Claim Text:
1. An apparatus for channel sensitive scheduling in a communication system including a plurality of sub-carriers spanning an operating frequency band, the apparatus comprising: a channel estimator executably configured to determine a channel estimate corresponding to each of a plurality of segments spanning the operating frequency band based on pilot signals, each of the plurality of segments having a bandwidth less than a total bandwidth; a signal mapper executably configured to map data symbols to a subset of the plurality of sub-carriers in the communication system; a scheduler coupled to the channel estimator and executably configured to determine a first preferred segment based on the channel estimates and user data constraints of data to be transmitted, determine a number of sub-carriers assigned to the subset of the plurality of subcarriers based on one or more signal conditions, select the subset of the plurality of sub-carriers from within the first preferred segment, and further executably configured to control the signal mapper to map the data symbols to the subset of the plurality of sub-carriers; and a Channel Quality Indicator (CQI) receiver coupled to a receiver module and executably configured to process channel characteristic reporting messages received by the receiver module to determine a second preferred segment and further configured to generate a resource assignment message based on the channel characteristic reporting messages.
