Techniques for sending feedback information in a wireless communication system are described. In one design, precoding control indication (PCI), rank, and channel quality indication (CQI) for data transmission from a transmitter to a receiver may be determined by evaluating different hypotheses. A report may be formed based on the PCI, rank and CQI. The PCI may include a precoding matrix or vector to use for the data transmission. The CQI may include at least one CQI value for at least one transport block to send for the data transmission. The rank and CQI may be combined based on a mapping. For example, the CQI may include one CQI value and fall within a first range of values if one transport block is preferred by the receiver. The CQI may include two CQI values and fall within a second range of values if two transport blocks are preferred.
