Abstract: Provided are a method and apparatus for performing beamforming training in a wireless local area network. A responder receives a plurality of beacon frames in a plurality of TX sectors from an initiator during a transmission (TX) beamforming (BF) interval. The responder transmits a first sector sweep feedback for a first array antenna to the initiator during a reception (RX) beamforming (BF) interval. The first sector sweep feedback comprises a first antenna ID indicating a first array antenna and a first TX ID indicating a TX sector selected for the first array antenna from the plurality of TX sectors.

Abstract: Provided is a method and an apparatus of configuring a LTF sequence in a wireless LAN system. In specific, a transmitting apparatus configures a LTF sequence of a second wireless LAN system by using a LTF sequence of a first wireless LAN system. The transmitting apparatus transmits the LTF sequence of the second wireless LAN system via a PPDU including a first field region and a second field region. The LTF sequence of the second wireless LAN system includes a first LTF sequence obtained by up-scaling a frequency index of the LTF sequence of the first wireless LAN system by four times and a second LTF sequence obtained by adding a frequency index which an optimized coefficient is applied. A phase rotation is applied to the LTF sequence of first wireless LAN system as per a first frequency band.

Abstract: The present document relates to a wireless communication system and, more particularly, to a method for performing communication using a downlink (DL) oriented channel in a high-density wireless LAN system and an apparatus therefor. A particular station STA1 configured therefor connects with an AP through a normal channel, switches to a downlink oriented channel during an active mode operation, and receives data from the AP through the DL oriented channel. Meanwhile, data is transmitted to the AP through switching to the normal channel. Here, the first station obtains information on a specific interval for receiving data from the AP through the downlink oriented channel, switches to the normal channel during an interval other than the specific interval, and transmits data to the AP.

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.
