US 9,872,181 B2 · Method for transmitting data on unlicensed band and base station therefor

Abstract

One disclosure of the present specification provides a method by which a long term evolution advanced (LTE-A)-based base station transmits data on an unlicensed band. The method can comprise the steps of: setting, by the base station, a listen before talk (LBT) configuration for determining whether to transmit signals of other nodes before transmitting data on the unlicensed band; measuring, by the base station, interference due to signals from other nodes during a preset measurement period; comparing the detected interference and a preset threshold value; changing the LBT configuration according to the comparison; and transmitting the changed LBT configuration to a terminal.

A method of transmitting data in an unlicensed band, the method performed by a Long Term Evolution Advanced (LTE-A)-based base station and comprising:

before transmitting the data in the unlicensed band, setting, by the base station, Listen Before Talk (LBT) configuration to determine whether other nodes transmit signals or not;
measuring, by the base station, interference caused by the signals from the other nodes for a preset measurement period;
comparing the measured interference with a preset threshold;
changing the LBT configuration according to the comparison;
and
transmitting the changed LBT configuration to a terminal.

3 more elements

A Long Term Evolution Advanced (LTE-A)-based base station which transmits data in an unlicensed band, the base station comprises:

a Radio Frequency (RF) transceiver;
and
a processor configured to control the RF transceiver,
wherein the processor performs the following operations:
before transmitting the data in the unlicensed band, setting Listen Before Talk (LBT) configuration required to determine whether to transmit signals of other nodes;
measuring, by the base station, interference caused by the signals from the other node for a preset measurement period;
comparing the measured interference with a preset threshold;
changing the LBT configuration according to the comparison;
and
transmitting the changed LBT configuration to a terminal.
