Abstract: Techniques for random access (RA) in a cellular internet-of-things (CIOT) are discussed. An example apparatus configured to be employed within a User Equipment (UE), comprises a receiver circuitry, a processor, and transmitter circuitry. The receiver circuitry is configured to receive RA resource allocation information via one of a system information message or a downlink control information (DCI) message. The processor is operably coupled to the receiver circuitry and configured to: select a RA preamble sequence; generate a payload; and spread the payload via a spreading sequence. The transmitter circuitry is configured to transmit, based on the RA resource allocation information, a RA message comprising the RA preamble sequence and the payload, wherein the RA message is transmitted in a RA slot. The receiver circuitry is further configured to receive a response comprising a device identity of the UE and one of an uplink (UL) grant or a RA reject message.

Abstract: A base station can obtain channel quality conditions for mobile devices in a scheduling interval and identify a channel quality, a target transmission scheme, and a transmission power level for each of the mobile devices. The base station can assign a unique orthogonal CDMA code and can force the mobile devices to transmit K repeated bursts of uplink data such that each of the mobile devices has a rotated phase shift based on the unique orthogonal CDMA code assigned to each of the mobile devices with each of the mobile devices multiplexed on a same physical channel using an overlaid CDMA operation. The base station can process K repeated bursts that are multiplexed on the same physical channel using the overlaid CDMA operation. The base station can separate the mobile devices according to the unique orthogonal CDMA code and use IQ accumulation according to combine the K repeated bursts.
