    摘要: Systems and methods are disclosed for transporting data across an air interface using a blending of protocol layers to achieve reduced bandwidth. Advantage is taken of the fact that the extra overhead from, for example, the Ethernet protocol is addressing information pertaining to the destination of the packet. This destination information (for example, the Ethernet address) can be stripped from the transmission prior to the air interface and recreated after the air interface. In one embodiment, the concepts of a proper Layer 2 CS are merged on top of the 802.16 protocol and still retain the benefits of a Layer 2 transparent bridged service layer to the network layer. In one embodiment, the MAC address of the destination is used for the air interface and the Ethernet address is recreated and added on the far side of the air interface.

    摘要: A system and method of wireless communication power control is provided which allows for adjusting power levels without requiring high bandwidth for control. Embodiments allocate subcarriers into unequal power groups, each group having a consistent subcarrier power level. Using interference parameter information from a user, a subcarrier is assigned from a group having adequate power to maintain the user's required power level. In general, users with higher power requirements, such as those near cell boundaries, will be assigned subcarriers from a group having a higher power level. A cell may use a different allocation than a neighbor, so that subcarriers with the highest power level in one cell may not also have the highest power level in a neighboring cell. Such diversity may reduce inter-cell interference of the subcarriers near a cell boundary, since no two subcarriers are transmitted with highest power simultaneously by neighboring base stations.

    摘要: Systems and methods for intelligently switching between communication modes. An optimum communication mode is selected based upon determining the mobility of the subscriber station, the location of the subscriber station, and orthogonality of signals received from the subscriber station with respect to a signal of another subscriber station. Each determination may be continually or incrementally performed according to the passage of a time interval or upon observation of changes in relevant conditions.
