## Abstract

A base station for a mobile telecommunications system has circuitry configured to communicate with at least one user equipment. The circuitry is further configured to transmit minimum system information having a bitmap indicating at least one service provided by a cell.

## Claims

### Claim 1

A base station for a mobile telecommunications system comprising circuitry configured to communicate with at least one user equipment, wherein the circuitry is further configured to:
transmit minimum system information including a bitmap indicating at least one service provided by a cell.

### Claim 2 (depends on 1)

The base station of claim 1, wherein the bitmap includes multiples bits, wherein each bit indicates an associated service, which is provided by the cell.

### Claim 3 (depends on 1)

The base station of claim 1, wherein the bitmap includes multiple bits, wherein each bit indicates an associated group of services provided by the cell.

### Claim at position 4

-6. (canceled)

### Claim 7

A base station for a mobile telecommunications system comprising circuitry configured to communicate with at least one user equipment, wherein the circuitry is further configured to:
transmit scheduling information, the scheduling information being indicative of at least one service provided by a cell.

### Claim 8 (depends on 7)

The base station of claim 7, wherein the scheduling information includes scheduling information for a system information block, the system information block including service related information for the at least one service provided by the cell.

### Claim at position 7

-10. (canceled)

### Claim 11

A base station for a mobile telecommunications system comprising circuitry configured to communicate with at least one user equipment, wherein the circuitry is further configured to:
transmit information in a master information block indicating that a cell is a service dedicated cell.

### Claim 12 (depends on 11)

The base station of claim 11, wherein the information includes one bit for indicating that the cell is a service dedicated cell.

### Claim 13 (depends on 11)

The base station of claim 11, wherein the circuitry is further configured to transmit system information including a bitmap indicating at least one service provided by the service dedicated cell.

### Claim 14 (depends on 13)

The base station of claim 13, wherein the bitmap is included in a system information block which is associated with the service dedicated cell.

### Claim 15 (depends on 14)

The base station of claim 14, wherein the bitmap is included in scheduling information.

### Claim at position 13

-33. (canceled)
