Abstract
Disclosed is a method for mapping pilot signals in a multiplexing mode of unicast service and Multimedia Broadcast/Multicast Service (MBMS). The method comprises the steps of: generating pilot symbols for the unicast service and the MBMS service, respectively; mapping the pilot symbols for the MBMS service to multiple transmit antennas such that, in a subframe, the pilot symbols for the MBMS service for each antenna are arranged in a same time domain and adjacent to each other, the pilot symbols for the MBMS service for the same transmit antenna are spaced from each other by a predetermined number of subcarriers in the frequency domain and by a predetermined number of OFDM symbols in the time domain, and the pilot symbols for the MBMS service for the same transmit antenna are arranged in a staggered form along the time domain, and mapping the pilot symbols for the unicast service at the same time.
