Abstract: According to one embodiment of the present invention, an AP generates a frame including a signaling field and a data field so as to transmit the frame to one or more STAs, wherein: the signaling field includes a first signaling field having first common control information on the one or more STAs, and a second signaling field having individual control information for each of the one or more STAs; and the second signaling field includes a common field having second common control information on the one or more STAs, and individual fields having individual control information for each of the one or more STAs. In addition, if the frame is transmitted with a bandwidth of 40 MHz or more, the second signaling field transmits independent control information in two adjacent 20 MHz bands.

Abstract: A method and apparatus for transmitting frames having a long training field (LTF) for a second type of station (STA) in a wireless communication system are provided. For this, STA prepares a frame having a first part for a first type of STA and a second part for the second type of STA; wherein the second part includes multiple LTFs, when the frame is used for MU (Multiple User) transmission scheme or OFDMA (Orthogonal Frequency Divisional Multiple Access) scheme. In case a first LTF having a first number of symbols length and a second LTF having a second number of symbols length, which is greater than the first number of symbols length, are used for the multiple LTFs, the first LTF is extended such that the first LTF and the second LTF have a same number of symbols length. The STA transmits the prepared frame to one or more STAs.

Abstract: A method for receiving a signal by a station in a wireless LAN system, according to an embodiment of the present invention, comprises the steps of: receiving one of a plurality of per channel SIG-Bs, comprised in a SIG-B field, via a first channel among the transmission bandwidth of a multi-user (MU) frame comprising SIG-B field and data; and receiving the data of the MU frame on a second channel differing from the first channel via which the per channel SIG-Bs have been received. Although any one of the plurality of per channel SIG-Bs is transmitted on the second channel, the data of the MU frame is received by means of the per channel SIG-Bs that are transmitted on the first channel instead of the per channel SIG-Bs that are transmitted on the second channel.

Abstract: Disclosed is a method for reducing power consumption by a station (STA) in a mobile communication system. When a trigger frame including a common information field and a user information field is received from an access point (AP), the user information field indicates different information in the case where an association ID (AID) subfield of the user information field has a first value indicating resource allocation for random access and in the case where the AID subfield of the user information field has a value other than the first value. In addition, when the AID subfield has the first value, the user information field includes information indicating whether a resource for random access is allocated, and the STA may transition to a doze state on the basis of the information indicating whether a resource for random access is allocated.

Abstract: Provided is an example related to a control field which is used for PPDU in a wireless LAN system supporting a plurality of RUs. An additional identifier can be comprised in the control field for PPDU. An identifier value comprised in the control field is preferably determined on the basis of whether or not only one RU corresponding to the full bandwidth of a transmission frequency band is arranged. Comprising of information for allocation of RU of the PPDU can be determined on the basis of the identifier value comprised in the control field.
