A method and apparatus for performing resource allocation with lower required overhead is provided herein. Resource allocations for data transmissions are chosen in such a way as to provide channel quality information for various parts of the channel bandwidth (frequency selective channel quality information), such as allocating two different resource blocks (on different sets of subcarriers) to a mobile unit for two different transmissions. These data transmissions are used to estimate frequency selective channel quality information, thereby eliminating or greatly reducing the need for channel sounding with a broadband pilot. As a result, the overhead on the uplink of the communication system may be significantly reduced.
