Abstract: Methods and apparatuses are described herein for synchronization enhancement in new radio non-terrestrial networks. In an example, a UE may determine a distance between the UE and a satellite of a NTN. The UE may determine a reference distance associated with the satellite. The UE may determine a differential delay associated with the UE based on the distance between the UE and the satellite and based on the reference distance. Based on the differential delay, the UE may determine a timing advance associated with the UE and the NTN.

Abstract: The present application describes an apparatus including a non-transitory memory including instructions stored thereon. The apparatus also includes a processor operably coupled to the non-transitory memory configured to execute a set of instructions. The instructions include sensing plural devices in a group to provide sidelink coordination. The instructions also include evaluating a coordination type of each of the plural devices, where the coordination type is scheduled and/or assisted. The instructions also include obtaining transmission and reception resources for the plural devices. The instruction further include determining the transmission and reception resources are dedicated or shared among the plural devices based on the coordination type. The instructions even further include determining a signaling type for each of the plural devices based on the coordination type.

Abstract: Methods, systems, and. devices may assist in new radio (NR) sidelink (SL) operation in licensed or unlicensed spectrum. In an example, if listen-before-talk (LBT) failure rate is low, then implicit acknowledgement (ACK) and explicit non-acknowledgement (NACK) may be used. A first SL timer may start when a. SL transport block is transmitted. If no explicit NACK, is received before the SL timer expires, then ACK. may be assumed. If LBT failure rate is high, then explicit ACK and implicit NACK may be used. A second SL timer may start. If no explicit ACK is received before the SL timer expires, then NACK may be assumed.

Abstract: Methods, apparatus, and systems are described for new radio (NR) sidelink resource allocation, e.g., for power saving and bandwidth part (BWP) operations. According to some aspects, different types of resource sets and signaling (e.g., preferred, non-preferred, resource conflict, etc.) may be considered and it may be indicated to user equipment (UE) which type of resources should be used based on certain criteria, e.g., least power consumption criteria.
