Channel configuration and dlul configuration for nb-iot-u system

A non-transitory machine-readable storage device including instructions stored thereon that, when executed by a narrowband internet of things user equipment (NB-IoT UE), configure the NB-IoT UE to perform operations comprising:

• receiving, from a radio access network (RAN), a master information block (MIB) comprising a downlink (DL)/uplink (UL) configuration for communication with the RAN and timing information carried in a narrowband physical broadcast channel (NPBCH), the DL/UL configuration and timing information received in an anchor segment of a NB anchor channel in an unlicensed band, the NB anchor channel fixed over time;
• determining, from the timing information and preconfigured frequency hopping information, a frequency hopping sequence among NB data channels;
• and
• after reception of the anchor segment, communicating data with the RAN in data segments on the NB data channels by frequency hopping among the NB data channels in accordance with the frequency hopping sequence.

An apparatus of radio access network (RAN) node, comprising:

• processing circuitry arranged to:
• encode a master information block (MIB) comprising a downlink (DL)/uplink (UL) configuration for communication with a narrowband internet of things user equipment (NB-IoT UE) and timing information carried in a narrowband physical broadcast channel (NPBCH), the DL/UL configuration and timing information transmitted in an anchor segment of an NB anchor channel in an unlicensed band, the NB anchor channel fixed over time;
• and
• communicate data with the NB-IoT UE in data segments on NB data channels in accordance with frequency hopping and the DL/UL configuration, wherein the NB data channel for data communication is selected in accordance with frequency hopping information;
• and
• a memory configured to store the frequency hopping information used to determine the frequency hopping.
