具体实施方式
下文中将结合附图对本申请的实施例进行说明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在一些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
在一个示例性实施方式中，图1为本申请实施例提供的一种确定方法的流程示意图，该方法可以适用于确定定位参考信号的图样的情况。该方法可以由本申请提供的确定装置执行，该装置可以由软件和/或硬件实现，并集成在通信节点上。通信节点涵盖任何适合类型的终端设备或基站。
本申请实施例的技术方案可以应用于各种通信系统，例如：LTE系统、LTE时分双工(Time Division Duplex，TDD)、LTE增强版本，通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、第五代移动通信系统(the 5th Generation mobile communication system，5G)NR通信系统，以及它们演进的版本或者其它未来的无线通信系统等。
基站可以是LTE中的演进型基站(Evolutional Node B，eNB或eNodeB)、5G网络中的基站设备、或者未来通信系统中的基站等，所述基站可以包括各种宏基站、微基站、家庭基站、无线拉远、路由器、位置服务器(即location server)、或者主小区(即primary cell)和协作小区(即secondary cell)等各种网络侧设备和定位管理功能(Location Management Function，LMF)设备中的一个或多个。
终端可以称为接入终端、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。例如，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、或者5G网络中的终端设备等。本申请对此并不限定。
定位参考信号包括在下行链路中用于定位的下行定位参考信号(Positioning Reference Signal，PRS)，以及用于定位的上行探测参考信号(Sounding reference signal，SRS)，也可以是其它的用于定位的参考信号。在基于终端协助定位或者基于终端的定位方法中，一般基站或者定位服务器发送PRS给需要定位的终端，终端通过PRS获得定位相关的参数。而基于基站的定位中，终端会发送用于定位的SRS，基站接收SRS并获得定位相关的参数。定位参考信号配置包括以下至少之一：定位参考信号的周期，定位参考信号的图样，定位参考信号的发送时隙、定位参考信号的时隙偏置(即offset)、定位参考信号序列、定位参考信号时隙持续个数N PRS、定位参考信号静默(即Muting)周期和偏置等。其中，定位参考信号图样为定位参考信号在一个或者多个时隙中占用的资源元素(Resource Element，RE)集合，对于周期定位参考信号来说，定位参考信号的周期和时隙偏置可以通过一个联合的参数定位参考信号配置索引(即configuration Index)I PRS确定，其中PRS muting周期和偏置用于计算不用传输PRS的时隙。其中，时隙为符号组合，包括至少2个符号，其中符号包括但不限于正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号，正交频分复用多址接入(Carrier Frequency Division Multiple Access，OFDMA)符号，单载波正交频分复用多址接入(Single-Carrier Frequency Division Multiple Access，SC-OFDM)符号。本申请中的确定方法可以认为是参考信号配置方法，主要是定位参考信号的图样确定方法。
正交覆盖码(Orthogonal Covering Code，OCC)是一个正交向量的集合，每个正交覆盖码都是一个长度为K OCC的向量，长度K OCC称为正交覆盖码的长度。比如K OCC为2时，包括两个正交覆盖码[1 1]和[1-1]；比如K OCC为4时，可以 包括至少四个正交覆盖码[1 1 1 1]和[1 -1 1 -1]、[1 -1 -1 1]和[-1 -1 1 1]。所述的OCC可以应用于时域上的不同符号上的RE，可以称为时域正交覆盖码，即OCC码中所有的元素都应用于时域RE，对应的长度为OCC时域长度；所述的OCC可以应用于同一个符号不同频域上的RE，可以称为频域正交覆盖码，即OCC码中所有的元素都应用于频域RE，对应的长度为OCC频域长度；所述的OCC可以应用于多个符号多个频域上的RE，可以称为时频正交覆盖码。即OCC码中部分元素都应用于时域RE，对应的长度为OCC时域长度，部分元素都应用于频域RE，对应的长度为OCC频域长度。
正交覆盖码的时域间隔是指正交覆盖码的两个元素中对应的RE的时域符号的间隔。在所述正交覆盖码的时域间隔为1的情况下，所述正交覆盖码的元素对应的RE在时域符号上是连续的，否则是非连续的。
如图1所示，本申请提供的一种确定方法，包括如下步骤：
S110、确定定位参考信号的梳和正交覆盖码。
本申请可以通过确定定位参考信号的图样减小定位无线通信系统的干扰。确定定位参考信号的梳和正交覆盖码的手段此处不作限定，可以根据实际情况确定。
S120、基于所述梳和所述正交覆盖码，确定所述定位参考信号的图样。
确定梳和正交覆盖码的情况下，本步骤可以基于梳和正交覆盖码，确定定位参考信号的图样，以基于确定的图样传输定位参考信号，从而减少定位无线通信系统的干扰。
在一个实施例中，本申请可以根据如下一个或多个信息确定定位参考信号的图样：梳的取值；正交覆盖码的长度；正交覆盖码的连续性；正交覆盖码所属资源。连续性包括连续和非连续。所属资源至少包括时域和频域，正交覆盖码的长度包括正交覆盖码的时域长度，即一个正交覆盖码所对应的时域RE个数(或符号个数)，和正交覆盖码的频域长度，即一个正交覆盖码所对应的频域RE个数(或子载波个数)。
此处不限定确定手段，只要保证定位参考信号所对应的每个符号对应的起始资源元素(Resource Element，RE)的间隔大于设定距离即可(即使得相邻起始RE的距离尽量大)，设定距离的设定可以根据实际情况设定，此处不作限定。这里定位参考信号所对应的每个符号对应的起始资源元素也可以称为资源元素的偏置(即Resource element offset)或者频域资源元素偏置，或者频域偏置，即frequency offset，或者偏置，即offset，可以记为k’。

以下对本申请进行示例性的描述：
本申请提供的确定方法可以认为是一种定位参考信号的配置方法，如配置定位参考信号的图样。
定位是各种无线通信系统中一种比较常用的应用。而在定位中由于需要用到多个基站，从而导频开销也比较大，而非服务小区的信干噪比(Signal to  Interference plus Noise Ratio，SINR)一般来说是比较低的，为了对非服务小区的导频估计，需要用到静默，即muting技术，而这会增加导频的开销，为了在不增加导频开销的情况下定位，需要设计一些新的导频图样。
图1a为本申请实施例提供的一种定位场景示意图，参见图1a，室内的基站数目可能较少，但是传输接收点(Transmission Reception Point，TRP)数目较多，同一个基站下所有TRP的单频网络(Single Frequency Network，SFN)是相同的，高频进行波束扫描时，为了避免干扰，很可能造成下行链路定位参考信号(Positioning Reference Signal，PRS)的静默较多。特定TRP的下行PRS时域周期较大，影响定位精度。每个TRP需要服务的用户设备(User Equipment，UE)数目较多，发给每个TRP的上行PRS可能会造成干扰，因此需要提升上行PRS的复用能力。
图1b为本申请实施例提供的一种定位参考信号的图样示意图；图1c为本申请实施例提供的又一种定位参考信号的图样示意图；图1d为本申请实施例提供的又一种定位参考信号的图样示意图；图1e为本申请实施例提供的又一种定位参考信号的图样示意图。图1b-1e中横坐标可以表示时域，纵坐标可以表示频域，本申请中下述图样示意图可以相同，即横坐标表示时域，纵坐标表示频域。参见图1b-1e，在正交覆盖码为时域正交覆盖码(Time Domain-Orthogonal Cover Code，TD-OCC)，正交覆盖码(Orthogonal Cover Code，OCC)是连续的，且时域长度为2的情况下，若梳，即Comb的取值为2(即Comb-2)，则定位参考信号每个所对应的符号对应的资源元素偏置依次为(0，0，1，1)；若Comb的取值为4(即Comb-4)，则定位参考信号所对应的每个符号对应的资源元素偏置依次为(0，0，2，2，1，1，3，3)；若Comb的取值为6(即Comb-6)，则定位参考信号所对应的每个符号对应的资源元素偏置依次为(0，0，3，3，1，1，4，4，2，2，5，5)；若Comb的取值为8(即Comb-8)，则联合两个时隙，定位参考信号所对应的每个符号对应的资源元素偏置依次为(0，0，4，4，2，2，6，6，1，1，5，5，3，3，7，7)；若Comb的取值为12(即Comb-12)，则联合两个时隙，定位参考信号所对应的每个符号对应的资源元素偏置依次为(0，0，6，6，3，3，9，9，1，1，7，7，4，4，10，10，2，2，8，8，5，5，11，11)。

图1i为本申请实施例提供的又一种定位参考信号的图样示意图；参见图1i，在正交覆盖码为TD-OCC，OCC是非连续的，且时域长度为4的情况下，若Comb的取值为2(即Comb-2)，则定位参考信号所对应的每个符号对应的资源元素偏置依次为(0，1，0，1，0，1，0，1)。此外，若Comb的取值为4(即Comb-4)，则联合两个时隙，定位参考信号所对应的每个符号对应的资源元素偏置依次为(0，2，1，3，0，2，1，3，0，2，1，3，0，2，1，3)；若Comb的取值为6(即Comb-6)，则联合两个时隙，定位参考信号所对应的每个符号对应的资源元素偏置依次为(0，3，1，4，2，5，0，3，1，4，2，5，0，3，1，4，2，5，0，3，1，4，2，5)。

本申请提供的确定方法，对于频率范围1(Frequency Range1，FR1)而言，可以减小或不适用下行PRS静默。对于FR2，除非UE有同一个时刻接受多个波束的能力，否则需要下行PRS静默。其中，FR1的频率范围可以为450MHz-6000MHz，FR2的频率范围可以为24250MHz-52600MHz。时域OCC能够提高接收功率，如，在发射总功率一定的情况下，Comb-2每个UE的接收功率和16版本的Comb-2的方案可以是相同的。
