## Abstract

A base station may transmit, to a first wireless device, a timing offset indicator indicating an offset, in slots, between a sidelink feedback resource and an uplink feedback resource. The base station may receive, from the first wireless device and in an uplink slot, a sidelink feedback report. A first sidelink feedback resource within a sidelink slot may be at a time indicated by the offset from a second sidelink feedback resource for a sidelink transport block transmitted by the first wireless device to a second wireless device. The uplink slot may overlap with the first sidelink feedback resource in time, and the uplink slot may be a last uplink feedback slot overlapping with the first sidelink feedback resource.

## Claims

### Claim 1

A method comprising:
transmitting, by a base station to a first wireless device, a timing offset indicator indicating an offset, in a number of slots, between a sidelink feedback resource and an uplink feedback resource for transmitting a sidelink feedback report; and
receiving, by the base station from the first wireless device, the sidelink feedback report in an uplink slot, wherein:
the uplink slot is a last uplink feedback slot overlapping with a first sidelink feedback resource, within a sidelink slot, in time;
the first sidelink feedback resource is offset from a second sidelink feedback resource by the number of slots; and
the second sidelink feedback resource is a feedback resource for a sidelink transport block transmitted by the first wireless device to a second wireless device.

### Claim 2 (depends on 1)

The method of claim 1, wherein the timing offset indicator is transmitted via a downlink control information (DCI).

### Claim 3 (depends on 2)

The method of claim 2, wherein the DCI comprises a field for the timing offset indicator.

### Claim 4 (depends on 1)

The method of claim 1, wherein the timing offset indicator is transmitted via radio resource control (RRC) message.

### Claim 5 (depends on 1)

The method of claim 1, wherein the transmitting further comprises transmitting, by the base station to the first wireless device, an indication of one or more sidelink transmission resources for the first wireless device to transmit the sidelink transport block to the second wireless device.

### Claim 6 (depends on 1)

The method of claim 1, wherein the uplink feedback resource of the uplink slot comprises a physical uplink control channel (PUCCH).

### Claim 7 (depends on 1)

The method of claim 1, wherein the first sidelink feedback resource comprises a physical sidelink feedback channel (PSFCH).

### Claim 8 (depends on 1)

The method of claim 1, wherein the first wireless device operates under resource allocation mode 1 in which the base station schedules sidelink transmissions.

### Claim 9 (depends on 1)

The method of claim 1, wherein the sidelink feedback report comprises at least one of:
a hybrid automatic repeat request (HARQ) acknowledgement (ACK); or
a HARQ non-acknowledgment (NACK).

### Claim 10 (depends on 1)

The method of claim 1, wherein the offset, indicated by the timing offset indicator, is between a first time when the first wireless device receives a sidelink feedback from the second wireless device and a second time when the first wireless device transmits the sidelink feedback report to the base station.

### Claim 11

A base station comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the base station to:
transmit, to a first wireless device, a timing offset indicator indicating an offset, in a number of slots, between a sidelink feedback resource and an uplink feedback resource for transmitting a sidelink feedback report; and
receive, from the first wireless device, the sidelink feedback report in an uplink slot, wherein:
