1. A wireless communication terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to:
receive, from a base wireless communication terminal through the transceiver, a first frame including a duration field indicating a duration required for a pending frame exchange sequence and first 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 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 set based on a Modulation & Coding Scheme (MCS), with which the second frame is transmitted, an inter-frame space between the first frame and the second frame, and a Slot Time defined in an IEEE 802.11 standard,
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,
wherein the second frame is a response to the first frame.
