A user equipment (UE) in communication with a base station is configured by the base station for operation with an adapted time division duplex (TDD) uplink-downlink (UL-DL) configuration. A process enables UL power control for transmissions of various channels or signals from the UE in two different sets of UL transmission time intervals (TTIs) and a process enabling receptions of data transport blocks by the base station in two different sets of UL TTIs.
