Abstract
A method of measuring a state of a plurality of channels is provided. The method includes transmitting to a second device test signal information needed to transmit/receive a test signal for measuring the state of the plurality of channels; receiving an information received response from the second device, indicating that the second device has received the test signal; if the information received response is received, transmitting the test signal to the second device, using the test signal information, via the plurality of channels; and receiving from the second device the state information regarding the plurality of channels which has been measured by using the test signal.
Claims11
A method of selecting an idle channel from among a plurality of idle channels for communication between a first device and a plurality of second devices, the method comprising:
- setting a priority for respective idle channels from among the plurality of idle channels, using at least one of:
- distance information regarding a distance between the first device and the respective second devices;
- preference information for an idle channel of the respective second devices;
- and
- application information regarding an application provided by the respective second devices;
- and
- selecting the idle channel for communication with the plurality of second devices using the set priority.
