CLOSED LOOP TIME AND FREQUENCY CORRECTIONS IN NON-TERRESTRIAL NETWORKS - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17733636 Titled 'CLOSED LOOP TIME AND FREQUENCY CORRECTIONS IN NON-TERRESTRIAL NETWORKS'
Simplified Explanation
This abstract describes methods, systems, and devices for wireless communications. It explains techniques for reducing errors in time or frequency adjustments for preambles of a random access procedure. In this process, a user equipment (UE) may use a specific adjustment value when transmitting data to a non-terrestrial network. However, when transmitting the preamble of a random access procedure, the UE adjusts the timing or frequency based on indications received from the network, rather than resetting the adjustment to zero. This approach helps maintain or improve the reception performance of the preamble, requiring fewer position measurements for the UE or non-terrestrial network entity.
Original Abstract Submitted
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.
