According to an aspect, a wireless device is configured to report, to a base station, channel quality information (CQI) using a predetermined set of CQI index values, where each CQI index value is interpreted by the wireless device and the base station as corresponding to a combination of modulation and coding rate. The wireless device determines, based on a downlink signal configuration, that a first one of the CQI index values corresponds to no modulation and coding rate that can be used for transmissions to the wireless device from the base station. The wireless device transmits the first CQI index value to the base station to signal information other than a combination of modulation and coding rate. The base station receives the first CQI index value and interprets it to signal information other than a combination of modulating and coding rate.
