    • Systems and methods of scheduling sub-carriers in an OFDMA system in which a scheduler takes into account channel conditions experienced by the communication devices to optimize channel conditions. The scheduler can partition a set of sub-carriers spanning an operating bandwidth into a plurality of segments. The segments can include a plurality of global segments that each includes a distinct non-contiguous subset of the sub-carriers spanning substantially the entire operating bandwidth. One or more of the global segments can be further partitioned into a plurality of local segments that each has a bandwidth that is less than a channel coherence bandwidth. The scheduler determines channel characteristics experienced by each communication device via reporting or channel estimation, and allocates one or more segments to communication links for each device according to the channel characteristics.
    • 在OFDMA系统中调度子载波的系统和方法,其中调度器考虑通信设备经历的信道条件以优化信道条件。 调度器可以将跨越工作带宽的一组子载波划分成多个段。 这些段可以包括多个全局段,每个段包括基本上跨整个工作带宽的子载波的不同的非连续子集。 全局段中的一个或多个可被进一步分割成多个本地段,每个本地段具有小于信道相干带宽的带宽。 调度器通过报告或信道估计来确定每个通信设备经历的信道特性,并根据信道特性为每个设备的通信链路分配一个或多个段。
