Abstract: Generating and using a device-type specific preferred public land mobile network (PLMN) list for roaming PLMN selection. Wireless devices sharing one or more common characteristics may be tasked with collecting roaming PLMN selection data. That data may be collected and used to generate a preferred PLMN list specific to wireless devices sharing those common characteristics. The preferred PLMN list may be distributed to wireless devices sharing those common characteristics, which may then use it in conjunction with roaming PLMN selection.

Abstract: A method for returning to a first network from a second network after premature termination of a CSFB voice call is provided. The method can include a wireless communication device storing cell information for the first network while connected to the first network; participating in a CSFB procedure to transition to the second network in response to initiation of a voice call; and determining that the voice call has prematurely terminated. In response to premature termination of the voice call, the method can further include performing a scan for a first network cell based on stored cell information for up to a maximum scan time period; reselecting to a first network cell in an instance in which a first network cell is identified by the scan; and camping on the second network in an instance in which a first network cell is not identified by the scan.

Abstract: Techniques for low power voice communications include determining a time between an arrival of data for uplink transmission by a device and a scheduling request (SR) occasion, the SR occasion occurring after the arrival of the data and within an on duration of a discontinuous reception (DRX) cycle, and delaying transmission of a SR by the device during a time period that begins at the arrival of the data for uplink transmission and continues for the determined time.

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).

Abstract: An electronic device receives an indication of a number of physical resource blocks and subcarrier spacing of at least a portion of a transmission channel and determines a dynamic transmission bandwidth, or receives an indication of a modulation coding scheme of the transmission channel and determines a modulation order. The electronic device transmits, using a transmitter, a signal over at least the portion of the transmission channel based on the dynamic transmission bandwidth being less than or equal to a threshold bandwidth, or the modulation order not corresponding to an additional power backoff, using a first power based on a maximum output power capacity of the electronic device and a maximum power reduction. Otherwise, the electronic device transmits the signal over at least the portion of the transmission channel at a second power based on the maximum output power capacity, the maximum power reduction and the additional power backoff.

Abstract: Devices and associated methods for operating a dual-subscriber identity module (SIM) dual-standby (DSDS) user equipment device (UE) configured with a first SIM and a second SIM. The UE performs communications with a first cellular network using the first SIM and a first radio resource control (RRC) connection, and receives a request to perform a higher priority communication using the second SIM. In response to the request to perform the higher priority communication, the UE transmits a request to the first network to suspend the first RRC connection. After transmission of the request to suspend the first RRC connection, the UE receives a message from the first network to place the first RRC connection in an inactive state, and initiates a timer, wherein the timer is used to determine whether the first RRC connection remains in the inactive state or transitions to an idle state.

Abstract: This disclosure relates to techniques for performing radio link monitoring and cell searching when moving at high speeds. A movement speed of a wireless device may be determined. When performing a cell search, the manner of the cell search may depend on the movement speed of the wireless device, potentially including cells that are associated with high movement speed being more highly prioritized when the wireless device is determined to be at a higher movement speed than when the wireless device is determined to be at a lower movement speed.
