Abstract
A method of reducing interference between two communication systems operating in adjacent frequency bands and coexisting in a communication device is provided, and the two communication systems are a first communication system and a second communication system. The method includes deciding whether to perform an arbitration procedure on a downlink subframe of the first communication system according to a CINR of the first communication system and a RSSI of the second communication system; deciding whether to perform the arbitration procedure on an uplink subframe of the first communication system according to a transmit power of the first communication system and a RSSI value of the second communication system; and when deciding to perform the arbitration procedure on the downlink or uplink subframe, further deciding whether to send a specific packet to request one or more stations not to send packets to the second communication system.
