Abstract: Proposed are a method and a device for transmitting a signal including a data field in a wireless LAN. For example, an access point (AP) allocates, to a second station, a second frequency band adjacent to a first frequency band, wherein the second frequency band can include a plurality of resource units. In addition, a signal including the data field can be transmitted to the second station through the allocated second frequency band. Furthermore, when the first frequency band is allocated to the first station, the AP can allocate, to the second station, as a null resource unit, a resource unit adjacent to the first frequency band among the plurality of resource units.

Abstract: Disclosed are a method and a device for recovering an error without the retransmission of a data frame in a wireless LAN. The method for recovering an error in a wireless LAN may comprise the steps in which: a sender STA transmits a data frame to a receiver STA; if the sender STA does not receive a block ACK frame of the data frame from the receiver STA, the sender STA determines the reason for the non-reception of the data frame; if the sender STA determines that the reason for the non-reception of the data frame is the failure of transmission of the block ACK frame after the receiver STA receives the data frame, the sender STA transmits a PBAR data frame to the receiver STA; and the sender STA receives a PBAR block ACK frame from the receiver STA as a response to the PBAR data frame.
