RESOURCE MAPPING METHOD, BASE STATION AND USER EQUIPMENT

摘要

Disclosed are a resource mapping method, a base station and a user equipment. The method comprises: determining a physical downlink shared channel resource element mapping and quasi-colocation (PQ) parameter set of a user equipment, the PQ parameter set comprising a parameter of a resource element (RE) occupied by a cell-specific reference signal (CRS) and/or a demodulation reference signal(DMRS), the parameter of the RE occupied by the CRS comprising at least one of the following: a parameter of a subframe occupied by the CRS, a parameter of a frequency band occupied by the CRS in the subframe and the type of a carrier bearing the CRS (110); and sending the PQ parameter set to the user equipment (120). Using the present invention enables the user equipment to correctly recognize the RE bearing the CRS and/or the DMRS in the network environment of a new carrier type and/or a new LTE protocol version, and to further determine the RE used for data transmission, thereby enabling normal communication between the base station and the user equipment, and improving the user experience.
