Patent ID: 7616602

Claim:
A time division-based wireless local area network (LAN) communication method using an access point (AP) in an infrastructure mode, comprising, on the AP's side: receiving a time slot allocation request frame from a station; allocating time slots during which the station can transmit data based on the time slot allocation request frame; broadcasting reservation information on said allocated time slots; and readjusting said time slot allocation and broadcasting new adjusted reservation information, when no data transmission is made during a predetermined time, wherein, when the AP allocates said time slots, a minimum interval between said time slots is added to the time slots so as to allow time synchronization function (TSF) of the IEEE 802.11 wireless LAN to be maintained, in order to avoid data collision between the time slots, and wherein the minimum interval is added to the time slots such that data collision between the time slots is avoided, wherein the AP manages a list of stations authorized for access, and wherein the AP allocates said time slots only when the station having transmitted the time slot allocation request frame is included in the list.
