    Abstract: Briefly, in accordance with one or more embodiments, a Cellular Internet of Things evolved Node B (CIoT eNB) comprises baseband processing circuitry to process a Cellular Internet of Things Application Protocol (CIAP) setup request message received from a CIoT gateway (CIoT GW), wherein the CIAP setup request message is to configure a reduced signaling overhead between the CIoT eNB and the CIoT GW, and generate a CIAP setup response message to be transmitted to the CIoT GW in response to the CIAP setup request message. In other embodiments, a Cellular Internet of Things gateway (CIoT GW) comprises baseband processing circuitry to generate a Cellular Internet of Things Application Protocol (CIAP) setup request message to be transmitted to a CIoT evolved Node B (CIoT eNB), and process a CIAP setup response message received from the CIoT eNB in response to the CIAP setup request message.
