Claim of US Patent No. 10,925,089

1. A user terminal which performs communication using cells including a licensed assisted access (LAA) cell which applies listening before uplink (UL) transmission, the user terminal comprising:a transmitter that transmits uplink control information and uplink data; and
a processor that controls transmission of the uplink control information and the uplink data,
wherein the processor performs control to transmit the uplink control information using an uplink channel other than an uplink shared channel of the LAA cell,
wherein the user terminal is configured to define a user equipment (UE) capability information comprising a UE capability for UL-LAA defined separately from a UE capability of simultaneous transmission of the uplink control channel and the uplink shared channel between the cells including the LAA cell, and
wherein when simultaneous transmission of a licensed band uplink control channel and the uplink shared channel of the LAA cell is supported the processor performs control to report the UE capability information.
