Abstract: A method for performing network allocation vector (NAV) operation by a station (STA) in a wireless LAN system, according to an embodiment of the present invention, comprises the steps of: receiving a first frame; and configuring NAV in accordance with basic service set (BSS) of the first frame, wherein the first frame is other BSS (OBSS) frame. If a received signal strength indicator (RSSI) is lower the OBSS packet detection (PD) level, an STA drops the OBSS frame without configuration of the NAV. And if second frame transmission of another STA following the OBSS frame is scheduled, the STA can defer the OBSS frame drop even if the RSSI is lower than the OBSS PD level.

Abstract: A wireless communication system is disclosed. Disclosed herein are methods for transmitting a physical uplink control channel (PUCCH) signal in a wireless communication system, which includes setting transmit power for the PUCCH signal, and an apparatus thereof. If the PUCCH signal is transmitted on a subframe configured for a scheduling request (SR), the PUCCH signal includes one or more hybrid automatic repeat request acknowledgement (HARQ-ACK) bits and an SR bit. When determining the transmit power for the PUCCH, the SR bit is selectively considered depending on whether or not a transport block for an uplink shared channel (UL-SCH) is present in the subframe.
