Abstract
A method for sending a middle pilot is disclosed. The sending method comprises: selecting a middle pilot sequence set; creating a middle pilot subcarrier union; mapping by a base station a middle pilot sequence in the middle pilot sequence set after modulation through an OFDMA or OFDM symbol for transmitting the middle pilot onto a middle pilot subcarrier in a middle pilot subcarrier union corresponding to each transmission antenna, or, mapping by a base station a middle pilot sequence in the middle pilot sequence set through an OFDMA or OFDM symbol for transmitting the middle pilot onto a middle pilot subcarrier in a middle pilot subcarrier union corresponding to each transmission antenna and then performing modulation on the data at the subcarrier. By way of the present invention, the sending of middle pilot sequences is achieved, and the method reduces the periodicity of pilot symbols in the frequency domain and improves downlink performance of user data.
