Abstract
Methods, systems, and devices for wireless communications are described. Described techniques provide for mitigating error in time or frequency adjustments for preambles of a random access procedure. A user equipment may use one value for the adjustment when transmitting data to a non-terrestrial network, but then transmit the preamble of a random access procedure according to a preamble-specific time or frequency adjustment based on one or more indications received from the network (e.g., rather than resetting the adjustment to '0'). By using some signaled value for the preamble-specific timing or frequency adjustment rather than resetting the adjustment to “0,” preamble reception performance may be maintained or improved with as many or fewer position measurements for the UE or non-terrestrial network entity.
