Method and apparatus to determine location for an unmanned aerial vehicle (uav)

A method to determine location for an unmanned aerial vehicle (UAV) serving a plurality of terrestrial user equipment (UEs), the method comprising:

• determining that the plurality of terrestrial UEs are uniformly distributed in a cell;
• receiving location coordinates of the plurality of terrestrial UEs;
• determining a plurality of location parameters of the UAV using the location coordinates of the plurality of terrestrial UEs, wherein the plurality of location parameters includes at least one of a 2-D ground distance of the UAV, a 2-D polar angle the UAV makes relative to a positive x-axis passing through a center of the cell, and a height of the UAV;
• and
• transmitting the plurality of location parameters to the UAV.

An apparatus to determine location for an unmanned aerial vehicle (UAV) serving a plurality of terrestrial user equipment (UEs), the apparatus comprising:

• a transceiver;
• and
• a processor configured to:
• receive, via the transceiver, information from a network entity, the information indicating that the plurality of terrestrial UEs form a cluster;
• determine whether at least one of a plurality of predefined events is triggered;
• and
• determine the location of the UAV, in case that the plurality of terrestrial UEs form the cluster and the at least one of the plurality of predefined events is triggered, wherein determining the location comprises:
• receiving cluster information related to the cluster;
• determining circular trajectory of the cluster using the cluster information;
• receiving a first average data rate of the cluster at a plurality of locations along the circular trajectory;
• determining an optimal down-tilt angle and an optimal bearing angle of an antenna panel of the UAV at the plurality of locations;
• and
• determining the location of the UAV based on the optimal down-tilt angle and the optimal bearing angle.
