Abstract

The invention discloses an energy-efficiency-based power control method for a full-duplex non-orthogonal multiple access system, and belongs to the field of network power control. According to the method, an optimization model is established for an energy efficiency problem of a single-carrier non-orthogonal multiple access system which provides services for a plurality of half-duplex downlink users and uplink users at the same time by adopting a full-duplex base station, and then the transmission power is distributed by adopting a fractional programming and an iterative algorithm based on a lagrangian multiplier, so that the system energy efficiency is maximized. According to the method, the energy efficiency of the full-duplex NOMA system is improved, and the calculation complexity is reduced to a certain extent.

Description

technical field [0001] The invention belongs to the field of non-orthogonal multiple access communication, in particular to an energy efficiency-based power control method with service quality guarantee in full-duplex non-orthogonal multiple access. Background technique [0002] In the latest 5G new multiple access technology research, non-orthogonal multiple access technology based on power domain multiplexing is a promising technology for improving system capacity, frequency efficiency, and energy efficiency in 5G networks. Compared with the traditional OMA technology, the NOMA technology has the following advantages: higher spectral efficiency, higher cell edge throughput, lower transmission waiting time, enhanced user fairness, and support for more user connections. [0003] However, most of NOMA's work to date has been limited to half-duplex operation. Both NOMA and full-duplex technology improve spectrum efficiency. A potential application of full-duplex transceivers...
