Abstract
A method includes receiving, at a user equipment, a signal including cell-specific reference signals from a number of cells. Cell-specific reference signal(s) are measured from one of the cells to determine measured result(s). The user equipment, based on the measured result(s) meeting first criteria, performs interference cancelation to cancel the cell-specific reference signal(s) corresponding to the one cell from the signal. The user equipment performs the measuring and the performing the interference cancelation for additional ones of the cells until second criteria are met. The user equipment uses measured cell-specific reference signals having their interference canceled to reduce an effect of interference from corresponding cells on communications between the user equipment and a base station. A base station may store cell search information that can be sent to the user equipment to help the user equipment perform the previous method. Apparatus, systems, computer programs, and program products are also disclosed.
