A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE communicates with a base station having a two-dimensional antenna array and receives CSI-RS signals transmitted by the two-dimensional antenna array. The UE selects the first set of CSI indicators for periodic channel CSI reporting indicating a first precoding configuration of the base station optimized to improve signal power and to reduce interference in an elevation dimension of the CSI-RS signals. The UE selects a second set of CSI indicators for periodic CSI reporting indicating a second precoding configuration of the base station optimized to improve the signal power and reduce interference in an azimuth dimension of the CSI-RS signals. The UE transmits at least one of the first set of CSI indicators and the second set of CSI indicators in a first CSI report to the base station. |
