Embodiment Construction

[0053] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0054] refer to figure 1 , a method for maximizing the throughput of energy-intensive wireless relay networks based on deep deterministic policy gradients, in other words, maximizing system benefits by maximizing throughput end-to-end through joint time scheduling and power allocation. The present invention is based on an energy-collecting wireless relay network system (such as figure 1 shown). In the energy-intensive wireless relay network system, the time scheduling and power allocation are optimized through the deep deterministic policy gradient method to achieve the maximum transmission rate. The invention proposes a renewable energy optimization method for maximizing throughput for the time scheduling and power control problems in energy-collecting wireless relay networks under the condition of limited data cache and energy storage batteries. The metho...

Abstract

A method for maximizing throughput of a centralized radio relay network based on depth deterministic policy gradient comprises the following steps: 1) maximizing throughput in the centralized radio relay network through regenerative energy optimization management, wherein, the optimization problem is described as a multivariable optimization problem; 2) decomposing the problem P1 into two parts ofoptimization: Power sub-optimization and slot sub-optimization, i.e., deep deterministic strategy gradient method optimizes variables pi and (img file = 'DDA000173585526000011. TIF' wi= '48' he= '66' / ) to obtain the optimal ri. A method for maximizing system efficiency with maximum throughput in a centralized radio relay network by combining time scheduling and power allocation is provided.

Description

technical field [0001] The invention relates to the technical field of energy-collecting wireless relay networks, in particular to a method for maximizing the throughput of energy-collecting wireless relay networks based on deep deterministic policy gradients. Background technique [0002] Mobile data traffic has been growing exponentially due to the proliferation of wireless devices and emerging multimedia services. Due to channel losses such as path loss, shadowing, and small-scale fading, more and more indoor and edge users may experience low-quality service performance. To overcome this obstacle, relay-assisted access technology has been proposed as a valuable solution to exploit energy efficiency and spatial diversity to improve user service quality indoors and at the cell edge. The relay base station will serve as a relay station for communication between edge users and macro cell base stations. [0003] However, the energy consumption generated by densely deploying ...
