1. A wireless device, WD, configured to communicate with a network node, the WD comprising:

processing circuitry configured to:

obtain speed information about a speed of the WD, and bandwidth information about a bandwidth associated with a cell serving the WD, the speed information indicating that the WD is associated with one of a plurality of speed ranges, each of the plurality of speed ranges having an upper bound and corresponding to at least one transmit timing parameter;

adjust a transmit timing parameter of the WD based at least on the obtained information; and

transmit signals based at least on the adjusted transmit timing.
