Broadcasting of a non-terrestrial network system information block

An apparatus for wireless communication, comprising:

• one or more memories comprising instructions;
• and
• one or more processors configured to execute the instructions and cause the apparatus to:
• obtain a system information block (SIB) that indicates information relating to one or more non-terrestrial network (NTN) SIBs that are to include at least one of ephemeris information or feeder link timing advance information;
• obtain the one or more NTN SIBs based at least in part on the information,
• wherein at least one of:
• a reference time for the at least one of the ephemeris information or the feeder link timing advance information to be included in the one or more NTN SIBs is based at least in part on a particular downlink transmit timepoint,
• an update to the at least one of the ephemeris information or the feeder link timing advance information is independent of triggering a system information update procedure, or
• the one or more NTN SIBs include a single NTN SIB that includes the ephemeris information and the feeder link timing advance information;
• and
• communicate with one or more entities of an NTN based at least in part on the one or more NTN SIBs.

One or more apparatuses for wireless communication, comprising:

• one or more memories comprising instructions;
• and
• one or more processors configured to execute the instructions and cause the one or more apparatuses to:
• output for transmission to a user equipment (UE) a system information block (SIB) that indicates information relating to one or more non-terrestrial network (NTN) SIBs that are to include at least one of ephemeris information or feeder link timing advance information;
• output for transmission to the UE the one or more NTN SIBs based at least in part on the information,
• wherein at least one of:
• a reference time for the at least one of the ephemeris information or the feeder link timing advance information to be included in the one or more NTN SIBs is based at least in part on a particular downlink transmit timepoint,
• an update to the at least one of the ephemeris information or the feeder link timing advance information is independent of triggering a system information update procedure, or
• the one or more NTN SIBs include a single NTN SIB that includes the ephemeris information and the feeder link timing advance information;
• and
• communicate with the UE based at least in part on the one or more NTN SIBs.

A method of wireless communication at a user equipment (UE), comprising:

• obtaining, a system information block (SIB) that indicates information relating to one or more non-terrestrial network (NTN) SIBs that are to include at least one of ephemeris information or feeder link timing advance information;
• obtaining the one or more NTN SIBs based at least in part on the information,
• wherein at least one of:
• a reference time for the at least one of the ephemeris information or the feeder link timing advance information to be included in the one or more NTN SIBs is based at least in part on a particular downlink transmit timepoint,
• an update to the at least one of the ephemeris information or the feeder link timing advance information is independent of triggering a system information update procedure, or
• the one or more NTN SIBs include a single NTN SIB that includes the ephemeris information and the feeder link timing advance information;
• and
• communicating with an NTN based at least in part on the one or more NTN SIBs.
