摘要：LTE Advanced has brought revolution in the field of wireless communication technology by providing high data rates of up to 1Gbps. There is a need of increased data rates these days that may support the delivery of richer mobile multimedia contents to the end users. Rate adaptation is one of the key enabling technology in the success of LTE Advanced that has cited attraction of academia and research communities in recent years. Rate adaptation is the determination of the optimal data transmission rate most suitable for current prevailing wireless channel conditions. To maximize the performance of wireless devices, it is important to select the best appropriate rate hence rate adaptation algorithms (RAA's) are required. This work includes a comprehensive survey on various types of RAA's in LTE-A for effective resource utilization. Depending on the channel conditions various performance parameters such as throughput, power consumption and latency have been studied. It has been observed from the literature survey that many proposals have been published on LTE-A. Sill there is a need of research to be carried in LTE-A as this technology is not fully matured so open issues and future scope are also raised in this work.
