Methods and apparatus for iot operation in unlicensed spectrum

A method of wireless communication via narrowband interne of things (NB IOT) in an unlicensed spectrum by a base station using digital modulation, comprising:

• configuring a plurality of downlink carriers in the unlicensed spectrum to occupy at least a first minimum bandwidth by the plurality of downlink carriers and a plurality of uplink carriers in the unlicensed spectrum to occupy at least a second minimum bandwidth with the plurality of uplink carriers;
• and
• performing communication using one or more of the plurality of downlink carriers and the plurality of uplink carriers.

A user equipment (UE) for wireless communication via narrowband internet of things (NB IOT) in an unlicensed spectrum using digital modulation, comprising:

• means for utilizing a plurality of downlink carriers in the unlicensed spectrum occupying at least a first minimum bandwidth by the plurality of downlink carriers and a plurality of uplink carriers in the unlicensed spectrum occupying at least a second minimum bandwidth with the plurality of uplink carriers;
• and
• means for performing communication using one or more of the plurality of downlink carriers and the plurality of uplink carriers.
