20250184929. Reference Signal Time Difference (r (Apple .)

REFERENCE SIGNAL TIME DIFFERENCE (RSTD) IN A NON-TERRESTRIAL WIRELESS NETWORK (NTN)

Abstract: mechanisms are provided for a user equipment (ue) to determine a user equipment (ue) location in a non-terrestrial wireless network (ntn) based on a reference signal time difference (rstd). a rstd is determined based on a sending time difference and a receiving time difference, where the sending time difference is a time difference between a first sending time instance when a first subframe of a first position reference signal (prs) is sent, and a second sending time instance when a second subframe of a second prs is sent. in addition, the receiving time difference is a time difference between a first receiving time instance when the first subframe of the first prs is received, and a second receiving time instance when the second subframe of the second prs is received.
