Problems solved by technology

[0005] Most of the current research work discusses the hybrid energy supply technology and the H-CRAN architecture separately, and few studies combine the two technologies. In addition, most of the existing research is based on the fact that the state of the environment is completely known. Does not take into account the time-varying wireless network environment

Embodiment Construction

[0043] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] see figure 1 , figure 1 It is a schematic diagram of the H-CRAN network architecture scenario for hybrid energy supply in the present invention. In the embodiment of the present invention, a downlink transmission scenario of an H-CRAN network architecture is considered, and both renewable energy and traditional electric energy are used for power supply in the system. Among them, the macro base station is powered by the electricity purchased from the power company, and the RRHs are considered to be powered by a hybrid energy consisting of renewable energy and purchased electricity. Consider that the system works in discrete time slots t, t∈{1,2,...,T}, where each time slot t represents a scheduling period ΔT with equal intervals. It is assumed that there is a macro base station and S RRHs for data transmission in the entire H-CRAN ...

Abstract

The invention relates to a hybrid energy supply-oriented resource allocation and energy management method under an H-CRAN network architecture, and belongs to the technical field of mobile communication. In this method, on each discrete time slot, cross-layer interference, system stability and energy sustainability of users are considered. On the premise of ensuring the lowest service quality requirement of each type of users, the average time delay constraint of the user queue and the sustainability of the energy queue; appropriate wireless resources are allocated to the users served by eachservice provider according to the state information of the current time slot of the user equipment, and each base station performs energy management according to the current environment state information so as to perform dynamic resource allocation and energy management by taking maximization of the average net income of the service provider as a target. According to a dynamic resource allocationand energy management method provided by the invention, the average net income of the service provider can be improved, and meanwhile, the system data queue delay demand, the energy queue sustainability and the service quality demand of the user can be maintained.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and relates to a resource allocation and energy management method under the H-CRAN network architecture oriented to hybrid energy supply. Background technique [0002] In the coming 5G era, the data service transmission rate of a single link will reach 10Gbit / s, the frequency and power efficiency need to be increased by 10 times, the throughput per unit area of ​​network coverage will be increased by 25 times, and the number of single-node access users will increase 10-100 times, the end-to-end service delay needs to be shortened to 1ms, and the service life of the terminal battery will be extended by 10 times. In order to support the performance requirements proposed by 5G, a new 5G wireless network architecture is required. It is worth noting that H-CRAN is an effective solution. [0003] The H-CRAN architecture is a network architecture that combines the control plane and servic...
