HetNet Macro&Micro Co-carrier Coordination Solution Challenges
Solutions
Challenges: The gap on pilot power between Macro and Micro
Solution 1: RRC redirection/inter-frequency handover
leads to imbalance on DL/UL at Microcell edge area. (Ie. Macro Tx
( need an additional carrier F2)
Pwr= 20 W, Micro Txpwr = 5W, the GAP on DL is ~6 dB)

At Non-SHO area:
At SHO area:
Victim: Microcell Impact: Substantial RTWP rise,
Victim: Macro cell Impact: Poor UL radio link quality
UL blocking as the worse case Cause: UEs at Macro cell edge transmitting high power, perceived by Microcell as huge noise
perceived by Macro cell, causing degraded HSPA T-Put Cause: UE TxPwr is reduced as a result of Power control dominated by the Microcell
System performance risk when macro-Micro co-carrier deployment without feature
Solution 2: Triggering desensitivity, UL coverage shrinking ( if UE can not redirect to another Carrier)
