1. A wireless user device comprising:
one or more antennas;
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the wireless user device to:
receive, from a base station, sidelink downlink control information (SL DCI) associated with transmission of one or more sidelink signals;
based on the SL DCI, transmit, to one or more second wireless user devices, the one or more sidelink signals via a first quantity of sidelink channel resources;
during a first time interval, receive, from the one or more second wireless user devices, first sidelink HARQ feedback information responsive to the one or more sidelink signals, wherein a second time interval is identified, based on a first sidelink HARQ feedback timing and based on the first time interval, for transmitting the first sidelink HARQ feedback information;
receive, from the base station, second SL DCI associated with transmission of one or more second sidelink signals, wherein the second SL DCI comprises an indicator field that indicates a second sidelink HARQ feedback timing;
based on the second SL DCI, transmit one or more second sidelink signals via a second quantity of second sidelink channel resources;
during a third time interval, receive second sidelink HARQ feedback information responsive to the one or more second sidelink signals, wherein the second time interval is identified, based on the second sidelink HARQ feedback timing and based on the third time interval, for transmitting the second sidelink HARQ feedback information; and
during the second time interval and based on a sidelink HARQ codebook, transmit, to the base station, an uplink signal indicating:
the first sidelink HARQ feedback information; and
the second sidelink HARQ feedback information,
wherein the sidelink HARQ codebook is based on the first quantity and the second quantity.
