Abstract

Claims (24)

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

obtain geolocation information of a user equipment for determining whether a specific beam of a plurality of possible beams is suitable for the user equipment being located at a location identified by the geolocation information;

when the user equipment is in a radio resource control connected state, transmit system information based on beam information, wherein the beam information identifies the specific beam to be used to transmit data to the user equipment; and

transmit user plane cell specific system information or control plane cell specific information, including scheduling information indicating a broadcast schedule for the specific beam.

2. The mobile telecommunications system anchor base station of claim 1 , wherein the system information includes the beam information.

3. The mobile telecommunications system anchor base station of claim 1 , wherein the beam information further includes a coverage information of a beam.

4. The mobile telecommunications system anchor base station of claim 1 , wherein the beam information further includes line of sight information.

5. The mobile telecommunications system anchor base station of claim 1 , wherein the geolocation of the user equipment is obtained by receiving the geolocation information from the user equipment.

6. The mobile telecommunications system anchor base station of claim 1 , wherein the geolocation information of the user equipment is obtained by measurement of a reference signal received from the user equipment.

7. The mobile telecommunications system anchor base station of claim 1 , wherein the circuitry transmits the system information upon receipt of the geolocation information of the user equipment.

8. The mobile telecommunications system anchor base station of claim 1 , wherein the beam information includes information about the specific beam and other beams of the plurality of possible beams.

9. The mobile telecommunications system anchor base station of claim 1 , wherein the circuitry is further configured to transmit neighboring cell list information indicating neighboring cells.

10. The mobile telecommunications system anchor base station of claim 1 , wherein signaling is communicated over the control plane and user data are communicated over the user plane, and wherein the circuitry is further configured to transmit system information over the control plane and the user plane.

11. A user equipment being connected to at least one anchor cell and at least one slave cell of a mobile telecommunications system, the mobile telecommunications system comprising the anchor cell being a control plane cell and being configured to communicate with at least one user equipment and at least one slave cell being a user plane cell, the at least one slave cell being established by a slave base station and being configured to communication with the at least one user equipment and an anchor base station, the user equipment comprising a circuitry being configured to:

obtain geolocation information of the user equipment for determining whether a specific beam of a plurality of possible beams is suitable for the user equipment being located at a location identified by the geolocation information;

transmit the geolocation information to the anchor base station;

when the user equipment is in a radio resource control connected state receive system information from a specific beam from the anchor base station, based on the geolocation information, wherein the specific beam is provided from the anchor base station; and

receive user plane cell specific system information or control plane cell specific information, including scheduling information indicating a broadcast schedule for the specific beam.

12. The user equipment of claim 11 , wherein the circuitry is further configured to receive the system information including beam information about the specific beam.

13. The user equipment of claim 12 , wherein the beam information further includes coverage information of the specific beam.

14. The user equipment of claim 12 , wherein the beam information further includes line of sight information.

15. The user equipment of claim 12 , wherein the circuitry is further configured to receive updated system information based on the beam information.

16. The user equipment of claim 12 , wherein the circuitry is further configured to receive the system information from a specific anchor cell or slave cell, based on the beam information.

17. The user equipment of claim 11 , wherein the specific beam is an anchor cell beam or slave cell beam.
