TL;DR: A wireless communication method performed by an access point according to an embodiment may include performing channel sounding on a plurality of sub-channels, identifying subchannels selected by stations among the sub-channel, scheduling communications between the AP and the stations based on the selected sub- channels, and transmitting a data frame to the stations through the subchannel based on a scheduling result as discussed by the authors.

TL;DR: In this paper, a channel allocation apparatus in a communication system includes: a measuring unit configured to measure clear channel assessments (CCA) of a plurality of stations (STAs) included in the communication system; a checking unit configured to compare the measured CCAs to a preset reference CCA, and check fairness and unfairness in the STAs; and an allocating unit configured for change and allocation of channels allocated to STAs corresponding to unfairness, according to the measured CCA and the reference CCCA.

TL;DR: In this paper, an operating method of an access point (AP) for a coexistence of basic service sets (BSSs) having different bandwidths is proposed. But the method requires the AP to detect at least one of the BSS signals having a channel bandwidth narrower than the channel bandwidth of the AP, and establish a BSS having the same channel bandwidth as the AP.

TL;DR: In this article, a communication method using interference alignment in a wireless local area network (WLAN) is described, where an access point (AP) according to one embodiment may receive first channel information between a station associated with the AP and the AP, and second channel information from a neighboring AP to perform interference alignment.

TL;DR: In this article, a resource allocation apparatus in a communication system includes an identification unit configured to identify a new frequency band for transmission and reception of data between a plurality of terminals and a first access point, and identify a first frequency band which is being used by a second access point in the new band.
