Abstract: 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.

Abstract: An apparatus and method for transmitting and receiving data, wherein retransmissions of information can be a different size from the initial transmission. The invention utilizes a partial Chase encoder 306 to truncate or expand data depending on the availability of channel resources for retransmission. A partial Chase combiner 314 processes the received demodulated data based solely on the number of codes and modulation received (i.e., predetermined, with no additional signaling required). If the received retransmission is smaller than the first transmission, only a portion of the soft bits are combined. If the retransmission is larger than the first transmission, some values of the stored first transmission are combined with more than one received soft bit in the retransmission.

Abstract: In a multi-carrier communication system employing adaptive modulation and coding, a receiver feeds back channel quality information for a “binned” group of subcarriers instead of sending an individual quality report for each subcarrier. A transmitter will utilize the channel quality information for the bin to determine a set of γeff values corresponding to a set of modulation and coding scheme candidates, where γeff is an effective SNR that would yield a same FER in an AWGN channel. The transmitter utilizes the set of γeff values to aid in determining a modulation and coding scheme, and determine a single modulation and coding scheme for all subcarriers within the channel.
