Abstract
A method for operating a user equipment (UE) comprises receiving system information including: information corresponding to location coordinates for a non-terrestrial network (NTN) gateway; information corresponding to a processing delay between the UE and a base station (BS); and information corresponding to a reference point location; determining a timing advance based on a timing difference between the reference point location and the BS; and transmitting a timing advance report based on the determined timing advance.
Claims20
A user equipment (UE), comprising:
- a transceiver configured to:
- receive system information including:
- information corresponding to location coordinates for a non-terrestrial network (NTN) gateway;
- information corresponding to a processing delay between the UE and a base station (BS);
- and
- information corresponding to a reference point location;
- and
- a processor operably connected to the transceiver, the processor configured to determine a timing advance based on a timing difference between the reference point location and the BS;
- wherein the transceiver is further configured to transmit a timing advance report based on the determined timing advance.
A base station (BS), comprising:
- a processor configured to:
- generate system information including:
- information corresponding to location coordinates for a non-terrestrial network (NTN) gateway;
- information corresponding to a processing delay between a user equipment (UE) and a base station;
- and
- information corresponding to a reference point location;
- and
- a transceiver operably connected to the processor, the transceiver configured to:
- transmit the system information;
- and
- receive a timing advance report based on a timing advance,
- wherein the timing advance is based on a timing difference between the reference point location and the base station.
A method for operating a user equipment (UE), the method comprising:
- receiving system information including:
- information corresponding to location coordinates for a non-terrestrial network (NTN) gateway;
- information corresponding to a processing delay between the UE and a base station (BS);
- and
- information corresponding to a reference point location;
- determining a timing advance based on a timing difference between the reference point location and the BS;
- and
- transmitting a timing advance report based on the determined timing advance.
