具体实施方式

其中,该无线短距离通信系统可以为基于任意无线短距离通信技术的通信系统。该无线短距离通信系统可以有多种可能,如,可以为支持低功耗通信技术的无线短距离通信系统或者其他类型的无线短距离通信系统等,本申请对此不加限制。
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清楚、完整地描述,显然,所描述的实施例仅仅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付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。
在本申请的无线短距离通信系统中的节点可以包括管理节点以及至少一个被管理节点。该管理节点与至少一个被管理节点之间建立有无线网络连接。管理节点与这些被管理节点连接共同完成特定的通信功能,管理节点与其连接的被管理节点共同组成了一个通信域。
为了便于理解,下面先从管理节点侧对本申请的方案进行介绍。
如图1所示,其示出了本申请实施例提供的获取物理层测量数据的方法,应用于无线短距离通信系统中的管理节点。
本实施例的方法可以包括:
S101,发送测量请求帧。
该测量请求帧中包括:物理层测量配置信息。该物理层测量配置信息中可以配置用于指示物理层测量相关的配置信息。
在本实施例中,该物理层测量配置信息至少包括:至少一个目标被管理节点的标识。目标被管理节点为管理节点确定出的需要提供管理节点执行物理层测量所需数据的被管理节点,因此,该目标管理节点属于该管理节点连接的至少一个被管理节点。
可以理解的是,物理层测量可以是任意涉及到信道估计相关的测量。如,物理层测量包括信道质量、测距、角度以及感知等相关测量项目,本申请对此不加限制。
其中,根据物理层测量的测量目标(或者说测量需求)不同,该物理层测量配置信息中所包含的具体内容也会有所不同。
如,在一种可能的实现方式中,该物理层测量配置信息可以包括如下几项内容中的部分或者全部:
测量请求帧标识,用于指示目标被管理节点启动导频符号发送;
测量请求节点标识,用于指示发送该测量请求帧的该管理节点;
被请求节点标识,用于指示发送导频符号的目标被管理节点;
待测量无线信道编号,用于指示需要进行物理层测量的无线信道;
导频符号格式指示,用于指示导频符号的传输格式信息。
其中,测量请求帧标识用于表征该测量请求帧所属的帧类型为用于请求导频符号的无线帧。
在本申请中,测量请求节点标识就是该管理节点的标识。被请求节点的标识也就是上面提到的目标被管理节点的标识,该被请求节点的标识可以有一个或者多个。
其中,该导频符号格式指示中可以包括用于指示导频符号的具体类型和格式以及传输方式等的相关信息。如,导频符号格式指示中可以包括导频符号的序列生成系数,长度、导频符号发送时刻和导频符号的发射功率等信息中的一种或者多种。
当然,在实际应用中,测量请求帧的物理层控制信息中还可以根据需要配置其他物理层测量信息以及其他相关的控制信息,对此不加限制。
在本申请中,该物理层测量配置信息包括在该测量请求帧中的物理层控制信息和物理层数据信息中的一种或者两种内。
如,该物理层测量配置信息可以包括在该测量请求帧的物理层控制信息内或者是包括在物理层数据信息内。
又如,可以是将物理层测量配置信息的部分内容包括在物理层控制信息内,而将剩余部分内容包括在物理层数据信息内,例如,将物理层测量配置信息中请测量请求节点标识、被请求节点标识和测量请求帧标识包括在物理层控制信息中,而将导频符号格式指示等信息包括在物理层数据信息内。
在本申请中该测量请求帧的帧结构可以有多种可能,在该测量请求帧的帧结构中至少包括该物理层控制信息和物理层数据信息。
在一种可能的实现方式中,该测量请求帧的帧结构可以依次包括:前导、同步信号、物理层控制信息和物理层数据信息这四个部分。在此基础上,可以将物理层测量配置信息包括在该测量请求帧中物理层控制信息和物理层数据信息这两部分中的至少一个或者两个内。
如图2和图3所示,图2和图3示出了该测量请求帧的两种组成结构示意图。
在图2中,测量请求帧的帧结构包括前导21、同步信号22、物理层控制信息23和物理层数据信息24四个部分,其中,物理层控制信息23中包括有该物理层测量配置信息。通过该种形式的测量请求帧可以指示目标被管理节点及时发送测量信号,使得管理节点可以实时进行信道质量测量等物理层测 量。在该种情况中,物理层数据信息中可以不携带数据,当然,也可以根据需要携带一些数据,对此不加限制。
由图3可以看出,测量请求帧的帧结构包括测量请求帧包括前导31、同步信号32、物理层控制信息33和物理层数据信息34。在图3中,在测量请求帧的物理层数据信息34中包括有该物理层测量配置信息,针对该种情况,可以预先通过无线短距离通信系统的协议机构中的基础服务层等高层进行定义,以明确测量请求帧中的物理层数据信息用于携带物理层测量配置信息。由于物理层测量配置信息被包括在物理层数据信息中,在该种情况下,该测量请求帧可以作为普通数据包发送。
S102,获得该目标被管理节点返回的测量帧。
其中,该测量帧包括:用于物理层测量的导频符号。
可以理解的是,导频符号在信道传输过程中,由于受到信道噪声干扰以及其他因素等影响,目标被管理节点发出的导频符号与管理节点接收到的导频符号会存在差异。但由于导频符号是管理节点指示目标被管理节点发送的,管理节点可以获知目标被管理节点实际发出的导频符号,在此基础上,管理节点可以结合目标被管理节点实际应发出的导频符号以及管理节点实际接收到的导频符号来进行信道估计等操作,最终完成物理层测量。对于管理节点基于导频符号进行物理层测量的相关处理,本申请不加限制。
在本申请中,该导频符号可以包括在测量帧的物理层数据信息中。
在本申请中,该测量帧的帧结构中至少包括物理层数据信息。
可以理解的是,为了使得管理节点可以确定测量帧的目的节点为自身,该测量帧中还可以包括请求节点标识,该请求节点标识用于指示请求导频符号的该管理节点,因此,该请求节点标识也就是该管理节点的标识。
在本申请中,该测量帧的帧结构中还可以包括物理层控制信息,因此,该请求节点标识可以配置于该物理层控制信息中。
可以理解的是,该测量帧中的物理层控制信息还可以包括其他信息,对此不加限制。
如,在一种可能的实现方式中,该测量帧中的物理层控制信息可以包括如下几种信息中的部分或者全部:
测量帧标识,用于指示管理节点启动导频符号接收;
请求节点标识,用于指示请求导频符号的该管理节点;
发送节点标识,用于指示发送该测量帧的目标被管理节点;
导频符号格式指示,用于指示该导频符号的传输格式信息。
其中,测量帧标识用于表征该测量帧为用于物理层测量所需的无线帧。
在本申请中,该请求节点标识也就是发起物理层测量的该管理节点的标识。该发送节点标识也就是发送该测量帧的目标被管理节点的标识。
测量帧中的导频符号格式指示可以包括:目标被管理节点实际发送导频符号所采用的传输格式等信息。如,该测量帧中的导频符号格式指示可以包括:导频符号的序列生成系数,长度以及导频符号的发射功率等等。
可以理解的是,前面测量请求帧中的导频符号格式指示中的相关格式以及传输要求等信息为管理节点希望被管理节点发送导频符号的格式以及传输方式等的信息。而测量帧中的导频符号格式指示包括的是目标被管理节点实际发送导频符号的相关传输格式等信息。
在实际应用中,如果目标被管理节点按照管理节点发送的测量请求帧中导频符号格式指示所要求的传输格式来传输导频符号,该测量帧中的导频符号格式指示中也可以不包含导频符号的传输格式等信息、
在本申请中,该测量帧的帧结构也可以有多种可能。如,在一种可能的情况中。该测量帧的帧结构中可以依次包括:前导、同步信号、物理层控制信息和物理层数据信息。
为了便于理解,可以参见图4,图4示出了测量帧的一种组成结构示意图。由图4可以看出,该测量帧的帧结构中依次包括前导41、同步信号42、物理层控制信息43和物理层数据信息44。
其中,物理层数据信息44中可以包括导频符号。
该物理层控制信息中可以包括如上提到的测量帧标识、请求节点标识以及导频符号格式指示等等信息。
可以理解的是,在本申请中,由于测量帧用于发送物理层测量所需的导频符号,而该导频符号可以配置于测量帧的物理层数据信息中,但是由于物理层测量信息中的导频符号不同于常规无线帧中携带的数据,因此,在该测量帧的物理层数据信息中可以不携带循环校验位。
在本申请中,导频符号的具体形式可以有多种可能,具体可以根据物理层测量需求的不同采用不同的形式。
如,导频符号的具体形式可以有如下几种可能情况:
一种可能情况中,导频符号可以采用m序列(最长线性移位寄存器序列),采用m序列的导频符号可用于信道状态信息测量、信号强度测量以及信道接收质量测量等等。
在又一种可能的情况中,导频符号可以采用Gold序列,Gold序列为在m序列基础上提出并分析的一种特性较好的伪随机序列。采用Gold序列的导频符号可用于信道状态信息测量、信号强度测量以及信道接收质量测量等等。
在又一种可能的情况中,导频符号可以采用ZC(Zadoff-Chu)序列的形式,采用该种形式的导频符号可以用于感知、测距、定位、方向和测量等物理层相关测量。
由以上内容可知,本申请中无线短距离通信系统中的管理节点发送的测量请求帧中包括物理层测量配置信息,该物理层测量配置信息中可以包括需要执行物理层测量的目标被管理节点的标识。相应的,目标被管理节点可以向该管理节点返回测量帧,在该测量帧中的物理层数据信息中可以包括用于物理层测量的导频符号。由此可见,本申请中管理节点可以通过测量请求帧指示目标被管理节点返回携带导频符号的测量帧,而无需借助物理层之间用于传输数据的无线帧,因此,即使管理节点与被管理节点之间不存在数据交互,也可以通过测量请求帧与测量帧来获取用于物理层测量的数据。
在本申请中,管理节点发送测量请求帧的形式也可以有多种可能。
如,在一种可能的情况中,管理节点可以采用单播的形式发送测量请求帧。在该种可能的情况下,管理节点发送的测量请求帧中的物理层测量配置信息内仅仅配置有一个目标被管理节点的标识,管理节点与目标被管理节点之间通过点对点形式传输测量请求帧以及测量帧。
如图5所示,其示出了单播形式下管理节点发送的测量请求帧与接收到的测量帧之间的对应关系。由图5可以看出,在采用单播形式发送测量请求帧的情况下,管理节点发出一个测量请求帧之后,会触发一个目标被管理节点生成并返回测量帧。
在又一种可能的情况中,管理节点可以采用组播的形式发送测量请求帧。相应的,测量请求帧中物理层测量配置信息中可以包括多个目标被管理节点的标识。在该种情况中,管理节点与多个目标被管理节点通信,并要求所有的目标被管理节点发送测量帧。
可以理解的是,由于多个目标管理节点均会向管理节点返回测量帧,为了保证管理节点可以可靠接收到各目标管理节点返回的测量帧,管理节点可以要求不同的目标被管理节点在不同时刻发送测量帧。
基于此,管理节点可以在测量请求帧中的导频符号指示格式中设置多个目标被管理节点的标识各自对应的导频符号发送时刻。在管理节点发送测量请求帧后,目标被管理节点可以在测量请求帧中该目标管理节点的标识对应的导频符号发送时刻,向该管理节点发送导频符号。
如图6所示,其示出了管理节点采用组播形式发送测量请求帧的情况下,测量请求帧与各目标被管理节点发送的测量帧之间对应关系的示意图。
在图6中以多个目标被管理节点包括目标被管理节点T1、目标被管理节点T2和目标被管理节点T3为例说明。
同时,在图6中测量帧在直线上的位置先后顺序用于表征测量帧的发送时刻的先后顺序。
由图6可以看出,管理节点每次采用组播形式发送测量请求帧后,这三个目标被管理节点分别在不同时间上向管理节点返回测量帧。
可以理解的是,通过在测量请求帧中导频符号格式指示中配置不同目标被管理节点对应的导频符号发送时刻,可以利用不同的时间资源来实现资源间的正交复用。
当然,在实际应用中,也可以是预先基于无线短距离通信系统的协议架构中的基础服务层通过信令预先确定导频符号的发送时刻,对此不加限制。
当然,对于单播形式发送测量请求帧的情况,管理节点同样可以在测量请求帧的导频符号格式指示中配置导频符号发送时刻,对此不加限制。
在本申请以上任意一个实施例中,根据物理层测量的实际需要,管理节点还可以配置每个目标被管理节点在多个频段(也称为频点)上发送测量帧,以使得管理节点可以在多个不同频段上接收该目标被管理节点返回的测量帧。为了实现该目的,管理节点还可以在测量请求帧中的物理层测量配置信 息的待测量无线信道编码中设置待测量的多个频段各自对应的无线信道编码。
进一步的,管理节点还可以在该物理层测量配置信息的导频符号格式指示中设置:各目标被管理节点的标识分别在多个频段上的导频符号发送时刻。
为了便于理解,在多频段进行物理层测量的情况下,管理节点发送的测量请求帧与目标被管理节点返回的测量帧之间的对应关系,可以参见图7。
由图7可以看出,针对每个目标被管理节点,该管理节点发送测量请求帧之后,每个目标被管理节点(如图7中的T节点)需要在多个频段上返回测量帧。
而且,目标被管理节点在不同频段上发送测量帧的时刻也不同。如图7中,测量帧从左到右的先后顺序表征了测量帧发送的先后时刻,结合图7可以看出,目标被管理节点在不同频段的信道上返回测量帧的时刻不同,从而可以使得管理节点可以在不同时刻分别接收该目标被管理节点在不同频段上返回的测量帧,以保证管理节点对于不同频段上返回的测量帧的可靠接收。
为了便于理解,目标被管理节点侧的操作,下面从目标被管理节点侧对本申请的方案进行介绍。
如图8所示,其示出了本申请实施例提供的物理层测量数据发送方法的一种流程示意图,本实施例的方法应用于无线短距离通信系统中的被管理节点。本实施例的方法可以包括:
S801,接收到测量请求帧。
该测量请求帧中包括物理层测量配置信息,该测量配置信息包括在该测量请求帧中的物理层控制信息和物理层数据信息中的一种或者两种内。
在本申请中物理层测量配置信息包括:被管理节点的标识和测量请求节点标识,该测量请求节点标识用于指示发送该测量请求帧的管理节点。
该被管理节点的标识属于物理层测量配置信息中配置的被请求节点的标识。相应的,接收到该测量请求帧的被管理节点实际上就是前面提到的目标被管理节点。
在本实施例中,关于测量请求帧的帧结构以及包含的物理层测量配置信息的具体内容可以参见前面实施例的相关介绍,在此不再赘述。
S802,发送测量帧。
该测量帧包括:用于物理层测量的导频符号。
该导频符号包括在该测量帧的物理层数据信息中,且该测量帧的物理层控制信息中包括请求节点标识,该请求节点标识用于指示请求该导频符号的该管理节点。
可以理解的是,测量帧的具体结构组成等同样可以参见前面实施例的相关介绍,在此不再赘述。
在一种可能的实现方式中,如果在测量请求帧中通过物理层测量配置信息中的导频符号格式指示中包括了目标被管理节点的标识对应的导频符号发送时刻,那么该目标被管理节点可以在到达其对应的导频符号发送时刻时,发送该测量帧。
在又一种可能的实现方式中,如果测量请求帧中的物理层测量配置信息中包括待测量的多个频段各自对应的无线信道编号,且在导频符号格式指示中包括:该目标被管理节点的标识分别在该多个频段上的导频符号发送时刻,那么针对多个频段中的每个频段,目标被管理节点可以按照该频段对应的导频符号发送时刻,在到达该导频符号发送时刻时,在该频段的无线信道上发送导频符号。
可以理解的是,由于被管理节点在接收到测量请求帧之后,便可以向管理节点返回包含导频符号的测量帧,使得管理节点可以基于接收到的导频符号进行物理层测量,从而使得物理层测量可以不受管理节点与被管理节点之间是否存在数据交互的限制。
可以理解的是,在本申请以上实施例中,管理节点可以基于配置的无线短距离通信协议中基础服务层中的测量管理功能模块的需求,确定物理层测量需求。在此基础上,结合物理层测量需求,管理节点可以在测量请求帧中配置相应的物理层测量配置信息。
可以理解的是,在本申请以上实施例中,管理节点在发送请求帧之前,还可以从管理节点连接的至少一个被管理节点中,确定用于执行物理层测量的至少一个目标被管理节点。
其中,管理节点在确定出物理层测量的目标之后,可以查询具备该物理层测量能力的至少一个目标被管理节点。该管理节点可以基于无线短距离通 信协议中的连接管理功能单元对各目标被管理节点进行物理层测量能力的查询,以确定具备该物理层测量能力的至少一个目标被管理节点。
如,管理节点可以基于连接管理功能单元,通过广播等形式查询各个被管理节点是否具备实现相应的物理层测量的能力,在此基础上,结合各个被管理节点返回的查询结果,便可以确定具备该物理层测量能力的被管理节点。
为了便于理解本申请的方案及其好处,下面以一种无线短距离通信系统的可能情况为例说明。
如,无线短距离通信系统中,管理节点可以称为G节点,被管理节点称为T节点。
本申请的发明人经过研究发现:该无线短距离通信系统中引入了低功耗通信技术。在基于低功耗通信技术的无线短距离通信系统中,在G节点指示T节点进行物理层测量之后,T节点会将用于物理层测量的导频符号插入到无线帧的物理层数据信息中。
如图9,其示出了一种无线短距离通信系统中无线帧的一种结构示意图。
由图9可以看出,该无线帧的帧结构依次包括:前导、同步信号、物理层控制信息和物理层数据信息。其中,在物理层数据信息中引入了导频符号901,并且该导频符号901在时域上是以等间隔的方式插入到物理层数据信息中,与物理层数据信息中的数据符号一同进行相位旋转等编码处理。由图9可以看出,在物理层数据信息中每间隔一定数量的数据符号会插入有一个导频符号901。
具体的,导频符号插入到该物理层数据信息中的插入间隔收到导频密度信令控制可以分为4:1、8:1以及16:1这三种情况。其中,4:1是指每间隔4个数据符号插入一个导频符号;8:1是指每间隔8个数据符号插入一个导频符号;16:1是指每间隔16个数据符号插入一个导频符号。
结合图9可以看出,该无线短距离通信系统中,用于物理层测量的导频符号是随数据一起发送的,如果无线短距离通信系统的设备节点之间一旦没有数据交互,那么就不存在携带数据符号的无线帧传输,自然也就无法向无线帧中插入导频符号,也就无法实现物理层测量。
基于此,利用本申请的方案定义的测量请求帧、测量帧以及相应的物理层测量的信令交互机制,可以有效管理节点与被管理节点之间传输物理层测量所需的导频符号,也就可以支持在无数据交互情况下的物理层测量。
下面结合无线短距离通信系统的一种场景,对本申请的物理层测量所涉及到的测量请求帧与无线帧等信令交互过程进行介绍。
首先介绍下,在场景中无线短距离通信系统的协议架构,如图10所示。
由图10可知,该协议架构从上到下各层依次为:基础应用层、基础服务层以及接入层。
接入层引入了协议基础功能单元和低功耗功能单元
其中,基础应用层与基础服务层之间可以经IP协议与传输控制协议(TCP,Transmission Control Protocol)或者用户数据包协议(UDP,User Datagram Protocol)传输协议进行通信传输。
在该基础服务层中可以包括数据传输与适配、设备发现以及通用管理等协议功能单元。
在该无线短距离通信系统的协议架构中,测量管理这一功能单元统一负责基础服务层以及接入层相关性能参数的测量以及状态监管。
针对接入层,该测量管理功能单元通过跨层原语调用可以支持采集包括RSRP(参考信号接收功率)、RSSI(接收的信号强度指示)、RSRQ(参考信号接收质量)、SINR(信号与干扰加噪声比)、误码率、收发速率、AoA(到达角度)、AoD(离开角度)、ToF(飞行时间)等在内的物理层参数信息。
针对基础服务层流模式或可靠模式下的传输通道,测量功能单元支持测量端到端时延、抖动等性能指标测量。
其中,跨层原语包括物理层参数查询请求、物理层参数上报、物理层参数查询取消以及物理层参数查询取消确认等。
下面结合以上无线短距离通信系统的协议架构,对本申请的方案进行介绍,如图11所示,其示出了本申请实施例提供的物理层测量方法的一种流程 交互示意图,该流程包含了物理层测量数据的获取以及物理层测量数据发送两部分内容。
本实施例的方法可以包括:
S1101,管理节点查询各被管理节点是否具备执行指定的物理层测量的能力,得到各被管理节点的查询结果。
其中,该查询结果可以表征被管理节点是否具备执行该物理层测量的能力。
如图11可知,管理节点可以结合无线短距离通信系统的协议结构中的连接管理功能单元与被管理节点的连接管理功能单元进行通信,以确定被管理节点是否具备执行指定的物理层测量的能力。
例如,管理节点需要执行信道质量测量,则需要查询被管理节点是否具备提供信道质量测量所需的导频符号的发送等相关能力。
可以理解的是,对于管理节点查询各被管理节点是否具备物理层测量能力的具体实现方式可以有多种可能,对此不加限制。
S1102,管理节点结合各被管理节点的查询结果,确定用于执行该物理层测量的至少一个目标被管理节点,并与目标被管理节点进行测量信息的协商。
如,管理节点确定查询结果表征具备该物理层测量能力的至少一个被管理节点,然后结合物理层测量的目的,从确定出的被管理节点中确定出一个或者多个目标被管理节点。
其中,管理节点与目标被管理节点可以结合协议架构上的测量管理功能单元来进行测量信息协商,此处测量信息协商也就是俗称的确定测量实例及建立测量实例。其中,每个测量实例对应一个物理层测量的具体测量项。
通过测量信息协商可以确定物理层测量的一些配置信息,如前面提到的物理层测量配置信息中的部分信息,例如导频符号的发送时刻,无线信道标识等;还可以包括物理层测量配置信息之外的一些同步时钟源类型以及测量模式(单向测量或者双向测量)等等信息,对此不加限制。
在完成测量实例的建立,便可以触发测量请求帧的发送。
S1103,管理节点发送测量请求帧。
该测量请求帧中可以包括物理层测量配置信息。
如,该物理层测量配置信息该物理层测量配置信息可以包括如下几项内容:
测量请求帧标识;
测量请求节点标识;
被请求节点标识,其中,被请求节点标识可以有一个或者多个;
待测量无线信道编号;
导频符号格式指示。
该物理层测量配置信息可以配置于测量请求帧的物理层控制信息内或者物理层数据信息内。当然,也可以是将物理层配置信息中的一部分内容包括在测量请求帧的物理层控制信息层,另一部分包括在测量请求帧的物理层数据信息内。
关于测量请求帧的具体结构可以参见前面的相关介绍,在此不再赘述。
S1104,目标被管理节点向管理节点返回测量帧。
测量帧中可以包括用于物理层测量的导频符号,导频符号可以包括在该测量帧的物理层数据信息内。
同时,在该测量帧的物理层控制信息中可以包括测量帧标识、请求节点标识、发送节点标识以及导频符号格式指示等等,具体可以参见前面的相关介绍,在此不再赘述。
S1105,管理节点结合接收到的测量请求帧内的导频符号确定物理层测量结果。
可以理解的是,以上是结合一种无线短距离通信系统的协议架构以及物理层测量过程为例说明,但是可以理解的是,对于基于其他协议架构的无线短距离通信系统也同样适用,对此不加限制。
对应本申请的一种获取物理层测量数据的方法,本申请还提供了一种获取物理层测量数据的装置。
