    Abstract: Apparatuses, systems, and methods for multi-SIM user equipment (UE) devices to perform emergency calling. A UE may receive an indication to initiate an emergency call. The UE may select a cell on which to initiate the emergency call. If a serving cell of a first SIM of the UE is not available for the emergency call, the UE may utilize information from a second SIM of the UE as part of selecting the cell on which to initiate the emergency call. The information from the second SIM may include an indication of a serving cell of the second SIM. Alternatively or in addition, the information from the second SIM may include an indication of one or more neighboring cells of the second SIM. The emergency call may be initiated via the selected cell using the first SIM.

    Abstract: Mechanisms enabling link-budget-limited (LBL) devices to more effectively perform random access may include: (1) broadcasting a Physical Random Access Channel (PRACH) configuration index (PCI) reserved for LBL devices; (2) configuring LBL devices to use a PCI that is offset from the conventional PCI of current cell; (3) configuring LBL devices to transmit PRACH messages using an alternative set of subframes, different from conventionally-defined subframe set; (4) configuring LBL devices to transmit PRACH messages on odd frames when the conventional PRACH configuration specifies even frames; (5) configuring LBL devices to generate and use extra PRACH preambles that are not used by non-LBL devices; (6) configuring LBL devices to use group B preambles while non-LBL devices are configured to use group A preambles; and (7) boosting power of a random access response message after an Nth random access failure with preamble conforming to an LBL-reserved pattern of preambles.

    Abstract: Apparatuses, systems, and methods for multi-SIM user equipment (UE) devices to perform system selection. A UE may determine to perform system selection for a first SIM of the UE. Information, such as serving cell and/or neighboring cell information, may be obtained from a second SIM of the UE. System selection for the first SIM may be performed based at least in part on the information obtained from the second SIM.

    Abstract: Methods, apparatuses and computer readable media are described that manage transmit power levels for a wireless device connected to a network access system of a wireless network. Processing circuitry in the wireless device obtains a target average transmit power level. Based on estimates of an actual average transmit power level for a sliding window of a past time period and the target average transmit power level, the processing circuitry determines a target transmit power level, a duty cycle percentage, and a transmit pattern of transmit on frames and transmit off frames for a future time period. The processing circuitry sends to the access network system signaling messages indicating non-zero valued buffer status reports for the transmit on frames and zero valued buffer status reports for the transmit off frames. Non-zero values correspond to actual amounts of pending uplink data, while zero values are sent irrespective of actual uplink buffer status.

    Abstract: Methods, apparatuses and computer readable media are described that configure wireless circuitry of a wireless communication device connected to a wireless network. Processing circuitry in the wireless communication device establishes a connection to a access network subsystem of the wireless network using a plurality of radio frequency carriers and provides an indication of wireless circuitry included therein. The wireless network provides a measurement gap configuration, and the wireless communication device suspends communication on at least one carrier and measures signals from one or more additional access network subsystems during a measurement gap time period. The wireless communication device provides a measurement report to the access network subsystem based at least in part on measured signals. In an embodiment, the wireless communication device also receives downlink communication from the wireless network during at least a portion of the measurement gap time period.
