<p><P>PROBLEM TO BE SOLVED: To carry out MAC processing for efficient use of a high throughput system that is backward compatible with an existing system. <P>SOLUTION: In one aspect, a data transmission structure comprises consolidated polling and one or more frames transmitted in accordance with the consolidated polling. In another aspect, a Time Division Duplexing (TDD) data transmission structure comprises a pilot, consolidated polling, and zero or more access points to remote station frames in accordance with the consolidated polling. 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)2010,JPO&INPIT</p> |
