Abstract: Doppler pre-compensated control and data signal(s) generated using first and second Doppler pre-compensation patterns, respectively, are transmitted. A signal indicating the Doppler pre-compensation patterns is transmitted. The Doppler pre-compensated control signals comprise synchronization signals, system information blocks (SIBs), a radio resource control (RRC) message, or a physical downlink control channel (PDCCH), and the Doppler pre-compensated data signals comprise a physical downlink shared channel (PDSCH). The signal indicating the Doppler pre-compensation patterns comprises one of an RRC message or a PDCCH, and may indicate absolute Doppler values or a difference between Doppler values. The PDCCH may indicate a time offset between the PDCCH PDSCH.

Abstract: A synchronization signal block (SSB) including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a physical broadcast channel (PBCH) is transmitted using first and second beams. One or more symbols adjoining the first and second synchronization signals are configured to accommodate a beam switching time. At least one signal indicates a beam index for the first beam transmitting the first synchronization signal, and the beam index for the second beam transmitting the second synchronization signal is either signaled or determined based on a predetermined relationship between a resource for the first synchronization signal and a resource for the second synchronization signal. The beam indices may comprise first and second numbers of bits and/or may be jointly encoded. The beam indices may be indicated by one of the PSS, the SSS, the PBCH, a demodulation reference signal (DMRS), or a synchronization or reference signal designated for that purpose.

Abstract: Doppler pre-compensation is performed on synchronization signals using each of multiple Doppler pre-compensation patterns to generate a plurality of sets of Doppler pre-compensated synchronization signals that are transmitted using one or more beams. A signal indicating the Doppler pre-compensation patterns used is transmitted in one of a system information block (SIB) or a radio resource control (RRC) reconfiguration message, in connection with initial access by a user equipment (UE), idle UE cell reselection, connected UE data channel reception, or UE handover. The signal indicates Doppler pre-compensation patterns for a transmitting cell and Doppler pre-compensation patterns for one or more neighbor cells. The synchronization signal comprises a synchronization signal block (SSB) including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). Received Doppler pre-compensated synchronization signals are combined in the time domain in connection with timing synchronization detection, frequency offset (FO) estimation, or reference signal received power (RSRP) measurement.

Abstract: A non-terrestrial network (NTN) node transmits configuration information including an indication of a maximum transmission block size (TBS) for a physical uplink shared channel (PUSCH) transmission or a physical downlink shared channel (PDSCH). A TBS for the PUSCH or PDSCH is determined based on at least the indicated TBS, and one of a signal indicates one of a maximum modulation and coding scheme (MCS) for the PUSCH or PDSCH transmission or whether the PUSCH or PDSCH transmission uses a default MCS, or the MCS is determined based on at least the indicated maximum MCS, and the PUSCH is transmitted or the PDSCH is received based on the determined TBS and the determined MCS. A maximum TBS, a maximum MCS, or a number of hybrid automatic repeat request (HARD) processes is indicated by a master information block (MIB), a system information block (SIB), or radio resource control (RRC) signaling.
