Consider power efficiency, wide and narrow beams are considered in NTN systems to achieve more efficient DL/UL transmission scheduling. However, there may be EIRP split issue for beam differentiation. For example, 50%EIRP are allocated for wide beam and 50%EIPR are allocated for narrow beam, then there may be -3db loss compared with no EIRP split. In view of mentioned issue, novel schemes for Synchronization signal and PBCH design in NTN are mentioned in this patent.

CELL SELECTION AND RESELECTION IN LEO-BASED NR-NTN
Methods for a New Radio (NR)-based, Low Earth Orbit (LEO) Non-Terrestrial Networks (NTN) are proposed to improve cell selection and reselection by using satellite assistance information. Different from traditional 5G New Radio systems, the LEO NTN can provide the next cell information along the satellite trajectory using System Information Broadcast (SIB). The assistance information can include satellite's long term ephemeris in the format of Position Velocity (PV) information or details of satellite's other orbital parameters.
