目前正在研究基于5G NR的非地面通信网络(Non Terrestrial Network，NTN)技术，NTN技术一般采用卫星通信的方式向地面用户提供通信服务，相对于地面蜂窝网络通信，卫星通信不受用户地域的限制，对于一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域，可以通过卫星进行覆盖，并且卫星可以围绕地球做轨道运动，因此，基本上地球上每一个角落都可以被卫星通讯覆盖。Currently, research is underway on 5G NR-based Non-Terrestrial Network (NTN) technology. NTN technology generally uses satellite communications to provide communications services to ground users. Compared with terrestrial cellular network communications, satellite communications are not restricted by user geographic areas. For general terrestrial communications that cannot cover oceans, mountains, deserts and other areas where communications equipment cannot be installed or are not covered by communications due to sparse population, satellites can be used for coverage, and satellites can orbit the earth. Therefore, basically the earth Every corner can be covered by satellite communications.

在卫星通信场景，卫星通常处于高速移动状态，速度可达数公里每秒，且卫星的运动轨道可能椭圆轨道，并且不同终端设备由于所处位置的海拔高度不同，导致卫星和终端之间的距离可能随着时间的变化而快速的变化，如图2所示，因此，终端设备的用于上行发送的定时提前量(Timing Advance，TA)也需要及时调整以适应卫星和终端设备之间的距离的快速变化。In the satellite communication scenario, the satellite is usually moving at a high speed, the speed can reach several kilometers per second, and the orbit of the satellite may be an elliptical orbit, and different terminal devices are located at different altitudes, resulting in the distance between the satellite and the terminal. It may change rapidly with time, as shown in Figure 2. Therefore, the timing advance (TA) of the terminal device for uplink transmission also needs to be adjusted in time to adapt to the distance between the satellite and the terminal device. Rapid changes.

另一方面，由于卫星的高速移动，卫星和终端之间的相对移动速度很高，约几公里每秒，对于网络设备发送的下行信号或终端设备发送的上行信号来说，都具有较大的多普率频偏，利用现有的频偏估计方式，进行频偏补偿，无法有效地补偿，因此，如何进行TA和频偏补偿是一项亟需解决的问题。On the other hand, due to the high-speed movement of satellites, the relative movement speed between the satellite and the terminal is very high, about several kilometers per second. For the downlink signal sent by the network equipment or the uplink signal sent by the terminal equipment, it has a large Doppler frequency offset, using existing frequency offset estimation methods to perform frequency offset compensation, cannot effectively compensate. Therefore, how to perform TA and frequency offset compensation is a problem that needs to be solved urgently.

图3为本申请实施例提供的一种无线通信的方法200的示意性流程图。该方法200可以由图1所示的通信***中的终端设备执行，如图3所示，该方法200可以包括如下至少部分内容：FIG. 3 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the application. The method 200 may be executed by the terminal device in the communication system shown in FIG. 1. As shown in FIG. 3, the method 200 may include at least part of the following content:
