Toward 5G High Utilizations: A survey on OFDMA-based Resource Allocation Techniques in Next-Generation Broadband Wireless Access Networks

Abstract

LTE is marketed as 4G standard for wireless communication services. LTE network technologies provide a high speed triple play services like data, voice, and video with QoS provision. The resource allocation techniques primary concerns are the QoS support that aims to satisfy the diverse service requirements as well as to guarantee the required data rates from the available resources. In this context different network architecture for broadband wireless data network like LTE made OFDMA a practical access technology for wireless multimedia services. Therefore, this survey investigates the techniques that aim to support QoS for real-time and non real-time services in OFDMA-based packet scheduling and adaptive multiuser frequency-time domain resource allocation. Moreover, this survey addressed the different aspects of resource allocation algorithms design to be contributed to the emerging 5G next generation networks.
