Abstract

The invention belongs to the technical field of mobile communication, and particularly relates to a QoE (Quality of Experience)-based MIMO (Multiple Input Multiple Output) NOMA (Non-Orthogonal Multiple Output) system power distribution method, which comprises the following steps of: establishing a webpage browsing service MOS (Metal Oxide Semiconductor) model under an MIMO NOMA system, and obtaining a mapping relationship from a user rate to an MOS function; based on the Stackelberg game thought, a base station serves as an owner of power resources and is set as a seller in the game, and a user serves as a competitor of the resources and is set as a buyer in the game; establishing a maximum MOS utility function of the user side by taking the maximum MOS value as an optimization target; setting unit power cost, and establishing a maximum utility function of the base station end; solving an optimal power expression and an optimal unit power price allocated by the user by using a KKT condition; updating the Lagrange multiplier for iteration until the user and the base station reach Stackelberg equilibrium; and calculating the MOS value of the user according to the finally converged power value, and completing power distribution. According to the invention, the performance of the 5G communication system can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a QoE-based MIMO-NOMA system power allocation method. Background technique [0002] With the vigorous development of mobile communication, the number of users accessing in wireless communication systems is increasing explosively. However, due to limited spectrum resources, traditional orthogonal multiple access multiplexing technology can no longer meet the increasing demand of system access capacity. Therefore, the Non-Orthogonal Multiple Access (NOMA) technology was born, which can realize multiplexing of multiple users on the same time-frequency resource block, and improve the utilization rate of a unit spectrum. [0003] At the same time, Multiple-Input Multiple-Output (MIMO) technology uses multiple antennas at the transmitting end and receiving end, which can greatly increase the number of system access users, so combining MIMO technology with NOMA ...
