Abstract

An apparatus of a user equipment (UE) may include a memory and one or more processors operatively coupled to the memory device. The processors determine a reporting mode for the UE based on a message received at the UE from an eNodeB. The UE may generate a channel state information (CSI) reporting message based on the determined reporting mode. The processors may also encode extra-large physical uplink control channel (xPUCCH) data including the CSI reporting message.
