Abstract

The invention belongs to the technical field of wireless communication resource allocation, and specifically relates to a power allocation method based on energy efficiency required by a user side. The present invention relates to theoretical frameworks such as energy efficiency (Energy Efficiency), power control (Power Control), and user satisfaction (User Satisfaction Degree). Based on energy efficiency, the present invention constructs a new type of user satisfaction function in a multi-user OFDM downlink scenario, proposes a system optimization objective function that comprehensively considers system-side requirements (EE) and user-side requirements (USD), and uses a damped Newton architecture (Damped Newton Method) and Lagrange multiplier method to solve the power allocation problem under this linear constraint. Compared with the traditional power allocation method, the present invention achieves a better balance between system performance requirements and user performance requirements, and is more flexible in power allocation.

Description

technical field [0001] The invention belongs to the technical field of wireless communication resource allocation, and specifically relates to a power allocation method based on energy efficiency required by a user side. The present invention relates to theoretical frameworks such as energy efficiency (Energy Efficiency), power control (Power Control), and user satisfaction (User Satisfaction Degree). Background technique [0002] Signal transmission schemes based on energy efficiency (EE) have become one of the mainstream research directions to address the challenges of increased energy consumption and green communication requirements in next-generation mobile communications. Compared with the traditional transmission power allocation schemes such as maximizing system throughput or minimizing system energy consumption, the power allocation scheme based on energy efficiency improves the system energy utilization under the condition of comprehensive consideration of channel q...
