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.
摘要翻译：提供了一种无线通信功率控制的系统和方法，其允许调整功率水平，而不需要高带宽用于控制。实施例将副载波分配到不等功率组中，每组具有一致的副载波功率电平。使用来自用户的干扰参数信息，从具有足够功率的组分配子载波以维持用户所需的功率电平。一般来说，具有较高功率要求的用户（例如小区边界附近的用户）将被从具有较高功率级别的组中分配副载波。小区可以使用与邻居不同的分配，使得一个小区中具有最高功率电平的子载波在相邻小区中可能不具有最高功率电平。这种分集可以减少小区边界附近的子载波的小区间干扰，因为相邻基站同时以最高的功率发送两个子载波。
