Abstract: Disclosed are operation methods of station based on station density in wireless local area network. An operation method comprises obtaining density-related information indicating a station density state within a communication area of the first station; and transmitting a notification frame including at least one of an operation mode indication information and a clear channel assessment (CCA) threshold that are set based on the density-related information. Therefore, performance of WLAN can be enhanced.

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.

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 translation: WLAN中的接收设备提供ACK方法。 接收装置接收具有多个TID的多个数据单元，并发送包含多个数据单元的至少一部分的多个ACK信息字段的ACK帧。 在多个ACK信息字段中满足第一条件的数据单元的ACK信息字段包括指示数据单元是否已被成功接收的TID和块ACK位图。 在多个ACK信息字段中满足第二条件并已成功接收的数据单元的ACK信息字段包括第一TID，并且不包括块ACK位图。
