Abstract

A wait-time acquisition unit measures a wait time before transmission of data in an exposed terminal, and an interference-amount inferring unit infers the amount of interference in the exposed terminal based on the wait-time information. A channel-utilization calculation unit calculates an amount of channel utilization based on the inferred amount of interference. A call admission controller controls call admission based on the amount of channel utilization that is considered with the amount of interference in the exposed terminal.

Description

technical field [0001] The present invention relates to an interference amount estimating device and method, and more particularly to an interference amount estimating device and method for estimating an interference amount from another terminal in wireless communication. Also, the present invention relates to a communication system and a control method thereof, and particularly to a radio system and a control method thereof that perform control based on an estimated amount of interference. Background technique [0002] Wireless communications such as wireless LANs are becoming popular. In a wireless LAN, a wireless link is established between an access point and a terminal to transmit and receive data (data group). In wireless communication, because wireless signals are used in data transmission and reception, it is difficult to completely eliminate interference between wireless signals, and once interference occurs, there is a problem of degradation in communication quali...
