• U-plan: 5ms (unload, small IP packet), RTT<10ms
> 容量
• <5MHz: 200 subs 激活
• >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)
