Abstract

本申请公开了一种被用于无线通信的用户、基站中的方法和装置。用户设备接收第一信令，发送第一无线信号。其中，第一信令包括K个第一域和K个第二域，K个第一域分别被用于确定K个第一类向量，K个第一类向量和{K个第二类向量组，K个第二域}分别一一对应；对于每个第二类向量组，其中任一第二类向量和对应的第一类向量之间的相关性与对应的第二域有关；第一无线信号包括第二无线信号和第三无线信号；K个第一类向量和K个第二类向量组分别被用于确定第二无线信号和第三无线信号的多天线相关的发送；第二无线信号和第三无线信号占用相互正交的频域资源。上述方法利用差分方式降低了基于码本的频率选择性预编码传输所需的信令开销。
