Abstract

Official abstract text for this publication.

A method for automatically detecting a packet mode in a wireless communication system supporting a multiple transmission mode includes: acquiring at least one of data rate information, packet length information and channel bandwidth information from a transmitted frame; and determining the packet mode on the basis of the phase rotation check result of a symbol transmitted after a signal field signal and at least one of the data rate information, the packet length information and the channel bandwidth information acquired from the transmitted frame.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of transmitting control information in a wireless communication system, comprising: transmitting a first modulation sequence in a first orthogonal frequency division multiplexing (OFDM) symbol; transmitting a second modulation sequence in a second OFDM symbol; and transmitting a third modulation sequence in a third OFDM symbol, wherein a constellation for the third modulation sequence is rotated by 90° counter-clockwise relative to a constella…
