Abstract
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.
Claims29
A method comprising:
- receiving, by a wireless device and from a base station, a physical uplink control channel (PUCCH) configuration of the wireless device, wherein the PUCCH comprises a first set of PUCCH resource blocks in a time interval and a second set of PUCCH resource blocks overlapping in time in the time interval with the first set of PUCCH resource blocks, and wherein the first set of PUCCH resource blocks comprises a smaller number of resource blocks than the second set of PUCCH resource blocks;
- determining, by the wireless device and based on first signals received via a first plurality of cells, a plurality of channel state information (CSI) reports for transmission via the time interval;
- selecting, by the wireless device, the first set of PUCCH resource blocks for transmission of at least one first CSI report of the plurality of CSI reports;
- selecting, by the wireless device, based on a size of at least one second CSI report of the plurality of CSI reports, based on a number of resource blocks of the first set of PUCCH resource blocks, and based on a number of resource blocks of the second set of PUCCH resource blocks, the second set of PUCCH resource blocks for transmission of the at least one second CSI report of the plurality of CSI reports;
- transmitting, via the first set of PUCCH resource blocks, the at least one first CSI report;
- and
- transmitting, via the second set of PUCCH resource blocks and overlapping in time with the transmission of the at least one first CSI report, the at least one second CSI report.
