Claim:
A method of reserving bandwidth for disjoint time intervals in a wireless network, the method comprising: transmitting a first control packet comprising parameters for a disjoint network allocation vector (NAV), the parameters indicative of a plurality of disjoint time blocks during which transmissions by one or more other devices in the wireless network are to be deferred, wherein the parameters indicative of the plurality of disjoint time blocks include a plurality of time durations of the disjoint time blocks, a total number of periodic time blocks, and a plurality of time intervals between two consecutive disjoint time blocks, wherein the plurality of disjoint time blocks include: at least one beacon protection time block during which a beacon for a superframe is transmitted, and a first time duration, a time interval between two consecutive disjoint time blocks, and a second time duration, wherein the beacon is transmitted during the second time duration; setting the disjoint NAV; deferring transmissions of data packets during one or more of the plurality of disjoint time blocks; and clearing the disjoint NAV if a message indicative of the disjoint NAV is not received for a particular period.
