Abstract: Disclosed is a method for allocating a resource of a terminal. The method includes: receiving downlink data from a base station; and allocating a resource for a device-to-device communication to a sub-frame by considering a hybrid ARQ (HARQ) transmission delay with respect to the received downlink data.

Abstract: Disclosed is a communication method for coexisting with a non-licensed band communication system of a non-licensed band in a licensed band communication system. The method includes: transmitting a signal by a transmitter in order to operate in a non-licensed band, when the signal is a transmission target signal having frames and a wireless local area network (WLAN) preamble signal is inserted to the front of each frame of the transmission target signal; and extracting the WLAN preamble signal from the signal of the transmitter by a receiver to synchronize with the transmitter.

Abstract: Disclosed herein is a method for transmitting, by a terminal, a sounding reference signal (SRS). The terminal receives a grant for uplink multiple subframes from a base station. The terminal determines a first subframe for an SRS transmission of the terminal among the uplink multiple subframes on the basis of SRS transmission position information received from the base station. Further, the terminal transmits the SRS in the first subframe.

Abstract: Disclosed is a method for communicating in a network supporting licensed and unlicensed bands. A terminal operation method comprises the steps of: detecting a control channel of a subframe #n transmitted from a base station; obtaining, from the control channel, a DCI for an uplink grant; executing channel sensing on the basis of channel connection-related information included in the DCI; and transmitting, to the base station, a subframe #(n+1) if the result of executing channel sensing is an idle state. Thus, the performance of the communication network may be improved.

Abstract: Disclosed is a method for scheduling an uplink transmission in a communication network. A terminal operation method comprises the steps of: detecting a control channel of a subframe #n transmitted from a base station; receiving an uplink grant from the control channel; and transmitting, to the base station, a plurality of subframes scheduled by the uplink grant. Thus, the performance of the communication network may be improved.

Abstract: A wireless device of a communication system randomly selects a backoff counter at a contention window interval corresponding to a contention window size that is determined according to a backoff stage, attempts packet transmission, when the backoff counter becomes 0 while reducing the backoff counter, when a radio channel is in an idle status, and increases the contention window size while increasing the backoff stage by 1 according to a first predetermined condition. In this case, as the backoff stage increases, a contention window size has a concave down increasing form.
