Abstract

In one embodiment, a mobile communication system is provided comprising a base station, a relay station, and a mobile station, a determiner configured to determine the distance between the mobile station and the base station or between the mobile station and the relay station, a decider configured to decide whether data transmission between the base station and the mobile station is carried out in a first relaying mode or a second relaying mode based on the determined distance and a controller configured to control the mobile communication system based on the result of the decision by the decider.

Claims

1. A mobile communication system comprising:

a plurality of base stations, a relay station associated with the plurality of base stations, and a plurality of mobile stations associated with the plurality of base stations, wherein, in a first relaying mode, each base station is configured to transmit data to be forwarded to at least one associated mobile station of the plurality of mobile stations to the relay station using first communication resources, wherein the first communication resources for all base stations of the plurality of base stations are identical and wherein, in the first relaying mode, the relay node is to transmit data to the plurality of mobile stations using second communication resources, wherein the second communication resources for all mobile stations of the plurality of mobile stations are identical;

a determiner to determine, for each mobile station, the distance between the mobile station and at least one of the base stations or between the mobile station and the relay station;

a decider to decide, for each mobile station, whether data transmission between the at least one base station and the mobile station is carried out in the first relaying mode or in a second relaying mode based on the determined distance; and

a controller to control the mobile communication system based on the result of the decision by the decider.

2. The mobile communication system according to claim 1, wherein the first relaying mode is that data transmission between the at least one base station and the mobile station is carried out via the relay station.

3. The mobile communication system according to claim 1, wherein the second relaying mode is that data transmission between the at least one base station and the mobile station is carried out without the relay station.

4. The mobile communication system according to claim 1, wherein the second relaying mode is that data transmission between the at least one base station and the mobile station is carried out without any relay station.

5. The mobile communication system according to claim 1, wherein the determiner, the decider, and the controller are part of the at least one base station, the relay station, the mobile station or a network component of the mobile communication system.

6. The mobile communication system according to claim 1, wherein the decider is to decide that the data transmission between the at least one base station and the mobile station is carried out in the first relaying mode if the distance between the mobile station and the at least one base station is above a first pre-determined threshold or if the distance between the mobile station and the relay station is below a second pre-determined threshold.

7. The mobile communication system according to claim 1, wherein the decider is to decide that the data transmission between the at least one base station and the mobile station is carried out in the second relaying mode if the distance between the mobile station and the at least one base station is below a first pre-determined threshold or if the distance between the mobile station and the relay station is above a second pre-determined threshold.

8. The mobile communication system according to claim 1, wherein the mobile communication system has a (m,n)-relaying architecture with m higher than 1.

9. A method for data transmission in a mobile communication system comprising a plurality of base stations, a plurality of relay stations, and a plurality of mobile stations, wherein, in a first relaying mode, each base station is to transmit data to be forwarded to at least one mobile station of the plurality of mobile stations to the relay node using first communication resources, wherein the first communication resources for all base stations of the plurality of base stations are identical and wherein, in the first relaying mode, the relay node is to transmit data to the plurality of mobile stations using second communication resources, wherein the second communication resources for all mobile stations of the plurality of mobile stations are identical;

the method comprising determining, for each mobile station, a distance between the mobile station and at least one of the base stations or between the mobile station and the relay station;

deciding, for each mobile station, whether data transmission between the at least one base station and the mobile station is carried out in the first relaying mode or in a second relaying mode based on the determined distance; and

carrying out, for each mobile station, data transmission between the at least one base station and the mobile station based on the result of the decision by the decider.
