Abstract:
Provided is a method for performing channel sensing by a node. The node receives information about a known signal to be transmitted by at least one node of a node group that the node performing the channel sensing belongs to, detects the known signal using the information about the known signal, cancels reception power of the known signal from measured reception power, during a time period in which the known signal is detected, compares remaining reception power except for the reception power with a threshold, and determines whether a channel is occupied or unoccupied according to the comparison. The information about the known signal includes a sequence of the known signal, a power offset between a transmission signal and the known signal during a valid duration of the reception power of the known signal, or a cancellation ratio of reception power of the transmission signal during the valid duration.
