Abstract: A basestation (e.g., a gNodeB) may transmit transmission scheduling information (such as downlink control information) to user equipment (UE). The basestation may include repetition related parameters (such as repetition numbers, aggregation factors, or other repetition information) for transmission repetition control within the transmission scheduling information.

Abstract: Techniques are described for selecting root pairs for Zadoff-Chu sequences for random access preamble and for signaling one or more values associated with the root pair to a user equipment (UE) by a base station. The described root pair selection methods for two-root physical random access channel (PRACH) preamble can enable the peak differences received at the UE from different frequency offsets (FOs) to be disjointed even considering error in UE side. The selection techniques can improve the performance of PRACH FO and time offset (TO) estimation.
