Methods and apparatuses are described for improving identification of reference signal transmissions at a user equipment (UE). One or more restrictions related to reference signal transmissions in one or more interfering signals can be identified. One or more reference signal transmissions received in the one or more interfering signals can then be detected based at least in part on the one or more restrictions. The one or more reference signal transmissions received in the one or more interfering signals can be processed to improve communications with a serving base station.
