Embodiment Construction

[0060] The specific implementation method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0061] In order to improve the system capacity between UAV groups, the present invention constructs a two-layer UAV communication architecture with a millimeter wave base station and K small UAV machine groups, and models UAV communication in the millimeter wave frequency band. Consider the path loss of UAV mmWave communication under line-of-sight and non-line-of-sight and modeling of UAV movement trajectory. Analyze the influence of drone cluster density, cluster moving speed, and aircraft receiving antenna direction angle on channel quality. The base station UAV follows the proposed heuristic dichotomous iteration method in the millimeter wave frequency band to jointly allocate the beam and power of the fifth generation communication (5G) inter-UAV communication, which reduces the interference between UAV beams and improves pow...

Abstract

The invention provides an allocation algorithm of joint beam and power for 5G unmanned aerial vehicle communication, and belongs to the field of communication. The method comprises the following steps: firstly, constructing unmanned aerial vehicle communication architecture, sending, by a millimeter wave base station, a communication signal, calculating an SINR of each miniature unmanned aerial vehicle in an unmanned aerial vehicle group based on adaptive beam forming, and separately calculating the respective allocated link capacity; then, in combination with the link capacity of each miniature unmanned aerial vehicle, constructing constraint conditions and an objective function to maximize the system capacity of the communication architecture; and finally solving the objective function,and performing beam and beam power resource allocation on the miniature unmanned aerial vehicle group within a millimeter wave band. By adoption of the allocation algorithm provided by the invention,the number of iterations is reduced, the fast beam and power joint allocation is achieved, the fairness of the unmanned aerial vehicles is ensured, and the system capacity is also improved.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a joint beam and power allocation algorithm for 5G unmanned aerial vehicle communication. Background technique [0002] As a mobile communication device, drones have the advantages of small size, large visual communication area, and strong mobility. Rebroadcast) communication requirements, so it is widely used in the fifth-generation mobile communication 5G scenario. [0003] At present, the research on UAVs is mainly focused on flight control and image stabilization acquisition. For the research on UAV communication, there are related documents that define the communication frequency band of UAV: ​​WIFI communication standard based on 802.11 and LTE communication frequency band ; As a result, the research scenarios are mainly limited to WIFI frequency band and LTE frequency band communication. The research on UAV networking and high frequency band communication is relat...
