The present invention is to measure a time alignment error (TAE) and / or frequency alignment error (FAE) to the antenna port belonging to a user equipment (UE) (100), transfer point devices in the cooperative multipoint transmission (CoMP) the adapted first measurement unit (110) also comprises the TAE TAE internal and / or external TAE -; And discloses a user equipment including a first feedback unit 120, adapted to feed back to the at least one transmission point device of said transfer point device for the measured internal TAE, and / or external TAE, and / or FAE have. The present invention feedback by measuring the cell-specific internal TAE and / or UE-specific external TAE / FAE by the UE in the CoMP transmission and compensate for TAE and / or FAE by the transmission point device, CoMP transmission is to be able to function properly the simple, direct and efficient approach.
