METHOD FOR TRANSMITTING AND RECEIVING SIGNAL IN WIRELESS LAN AND APPARATUS THEREFOR
First Claim
1. A method for receiving a signal by a station (STA) in a wireless local area network (LAN) system, the method comprising:
- receiving a multi-user (MU) frame including a signal-A (SIG-A) field, a signal-B (SIG-B) field and a short training field (STF), and a long training field (LTF) that provides training symbols; and
blind decoding the SIG-B field using a group identifier (ID) assigned to the STA,wherein the SIG-B field includes information on a number of streams assigned to each of multiple STAs that receive the MU frame, andwherein a starting position of a training symbol interval for the STA in the LTF is implicitly indicated by a number of streams assigned to each of the other STAs in a same group sharing the group ID with the STA, and an order of streams assigned to the STA in the same group.

Abstract
A method for receiving a signal by a station (STA) in a wireless LAN system according to an embodiment of the present invention comprises the steps of: receiving a multi-user (MU) frame including a SIG-A field, a SIG-B field and a short training field (STF), and a long training field (LTF) that provides training symbols; and performing blind-decoding of the SIG-B field using a group ID assigned to the STA, wherein the SIG-B field includes information on the number of streams assigned to each of multiple stations that receive the MU frame, and the starting position of a training symbol interval for the STA in the LTF is implicitly indicated by the number of streams assigned to each of other stations in the same group, which share the group ID with the STA, and the order in which the streams are assigned to the STA in the same group.

10. A station (STA) in a wireless local area network (LAN) system, the STA comprising:
-
a receiver to receive a multi-user (MU) frame including a signal-A (SIG-A) field, a signal-B (SIG-B) field and a short training field (STF), and a long training field (LTF) that provides training symbols; and a processor to blind decode the SIG-B field using a group identifier (ID) assigned to the STA, wherein the SIG-B field includes information on a number of streams assigned to each of multiple STAs that receive the MU frame, and wherein a starting position of a training symbol interval for the STA in the LTF is implicitly indicated by a number of streams assigned to each of the other stations in a same group sharing the group ID with the STA, and an order of streams assigned to the STA in the same group. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
