摘要：
This paper addresses broadband radio access techniques for the Long-Term Evolution (LTE) specified as the Release 8 specifications (Rel. 8 LTE) and LTE-Advanced in the 3(rd) Generation Partnership Project (3GPP). We first briefly describe the system requirements for the Rel. 8 LTE and LTE-Advanced. Then, we describe wider transmission bandwidths around 100 MHz to satisfy the peak data rate of 1 Gbps in the downlink and 500 Mbps in the uplink for LTE-Advanced. Based on multiple access schemes and multiple-input multiple-output (MIMO) channel techniques in the Rel. 8 LTE, enhanced multiple access schemes and MTMO channel techniques for LTE-Advanced are presented to satisfy the improved system requirements while maintaining backward compatibility with the Rel. 8 LTE radio interface.
