摘要： There is provided a method for transmitting, by a transmitter, a signal through an unlicensed band channel. The transmitter transmits an initial signal through the unlicensed band channel to preoccupy the unlicensed band channel when the unlicensed band channel is in an idle status. The transmitter includes a first partial subframe transmitted after the initial signal in a frame burst depending to transmission timing of the initial signal. Further, the transmitter transmits the frame burst through the unlicensed band channel.

摘要： Disclosed herein is a method for transmitting, by a terminal, an uplink signal using a first cell type representing a cell using a licensed band frequency and a second cell type representing a cell using an unlicensed band frequency. The terminal configures at least one first radio bearer (RB) being able to use a radio resource for the first cell type and a radio resource for the second cell type for an uplink transmission. The terminal configures at least one second RB being able to use a radio resource for the first cell type for an uplink transmission. The terminal includes at least one first logical channel corresponding to the at least one first RB in a first logical channel group, and the terminal includes at least one second logical channel corresponding to the at least one second RB in a second logical channel group.

摘要： Provided is a method for transmitting, by a transmitter, a first data having periodicity through a channel of an unlicensed band:
The transmitter adjusts at least one of transmission timing of the first data and clear channel assessment (CCA) timing for the channel to occupy the channel. The transmitter determines whether the channel may be occupied by performing a CCA on the channel at the CCA timing. The transmitter transmits the first data through the channel at the transmission timing of the first data, when it is determined that the channel may be occupied.
