    Abstract: A method and apparatus for subcarrier selection for systems is described. In one embodiment, the system employs orthogonal frequency division multiple access (OFDMA). In one embodiment, a method for subcarrier selection comprises a subscriber measuring channel and interference information for subcarriers based on pilot symbols received from a base station, the subscriber selecting a set of candidate subcarriers, providing feedback information on the set of candidate subcarriers to the base station, and receiving an indication of subcarriers of the set of subcarriers selected by the base station for use by the subscriber.

    Abstract: A method and system for partitioning frames into sub-frames, where the frames may be defined according to a reference system standard, and transmitting one or more sub-frames during a pre-designated downlink transmission, and transmitting one or more sub-frames during a pre-designated uplink transmission. A method and system for partitioning frames into sub-frames, transmitting one or more sub-frames including a legacy preamble for communicating with a legacy terminal operating according to a reference system standard during a pre-designated legacy transmission period, and transmitting sub-frames including a supplemental preamble for communicating with a non-legacy terminal operating according to the evolved version of the reference system standard during a pre-designated non-legacy transmission period. A method and system for partitioning each of two or more frames into two or more sub-frames and transmitting the sub-frames for a non-relay transmission including transmitting a (DL:BS→MS/RS) sub-frame during a pre-designated downlink transmission and a (UL:MS/RS→BS) sub-frame during a pre-designated uplink transmission, and transmitting sub-frames for a relay transmission including transmitting a (DL:RS→MS) sub-frame during a pre-designated downlink transmission and a (UL:MS→RS) sub-frame during a pre-designated uplink transmission.
