Abstract
The present disclosure relates to wireless communications, and more particularly to enhancements to a random access channel (RACH) procedure for use in New Radio (e.g., 5G) communications in the unlicensed spectrum (also referred to as NR-U). The present disclosure provides a user equipment (UE) or network entity that determines an available RACH occasion (RO) within a slot for a message transmission according to one of a two-step RACH procedure or a four-step RACH procedure, wherein the available RO is adjacent to at least one unavailable RO within the slot. The UE or network entity may further perform, during the RO, the message transmission according to one of the two-step RACH procedure or the four-step RACH procedure.
