Abstract: Certain aspects of the present disclosure relate to a method and apparatus for communicating on an uplink between a user equipment and a gNB. In one example, the method and apparatus may include a UE waiting for an NPRACH occasion to transmit an NPRACH preamble, the UE monitoring the search space for (C-RNTI) NPDCCP candidates which carry UL grants, the UE aborting the opportunity to send the NPRACH preamble ifthe physical layer UE receives a UL grant, the UE sending UL data to the gNB, and the UE continuing to monitor the search space for valid C-RNTI NPDCCH candidates for DCI grants. Also, in another example, the UE calculates an NPDCCH search space start timing, monitors a RAR window start timing, and receives the RAR ifthe RAR window starts before the next NPDCCH search space.
