Abstract

本申请提供了一种用于传输上行信号的方法和通信装置，以期减小预编码操作的复杂度。该方法包括：终端设备生成并向网络设备发送第一信道信息，该第一信道信息用于指示第一下行信道的相位，该第一下行信道的相位基于对第一下行信道的测量得到，可用于确定第一预编码，该第一预编码用于对第一上行信号的调制符号进行预编码。由此确定的第一预编码为标量，可用于对经调制之后得到的星座图进行预编码，相较于传统的通过对各发射天线端口的信号进行加权处理的预编码操作而言，处理复杂度更低，操作更简单。在相同时频资源上，或，在同一测量范围中存在两个上行信号的传输时，还可以通过分别对该两个上行信号执行上述预编码操作，消除相互间的干扰。
