摘要： In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE determines multiple uplink measurement occasions for transmitting multiple reference signals to a satellite in a non-terrestrial network (NTN). The UE generates, based on Global Navigation Satellite System (GNSS) location data of the UE and ephemeris data of the satellite, multiple timing advance (TA) reports that are linked to the multiple uplink measurement occasions, respectively. The UE transmits the multiple TA reports to the satellite at multiple time points. The UE transmits the multiple uplink reference signals to the satellite on the uplink measurement occasions.

摘要： Various solutions for enhancements on integer cycle report for carrier phase positioning are described. An apparatus may receive a positioning reference signal (PRS) from a first network node of a wireless network. The apparatus may measure a carrier phase associated with a delay path and a transmission frequency point of the PRS. Then, the apparatus may report the carrier phase to a second network node of the wireless network.

摘要： Various solutions for physical random access channel (PRACH) timing advance operation and PRACH configurations with respect to user equipment and network apparatus are described. An apparatus may determine a propagation delay between the apparatus and a network node. The apparatus may determine a pre-compensation timing margin. The apparatus may perform a timing advance pre-compensation according to the propagation delay and the pre-compensation timing margin. The apparatus may transmit an uplink signal by applying the timing advance pre-compensation.
