Abstract: The present document relates to a method for allocating resources for multi-user or multi-station (STA) data transmission in a wireless LAN system, and an apparatus therefor. To this end, an AP generates a frame including a signaling field and a data field, wherein the signaling field includes a first signaling field (SIG A field) comprising common control information for a plurality of STAs and a second signaling field (SIG B field) comprising user specific control information for each of the plurality of STAs, the second signaling field also comprising data transmission resource allocation information for each of the plurality of STAs. The AP transmits the thus generated frame to the plurality of STAs. If the frame is transmitted with a bandwidth of 40 MHz or greater, the second signaling field transmits independent control information in two adjacent 20 MHz bands, and the second signaling field, transmitted through a specific 20 MHz band, comprises data transmission resource allocation information within the specific 20 MHz band.

Abstract: A method for a station (STA) not having an association identifier (AID) allocated thereto transmitting a signal in a wireless LAN system, according to one embodiment of the present invention, comprises the steps of: transmitting a first frame through at least one resource among resources indicated by a trigger frame; and receiving a multi-STA block Ack (M-BA) frame as a reply to the first frame, wherein, if in the M-BA frame a MAC address of the STA that is different from a first information is detected from at least a part of a first field reserved for the first information, an N-bit of a second field preceding the first field is set as a temporary AID of the STA.

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: A method for transmitting a frame in a wireless LAN system according to the present embodiment comprises: a step of determining whether to transmit a first frame to an AP through an EDCA by comparing a time parameter indicating the time used for transmission of a wireless terminal with a predetermined allowable time; a step of summing up, to the time parameter, a first required time for transmission of the first frame; a step of receiving, from the AP, a trigger frame for multi-user uplink transmission; and a step of performing data processing for a second frame transmitted in response to the trigger frame, wherein a second required time for transmission of the second frame is not summed up to the time parameter.

Abstract: The present specification proposes a signal processing method for changing an operating mode for transmitting a PPDU in a wireless LAN system. Specifically, a first station receives, from the second station, indication information which indicates a change in an operating mode indicating a receiving channel bandwidth and a number of spatial streams supported by a second station during a TXOP interval. When the number of spatial streams and the receiving channel bandwidth decrease, the first station configures a PPDU for the second station by using the indication information after transmitting an ACK for the indication information. When the number of spatial streams and the receiving channel bandwidth increase, the first station configures a PPDU for the second station by using the indication information during a subsequent TXOP interval of the TXOP interval.

Abstract: When an AP detects a collision between a neighbor BSS and a BSS color in a wireless LAN system, the AP can inform an STA of the same through information indicating whether the BSS color is disabled, and set and transmit a TXOP_duration field of a transmitted frame to a specific value differentiated from a normal duration value in order to prevent an erroneous NAV setting of the STA.
