Method and device for energy-efficient transmission of treatment data in heterogeneous network

Abstract

The embodiment of the invention provides a method and a device for energy-efficient transmission of treatment data in a heterogeneous network. A specific execution mode of the method comprises the following steps of: determining current operation attribute information of the heterogeneous network; according to the current operation attribute information of the heterogeneous network, selecting a transmission mode suitable for the heterogeneous network from a plurality of preset transmission modes, wherein the plurality of preset transmission modes include a single macro base station MBS mode, a single micro base station mBS mode, a single collaborated multi-point joint processing CoMP-JP mode, a mixed mode of any two of the three modes and a mixed mode of the three modes; and transmitting data in the heterogeneous network with the determined transmission mode. According to the execution mode, energy consumption of base stations can be reduced, and energy utilization rate of the heterogeneous network can be improved.

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, an
