Abstract: A method of operating a communications device for transmitting signals to and/or receiving signals from a non-terrestrial network (NTN) apparatus of a wireless communications network. The communications device acquires information for synchronising a transmission with the NTN apparatus. The communications device estimates a time remaining until an expiry time at which the information for synchronising the transmission with the apparatus will become invalid. The communications device receives, from the NTN apparatus, a biasing signal providing an indication to the communications device to bias an estimate of a time required to communicate the transmission with the NTN apparatus. The communications device determines, based at least in part on the indication provided by the biasing signal, the biased estimate of the time required to communicate the transmission with the NTN apparatus.
