Abstract
An energy efficiency optimization method for an IRS-assisted NOMA THz network comprises: classifying users into BS users and IRS users; defining a channel model for the BS users and a channel model for the IRS users; calculating a BS user rate and an IRS user rate respectively, and calculating a total rate of a system; proposing an optimization problem for downlink power control and IRS phase shift adjustment; and solving the optimization problem through an MADRL method. The invention puts forward an energy efficiency concept and adopts an MADRL method to maximize the overall energy efficiency of the system under the constraints of minimum rate and maximum power of each user.
