LTE 空中接口技术与性能_系统概述

LTE性能设计目标 > TR25.913 > 峰值速率 • 下行100Mbps（20MHz，MIMO2x2) • 上行50Mbps(20MHz, 1x antenna) > 时延 • C-plan • U-plan: 5ms (unload, small IP packet), RTT 容量 • 5MHz: >400 subs > Throughput • 3-4 times better than release 6 (DL ) • 2-3 times better than release 6 (UL ) > Spectrum Efficiency • 3-4 times better than release 6 (DL ) • 2-3 times better than release 6 (UL ) > Increase the support of QoS for the various types of services (e.g. Voice over IP)
