Communication device and method of determining communication method

摘要

A communication device and a communication scheme judgment method that enable reception of frames of different communication schemes without setting a common synchronization signal in the frames for each communication scheme. A signal including synchronization information corresponding to a communication scheme is receivable via a frequency band within which a frequency band of a channel corresponding to a first communication scheme overlaps with at least a portion of a frequency band of a channel corresponding to a second communication scheme. Using the synchronization information, when synchronization of one communication scheme out of the first communication scheme and the second communication scheme is establishable, processing of the signal is performed using the one communication scheme, and when the synchronization of the one communication scheme is not establishable and synchronization of the other communication scheme is establishable, processing of the signal is performed using the other communication scheme.

主权项

1. A communication device that receives, via a communication network, a plurality of signals each corresponding to one of a first communication scheme and a second communication scheme, wherein
each signal of the plurality of signals includes synchronization information corresponding to one of the first communication scheme and the second communication scheme, the communication device comprising: a non-transitory memory storing a program; and a hardware processor that executes the program and causes the communication device to operate as: a receiver configured to receive the plurality of signals via a frequency band within which at least a portion of a frequency band of a channel corresponding to the first communication scheme overlaps with at least a portion of a frequency band of a channel corresponding to the second communication scheme; a synchronization judgment unit that detects the synchronization information included in the signal received by the receiver; and a scheme judgment unit that, when synchronization information corresponding to the first communication scheme is detected in the signal received by the receiver, performs reception processing of the signal using the first communication scheme, and when synchronization information corresponding to the first communication scheme is not detected and synchronization information corresponding to the second communication scheme is detected in the signal received by the receiver, performs reception processing of the signal using the second communication scheme.
