1. A method, comprising:
at a user equipment (UE) associated with a base station, the UE and the base station configured with a Discontinuous Reception (DRX) functionality, the DRX functionality including a plurality of onDurations, wherein the UE is configured to monitor for downlink signals during each of the plurality of onDurations:
receiving an indication of at least one parameter the base station is to utilize for the transmission of an emergency message while the UE is operating in radio resource control (RRC) idle state;
receiving a system information block (SIB) modification, wherein the SIB modification indicates that the at least one parameter has been modified by the base station;
generating an emergency message monitoring schedule based on the indication of the at least one parameter, wherein the emergency message monitoring schedule includes a first subset of the plurality of onDurations aligned with time durations the base station is scheduled and omits a second subset of the plurality of onDurations; and
activating a mode of operation for monitoring for the emergency message where the UE configures the DRX functionality based on the emergency message monitoring schedule.
