US 2026/0231024 A1 · CONFIGURATIONS FOR WAKE-UP SIGNALS WITH DISCONTINUOUS RECEPTION

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.

Dependent claims

A user equipment (UE), comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
receive, from a network entity, configuration information indicating a configuration of the UE to perform physical downlink control channel (PDCCH) monitoring during an inactive portion of a connected mode discontinuous reception period, the PDCCH monitoring triggered based at least in part on a wake-up signal received via a first radio component of the UE that consumes less operating power than a second radio component of the UE;
and
receive, from the network entity, a PDCCH during a PDCCH monitoring occasion that is triggered during a wake-up signal monitoring occasion, wherein the connected mode discontinuous reception period is an integer multiple of a first period of the PDCCH monitoring occasion or a second period of the wake-up signal monitoring occasion.
