Abstract
A wireless device may receive, from a base station, a timing offset indicator indicating an offset between a sidelink feedback resource and an uplink feedback resource. The wireless device may determine a second slot based on the timing offset indicator and a first slot for a sidelink feedback of a sidelink transport block transmitted by the wireless device. The wireless device may transmit, to the base station and via the uplink feedback resource in the second slot, a sidelink feedback report based on the sidelink feedback.
Claims16
A method comprising:
- receiving, by a first wireless device from a base station, a timing offset indicator indicating an offset, in slots, between a sidelink feedback resource and an uplink feedback resource;
- determining a first sidelink feedback resource within a sidelink slot by applying the offset to a second sidelink feedback resource for a sidelink transport block transmitted by the first wireless device to a second wireless device;
- determining an uplink slot that overlaps with the first sidelink feedback resource in time, wherein the uplink slot is a last uplink feedback slot overlapping with the first sidelink feedback resource;
- and
- transmitting, to the base station and in the uplink slot, a sidelink feedback report.
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- receive, from a base station, a timing offset indicator indicating an offset, in slots, between a sidelink feedback resource and an uplink feedback resource;
- determine a first sidelink feedback resource within a sidelink slot by applying the offset to a second sidelink feedback resource for a sidelink transport block transmitted by the first wireless device to a second wireless device;
- determine an uplink slot that overlaps with the first sidelink feedback resource in time, wherein the uplink slot is a last uplink feedback slot overlapping with the first sidelink feedback resource;
- and
- transmit, to the base station and in the uplink slot, a sidelink feedback report.
A system comprising:
- a base station comprising:
- one or more first processors and first memory storing first instructions that, when executed by the one or more first processors, cause the base station to:
- transmit a timing offset indicator indicating an offset, in slots, between a sidelink feedback resource and an uplink feedback resource;
- and
- a first wireless device comprising:
- one or more second processors and second memory storing second instructions that, when executed by the one or more second processors, cause the first wireless device to:
- receive, from the base station, the timing offset indicator indicating the offset, in slots, between the sidelink feedback resource and the uplink feedback resource;
- determine a first sidelink feedback resource within a sidelink slot by applying the offset to a second sidelink feedback resource for a sidelink transport block transmitted by the first wireless device to a second wireless device;
- determine an uplink slot that overlaps with the first sidelink feedback resource in time, wherein the uplink slot is a last uplink feedback slot overlapping with the first sidelink feedback resource;
- and
- transmit, to the base station and in the uplink slot, a sidelink feedback report.
