LTE-Advanced Performance and Future Developments
LTE Release 8 incorporates the latest advances in radio technology and has attracted global industry support. Intensive field trials conducted by equipment vendors and network operators have confirmed the high performance of LTE, and commercial services using LTE were first launched in December 2009. Many leading operators worldwide have committed to deploying LTE, and the roll-out of LTE is expanding and accelerating.
LTE Release 9 brings enhancements and performance improvements in a number of aspects, including Home eNodeBs, MBMS, location services and MIMO. For Release 10 and beyond (LTE-Advanced), the standardization activities in 3GPP were aligned with the IMT-Advanced standardization process in ITU-R1 to meet future demands for continuous improvement of system performance and satisfy the constantly increasing expectations and demands of the consumers. It was confirmed that LTE-Advanced fully satisfies the requirements set by ITU-R, and LTE-Advanced was therefore accepted as an IMT-Advanced technology. This chapter provides a summary of the system performance achievable with LTE-Advanced using the Release 10 version of the specifications, followed by a discussion of future developments beyond Release 10.
32.1 LTE-Advanced System Performance
As listed in Table 27.1, ITU-R specified eight items as the minimum requirements for IMT-Advanced:
1. Peak spectral efficiency;
2. Cell spectral ...
