Abstract
Provided is a communication method for interference avoidance in an unlicensed band. A transmission node transmits in the unlicensed band a preemption signal to a target reception node. Upon receiving a ready signal from the target reception node, the transmission node transmits in the unlicensed band a data signal to the target reception node. The preemption signal is transmitted by means of a narrow beam having substantially the same width and direction as the data signal.
Claims10
A method for communicating in an unlicensed band, the method comprising:
- transmitting, by a transmission (TX) node, a preemption signal to a target reception (RX) node in the unlicensed band;
- and
- if the TX node receives a ready signal from the target RX node, transmitting, by the TX node, a data signal to the target RX node in the unlicensed band,
- wherein the preemption signal is transmitted by using a narrow beam having substantially the same width and direction as the data signal.
A device for operating in an unlicensed band, the device comprising:
- a transceiver configured to transmit and receive a radio signal;
- and
- a processor operatively coupled to the transceiver and configured to:
- transmit a preemption signal to a target reception (RX) node in the unlicensed band;
- and
- transmit a data signal to the target RX node in the unlicensed band if a ready signal is received from the target RX node,
- wherein the preemption signal is transmitted by using a narrow beam having substantially the same width and direction as the data signal.
