Title:
METHODS AND APPARATUS TO CONTROL INTERFERENCE
Document Type and Number:
WIPO Patent Application WO/2014/137781
Kind Code:
A3
Abstract:
Methods and apparatus for controlling interference with regard to important control signals, e.g., synchronization signals and broadcast channel signals, are described. A configurable base station monitors for and receives signals from other base stations in its local vicinity and determines the implemented frame timings corresponding to the other deployed base stations. If possible, the configurable base station selects to use a frame timing offset which is different from the frame timing offsets being used by the other base stations. In some embodiments, symbol level and subframe level synchronization are maintained between the base stations; however, frame level synchronization may, and sometimes does vary. Different adjacent base stations may, and sometimes do, intentionally offset their frame boundaries by multiples of a subframe.
