Abstract:
1. A wireless user equipment device for communicating with a base transceiver station of a radio network, the wireless user equipment device comprising: a receiver configured to receive from the base transceiver station data on a first downlink carrier and on a second downlink carrier, to determine values of a first channel quality indicator for the first downlink carrier, and to determine values of a second channel quality indicator for the second downlink carrier, one value of the first channel quality indicator per time slot, one value of the second channel quality indicator per time slot; a transmitter configured to transmit on a first uplink carrier to the base transceiver station channel quality indicator values in a CQI field, one CQI field per time slot; and a processing circuit coupled to the receiver and to the transmitter, the processing circuit being configured to encode the CQI field for each time slot of a first plurality of time slots with (1) a value derived from the value of the first channel quality indicator corresponding to said each time slot of the first plurality of time slots, and (2) a value derived from the value of the second channel quality indicator corresponding to said each time slot of the first plurality of time slots, so that the CQI field transmitted on the first uplink carrier conveys information regarding channel quality of the first downlink carrier and information regarding channel quality of the second downlink carrier for said each time slot of the first plurality of time slots, wherein the CQI field includes both the first channel quality indicator and the second channel quality indicator for the first downlink carrier and the second downlink carrier in a single time slot.
