In one embodiment, for example, an apparatus for a base station is provided that includes a radio interface and a processor coupled to the radio interface. The processor is configured to receive a channel quality indicator (CQI) index, wherein the CQI index is based on a channel state information (CSI) reference resource, further wherein a first three orthogonal frequency-division multiplexing (OFDM) symbols of the CSI reference resource are occupied by control signals, select a modulation and coding scheme (MCS) for a physical downlink shared channel (PDSCH) based on the CQI index, and cause transmission of the PDSCH based on the selected MCS via the radio interface.
