Abstract: Methods, systems, and devices are described for identifying channel state information reference signals (CSI-RS) from a non-serving cell in a wireless communications network. A subset of virtual cell identity (VCID) candidates may be identified, and one or more CSI-RS locations for one or more CSI-RS in a received signal from a non-serving cell may be determined The CSI-RS locations may be determined based on periodicity properties of CSI-RS transmissions of the subset of VCID candidates. The one or more determined locations in the received signal may be used to identify the one or more CSI-RS in the received signal through searching the locations for all available VCIDs in a set of VCIDs.

Abstract: 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.
