## Abstract

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

## Claims

### Claim 1

A device comprising:
a processor circuit; and
a memory circuit, wherein the memory circuit is arranged to store instructions for the processor circuit,
wherein the processor circuit is arranged to receive at least one first information from a plurality of second devices,
wherein the processor circuit is arranged to receive a resource allocation message from a managing device,
wherein the resource allocation message defines an allocation of bit positions,
wherein the bit positions are associated with an acknowledgement of the at least one first information,
wherein the processor circuit is arranged to transmit an acknowledgement information in response to a reception of the at least one first information from the plurality of second devices.

### Claim 2 (depends on 1)

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

### Claim 3 (depends on 2)

The communication device according to claim 2,
wherein the processor circuit is arranged to broadcast the acknowledgement information to the plurality of second devices via a side link,
wherein the side link does not use a base station.

### Claim 4 (depends on 1)

The communication device according to claim 1,
wherein the processor circuit is arranged to set bits at bit positions to a first value when the bit positions are associated with at least one of the plurality of second devices from which at least one first information is properly received,
wherein the processor circuit is arranged to set bits at bit positions to a second bit value when the bit positions are associated with at least one the plurality of second devices from which at least one first information were not properly received or from which none of the first information is received.

### Claim 5 (depends on 1)

The communication device according to claim 1, wherein the processor circuit is arranged to transmit an acknowledgement information for the at least one first information received from a third devices within a predetermined period of time.

### Claim 6 (depends on 1)

The communication device according to claim 1, wherein the processor circuit is arranged to transmit the acknowledgement information in the resource specified by the resource allocation message.

### Claim 7 (depends on 1)

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

### Claim 8

A method comprising:
receiving at least one first information from a plurality of second devices,
receiving a resource allocation message from a managing device,
wherein the resource allocation message defines an allocation of bit positions,
wherein the bit positions are associated with an acknowledgement of the at least one first information,
transmitting an acknowledgement information in response to a reception of the at least one first information from the plurality of second devices.

### Claim 9 (depends on 8)

A computer program stored on a non-transitory medium, wherein the computer program when executed on a processor performs the method as claimed in claim 8.

### Claim 10

A communication device comprising:
a processor circuit; and
a memory circuit, wherein the memory circuit is arranged to store instructions for the processor circuit,
wherein the processor circuit is arranged to receive at least one first information from a plurality of second devices,
wherein the processor circuit is arranged to receive a resource allocation message from a managing device,
wherein the resource allocation message defines an allocation of bit positions,
wherein the bit positions are associated with an acknowledgement of the least one first information,
wherein the processor circuit is arranged to transmit a acknowledgement information in response to a reception of at least one first information from the plurality of second devices,
wherein the transmission of the acknowledgment information signals whether the communication device has properly received the at least one first information from the plurality of second devices or not.

### Claim 11 (depends on 10)

The communication device according to claim 10,
wherein the processor circuit is arranged to set bits at bit positions to a first value when the bit positions are associated with at least one of the plurality of second devices from which at least one first information were properly received,
wherein the processor circuit is arranged to set bits at bit positions to a second bit value when the bit positions are associated with at least one of the plurality of second devices from which at least one first information were not properly received or from which none of the least one first information were,
wherein the setting of the bits provides feedback information to the plurality of second devices.
