摘要
A method for tessellating a subframe using maximal-sized bricks. A brick bandwidth and a brick time duration are computed based on the heights and widths of the bursts in the subframe. Bursts within the brick-tessellated subframe are referenced using a brick-based coordinate system in which burst location and size are specified in units of bricks. A method for assembling and disassembling brick-based superframes is also disclosed. Bricked-based superframes are assembled and disassembled using a Superframe Preamble, a Superframe Control Header (SFCH), a Superframe Downlink Map (SDL- MAP), a Superframe Uplink MAP (SUL-MAP) and brick-structured downlink and uplink frames.
