Abstract: A method for frame retransmission performed by a first wireless terminal in a wireless LAN system comprises the steps of: dividing an MSDU received from an upper layer of a first wireless terminal into multiple MPDUs; transmitting the multiple divided MPDUs to a second wireless terminal, wherein each of the multiple divided MPDUs includes division information and transmission sequence information; if an ACK frame for notifying of successful reception of the multiple divided MPDUs is not received until a preset time elapses, transmitting, to the second wireless terminal, a BAR frame for determining at least one MPDU to be retransmitted by the first wireless terminal among the multiple divided MPDUs; receiving a BA frame from the second wireless terminal in response to the BAR frame, wherein the BA frame includes frame information indicating a last MPDU successfully received by the second wireless terminal among the multiple divided MPDUs; and performing a retransmission procedure on the basis of the frame information.

Abstract: A method for transmitting a frame in a wireless LAN system, according to one embodiment of the present specification, comprises the steps of: a wireless terminal determining whether a channel is usable based on directional CCA which confirms the state of individual channels; determining, as a primary AC, the first AC type from a plurality of AC types to complete a first back-off process, when either a first channel or a second channel is determined as usable; and determining a primary AC from the plurality of AC types once again by performing a second back-off process, when transmission of traffic data included in a transmission que corresponding to the primary AC using at least one directional antenna module associated with at least one channel is determined to be impossible.

Abstract: The present specification relates to a method for transmitting and receiving signals by a station in a wireless LAN (WLAN) system. More specifically, the present specification proposes a method for providing information on a primary channel and information on a channel for transmitting signals when a station transmits signals by bonding or combining a plurality of channels, and suggests a method for transmitting and receiving signals on the basis of such method for providing information, and an apparatus therefor.
