Abstract: This disclosure relates to systems, apparatuses, and methods for coordinating communication and avoiding and/or mitigating collisions for multi-subscriber identity module devices in a wireless communication system. A wireless device may coordinate communication associated with different subscriber identity modules and/or may mitigate collisions between communications associated with different subscriber identity modules. A network may provide information to improve coordination and/or mitigate collisions. A network may adjust paging schedules and/or provision of alert messages to improve coordination.

Abstract: A device, system, and method detect an activity and utilize a mitigation scheme. The method is performed at a device that is configured to establish a network connection to a network, the network including a plurality of areas, each area being defined based on a grouping of a plurality of neighboring cells, the device being associated with one of the areas at a select time. The method includes determining between an activity status and a non-activity status associated with the device. When the activity status is determined, the method includes determining an area update rate indicating a number of changes to the associated area over a period of time. When the area update rate exceeds a predetermined update rate threshold, the method includes selecting a mitigation scheme configured to reduce an amount of power used by the device.

Abstract: A network controller, a user equipment (UE) device, and associated methods for adaptively prioritizing simultaneous unicast and multicast communications based on traffic classes. The UE may determine whether each of a unicast communication and a multicast communication are associated with a foreground application or a background application. The UE may further determine whether each of the unicast communication and the multicast communication are high priority or low priority. The UE may then buffer one of the unicast or multicast communications based on the whether it is associated with a foreground or background application, whether it is high or low priority, and whether it is a unicast or multicast communication.

Abstract: A device sets an activity mode for a cellular connection. A method to set the activity mode is performed at a device located with a user that is configured to establish a network connection to a network. The method includes determining a status of the user, the status indicating an activity state or a non-activity state of the user. The method includes, when the status indicates the activity state, activating an activity mode on the device that restricts select types of mobile originating data traffic.

Abstract: Techniques described herein may enable a user equipment (UE) to optimize radio access technology (RAT) and radio resources (e.g., bandwidth parts (BWPs)) when communicating with the network. This may be based on one or more factors or conditions, such as whether the UE is currently using 4th generation (4G) RAT or 5th generation (5G) RAT, whether the UE is in an active mode or idle mode, a BWP used by the UE, whether an application or network service requires a certain throughput, a type of application being used by the UE, an amount of network congestion, and so on. RAT optimization may also be based on whether the UE is using a frequency range 1 (FR1) or frequency range 2 (FR2), whether the UE is stationary or moving, whether the UE is experiencing beam failures, uplink (UL) switches, link quality measurements (LQMs), reference signal received power (RSRP) measurements, and so on.

Abstract: Disclosed are methods, systems, and computer-readable media to perform operations including: receiving an uplink grant associated with pre-scheduling from a base station; in response to the uplink grant, transmitting first data having a first priority to the base station; determining whether there is a remaining uplink resource associated with the uplink grant; and in response to determining that there is the remaining uplink resource, transmitting second data having a second priority to the base station using the remaining uplink resource, wherein the second priority is lower than the first priority.

Abstract: Disclosed are embodiments for reducing likelihood of selecting a cell identified by a Radio Access Network (RAN) Notification Area ID (RNA ID) that is different from that identifying a last or current serving cell so as to avoid an RNA update procedure; reducing Random Access Channel (RACH) transmissions for an RNA update procedure and a mobile originated (MO) data transmission in response to a Radio Resource Control (RRC) triggered RNA update procedure; and selecting a band or beam in a multi-band/beam cellular system that improves RACH efficiency.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including: determining that a user equipment (UE) is connected to a cell of a network using a connection in a standalone (SA) mode; based on determining a bandwidth part (BWP) of the connection, accessing a physical cell identifier (PCI) list associated with the UE for a time period; based on the number of PCI values in the list and a duration of the time period, assigning, to a BWP switch timer, a timeout value; initiating the BWP switch timer; and in response to determining that the handover of the UE to the different cell of the network occurs prior to the BWP switch timer reaching the timeout value, causing the UE to switch to a LTE mode.

Abstract: An electronic device having multiple antenna groups for data communication may determine a temperature of a first antenna group and determine a power gain of a second antenna group. The electronic device may communicate using the second antenna group in response to determining that the temperature of the first antenna group exceeds a temperature threshold and the power gain of the second antenna group exceeds a gain threshold. In some embodiments, the electronic device may receive communication link preferences, determine an antenna group that is disposed outside of thermal hotspots of the electronic device, and determine a beam that enables the communication link preferences via the antenna group. The electronic device may then transmit or receive data via the antenna group by forming the beam.
