Abstract
A method performed by a wireless device (110) includes determining that the wireless device has data to transmit in the sidelink, SL, buffer. A special scheduling request, SR, is transmitted using a SR resource to the network node to indicate that a SL resource allocation, SL RA, is needed. A grant is received from the network node for transmitting at least the data in the SL buffer. Based on the grant, at least the data in the SL buffer is transmitted.
Claims29
A method performed by a wireless device, the method comprising:
- determining that the wireless device has data to transmit in at least a sidelink, SL, buffer;
- transmitting, using a scheduling request, SR, resource, a special scheduling request to a network node to indicate that a SL resource allocation, SL RA, is needed;
- receiving, from the network node, a grant for transmitting at least the data in the SL buffer;
- and
- based on the grant, transmitting at least the data in the SL buffer.
-10. (canceled)
A method performed by a base station, the method comprising:
- receiving, from a wireless device, a special scheduling request, SR, associated with a SR resource;
- based on the SR resource, determining that the wireless device has data to transmit on either a sidelink, SL, or the SL and an uplink, UL;
- transmitting, to the wireless device (110), a grant sufficient for transmitting the data on the SL or the SL and the UL.
-32. (cancaled)
A wireless device comprising:
- processing circuitry configured to:
- determine that the wireless device has data to transmit in at least a sidelink, SL, buffer;
- transmit, using a scheduling request, SR, resource, a special scheduling request to a network node to indicate that a SL resource allocation, SL RA, is needed;
- receive, from the network node, a grant for transmitting at least the data in the SL buffer;
- and
- based on the grant, transmit at least the data in the SL buffer.
A base station comprising:
- processing circuitry configured to:
- receive, from a wireless device, a special scheduling request (SR) associated with a SR resource;
- based on the SR resource, determine that the wireless device has data to transmit on either a sidelink, SL, or the SL and an uplink, UL;
- transmit, to the wireless device, a grant sufficient for transmitting the data on the SL or the SL and the UL.
