Embodiment Construction

[0050] Various features of the invention will now be described with reference to the drawings, in which like parts are identified with like reference characters.

[0051] Various aspects of the invention will now be described in greater detail in conjunction with a number of exemplary embodiments. To facilitate an understanding of the invention, many aspects of the invention have been described in terms of sequences of actions to be performed by elements of a computer system or other hardware capable of executing programmed instructions. It will be appreciated that in each of the embodiments, various actions can be performed by dedicated circuitry (eg, interconnected analog and / or discrete logic gates, field programmable gate arrays, etc., for performing specialized functions) , by one or more processors programmed with a suitable instruction set, or by a combination of the two. The term "circuitry" "configured to" perform one or more of the described actions is used herein t...

Abstract

A land network node of a land mobile communication network is operated to serve both land and air coverage on the same carrier frequency. Such operations include directing the first receive beam at the airborne radio node. The second receive beam is directed at the user equipment in the land mobile communication network. The signal received in the first receive beam is filtered to create a replica of the signal transmitted by the over-the-air radio node as received by the second receive beam. The replica is subtracted from the signal received through the second receive beam.

Description

Background technique [0001] The present invention relates to connectivity between terrestrial cellular communication systems and mobile cellular communication devices located in aircraft, and more particularly to terrestrial carrier frequency reuse for air-to-ground communications. [0002] The world is becoming increasingly interconnected, and this has led to growing consumer expectations to be online and experience at least moderate data rates whenever and wherever. In response to these expectations, the next generation of mobile technology, so-called IMT-2020 (5G), targets high-speed mobility. Exemplary scenarios studied are high-speed trains and vehicles on highways, but following recent trends, it is expected that terrestrial in-flight broadband service for aircraft will be in this range - or as user equipment Direct communication between a (UE) and a base station, or via an access point (AP) on the aircraft that aggregates traffic for a certain number of UEs and maintai...
