control at least one of a radio signal transmission operation or a radio signal reception operation of the communication unit;
control at least one of a data transmission operation or a data reception operation in a first operation channel of the plurality of available frequency channels;
control an operation of channel switching among the plurality of available frequency channels at a specific cycle;
determine a first timing of a first notification signal based on the first operation channel, the plurality of available frequency channels, and a beacon interval;
sequentially transmit the first notification signal at the determined first timing, including first information associated with the first operation channel, in a first number of available frequency channels of the plurality of available frequency channels, wherein the first number of available frequency channels excludes the first operation channel;
