Abstract
An interference suppression (IS) time/frequency zone for improved interference suppression at the user equipment (UE) is provided. The IS time/frequency zone can be scheduled and set up using existing signaling of the Almost Blank Subframe (ABS) framework. This includes using the existing signaling of the ABS framework to schedule the IS time/frequency zone, coordinate transmission parameters among base stations for the IS time/frequency zone, and signal the IS time/frequency zone to the UE. In another aspect, interfering base stations align respective reference signals during the IS time/frequency zone, which allows the UE to measure the channels from its serving base station and/or the interfering base stations(s). With channel state information knowledge at the UE, interference alignment can be achieved at the UE during the IS time/frequency zone.
