1. A Multicast Broadcast Single Frequency Network (MBSFN) subframe processing method, comprising:
placing, by a base station, an MBSFN Reference Signal (RS) in a 0-filling region of an MBSFN subframe, wherein the 0-filling region of the MBSFN subframe is a time frequency position where 0 is filled in an OFDM symbol adjacent to an MBSFN domain in a non-MBSFN domain; and
transmitting, by the base station, the MBSFN subframe carrying the MBSFN RS.
