A system comprising: an enhanced Node B, eNode B, comprising: means for determining a channel quality indicator, CQI, configuration for a user equipment, UE, the CQI configuration indicating a priority for channel state information, CSI, reports to be sent by the UE for periodic reporting on a physical uplink control channel, PUCCH, in a subframe, each of the plurality of CSI reports being related to a respective one of a plurality of component carriers and each of the plurality of component carriers having an associated priority; means for transmitting the CQI configuration to the UE; the UE comprising: means for receiving the CQI configuration from the eNode B; means for determining, based on the CQI configuration, whether at least two of a plurality of channel state information, CSI, reports are to be transmitted, and on a condition that the determination is positive, dropping at least one lower priority CSI report of the plurality of CSI reports, wherein: a CSI report containing a Rank Indicator, RI, is prioritized over one or more CSI reports containing a Channel Quality Indicator, CQI, and a CSI report containing a RI for a component carrier with a highest associated priority is prioritized over one or more CSI reports containing a RI for a respective component carrier of lower associated priority; and means for transmitting, subsequent to the dropping, at least one prioritized CSI report of the plurality of CSI reports on the PUCCH in the subframe to the eNode B. means for determining a channel quality indicator, CQI, configuration for a user equipment, UE, the CQI configuration indicating a priority for channel state information, CSI, reports to be sent by the UE for periodic reporting on a physical uplink control channel, PUCCH, in a subframe, each of the plurality of CSI reports being related to a respective one of a plurality of component carriers and each of the plurality of component carriers having an associated priority; means for transmitting the CQI configuration to the UE; the UE comprising: means for receiving the CQI configuration from the eNode B; means for determining, based on the CQI configuration, whether at least two of a plurality of channel state information, CSI, reports are to be transmitted, and on a condition that the determination is positive, dropping at least one lower priority CSI report of the plurality of CSI reports, wherein: a CSI report containing a Rank Indicator, RI, is prioritized over one or more CSI reports containing a Channel Quality Indicator, CQI, and a CSI report containing a RI for a component carrier with a highest associated priority is prioritized over one or more CSI reports containing a RI for a respective component carrier of lower associated priority; and means for transmitting, subsequent to the dropping, at least one prioritized CSI report of the plurality of CSI reports on the PUCCH in the subframe to the eNode B. means for receiving the CQI configuration from the eNode B; means for determining, based on the CQI configuration, whether at least two of a plurality of channel state information, CSI, reports are to be transmitted, and on a condition that the determination is positive, dropping at least one lower priority CSI report of the plurality of CSI reports, wherein: a CSI report containing a Rank Indicator, RI, is prioritized over one or more CSI reports containing a Channel Quality Indicator, CQI, and a CSI report containing a RI for a component carrier with a highest associated priority is prioritized over one or more CSI reports containing a RI for a respective component carrier of lower associated priority; and a CSI report containing a Rank Indicator, RI, is prioritized over one or more CSI reports containing a Channel Quality Indicator, CQI, and a CSI report containing a RI for a component carrier with a highest associated priority is prioritized over one or more CSI reports containing a RI for a respective component carrier of lower associated priority; and means for transmitting, subsequent to the dropping, at least one prioritized CSI report of the plurality of CSI reports on the PUCCH in the subframe to the eNode B.
