Abstract

SIGNAL TRANSMISSION METHOD AND APPARATUS A signal transmission method and apparatus, capable of determining suitable precoding granularity to enable a balance between a precoding gain and channel estimation performance. The method comprises: a first apparatus determining a first basic parameter set employed for 5 transmitting a signal; the first apparatus determining, according to the first basic parameter set, first precoding granularity employed for transmitting the signal; and using the first precoding granularity to transmit the signal between the first apparatus and a second apparatus. (Fig. 2)
