Abstract
Techniques for supporting channel measurement and reporting in a wireless communication system are described. In one design, the 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. A cell may transmit CSI-RS less frequently than CRS, or from more antenna ports than CRS, on fewer than the CRS resource elements, or a combination thereof. In one design, the user equipment (UE) determines at least one bandwidth portion configured for the UE, and each bandwidth portion covers at least one subband. The UE receives the CRS and the CSI-RS from the cell, determines the channel feedback information for the at least one bandwidth portion based on the CSI-RS, transmits the channel feedback information to the cell, And receives the data transmitted by the terminal.
