TRANSMISSION OF UPLINK CONTROL INFORMATION IN CARRIER AGGREGATION WITH A LARGE NUMBER OF CELLS

摘要

Methods and apparatus are provided for a user equipment (UE) to transmit uplink control information (UCI) and for a base station to receive UCI when the UE is configured a number of cells for operation with carrier aggregation (CA). The base station configures the UE a code rate and the UE determines a UCI payload to transmit in a subframe to be the maximum one that results a transmission code rate that is not larger than the configured code rate. For transmission of aperiodic channel state information (A-CSI), a number of triggering states depends on the number of cells.
