Disclosed are a method and system for configuring a Physical Multicast Channel (PMCH), a method and system for acquiring a PMCH configuration and a method and system for sending and receiving subframes based on the PMCH configuration. The configuration method includes the following step: a base station configuring information for the PMCH or a Multimedia Broadcast and Multicast Service (MBMS) through a high-layer signalling and/or a predefinition and/or a Multicast Control Channel (MCCH). The configured information is at least one of a transmission band, a frequency-domain location, an initial location of an Orthogonal Frequency Division Multiplexing (OFDM) symbol of the PMCH, a transmission subframe cluster of the PMCH, a number of transmission layers or used port indexes and a number of ports of the PMCH and MBMS reference signal pattern information.
