TIMING ADVANCE VALIDATION

Abstract:

There is described a terminal device for use in a wireless telecommunication system, wherein the terminal device comprises controller circuitry and transceiver circuitry configured to operate together such that the terminal device is operable to: determine a current timing advance for transmitting data to another entity in the wireless telecommunication system; determine an indication of a distance between the terminal device and the other entity; determine a timing advance validity threshold based on the indication of the distance between the terminal device and the other entity; determine an indication of a change in the distance between the terminal device and the other entity; and determine whether or not the current timing advance should be updated based on a comparison between the indication of the change in the distance between the terminal device and the other entity and the timing advance validity threshold.
