IN ONE OR MORE NETWORK COEXI STABLE ENVIRONMENT, A METHOD FOR DETERMINING WHETHER A SPECIFIC CHANNEL IS AVAILABLE OR NOT, A METHOD FOR RECEIVING A SIGNAL FOR DETECTING AND A METHOD FOR COMMUNICATING IN COEXISTENCE WITH A DIFFERENT KIND OF NETWORK

摘要

Network communication and more particularly a method for determining whether a specific channel is available or not in an environment a plurality of networks can coexist are disclosed. In addition, a method for increasing a range for detecting a signal of a different type of network using a signal composed of a narrowband signal as a signal for detecting the different type of network is disclosed. Furthermore, a method for performing communication in an environment in which one or more communication networks and more particularly different types of networks coexist is disclosed.
