Abstract: A base station of a wireless communication system is disclosed. The base station of the wireless communication includes a communication module; and a processor configured to control the communication module. The processor receives a radio resource control (RRC) signal from a base station of the wireless communication system through the communication module and determines a time-frequency resource corresponding to at least one resource-set indicated by the RRC signal. The processor receives a physical control channel from the base station through the communication module, determines a time-frequency resource domain in which physical data channel reception of the terminal is scheduled by the physical control channel, and receives a physical data channel based on a time-frequency resource in which the physical data channel reception of the terminal is scheduled and a time-frequency resource in which the at least one resource-set overlap. The resource-set is a set of time-frequency resources.

Abstract: A method for performing an uplink transmission to a base station by a user equipment through an unlicensed cell in a wireless communication system is provided. The method includes: receiving an uplink grant that schedules the uplink transmission in at least one subframe from the base station; and performing the uplink transmission in the at least one subframe using at least one of a first type channel access or a second type channel access. The uplink transmission is performed using the second type channel access when all of the at least one subframe is included in a predetermined interval determined based on a downlink transmission through the unlicensed cell from the base station.

Abstract: Provided is a wireless communication terminal that wirelessly communicates with a base wireless communication terminal. The wireless communication terminal includes a transceiver, and a processor. The processor is configured to set an integer selected from a range of 0 to a value equal to or smaller than an OFDMA Contention Window (OCW) as a counter for random access, receive a trigger frame for triggering random access using one or more resource units (RUs) allocated for the random access from the base wireless communication terminal using the transceiver, decrement a value of the counter based on the one or more RUs allocated for the random access, randomly select one RU based on the one or more RUs allocated for the random access when the value of the counter is 0 or reaches 0, and attempt transmission to the base wireless communication terminal using the selected RU.
