Method and apparatus for transmitting control information in WLAN system
First Claim
1. A method of signal transmission in a Wireless Local Area Network (WLAN) system, the method comprising:
- generating, by a wireless station, a first very high throughput (VHT) signal containing first control information;
generating, by the wireless station, a second VHT signal containing second control information; and
transmitting, by the wireless station, a physical layer protocol data unit (PPDU) including the first and second VHT signals to at least one target station,wherein the first VHT signal includes an indicator indicating whether the PPDU is a VHT multiple-user (MU) PPDU or a VHT single-user (SU) PPDU.

Abstract
A method and a radio apparatus for signal transmission in a Wireless Local Area Network (WLAN) system are discussed. The method according to an embodiment includes generating first and second very high throughput (VHT) fields including first and second control information, respectively; and transmitting a physical layer protocol data unit (PPDU) including the first and second VHT fields to at least one target station. The first VHT field includes an indicator indicating whether the PPDU is to be transmitted by using a single-user multiple input multiple output (SU-MIMO) scheme or a multi-user multiple input multiple output (MU-MIMO) scheme.
