Abstract
Examples are described relating to methods, apparatus and computer programs for configuring a user equipment in a cellular wireless network. Certain exemplary methods involve receiving (440), at the user equipment (430), control information regarding one or more of a plurality of channel-state information (CSI) reference signals. The plurality of CSI reference signals are receivable by the user equipment (430) from one or more of a plurality of antenna ports that form part of the cellular wireless network, the plurality of CSI reference signal being associated with corresponding antenna ports. The control information is for use in configuration of the user equipment (430) and is received over a radio communications downlink from a node (410) in the cellular wireless network. If estimation of one or more radio communication channels at the user equipment (430) is configured (450) based on the received control information, improvements in demodulation and CSI feedback are achieved.
