ENABLING INITIATING DEVICE FOR UES OPERATING IN INACTIVE MODE FOR URLLC OPERATING IN UNLICENSED SPECTRUM

摘要

An apparatus and system to permit a UE idle or inactive mode to operate as an URLLC initiating device operating in a shared spectrum in a PRACH procedure are described. The UE receives a gNB control signal that contains an indication that the UE is able to operate as an initiating device and in response transmits a physical random access channel (PRACH) message within a Fixed Frame Period (FFP) of the UE. Transmission of the PRACH message is contingent on non-overlap of the PRACH message transmission with the idle period of a gNB FFP.
