Problems solved by technology

In "Computer Engineering and Design", Volume 38, Issue 1, "Load Balancing Strategy Based on D2D Communication Mechanism in Heterogeneous Networks", an optimal relay selection method based on power consumption is proposed, which can effectively reduce the relay link The overall power consumption problem, but it does not consider the power consumption ratio of relay users in the entire link. The higher power consumption ratio is unfair to relay users
At the same time, the uplink of the relay user accesses the small base station based on the minimum signal to interference plus noise ratio (SINR) criterion, so that the users in the dormant area will centrally access the surrounding base stations through different relay users , so that the load of the surrounding base stations is unbalanced

Abstract

The invention discloses a method for selecting an energy-saving transfer path based on D2D relay for a user terminal in a heterogeneous network. The relay link is classified and selected by distinguishing the network type to which the relay user belongs. When selecting macro base station users as relays, use the method of minimum relay power consumption ratio to control the power consumption ratio of macro relay users while ensuring the lowest total power consumption of relay links; select small base station users as relays When , under the condition of ensuring the minimum energy consumption required for the normal communication of the link, the method of minimum relay power consumption ratio is adopted to reduce the power consumption of relay users, and at the same time adjust the effective rate of uplink of relay users of small base stations, Balance the load of relay users accessing surrounding small base stations. The present invention controls the total power consumption of the relay link under the condition of satisfying the normal communication of the user, reduces the power consumption of the user terminal and balances the load of the surrounding receiving base stations, and is suitable for the real-time communication system.

Description

technical field [0001] The present invention relates to a method for selecting a transfer path of a user end during a dormant process of a base station, in particular to an energy-saving transfer path of a user end based on a device-to-device (D2D) relay during a dormant process of a small base station in a heterogeneous network The selection method belongs to the technical field of wireless communication. Background technique [0002] In recent years, under the condition of increasingly tight spectrum resources, in order to meet people's growing demands on the capacity and coverage of mobile communication networks, the deployment of small base stations in heterogeneous networks has become more and more dense, which has resulted in huge Network power consumption. With the rise of the concept of green communication, the base station dormancy method can effectively optimize the above problems. According to the "tide" phenomenon of users, it can reasonably transfer users and t...
