Wireless communication device for determining communication pattern
First Claim
1. A wireless communication device, comprising:
- a first wireless communication section for performing first wireless communication using a first frequency band; and
a second wireless communication section for performing second wireless communication using a second frequency band,wherein the second wireless communication section transmits/receives data by the second wireless communication and outputs a communication status signal that represents a signal pattern corresponding to a communication status of the second wireless communication,the first wireless communication section analyzes the pattern of the communication status signal,wherein the communication status signal is a digital signal that is set to a first value during communication and is set to a second value during non-communication, andin case that the communication status signal has not become the first value in a predetermined period, the first wireless communication is not performed;
in case that a total time, during the predetermined period, when the communication status signal has been the first value is a predetermined time or more, the first wireless communication section determines that the second wireless communication is in a congested state;
in case that the same signal pattern based on a period where the communication status signal pattern based on a period where the communication status signal is the first value and a period where it is the second value, has been detected plural times during the predetermined period, the first wireless communication section determines that the second wireless communication is synchronous; and
in the other cases, the first wireless communication section determines that the second wireless communication is asynchronous.

Abstract
In a wireless communication device for performing plural wireless communications with different standards using the same frequency band, degradation of communication quality and communication speed due to communication interference is prevented, while drop in throughput and occurrence of frame loss are prevented. A first wireless communication section first performs wireless communication using a first frequency band and a second wireless communication section performs second wireless communication using a second frequency band with which at least a part of the first frequency band overlaps. The first wireless communication section analyzes a communication status signal which represents a signal pattern corresponding to communication status of the second wireless communication and then determines whether it is synchronous communication, and if it is, the first wireless communication section transmits/receives data in a non-communication period when communication in the synchronous communication is not performed, in synchronization with timing of the synchronous communication.
