Abstract: Aspects of the subject disclosure may include, for example, a method in which a processing system obtains geolocation information for an unmanned aerial vehicle (UAV) and for a cell of a terrestrial communication network. The system estimates a distance between the UAV and the cell, calculates an expected receive (RX) power for a signal transmitted from the UAV to the cell, and compares the expected RX power with a threshold power to determine whether the cell is a suitable target cell for a communications handover procedure for the UAV. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a method in which a processing system obtains an indication of user equipment demand associated with mobile devices wirelessly communicating with a first access point using a first radio access technology and a second access point using a second radio access technology; the devices include dual connectivity mobile devices. The first access point shares a total amount of radio frequency spectrum with the second access point. The method also includes determining, based on the indication of user equipment demand, a first split between the first access point and the second access point of the total amount of the radio frequency spectrum; and determining, based on the first split, a second split between the first access point and the second access point of an internet protocol (IP) traffic flow. Other embodiments are disclosed.

Abstract: An architecture to reduce or eliminate uplink interference induced by aerial user equipment (UE) when aerial UE is introduced into groups of terrestrial based UE operating in terrestrial fourth generation (4G) long term evolution (LTE), fifth generation (5G) networks. A method can comprise determining a number of terrestrial based user equipment impacted by uplink interference caused by uplink transmissions associated with aerial user equipment, wherein the aerial user equipment and the terrestrial based user equipment are controlled by serving cell equipment; determining an enclosed area that bounds the number of terrestrial based user equipment; and initiating a carrier aggregation process on the aerial user equipment, wherein the carrier aggregation divides the uplink transmissions associated with the aerial user equipment over a group of serving cell equipment included in the enclosed area.

Abstract: An architecture for facilitating smart physical cell identity (PCI) configuration for aerial network equipment that can used in terrestrial 4G and/or 5G LTE wireless networking paradigms. A method can comprise: receiving, from core network equipment, an instruction to travel from a first geographic location to a second geographic location, wherein the second geographic location has been determined, by the core network equipment, as representing a hotspot location; traveling from the first geographic location to the hotspot location; based on crossing a boundary associated with the hotspot location, initiating execution of a user equipment relay process that transitions the aerial user equipment from being user equipment to being aerial network equipment; and transmitting to the core network equipment that the user equipment relay process has been successfully initiated.
