摘要： 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.

摘要： The present disclosure is related to a 5th Generation (5G) or pre-5G communication system for supporting a higher data rate than a 4th Generation (4G) communication system such as Long Term Evolution (LTE). A method for operating a terminal in a wireless communication system is provided which includes receiving downlink data from a base station; performing listen-before-talk (LBT) for uplink transmission; transmitting a first reservation signal based on an end timing of the LBT and a subframe boundary; and transmitting uplink data to the base station based on the subframe boundary.

摘要： 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.

摘要： A communication method using a plurality of channels in a wireless communication system supporting an unlicensed band. The communication method includes: performing listen-before-talk (LBT) for transmitting a random access preamble on each of a plurality of control channels supported by a user equipment (UE), from among a plurality of control channels supported by a base station; transmitting a random access preamble through a control channel where the LBT succeeded from among the plurality of control channels where the LBT for transmitting the random access preamble is performed; and receiving a random access response (RAR) through a control channel determined according to a result of the LBT performed by the base station, from among the plurality of control channels supported by the UE, wherein a control channel is a channel through which a control signal and a data signal are transmitted and received.

摘要： This specification provides a method for performing a discovery procedure in a wireless communication system supporting device to device (D2D) communication. The method is performed by first user equipment and includes monitoring a discovery resource region, selecting a discovery resource for transmitting a discovery message in the discovery resource region, and transmitting the discovery message to second user equipment through the selected discovery resource. The selected discovery resource includes a discovery resource having a received energy level corresponding to a threshold value or less or a threshold value or higher.
