    Abstract: The present disclosure relates to 5th generation (5G) or pre-5G communication systems to support a higher data rate than the long term evolution (LTE) or other 4th generation (4G) communication systems. A method for transmitting data in a communication system is provided. The method includes identifying, by a station (STA) communicating with a first access point (AP), a resource for performing communication with a second AP positioned adjacent to the STA based on information regarding a capability of the STA, performing the communication with the second AP using the resource, and transmitting data obtained by performing the communication with the second AP to the first AP. The information regarding the capability includes one of information regarding multiple antennas available on the STA, information regarding a base-band processing unit including the multiple antennas, or information regarding a modem including the multiple antennas and the base-band processing unit.

    Abstract: The present invention relates to 5G or pre-5G communication system for supporting a higher data transmission rate after 4G communication system such as LTE. The present invention provides a method and a device for executing a hybrid automatic repeat request (HARQ) through a channel in an unlicensed frequency band. More particularly, a method for executing a HARQ through a channel in an unlicensed frequency band in a terminal of a communication system comprises the procedures of: requesting uplink scheduling; if a first uplink (UL) grant with respect to the scheduling request is received, sensing whether or not a channel is clear; transmitting first uplink data on the basis of whether or not the channel is clear; if negative acknowledge (NACK) with respect to the first uplink grant and a second uplink grant are received, sensing whether or not the channel is clear; and transmitting second uplink data and an indicator, which indicates whether or not the second uplink data transmission is a retransmission, on the basis of whether or not the channel is clear, wherein the indicator, which indicates for retransmission, is determined on the basis of a reference signal (RS) detection failure indicator, of a base station, which is transmitted from the base station together with the second uplink grant.
