Anchor base station, slave cell and user equipment

1. A mobile telecommunications system anchor base station for a mobile telecommunications system including at least one anchor cell and at least one slave cell being associated with the anchor cell, the anchor base station comprising circuitry being configured to:

partially activate or deactivate the slave cell, based on a service requirement received from at least one user equipment;

activate or deactivate a partial carrier, wherein the partial carrier is activated or deactivated for a single user equipment or a group of user equipments in the slave cell; and

to perform handover on the basis of a relayed handover message being transmitted to the slave cell and being relayed by the slave cell, wherein the slave cell is a virtual cell.

2. The mobile telecommunications system anchor base station of claim 1 , wherein the service requirement is received from a group of user equipments.

3. The mobile telecommunications system anchor base station of claim 1 , wherein the service requirement includes application level information.

4. The mobile telecommunications system anchor base station of claim 1 , wherein the circuitry is further configured to send a one-shot activation command.

5. The mobile telecommunications system anchor base station of claim 4 , wherein the circuitry is configured to send the one-shot activation command to the slave cell or a group of user equipments.

6. The mobile telecommunications system anchor base station of claim 1 , wherein the circuitry is further configured to select a coordinated set based on at least one of: link quality, matched service requirement, service provider, resources availability and interference level.

7. A slave cell being established by a slave base station and being connected to an anchor base station in a mobile telecommunications system, the mobile telecommunications system comprising the anchor base station, the anchor base station being configured to communicate with at least one user equipment and at least one further slave cell, the at least one further slave cell being configured to communicate with at least one user equipment and the anchor base station, the slave cell comprising circuitry being configured to:

activate or deactivate a partial carrier, based on a service requirement, wherein the partial carrier is activated or deactivated for a single user equipment or a group of user equipments in the slave cell; and

to perform handover on the basis of a relayed handover message being transmitted to the slave cell and being relayed by the slave cell, wherein the slave cell is a virtual cell.

8. The slave cell of claim 7 , wherein the service requirement includes application level information.

9. A user equipment being connectable to at least one anchor base station and at least one slave cell of a mobile telecommunications system, the mobile telecommunications system comprising the anchor base station being configured to communicate with at least one user equipment and at least one slave cell, the at least one slave cell being established by a slave base station and being configured to communicate with at least one user equipment and the anchor base station, the user equipment comprising a circuitry being configured to:

receive a carrier segment activation command or deactivation command, the carrier segment activation command or deactivation command being for partial carrier resources, wherein the partial carrier resources are activated or deactivated for a single user equipment or a group of user equipments in the slave cell; and

to perform handover on the basis of a relayed handover message being transmitted to the slave cell and being relayed by the slave cell, wherein the slave cell is a virtual cell.

10. The user equipment of claim 9 , wherein the circuitry is further configured to measure and report a channel quality only on activated resource blocks.

11. The user equipment of claim 9 , wherein the circuitry is further configured to receive a user equipment group specific reference signal only on activated resource blocks.
