Timing offset selection in non-terrestrial network

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• receive a message, comprising downlink control information (DCI) that is scrambled with a type of radio network temporary identifier (RNTI);
• and
• transmit to a network entity of a non-terrestrial network (NTN), using a cell-specific timing offset based at least in part on the type of RNTI, a physical uplink shared channel (PUSCH) communication in association with one or more of initial access or random access, wherein the cell-specific timing offset is included in a previously received message and the cell-specific timing offset accounts for a propagation delay between the network entity of the NTN and the UE.

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors;
• coupled to the memory, the one or more processors configured to:
• receive a message, comprising a medium access control control element (MAC CE), that indicates a UE-specific timing offset, wherein the UE-specific timing offset accounts for a propagation delay between a network entity of a non-terrestrial network (NTN) and the UE;
• and
• transmit to the network entity, using the UE-specific timing offset, a physical uplink shared channel (PUSCH) communication scheduled by a configured grant.
