Abstract
The present solution relates to a method in a user equipment (310) for setting up an activation time of a cell change of the user equipment (310) from a serving cell (305) to a target cell (308) in a wireless communications network (300). The user equipment (310) receives (501) a timing offset from a network controller (315), calculates (502) a cell change activation time based on the timing offset and transmits (503) the calculated activation time to the network controller (315). Then, the user equipment (310) receives (504) an approval of the cell change from the network controller (315) and moves (505) from the serving cell (306) to the target cell (308) at the activation time if the approval has been received.

7. A method in a wireless communications network for setting up an activation time of a high speed downlink shared channel cell change of a user equipment from a first cell to a second cell in a wireless communications network, the method comprising:
-
transmitting a timing offset from a network node to the user equipment through broadcast or dedicated signalling at call setup; receiving an activation time from the user equipment, the activation time indicating when the user equipment can perform a cell change from the first cell to the second cell; deciding to initiate the cell change to change the user equipment from the first cell to the second cell; configuring the first cell and the second cell with the activation time; receiving a configuration confirmation from the first cell and the second cell; and sending an approval of the high speed downlink shared channel cell change to the user equipment. - View Dependent Claims (8, 9, 10, 11)

12. A user equipment apparatus in a wireless communication network wherein the apparatus is configured to set up an activation time of a high speed downlink shared channel cell change from a first cell to a second cell, the apparatus comprising:
-
a receiver configured to receive a timing offset from the wireless communications network through broadcast or dedicated signalling at call setup; a processor configured to calculate a high speed downlink shared channel cell change activation time based on the received timing offset, the activation time indicating when the user equipment can perform a cell change from the first cell to the second cell; and a transmitter configured to transmit the calculated activation time to the wireless communications network, wherein the receiver is further configured to receive an approval of the high speed downlink shared channel cell change through the interface; and wherein the processor is further configured to perform a cell change from the first cell to the second cell at the activation time if the approval has been received. - View Dependent Claims (13, 14, 15, 16, 17)

18. A wireless communication apparatus, wherein the apparatus is capable of setting an activation time for a high speed downlink shared channel cell change of a user equipment from a first cell to a second cell in a wireless communications network, the apparatus comprising:
-
a transmitter configured to transmit a timing offset to the user equipment through broadcast or dedicated signalling at call setup; a receiver configured to receive an activation time from the user equipment, the activation time indicating when the user equipment can perform a cell change from the first cell to the second cell; and a processor configured to decide whether to initiate the cell change to change the user equipment from the first cell to the second cell and to configure the first cell and the second cell with the activation time, wherein the receiver is further configured to receive a configuration confirmation from the first cell and the second cell; and wherein the transmitter is further configured to send an approval of the high speed downlink shared channel cell change to the user equipment. - View Dependent Claims (19, 20, 21, 22)
