Abstract: In some examples of the techniques described herein, the latency of connected mode discontinuous reception (C-DRX) may be reduced by utilizing a low power wake-up signal (LP-WUS). For instance, physical downlink control channel (PDCCH) monitoring may be triggered based on the LP-WUS with the C-DRX configuration as a power saving procedure for a radio resource control (RRC) connected mode. In some approaches, the cycles of the additional PDCCH monitoring triggered by LP-WUS may be coordinated with C-DRX cycles. For example, an LP-WUS PDCCH monitoring cycle may evenly divide the C-DRX cycle. Utilizing the even division may allow, in one or more C-DRX cycles, a UE to perform a radio resource management (RRM) measurement in one or more time durations in which UE does not monitor the PDCCH. For instance, the RRM measurement procedure may be improved by reducing complexity of time durations in which RRM measurement may be performed.

Abstract: Aspects of the disclosure are directed to methods and apparatus for time and frequency synchronization during a low-power wake up signal (LP-WUS) procedure. For example, an LP-WUS procedure may include transmission of signaling modulated via on-off keying (OOK). Such a signal requires less processing relative to an orthogonal frequency division multiplexing (OFDM) modulated signal and can be used to notify a wireless node that the transmitting device has data to transmit to the wireless node via an OFDM transmission. Accordingly, in response to the LP-WUS signal, the wireless node may power-on a main radio capable of receiving and demodulating the OFDM transmission.
