Abstract: Various embodiments provide methods implemented by a processor executing on a mobile communication device (e.g., a multi-SIM-multi-active communication device) to opportunistically schedule a victim subscription's power monitoring activities to occur during periods in which the aggressor subscription is already scheduled not to transmit, thereby reducing the amount of time the aggressor subscription must perform Tx blanking to accommodate the victim subscription's idle-standby-mode operations. Specifically, the victim subscription's monitoring activities may be scheduled to occur while the aggressor subscription is operating in a compressed mode. As a result, the overall throughput/performance of an aggressor subscription is improved as the aggressor experiences relatively fewer blanked transmissions without affecting the victim subscription's ability to perform power-monitoring operations.

Abstract translation: 各种实施例提供了通过在移动通信设备（例如，多SIM多活动通信设备）上执行的处理器实现的方法来机会地调度受害者订阅的电力监视活动，以在攻击者订阅已经被调度的时段期间发生 从而减少攻击者订阅必须执行Tx消隐的时间，以适应受害者订阅的空闲待机模式操作。 具体来说，受害者订阅的监视活动可能被安排在攻击者订阅以压缩模式运行时发生。 因此，攻击者订阅的总体吞吐量/性能得到改善，因为侵略者经历相对较少的空白传输，而不影响受害者订阅执行电源监控操作的能力。

Abstract: Apparatus, methods, and computer-readable media for facilitating power savings while monitoring for paging messages and wakeup signals are disclosed herein. An example method for wireless communication at a UE includes receiving an indication of an active BWP associated with an ON duration of a DRX cycle. The example method also includes monitoring a first bandwidth for a WUS at a WUS occasion of the DRX cycle, the first bandwidth corresponding to a subset of the active BWP. The example method also includes transitioning to an awake state for the ON duration when the WUS is received at the WUS occasion.

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.

Abstract: Apparatuses and methods for a wireless communication device having multiple Subscriber Identity Modules (SIMs) in which a first SIM is associated with an Internet Protocol (IP) Multimedia Subsystem (IMS) subscription that supports IMS services. The method includes but not limited to, determining that an IMS activity has completed at the IMS subscription, and determining whether a timer for a scheduled IMS signaling exceeds a time threshold. The timer indicates a time duration until performing the scheduled IMS signaling as scheduled. The method further includes, in response to determining that the timer does not exceed the time threshold, performing the scheduled IMS signaling and releasing a connection for the IMS subscription.

Abstract: A method for performing cell reselection by a wireless communication device is described. The method includes determining that the wireless communication device should perform reselection to a target cell from a serving cell. The method also includes determining that the wireless communication device does not have paging channel information of the target cell. The method further includes prioritizing reading paging channel information from a broadcast channel of the target cell over reading a paging channel of the serving cell.

Abstract: Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) may be configured with multiple bandwidth parts (BWPs) and may support multiple subscriber identification modules (SIMs) (e.g., may operate in a multi-SIM (MSIM) mode). The UE may tune away from a default data SIM (DDS) subscription for a tune away gap and may miss any downlink signaling, such as an indication of a BWP switch, for a duration of the tune away. To avoid latency resulting from such missed downlink signaling, the UE may support a mechanism according to which the UE may autonomously switch to a different BWP despite a missed command from a network entity. Such a mechanism may include transmission of a scheduling request (SR) on each of multiple BWPs configured for the UE and monitoring each of the multiple BWPs for signaling responsive to the SR.
