Patent ID: 8520491

Claim:
A method, comprising: determining, in an apparatus, channel state information, wherein the channel state information includes channel state information of a plurality of component carriers; and reporting, by the apparatus, the channel state information comprising a plurality of reports in an aggregated form, wherein the reporting is performed periodically via a physical uplink control channel, wherein a condition for concurrent transmission of multiple reports is formulated as follows a physical resource block index m for a k th physical uplink control channel report is formulated by m(k)=└n PUCCH (2) (k)/N sc RB ┘, where n PUCCH (2) is a higher-layer configured resource index for a periodic channel state information transmitted on the physical uplink control channel, and where N sc RB is a number of subcarriers per resource block, criteria for concurrent transmission of multiple reports is formulated by m(k)ε[b, (b+2n)], where b is an integer defined as b=min(m(k)) and nε[0, 1, . . . , N], where N is a predefined integer, m(k) is sorted in increasing order, N=1, b=min(m(k)), and starting from the smallest m(k), the criteria is checked, if the criteria is fulfilled, N is updated to N=m(k)+1 for current k.
