Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an energy-efficient transmission method and device for rescue data in a heterogeneous network. Background technique [0002] The energy consumed by information and communication technology (Information and Communication Technology, ICT) is increasing at a rate of 15%-20% per year, making it gradually become an increasingly important factor in global greenhouse gas emissions. In order to reduce the impact of the ICT industry on the environment, more and more people are paying attention to how to reduce the energy consumption of related industries. Green Communication (GreenRadio, GR) is oriented to the future mobile communication system, aiming at proposing a network architecture and transmission technology with high energy efficiency, which has attracted extensive attention from industry and academia. In order to meet the growing demand for data services, the futu...

Problems solved by technology

[0004] From the perspective of energy consumption, CoMP-JP can obtain higher array gain by adopting multi-cell joint precoding, which can effectively reduce the transmission power consumption of the base station; however, the higher computational complexity of multi-cell joint precoding will bring higher Signal processing power consumption; at the same time, cooperative base stations need to share user data and channel information, which will increase backbone network power consumption

In contrast, the data of each user in CoMP-CB is only sent by one base station, so the array gain of CoMP-CB precoding is low, and the transmission power consumption is large; but the lower-dimensional transmission precoding reduces the signal processing power. and because there is no need to share user data information between base stations, the backbone network has low power consumption

In addition, circuit power consumption is an important part of the total power consumption of the base station, which depends on the working state of the base station (on or dormant), and in any mode of CoMP-JP and CoMP-CB, both the macro base station and the micro base station need to be on state, which results in a large power consumption of the circuit
