Abstract

A downlink frame processing system (200) includes a packet switch (608) routing self addressed uplink data (706) from an input port to an output port, a memory (804) coupled to the output port, and a downlink scheduler (802) coupled to the memory (804). The memory (804) includes storage for at least two downlink beam hop locations (302, 304). The downlink scheduler (802) processes from one of a plurality of segments at least one scheduling entry (1312) that includes, for example, a header field (1316) defining at least one of a payload and frame type (1404) for at least one of a payload and frame (1200) to be transmitted, and payload data pointers (1502, 1504, 1506) into the memory (804).
