Method for transmitting control information and apparatus for the same

摘要

A method for transmitting data in a wireless local area network, and a device therefore are discussed. The method according to one embodiment includes generating, by a transmitter, a very high throughput (VHT)-SIG-A field; generating, by the transmitter, a VHT-SIG-B field by applying a single column vector; and transmitting, by the transmitter, a physical layer protocol data unit (PPDU) to a receiver, the PPDU including the VHT-SIG-A field and the VHT-SIG-B field. The single column vector is obtained from a number of spatial streams for the receiver.

1. A method for transmitting data in a wireless local area network, the method comprising:
generating, by a transmitter, a very high throughput (VHT)-SIG-A field including common information, the common information including information about a number of spatial streams used for a receiver; generating, by the transmitter, a VHT-SIG-B field by applying a single column vector and a precoding matrix; and transmitting, by the transmitter, a physical layer protocol data unit (PPDU) to the receiver, the PPDU including the VHT-SIG-A field and the VHT-SIG-B field, wherein the single column vector is obtained from the number of spatial streams indicated by the VHT-SIG-A field.
