摘要： A method of controlling uplink access in a wireless communication system is provided. The method includes: generating an access probability sequence consisting of an access probability determined with respect to a radio resource used for data transmission; transmitting data according to the access probability included in the access probability sequence; receiving a success / failure result on the data transmission; and regulating the access probability used in the data transmission according to the success / failure result. Accordingly, each user equipment performs a simple control process for attempting random uplink access according to an access probability sequence and for changing the access probability sequence according to success / failure of uplink data transmission, thereby decreasing a probability of collision between user equipments, thereby increasing data transmission efficiency in a system employing a plurality of user equipments.

摘要： The present invention relates to a method and device for channel measurement in a wireless LAN system. A station (STA) receives a plurality of sounding frames from an access point (AP), estimates the plurality of sounding frames in order to generate long-term channel state information (LCSI), provides the generated LCSI to the AP as feedback, and receives from the AP a group identifier (ID) management frame comprising information on a group ID determined on the basis of the LCSI.
