APPARATUS CONFIGURED TO REPORT APERIODIC CHANNEL STATE INFORMATION ?FOR DUAL CONNECTIVITY

摘要

Embodiments of a system and method for reporting channel state information (CSI) in a wireless network are generally described herein. In some embodiments, an apparatus of a User Equipment (UE) can include physical layer circuitry to receive, in a first subframe, a first aperiodic CSI request from a first cell group, and a second aperiodic CSI request from a second cell group. The UE can include processing circuitry to determine a number of requested CSI processes corresponding to the first aperiodic CSI request and the second aperiodic CSI request. Additionally, the processing circuitry can select a subset of the requested CSI processes when the determined number of requested CSI processes is more than five. Furthermore, the processing circuitry can calculate CSI for the selected CSI processes.
