Abstract: Embodiments of efeMTC synchronization signals for enhanced cell search and enhanced system information acquisition are described. In some embodiments, an apparatus of a base station (BS) is configured to generate a length-x sequence for an efeMTC synchronization signal, the length-x sequence configured for repetition in frequency domain within 6 physical resource blocks (PRB). In some embodiments, to generate the length-x sequence, the BS may be configured to select any one index of the set of root indices {1, 2, . . . , 63}, excluding the root indices 25, 29 and 34, to correspond to a different physical-layer cell identity (PCID). In some embodiments, the BS may be configured to encode RRC signaling to include a System Information Block (SIB) comprising configuration information for transmission of the efeMTC synchronization signal, and transmit the length-x sequence as the efeMTC synchronization signal in frequency resources according to the SIB.

Abstract: Embodiments may be directed to techniques to process a handover command message received from a source next generation node B (gNB), the handover command message comprising random-access channel (RACH) configuration information and determine at least one of dedicated RACH resources and common RACH resources to access a target gNB based on the RACH configuration information. Embodiments also include techniques to cause, via an interface, one or more attempts to access the target gNB utilizing at least one of the dedicated RACH resources and the common RACH resources.
