Abstract: A multicarrier communication device using orthogonal frequency division multiplexing (OFDM) symbols can vary the number of subcarriers being used on multicarrier communication within a network, based on a predetermined criterion and capability information. The capability information can include a data file, which indicates portions of an electromagnetic spectrum for which regulatory body licenses are currently obtained for a network cell. Alternatively, the capability information can include capability information about the wireless devices in communication with the multicarrier communication device, where the capability information for each wireless device includes device power limitations, device bandwidth width limitations, or which subcarriers a wireless device is capable of using.

Abstract: A multicarrier communication device can vary the number of subcarriers being used to carry on multicarrier communication within a network, based on a predetermined criterion (e.g., traffic load, etc.).

Abstract: Physical layer interface system for use in a broadband wireless access communication network is provided. The broadband wireless access communication network comprises a base station, a subscriber station and a wireless communication link for transmitting wireless communication signals upstream and downstream between the base station and the subscriber station. The physical interface system comprises a first physical layer interface for the base station for processing the communication signals upstream and downstream between the subscriber station and the base station and a second physical layer interface for processing communication signals upstream and downstream between the subscriber station and the base station. The first physical layer interface transmits downstream transmission of communication signals from the base station to the subscriber station in a burst mode.
