Abstract: When an AP (access point) performs sounding to transmit a frame to one or more STAs using a beamforming scheme in a wireless LAN (WLAN) system, the AP receives a beamforming feedback, which is generated based on measurement of a specific signal transmitted by the AP in a manner that the one or more STAs group a prescribed number of tones according to a tone grouping element (Ng). In this case, the Ng is configured by a multiple of 4.

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.
