A physical uplink control channel (PUCCH) may comprise a plurality of sets of PUCCH resource blocks overlapping in time in a time interval. A plurality of channel state information (CSI) reports may be used for transmission via the PUCCH resource blocks overlapping in time in the time interval. Selection of at least one CSI report for transmission may be based on a size of the CSI report and on numbers of blocks in the sets of PUCCH resource blocks.
