<p><P>PROBLEM TO BE SOLVED: To provide MAC processing for efficient use of high throughput systems. <P>SOLUTION: MAC processing may maintain backward compatibility with various types of legacy systems. In one aspect, a data transmission structure comprises a consolidated poll and one or more frames transmitted in accordance with the consolidated poll. In another aspect, a Time Division Duplexing (TDD) data transmission structure comprises a pilot, and zero or more access points to remote station frames in accordance with the consolidated poll. In one aspect, frames are transmitted sequentially with no or substantially reduced interframe spacing. In another aspect, a guard interframe spacing may be introduced between frames transmitted from different sources, or with substantially different power levels. In another aspect, a single preamble is transmitted in association with one or more frames. In another aspect, a block acknowledgement is transmitted subsequent to the transmission of one or more sequential frames. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
