LTE is widely used mobile communication technology. Long Term Evolution (LTE) standard is conceived as an all IP network to achieve higher data rate, low latency, scalable bandwidth, mobility and extended coverage. The network guarantees Quality of Service (QoS) for diverse applications such as VoIP, video and web browsing according to the Third Generation Partnership Project (3GPP) specifications. The Radio Resource Management (RRM) techniques such as packet scheduling algorithm play a vital role in providing such guarantees. The LTE introduces enhanced data link mechanisms to support successful implementation of new data services across the network. This paper presents a survey of downlink scheduling algorithms. The following scheduling algorithms are considered: Round Robin, Proportional Fair, Best CQI, Resource Fair and MaxMin. The comparative analysis of these algorithms is also presented.
