Provided is a wireless communication terminal. The processor is configured to receive, from a base wireless communication terminal through the transceiver, a first frame including first information indicating a duration required for a pending frame exchange sequence and second information indicating a frequency band which is allocated for transmission of a second frame, wherein the pending frame exchange sequence is a transmission sequence between one or more wireless communication terminals, set a network allocation vector (NAV) according to the first information indicating the duration for the pending frame exchange sequence, and reset the NAV when the wireless communication terminal does not receive a PLCP Protocol Data Unit (PPDU) for a reference time from a time point at which the first frame is received.
