Abstract:
1. A method for processing reference symbols, comprising: configuring, by a transmitting end, a reference symbol structure for a downlink subframe according to a number of deployed antennae; inserting, by the transmitting end, common reference symbols and user-specific reference symbols to be transmitted into the downlink subframe according to the reference symbol structure, transmitting the common reference symbols and the user-specific reference symbols; and transmitting reference symbol indication information, wherein the reference symbol indication information comprises information about the reference symbol structure, the number of antennae and a distribution of the user-specific reference symbols within the downlink subframe, wherein the transmitting end transmits the information on the reference symbol structure and the number of antennae through broadcasting: and the transmitting end determines whether the information on the distribution of the user-specific reference symbol within the downlink subframe is maintained unchanged within a preset time period or a preset number of frames; and if the information on the distribution of the user-specific reference symbol within the downlink subframe is maintained unchanged within the preset time period or the preset number of frames, the information on the distribution is transmitted through broadcasting; otherwise, the information on the distribution is transmitted through control signaling.
