Description

数据传输方法及装置、存储介质 技术领域
本公开涉及通信领域，尤其涉及数据传输方法及装置、存储介质。
背景技术
在无线通信技术的研究中，卫星通信被认为是未来无线通信技术发展的一个重要方面。卫星通信是指地面上的无线电通信设备利用卫星作为中继而进行的通信。卫星通信系统由卫星部分和地面部分组成。卫星通信的特点是：通信范围大；只要在卫星发射的电波所覆盖的范围内，从任何两点之间都可进行通信；不易受陆地灾害的影响(可靠性高)。卫星通信作为目前地面的蜂窝通信系统的补充，可以有以下的好处：首先，可以实现延伸覆盖，对于目前蜂窝通信系统无法覆盖或是覆盖成本较高的地区，例如海洋，沙漠，偏远山区等，可以通过卫星通信来解决通信的问题。其次，可以进行应急通信，例如在发生灾难如地震等的极端情况下导致蜂窝通信的基础设施不可用的条件下，使用卫星通信可以快速的建立通信连接。另外还可以提供行业应用，例如对于长距离传输的时延敏感业务，可以通过卫星通信的方式来降低业务传输的时延。
可以预见，在未来的无线通信系统中，卫星通信系统和陆地上的蜂窝通信系统会逐步的实现深度的融合，真正的实现万物智联。
在目前的陆地通信系统中，一般数据的传输都是基于调度的，也就是说基站通过调度指令在指示的时频资源位置上指示终端进行数据的发送或是接收。或者，基站还可以预先配置终端进行数据发送或是接收的资源，终端基于配置信息在对应的时频资源位置上进行数据的发送或是接收。
但是，对于某些终端来讲，受限于终端的能力，只能支持半双工的传输方式。即在一个时间单元上要么进行下行数据接收，要么进行上行数据发送，不能同时进行数据接收和数据发送。但是，在NTN(Non-terrestrial Network，非地面网络)的场景下，受限于传播时延的存在，卫星可能无法准确知道终端的下行链路和上行链路的定时，因此可能存在终端收到针对下行接收和上行发送的调度，指示终端在至少一个时间单元上同时进行上行和下行的传输的情况。
