Document Type and Number:

WIPO Patent Application WO2006013531

Kind Code:

A3

Abstract:

The system and method of the present invention provide a protocol for a device (400) to announce that a previously reserved time-period or time-slot is not (completely) used and becomes available, so that other devices can transmit during the unused time. The system and method are especially intended for systems with distributed medium reservation by the devices, i.e., those systems adhering to a distributed reservation protocol (DRP).
