Description

辅助信息接收、发送方法和装置、通信装置及存储介质 技术领域
本公开涉及通信技术领域，具体而言，涉及辅助信息接收方法、辅助信息发送方法、辅助信息接收装置、辅助信息发送装置、通信装置和计算机可读存储介质。
背景技术
5G NR(New Radio，新空口)引入了多种定位技术，可以实现对终端的定位。但为了更进一步提高定位精度，5G NR开始考虑基于载波相位carrier phase的定位方法。
其中，基于carrier phase的定位方法的基本原理是计算载波相位和整周数，通过载波相位和整周数就计算出信号从发射端到接收端的传输时延，进而根据传输时延计算出距离。由于载波信号是一种周期性正弦信号，在相位测量中只能测定其不足一个周期(即波长)的小数部分，而整周很难直接测量得出。
发明内容
有鉴于此，本公开的实施例提出了辅助信息接收方法、辅助信息发送方法、辅助信息接收装置、辅助信息发送装置、通信装置和计算机可读存储介质，以解决相关技术中的技术问题。

图1是根据本公开的实施例示出的一种辅助信息接收方法的示意流程图。本实施例所示的辅助信息接收方法可以适用于终端，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述终端可以与网络设备通信，所述网络设备包括但不限于4G、5G、6G等通信系统中的网络设备，例如基站、核心网等。
如图1所示，所述辅助信息接收方法可以包括以下步骤：
在步骤S101中，接收网络设备发送的辅助信息，其中，所述辅助信息用于辅助所述终端进行载波相位定位。
在一个实施例中，终端在基于载波相位对终端进行定位时，需要一些辅助信息才能进行精确定位。
例如在基于载波相位对终端进行定位时，引入了载波相位参考点(可以是一个，也可以是多个)，其中，载波相位参考点可以是终端相同或相近的通信装置，且载波相位参考点的位置是已知的，载波相位参考点与终端都可以对发送接收点TRP(Transmission/Reception Point)发出的定位参考信号进行测量。
在一个实施例中，所述载波相位参考点包括定位参考单元PRU(positioning reference unit)。
其中，在地面网络中，所述TRP可以包括基站，在非地面网络中，所述TRP可以包括卫星。
但是载波相位参考点的位置与终端的位置不同，所以测量定位参考信号得到的测量信息会有所差异，终端可以根据自身测量定位参考信号得到的测量信息与载波相位参考点测量定位参考信号得到的测量信息进行载波相位定位。当然，应当理解的是，终端进行载波相位定位所使用的信息，并不限于这两部分测量信息。
由于终端进行载波相位定位需要多个信息，而终端在处于蜂窝网络(也可以称作移动网络)中时，主要是与网络设备通信，一般并不能与载波相位参考点直接通信，因此，如何确保终端能够获取到足够的信息，以顺利进行载波相位定位，是亟待解决的技术问题。
根据本公开的实施例，网络设备可以获取供终端进行载波相位定位的辅助信息，并将辅助信息发送至终端。终端在接收到网络设备辅助后，可以根据辅助信息进行载波相位定位，以确保终端能够顺利进行载波相位定位。

而所述辅助信息可以由核心网确定，也可以由核心网从载波相位参考点获取。例如核心网可以通过向载波相位参考点发送LPP信息以请求所述辅助信息，例如向载波相位参考点发送LPP location information request(LPP位置信息请求)；载波相位参考点可以通过LPP信息将辅助信息发送至核心网，例如通过LPP provide location information(LPP提供位置信息)将辅助信息发送至核心网。
在一个实施例中，所述辅助信息包括以下至少之一：
载波相位参考点的位置信息，例如在地心地固(Earth-Centered，Earth-Fixed，ECEF)坐标系中的位置；

所述定位参考信号的配置信息，例如定位参考信号的时域资源、频域资源等；
载波相位参考残差；
所述载波相位参考点的标识，由于定位过程中可以使用一个或多个载波相位参考点，当使用多个载波相位参考点时，根据标识可以确定测量信息是由哪个载波相位参考点测量得到的；
所述发送接收点TRP的标识，例如TRP ID、CGI ID(Cell Global Identity，小区全球标识)。
在一个实施例中，所述测量信息包括以下至少之一：
所述载波相位参考点与发送所述定位参考信号的发送接收点之间的伪距，例如载波相位参考点可以根据TRP发送定位参考信号的发送时间和接收到定位参考信号的到达时间之间的时间差得到；
测量所述定位参考信号得到的载波相位，其中，所述载波相位包括整周数目和非整周数值(也即没有达到整周的小数部分)；
所述载波相位随时间的变化率，例如载波相位参考点接收到的定位参考信号的载波相位范围在特定时间段内的变化率；

所述定位参考信号的到达时间，还可以包括达到时间对应的发送时间。
作为本公开的另一种实施例，一种辅助信息发送方法，终端可以作为载波相位参考点确定所述辅助信息，并将所述辅助信息发送至核心网。
例如终端在作为载波相位参考点时，可以自主将所述辅助信息发送至核心网，例如携带在LPP provide location information中携带所述辅助信息发送至核心网。
例如终端在作为载波相位参考点时，核心网可以向终端发送获取所述辅助信息的请求，例如请求携带在LPP location information request中，终端在接收到核心网发送的请求后，将所述辅助信息发送至核心网，例如携带在LPP provide location information中携带所述辅助信息发送至核心网。
需要说明的是，核心网在从所述终端获取到辅助信息后，可以将辅助信息发送给另一个终端，也可以根据需要用作其他用途，本公开并不限制。
