Abstract

A wireless device receives a first message configuring one or more time intervals for transmissions of coordination information for one or more sidelink transmissions by a second wireless device. The coordination information indicates a set of resources for the one or more sidelink transmissions and/or a resource collision between a first resource and a second resource. A first sidelink control information (SCI) of the one or more sidelink transmissions includes a parameter indicating resource reservation of the first resource and the first wireless device receives a second SCI indicating resource reservation of the second resource. The wireless device selects, from the one or more time intervals, a time interval based on a discontinuous reception (DRX) active time of the second wireless device. The wireless device transmits, during the DRX active time and to the second wireless device and based on the time interval, the coordination information.
