Abstract:
A user equipment (UE) for reporting uplink control information (UCI) when one or more Licensed-Assisted Access (LAA) serving cells are configured is described. The UE includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to determine if physical uplink shared channel (PUSCH) transmissions are scheduled on LAA serving cells and licensed cells. The instructions are also executable to determine a type of UCI to be reported. The instructions are further executable to determine a channel and cells to carry different UCI. The instructions are additionally executable to transmit the channel on the cells determined to carry UCI. The instructions are also executable to determine whether a LAA PUSCH is transmitted and UCI is multiplexed. The instructions are further executable to drop LAA PUSCH or transmit LAA PUSCH subject to listen-before-talk (LBT).
