    Abstract: Apparatus and methods to support parallel communication using multiple subscriber identities in a wireless communication device via multiple subscriber identity modules (SIMs) are disclosed. A representative method includes establishing a connection with a first wireless network via a first wireless cellular protocol software stack for a first subscriber identity associated with a first subscriber identity module; registering with a second wireless network via a second wireless cellular protocol software stack for a second subscriber identity associated with a second subscriber identity module; and receiving radio frequency signals from the second wireless network via the second wireless cellular protocol software stack in parallel with communicating with the first wireless network via the first wireless cellular protocol software stack. The first and second wireless cellular protocol software stacks share at least a portion of radio frequency wireless circuitry for communicating with the first and second wireless network respectively.

    Abstract: A method for reducing network service scan time by a wireless communication device is provided. The method can include the wireless communication device determining a location of the wireless communication device. The method can further include the wireless communication devices selecting a subset of RATs supported by the wireless communication device based at least in part on the location of the wireless communication device and on deployment mapping information. The selected subset can include only one or more RATs indicated by the deployment mapping information to be deployed in the location of the wireless communication device. The method can further include the wireless communication device performing a service scan for at least one RAT included in the selected subset. Any RAT of the RATs supported by the wireless communication device that is not included in the selected subset can be excluded from the service scan.

    Abstract: A user equipment (UE) communicating in a wireless communication system may include a primary radio frequency (RF) receive chain (PRFRC) and one or more secondary RF receive chains (SRFRCs). When the UE is to undertake a circuit switched fallback (CSFB) process, the UE may use the one or more SRFRCs to search for candidate 2G/3G cells while in parallel using the PRFRC to wait for an ESR response. The UE may initiate a CSFB process and send an extended service request (ESR) message on a packet-switched network. The UE may monitor for receipt of an ESR response on the packet-switched network using a first RF receive chain, and while monitoring, also acquire an initial circuit-switched network using a second RF receive chain. The UE may start an ESR timer when sending the ESR message, and detect whether the ESR timer expires before the ESR response is received.

    Abstract: A method for selectively reading system information is provided. The method can include a wireless communication device reading system information broadcast by a first cell in a cell group. The read system information can include cell group information identifying the first cell as a member of the cell group and indicating membership of the cell group. The method can further include the wireless communication device moving to a second cell; determining based on the cell group information that the second cell is a member of the cell group; and in response to determining that the second cell is also a member of the cell group, reading only a portion of system information broadcast by the second cell. The read portion of system information can include the system information broadcast by the second cell that is different from the system information broadcast by the first cell.

    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: 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.
