Abstract

Communication devices are provided that facilitate receiving information units and providing feedback to other communication devices.

First claim

The invention claimed is:

1. A communication device comprising:
a processor circuit and a memory circuit, wherein the memory is arranged to store instructions for the processor circuit,
wherein the processor circuit is arranged to receive at least one information units from a plurality of second communication devices,
wherein the processor circuit is arranged to receive at least one resource allocation message from a third communication device,
wherein the at least one resource allocation message defines an allocation of bit positions associated with an acknowledgement of the at least one information units in a combined acknowledgement information unit,
wherein the processor circuit is arranged to transmit a combined acknowledgement information unit in response to a reception of the at least one information units using the allocation of bit positions defined in the at least one resource allocation message.

2. The communication device according to claim 1 , wherein the processor circuit is arranged to broadcast or multicast the combined acknowledgement information unit.

3. The communication device according to claim 2 , wherein the processor circuit is arranged to broadcast the combined acknowledgement information unit to the plurality of second communication devices via a side link.

4. The communication device according to claim 3 , wherein the sidelink which does not use a base station.

5. The communication device according to claim 1 ,
wherein the processor circuit is arranged to set bits at bit positions associated with at least one of the plurality of second communication devices from which at least one information units were properly received to a first bit value,
wherein the processor circuit is arranged to set bits at bit positions associated with at least one of the plurality of second communication devices from which at least one information units were not properly received.

6. The communication device according to claim 1 , wherein the processor circuit is arranged to transmit a combined acknowledgement information unit for the at least one information units received from fourth communication devices within a predetermined period of time.

7. The communication device according to claim 1 ,
wherein the at least one resource allocation message defines in which wireless resource unit the combined acknowledgement information unit is transmitted,
wherein the processor circuit is arranged to transmit the combined acknowledgement information unit in the wireless resource unit specified by the at least one resource allocation message.

8. The communication device according to claim 1 ,
wherein the processor circuit is arranged to evaluate at least one resource allocation message,
wherein the resource allocation message is piggybacked on a data.

9. The communication device according to claim 1 ,
wherein the processor circuit is arranged to set bits at bit positions associated with at least one of the plurality of second communication devices from which at least one information units were properly received to a first bit value,
wherein the processor circuit is arranged to set bits at bit positions associated with at least one of the plurality of second communication devices from which at least one information units were not received to a second bit value which is different from the first bit value.

10. A communication device comprising:
a processor circuit and a memory circuit, wherein the memory is arranged to store instructions for the processor circuit,
wherein the processor circuit is arranged to transmit at least one information units to fifth communication device,
wherein the processor circuit is arranged to receive at least one resource allocation message from a third communication device,
wherein the at least one resource allocation message defines an allocation of bit positions associated with an acknowledgement of the at least one information units in a combined acknowledgement information unit, and wherein the processor circuit is arranged to receive a combined acknowledgement information unit,
wherein the processor circuit is arranged to evaluate a bit at a bit position defined by the at least one resource allocation message so as to derive an information whether at least one information units have been received by the fifth communication device.

11. The communication device according to claim 10 , wherein the processor circuit is arranged to retransmit an information unit to the fifth communication device when the evaluated bit of the combined acknowledgement information unit indicates that a previous transmission of the information unit has not been received by the fifth communication device.

12. The communication device according to claim 10 ,
wherein the at least one resource allocation message defines in which wireless resource unit the combined acknowledgement information unit is transmitted,
wherein the processor circuit is arranged to receive the combined acknowledgement information unit in the wireless resource unit specified by the at least one resource allocation message.

13. The communication device according to claim 12 ,
wherein the processor circuit is arranged to evaluate at least one resource allocation message,
wherein the resource allocation message is piggybacked on a data.

14. A communication device comprising:
a processor circuit and a memory circuit, wherein the memory is arranged to store instructions for the processor circuit,
wherein the processor circuit is arranged to coordinate at least one resource allocation to a plurality of second communication devices,
wherein the processor circuit is arranged to communicate with the plurality of second communication devices,
wherein the processor circuit is arranged to provide at least one resource allocation information to the plurality of second communication devices,
wherein the at least one resource allocation information defines an allocation of bit positions associated with an acknowledgement of the at least one information units received by a first communication device from a plurality of second communication devices in a combined acknowledgement information unit,
wherein the processor circuit is arranged to transmit the combined acknowledgement information unit in response to a reception of the at least one information units from a plurality of the second communication devices.

15. The communication device according to claim 14 ,
wherein the processor circuit is arranged to provide at least one resource allocation information,
wherein the resource allocation information defines an allocation of wireless resource units for transmissions from a portion of the plurality of second communication devices to the first communication device via a side link which does not involve the communication device itself.

16. The communication device according to claim 15 , wherein side link does not use the communication device.

17. The communication device according to claim 14 ,
wherein the processor circuit is arranged identify a sixth communication device,
wherein a plurality of second communication devices send the at least one information units on the basis of an allocation of wireless resource to the sixth communication device,
wherein the processor circuit is arranged to reserve a wireless resource unit,
wherein the first communication device transmits the combined acknowledgement information unit in response to the identification of the sixth communication device,
wherein the sixth communication device is arranged to allocate the bit positions within the
