METHOD AND APPARATUS FOR TRANSMITTING ADAPTIVE PARTIAL SUBFRAME IN UNLICENSED FREQUENCY BAND, METHOD AND APPARATUS FOR IDENTIFYING A FRAME STRUCTURE, AND METHOD AND APPARATUS FOR TRANSMITTING SIGNAL

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.
