Sidelink feedback reporting in a wireless network
A wireless device may receive, from a base station, first configuration parameters and second configuration parameters. The first configuration parameters may indicate first physical layer uplink control channel (PUCCH) resources for reporting uplink feedback to the base station, and the second configuration parameters may indicate second PUCCH resources for reporting sidelink feedback to the base station. The wireless device may transmit, via a first PUCCH resource of the first PUCCH resources, an uplink feedback report of a downlink transport block. The wireless device may transmit, via a second PUCCH resource of the second PUCCH resources, a sidelink feedback report of a sidelink transport block.
