The 3GPP Long Term Evolution Advanced (LTE-A) system, as compared to the LTE system. is anticipated to include several new features and enhancements, such as the usage of channel bandwidth beyond 20 MHz (up 100 MHz). higher order Multiple input multiple Output (MIMO) for both downlink and uplink transmissions, larger capacity especially for cell edge user equipment, and voice over IP (VoIP) users, and wider coverage and etc. This paper presents some key enabling technologies including flexible uplink access schemes, advanced uplink MIMO receiver designs, cell search. adaptive hybrid ARQ, and multi-resolution MIMO precoding. for the LTE-A system.
