Data processing method and base station for downlink transmit diversity

摘要

A data processing method and a base station for downlink transmit diversity are disclosed. The method comprises: obtaining data symbol groups formed by arranging a first type data symbol and a second type data symbol in an interval, wherein the first type data symbol is more important; determining a first antenna port paring mode corresponding to a current slot; performing, for OFDM symbols including reference signals in the current slot, an antenna port and subcarrier mapping on symbols in a transmit diversity matrix corresponding to the data symbol group according to the first antenna port paring mode, wherein a subcarrier in which a symbol related to the first type data symbol is located is nearer to a subcarrier in which a reference signal at the same antenna port is located; and performing an inverse fast fourier transform and a cyclic prefix insertion processing on symbols mapped to subcarriers and then mapping the symbols to a physical antenna for transmission. According to the invention, comparatively important symbols may obtain better protection.
