TLDR
In this paper, a multi-coexistence communication system based on an interference-aware environment and a driving method is provided to recognize a situation about interference using an interference temperature limit value, thereby transmitting the signal after removing the interference value from a transmission signal.
Abstract: 
PURPOSE: A multi coexistence communication system based on an interference-aware environment and a driving method thereof are provided to recognize a situation about interference using an interference temperature limit value, thereby transmitting the signal after removing the interference value from a transmission signal. CONSTITUTION: A sub base station(200) generates a sub transmission signal by itself. The sub base station inputs a frequency bandwidth and an interference temperature limiting value. The sub base station determines frequency usage capacity according to the inputted interference temperature limiting value. The sub base station assigns the frequency bandwidth of a sub communication terminal(400) in the determined capacity.

Method for efficient channel use

Junho Jo, +1 more
TL;DR: In this paper, a channel use method for efficient channel use is disclosed, which may comprise the steps of: selecting a specific channel from channels configured to be shared along with a homogeneous or heterogeneous communication scheme; and performing an interference avoidance procedure if the selected channel interferes with a neighboring access point.

Method for providing information such that different types of access points can coexist

Junho Jo, +1 more
TL;DR: In this paper, a method for providing information for enabling different types of access points to coexist is proposed, which includes: receiving frequency information for broadcasting from a broadcast database server, obtaining information regarding different types OFAs located in a certain area, generating information regarding one or more frequency bands that may be used by the different OFAs, and transmitting information regarding the available frequency bands to the different AFAs.
