## Abstract

A method 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 method including 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, and performing a power measurement of a pilot signal from a cell that is included in the E-DCH active set.

## Claims

### Claim 1

A 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 configured to perform measurements of a first, non-active E-DCH but active DCH, pilot signal from a first cell that is not included in the E-DCH active set but is included in the DCH active set, and to perform measurements of a second, active E-DCH, pilot signal from a second cell that is included in the E-DCH active set, wherein an event is triggered when the non-active E-DCH but active DCH pilot signal becomes better than the active E-DCH pilot signal; and
a circuit configured to send, to a communications node, a measurement report comprising said measurements;
wherein the E-DCH active set is updated based on the measurements.

### Claim 2

A method of a user equipment for a mobile communication system, the mobile communication system defining a dedicated channel (DCH) active set comprising at least one cell and an enhanced-dedicated channel (E-DCH) active set comprising at least one cell, the method comprising:
performing a measurements of a first, non-active E-DCH but active DCH, pilot signal from a first cell that is not included in the E-DCH active set but is included in the DCH active set and measurements of a second, active E-DCH, pilot signal from a second cell that is included in the E-DCH active set, wherein an event is triggered when the non-active E-DCH but active DCH pilot signal becomes better than the active E-DCH pilot signal;
sending, to a communications node, a measurement report comprising said measurements; and
updating the E-DCH active set based on the measurements.

### Claim 3

A communications node 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 communications node comprising:
a circuit configured receive, from a user equipment, a measurement report comprising measurements performed by the user equipment of a first, non-active E-DCH but active DCH, pilot signal from a first cell that is not included in the E-DCH active set but is included in the DCH active set, and measurements performed by the user equipment of a second, active E-DCH, pilot signal from a second cell that is included in the E-DCH active set, wherein the measurement report is received when an event has been triggered by the non-active E-DCH but active DCH pilot signal becoming better than the active E-DCH pilot signal; and
a circuit configured to update the E-DCH active set based on the measurements.

### Claim 4

A method of a communications node 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 method comprising:
receiving, from a user equipment, a measurement report comprising measurements performed by the user equipment of a first, non-active E-DCH but active DCH, pilot signal from a first cell that is not included in the E-DCH active set but is included in the DCH active set, and measurements performed by the user equipment of a second, active E-DCH, pilot signal from a second cell that is included in the E-DCH active set, wherein the measurement report is received when an event has been triggered by the non-active E-DCH but active DCH pilot signal becoming better than the active E-DCH pilot signal; and
updating the E-DCH active set based on the measurements.
