Abstract:
A method for scanning access points during mobile station's handoff in a wireless communication system, a mobile station for performing the same, a network interface for supporting the same, and a wireless communication system applied with the same are provided to search an access point existing in an available channel during a scanning operation of the mobile station and obtain access point information of the searched access point, thereby minimizing scanning latency. A method for scanning access points comprises the following steps of: transmitting query data to one or more access points(201,202) with respect to a predetermined channel(351); receiving response data to the query data from the access point existing in the channel; request access point information to the access point which has transmitted the response data; and receiving the access point information from the access point(353).
Abstract:
An uplink resource allocation method is provided to transmit an uplink packet by allocating an uplink duration of a PSMP framework every specific period, thereby effectively uplinking a plurality of stations without wasted duration. It is determined whether a packet exists in a service interval of a station(S710). When the uplink packet does not exist, data about the amount of an uplink packet is received from the station(S720). And the uplink is allocated to the service interval every specific period to provided the uplink packet correspondingly to the received data(S740). When it is necessary to provide the uplink packet, the station provides the uplink packet through the uplink allocated to the service interval(S750,S760).
