Abstract

A method for reporting uplink control information (UCI) on a user equipment (UE) is described. A set of physical downlink control channel (PDCCH) candidates on an activated serving cell are monitored. A PDCCH of a serving cell intended for the UE in a subframe is detected. A physical downlink shared channel (PDSCH) corresponding to the PDCCH in the same subframe is decoded. Transmission of the UCI for a subframe corresponding to the subframe in which the PDCCH was decoded is adjusted.
