1. A method of signal transmission in a Wireless Local Area Network (WLAN) system, the method comprising:
- generating, by a station, a first very high throughput (VHT) signal containing control information;
generating, by the station, a second VHT signal containing control information; and
transmitting, by the station, the first VHT signal and the second VHT signal, wherein when the second VHT signal is generated for a single target station the second VHT signal is transmitted to the single target station, wherein when the second VHT signal is generated for a plurality of target stations the second VHT signal is transmitted to the plurality of target stations, and wherein the first VHT signal includes an indicator indicating that the second VHT signal 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.

Abstract
There is provided a method of transmitting control information in a Wireless Local Area Network (WLAN) system, comprising transmitting first control information by means of cyclic shift delay diversity beam-forming and transmitting second control information. The first control information comprises information necessary for each of a plurality of target stations of the second control information to receive the second control information. The second control information beamformed and transmitted to the plurality of target stations.
