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.
