Abstract: The present disclosure relates to a data transmission apparatus and method using a polarized antenna in a wireless AV system, and a data reception apparatus and method. The present specification provides a method for performing polarization alignment for a downlink on the basis of reciprocity, a method for performing polarization alignment for an uplink, and a method for performing polarization alignment independently for each DMG antenna when one data transmission apparatus or one data reception apparatus uses multiple DMG antennas. Optimal MIMO performance can be guaranteed by aligning polarization between multiple antennas of the data transmission apparatus and the data reception apparatus in the wireless AV system, the polarization alignment for a downlink or an uplink may be selectively performed on the basis of reciprocity, and polarization distortion can be reduced through the independent polarization alignment between each DMG antenna.

Abstract: According to one embodiment of the present disclosure, a method by which a station (STA) receives a wake-up radio (WUR) frame in a wireless LAN (WLAN) comprises the steps of: entering a WUR duty cycle mode in which an on-duration for which a WUR receiver of the STA is awake and an off-duration for which the WUR receiver of the STA is sleeping are alternately repeated; and turning on a primary connectivity radio (PCR) when a WUR frame is detected in the on-duration of the WUR duty cycle mode, wherein, when the WUR frame indicates reception of a PCR beacon frame or a delivery traffic indication map (DTIM), the STA can turn on the PCR after delaying a predetermined time from the detection of the WUR frame according to a time point at which the PCR beacon frame or the DTIM is transmitted.

Abstract: Disclosed is a method by which an operating station (STA) transmits a signal in a multiple user (MU) scheme in a wireless LAN (WLAN) system. In the present method, the STA configures a wireless frame, which includes a data field for data transmission and a signaling (SIG) field including control information, wherein the SIG field includes a SIG A field, which includes bandwidth information indicating the whole bandwidth having a bandwidth of 2n times that of 20 MHz, and a SIG B field, which includes user specific information. Here, the bandwidth information of the SIG A field additionally indicates whether the whole bandwidth includes one or more 20 MHz bands (null channel), which are not used in the data transmission.

Abstract: Disclosed is a method for transmitting a preamble in a wireless LAN system, and a station device for performing the same. To this end, a station for transmitting a preamble configures a wireless frame including a first type terminal frame portion, and a second type terminal frame portion. The first type terminal frame portion includes a first type terminal preamble including a first type terminal short training field (STF) and a first type terminal long training field (LTF), and the second type terminal frame portion includes a second type terminal preamble including a second type terminal SFT and a second type terminal LTF. Here, the station configures the second type terminal preamble by allocating sequence components at an interval of an integer number of tones in a frequency domain and transmits the configured wireless frame to another station.
