Advanced <strong>MIMO</strong> Techniques <strong>in</strong> UL<br />
• Introduction of SU-<strong>MIMO</strong> up to 4-stream<br />
transmission<br />
– Rel. 8 LTE does not support SU-<strong>MIMO</strong><br />
– Satisfy peak SE requirement (i.e., 15 bps/<br />
Hz)<br />
• Introduction of UL transmit diversity for<br />
PUCCH<br />
