Abstract:
Disclosed are operation method of station in wireless local area network. An operation method comprises setting transmission power of a frame; setting a clear channel assessment (CCA) threshold based on a difference between the set transmission power and a default value of the transmission power; and performing a CCA operation based on the set CCA threshold. Therefore, performance of WLAN can be enhanced.
Abstract:
A method of transmitting a frame is provided by a device in a WLAN. The device sets as additional data subcarriers some of subcarriers which are not set as data subcarriers in at least part of fields included in a frame of a legacy frame format, and allocates information to the additional data subcarriers.

Abstract:
An ACK method is provided by a receiving device in a WLAN. The receiving device receives a plurality of data units having a plurality of TIDs and transmits an ACK frame including a plurality of ACK information fields for at least part of the plurality of data units. An ACK information field for a data unit satisfying a first condition among the plurality of ACK information fields includes a TID and a block ACK bitmap indicating whether the data unit has been successfully received. An ACK information field for a data unit satisfying a second condition and having been successfully received among the plurality of ACK information fields includes the first TID and does not include a block ACK bitmap.

Abstract:
Disclosed are a method and an apparatus for transmitting and receiving data in a Wireless Local Area Network (WLAN) system. A method for transmitting data may comprise generating a physical layer (PHY) frame including a payload in which a plurality of Medium Access Control protocol data units (MPDUs) are multiplexed; and transmitting the PHY frame, wherein the PHY frame includes information on subcarriers occupied by each of the plurality of MPDUs in an Orthogonal Frequency Division Multiplexing (OFDM) symbol of the payload. Therefore, data transmission efficiency in a WLAN system can be enhanced.
