1. A wireless communication terminal comprising:a transceiver; and
wherein 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 and the base wireless communication terminal,
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,
wherein the reference time is determined based on a Modulation & Coding Scheme (MCS) with which the second frame is transmitted,
wherein the MCS with which the second frame is transmitted is the most robust MCS usable for a transmission of a PPDU including the second frame, and
wherein the second frame is a response to the first frame.
