Uplink control information piggybacking in wireless systems

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control message from a base station. The downlink control message may include a grant for communication with the base station and an indication of a component carrier (CC) to use for transmission of uplink control information (UCI). The UE may determine a CC for UCI transmission based at least in part on the CC indication, and the UE may transmit an uplink message including the UCI via the determined CC.
