Techniques enabling dynamic bandwidth reservation in a wireless personal area network

摘要

An embodiment of the present invention provides a method, comprising dynamically reserving free channel time blocks for directional transmissions in a wireless personal area network (WPAN) by a transceiver communicating with a Coordinator and the Coordinator allocating a part or a whole of unreserved channel time blocks for a directional link during a handshake with the transceiver.

主权项

1. An apparatus, comprising:
a transceiver capable of operating in a wireless personal area network, wherein the transceiver is configured to receive, during a first period of a handshake sequence, a request for a reserved time for a directional link in the wireless personal area network, wherein the handshake sequence has a start time corresponding to initiation of the first period; transmit, during a second period of the handshake sequence, using omni-directional transmission, a grant message indicative of a grant of the reserved time for the directional link in response to the request, the second period after the first period; and schedule at least part of the reserved time for other directional links, at least one of the other directional links being non-interfering with the directional link; wherein the request, the grant message, and the reserved time all occur between two consecutive beacons transmitted by the apparatus, and wherein the handshake sequence has an end time prior to a start time of the reserved time.
