  • Patent number: 11140634
    Abstract: An apparatus of a Narrowband Internet-of-Things (NB-IoT) user equipment (UE) includes processing circuitry. To configure the NB-IoT UE for open loop transmit power control, the processing circuitry is to decode a narrowband system information block (NB-SIB) to obtain a narrowband physical random access channel (NPRACH) resource set and power control information associated with the NPRACH resource set. A random access channel (RACH) preamble is encoded for transmission with or without repetitions to a base station during a RACH procedure and using the NPRACH resource set. The transmission has transmission power based on the power control information. A narrowband uplink resource assignment received during the RACH procedure is decoded. A connection setup completion message is encoded for transmission to the base station using the narrowband uplink resource assignment.
