    Abstract: When embedding a signal into a selected subcarrier of a multicarrier downlink waveform of regular data/control signaling, a base station modulates the embedded signal with a different modulation scheme than the other data in the downlink waveform. The base station nulls adjacent subcarriers to minimize interference at a low-power wake-up receiver of an IOE device(s). The IOE device wakes up the low-power wake-up receiver at scheduled times to listen for the signal. For synchronization signals, the IOE device corrects a local clock based on a correlation value of the signal to a predetermined sequence. For wake-up signals, the IOE device correlates whatever is detected at the antenna to a predetermined sequence and compares the correlation value to a predetermined threshold. If the threshold is met, the IOE device registers a wake-up signal and wakes the primary transceiver of the device. If not, the receiver goes back to sleep.

    Abstract: Some aspects of the present disclosure provide for methods, apparatus, and computer software for low-power synchronization of wireless communication devices. In one example, an asynchronous code division multiple access (CDMA) channel may be utilized for uplink communication. By utilizing asynchronous CDMA on the uplink, synchronization requirements are relaxed relative to other forms of communication. Accordingly, a synchronization period after coming out of a sleep state can be short, reducing power consumption during re-synchronization. In another example, a low-power companion receiver, rather than the full-power WWAN receiver, may be utilized to acquire a sync signal while the device is in its sleep state. Once synchronism is achieved via the low-power companion receiver, the full-power radio may power up and perform communication with the network. By shifting the synchronization from the full-power radio to the low-power companion radio, power consumption during re-synchronization can be achieved.

    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a downlink (DL) reception indication during an active duration of a discontinuous reception (DRX) configuration. The DL reception indication may indicate the presence of a reception opportunity following an inactivity interval, as well as the length of the inactivity interval. The wireless device may refrain from DL monitoring during the inactivity interval. In some cases, the wireless device may enter a sleep mode during the inactivity interval and wake up to receive a subsequent transmission during the reception opportunity. In some examples, the wireless device may use the inactivity interval to communicate using a different radio access technology (RAT).
