Abstract: Methods, systems, and devices for wireless communications are described to support monitoring for paging messages from a base station (e.g., a cellular network node) using a greater periodicity than a discontinuous reception (DRX) cycle periodicity. A UE may monitor for and receive paging messages from a network node using a first subscription registered with a first radio access technology (RAT) while operating in DRX mode for a second RAT associated with the base station. The UE may identify a first periodicity for monitoring for paging messages from the base station that is greater than the DRX periodicity. The UE may have a second subscription that may be registered with a second base station. The UE may perform a tuneaway procedure from the second base station and monitor for paging messages from the base station according to the first periodicity.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support reselection procedures for power saving in industrial internet of things (IIoT) operations. In a first aspect, a method of wireless communication includes a user equipment (UE) setting a reselection flag to a no-reselection state either by default or in response to a source cell signal-to-noise ratio (SNR) exceeding a predetermined maximum SNR. The UE can set the flag to the allow-reselection state in response to the target cell SNR range exceeding the source cell SNR range or the source cell SNR being below a predetermined minimum SNR. The UE may then either reselect to the target cell when appropriate or maintain service on the source cell based on the state of the reselection flag. Other aspects and features are also claimed and described.

Abstract: A multi-subscriber identification module (SIM) wireless communication device with a first SIM and a second SIM associated with a shared radio frequency (RF) resource may determine that timing collisions are predicted between an active period of a discontinuous reception (DRX) cycle associated with the first SIM and an active period of a DRX cycle associated with the second SIM. In response, the wireless communication device may determine whether the first SIM is registered with an IP Multimedia Subsystem (IMS) to use Voice-over-wireless local area network (VoWLAN) service over a wireless local area network (WLAN). If the first SIM is registered with the IMS to use VoWLAN service over the WLAN, the wireless communication device may shift the conflicting DRX cycle associated with the first SIM by a time margin, and receive paging messages for mobile terminating calls on the modem stack associated with the first SIM over the WLAN.
