Claim:
1. A method for calculating channel quality indication information, comprising: performing, by a user equipment (UE), a channel measurement based on a received Channel-State Information-Reference Symbol (CSI-RS) or a cell-specific reference signal (CRS), determining, by the UE, a channel state information (CSI) reference source and calculating a CQI value corresponding to said CSI reference resource and channel quality indicator (CQI) calculation conditions, and thereafter calculating, by the UE a CQI value corresponding to said CSI reference resource said determined conditions and according to a measurement result; wherein, said determined CQI calculation conditions comprises: regardless whether a current sub-frame is a multicast broadcast-single frequency network (MB-SFN) subframe or non-MBSFN subframe, when said UE calculates said CQI, said UE calculates a CRS overhead of said current subframe in accordance with said non-MBSFN subframe.
