Abstract

A D2D device for a wireless communication network is described. The D2D device comprises a set of transmitters and/or a set of receivers. Furthermore, the D2D device is adapted for determining one or more transmitters from the set of 5 transmitters and/or one or more receivers from the set of receivers, which are to be used for at least one D2D operation. There are also described related methods and devices.

Claims

1. A method for operating a device-to-device (D2D) device for a wireless communication network, the D2D device comprising a set of transmitters and/or a set of receivers, the set of transmitters and/or set of receivers each comprising at least two that are capable of D2D operation according to a first radio access technology, the method comprising determining one or more transmitters from the set of transmitters and/or one or more receivers from the set of receivers to be used for at least one D2D operation.

2. The method of claim 1, wherein the determined one or more transmitters from the set of transmitters and/or one or more receivers from the set of receivers to be used for at least one D2D operation comprises a first transmitter and the at least one D2D operation comprises a data transmission, via the first transmitter, from the D2D device to a second D2D device.

3. The method of claim 1, wherein the determined one or more transmitters from the set of transmitters and/or one or more receivers from the set of receivers to be used for at least one D2D operation comprises a first receiver and the at least one D2D operation comprises a data reception, via the first receiver, at the D2D device from a second D2D device.

4. The method of claim 1, wherein the D2D device is configured to receive data from a network node in downlink (DL) radio spectrum and/or DL radio resources and to transmit data to the network node in uplink (UL) radio spectrum and/or UL radio resources, and wherein the D2D operation comprises transmitting data to and/or receiving data from a second D2D device in the UL radio spectrum and/or UL radio resources.

5. A device-to-device (D2D) device for a wireless communication network, the D2D device comprising a set of transmitters and/or a set of receivers, the set of transmitters and/or set of receivers each comprising at least two that are capable of D2D operation according to a first radio access technology, the D2D device further comprising a processor circuit configured to determine one or more transmitters from the set of transmitters and/or one or more receivers from the set of receivers to be used for at least one D2D operation.

6. The D2D device of claim 5, wherein the determined one or more transmitters from the set of transmitters and/or one or more receivers from the set of receivers to be used for at least one D2D operation comprises a first transmitter and the at least one D2D operation comprises a data transmission, via the first transmitter, from the D2D device to a second D2D device.

7. The D2D device of claim 5, wherein the determined one or more transmitters from the set of transmitters and/or one or more receivers from the set of receivers to be used for at least one D2D operation comprises a first receiver and the at least one D2D operation comprises a data reception, via the first receiver, at the D2D device from a second D2D device.

8. The D2D device of claim 5, wherein the D2D device is configured to receive data from a network node in downlink (DL) radio spectrum and/or DL radio resources and to transmit data to the network node in uplink (UL) radio spectrum and/or UL radio resources, and wherein the D2D operation comprises transmitting data to and/or receiving data from a second D2D device in the UL radio spectrum and/or UL radio resources.

9. A method for operating a second device-to-device (D2D) device for a wireless communication network, the method comprising assisting a first D2D device in determining one or more transmitters from a set of transmitters and/or one or more receivers from a set of receivers, which are to be used by the first D2D device for at least one D2D operation.

10. A second device-to-device (D2D) device, for a wireless communication network, the second D2D device being configured to assist a first D2D device in determining one or more transmitters from a set of transmitters and/or one or more receivers from a set of receivers, which are to be used by the first D2D device for at least one D2D operation.

11. A method for operating a network node in a wireless communication network, the method comprising assisting a first device-to-device (D2D) device in determining one or more transmitters from a set of transmitters and/or one or more receivers from a set of receivers, which are to be used by the first D2D device for at least one D2D operation.

12. A network node for a wireless communication network, the network node being configured to assist a first device-to-device (D2D) device in determining one or more transmitters from a set of transmitters and/or one or more receivers from a set of receivers, which are to be used by the first D2D device for at least one D2D operation.
