Abstract

The invention belongs to the technical field of mobile communication and discloses a power allocation method for a massive MIMO system based on mixed energy collection. In a downlink transmission process of a single-cell multi-user massive MIMO system, a base station is taken as a sending end and is powered by a renewable energy source and a power grid. Renewable energy is collected and then is stored in a battery for data transmission. When the electric quantity of the battery is deficient, the base station ensures service through utilization of the energy of the power grid. According to the method, a mixed energy collection model is established based on energy obtaining renewable energy sources, optimum power is allocated to each user by iterating and updating system information according to channel state and energy state time-variant characteristics and coordination influences between users, the system obtains the highest throughput capacity, and moreover, the non-renewable resources are saved to the greatest extent, thereby achieving a green and energy-saving purpose.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a power distribution method based on hybrid energy collection in a Massive MIMO system. Background technique [0002] With the development of energy harvesting technology, network energy is also gradually enriched. It can not only use traditional power grid power supply, but also use environmental energy (wind energy, solar energy, vibration energy, etc.) On the basis of energy saving and emission reduction, self-sufficient energy supply is realized. However, the energy supply of renewable energy is unstable, and the battery capacity is limited, so it cannot store external energy without limit. Once the energy is exhausted and the transmission is interrupted, in the cellular network It will cause coverage holes and seriously affect the quality of service. Therefore, it is difficult for a base station powered only by renewable energy to maintain a stable ...
