摘要
Heterogeneous networks incorporate various small cells, such as femto cells and pico cells, in addition to a macro cell. Existing signals (e.g., PSS and SSS) configured as discovery reference signals (DRSs) may not be sufficient for a UE to discover different cells in a heterogeneous network. The disclosed aspects provide approaches for managing cell IDs for various DRS configurations to improve UE discovery of different cells in heterogeneous networks. In an aspect, a UE receives a first reference signal (e.g., based on a PCI) configured for performing a base station measurement by the UE. The UE further receives one or more second reference signals (e.g., based on a VCI which is associated with the PCI) configured for measurement by the UE. The UE performs the base station measurement based on the first reference signal and the one or more second reference signals.
