Abstract:
A system and method may provide user equipment (UE)-implemented inter-cell interference mitigation. In some implementations, a method in a user equipment for Hybrid Automatic Repeat Request (HARQ) indicator determination includes separating received Physical HARQ Indicator Channel (PHICH) modulation symbols into two data streams: (1) PHICH modulation symbols including interference from Cell-specific Reference Symbol (CRS) transmissions, and (2) PHICH modulation symbols including substantially no interference from the CRS transmissions. The UE separately evaluates the PHICH modulation symbols including interference and the PHICH modulation symbols including substantially no interference. The UE determines a Hybrid ARQ indicator based upon a combination of the separate evaluations of the PHICH modulation symbols including interference and the PHICH modulation symbols including substantially no interference.
