CPC H04W 72/0446 (2013.01) [H04L 5/0094 (2013.01); H04L 5/0096 (2013.01); H04L 27/26 (2013.01); H04W 72/0453 (2013.01); H04W 74/0816 (2013.01); H04W 84/12 (2013.01)] | 14 Claims |
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 inter-frame space between the first frame and the second frame is short inter-frame space (SIFS) defined in the IEEE 802.11 standard,
wherein the MCS with which the second frame is transmitted is a 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.
