User equipments, base stations and methods

An evolved node B (eNB), comprising:

• a higher-layer processor configured to configure, in a user equipment (UE), one or more License Assisted Access (LAA) serving cells and one or more non-LAA serving cells;
• a physical downlink shared channel (PDSCH) transmitter configured to transmit one or more PDSCHs;
• a physical uplink control channel (PUCCH) receiver configured to receive a PUCCH on a pre-determined one of the non-LAA serving cells;
• and
• a physical uplink shared channel (PUSCH) receiver configured to receive one or more PUSCHs;
• wherein
• uplink control information (UCI) of the PDSCH on any of the non-LAA serving cells is carried by either of the PUCCH and the PUSCH on one of the non-LAA serving cells, and
• UCI of the PDSCH on any of the LAA serving cells is carried by either of the PUCCH, the PUSCH on one of the non-LAA serving cells, or the PUSCH on one of the LAA serving cells.

A method for a user equipment (UE), comprising:

• configuring one or more License Assisted Access (LAA) serving cells and one or more non-LAA serving cells;
• receiving one or more physical downlink shared channels (PDSCHs);
• transmitting a physical uplink control channel (PUCCH) on a pre-determined one of the non-LAA serving cells;
• and
• transmitting one or more physical uplink shared channels (PUSCHs);
• wherein
• uplink control information (UCI) of the PDSCH on any of the non-LAA serving cells is carried by either of the PUCCH and the PUSCH on one of the non-LAA serving cells, and
• UCI of the PDSCH on any of the LAA serving cells is carried by either of the PUCCH, the PUSCH on one of the non-LAA serving cells, or the PUSCH on one of the LAA serving cells.
