Patent ID: 11343850

Abstract:
The present disclosure provides a method and a device in a User Equipment (UE) and a base station. The UE transmits M2 first type radio signal(s) in M2 time block(s) of M1 time blocks respectively, and transmits a second type radio signal; the second type radio signal is used to determine at least the former of the M2 time block(s) and M2 first type carrier(s); the M2 first type radio signal(s) is(are) transmitted on the M2 first type carrier(s) respectively; a first bit block is used to generate the M2 first type radio signal(s); the present disclosure designs the second type radio signal, which helps the base station determine a position of a carrier where transmission is actually performed and corresponding time block when narrowband UE performs uplink data transmission on unlicensed frequency spectrum. This further streamlines base station reception and improves uplink transmission performance.
