Abstract

Described is an Evolved Node-B (eNB) comprising one or more processors to generate a first transmission for a first Cellular Internet-of-Things (CIoT) device and a second transmission for a second CIoT device. The first transmission may be generated for a first Narrowband (NB) channel, and the second transmission may be generated for a second NB channel. The first and second transmissions may include the same set of system information. Also described is a CIoT device comprising one or more processors to to process a System Information (SI) transmission on one of a plurality of NB channels, and to process and extract information from a PSS and/or SSS transmission on a set of subcarriers corresponding to a set of frequency bands. The plurality of NB channels are within a wireless communication system bandwidth, and at least two of the plurality of NB channels correspond to portions of the wireless communication system bandwidth outside the set of frequency bands.
