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.

Abstract: A method and apparatus for transmitting and receiving a frame including a partial association ID (PAID) in a wireless LAN (WLAN) system are disclosed. A method for transmitting a frame from a station (STA) to an access point (AP) in a wireless communication system includes: calculating a partial association ID (Partial AID) on the basis of a basic service set ID (BSSID) of the AP; and transmitting the frame including a partial AID field set to a specific value corresponding to the calculation result of the partial AID to the AP. The partial AID is calculated by applying a modulo operation to a specific value obtained by converting values ranging from a 40th bit position to a 48th bit position from among 48 bit positions of the BSSID of the AP into a decimal number.
