Claim of US Patent No. 9,967,863

1. A user equipment (UE) comprising:a processor; and
memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:
configure with a secondary cell group (SCG);
configure with a licensed-assisted access (LAA) serving cell as a primary secondary cell (pSCell) of the SCG;
receive a physical downlink shared channel (PDSCH) on at least one LAA serving cell in the SCG;
determine a channel to carry uplink control information (UCI), the channel being on a serving cell in the SCG;
determine transmission timing of the channel based on reception timing of the received PDSCH, wherein the transmission timing comprises a starting subframe and an allowed UCI transmission range when an LAA is used for UCI reporting;
determine one or more PDSCHs of which hybrid automatic repeat request acknowledgment (HARQ-ACK) bits are included in the UCI, the one or more PDSCHs including the received PDSCH;
determine content of the HARQ-ACK bits; and
perform a channel access procedure for transmission of the channel.
