Abstract:
Provided is an access point (AP) for providing wireless communication to a plurality of stations (STAs), the AP including a type determiner to determine a type of each of the plurality of STAs, and an association identification (AID) allocator to allocate AIDs to the plurality of STAs, respectively, based on the determined type such that AIDs corresponding to an identical type among the allocated AIDs are clustered.
Abstract:
Provided is a method of transmitting and receiving a frame for a multi-user multiple-input and multiple-output (MU-MIMO) communication in an access point (AP), the method including determining at least one transmission station (STA), transmitting, to the transmission STA, an uplink multi-user poll (UL MU poll) frame requesting a data frame, receiving the data frame from the at least one transmission STA simultaneously, and transmitting an acknowledgement (ACK) frame to the at least one transmission STA in response to the receiving.
Abstract:
Provided is a method and apparatus for reducing wireless traffic by controlling a management frame of an access point (AP) in a wireless local area network (WLAN), the AP including a beacon frame generator to generate a beacon frame, a probe response generator to generate a probe response frame, and a management frame control unit to control at least one of a period of the beacon frame and a number of retransmissions of the probe response frame, based on at least one of a power consumption of the AP, a system load imposed on a system including the AP, and an emergency level related to whether an emergency occurs.

Abstract:
A scanning method in a wireless local area network (WLAN) system is provided. The scanning method includes transmitting, by a station, a probe request frame and receiving, by the station, a probe response frame from an access point (AP). The AP determines whether to transmit the probe response frame in response to the probe request frame using information indicated by the probe request frame.
Abstract:
A method and user terminal for dynamically controlling routing are provided. The method may provide an effective routing mechanism in a system to which a plurality of radio access technologies (RATs) are applied. The method may perform routing based on characteristics of the RATs, a degree of a generated traffic load, a user preference of a RAT, and the like.
Abstract:
A scanning method in a wireless local area network (WLAN) system is provided. The scanning method includes transmitting by a station a probe request frame via a channel, and receiving by the station a probe response frame from a target access point (AP) to respond to the probe request frame. The probe request frame includes at least one of information regarding a response reception time and preference information regarding the target AP.
Abstract:
Provided is an interference avoidance-based communication apparatus and method, the apparatus including an interface to receive operating channel number information transmitted by another communication apparatus in response to an event occurring in the other communication apparatus, and a processor to verify a current use channel of the other communication apparatus based on the received operating channel information, allocate a first weighted value to a remaining channel, aside from the verified current use channel and a second weighted value to the verified current use channel, and generate channel map information for use in hop selection based on the remaining channel to which the first weighted value is allocated and the current use channel to which the second weighted value is allocated.
