Abstract

The present disclosure relates to base station and method for content synchronization when broadcasting data in a communications network. The base station comprises a receiver configured to receive data sequences and a transmitter configured to transmit content of the received data sequence. Each data sequence comprises a packet level sequence number and byte-numbered sequence numbers. The base station further comprises a processing circuitry configured to synchronize transmission with another base station of the content using said packet level sequence number and said byte-numbered sequence numbers.

First claim

The invention claimed is:

1. A base station configured to synchronize content when broadcasting data in a communications network, the base station comprising:
a receiver configured to receive data sequences (PDUs);
wherein each received data sequence comprises a packet level sequence number and byte-numbered sequence numbers;
the base station further comprising:
a transmitter configured to transmit content of the received data sequence; and
processing circuitry configured to synchronize transmission with another base station of the content using said packet level sequence number and said byte-numbered sequence numbers.

2. The base station of claim 1 , wherein the same content is sent from the base station and the another base station in a same radio resource block.

3. The base station of claim 1 , wherein said processing circuitry is configured to determine which PDU or which part of a PDU should be used to resume transmission.

4. The base station of claim 1 , wherein said processing circuitry is configured to use a sequence number of a subsequent received PDU and a sequence number of a last received PDU to determine a lost number of bytes of data and determine a transmission continuation with a subsequent PDU.

5. The base station of claim 1 , wherein the packet level sequence number and byte-numbered sequence numbers are provided by a SYNC protocol.

6. The base station of claim 1 , further comprising a buffer configured to receive data sequences comprising a packet header and no user data part, said packet header comprising a byte-level sequence number, which is set according to a virtual data associated with said data sequence.

7. A method of a base station for content synchronization when broadcasting data in a communications network, the method comprising:
receiving data sequences (PDUs);
wherein each received data sequence comprises a packet level sequence number and byte-numbered sequence numbers; and
transmitting content of the received data sequences in synchronization with another base station using said packet level sequence number and byte-numbered sequence numbers.

8. The method of claim 7 , further comprising mapping said content to a corresponding radio resource block by relying on the packet level sequence number and byte-numbered sequence numbers.

9. The method of claim 7 , wherein the packet level sequence number and byte-numbered sequence numbers are provided by a SYNC protocol.

10. An arrangement for content synchronization when transmitting data from an infrastructure node in a communications network, said arrangement comprising:
processing circuitry configured to add a packet level sequence number and byte-numbered sequence numbers to a data sequence for transmission to a base station; and
a transmitter configured to transmit the data sequences with the packet level sequence number and byte-numbered sequence numbers and content to a plurality of base stations, wherein said packet level sequence number and byte-numbered sequence numbers enable content synchronization by the base stations.

11. The arrangement of claim 10 , wherein the packet level sequence number and byte-numbered sequence numbers are provided by a SYNC protocol.

12. The arrangement of claim 10 , wherein the arrangement is configured to obtain the sequence number of a subsequent packet by incrementing a sequence number of a previous packet by a size of the previous packet.

13. A method of content synchronization when broadcasting data in a communications network, the method comprising:
adding a packet level sequence number and byte-numbered sequence numbers to content for transmission in a data sequence to a base station; and
transmitting the data sequences with the packet level sequence number and byte-numbered sequence numbers to a plurality of base stations;
wherein said packet level sequence number and byte-numbered sequence numbers enable content synchronization by the base stations.

14. The method of claim 13 , further comprising mapping said content to a corresponding radio resource block by relying on the byte-numbered sequence numbers.

15. The method of claim 13 , further comprising:
determining if a data sequence is lost and which data sequence or which part of said data sequence should be resumed upon transmission; and
using a sequence number of a subsequent received data sequence and a sequence number of a last received data sequence to determine the lost number of bytes of data and determine transmission continuation with subsequent data sequence.

16. The method of claim 13 , wherein the packet level sequence number and byte-numbered sequence numbers are provided by a SYNC protocol.
