Abstract—To meet the rapidly growing IP data traffic cost-effectively and to improve cell-edge performance, 3GPP is working on the evolution of Release 8 LTE called LTE-Advanced. LTE Advanced is introduced in Release 10 of 3GPP, and details of some of its features would be specified in Release 11 and beyond. LTE-Advanced is designed to meet or exceed the requirements of IMT-Advanced such as the support for the data rate of 1 Gbps and bandwidths up to 100 MHz. LTE-Advanced system is backward compatible with LTE [1] This paper provides a technical overview of LTE-Advanced, describing the features such as carrier aggregation, enhanced advanced antenna techniques for the DL and the UL, relays, and coordinated multipoint (CoMP) transmission and reception. Release 9 (R9) features such as location services (LCS) and eMBMS are also discussed. In summary, this paper provides a technical overview of R10 and beyond. Some of the key features of LTE Advanced will be Worldwide functionality & roaming, Compatibility of services, Interworking with other radio access systems and Enhanced peak data rates to support advanced services and applications (100 Mbit/s for high and 1 Gbit/s for low mobility). The IMT-Advanced systems will support low to high mobility applications and wide range of data rates, in accordance with service demands in multiuser environment. This paper provides a brief insight in to the LTE-Advanced standards and its key requirements which will be a pathway to next generation of wireless communication or 4G [2].
