The present disclosure relates to a 5G or pre-5G communication system to be provided in order to support higher data rates after a 4G communication system, such as an LTE system. A method for receiving buffer status information by an access point in a wireless communication system is provided. In the method, a contention sub-slot and a dedicated sub-slot are determined for each station connected to the access point, a data trigger action frame is generated based on a first element including allocation information on the dedicated sub-slot to be used by a related station in a buffer status report (BSR) phase where each of the stations transmits buffer status information to the access point, the generated data trigger action frame is broadcasted to the stations, and a BSR frame transmitted based on the data trigger action frame is received from each of the stations.
