Problems solved by technology

Also note that compared to OMA, NOMA is more complex to implement and requires multiuser detection (MUD) techniques at the receiver, such as sequential interference cancellation (SIC), to decode the received signal at the cost of increased computational complexity

Abstract

The invention discloses an unmanned aerial vehicle auxiliary communication resource allocation method of a Hybrid NOMA network. Acording to the multi-cell multi-channel mixed NOMA / OMA small cellular network based on user experience, a joint resource allocation problem is decomposed into two sub-problems of three-party matching and similar water injection type MOS power allocation, and the method comprises the following steps: 1, modeling a multi-carrier NOMA network system scene; 2, decomposing and mathematically describing a wireless resource allocation problem of non-orthogonal multiple access of multiple cells and multiple carriers; 3, designing a multi-objective optimization adaptation method for base station selection, sub-channel matching, unmanned aerial vehicle height optimizationand power distribution. According to the invention, after establishing a hybrid NOMA-oriented multi-cellular unmanned aerial vehicle auxiliary communication system, a user experience QoE-based unmanned aerial vehicle / base station-user-sub-channel three-dimensional matching strategy and an unmanned aerial vehicle height optimization and power distribution mode conforming to the scene are innovatively provided; by taking maximization of user experience as a final target, the problem of unreasonable resource allocation caused by blindly pursuing the maximum rate is avoided, and the wireless resource allocation efficiency based on the NOMA scene is improved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a wireless resource allocation method of NOMA and OMA hybrid heterogeneous small cell networks based on user experience, in particular to an unmanned aerial vehicle-assisted communication resource allocation method of the hybrid Hybrid NOMA network. Background technique [0002] As we all know, the future wireless network needs to meet the communication connection anytime and anywhere with diversified communication modes. To improve the resilience of communication networks to emergencies such as failures, natural disasters, and unexpected traffic, unmanned aerial vehicle (UAV)-assisted wireless communication systems can provide a unique opportunity to meet these needs in a timely manner without relying on over-engineering cellular network. Drones can serve as unmanned aerial vehicle base stations (UAV-bs) to handle short-term erratic traffic demands in hotspots such...
