PRS静默方法、装置及存储介质
相关申请的交叉引用
本申请要求于2022年08月10日提交的申请号为202210956584.4，发明名称为“PRS静默方法、装置及存储介质”的中国专利申请的优先权，其通过引用方式全部并入本文。
技术领域
本公开涉及无线通信技术领域，尤其涉及一种PRS静默方法、装置及存储介质。
背景技术
在无线通信网络中，终端/用户设备(User Equipment,UE)通过接收不同传输设备发送的定位参考信号(Positioning Reference Signal,PRS)进行位置估计。
为了降低多个发送接收点(Transmission Reception Point,TRP)在相同的时频资源上发送的PRS之间的干扰，需要设计PRS静默。新空口(New Radio,NR)协议Rel-16版本中定义了Uu口的PRS静默的整体设计，具体是基于下行链路(Down Link,DL)PRS资源集的颗粒度进行静默，即一个DL PRS资源集包含的所有DL PRS资源都将被静默。DL PRS资源被静默表示TRP不在该DL PRS资源上传输PRS。
目前在直接通信(Sidelink,SL)系统中没有PRS的配置，也没有相应的PRS静默机制，造成SL系统中UE间的PRS之间的干扰。 发明内容

为了便于更加清晰地理解本公开各实施例，首先对一些相关的技术知识进行如下介绍。
1、DL PRS资源集
一个基站gNB可有一个或多个定位参考信号的TRP。每个TRP可有一个或2个DL PRS资源集。每个DL PRS资源集是包含一个或多个DL PRS资源的一个集合，其中的每一个DL PRS资源具有一个DL PRS资源ID。
一个DL PRS资源集中的一个DL PRS资源ID与从单个TRP发送的单个波束相关联，同时，TRP可以发送一个或多个波束。
2、DL PRS资源
每个DL PRS资源配置一个Comb-N梳齿尺寸，用来在频域上将DL PRS序列映射到资源单元；
DL PRS资源至少由以下参数描述：DL PRS资源ID、序列ID、Comb Size-N梳齿尺寸、RE频偏、DL PRS资源的初始时隙和符号、每个DL PRS资源的符号数(DL PRS资源的持续时间)和与其他DL参考信号的准共站址(Quasi-Co-Location,QCL)信息。
DL PRS资源的符号数可以从集合{2,4,6}中灵活配置。
DL PRS资源comb-N梳齿尺寸可以从集合{2,4,6}中灵活配置。DL PRS资源在频域上的起始物理资源块(Physical Resource Block,PRB)位置是相对于每个频率层(frequency layer)的频率参照点(Point A)来定义的。
图1是本公开实施例提供的PRS静默方法的流程示意图之一，如图1所示，本公开实施例提供一种PRS静默方法，执行主体是终 端，例如：手机，该方法包括：
步骤101，接收比特位图，比特位图中的每一个比特对应一个资源。
具体地，终端接收网络设备或其他终端配置的比特位图(bitmap)，比特位图的数量可以是一个或多个，比特位图中的每一个比特对应一个资源，资源可以是时隙组、时隙、PRS资源集或PRS资源等。不同的比特位图对应不同的资源。
步骤102，基于比特位图，确定PRS静默的资源。
具体地，终端接收一个或多个比特位图之后，确定一个或多个比特位图中每一个比特的值，一个比特位图中比特的不同值对应不同的指示。
例如，一个比特位图中比特的值为1时，指示该比特对应的资源被静默，不能用于PRS传输；一个比特位图中比特的值为0时，指示该比特对应的资源可以允许用于PRS传输。
或者例如，一个比特位图中的一个比特的值为0时，指示该比特对应的资源被静默，不能用于PRS传输；一个比特位图中的一个比特的值为1时，指示该比特对应的资源可以允许用于PRS传输。
基于比特的值为0或1进行指示只是示例性的，本公开实施例中对指示方式不做具体限定。
终端可以基于比特位图中每一个比特的值对应的指示，确定PRS静默的资源，也即确定不能用于PRS传输的资源。
本公开实施例提供的PRS静默方法，通过接收与资源对应的比特位图，基于比特位图的指示，实现PRS静默，避免PRS之间的干扰。
在一些实施例中，比特位图包括第一比特位图；第一比特位图中的每一个比特对应一个时隙组；第一比特位图用于指示PRS静默的时隙组。
具体地，终端接收第一比特位图，第一比特位图中的一个比特对应一个时隙组，一个时隙组包含多个时隙。在第一比特位图中，比特的不同值对应不同的指示。
例如，第一比特位图中的一个比特的值为1时，指示该比特对应的时隙组被静默，不能用于PRS传输；第一比特位图中的一个比特的值为0时，指示该比特对应的时隙组可以允许用于PRS传输。
或者例如，第一比特位图中的一个比特的值为0时，指示该比特对应的时隙组被静默，不能用于PRS传输；第一比特位图中的一个比特的值为1时，指示该比特对应的时隙组可以允许用于PRS传输。
基于比特的值为0或1进行指示只是示例性的，本公开实施例中对指示方式不做具体限定。
终端可以基于第一比特位图中每一个比特的值对应的指示，确定PRS静默的时隙组。
图2是本公开实施例提供的基于第一比特位图指示PRS静默的原理示意图，如图2所示，第一比特位图中有M位比特，表示为(a0,a1,…,aM-2,aM-1)，第一比特位图中的一个比特ai,i＝0,1,…,M-1，对应一个时隙组，每个时隙组包含L个时隙。
当采用15kHz子载波间隔传输时，预定义的总时隙数为10240，从a0对应的时隙组到aM-1对应的时隙组一共包含10240个时隙。
在图2中，a1对应的时隙组和aM-2对应的时隙组都被小黑点占据，表示在第一比特位图中，a1和aM-2的值为1，其他比特的值为0，指示a1对应的时隙组和aM-2对应的时隙组被静默，不能用于PRS传输；而其余比特对应的时隙组可以用于PRS传输。
本公开实施例提供的PRS静默方法，终端通过接收与时隙组对 应的第一比特位图，基于第一比特位图的指示确定PRS静默的时隙组，进一步实现PRS静默，避免PRS之间的干扰。
在一些实施例中，第一比特位图的比特长度是基于预设总时隙数和一个时隙组中的时隙个数确定的。

第一比特位图的比特长度为时隙组的个数，时隙组的个数可以基于预设总时隙数和一个时隙组中的时隙个数进行确定，因此，第一比特位图的比特长度可以基于预设总时隙数和一个时隙组中的时隙个数进行确定。
第一比特位图的比特长度的表达式如下所示：
式中，M表示第一比特位图的比特长度，Tmax表示预设总时隙数，L表示一个时隙组中的时隙个数。
本公开实施例提供的PRS静默方法，基于预设总时隙数和一个时隙组中的时隙个数确定第一比特位图的比特长度，有利于基于第一比特位图确定PRS静默的时隙组。
在一些实施例中，比特位图包括第二比特位图；第二比特位图中的每一个比特对应一个时隙；第二比特位图用于指示PRS静默的时隙。
具体地，终端可以第二比特位图，还可以接收第一比特位图和第二比特位图。

例如，第二比特位图中的一个比特的值为1时，指示该比特对应的时隙被静默，不能用于PRS传输；第二比特位图中的一个比特的值为0时，指示该比特对应的时隙可以允许用于PRS传输。
或者例如，第二比特位图中的一个比特的值为0时，指示该比特对应的时隙被静默，不能用于PRS传输；第二比特位图中的一个比特的值为1时，指示该比特对应的时隙可以允许用于PRS传输。
基于比特的值为0或1进行指示只是示例性的，本公开实施例中对指示方式不做具体限定。
终端可以基于第二比特位图中每一个比特的值对应的指示，确定PRS静默的时隙。
图3是本公开实施例提供的基于第二比特位图指示PRS静默的原理示意图，如图3所示，第一比特位图表示为(a0,a1,…,aM-2,aM-1)，第一比特位图中的一个比特ai,i＝0,1,…,M-1，对应一个时隙组，每个时隙组包含L个时隙。a0对应的时隙组可以用于PRS传输，a0对应的时隙组包含L个时隙，分别为时隙0，时隙1，……，时隙L-2和时隙L-1。
第二比特位图中有L位比特，表示为(b0,b1,…,bL-2,bL-1)，第二比特位图中的一个比特bw,w＝0,1,…,L-1，对应一个时隙。b0对应时隙0，b1对应时隙1，……，bL-2对应时隙L-2，bL-1对应时隙L-1。
在图3中，时隙0和时隙L-1都被小黑点占据，表示在第二比特位图中，b0和bL-1的值为1，其他比特的值为0，指示b0对应的时隙0和bL-1对应的时隙L-1被静默，不能用于PRS传输；而其余比特对应的时隙可以用于PRS传输。
本公开实施例提供的PRS静默方法，终端通过接收与时隙对应的第二比特位图，基于第二比特位图的指示确定PRS静默的时隙，进一步实现PRS静默，避免PRS之间的干扰。
在一些实施例中，比特位图还包括：第三比特位图；第三比特位图中的每一个比特对应一个时隙；第三比特位图用于指示允许传输PRS的时隙。
具体地，终端可以接收第一比特位图和第三比特位图，还可以接收第一比特位图、第三比特位图和第二比特位图。
第三比特位图的比特长度可以根据第一比特位图中每个比特对应的时隙组中的时隙个数进行确定。第三比特位图中的每一个比特对应一个时隙。在第三比特位图中，比特的不同值对应不同的指示。
例如，第三比特位图中的一个比特的值为1时，指示该比特对应的时隙可以允许用于PRS传输。第三比特位图中的一个比特的值为0时，指示该比特对应的时隙被静默，不能用于PRS传输。
或者例如，第三比特位图中的一个比特的值为0时，指示该比特对应的时隙可以允许用于PRS传输。第三比特位图中的一个比特的值为1时，指示该比特对应的时隙被静默，不能用于PRS传输。
基于比特的值为0或1进行指示只是示例性的，本公开实施例中对指示方式不做具体限定。
终端可以基于第三比特位图中每一个比特的值对应的指示，确定允许传输PRS的时隙。
图4是本公开实施例提供的基于第三比特位图指示PRS传输的原理示意图，如图4所示，第一比特位图表示为(a0,a1,…,aS-2,aS-1)，第一比特位图中的一个比特aq,q＝0,1,…,S-1，对应一个时隙组，每个时隙组包含N个时隙。a0对应的时隙组可以用于PRS传输，a0对应的时隙组包含N个时隙，分别为时隙0，时隙1，……，时隙N-2和时隙N-1。
第三比特位图中有N位比特，表示为(c0,c1,…,cN-2,cN-1)，第三 比特位图中的一个比特Cn,n＝0,1,…,N-1，对应一个时隙。c0对应时隙0，c1对应时隙1，……，cN-2对应时隙N-2，cN-1对应时隙N-1。
在图4中，除时隙1和时隙N-2外，其他时隙都被横线占据，表示在第三比特位图中，除c1和cN-2的值为0外，其他比特的值为1，指示c1对应的时隙1和cN-2对应的时隙N-2被静默，不能用于PRS传输；而其余比特对应的时隙可以用于PRS传输。
本公开实施例提供的PRS静默方法，终端通过接收与时隙对应的第三比特位图，基于第三比特位图的指示确定用于PRS传输的时隙，进一步实现PRS静默，避免PRS之间的干扰。
在一些实施例中，第二比特位图的比特长度是基于第三比特位图中用于指示允许传输PRS的时隙个数确定的；或者，是基于信令配置的。
具体地，第二比特位图的比特长度可以是基于高层信令配置的。例如，配置第二比特位图的比特长度为K，K为正整数。
第二比特位图的比特长度可以是基于第三比特位图中用于指示允许传输PRS的时隙个数确定的，也就是第二比特位图的比特长度等于第三比特位图中用于指示允许传输PRS的时隙个数。
例如，第三比特位图表示为(c0,c1,…,cN-2,cN-1)，第三比特位图中的一个比特Cn,n＝0,1,…,N-1，对应一个时隙。c0对应时隙0，c1对应时隙1，……，cN-2对应时隙N-2，cN-1对应时隙N-1。c1对应的时隙1和cN-2对应的时隙N-2被静默，不能用于PRS传输；而其余比特对应的时隙可以用于PRS传输。
可见，第三比特位图对应N个时隙，其中有N-2个时隙为允许传输PRS的时隙，则第二比特位图的比特长度为N-2，其中每一个比特对应一个允许传输PRS的时隙。b0对应时隙0，b1对应时隙2，……，bN-3对应时隙N-1。
本公开实施例提供的PRS静默方法，基于第三比特位图中用于指示允许传输PRS的时隙个数确定；或者，是基于信令配置确定第二比特位图的比特长度，有利于基于第二比特位图确定PRS静默的时隙，降低静默指示的开销。

第六比特位图；第六比特位图中的每一个比特对应PRS资源集中的一个PRS资源，第六比特位图用于指示静默的PRS资源。
具体地，终端接收第四比特位图、第五比特位图和第六比特位图中的一个或多个。
第四比特位图的比特长度由高层配置。第四比特位图中的每一个比特对应预设数目个PRS周期对应的资源。预设数目个由高层配置的，记为PRS周期可以是基于PRS资源集的周期，还可以是基于PRS资源的周期。
图5是本公开实施例提供的基于第四比特位图指示PRS静默的原理示意图，如图5所示，第四比特位图的比特长度为6，配置了为2，第四比特位图中一个比特对应2个PRS周期对应的资源。
终端可以基于第四比特位图中每一个比特的值对应的指示，确定PRS周期对应的资源是否被静默。

例如，PRS资源集内有4个PRS资源，分别是PRS资源0、PRS资源1、PRS资源2和PRS资源3，则第六比特位图的比特长度为4，第六比特位图中的每一个比特对应PRS资源集中的一个PRS资源。
终端可以基于第六比特位图中每一个比特的值对应的指示，确定PRS资源是否被静默。
例如，第六比特位图中的第二个比特的值为1，表示PRS资源1被静默，不能用于PRS传输。

步骤601，向终端发送配置的比特位图，比特位图中的每一个比特对应一个资源，比特位图用于向终端指示PRS静默的资源。
具体地，电子设备配置比特位图，并向终端发送配置的比特位图。比特位图的数量可以是一个或多个，比特位图中的每一个比特对应一个资源，资源可以是时隙组、时隙、PRS资源集或PRS资源等。不同的比特位图对应不同的资源。一个比特位图中比特的不同值对应不同的指示。
例如，一个比特位图中比特的值为1时，指示该比特对应的资源被静默，不能用于PRS传输；一个比特位图中比特的值为0时，指示该比特对应的资源可以允许用于PRS传输。
或者例如，一个比特位图中的一个比特的值为0时，指示该比特对应的资源被静默，不能用于PRS传输；一个比特位图中的一个比特的值为1时，指示该比特对应的资源可以允许用于PRS传输。
基于比特的值为0或1进行指示只是示例性的，本公开实施例中对指示方式不做具体限定。
终端可以基于比特位图中每一个比特的值对应的指示，确定PRS静默的资源，也即确定不能用于PRS传输的资源。
本公开实施例提供的PRS静默方法，通过向终端发送与资源对应的比特位图，以供终端基于比特位图的指示，实现PRS静默，避免PRS之间的干扰。
在一些实施例中，比特位图包括第一比特位图；第一比特位图中的每一个比特对应一个时隙组；第一比特位图用于指示PRS静默的时隙组。
具体地，电子设备可以向终端发送配置的第一比特位图，第一比 特位图中的一个比特对应一个时隙组，一个时隙组包含多个时隙。在第一比特位图中，比特的不同值对应不同的指示。
例如，第一比特位图中的一个比特的值为1时，指示该比特对应的时隙组被静默，不能用于PRS传输；第一比特位图中的一个比特的值为0时，指示该比特对应的时隙组可以允许用于PRS传输。
或者例如，第一比特位图中的一个比特的值为0时，指示该比特对应的时隙组被静默，不能用于PRS传输；第一比特位图中的一个比特的值为1时，指示该比特对应的时隙组可以允许用于PRS传输。
基于比特的值为0或1进行指示只是示例性的，本公开实施例中对指示方式不做具体限定。
终端可以基于第一比特位图中每一个比特的值对应的指示，确定PRS静默的时隙组。
例如，第一比特位图中有M位比特，表示为(a0,a1,…,aM-2,aM-1)，第一比特位图中的一个比特ai,i＝0,1,…,M-1，对应一个时隙组，每个时隙组包含L个时隙。
第一比特位图中a1和aM-2的值为1，其他比特的值为0，指示a1对应的时隙组和aM-2对应的时隙组被静默，不能用于PRS传输；而其余比特对应的时隙组可以用于PRS传输。
本公开实施例提供的PRS静默方法，通过向终端发送与时隙组对应的第一比特位图，以供终端基于第一比特位图的指示确定PRS静默的时隙组，进一步实现PRS静默，避免PRS之间的干扰。
在一些实施例中，第一比特位图的比特长度是基于预设总时隙数和一个时隙组中的时隙个数确定的。
具体地，预设总时隙数是系统预定义的，一个时隙组中的时隙个数可以是高层参数配置的。
第一比特位图的比特长度为时隙组的个数，时隙组的个数可以基于预设总时隙数和一个时隙组中的时隙个数进行确定，因此，第一比特位图的比特长度可以基于预设总时隙数和一个时隙组中的时隙个数进行确定。
第一比特位图的比特长度的表达式如下所示：
式中，M表示第一比特位图的比特长度，Tmax表示预设总时隙数，L表示一个时隙组中的时隙个数。
本公开实施例提供的PRS静默方法，基于预设总时隙数和一个时隙组中的时隙个数确定第一比特位图的比特长度，有利于终端基于第一比特位图确定PRS静默的时隙组。
在一些实施例中，比特位图包括第二比特位图；第二比特位图中的每一个比特对应一个时隙；第二比特位图用于指示PRS静默的时隙。
具体地，电子设备可以向终端发送配置的第二比特位图，还可以向终端发送配置的第一比特位图和第二比特位图。

例如，第二比特位图中的一个比特的值为1时，指示该比特对应的时隙被静默，不能用于PRS传输；第二比特位图中的一个比特的值为0时，指示该比特对应的时隙可以允许用于PRS传输。
或者例如，第二比特位图中的一个比特的值为0时，指示该比特对应的时隙被静默，不能用于PRS传输；第二比特位图中的一个比特的值为1时，指示该比特对应的时隙可以允许用于PRS传输。
基于比特的值为0或1进行指示只是示例性的，本公开实施例中对指示方式不做具体限定。
终端可以基于第二比特位图中每一个比特的值对应的指示，确定 PRS静默的时隙。
例如，第一比特位图表示为(a0,a1,…,aM-2,aM-1)，第一比特位图中的一个比特ai,i＝0,1,…,M-1，对应一个时隙组，每个时隙组包含L个时隙。a0对应的时隙组可以用于PRS传输，a0对应的时隙组包含L个时隙，分别为时隙0，时隙1，……，时隙L-2和时隙L-1。

第二比特位图中b0和bL-1的值为1，其他比特的值为0，指示b0对应的时隙0和bL-1对应的时隙L-1被静默，不能用于PRS传输；而其余比特对应的时隙可以用于PRS传输。
本公开实施例提供的PRS静默方法，通过向终端发送与时隙对应的第二比特位图，以供终端基于第二比特位图的指示确定PRS静默的时隙，进一步实现PRS静默，避免PRS之间的干扰。
在一些实施例中，比特位图还包括：第三比特位图；第三比特位图中的每一个比特对应一个时隙；第三比特位图用于指示允许传输PRS的时隙。
具体地，电子设备可以向终端发送配置的第一比特位图和第三比特位图，还可以向终端发送配置的第一比特位图、第三比特位图和第二比特位图。
第三比特位图的比特长度可以根据第一比特位图中每个比特对应的时隙组中的时隙个数进行确定。第三比特位图中的每一个比特对 应一个时隙。在第三比特位图中，比特的不同值对应不同的指示。
例如，第三比特位图中的一个比特的值为1时，指示该比特对应的时隙可以允许用于PRS传输。第三比特位图中的一个比特的值为0时，指示该比特对应的时隙被静默，不能用于PRS传输。
或者例如，第三比特位图中的一个比特的值为0时，指示该比特对应的时隙可以允许用于PRS传输。第三比特位图中的一个比特的值为1时，指示该比特对应的时隙被静默，不能用于PRS传输。
基于比特的值为0或1进行指示只是示例性的，本公开实施例中对指示方式不做具体限定。
终端可以基于第三比特位图中每一个比特的值对应的指示，确定允许传输PRS的时隙。
例如，第一比特位图表示为(a0,a1,…,aS-2,aS-1)，第一比特位图中的一个比特aq,q＝0,1,…,S-1，对应一个时隙组，每个时隙组包含N个时隙。a0对应的时隙组可以用于PRS传输，a0对应的时隙组包含N个时隙，分别为时隙0，时隙1，……，时隙N-2和时隙N-1。
第三比特位图中有N位比特，表示为(c0,1,…,cN-2,cN-1)，第三比特位图中的一个比特Cn,n＝0,1,…,N-1，对应一个时隙。c0对应时隙0，c1对应时隙1，……，cN-2对应时隙N-2，cN-1对应时隙N-1。
在第三比特位图中，除c1和cN-2的值为0外，其他比特的值为1，指示c1对应的时隙1和cN-2对应的时隙N-2被静默，不能用于PRS传输；而其余比特对应的时隙可以用于PRS传输。
本公开实施例提供的PRS静默方法，通过向终端发送与时隙对 应的第三比特位图，以供终端基于第三比特位图的指示确定用于PRS传输的时隙，进一步实现PRS静默，避免PRS之间的干扰。
在一些实施例中，第二比特位图的比特长度是基于第三比特位图中用于指示允许传输PRS的时隙个数确定的；或者，是基于信令配置的。
具体地，第二比特位图的比特长度可以是基于高层信令配置的。例如，配置第二比特位图的比特长度为K，K为正整数。
第二比特位图的比特长度可以是基于第三比特位图中用于指示允许传输PRS的时隙个数确定的，也就是第二比特位图的比特长度等于第三比特位图中用于指示允许传输PRS的时隙个数。
例如，第三比特位图表示为(c0,c1,…,cN-2,cN-1)，第三比特位图中的一个比特Cn,n＝0,1,…,N-1，对应一个时隙。c0对应时隙0，c1对应时隙1，……，cN-2对应时隙N-2，cN-1对应时隙N-1。c1对应的时隙1和cN-2对应的时隙N-2被静默，不能用于PRS传输；而其余比特对应的时隙可以用于PRS传输。
可见，第三比特位图对应N个时隙，其中有N-2个时隙为允许传输PRS的时隙，则第二比特位图的比特长度为N-2，其中每一个比特对应一个允许传输PRS的时隙。b0对应时隙0，b1对应时隙2，……，bN-3对应时隙N-1。
本公开实施例提供的PRS静默方法，基于第三比特位图中用于指示允许传输PRS的时隙个数确定；或者，是基于信令配置确定第二比特位图的比特长度，有利于终端基于第二比特位图确定PRS静默的时隙，降低静默指示的开销。

第四比特位图的比特长度由高层配置。第四比特位图中的每一个比特对应预设数目个PRS周期对应的资源。预设数目个由高层配置的，记为PRS周期可以是基于PRS资源集的周期，还可以是基于PRS资源的周期。
例如，第四比特位图的比特长度为6，配置了为2，第四比特位图中一个比特对应2个PRS周期对应的资源。
终端可以基于第四比特位图中每一个比特的值对应的指示，确定PRS周期对应的资源是否被静默。
例如，第四比特位图中的第一个比特的值为1，表示第一个比特对应的2个PRS周期对应的资源被静默，不能用于PRS传输。
第五比特位图的比特长度为一个PRS周期内的重复因子个数，一个重复因子对应一次PRS重复，第五比特位图中的每一个比特对应PRS周期内一次PRS重复对应的资源。一次PRS重复对应的资源可以是一次重复的PRS资源集，还可以是一次重复的PRS资源。
例如，一个PRS周期内的重复因子为2，表示一个PRS周期内有两次PRS重复，则第五比特位图的比特长度为2，第五比特位图中 的每一个比特对应PRS周期内一次PRS重复对应的资源。
终端可以基于第五比特位图中每一个比特的值对应的指示，确定PRS重复对应的资源是否被静默。
例如，第五比特位图中的第一个比特的值为1，表示PRS周期内第一次PRS重复对应的资源被静默，不能用于PRS传输。
第六比特位图的比特长度为PRS资源集内的PRS资源个数，第六比特位图中的每一个比特对应PRS资源集中的一个PRS资源。
例如，PRS资源集内有4个PRS资源，分别是PRS资源0、PRS资源1、PRS资源2和PRS资源3，则第六比特位图的比特长度为4，第六比特位图中的每一个比特对应PRS资源集中的一个PRS资源。
终端可以基于第六比特位图中每一个比特的值对应的指示，确定PRS资源是否被静默。
例如，第六比特位图中的第二个比特的值为1，表示PRS资源1被静默，不能用于PRS传输。
