备确定SSB之间的QCL关系，在一种实现方式中，可以假设一个时间窗内SSB的扩展SSB索引对L取模的结果相同的SSB具有QCL关系，基于这种假设，对于同一个波束的SSB，则只能在特定的候选位置发送了。如图3所示，以L＝8，Y＝32为例，extended SSB index对8取模的结果相同的SSB具有QCL关系，其中，extended SSB index取0-31，则可以确定extended SSB index为0,8,16,24的SSB之间具有QCL关系。
但是，上述方案带来的问题是，网络设备实际发送的SSB的QCL属性和候选位置具有绑定关系，也就是说，满足QCL关系的SSB只能在固定的几个位置上发送，并不能在候选位置中的任一位置发送，由于非授权频谱上的信号使用是基于LBT机制的，这种限制势必降低信道的使用效率。
结合图4，以L＝8，Y＝20为例进行说明，若网络设备实际发送的SSB的数量为4，该4个SSB的SSB index为4,5,6,7，基于上述假设，该SSB索引为4的SSB只能在候选位置4,12上发送，若网络设备在候选位置8之前LBT成功，则该网络设备需要等到候选位置12才能开始发送该SSB索引为4,5,6,7的4个SSB，造成候选位置8-11上的信道不能被使用从而造成资源浪费。另一方面，在NR-U***中，如果候选位置8-11之间的时频资源不被占用，则可能导致有其他设备在该时频资源内LBT侦听成功并占用信道，继而影响候选位置12之后的SSB传输。
有鉴于此，本申请实施例提供了一种新的确定方式，可以用于确定SSB的QCL关系，并有利于降低对非授权频谱上的资源的浪费。
图5是根据本申请实施例的无线通信的方法的示意性流程图，该方法200可以由图1所示的通信***中的终端设备执行，如图5所示，该方法200包括以下内容中的至少部分内容：
S210，终端设备在非授权频谱上接收第一同步信号块SSB；
S220，根据所述第一SSB的物理广播信道PBCH中的第一比特域和/或第二比特域，确定所述第一SSB的扩展SSB索引和/或用于确定准共址QCL关系的第一参数N，其中，所述N为正整数，所述第一比特域在所述PBCH中的比特位置与授权频谱上的PBCH中的子载波间隔比特域的比特位置相同，所述第二比特域在所述PBCH中的比特位置与授权频谱上的PBCH中的子载波偏移比特域的比特位置部分或完全相同；
S230，根据所述第一SSB的扩展SSB索引和所述N，确定所述第一SSB与其他SSB的QCL关系。
在本申请实施例中，为了终端设备确定SSB之间的QCL关系，该终端设备可以获 得第一参数N，并基于接收的第一SSB的扩展SSB索引和该N确定接收该第一SSB和其他SSB的QCL关系。在一些实现方式中，该终端设备可以假设扩展SSB索引对N取模的结果相同的SSB之间是具有QCL关系的。进一步地，该终端设备可以将具有QCL关系的SSB作滤波处理，作为beam级别的测量结果，有利于提升***性能。
可选地，在本申请实施例中，SSB的扩展SSB index可以理解为该SSB在用于发送SSB的时间窗内的位置索引，可称为SSB位置索引；或者说，SSB携带的扩展SSB index用于指示该SSB的实际发送位置在该Y个候选位置中的位置索引。
可选地，在本申请实施例中，所述N可以为网络设备实际发送的SSB的数量，或者，也可以为其他用于确定SSB的QCL关系的参数，本申请实施例对此不作限定。
可选地，在本申请实施例中，该第一SSB包括以下中的至少一种信号：
主同步信号(Primary Synchronization Signal，PSS)，辅同步信号(Secondary Synchronization Signal，SSS)，物理层广播信道(Physical Broadcast Channel，PBCH)。
可选地，在本申请实施例中，所述终端设备可以根据接收到的第一SSB的PBCH中的第一比特域和第二比特域中的至少一个，确定该扩展SSB索引和N中的至少一个，其中，该PBCH中的第一比特域可以对应于该授权频谱上的PBCH中的子载波间隔比特域，该PBCH中的第二比特域可以对应授权频谱上的PBCH中的子载波偏移比特域的比特位置部分或全部。
为便于理解和说明，对授权频谱上的PBCH中承载的信息做个简单介绍：
非授权频谱上的PBCH信道承载的信息包括来自高层的A比特信息和物理层(层1)相关的信息，其中，层1相关的信息包括***帧号(System Frame Number，SFN)、半帧指示、SSB index等。
具体地，PBCH信道承载的信息包括来自高层的主信息块(Master Information Block，MIB)，共A比特，即
Figure PCTCN2019076773-appb-000001
以及来自层1的8比特信息，
Figure PCTCN2019076773-appb-000002
其中，A比特的MIB包括SFN的6比特，子载波间隔信息(subCarrierSpacingCommon)的1比特，SSB的子载波偏移信息(ssb-SubcarrierOffset)的4比特，解调参考信号(Demodulation Reference Signal，DMRS)相关信息、调度***信息块(System Information Block，SIB)的物理下行控制信道(Physical Downlink Control Channel，PDCCH)的资源信息等，其中，还包含了1个空闲比特。
其中，ssb-SubcarrierOffset比特域包括4比特，用于指示SSB与非SSB的信道或信号之间的物理资源块物理资源块(physical resource block，PRB)栅格之间的偏移k SSB，该偏移k SSB包括0-11个子载波或者0-23个子载波，ssb-SubcarrierOffset比特域可以对应于参数k SSB的低4位。subCarrierSpacingCommon用于指示SIB1,用于初始接入的消息2/消息4(Msg.2/4)，寻呼(paging)消息和广播***消息(broadcast SI-messages)的子载波间隔。
层1的8比特信息，即
Figure PCTCN2019076773-appb-000003
中，
Figure PCTCN2019076773-appb-000004
为SFN的最低4位；
Figure PCTCN2019076773-appb-000005
为半帧指示；当L SSB＝64时，
Figure PCTCN2019076773-appb-000006
为SSB index的最高3位，否则，
Figure PCTCN2019076773-appb-000007
为参数k SSB的最高位，
Figure PCTCN2019076773-appb-000008
为保留比特，或者说空闲比特。其中，L SSB为最大的SSB个数，对应于前文所述的L，k SSB为SSB的子载波偏移信息。当***频带小于6GHz时，即L SSB小于64时，层1相关的信息有2比特的空闲比特。
在本申请实施例中，在非授权频谱上接收的SSB的PBCH中可以包括第一比特域和第二比特域，该第一比特域可以对应于授权频谱上的PBCH中的子载波间隔比特域(即subCarrierSpacingCommon)，该PBCH中的第二比特域可以对应授权频谱上的PBCH中的子载波偏移比特域(ssb-SubcarrierOffset)的比特位置的部分或全部。
例如，该第一比特域可以对应subCarrierSpacingCommon的一个比特，该第二比特域可以对应ssb-SubcarrierOffset的4个或5个比特中的部分比特或全部比特。
可以理解，以上，授权频谱上的PBCH中的各个比特域所占的比特数仅为示例，上述各个比特域所占的比特数也可以根据实现需求和协议规定等进行调整，本申请实施例对此不作限定。
在基于非授权频谱的通信***中，例如NR-U***，SSB的子载波间隔与调度SIB1的PDCCH的子载波间隔通常是相同的，因此，在NR-U***中，可以不需要通过subCarrierSpacingCommon来指示SIB1，用于初始接入的Msg.2/4，paging消息和广播***消息的子载波间隔，而直接可以认为其与SSB的子载波间隔是相同的。因此，该subCarrierSpacingCommon对应的非授权频谱上的PBCH中的第一比特域可以用于指示扩展SSB索引和所述N的至少部分信息。
在基于非授权频谱的通信***中，例如NR-U***，SSB与非SSB的信道或信号之间的PRB栅格是对齐的，或者其偏移为有限的偏移，此情况下，用于指示k SSB的比特域包含的比特数可以减少，那么多余的比特可以用于指示扩展SSB索引或N的至少部分信息。具体地，在NR***中，授权频段可能分配给不同的运营商，SSB的PRB栅格是预定义的，运营商在利用分配的授权频段时，可以灵活的设置非SSB的PRB栅格，而不必受预定义的SSB的PRB栅格的限制，从而更加灵活和高效的利用频谱资源。然而在NR-U***中，由于是非授权频谱，不存在频谱分配的问题，此情况下，可以规定SSB与非SSB的信道或信号之间的PRB栅格是对齐的，或者其偏移为有限的取值。从而能够降低k SSB的比特域所占的比特数，进一步可以使用该ssb-SubcarrierOffset比特域中的部分或全部比特指示该扩展SSB索引和所述N的至少部分信息。
以ssb-SubcarrierOffset为例，若该SSB与非SSB的信道或信号之间的PRB栅格是对齐的，此情况下，该ssb-SubcarrierOffset的5比特都可以用于指示扩展SSB索引或N中的至少部分信息，或者，若SSB与非SSB的信道或信号之间的PRB栅格采用有限的偏移，则该ssb-SubcarrierOffset的1-4个比特可以用于指示扩展SSB索引或N中的部分信息，扩展SSB索引或N的其他部分可以通过其他信息指示，例如通过空闲比特或DMRS序列指示等。
应理解，非授权频谱上的PBCH中的第一比特域在一些情况下也可以称为subCarrierSpacingCommon比特域，或者也可以根据该第一比特域实际指示的内容确定，例如，在该第一比特域用于指示N时，该第一比特域可以称为N比特域，或者在该第一比特域用于指示扩展SSB索引的部分时，该第一比特域可以称为extended SSB index比特域，本申请实施例对此不作限定。
类似地，非授权频谱上的PBCH中的第二比特域在一些情况下也可以称为ssb-SubcarrierOffset比特域，或者也可以根据该第二比特域实际指示的内容确定，例如，在该第二比特域用于指示N时，该第二比特域可以称为N比特域，或者在该第二比特域用于指示扩展SSB索引的至少部分时，该第二比特域可以称为extended SSB index比特域，本申请实施例对此不作限定。
可选地，在本申请实施例中，该扩展SSB索引可以通过PBCH中的第一比特域和/或第二比特域承载。
例如，若该扩展SSB索引包括5比特信息，此情况下，可以通过该第一比特域承载该5比特中的1比特，通过该第二比特域承载该5比特中的其他4个比特中的至少部分比特，或者，通过该第二比特域承载该5比特中的2比特，通过其他信息，例如空闲比特或DMRS信令承载该5比特中的其他比特。
可选地，在本申请实施例中，该N可以通过PBCH中的第一比特域和/或第二比特域承载。
例如，可以通过该第一比特域承载该N，假设该第一比特域长度为1比特，则可以根据该第一比特域的取值，确定该N的取值，例如可以在第一比特域的取值为0时，确定N＝2，在第一比特域的取值为1时，确定N＝4。
又例如，可以通过该第二比特域承载该N，假设该第二比特域长度为4比特，则可以根据该第二比特域中的2个比特承载该N，例如可以在该2个比特的取值为00时，确定N＝2，在该2个比特的取值为01时，确定N＝4，在该2个比特的取值为10时，确定N＝6，在2个比特的取值为11时，确定N＝8。
再例如，如该N占P个比特，该P个比特中的P1个比特可以通过第一比特域承载，该P个比特中的其他比特通过该第二比特域承载，或者通过空闲比特承载等。
可选地，在本申请实施例中，该终端设备也可以根据PBCH的DMRS序列，确定该N。例如，可以根据该PBCH的DMRS序列和第二对应关系，确定该N。
在一个实施例中，该第二对应关系可以为多个DMRS序列和多个N的取值的对应关系，从而该终端设备可以根据接收到的第一SSB的PBCH对应的DMRS序列，确定对应的N。
在另一个实施例中，该第二对应关系也可以是多个DMRS序列和多个N的取值和扩展SSB索引中的部分比特的组合之间的对应关系。
例如，在该第二对应关系中，第一DMRS序列指示扩展SSB索引的二进制低两位为10，且N为2，第二DMRS序列指示扩展SSB索引的二进制低两位为11，且N为4，从而，该终端设备可以根据接收到的第一SSB的PBCH对应的DMRS序列，确定对应的扩展SSB索引的部分比特和N。也就是说，可以将N和可扩展SSB索引中的部分比特进行联合编码，并与DMRS序列进行对应。
可选地，在其他实施例中，该N可以是预配置的，或者由网络设备配置的。
可选地，在一些实施例中，S220可以具体包括：
根据所述第一SSB的PBCH中的第一比特域和/或第二比特域，结合所述PBCH的解调参考信号DMRS序列和/或所述PBCH中的第三比特域，确定所述第一SSB的扩展SSB索引和/或所述N，其中，所述第三比特域在所述PBCH中的比特位置与授权频谱上的PBCH中的空闲比特域的比特位置部分或完全相同。
也就是说，可以通过第一比特域和第二比特域至少一个，以及DMRS序列和第三比特域中的至少一个承载所述第一SSB的扩展SSB索引的部分或全部信息。以及可以通过第一比特域和第二比特域至少一个，以及DMRS序列和第三比特域中的至少一个承载所述N的部分或全部信息。
以下，结合具体实施例，即实施例1～实施例3，具体说明扩展SSB索引和N的承载方式。
在以下实施例中，假设扩展SSB索引占K个比特，N占P个比特，第一比特域为Q个比特，第二比特域为M个比特，其中，K，P，Q，M为正整数。
实施例1，通过第一比特域承载所述扩展SSB索引和N的至少部分信息。
在一些实施例中，DMRS序列可以用于确定扩展SSB索引的部分比特，具体地，该DMRS序列确定所述扩展SSB索引中的K 1个比特，所述K 1，K 1＜K，其中，该K 1个比特位为该扩展SSB索引的K个比特中的低K 1个比特或高K 1个比特。具体地，该DMRS序列和扩展SSB索引的K 1个比特可以具有第一对应关系，通过不同的DMRS序列指示该K1个比特的不同取值。
该K个比特中其他K-K 1个比特中的至少一个可以通过该第三比特域承载，或者也可以通过第一比特域承载。
该N可以承载在第一比特域中，或者也可以承载在第三比特域中，或者也可以通过第一比特域和第三比特域共同承载。
在一个具体例子中，K＝5，K 1＝3，该K 1个比特位为该K个比特中的低3个比特，第 一比特域为1个比特，即Q＝1，如图6所示，该DMRS序列可以用于确定该扩展SSB索引的5个比特中的低3个比特(B0～B2)，该第三比特域可以用于承载该扩展SSB索引的高2个比特(B3～B4)，该第一比特域可以指示N，例如，可以在第一比特域的取值为0时，确定N＝2，在第一比特域的取值为1时，确定N＝4。
应理解，在该实施例中，上述各个比特域的长度，以及扩展SSB索引和N所占的比特数，以及指示方式仅为示例，例如，本申请实施例也可以通过第三比特域和第一比特域共同承载该扩展SSB索引的部分比特，本申请实施例并不限于此。
因此，本申请实施例中，通过利用在NR-U***中不再有意义的第一比特域(对于subCarrierSpacingCommon)承载扩展SSB索引和N的部分信息，进而终端设备根据根据该第一比特域获得扩展SSB索引和N的信息，从而终端设备可以根据扩展SSB索引和N的信息，确定SSB的QCL关系。
实施例2，通过第二比特域承载所述扩展SSB索引和N的至少部分信息。
由上文描述可知，在基于非授权频谱的通信***中，通过规定SSB和非SSB的信道的PRB栅格对齐或者有限取值的偏移，可以节省该ssb-SubcarrierOffset中的部分或全部比特(对应第二比特域)来承载该扩展SSB索引和N中的至少部分信息。
假设该ssb-SubcarrierOffset的该M个比特中的M1比特可以用于承载该扩展SSB索引和N中的至少部分信息，即该第二比特域为M1个比特，可选地，该M可以为4或5，对应地，M1可以为4或5，或者也可以为1至3中的任一值。
作为一个实施例，DMRS序列可以用于确定扩展SSB索引的部分比特，具体地，该DMRS序列可以用于确定所述扩展SSB索引中的K 1个比特，具体确定方式可以参考前述实施例的相关描述，这里不再赘述。
该K个比特中其他K-K 1个比特可以通过该第二比特域和/或第三比特域承载。
所述N可以通过该第二比特域和/或第三比特域承载。
在一个具体例子中，K＝5，K 1＝3，该K 1个比特位为该K个比特中的低3个比特，如图7所示，该DMRS序列可以用于确定该扩展SSB索引的5个比特中的低3个比特(B0～B2)，该第三比特域可以用于承载该扩展SSB索引的高2个比特(B3～B4)，该第二比特域用于承载N。或者，该第二比特域可以用于承载该扩展SSB索引的高2个比特(B3～B4)，该第二比特域还用于承载N。
应理解，在该实施例中，上述各个比特域的长度，以及扩展SSB索引和N所占的比特数，以及指示方式仅为示例，本申请实施例也可以通过第三比特域承载该N，或者，通过第三比特域和第二比特域共同承载扩展SSB索引的部分比特，本申请实施例并不限于此。
因此，本申请实施例中，通过规定SSB和非SSB的信道的PRB栅格对齐或者有限取值的偏移，可以节省部分ssb-SubcarrierOffset信息(对应第二比特域)用于承载扩展SSB索引和N的部分信息，进而终端设备根据根据该第二比特域获得扩展SSB索引和N的信息，从而终端设备可以根据扩展SSB索引和N的信息，确定SSB的QCL关系。
实施例3，通过第一比特域和第二比特域承载所述扩展SSB索引和N的至少部分信息。
本实施例3综合实施例1和实施例2，可以利用第一比特域和第二比特域共同承载该扩展SSB索引和N的至少部分信息。
在一个实施例中，DMRS序列可以用于确定扩展SSB索引中的K 1个比特，具体确定方式请参考前文实施例的相关描述，这里不再赘述。
该第一比特域和第二比特域中可以用于承载该该扩展SSB索引和N的K+P比特信息中的其他K+P-K 1个比特中的至少一个比特。
可选地，在一些实施例中，若该第一比特域和第二比特域的长度不足，该第三比特域也可以用于承载该K+P-K 1个比特中的至少一个比特。
在一个具体例子中，K＝5，K 1＝3，P＝2，该K 1个比特位为该K个比特中的低3个比特，如图8所示，该DMRS序列可以用于确定该扩展SSB索引的5个比特中的低3个比特(B0～B2)，该第三比特域可以用于承载该扩展SSB索引的高2个比特(B3～B4)，通过该第一比特域和第二比特域承载N，或者也可以通过第二比特域承载该高2个比特，通过第三比特域承载该N。
应理解，上述扩展SSB索引和N所占的比特数和指示方式仅为示例，本申请实施例也可以根据扩展SSB索引和N所占的比特数，结合第一比特域，第二比特域和第三比特域的长度对于上述指示方式进行灵活调整，本申请实施例并不限于此。
因此，本申请实施例中，通过利用subCarrierSpacingCommon(对应第一比特域)和ssb-SubcarrierOffset的部分或全部比特域(对应第二比特域)承载扩展SSB索引和N的部分信息，进一步增大了能够用于承载扩展SSB索引和N的信息的比特数，进而终端设备根据根据该第一比特域和该第二比特域获得扩展SSB索引和N的信息，从而终端设备可以根据扩展SSB索引和N的信息，确定SSB的QCL关系。
