Abstract

The embodiments herein relate to a method in a user equipment for handling CSI in a communication system. The user equipment determines the CSI, based on information about a CPICH. The CSI comprises at least one of a CQI, a RI, a PCI and an HARQ ACK/NACK. The user equipment transmits the CSI multiplexed into a plurality of TTIs to the base station so that a first CQI-S is transmitted in one TTI and a second CQI-S or a DTX codeword is transmitted in another TTI. The second CQI-S corresponds to a second layer.
