Title: MULTEFIRE DESIGN OF RANDOM ACCESS CHANNEL AND RANDOM ACCESS CHANNEL PROCEDURE FOR INTERNET OF THINGS DEVICE OPERATION IN UNLICENSED SPECTRUM
Abstract:
Systems and methods of performing a RACH procedure in a MulteFire scenario are described. An eMTC UE communicates with an eNB on an anchor channel at a predetermined frequency of an unlicensed band and data channels on other frequency hopping channels of the unlicensed band. The UE receives a PBCH signal with System Information Broadcast Anchor (SIB-A-MF) scheduling information, and a SIB-A-MF after the PBCH. The SIB-A-MF indicates a RAC) resource configuration for a RACH procedure and dwell time of the data channels. The dwell time of the anchor channel is smaller than that of the data channels. The anchor channel includes a UL RACH resource for transmission of a RACH Request. The UE transmits UL RACH messages on UL resources indicated by the SIB-A-MF and receives DL RACH messages on different data channels.
