Abstract: A method and apparatus for a first station (STA) to transmit an acknowledgement (ACK) signal to a second STA in a wireless local area network (WLAN) are disclosed. For this end, the first STA receive a first type frame aggregated with a second type frame from the second STA, wherein the first type frame does not include a quality of service (QoS) control field while the second type frame includes the QoS control field. Then, the first STA transmits an ACK signal for the first type frame to the second STA based on an ACK policy of the QoS control field of the second type frame.

Abstract: A method and apparatus for transmitting frames having a signaling field (SIG) 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. Here, the second part includes a first signaling field (HE-SIG A) for common control information and a second signaling field (HE-SIG B) for signaling information comprising user specific control information. Regarding the second signaling field, independent signaling information for the second signaling field (HE-SIG B) is to be transmitted for each 20 MHz bandwidth within a first 40 MHz bandwidth. And the signaling information of the first 40 MHz bandwidth is duplicated in a second 40 MHz bandwidth, when the frame is to be transmitted in a bandwidth equals to or greater than 80 MHz. STA transmits this prepared frame to one or more STAs.

Abstract: Improved uplink multi-user (UL MU) resource allocation is proposed. For the UL MU scheduling information of trigger frame, N (N>1) bits indicate allocated resource unit (RU) in unit of 26-tone RU, 52-tone RU, 106-tone RU, 242-tone RU, 484-tone RU and 996-tone RU in 80 MHz, and indicates the allocated RU in 80+80 MHz. The UL MU scheduling information of a multi-user request-to-send (MU-RTS) frame indicates an allocated channel corresponding to ‘242*M’-tone RU with a same bit pattern as the N bits of the first UL MU scheduling information, wherein ‘M’ is an integer greater than 0.
