Abstract
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.
Claims22
A transmission method for a transmitter, the method comprising:
- performing clear channel assessment (CCA) for occupying an unlicensed band;
- and
- after the unlicensed band is determined to be idle as a result of the CCA, transmitting first configuration information through a control channel included in a partial subframe being shorter than a full subframe and transmitting data through a data channel included in the partial subframe,
- wherein the first configuration information indicates a number of symbols occupied in a next subframe following the partial subframe.
A reception method performed through an unlicensed band by a receiver, the method comprising:
- receiving a reference signal from a transmitter after the unlicensed band is determined to be idle;
- and
- receiving first configuration information through a control channel included in a partial subframe being shorter than a full subframe and receiving data through a data channel included in the partial subframe,
- wherein the first configuration information indicates a number of symbols occupied in a next subframe following the partial subframe.
