Abstract

A terminal device in a wireless telecommunication system which transmits a master information block and a first and a second system information block the first and second system information block comprising first and second scheduling information relating to the timing of at least one additional block of system information. The terminal device configured to receive the master information block of system information that comprises a marker instructing the terminal device to ignore the first scheduling information and process only the second scheduling information.

Claims

1. A terminal device comprising:

circuitry configured to;

receive a master information block (MIB) from a base station of a wireless telecommunication system, wherein

the base station is configured to transmit the MIB, a first system information block (SIB), and a second (SIB),

the first SIB includes first scheduling information, the second SIB includes second scheduling information, and the first scheduling information and the second scheduling information relate to a timing of at least one additional block of system information, and

the MIB includes an information element indicating that the second SIB is being transmitted from the base station;

decode the MIB;

determine whether the information element included in the MIB indicates that the second SIB is being transmitted from the base station; and

ignore the first SIB and process the second SIB when it is determined that the information element indicates that the second SIB is being transmitted from the base station, wherein the second scheduling information included in the second SIB indicates a time domain window for receiving at least one additional block of system information.

2. The terminal device of claim 1, wherein

the information element is a one bit flag indicating whether the second SIB is being transmitted from the base station.

3. The terminal device of claim 1, wherein

the MIB includes timing information relating to a transmission timing of the first SIB.

4. The terminal device of claim 1, wherein

the MIB includes timing information relating to a transmission timing of the second SIB.

5. The terminal device of claim 1, wherein

the first SIB is a SystemInformationBlockType1.

6. The terminal device of claim 1, wherein

the first SIB is transmitted at a fixed scheduled having a periodicity of 80 ms.

7. The terminal device of claim 1, wherein

the second SIB is a SIB for reduced-capability terminal devices that are configured to operate in a limited bandwidth.

8. The terminal device of claim 1, wherein

the terminal device is a reduced-capability wireless terminal device configured to operate in a limited bandwidth.

9. The terminal device of claim 1, wherein

the MIB, the first SIB, and the second SIB are transmitted in a physical downlink shared channel (PDSCH).

10. A method of operating a terminal device in a wireless telecommunication system, the method comprising:

receiving, by the terminal device, a master information block (MIB) from a base station of the wireless telecommunication system, wherein

the base station is configured to transmit the MIB, first system information block (SIB), and a second SIB,

the first SIB includes first scheduling information, the second SIB includes second scheduling information, and the first scheduling information and the second scheduling information relate to a timing of at least one additional block of system information, and

the MIB includes an information element indicating that the second SIB is being transmitted from the base station;

decoding the MIB;

determining whether the information element included in the MIB indicates that the second SIB is being transmitted from the base station;

ignoring the first SIB and processing the second SIB when it is determined that the information element indicates that the second SIB is being transmitted from the base station, wherein the second scheduling information included in the second SIB indicates a time domain window for receiving at least one additional block of system information.

11. The method of claim 10, wherein

the information element is a one bit flag indicating whether the second SIB is being transmitted from the base station.

12. The method of claim 10, wherein

the MIB includes timing information relating to a transmission timing of the first SIB.

13. The method of claim 10, wherein

the MIB includes timing information relating to a transmission timing of the second SIB.

14. The method of claim 10, wherein

the first SIB is a SystemInformationBlockType1.

15. The method of claim 10, wherein

the first SIB is transmitted at a fixed scheduled having a periodicity of 80 ms.

16. The method of claim 10, wherein

the second SIB is a SIB for reduced-capability terminal devices that are configured to operate in a limited bandwidth.

17. The method of claim 10, wherein

the terminal device is a reduced-capability wireless terminal device configured to operate in a limited bandwidth.

18. A non-transitory computer-readable medium storing instructions that, when executed by one or more processors of a terminal device, cause the terminal device to:

receive a master information block MIB from a base station of a wireless telecommunication system, wherein

the base station is configured to transmit the MIB, a first system information block (SIB), and a second SIB,

the first SIB includes first scheduling information, the second SIB includes second scheduling information, and the first scheduling information and the second scheduling information relate to a timing of at least one additional block of system information, and

the MIB includes an information element indicating that the second SIB is being transmitted from the base station;

decode the MIB;

determine whether the information element included in the MIB indicates that the second SIB is being transmitted from the base station;

ignore the first SIB and processing the second SIB when it is determined that the information element indicates that the second SIB is being transmitted from the base station, wherein the second scheduling information included in the second SIB indicates a time domain window for receiving at least one additional block of system information.
