CCIPC Phase I and Phase II
Mass low rate users in cell
Strong interference from control channel
CCPIC is Control Channel Parallel Interference Cancellation
• Large number of low rate users in one cell brings
strong interference• Cell capacity gravely falls due to strong interferences
by large number of users
Uplink Capability Challenges Reducing the Interference of Control Channel

32 1
User 2 and 3 are interferences for user 1
Interferences of 2 and 3 are removed before demodulation of 1
VSFeature off Feature on
• CCPIC phase I support cancellation in one base-band board• CCPIC phase II support cancellation in whole cell
Huawei is the ONLY vendor that realize CCPIC with self-design chipset
