Abstract

本申请提供了一种信号传输的方法和基站，该方法包括：基站确定将在第一载波上的第一小区中发送的第一载波信号和将在第二载波上的第二小区中发送的第二载波信号；该基站将该第一载波信号和该第二载波信号映射到RRU的N个物理端口，使得在同一个正交频分复用OFDM符号内，该第一载波信号中用于传输导频的类型Type B符号和该第二载波信号中用于传输导频的Type B符号映射到不同物理端口，且该N个物理通道中每个物理通道发送的信号的总功率不大于该RRU的额定功率；该基站通过该N个物理端口发送该第一载波信号和该第二载波信号。采用本申请提供的方法和基站，能够提高射频通道的输出功率，从而提高功率利用率。
