Abstract: In this talk we first provide a detailed tutorial overview of the PHY layer procedures, techniques and features in LTE and their evolution towards LTE-Advanced (Rel. 8-10). We will start with the revision of the fundamental basics of LTE, including the LTE frame structure for TDD and FDD, the reference and synchronization signal and the physical channels in uplink and downlink, as well as the synchronization, Random Access and HARQ procedures. We will further address the most important LTE PHY layer system blocks and requirements both from the base station (eNB) and user equipment (UE) perspective. Finally, we provide a detailed overview on the available channel state feedback mechanism and reporting schemes devised in LTE and LTE-A that enable efficient channel aware scheduling and multi-antenna operation. Furthermore, based on the above, we will discuss here in great details the implications of the standardization work onto the PHY layer design. In this talk will specifically focus on multi-antenna techniques that are supported in LTE and illustrate the implementational aspect associated with these schemes. We will outline how multi-antenna techniques for interference mitigation have evolved in the LTE standard from merely interference randomization types of open-loop approaches in LTE towards powerful interference coordination and interfere suppression types of closed-loop schemes in LTE-Advanced.
