Description

一种无线通信系统同步块发送指示方法和设备
本申请要求于2021年12月03日提交中国国家知识产权局、申请号为202111470640.5、发明名称为“一种无线通信系统同步块发送指示方法和设备”的中国专利申请的优先权，该在先申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，尤其涉及一种无线通信系统同步块发送指示方法和设备。
背景技术
NR系统同步广播块集合(SSB)是一定时间周期内的多个同步广播块的集合，在统一周期内每个同步广播块对应一个波束方向，且一个SSB内的各个同步广播块的波束方向覆盖了整个小区。终端设备UE要从PBCH块中获取当前SSB块索引信息，才能得到空口的完整下行定时。
终端在成功检测主辅同步信号后，开始接收广播信道，广播信道中的SSB索引，用于指示SSB子载波偏移。NR PBCH DM RS除了用于信道估计外，还指示SSB索引，有助于减少PBCH的比特数。
中间节点的空间信号整形功能建立在控制电磁波在通信信道中的传播以提高通信系统性能的基础上。例如，智能超表面(RIS)是一个由大量微小元素组成的元表面，这些元素以可控的方式漫反射入射信号。智能超表面应用在通信系统中，对通信系统增加了具有实时可重构性和控制的要求。具体地是通过基站来控制超表面的相位等参数，来更好的控制漫反射入射信号实现电磁波在通信信道中的可控传播，以提高通信系统的覆盖、容量和能效等方面的性能。
由于控制如智能超表面这样的中间节点是新引入通信系统中的实体，来自基站的波束经过超表面会带来波束方向的改变，超表面可以实现多个相位变化的可控传播，已有的基站发送的SSB波束经过RIS单元后，会反射出多个波束赋形，为方便终端检测接收信号强度获得最优波束方向，同步块的发送周期和发送图样均需要重新设计。

具体实施方式
以下结合附图，详细说明本申请各实施例提供的技术方案。
本申请提出一种无线通信系统同步块发送指示方法，所述无线通信系统中包含网络设备、中间节点装置和用户设备；所述网络设备发出的业务信号经中间节点装置反射至用户设备，或，所述网络设备发出的业务信号直接被用户设备接收。SSB是一定时间周期内的多个同步广播块的集合，在统一周期内每个同步广播块对应一个波束方向，且一个SSB内的各个同步广播块的波束方向覆盖了整个小区。所述中间节点设备具有R个调整系数，网络设备的任意1个基础波束经过所述中间节点设备后，形成R个调整波束；1个基础波束和R个调整波束分别对应于1个SSB基础周期，第r+1(其中r＝1～R)个SSB基础周期对应于所述中间节点设备的第r个调整系数标识。所述调整系数为中间节点对网络设备或者终端设备的相位、幅度、极化等调整的具体数值，将所述调整系数进行身份标识，即为所述的调整系数标识。
实施例1、
网络设备控制无线通信节点子阵列的R个调整系数，网络设备的L个基础波束组成的基础波束集合经过无线通信节点转发后，形成M＝L×R个调整波束组成的调整波束集合，网络设备的同步广播块(SSB)的发送周期T为5ms的R+1倍。第r(r＝1，2,...,R)个SSB基础周期的发送，对应于第r个中间节点的调整系数。
以15kHz子载波间隔，3GHz以下频段和3-6GHz为例，NR的SSB的发送如图1，现有技术的SSB发送时间配置。
优选地，所述基础波束发送基础周期为5ms。例如，NR系统支持6种同步信号周期，即5ms、10ms、20ms、40ms、80ms、160ms。在小区搜索过程中，终端假定同步信号的周期为20ms。在NR系统中，一个SSB集合被限制在某个5ms的半帧内，且从这个半帧的第一个时隙开始。
优选地，对应于每一个基础波束，基础波束和调整波束共R+1个波束上SSB的发送周期，是基础周期的R+1倍；所述基础周期，是无中间节点装置条件下的SSB的发送周期。
图2为SSB发送周期变化的实施例。举例来说，以15kHz子载波间隔， 3GHz以下频段和3-6GHz为例，引入中间节点，可调节的调整系数R＝2，则新设计的SSB的发送如图所示，SSB的发送周期变为5ms×(R+1)＝15ms。
进一步地，有中间节点设备条件下SSB索引的数量为无中间节点设备条件下SSB索引数量的R+1倍；SSB索引的比特数为3+log 2(R×L)，其中，L为所述基础周期内的基础波束数量。
例如，NR R15支持5种SSB集合图样，这些图样与当前系统工作的频带有关：
Case A-SSB块为15kHz子载波间隔，0-3GHz，5ms周期内最大发送次数L＝4，3GHz-6GHz，最大发送次数L＝8。Case B-SSB块为30kHz子载波间隔，0-3GHz，5ms周期内最大发送次数L＝4，3GHz到6GHz，最大发送次数L＝8。Case C-SSB块为30kHz子载波间隔，对于FDD分为0-3GHz，3GHz到6GHZ两种情况，对于TDD，分为0-2.4GHz，2.4-6GHz两种情况，其中低频段5ms周期内最大发送次数L＝4，高频段最大发送次数L＝8。Case D-SSB块为120kHz子载波间隔，针对6GHz以上频率，5ms周期内最大发送次数L＝64。Case E-SSB块为240kHz子载波间隔，针对6GHZ以上频率，5ms周期内最大发送次数L＝64。对于5种case，SSB周期内发送的最大个数L＝4/8/64,每个SSB的索引从0到L-1，UE要从PBCH块中获取当前SSB块索引信息，才能得到空口的完整下行定时。
本申请扩展基础SSB的发送个数为(R+1)×L个，3GHz的情况下，扩展基础SSB的发送个数为12个，SSB索引可以标识为SSB0，SSB1，SSB2，SSB3，…，SSB11。
实施例2、
进一步地，第r+1个SSB发送的DM-RS序列初始化扰码是第r个调整系数标识的函数，且所述函数值随所述调整系数标识的值变化。
PBCH DM RS序列初始化引入RIS调整系数标识ID(RID)，用于区分不同调整系数所对应的PBCH的DM RS序列发送。
举例来说，以15kHz子载波间隔，3GHz以下频段和3-6GHz为例，引入中间节点，可调节的调整系数数量R＝2，则新设计的SSB的发送如下图所示，SSB的基础周期变为5ms×(R+1)＝15ms，扩展基础SSB的发送个数为(R+1) ×L个，3GHz的情况下，扩展基础SSB的发送个数为12个，SSB索引可以标识为SSB0_0，SSB0_1，SSB0_2，SSB0_3，SSB1_0，SSB1_1，SSB1_2，SSB1_3，SSB2_0，SSB2_1，SSB2_2，SSB2_3，也就是调整系数的索引(RID)结合每个调整系数对应的SSB块索引(SSB_index)。
用于SSB块的DM RS序列为gold序列

序列生成的初始化加入RIS调节标识
Figure PCTCN2022070474-appb-000002
这里当L＝4时，
Figure PCTCN2022070474-appb-000003
UE通过检查DM RS可获得SSB低3位的索引信息，可以同时获得半无线帧标识(指示PBCH是在帧的前半个子帧发送还是后半个子帧发送)，当L>4的时候
Figure PCTCN2022070474-appb-000004
UE将通过检查检测的PBCH DM RS获得低3位比特的SSB索引。
通过PBCH DM RS携带的一部分SSB索引信息最多为3比特，并且是SSB索引的低3位比特。在一个实施例中，NR PBCH DM RS序列是通过阶数为31的Gold序列产生随机序列，并通过QPSK调整得到所需的DM RS序列。当SSB突发集中的SSB数量L为4时，加扰序列初始化所用的参数包括PCID、半无线帧标识和SSB的索引。当每个SSB突发集中的最大SSB数量L为64时，加扰序列初始化所用的参数包括PCID和SSB索引的3个LSB(低比特位)。当L＝4或8时，UE通过检查DM RS可获得SSB的3个低比特位索引信息，甚至可以同时获得半无线帧标识。当L＝64时，UE将通过检测PBCH DM RS获得SSB索引的3个LSB。
通过增加RID相关的函数f(RID)，可以抑制不同RIS调整系数发送SSB块之间的干扰，终端在检测的时候能够区分出所对应的RIS调整系数(RID)，每个对应调整系数RID的SSB块的DM RS的初始化函数加入RID的函数f(RID)。推荐的f(RID)＝RID，或者
Figure PCTCN2022070474-appb-000005
这里RIS调整系数(RID)，还可以包括多个不同的RIS实体，用RIS ID标识，每个RIS实体对应的RIS ID有不同的调整系数，这时的RIS调整系数 是所有RIS实体对应调整系数的和。
终端通过盲检PBCH DM RS可以识别出所对应的波束是哪种调整系数(RID)，同时识别出低3位比特(issb)，结合广播信令的高3位比特，就可以获得SSB的索引值。这种方法不需要增加广播信令的比特数。低3位比特结高3位比特，共计6位比特，可以指示最多64个SSB索引值。
在本申请的实施例中，R的值是预设的，或者，由信令向终端设备指示的。优选地，预设的R值是所述中间节点设备调节能力的最大数值。
网络设备控制无线通信节点子阵列的R个调整系数，网络设备的L个基础波束组成的基础波束集合经过无线通信节点转发后，形成M＝L×R个调整波束组成的调整波束集合，增加广播信道的SSB索引的比特数到3+log 2(R×L)比特，其中R的数值为系统中中间节点调节能力的数值。
由于中间节点的引入，SSB索引的数量由L个增加到(R+1)×L个，所以SSB索引的比特数也要增加到3+log 2(R×L)比特。低位的3比特，终端在没有开启RIS情况，仍然指示已有的SSB索引，而新增加的log 2(R×L)比特用于指示新增加的SSB索引。
图3为本申请的方法用于网络设备的实施例流程图。
本申请第一方面任意一项实施例所述方法，用于网络设备，包含以下步骤201～204：
步骤201、确定中间节点调整系数的数量R。
可选的，R的数值由基站指示给终端。
可选的，R＝R max的数值为预定义的，根据系统中中间节点的调节能力和多面板的数量，定义一个最大数值。
步骤202、根据R、L确定SSB的发送基础周期、SSB索引的比特数。
确定R+1个波束上全部SSB的发送周期，是基础周期的R+1倍。所述基础周期，是无中间节点装置条件下的基础波束SSB的发送周期。
SSB索引的比特数为3+log 2(R×L)。
步骤203、通过基础波束发出R+1个SSB信号。
网络设备的任意1个基础波束经过所述中间节点设备后，形成R个调整波束；1个基础波束和R个调整波束分别对应于1个SSB基础周期，第r+1(其中r＝1～R)个SSB基础周期对应于第r个调整系数标识。
所述网络设备发送SSB时实施DM-RS序列初始化扰码，第r+1个SSB发送的DM-RS序列初始化扰码是第r个调整系数标识的函数，且所述函数值随所述调整系数标识的值变化。
步骤204、接收SSB响应信号，根据SSB响应信号对应的调整系数标识和/或SSB索引，确定响应信号占用的调整波束方向。
在步骤204中，网络设备根据终端上报的SSB最优波束信息，相应的调节中间节点的调整系数，发送最优SSB的波束。
图4为本申请的方法用于终端设备的实施例流程图。
本申请第一方面任意一项实施例所述方法，用于终端设备，包含以下步骤301～304：
步骤301、所述终端设备根据数值R、L，确定SSB的发送周期和/或SSB索引的数量。
步骤302、接收SSB信号，根据所述SSB信号对应的调整系数标识和/或SSB索引，确定SSB信号占用的调整波束方向。
由于，第r+1个SSB基础周期发送的DM-RS序列初始化扰码是第r个调整系数标识的函数，且所述函数值随所述调整系数标识的值变化。根据设定的函数确定DM-RS序列初始化扰码，终端通过盲检PBCH DM RS可以识别出所对应的波束是来自哪个调整系数(RID)。
步骤303、调整系数的索引(RID)结合每个调整系数对应的SSB块索引(SSB_index)，得到调整波束方向对应的SSB索引。
终端设备识别出低3位比特(issb)，低比特位是通过盲检PBCH DMRS获得的，结合广播信令的高3位比特，高比特位是广播信令指示的，就可以获得SSB的索引值。终端设备从PBCH块中获取当前SSB块索引信息，得到空口的完整下行定时。
步骤304、发送SSB响应信号，所述SSB响应信号对应于调整波束方向对应的SSB索引所表示的接入时机。
需要说明的是：
终端盲检SSB块的DM RS获取SSB索引低3比特位，再解码PBCH广播信令获取高log 2(R×L)比特位。
终端盲检SSB块的DM RS获取SSB索引低3比特位，以及所对应的调 整系数标识，再解码PBCH广播信令获取高3比特位。
以上两种方法都可以获取到中间设备的调整系数，以及SSB的最优波束信息。
