在下一代无线通信系统中,例如,在新无线(NR,New Radio)系统中,网络设备(例如基站)会周期性发送同步信号/物理广播信道块(SSB,Synchronization Signal Block,或者为SS/PBCH Block),终端设备可以基于SSB进行测量和数据收发。并且,网络设备可以指示服务小区发送的SSB的时域位置以及针对同频或异频测量的待测量的SSB集合。例如,针对服务小区,可以在SIB1或专用RRC(无线资源控制,Radio Resource Control)信令(例如ServingCellConfigCommon)中发送ssb-PositionsInBurst。例如针对同频或异频测量,可以在SIB2、SIB4或专用RRC信令(例如MeasObjectNR)中发送ssb-ToMeasure。
另一方面,网络节点之间也可以交互关于发送的SSB的时域位置以及针对同频或异频测量的待测量的SSB集合的信息。例如,网络节点可以在MeasurementTimingConfiguration中发送ssb-ToMeasure,在“Served Cell Information NR”,“Served NR Cell Information”或“Served Cell Information”中发送“SSB Positions In Burst”(ssb-PositionsInBurst)。
应该注意,上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明,并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现,针对工作在非授权频段(或者说共享频段)的新无线(NR,New Radio)系统(NR-U),SSB之间的准共址(quasi-colocation,QCL)关系是可配的,而SSB之间的QCL关系与测量和数据收发密切相关。例如,需要根据SSB之间的QCL关 系确定用于测量和数据收发的波束相关参数等。再例如,交互关于发送的SSB的时域位置以及针对同频或异频测量的待测量的SSB集合的信息(例如“SSB Positions In Burst”(ssb-PositionsInBurst),ssb-ToMeasure)也依赖于SSB之间的QCL关系。
然而,目前网络节点之间无法交互用于指示SSB之间的QCL关系的信息,这可能影响网络节点之间数据收发的协调以及测量配置,并且可能导致网络节点之间无法交互关于发送的SSB的时域位置以及针对同频或异频测量的待测量的SSB集合的信息。
针对上述问题的至少之一,本申请实施例提供一种信息交互方法和装置。
根据本申请实施例的一个方面,提供一种信息交互方法,所述方法包括:
第一节点向第二节点发送第一消息,所述第一消息包括第一指示信息和/或第二指示信息,所述第一指示信息和所述第二指示信息分别用于指示同步信号/物理广播信道块(SS/PBCH block,SSB)之间的准共址(QCL)关系。

发送单元,其向第二节点发送第一消息,所述第一消息包括第一指示信息和/或第二指示信息,所述第一指示信息和所述第二指示信息分别用于指示同步信号/物理广播信道块(SS/PBCH block,SSB)之间的准共址(QCL)关系。
根据本申请实施例的另一个方面,提供一种信息交互方法,所述方法包括:
第二节点接收第一节点发送的第一消息,所述第一消息包括第一指示信息和/或第二指示信息,所述第一指示信息和所述第二指示信息分别用于指示SSB之间的QCL关系。

接收单元,其接收第一节点发送的第一消息,所述第一消息包括第一指示信息和/或第二指示信息,所述第一指示信息和所述第二指示信息分别用于指示SSB之间的QCL关系。
本申请实施例的有益效果之一在于:通过在两个网络节点(第一节点和第二节点)之间交互用于指示SSB之间的QCL关系的信息,使得网络节点之间能够交互关于发送的SSB的时域位置以及针对同频或异频测量的待测量的SSB集合的信息,保证了 网络节点之间数据收发的协调以及测量配置。

第一方面的实施例
本申请实施例提供一种信息交互方法。

根据本申请实施例,第一节点将用于指示SSB之间的QCL关系的信息(第一指示信息和/或第二指示信息)发送给第二节点,通过交互该信息,第二节点能够得到关于发送的SSB的时域位置以及针对同频或异频测量的待测量的SSB集合的信息,保证了网络节点之间数据收发的协调以及测量配置。
下面对第一指示信息进行说明。
在一些实施例中,第一指示信息用于指示第一参数的值,该第一参数的值表明了SSB之间的QCL关系,第二节点可以根据该第一参数的值确定SSB之间的QCL关 系。该第一参数即为前述“Q”,Q的值是可配的。
在上述实施例中,该第一参数的值的取值范围可以是1,2,4,8,也即,该第一参数可以为1或2或4或8。
在一些实施例中,第一指示信息例如为ssb-PositionQCL和/或ssb-PositionQCL-Common。
在标准中,ssb-PositionQCL可以表示为如下:
在标准中,ssb-PositionQCL-Common可以表示为如下:
在“ssb-PositionQCL”和“ssb-PositionQCL-Common”中,分别包含信息元“SSB-PositionQCL-Relation”,在标准中,可以表示为如下:
其中,值n1对应1,值n2对应2,以此类推。
在一些实施例中,第一指示信息是小区特定的,也即,一个第一指示信息对应一个小区,该小区可能是该第一节点的服务小区(served cell),也可能是该第一节点的服务小区(served cell)的邻小区,本申请对此不做限制。
在一些实施例中,第一指示信息可以包含在信息元“Served NR Cell Information”中,或者包含在信息元“Served Cell Information NR”中,或者包含在信息元“Served Cell Information”中,或者包含在信息元“NR Neighbour Information”中,或者包含在信息元“Neighbour Information NR”中。不同组合的第一节点和第二节点在交互第一指示信息时可以将第一指示信息包括在上述不同的信息元中。
在上述实施例中,上述信息元“Served NR Cell Information”或“Served Cell Information NR”或“Served Cell Information”或“NR Neighbour Information”或“Neighbour Information NR”还可以包括一个小区的小区标识,例如该小区的新无线小区全局标识(New Radio Cell Global Identifier,NR CGI),该小区即为该信息元所对应的小区。若该信息元包括第一指示信息,则该小区也是该第一指示信息对应的小 区。
在一些实施例中,上述信息元“Served NR Cell Information”或“Served Cell Information NR”或“Served Cell Information”或“NR Neighbour Information”或“Neighbour Information NR”还可以包括第三指示信息,该第三指示信息用于指示一个时间窗中发送的或可能发送的SSB的时域位置,或者说该第三指示信息用于指示一个时间窗中发送的或可能发送的SSB,由此,第二节点可以根据第一指示信息确定该第三指示信息指示的位置。例如,第二节点根据第一指示信息确定SSB索引或者说SSB与SSB索引的对应关系或者说SSB之间的QCL关系,进而确定第三指示信息指示的位置。
在上述实施例中,一个时间窗中发送的或可能发送的SSB的时域位置是指一个时间窗中发送的或可能发送的SSB的候选SSB索引(candidate SSB index),其中,candidate SSB index用于表征SSB在一个时间窗中的时域位置。
在上述实施例中,一个时间窗例如为一个包括SSB(s)的半帧(half frame)或发现突发传输窗口(discovery burst transmission window),但本申请不限于此。
在上述实施例中,第三指示信息例如为SSB Positions In Burst或者ssb-PositionsInBurst。但本申请不限于此。
在上述实施例中,第三指示信息基于位图和SSB索引之间的一对一映射,指示一个时间窗中发送的或可能发送的SSB的时域位置。例如,第三指示信息中的第k个比特对应SSB index k-1的SSB。例如,第一个或最左边的比特对应SSB索引0,第二个比特对应SSB索引1,以此类推。但本申请不限于此。
例如,假设第一指示信息指示的第一参数(Q)的值为4,根据第一指示信息,可以确定SSB分别对应的SSB index。例如,如图3所示,假设第三指示信息为11000000,则在一个时间窗中发送的或可能发送的SSB包括SSB index=0和SSB index=1的SSB,不包括SSB index=2和SSB index=3的SSB。
在上述实施例中,针对授权频段,第三指示信息用于指示一个时间窗中发送的SSB的时域位置;针对非授权频段(共享频段),第三指示信息用于指示一个时间窗中可能发送的SSB的时域位置。但本申请不限于此。
在上述实施例中,第三指示信息的比特值受限于第一指示信息所指示的值。例如,如果配置了ssb-PositionQCL(第一指示信息),则ssb-PositionsInBurst(第三指示信 息)的第k位设置为0,其中k>ssb-PositionQCL。但本申请不限于此。例如,假设第一指示信息指示的第一参数(Q)的值为4,第三指示信息为8比特的位图(bitmap),则第三指示信息中的第5~8位比特的值应设置为0。
在一些实施例中,第一指示信息所对应的小区可以工作于非授权频段(或者称为共享频段),也即,第一节点可以在对应工作于非授权频段的小区的信息元中与第二节点交互上述第一指示信息,由此,第二节点根据该第一指示信息可以确定SSB之间的QCL关系。
在一些实施例中,第一指示信息所对应的小区可以工作于非授权频段,上述信息元“Served NR Cell Information”或“Served Cell Information NR”或“Served Cell Information”或“NR Neighbour Information”或“Neighbour Information NR”还可以包括上述第三指示信息,也即,第一节点可以在对应工作于非授权频段的小区的信息元中与第二节点交互上述第一指示信息和上述第三指示信息,由此,第二节点可以根据该第一指示信息确定第三指示信息指示的位置。
在一些实施例中,第一指示信息所对应的小区也可以工作于授权频段,也即,第一节点可以在对应工作于授权频段的小区的信息元中与第二节点交互上述第一指示信息,此时,第二节点可以忽略该第一指示信息。
在一些实施例中,第一指示信息所对应的小区也可以工作于授权频段,上述信息元“Served NR Cell Information”或“Served Cell Information NR”或“Served Cell Information”或“NR Neighbour Information”或“Neighbour Information NR”还可以包括上述第三指示信息,也即,第一节点可以在对应工作于授权频段的小区的信息元中与第二节点交互上述第一指示信息和上述第三指示信息,此时,第二节点可以忽略该第一指示信息。
在本申请实施例中,第一指示信息是可选的(Optional),或必要的(Mandatory),或者在一定条件下是必要的,或者在一定条件下是可选的。
例如,在一个小区在非授权频段的情况下,或者使用共享频谱信道接入工作(operates with shared spectrum channel access)的情况下,在“Served Cell Information NR”中包括“SSB Positions In Burst”的情况下,若“Served Cell Information NR”中不包括该小区对应的第一指示信息,则第二节点例如根据预定义的方法(例如,假设第一参数的取值为8)确定SSB Positions In Burst。也即,该第一指示信息是可选的。
再例如,在一个小区在授权频段的情况下,或者不使用共享频谱信道接入工作(operates without shared spectrum channel access)的情况下,在“Served Cell Information NR”中包括“SSB Positions In Burst”的情况下,第二节点忽略该小区对应的第一指示信息。也即,该第一指示信息是可选的。
再例如,在一个小区在授权频段的情况下,或者不使用共享频谱信道接入工作(operates without shared spectrum channel access)的情况下,第二节点忽略该小区对应的第一指示信息。也即,该第一指示信息是必要的。
再例如,在一个小区在非授权频段的情况下,或者使用共享频谱信道接入工作(operates with shared spectrum channel access)的情况下,在该小区的“Served Cell Information NR”中包括“SSB Positions In Burst”的情况下,“Served Cell Information NR”必须包括第一指示信息。反过来说,若“Served Cell Information NR”不包括第一指示信息,则也不能包括“SSB Positions In Burst”。即,“SSB Positions In Burst”是一定条件下可选的。也即,该第一指示信息在一定条件下是必要的。
再例如,在一个小区在非授权频段的情况下,或者使用共享频谱信道接入工作(operates with shared spectrum channel access)的情况下,在该小区的“Served Cell Information NR”必须包括第一指示信息。也即,该第一指示信息在一定条件下是必要的。
再例如,在一个小区在非授权频段的情况下,或者使用共享频谱信道接入工作(operates with shared spectrum channel access)的情况下,在该小区的“Served Cell Information NR”可以包括第一指示信息。也即,该第一指示信息在一定条件下是可选的。
再例如,在一个小区在授权频段的情况下,或者不使用共享频谱信道接入工作(operates without shared spectrum channel access)的情况下,在该小区的“Served Cell Information NR”不可以包括第一指示信息。也即,该第一指示信息在一定条件下是可选的。
下面对第一指示信息进行举例说明。
在这个示例中,假设第一指示信息包含于信息元“Served Cell Information NR”中。该信息元“Served Cell Information NR”包含相邻NG-RAN节点可能需要的用于Xn AP接口的NR小区的小区配置信息,该小区配置信息中包含上述第一指示信息 “SSB Position QCL”以及第三指示信息“SSB Positions In Burst”。在这个示例中,这两个指示信息都是可选的,即“O”。
下面的表格示出了信息元“Served Cell Information NR”的一个示例。
以上仅通过举例对第一指示信息进行了说明,本申请不限于此,第一指示信息也可以包含于其他信息元,如前所述,此处省略说明。
下面对第二指示信息进行说明。
在一些实施例中,第二指示信息用于指示第二参数的值,该第二参数的值表明了 SSB之间的QCL关系,第二节点可以根据该第二参数的值确定SSB之间的QCL关系。该第二参数即为前述“Q”,Q的值是可配的。
在上述实施例中,该第二参数的值的取值范围可以是1,2,4,8,也即,该第二参数可以为1或2或4或8。
关于该第二参数的含义,与第一参数相同,此处省略说明。
在一些实施例中,第二指示信息例如为ssb-PositionQCL和/或ssb-PositionQCL-Common。关于该第二指示信息的内容和指示方式,与第一指示信息相同,此处省略说明。
在一些实施例中,第二指示信息是小区特定的或频率特定的或测量定时(MeasTiming)配置特定的或SSB特定的,也即,一个第二指示信息对应一个小区或一个频率或一个测量定时配置或一个SSB。该小区可能是该第一节点的服务小区(served cell),也可能是该第一节点的服务小区(served cell)的邻小区,本申请对此不做限制。
在一些实施例中,第二指示信息可以包含在信息元“Served NR Cell Information”中,或者包含在信息元“Served Cell Information NR”中,或者包含在信息元“Served Cell Information”中,或者包含在信息元“Neighbour Information NR”中。不同组合的第一节点和第二节点在交互第二指示信息时可能将第二指示信息包括在上述不同的信息元中。例如,第二指示信息可以包含在上述信息元的MeasurementTimingConfiguration中的MeasTiming中,本申请对此不做限制。
在上述实施例中,上述信息元“Served NR Cell Information”或“Served Cell Information NR”或“Served Cell Information”或“Neighbour Information NR”还可以包括一个小区的小区标识,例如该小区的新无线小区全局标识(New Radio Cell Global Identifier,NR CGI),该小区即为该信息元所对应的小区。若该信息元包括第二指示信息,则该小区也是该第二指示信息对应的小区。
以第二指示信息包含于上述信息元的MeasurementTimingConfiguration中的MeasTiming中为例。
在一些实施例中,该MeasTiming中还可以包括用于指示SSB的中心频点信息,例如carrierFreq,还可以包括用于指示SSB的SCS的信息,例如ssbSubcarrierSpacing,还可以包括用于指示用于搜索SSB的SMTC,例如 ssb-MeasurementTimingConfiguration。上述SSB即为上述信息元所对应的小区的SSB或者与上述信息元所对应的小区的SSB处于相同载波的其他SSB或者上述信息元所对应的小区所在的载波的其他SSB。
图4是一个载波中的多个SSB的示意图,如图4所示,多个SSB位于不同的频率位置,标识了两个不同的小区,即NCGI=5的小区和NCGI=6的小区,其中,NCGI=5的小区与SSB1相关联,NCGI=6的小区和SSB3相关联,SSB1,SSB2,SSB3和SSB4均可以用于测量。
在一些实施例中,上述信息元“Served NR Cell Information”或“Served Cell Information NR”或“Served Cell Information”或“NR Neighbour Information”或“Neighbour Information NR”还可以包括第四指示信息,该第四指示信息用于指示在SMTC测量持续时间内要测量的SSB集合,由此,第二节点可以根据第二指示信息确定该第四指示信息指示的SSB集合。例如,第二节点根据第二指示信息确定SSB索引或者说SSB与SSB索引的对应关系或者说SSB之间的QCL关系,进而确定第四指示信息指示的SSB集合。
在上述实施例中,第四指示信息例如为ssb-ToMeasure。但本申请不限于此。
在上述实施例中,第四指示信息基于位图和SSB索引之间的一对一映射,指示在SMTC测量持续时间内要测量的SSB集合。例如,第四指示信息中的第k个比特对应SSB index k-1的SSB。例如,第一个或最左边的比特对应SSB索引0,第二个比特对应SSB索引1,以此类推。但本申请不限于此。
例如,假设第二指示信息指示的第二参数(Q)的值为4,根据第二指示信息,可以确定SSB分别对应的SSB索引。仍以图3为例,假设第四指示信息为11000000,则在SMTC测量持续时间内要测量的SSB集合包括SSB index=0和SSB index=1的SSB,不包括SSB index=2和SSB index=3的SSB。
在上述实施例中,第四指示信息的比特值受限于第二指示信息所指示的值。例如,如果配置了ssb-PositionQCL-common(第二指示信息),则ssb-ToMeasure(第四指示信息)的第k位设置为0,其中k>ssb-PositionQCL-common。但本申请不限于此,例如,假设第二指示信息指示的值为4,第四指示信息为8比特的位图,则第四指示信息中的第5~8位比特的值应设置为0。
在一些实施例中,第二指示信息所对应的小区可以工作于非授权频段(或者称为 共享频段),也即,第一节点可以在对应工作于非授权频段的小区的信息元中与第二节点交互上述第二指示信息,由此,第二节点根据该第二指示信息可以确定SSB之间的QCL关系。

在一些实施例中,第二指示信息所对应的小区也可以工作于授权频段,上述信息元“Served NR Cell Information”或“Served Cell Information NR”或“Served Cell Information”或“NR Neighbour Information”或“Neighbour Information NR”还可以包括上述第四指示信息,也即,第一节点可以在对应工作于授权频段的小区的信息元中与第二节点交互上述第二指示信息和上述第四指示信息,此时,第二节点可以忽略该第二指示信息。
在本申请实施例中,第二指示信息是可选的(Optional),或必要的(Mandatory),或者在一定条件下是必要的,或者在一定条件下是可选的。
例如,在一个小区在非授权频段的情况下,或者使用共享频谱信道接入工作(operates with shared spectrum channel access)的情况下,在该小区对应的信息元中的MeasTiming中包括“ssb-ToMeasure”的情况下,若该MeasTiming中不包括第二指示信息,则第二节点例如根据预定义的方法(例如,假设第二参数的取值为8)确定ssb-ToMeasure及其所指示的SSB集合。也即,该第二指示信息是可选的。
再例如,在一个小区在授权频段的情况下,或者不使用共享频谱信道接入工作(operates without shared spectrum channel access)的情况下,在该小区对应的信息元中的MeasTiming中包括“ssb-ToMeasure”的情况下,第二节点忽略该小区对应的第二指示信息。也即,该第二指示信息是可选的。
再例如,在一个小区在授权频段的情况下,或者不使用共享频谱信道接入工作(operates without shared spectrum channel access)的情况下,第二节点忽略该小区对应的第二指示信息。也即,该第二指示信息是必要的。

再例如,在一个小区在非授权频段的情况下,或者使用共享频谱信道接入工作(operates with shared spectrum channel access)的情况下,在该小区的对应的信息元中的“MeasTiming”必须包括第二指示信息。也即,该第二指示信息在一定条件下是必要的。
再例如,在一个小区在非授权频段的情况下,或者使用共享频谱信道接入工作(operates with shared spectrum channel access)的情况下,在该小区对应的信息元中的MeasTiming可以包括第二指示信息。也即,该第二指示信息在一定条件下是可选的。
