Abstract:
1. A method for communication by a base station in an Orthogonal Frequency Division Multiple Access (OFDMA) communications system comprising a plurality of base stations and mobile stations, the base station serving a cell among a plurality of cells, the method comprising: operating in a plurality of noncontiguous useable frequency subbands useable for simultaneously transmitting signals to mobile stations in the cell, wherein a primary control signal of the signals is being transmitted via one or more orthogonal frequency division multiplexing (OFDM) symbols in at least one subframe over each of the plurality of noncontiguous useable frequency subbands; indexing the plurality of noncontiguous useable frequency subbands as contiguous subbands; and sending to the mobile stations in the cell the indices of the plurality of noncontiguous useable frequency subbands via a control message.
