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)、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)通信系统或5G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。
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。
在NR系统中,当终端设备检测到的第一SSB不关联SIB1时,终端设备需要继续检测关联SIB1的第二SSB以获得SIB1。在一些实现方式中,当第一SSB不关联SIB1时,网络设备可以通过该第一SSB的PBCH中的ssb-SubcarrierOffset信息域(k SSB)中的保留值指示该第一SSB不关联SIB1,通过k SSB和pdcch-ConfigSIB1信息域中的比特指示关联SIB1的第二SSB的频域位置,从而终端设备可以根据该第二SSB的频域位置检测该第二SSB,以接收SIB1。
在NR系统中,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系统中,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。因为发送设备先听后说(Listen Before Talk,LBT)成功的时序位置是不可预期的。
故在NR-U系统中,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系统中,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。
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SSB位置索引(Position index)对Q取模的结果相同的SSB具有QCL关系。因此,若要获得SSB Position index之间的QCL关系,终端设备需要知道QCL参数Q,该Q为不满足QCL关系的SSB的最大个数,可选地,该Q可以为1,2,4,8。
在一些实现方式中,网络设备可以通过PBCH中的ssb-SubcarrierOffset信息域中的部分比特或pdcch-ConfigSIB1信息域中的部分比特来承载该QCL参数。
由上文描述可知,当SSB不关联SIB1时,需要通过该ssb-SubcarrierOffset信息域和pdcch-ConfigSIB1信息域承载关联SIB1的第二SSB的频域位置,这种情况下,如何进行QCL参数的指示是一项亟需解决的问题。
图3为本申请实施例提供的一种无线通信的方法200的示意性流程图。该方法200可以由图1所示的通信系统中的网络设备执行,如图3所示,该方法200可以包括如下至少部分内容:
S210,网络设备确定第一同步信号块SSB的SIB1关联指示信息,所述SIB1关联指示信息用于指示所述第一SSB是否关联SIB1;
S220,所述网络设备根据所述第一SSB是否关联SIB1,确定所述第一SSB中是否承载准共址QCL参数的指示信息和/或所述QCL参数在所述第一SSB中的指示方式;
S230,所述网络设备发送所述第一SSB。
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)。
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相关的信息包括系统帧号(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 PCTCN2019117651-appb-000001
以及来自层1的8比特信息,
Figure PCTCN2019117651-appb-000002
其中,A比特的MIB包括SFN的6比特,子载波间隔公共(subCarrierSpacingCommon)信息域的1比特,SSB子载波偏移(ssb-SubcarrierOffset)信息域的4比特,解调参考信号(Demodulation Reference Signal,DMRS)相关信息、调度系统信息块(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信息域包括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(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信息域可以对应于参数k SSB的低4位。subCarrierSpacingCommon信息域用于指示SIB1,用于初始接入的消息2/消息4(Msg.2/4),寻呼(paging)消息和广播系统消息(broadcast SI-messages)的子载波间隔。
层1的8比特信息,即
Figure PCTCN2019117651-appb-000003
中,
Figure PCTCN2019117651-appb-000004
为SFN的最低4位;
Figure PCTCN2019117651-appb-000005
为半帧指示;当L SSB=64时,
Figure PCTCN2019117651-appb-000006
为SSB index的最高3位,否则,
Figure PCTCN2019117651-appb-000007
为参数k SSB的最高位,
Figure PCTCN2019117651-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。当系统频带小于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。
可以理解,上述授权频谱上的PBCH中的各个信息域所占的比特数仅为示例,该各个信息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NR-U系统中,PBCH中也可以包括上述各个信息域,上述各个信息域的比特数可以与NR系统相同,在本申请一些实施例中,可以利用PBCH中的信息域承载QCL参数的指示信息,或者承载第二SSB的频域位置信息。
在本申请一些实施例中,所述网络设备可以采用第三指示方式指示所述QCL参数。
作为一个示例,所述第三指示方式可以为通过pdcch-ConfigSIB1信息域中的部分比特和ssb-SubcarrierOffset信息域的部分比特承载所述QCL参数的指示信息,具体所使用的比特数可以根据QCL参数的指示信息所占的比特数确定,例如,若QCL参数的指示信息占2比特,可以采用pdcch-ConfigSIB1信息域中的1比特和ssb-SubcarrierOffset信息域的1比特承载所述QCL参数的指示信息,如图6所示。
作为一个示例,所述第三指示方式可以为通过pdcch-ConfigSIB1信息域中的部分比特和subCarrierSpacingCommon信息域的部分比特承载所述QCL参数的指示信息,具体所使用的比特数可以根据QCL参数的指示信息所占的比特数确定,例如,若QCL参数的指示信息占2比特,可以采用pdcch-ConfigSIB1信息域中的1比特和subCarrierSpacingCommon信息域的1比特承载所述QCL参数的指示信息,如图4所示。
也就是说,无论所述第一SSB是否关联SIB1,该网络设备都可以通过第三指示方式指示所述QCL参数,进一步地,终端设备可以获知该QCL参数的信息,从而可以根据该QCL参数确定SSB之间的QCL关系,进而可以对满足QCL关系的SSB进行联合处理,提升系统性能。
在本申请另一些实施例中,所述网络设备可以根据所述第一SSB是否关联SIB1,确定所述第一SSB中是否承载QCL参数的指示信息。
例如,若所述第一SSB不关联SIB1,网络设备可以确定所述第一SSB不承载QCL参数的指示信息。这样,当终端设备检测到的第一SSB不关联SIB1时,该第一SSB需要指示关联SIB1的第二SSB的频域位置,该终端设备可以从该第二SSB中获取QCL参数,也就是说,从该第一SSB中获得的QCL参数并没有意义,此情况下,该第一SSB可以不承载QCL参数,从而可以节省一定的信息域用于指示第二SSB的频域位置或其他信息。
又例如,若所述第一SSB关联SIB1,网络设备可以确定所述第一SSB承载所述QCL参数的指 示信息。进一步地,所述网络设备还可以确定所述QCL参数的指示信息在所述第一SSB中的指示方式为特定的指示方式。可选地,所述特定的指示方式可以为通过所述PBCH的信息域中的部分比特承载所述QCL参数的指示信息。
作为一些示例,所述特定的指示方式为以下指示方式中的任一种:
通过PDCCH配置SIB1信息域(pdcch-ConfigSIB1)中的K个比特指示所述QCL参数,其中,所述K为正整数,其中,该K可以等于QCL参数所占的比特数;
通过PDCCH配置SIB1信息域(pdcch-ConfigSIB1)中的A个比特和SSB子载波间隔公共(subCarrierSpacingCommon)信息域中的B个比特指示所述QCL参数,所述A和所述B为正整数,其中,该A和B之和等于QCL参数所占的比特数;
通过PDCCH配置SIB1(pdcch-ConfigSIB1)信息域中的C个比特和SSB子载波偏移(ssb-SubcarrierOffset)信息域中的D个比特指示所述QCL参数,所述C和所述D为正整数,该C和D之和等于QCL参数所占的比特数;
通过SSB子载波偏移(ssb-SubcarrierOffset)信息域中的E个比特和SSB子载波间隔公共(subCarrierSpacingCommon)信息域中的F个比特指示所述QCL参数,所述E和所述F为正整数,该E和F之和等于QCL参数所占的比特数。
作为一些示例,若所述QCL参数的指示信息占2个比特,所述K为2;
所述A为1,所述B为1;
所述C为1,所述D为1;
所述E为1,所述F为1。
在其他替代实施例中,所述网络设备可以根据所述第一SSB是否关联SIB1,确定QCL参数在所述第一SSB中的指示方式。
例如,若所述第一SSB不关联SIB1,确定所述QCL参数在所述第一SSB中的指示方式为第一指示方式。
又例如,若所述第一SSB关联SIB1,确定所述QCL参数在所述第一SSB中的指示方式为第二指示方式。
作为一个示例,所述第一指示方式和所述第二指示方式相同,即所述第一指示方式和所述第二指示方式中承载所述QCL参数的指示信息所使用的比特域相同。
应理解,所述的比特域相同,可以指所使用的信息域以及所用的该信息域中的比特数相同,并不表示信息域中的每个比特的含义不同。例如,QCL参数的指示信息需要2比特,该2比特的比特域的顺序可以相同,也可以不同。
例如,所述第一指示方式是通过pdcch-ConfigSIB1信息域中的1比特和ssb-SubcarrierOffset信息域中的1比特指示,其中,pdcch-ConfigSIB1信息域中的1比特对应指示信息中的比特1,ssb-SubcarrierOffset信息域中的1比特对应指示信息中的比特0;所述第二指示方式是通过pdcch-ConfigSIB1信息域中的1比特和ssb-SubcarrierOffset信息域中的1比特指示,其中,pdcch-ConfigSIB1信息域中的1比特对应指示信息中的比特0,ssb-SubcarrierOffset信息域中的1比特对应指示信息中的比特1,此情况下,可以认为第一指示方式和所述第二指示方式相同。
作为另一示例,所述第一指示方式和所述第二指示方式不同,具体地,所述第一指示方式和所述第二指示方式中承载所述QCL参数的指示信息所使用的比特域至少部分不同。例如,所述第一指示方式是通过pdcch-ConfigSIB1信息域中的1比特和ssb-SubcarrierOffset信息域中的1比特指示,所述第二指示方式是通过pdcch-ConfigSIB1信息域中的1比特和subCarrierSpacingCommon信息域中的1比特指示,则第一指示方式和所述第二指示方式不同。
作为一些示例,所述第一指示方式为以下指示方式中的任一种:
通过PDCCH配置SIB1信息域中的K个比特指示所述QCL参数,其中,所述K为正整数;
通过PDCCH配置SIB1信息域中的A1个比特和子载波间隔公共信息域中的B1个比特指示所述QCL参数,所述A1和所述B1为正整数;
通过PDCCH配置SIB1信息域中的C1个比特和SSB子载波偏移信息域中的D1个比特指示所述QCL参数,所述C1和所述D1为正整数;
通过SSB子载波偏移信息域中的E1个比特和子载波间隔公共信息域中的F1个比特指示所述QCL参数,所述E1和所述F1为正整数。
应理解,上述所占用的各个信息域中的比特数可以根据QCL参数的指示信息所占的比特数确定,作为一些示例,若所述QCL参数的指示信息占2个比特,所述K为2;
所述A1为1,所述B1为1;
所述C1为1,所述D1为1;
所述E1为1,所述F1为1。
作为一些示例,所述第二指示方式为以下指示方式中的任一种:
通过PDCCH配置SIB1信息域中的K个比特指示所述QCL参数,其中,所述K为正整数;
通过PDCCH配置SIB1信息域中的A2个比特和子载波间隔公共信息域中的B2个比特指示所述QCL参数,所述A和所述B为正整数;
通过PDCCH配置SIB1信息域中的C2个比特和SSB子载波偏移信息域中的D2个比特指示所述QCL参数,所述C2和所述D2为正整数;
通过SSB子载波偏移信息域中的E2个比特和子载波间隔公共信息域中的F2个比特指示所述QCL参数,所述E2和所述F2为正整数。
应理解,上述所占用的各个信息域中的比特数可以根据QCL参数的指示信息所占的比特数确定,作为一些示例,若所述QCL参数的指示信息占2个比特,所述K为2;
所述A2为1,所述B2为1;
所述C2为1,所述D2为1;
所述E2为1,所述F2为1。
进一步地,在一些实施例中,若所述第一SSB不关联SIB1,所述第一SSB还包括第二SSB的频域位置的指示信息,其中,所述第二SSB关联SIB1。
例如,可以通过所述第一SSB的PBCH中的不用于承载QCL参数的指示信息的信息域指示所述第二SSB的频域位置,比如,通过SSB子载波偏移信息域中的N个比特和PDCCH配置SIB1信息域中的M个比特指示所述第二SSB的频域位置,所述N和所述M为正整数,或者也可以通过PBCH中的其他未使用的信息域中的部分或全部比特指示所述第二SSB的频域位置,本申请实施例对此不作限定。
以上,仅以通过所述PBCH中的pdcch-ConfigSIB1信息域、ssb-SubcarrierOffset信息域和subCarrierSpacingCommon信息域中的部分比特指示所述QCL参数为例进行说明,但本申请并不限于此,在其他替代实施例中,也可以利用PBCH中的其他信息域指示该QCL参数,例如,在一些实施例中,所述网络设备可以通过pdcch-ConfigSIB1信息域和ssb-SubcarrierOffset信息域之外的其他信息域指示所述QCL参数。
在一些实施例中,所述其他信息域包括以下信息域之中的至少一个:
subCarrierSpacingCommon信息域;
系统帧号(System Frame Number,SFN)信息域;
解调参考信号相关信息域;
小区禁止(cellBarred)信息域;
同频小区重选信息域;
空闲比特域。
作为一些示例,若所述QCL参数的指示信息占用2比特,可以通过子载波间隔公共信息域中的1比特和SFN信息域中的1比特指示所述QCL参数,或者也可以通过cellBarred信息域中的2比特指示所述QCL参数,或者通过同频小区重选信息域中的2比特指示所述QCL参数等。
特别地,当第一SSB不关联SIB1时,所述网络设备通过所述其他信息域指示所述QCL参数。
可以理解,当第一SSB不关联SIB1时,第一SSB中需要承载第二SSB的频域位置的指示信息,通过PBCH中除pdcch-ConfigSIB1信息域和ssb-SubcarrierOffset信息域之外的其他信息域指示所述QCL参数,这样,现有的pdcch-ConfigSIB1信息域和ssb-SubcarrierOffset信息域的含义不变,对现有技术的影响较小。并且在第一SSB不关联SIB1时,上述其他信息域中承载的信息实际上是没有意义的,此情况下利用这些信息域承载QCL参数的指示信息,有利于提升系统资源利用率,进而提升系统性能。
以下,结合实施例1和实施例2,以通过所述PBCH中的pdcch-ConfigSIB1信息域、ssb-SubcarrierOffset信息域和subCarrierSpacingCommon信息域中的部分比特指示所述QCL参数为例进行说明,但本申请实施例并不限于此。
实施例1:
所述网络设备根据所述第一SSB是否关联SIB1,确定所述第一SSB中是否承载QCL参数的指示信息。
在本申请实施例中,所述SIB1关联指示信息可以承载在PBCH中,例如,PBCH的ssb-SubcarrierOffset信息域中,用于指示所述第一SSB是否关联SIB1或类型0PDCCH公共搜索空间 (Type0-PDCCH common search spach)。
情况1:所述SIB1关联指示信息指示该第一SSB不关联SIB1,所述网络设备可以确定所述第一SSB不承载QCL参数的指示信息,这种情况下,所述第一SSB中可以包括第二SSB的频域位置的指示信息,例如,通过ssb-SubcarrierOffset信息域和pdcch-ConfigSIB1信息域中的部分或全部比特指示所述第二SSB的频域位置信息。
情况2:所述SIB1关联指示信息指示该第一SSB关联SIB1,网络设备可以通过前述的特定的指示方式指示所述QCL参数。。
因此,当终端设备检测到的第一SSB不关联SIB1时,由于需要通过PBCH中的信息域指示第二SSB的频域位置,进一步终端设备还需要继续检测第二SSB以获得QCL参数,因此在该第一SSB中获得的QCL参数并没有意义,因此,当SSB不关联SIB1时,可以不承载QCL参数的指示信息,这种情况下,可以继续通过ssb-SubcarrierOffset信息域和pdcch-ConfigSIB1信息域指示第二SSB的频域位置的指示方式,能够更好的兼容现有技术。在第一SSB关联SIB1时,终端设备可以根据该第一SSB获取QCL参数,进一步可以对满足QCL关系的SSB进行联合处理,提升系统性能。
实施例2:
所述网络设备根据所述第一SSB是否关联SIB1,确定所述QCL参数在所述第一SSB中的指示方式。
在该实施例2中,无论第一SSB是否关联SIB1,终端设备都可以根据该第一SSB获得QCL参数,进一步可以对满足QCL关系的SSB进行联合处理,在第一SSB不关联SIB1时,有利于提升第二SSB的接收性能。
具体地,若所述第一SSB不关联SIB1,确定所述第一SSB中所述QCL参数的指示方式为第一指示方式;若所述第一SSB关联SIB1,确定所述第一SSB中所述QCL参数的指示方式为第二指示方式。
其中,所述第一指示方式和所述第二指示方式的实现方式参考前文实施例的相关描述,这里不再赘述。
结合图4至图7,以QCL参数的指示信息为2比特为例,说明该第一指示方式和所述第二指示方式的具体实现,当QCL参数的指示信息为其他比特数时,可以对具体的指示方式进行调整,本申请实施例对此不作限定。
实施例2-1:
所述第一SSB不关联SIB1时,可以采用第一指示方式指示所述QCL参数,具体地,如图4所示,所述第一指示方式为通过pdcch-ConfigSIB1信息域中的1个比特和subCarrierSpacingCommon信息域中的1个比特指示所述QCL参数。
进一步地,所述第一SSB还包括第二SSB的频域位置的指示信息,作为一个示例,承载所述第二SSB的频域位置的指示信息的信息域可以包括ssb-SubcarrierOffset信息域中的5比特(bit0~bit4)和pdcch-ConfigSIB1信息域中的7比特(例如,比特0~比特6)。
作为一种例子,ssb-SubcarrierOffset取值为24-31表示该SSB不关联SIB1。
所述第一SSB关联SIB1时,可以采用第二指示方式指示所述QCL参数,具体地,如图5所示,所述第二指示方式为通过pdcch-ConfigSIB1信息域中的2个比特指示所述QCL参数。
进一步地,通过PBCH的信息域中的剩余比特承载其他信息,例如,通过pdcch-ConfigSIB1信息域中的其他6个比特指示控制资源集(Control Resource Set,COREST)和搜索空间零(searchspacezero)信息。
实施例2-2:
所述第一SSB不关联SIB1时,可以采用第一指示方式指示所述QCL参数,具体地,如图6所示,所述第一指示方式为通过pdcch-ConfigSIB1信息域中的1个比特和ssb-SubcarrierOffset信息域中的1个比特指示所述QCL参数。
进一步地,所述第一SSB还包括第二SSB的频域位置的指示信息,作为一个示例,承载所述第二SSB的频域位置的指示信息的信息域可以包括ssb-SubcarrierOffset信息域中的4比特(bit0~bit3)和pdcch-ConfigSIB1信息域中的7比特(例如,比特0~比特6)。
作为一种例子,ssb-SubcarrierOffset取值为12-15表示该SSB不关联SIB1。
所述第一SSB关联SIB1时,可以采用第二指示方式指示所述QCL参数,具体地,如图5所示,所述第二指示方式为通过pdcch-ConfigSIB1信息域中的2个比特指示所述QCL参数。
进一步地,通过PBCH的信息域中的剩余比特承载其他信息,例如,通过pdcch-ConfigSIB1信息域中的其他6个比特(例如,比特0~比特5)指示COREST和searchspacezero的信息。
实施例2-3:
所述第一SSB不关联SIB1时,可以采用第一指示方式指示所述QCL参数,具体地,如图6所示,所述第一指示方式为通过pdcch-ConfigSIB1信息域中的1个比特和ssb-SubcarrierOffset信息域中的1个比特指示所述QCL参数。
进一步地,所述第一SSB还包括第二SSB的频域位置的指示信息,作为一个示例,承载所述第二SSB的频域位置的指示信息的信息域可以包括ssb-SubcarrierOffset信息域中的4比特(bit0~bit3)和pdcch-ConfigSIB1信息域中的7比特(例如,比特0~比特6)。
作为一种例子,ssb-SubcarrierOffset取值为12-15表示该SSB不关联SIB1。
所述第一SSB关联SIB1时,可以采用第二指示方式指示所述QCL参数,具体地,如图7所示,所述第二指示方式为通过ssb-SubcarrierOffset信息域中的1个比特和subCarrierSpacingCommon信息域中的1个比特指示所述QCL参数。
进一步地,通过PBCH的信息域中的剩余比特承载其他信息,例如,通过pdcch-ConfigSIB1信息域中的8个比特(比特0~比特7)指示COREST和searchspacezero的信息,这样,NR-U系统中的pdcch-ConfigSIB1信息域的含义可以和NR系统相同。
实施例2-4:
所述第一SSB不关联SIB1时,可以采用第一指示方式指示所述QCL参数,具体地,如图7所示,所述第一指示方式为通过ssb-SubcarrierOffset信息域中的1个比特和subCarrierSpacingCommon信息域中的1个比特指示所述QCL参数。
进一步地,所述第一SSB还包括第二SSB的频域位置的指示信息,作为一个示例,承载所述第二SSB的频域位置的指示信息的信息域可以包括pdcch-ConfigSIB1信息域中的8个比特(bit0~bit7)。
作为一种例子,ssb-SubcarrierOffset取值为12-15表示该SSB不关联SIB1。
所述第一SSB关联SIB1时,可以采用第二指示方式指示所述QCL参数,具体地,如图4所示,所述第二指示方式为通过pdcch-ConfigSIB1信息域中的1个比特和subCarrierSpacingCommon信息域中的1个比特指示所述QCL参数。
进一步地,通过PBCH的信息域中的剩余比特承载其他信息,例如,通过pdcch-ConfigSIB1信息域中的剩余7个比特(如比特0~比特6)指示COREST和searchspacezero的信息。
应理解,以上实施例2-1至实施例2-4所示的指示方式仅为示例,所述第一指示方式和所述第二指示方式也可以为其他指示方式的组合,例如,所述第一指示方式为图4所示的指示方式,所述第二指示方式为图6所示的指示方式,又例如,所述第一指示方式为图5所示的指示方式,所述第二指示方式为图7所示的指示方式等,本申请实施例并不限于此。
还应理解,在本申请实施例中,信息域中的1个比特或2个比特在该信息域中的位置可以是任意位置,本申请实施例对此不作限定,pdcch-ConfigSIB1信息域中的1个比特可以为pdcch-ConfigSIB1信息域中的比特0或者比特7,或者也可以为其他比特。
并且,通过至少两个比特合并指示所述QCL参数时,该至少两个比特在指示信息中的位置不作具体限定,例如,通过pdcch-ConfigSIB1信息域中的1个比特和subCarrierSpacingCommon信息域中的1个比特指示所述QCL参数时,该pdcch-ConfigSIB1信息域中的1个比特可以为高位,或者,subCarrierSpacingCommon信息域中的1个比特可以为高位,本申请实施例对此不作限定。本申请实施例旨在说明承载该QCL参数的指示信息的信息域,以及该指示信息在该信息域中所占的比特数,对于比特位的具体顺序不作限定。
该实施例2中,网络设备可以根据SIB1关联指示信息,确定QCL参数的指示信息在PBCH中的不同指示方式(或者说,不同的承载方式),有利于保证终端设备正确的接收QCL参数的指示信息。
进一步地,在该第一SSB不关联SIB1时,终端设备仍然可以获得QCL参数的指示信息,从而在提高第二SSB的接收性能,并且网络设备根据是否SSB关联SIB1,通过不同的指示方式指示QCL参数,也可以避免第二SSB的频域位置的指示信息的信息域与QCL参数的指示信息的信息域发生重叠导致的冲突。
