Resource allocation schemes in 5G: survey and challenges

Abstract

In telecommunications, 5G is the fifth-generation of mobile networks with the enhanced features of higher data rates, lower power consumption, and extremely reduced latency over 4G. The spatial resource reused by 5G networks which is to facilitate customers with desired Quality of Service (QoS) by developing small cells into the coverage of macro cells. However, there is limited spectrum reuse and mutual interference among different users, an efficient Resource Allocation (RA) algorithm is required to reduce interference and to attain spectrum sharing. Many existing technologies have been proposed to solve some of the 5G challenges. In this paper, various resource allocation algorithms are analyzed and identify the challenging issues on where to focus attention for future research work.
