Abstract
Embodiments provide a signal transmission apparatus and a downlink signal transmission method. A downlink common channel signal that needs to be sent by using a wide beam is divided into multiple groups of grouped signals; for each group of grouped signals, signal weighting is separately performed on different radio frequency paths in a multi-antenna system; weighted grouped signals are combined to obtain a weighted downlink common channel signal; and the weighted downlink common channel signal is transmitted.
