Patent ID: 8265014

Claim:
A method of contention-free multi-channel resource reservation in a wireless mesh network of a plurality of stations, the network using a Multiband Orthogonal Frequency Division Multiplexing Alliance (MBOA) physical layer (PHY) with medium access control (MAC) and Ultrawide band (UWB), said method comprising the acts of: selecting a first channel of a plurality of physical channels in the UWB for negotiation, reservation, and announcement, each of the plurality of stations transmitting and receiving beacons from other stations in a beacon period of the first channel; carrying, in a beacon, reservation information including a start time and a reservation duration; and establishing a channel access reservation by including reservation information in beacon of reserving stations and or more intended receiver stations; and providing the plurality of physical channels, wherein the providing act comprises the acts of: subdividing the UWB into a plurality of bands and a plurality of band groups; and applying time-frequency coding to each of the plurality of band groups wherein the beacons include information elements and make the plurality of stations aware of a reserved channel of the plurality of physical channels and transmission duration, wherein the information elements carry the reservation information including an identification of the reserved channels where a reservation is made, wherein during the beacon period, each station of the wireless mesh network returns to the first channel for exchanging the beacons, and reservations are not allowed during the beacon period, wherein reservation negotiating and announcing only occur in the first channel and does not occur in remaining channels of the plurality of physical channels, and wherein the reservations are valid as long as the reservation information is included in the beacons of the reserving stations and the one or more intended receiver stations.
