Abstract
Techniques for supporting channel measurement and reporting in a wireless communication system are described. In one design a cell transmits a cell-specific reference signal (CRS) used for channel estimation and coherent demodulation and a channel spatial information reference signal (CSI-RS) used for channel measurement and channel feedback reporting. The cell may transmit the CSI-RS less frequently than the CRS or from more antenna ports than the CRS or on fewer resource elements than the CRS or a combination thereof. In one design a user equipment (UE) determines at least one bandwidth part configured for the UE with each bandwidth part covering at least one subband. The UE receives the CRS and CSI-RS from the cell determines channel feedback information for the at least one bandwidth part based on the CSI-RS sends the channel feedback information to the cell and receives data transmitted by the cell based on the channel feedback information.
