Abstract: Systems, apparatuses, methods, and computer products for fast wakeup recovery for narrow-band internet of things (NBIOT) systems are provided. The fast wakeup recovery may wakeup a NBIOT device from a sleep mode to an active mode. The fast wakeup recovery may identify a servicing cell for the NBIOT device to synchronize with. The fast wakeup recovery may be based on a coarse timing detection operation using a NPSS and a fine timing detection operation using a NSSS.

Abstract: Systems, apparatuses, methods, and computer products for cell quality measurements of for cellular internet of things (IOT) systems provided, including for cellular narrow-band IOT (NBIOT) systems and machine type communication (MTC) systems. For example, an IOT device may determine these cell quality measurements to select a serving cell to use for connecting to a cellular network. The cell quality measurements may include channel estimation that is used to generate an RSRP, RSRQ, and Noise Variance estimation. In various embodiments, and based on the cell quality measurements, an IOT device may rank a plurality of cells and select a top ranked cell for providing cellular service.
