Schemes on gnss position fix in connected in iot ntn

A method, comprising:

• receiving, by a base station, global navigation satellite system (GNSS) assistance information from a user equipment (UE) in a non-terrestrial network (NTN), wherein the GNSS assistance information includes a GNSS position fix time duration for measurement;
• determining one or more network scheduled durations for GNSS measurement for the UE based on the received GNSS assistance information, wherein the network scheduled duration for GNSS measurement is configured to enable the UE to re-acquire a GNSS position fix in a UE RRC_CONNECTED state;
• and
• transmitting the network scheduled duration for GNSS measurement to the UE.

A user equipment (UE), comprising:

• a transceiver that transmits and receives radio frequency (RF) signal in a non-terrestrial network (NTN) wireless system;
• an assistance information module that reports global navigation satellite system (GNSS) assistance information to a network entity in the NTN wireless system, wherein the GNSS assistance information includes a GNSS position fix time duration for measurement;
• a detection module that detects one or more GNSS position measurement triggering conditions in an RRC_CONNECTED state;
• a determination module that determines whether GNSS position fix time duration for measurement is smaller than a network scheduled duration for GNSS measurement, wherein the network scheduled duration for GNSS measurement is configured for the UE to re-acquire GNSS position fix in the RRC_CONNECTED state and is based on the UE reported GNSS position fix time duration for measurement;
• and
• a GNSS control module that performs a GNSS position fix acquisition procedure in the RRC_CONNECTED state when the GNSS position fix time duration for measurement is smaller than the network scheduled GNSS duration for GNSS measurement, otherwise, leaving the RRC_CONNECTED and performing the GNSS position fix acquisition procedure in RRC_IDLE.
