  • Publication number: 20250142470
    Abstract: The efficient usage of receivers for paging-early-indication (PEI) reception in a user equipment (UE) is described. The UE determines to use a wake-up receiver (WUR) as the primary receiver for monitoring PEO when waking up in Discontinuous Reception (DRX). The WUR consumes less power than a main receiver of the UE. The UE detects, at the WUR, a PEI and activates the main receiver of the UE for monitoring a paging occasion (PO). Responsive to determining that a condition for using the WUR as the primary receiver for monitoring PEI when waking up in DRX is not satisfied. the UE switches to using the main receiver as the primary receiver for monitoring PEI when waking up in DRX and not using the WUR for monitoring PEI.
