摘要： A method for communicating channel state information (CSI) to a base station is presented. The method includes identifying a number of allocated resources for CSI within at least one of a Physical Uplink Control CHannel (PUCCH) payload and a Physical Uplink Shared CHannel (PUSCH) payload. The method includes encoding channel state information (CSI) for activated carriers on a user equipment into the allocated resources for CSI. When a number of activated carriers on the user equipment is less than the number of allocated resources for CSI, the method includes using repetition encoding to duplicate the CSI for at least one of the activated carriers on the user equipment into the allocated resources for CSI.
