The DCI can contain a Channel State Information (CSI) request on a physical control channel in a subframe of a first serving cell. The CSI request can direct the UE to perform CSI measurements for at least one aperiodic Channel State Information Reference Signal (CSI-RS) of a second serving cell. The UE can ascertain CSI-RS resources in a subframe of the second serving cell based on at least the DCI contents. The UE can determine CSI based on the ascertained CSI-RS resources. The UE can send the determined CSI to the base station."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for signaling aperiodic channel state indication reference signals for LTE operation","description":"A User Equipment (UE) can receive Downlink Control Information (DCI) from a base station.
