APPARATUS AND METHOD ADAPTED FOR DIRECTIONAL BANDWIDTH RESERVATION WITH FIXED ANNOUNCEMENT SLOT IN WIRELESS NETWORKS

摘要

An embodiment of the present invention provides an apparatus, comprising a transceiver operable in a wireless personal area network, wherein the transceiver is configured to communicate with a coordinator and at least one receiver and wherein the transceiver and the coordinator use a directional reservation of free channel time blocks using contention-based slots, by selecting uniformly at random contention slots by the transceiver and transmitting a bandwidth reservation request message specifying the requested reservation period using directional transmission pointed towards the coordinator.
