通常，基于载波相位carrier phase的定位方法中需要测量和上报的内容包括载波相位的小数部分和整周数。其中，载波相位的小数部分是指不足一整周的小数部分，是接收到的发送机发送的信号的相位测量结果，或根据接收机振荡器产生的基准信号的相位和接收到的发送机发送的信号的相位作差得出的结果。但是，在发送参考信号的过程中，发送机需要将参考信号调制到射频以上，在接收参考信号的过程中，接收机需要解调射频信号，发送机和接收机在处理射频信号的过程中，可能会产生相位误差，该相位误差对定位精度可能会产生影响。本公开，设备间通过将自身在处理射频信号时产生的相位误差信息发送给对端设备，由此，即可根据处理射频信号产生的相位误差，载波相位的小数部分及整周数，进行准确的载波相位定位，从而，提高位置信息的准确性。

其中，TRP侧相位误差group信息可以包括以下至少一项：接收相位误差group信息，发送接收相位误差group信息。相位误差group信息的具体解释，可参见本公开任一实施例的详细描述，在此不在赘述。
其中，测量结果包括载波相位的小数部分及整周数中的至少一项。此外，测量结果还可以进一步包含以下至少一项：参考信号接收功率、到达角(Angle of Arrival)、出发角(Angle of Departure)、到达时间(Time of Arrival)、到达时间差值(Time Difference of Arrival)、往返时间值(Round Trip Time)、接收时间误差(Rx time error group，REG)标识或误差值、发送时间误差(Tx time error group，TEG)标识或误差值，以及发送和接收时间误差(Tx Rx time error group，TREG)标识或误差值。
本公开中，接收相位误差，可以为TRP解调参考信号产生的相位误差，发送接收相位误差可以为TRP调制和解调参考信号时产生的相位误差。其中参考信号可以为用于定位的任意下行参考信号。
本公开中，在基于载波相位进行定位时，接入网设备在对上行参考信号进行测量之后，可以将测量结果发送给核心网设备，由此，核心网设备可以根据测量结果，确定终端设备位置。但是，受TRP在解调接收到的终端设备发送的参考信号时，产生的相位误差的影响，仅根据测量结果，确定终端设备位置不够准确。因此，可以将TRP在解调参考信号产生的相位误差对应的group信息，作为测量结果对应的TRP侧相位误差group信息，发送给核心网设备，从而，核心网设备可以根据该group信息，确定接入网设备在获得测量结果时，TRP解调参考信号时所产生的相位误差，并根据此相位误差及对应的测量结果，确定终端设备的位置，从而可以提高定位的准确性。
本公开中，接入网设备可以向核心网设备发送包括测量结果及每个测量结果对应的TRP侧相位误差group信息，之后，核心网设备可以根据该相位误差group信息，确定TRP在获得测量结果时，解调参考信号所产生的相位误差，并根据此相位误差，及对应的测量结果，确定终端设备的位置，从而提高了定位的准确性。

可选的，不同类型的参考信号，对应的TRP侧相位误差group信息可以不同，比如，参考信号为下行参考信号时，TRP侧相位误差group信息可以为TRP侧的发送相位误差group信息，和/或，发送接收相位误差group信息。
本公开中，发送相位误差，可以为TRP调制参考信号时产生的相位误差，接收相位误差可以为TRP解调参考信号产生的相位误差，发送接收相位误差，可以为TRP调制和解调参考信号时产生的相位误差。
本公开中，在基于载波相位进行定位时，包括接入网设备发送下行参考信号，终端设备接收下行参考信号并测量。其中，接入网设备在将下行的参考信号调制成射频信号后，会产生相位误差。因此，可以将接入网设备在调制参考信号过程中产生的相位误差对应的相位误差group信息，作为该参考信号对应的接入网设备侧相位误差group信息，发送给核心网设备，之后，核心网设备可以将该相位误差group信息，发送给终端设备，由此，终端设备，即可确定发射接收点在调制参考信号所产生的相位误差，并根据此相位误差，及该参考信号的测量结果，确定终端设备的位置，从而可以提高定位的准确度。

本公开中，步骤1101的具体实现过程，可参见本公开中任一实施例的详细描述，在此不再赘述。
步骤1102，响应于相位误差group信息为相位误差组ID,向核心网设备发送每个相位误差group ID对应的误差值。
本公开中，当相位误差group信息为相位误差group ID时，TRP还可以将每个相位误差group ID对应的误差值发送给核心网设备。由此，核心网设备可以根据相位误差group ID，确定group对应的误差值，并根据此相位误差，及测量结果，确定终端设备的位置，从而可以提高定位的准确性。
需要说明的是，接入网设备向核心网发送了相位误差group ID后，也可以不单独指示每个该相位误差group ID对应的误差值，核心网设备根据协议约定，确定该相位误差group ID对应的误差值，本公开对此不做限定。
