Abstract:
1. User equipment for a mobile communication system, the mobile communication system defining a dedicated channel (DCH) active set and an enhanced-dedicated channel (E-DCH) active set, the user equipment comprising: a circuit for receiving information as to which cell is to be in the E-DCH active set, wherein said information is transmitted from a radio network controller in the mobile communication system; a circuit for performing a power measurement of a pilot signal from a cell that is not included in the E-DCH active set but included in the DCH active set after the information is received; a circuit for performing a power measurement of a pilot signal from a cell that is included in the E-DCH active set after the information is received; and a circuit for sending information on the power measurement of the pilot signal from the cell that is not included in the E-DCH active set but included in the DCH active set and the pilot signal from the cell included in the E-DCH active set, wherein a same cell that is not included in the E-DCH active set but included in the DCH active set, is replaced in the E-DCH active set after sending the information on the power measurement of the pilot signal from the cell that is not included in the E-DCH active set but included in the DCH active set and the pilot signal from the cell included in the E-DCH active set.
