Abstract:
A method and apparatus for signal transmission in a Wireless Local Area Network (WLAN) system. The method according to one embodiment includes generating a first very high throughput (VHT) signal, generating a second VHT signal, and transmitting the first VHT signal and the second VHT signal. 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. The first VHT signal and the second VHT signal are used to transmit control information, and the control information includes a modulation and coding scheme (MCS) index indicating an MCS used in the step of transmitting and further includes a spatial stream identifier indicating a number of spatial streams.
