US 10,257,837 B2 · Method for transmitting frame in wireless LAN system

Abstract

The present invention relates to a method for transmitting a frame in a wireless communication system, in particular, a high density wireless LAN system, and a station apparatus for performing the same. To this end, a station for transmitting a frame configures a radio frame for a second type station, including a frame part for a first type station and a frame part for the second type station, wherein the frame part for the second type station includes a first signaling field (SIG A) for the second type station and a second signaling field (SIG B) for the second type station. The SIG A for the second type station includes modulation and coding scheme (MCS) information applied to the SIG B for the second type station, and the MCS level applied to the SIG B for the second type station supports an MCS having level than the lowest MCS level defined for the first type station.

A method for transmitting a radio frame by a second type station (STA) in a wireless local area network (WLAN) system, the method comprising:

configuring the radio frame including a first part for a first type STA and a second part for the second type STA,
wherein the second part comprises a first signaling field;
and
and a second signaling field
transmitting the configured radio frame via a bandwidth equal to or greater than 80 MHz,
wherein configuring the radio frame comprises:
processing information for at least one of the first signaling field or the second signaling field for a first 20 MHz of the bandwidth;
and
duplicating the information processed for the first 20 MHz into a second 20 MHz within the bandwidth,
wherein processing the information comprises:
encoding and modulating the information according to a lowest MCS (Modulation and Coding Scheme) level among available MCS levels,
wherein the lowest MCS is used for BPSK (Binary Phase Shift Keying) with a ½ coding rate;
and
repeating the information in a unit of N bits,
wherein N is integer greater than 1.
