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: A communication node configures an unlicensed band transmission burst including a plurality of subframes in consideration of an occupancy state of a channel of an unlicensed band and transmits the unlicensed band transmission burst through the unlicensed band. In this case, at least one subframe of the plurality of subframes has a different type from the remaining subframes.

Abstract: A method for transmitting an uplink signal in an unlicensed band by a terminal is provided. The terminal receives first scheduling information that schedules one or more uplink subframes, from a base station in a first downlink subframe. The terminal receives second scheduling information that determines a transmission time point of the uplink signal, from the base station in a second downlink subframe after the first downlink subframe. The terminal transmits the uplink signal in a first uplink subframe corresponding to the transmission time point among the one or more uplink subframes.

CPC classification number: H04W74/085 , H04W84/12
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.
