Abstract

A mobile telecommunications system anchor entity for a mobile telecommunications system is provided. The mobile telecommunications system has at least one entity serving at least one user equipment, wherein the at least one entity and the at least one user equipment are located in a common system information area. The mobile telecommunications system has circuitry, which performs transmitting minimum system information to the at least one user equipment, wherein the minimum system information includes system information area identifier information.

First claim

1 . A mobile telecommunications system anchor entity for a mobile telecommunications system including at least one entity serving at least one user equipment, wherein the at least one entity and the at least one user equipment are located in a common system information area, comprising circuitry configured to:
transmit minimum system information to the at least one user equipment, wherein the minimum system information includes system information area identifier information.

2 . The mobile telecommunications system anchor entity of claim 1 , wherein the minimum system information includes information about entities within the system information area.

3 . The mobile telecommunications system anchor entity of claim 1 , wherein the circuitry is further configured to transmit information about entities within the system information area on demand to the at least one user equipment.

4 . The mobile telecommunications system anchor entity of claim 3 , wherein the information about entities is transmitted based on at least one of moving speed and moving direction of the user equipment.

5 . The mobile telecommunications system anchor entity of claim 1 , wherein each entity in the system information area transmits the minimum system information.

6 . The mobile telecommunications system anchor entity of claim 1 , wherein the minimum system information is transmitted upon detection of at least one of an uplink reference signal or measurement report from the user equipment.

7 . The mobile telecommunications system anchor entity of claim 6 , wherein the user equipment is in at least one of the following states: idle, connected and inactive connected.

8 . The mobile telecommunications system anchor entity of claim 1 , wherein the circuitry is configured to transmit the system information area identifier information.

9 . The mobile telecommunications system anchor entity of claim 8 , wherein the circuitry is further configured to transmit system information of other entities located within the system information area.

10 . The mobile telecommunications system anchor entity of claim 8 , wherein the circuitry is further configured to transmit system information which is common with other entities of the system information area.

11 . The mobile telecommunications system anchor entity of claim 10 , wherein the common system information includes common service system information.

12 . The mobile telecommunications system anchor entity of claim 10 , wherein the common system information includes common resource related information.

13 . The mobile telecommunications system anchor entity of claim 8 , wherein another anchor entity is located within the system information area and wherein the circuitry is further configured to perform the transmission of the minimum system information based on at least one of: a single frequency network for the at least two anchor entities or different broadcast channels for the at least two anchor entities.

14 . The mobile telecommunications system anchor entity of claim 13 , wherein the anchor entity is a first mobile telecommunications system entity and the other anchor entity is a second mobile telecommunications system entity, and wherein the transmitted minimum system information includes system information for the first mobile telecommunications system and for the second mobile telecommunications system.

15 - 17 . (canceled)

18 . The mobile telecommunications system anchor entity of claim 1 , wherein the system information area configuration can be changed dynamically.

19 - 21 . (canceled)

22 . A mobile telecommunications system entity for a mobile telecommunications system including at least one anchor cell entity serving at least one user equipment, wherein the at least one entity and the at least one user equipment are located in a common system information area and wherein the at least one anchor cell entity transmits minimum system information to the at least one user equipment, comprising circuitry configured to:
transmit at least one of other system information and scheduling information to the at least one user equipment.

23 - 30 . (canceled)

31 . A user equipment for a mobile telecommunications system including at least one entity serving the user equipment, wherein the at least one entity and the user equipment are located in a common system information area, the user equipment comprising circuitry configured to:
receive minimum system information including system information area identifier information; and determine, based on the received system information area identifier information, whether a new system information area is entered.

32 . The user equipment claim 17 , wherein the circuitry is further configured to receive information about entities within the system information area.

33 . The user equipment of claim 18 , wherein the circuitry is further configured to request the information about entities within the system information area.

34 . The user equipment of claim 19 , wherein the circuitry is further configured to transmit at least one of an uplink reference signal and a measurement report.
