Abstract: A 5th generation (5G) or a pre-5G communication system to support a higher data transmission rate than a system after a 4th generation (4G) communication system such as long-term evolution (LTE) is provided. A method of determining a carrier sense threshold by one source terminal in a wireless communication system is provided. The method includes identifying whether one or more interferer terminals and one or more destination terminals exist for one source terminal, and if the terminals exist, determining a carrier sense threshold of each of the one or more interferer terminals and the one or more destination terminals based on an interference intensity received from the one or more destination terminals and a feedback link margin.

Abstract: 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.
