Title:
METHOD AND APPARATUS FOR OPTIMIZING TILT ANGLE OF ANTENNA OF BASE STATION
Document Type and Number:
WIPO Patent Application WO/2022/124860
Kind Code:
A1
Abstract:
The present disclosure relates to a method for optimizing the tilt angles of antennas installed in a plurality of base stations within a network including the plurality of base stations, the method being carried out by a processor of a central server that controls operations of a plurality of base stations, and comprising the steps of: collecting density information of base stations and terminals within a network, height information of the base stations and terminals, and network environment parameter information; in a first environment in which all of a plurality of base stations communicate with both airborne terminals and ground terminals, calculating, on the basis of the density information and the height information, a first network outage probability that is a network outage probability for the first environment; in a second environment in which a first group of base stations from among the plurality of base stations communicate with airborne terminals, and a second group of base stations from among the plurality of base stations communicate with ground terminals, calculating, on the basis of the density information and the height information, a second network outage probability that is a network outage probability for the second environment; comparing the first network outage probability with the second network outage probability; and adjusting the tilt angles of the antennas of all of the plurality of base stations to a first optimal angle when the first network outage probability is less than the second network outage probability, and, when the first network outage probability is greater than or equal to the second network outage probability, adjusting the tilt angles of the antennas of the first group of base stations to a 2-1st optimal angle and adjusting the tilt angles of the antennas of the second group of base stations to a 2-2nd optimal angle.
