Abstract

The invention relates to a mobile communication system. The mobile communication system includes a first base station configured to transmit at least part of a first data set of data segments arranged in a first sequence to a user terminal, and a second base station configured to transmit at least part of the first data set of data segments arranged in a second sequence to the user terminal, the second sequence of the first data set being an inverse of the first sequence of the first data set. The invention also relates to a coordination component, base station and user terminal for use in this system and to a method of arranging data segments in sequences performed by the coordination component. The invention further relates to a method of transmitting an acknowledgement, performed by the base station or by the user terminal.

First claim

What is claimed is:

1. A mobile communication system, comprising:
a first base station configured to transmit at least part of a first data set of data packets arranged in a first sequence to a user terminal;
a second base station configured to transmit at the same time at least part of said first data set of the same data packets arranged in a second sequence to said user terminal, said second sequence of said first data set being an inverse of said first sequence of said first data set; and
a third base station configured to transmit at the same time at least part of a second data set of data packets arranged in a first sequence to said user terminal, said second data set comprising different data packets than said first data set.

2. A mobile communication system as claimed in claim 1 , wherein, for each of said first base station and said second base station, said base station is configured to detect that a user terminal has not received a previous transmission by said base station of at least part of a data packet and to retransmit said at least a part of said data packet to said user terminal upon said detection.

3. A mobile communication system as claimed in claim 1 , wherein one of said first base station and said second base station is configured to transmit at least part of said second data set of data packets arranged in a second sequence after said user terminal has acknowledged receipt of said first data set, said first sequence of said second data set being an inverse of said second sequence of said second data set.

4. A mobile communication system as claimed in claim 3 , wherein the other one of said first base station and said second base station is configured to transmit at least part of a third data set of data packets after said user terminal has acknowledged receipt of said first data set, said third data set comprising different data packets than said first data set and said second data set.

5. A coordination component for use in a mobile communication system of claim 1 , comprising:
a data transmitter; and
a processor configured to arrange a first data set of data packets in a first sequence, to arrange said first data set of the same data packets in a second sequence, said second sequence of said first data set being an inverse of said first sequence of said first data set, and to use said data transmitter to transmit coordination information to at least one base station, said coordination information comprising at least one of a request to transmit said first data set in said first sequence to a user terminal and a request to transmit said first data set in said second sequence to said user terminal;
wherein said processor is further configured to arrange a second data set of data packets in a first sequence, said second data set comprising different data packets than said first data set, and to use said data transmitter to transmit further coordination information to a further base station, said further coordination information comprising one of a request to transmit said first data set in said first sequence to said user terminal, a request to transmit said first data set in said second sequence to said user terminal, and a request to transmit said second data set in said first sequence to said user terminal.

6. A coordination component as claimed in claim 5 , wherein said processor is further configured to arrange said second data set of data packets in a second sequence, said second sequence of said second data set being an inverse of said first sequence of said second data set, and said coordination information further comprises a request to transmit said second data set in said second sequence to said user terminal after said first data set has been transmitted.

7. A coordination component as claimed in claim 5 , wherein said processor is further configured to arrange a third data set of data packets in a first sequence and said coordination information further comprises a request to transmit said third data set in said first sequence to said user terminal after said first data set has been transmitted, said third data set comprising different data packets than said first data set and said second data set.

8. A user terminal for use in a mobile communication system of claim 1 , comprising:
a data receiver;
a data transmitter; and
a processor configured to use said data receiver to receive a first one of a plurality of data packets of a data set from a base station, to use said data transmitter to transmit a data packet acknowledgment acknowledging receipt of said first one of said plurality of data packets to said base station, to use said data receiver to receive a last one of said plurality of data packets of said data set from said base station, to use said data transmitter to transmit a data set acknowledgement acknowledging receipt of said data set to said base station and to a further base station and not to transmit said data packet acknowledgment to said further base station;
wherein said processor is further configured to use said data receiver to switch to receiving data packets from said further base station instead of said base station in dependence on at least one of reception conditions and load conditions with respect to said base station and said further base station.
