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.

Abstract: A base station (101) will request the transmission of quality information from a particular remote stations (102, 103) only when data is queued to be transmitted to the remote stations. Once a remote station begins the transmission of channel quality information, the transmission of such information continues until the data transmission is successfully delivered to the remote station. The base station receives the channel quality information and adjusts the modulation and coding of the remote stations accordingly. Where data is transmitted simultaneously to a plurality of remote stations, a set of queues (303) for the multiple remote stations is maintained, and based on queue status, a channel quality request messages is sent to a sub-set of remote stations with data queued.

Abstract: Narrowband remote units will scan over frequencies within a wideband channel spectrum, evaluating frequency-selective channel characteristics. The best sub-channel(s) for communication will be determined and reported back to a base station via a channel-quality report message. The base station will then utilize only a narrowband portion (e.g., one sub-channel comprised of a plurality of OFDM subcarriers) of the wideband channel for transmitting data to the narrowband unit.
