Abstract: An electronic device may include wireless circuitry having one or more radios and one or more antennas. For some device configurations such as during a device low-power mode, a radio (operating in a radio on-off mode) may alternate between on and off states based on a duty cycle to reduce power consumption and increase device battery life. Radio operation in the on-off mode and device operation in the low-power mode may accommodate other radio operations such as emergency broadcast message reception, radio operations under an allocated power budge, user equipment periodic registration and update operations.

Abstract: A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.

Abstract: A method is disclosed where a user equipment (“UE”) determines that the UE is in a connected mode. The UE then determines a connection type of the connected mode and prioritizes a measurement report based on the connection type. The method may also be performed by an integrated circuit of the UE.

Abstract: Apparatuses, systems, and methods for enhancement of MBMS transmission reliability. A UE may receive PDCP PDUs via a PTM link from a network. The UE may determine to provide feedback regarding receipt of the PDCP PDUs, e.g., based, at least in part, on an occurrence of a triggering event. The triggering event may be configured by the network and may include the UE receiving a request for feedback from the network, the UE determining that at least one PDCP PDU is missing, the UE determining that a number of missing PDCP PDUs exceeds a threshold, and/or the UE determining that a PDCP reordering window is changing based on expiration of a PDCP reordering timer. The UE may transmit feedback associated with receipt of the PDCP PDUs. The feedback may include an indication of missing PDCP PDUs, e.g., such as an indication of a sequence number associated with missing PDCP PDUs.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods to implement mechanisms for non-stand-alone unlicensed band cells that support single carrier capable UEs. A UE may camp on a licensed band cell of a RAN and transmit a request to connect. The UE may receive, from the licensed band cell, a connection setup message indicating a switch to an unlicensed band cell of the RAN and receive, from the unlicensed band cell, a reference signal. The UE may transmit to the unlicensed band cell and in response to confirming, based at least in part of the reference signal, radio quality and/or downlink timing of the unlicensed band cell, a connection complete/connection resume message.

Abstract: A user equipment (UE) includes first and second subscriber identity modules (SIMs), possibly subscribed to different carriers. When the first SIM is in a connected state and the second SIM is in an idle state, the UE may need to periodically tune away a radio from a first frequency used for communication under the first SIM to a second frequency used for idle mode activity under the second SIM. The UE may provide to the network of the first SIM the second SIMs traffic activity pattern and/or serving frequency so that the network may provide coordinated configuration and/or scheduling for the UE device, e.g., in order to make the action of tuning away (and tuning back) the radio more efficient and/or to decrease the network impact of such radio tune aways (e.g., to decrease wasted uplink scheduling and wasted downlink transmissions for the first SIM).
