摘要: Techniques discussed herein may better ensure proper timing and synchronization of transmissions within a wireless communications network that includes a terrestrial network and a non-terrestrial network (NTN). A user equipment (UE) may maintain (e.g., determine and update on an ongoing basis) a timing advance (TA) value that the UE may apply to uplink (UL) transmissions to account for propagation delays, including changes in propagation delays, between the UE, NTN, and terrestrial network. TA maintenance may be based on network broadcasts, random access channel (RACH) procedures, control messages, timing drift rates (e.g., of the UE or NTN satellite), beam switching, and more.
