User equipments, base stations and methods for uplink transmission
A user equipment (UE) is described. The UE includes receiving circuity configured to receive a radio resource control (RRC) message comprising a first parameter used for configuring a periodicity. The receiving circuitry is also configured to receive a RRC message comprising a second parameter used for configuring a number of repetitions. The UE also includes transmitting circuitry configured to perform, based on the first parameter and the second parameter, repetitions of transmissions of a transport block. The UE is not expected to be configured with the number of repetitions larger than the number of slots within the period.
