1. An electronic apparatus for wireless communications, comprising:
processing circuitry, configured to:
divide available pilots into a plurality of subsets orthogonal to each other; and
allocate a pilot within a first subset to an unmanned aerial vehicle (UAV) device, wherein the first subset is different from a second subset allocated to another UAV device located within an adjacent sector of a different cell, and the first subset is different from a third subset allocated to a ground UE located within the same sector as the UAV device,
wherein the processing circuitry is further configured to:
acquire first information indicating a three-dimensional spatial location of the UAV device;
acquire second information indicating an angle of arrival (AOA) of a signal received by a base station of each adjacent cell from each ground UE of the adjacent cell, the angle of arrival comprising a horizontal incident angle and a vertical incident angle;
determine, based on at least a part of the first information and the second information, a difference between an AOA of a signal received by the base station of the adjacent cell from the UAV device and an AOA of a signal received by the base station of the adjacent cell from its ground UE in a case that the ground UE of the adjacent cell uses the same pilot as the UAV device; and
allocate, to the UAV device, a pilot within the first subset which maximizes the difference.
