Abstract: A connection with a network that includes a base station (BS) may be established by a user device (UE) via a wireless connection, for conducting communications using semi persistent scheduling (SPS) in a connected discontinuous reception (C-DRX) mode. The SPS transmit periodicity may be adjusted with respect to the SPS activation command and the SPS interval UL (for uplink). Data may then be transmitted during the C-DRX On-Duration periods according to the determined SPS transmit periodicity. In some embodiments, the SPS transmit periodicity is adjusted such that following a first C-DRX On-Duration period when an SPS activation command is received, SPS data transmission occurs a specified number of subframes earlier during each subsequent C-DRX On-Duration period than in the first C-DRX On-Duration period. The SPS data transmission in each subsequent C-DRX On-Duration period may take place as soon as the UE device wakes up during the On-Duration period.

Abstract: Apparatuses, systems, and methods for user equipment (UE) devices to determine that it does not have cellular service and perform one or more searches for a mobile country code (MCC). The searches may include searches based on cellular modes, radio access technologies (RATs), and/or cellular bands. The UE may determine the MCC based on results of the one or more searches and perform a targeted service acquisition search based on, and limited by, the MCC. The MCC may be associated with one or more cellular modes, RATs, and/or cellular bands via a data structure that maps the MCC to the one or more cellular modes, RATs, and/or cellular bands. The targeted service acquisition search may include at least one RAT and one or more cellular bands within the at least one RAT associated with the MCC.

Abstract: Performing cell re-selection by a wireless user equipment (UE) device. A first cell on which to camp may be selected. The UE may camp on the first cell in an idle-mode. The UE may be configured to perform searches for neighboring cells according to an idle-mode timeline while camping on the first cell. The UE may transmit a connection request to the first cell in order to transition the UE from the idle-mode to a connected-mode via the first cell. One or more searches for neighboring cells may be performed according to a connected-mode timeline after transmitting the connection request, in response to transmitting the connection request. The one or more searches may be performed before the UE establishes the connected-mode with the first cell.

Abstract: A method for reducing power consumption by a wireless communication device is disclosed. The method can include the wireless communication device determining that the device is experiencing an uplink power limited condition. In an instance in which the connection to the serving network was established only for a signaling purpose, the method can further include the wireless communication device sending a measurement report including an actual measured downlink signal quality value for the serving network in response to the uplink power limited condition. However, if the connection to the serving network was not established only for a signaling purpose, the method can include the wireless communication device sending a measurement report including a modified downlink signal quality value for the serving network to trigger a handover in response to the uplink power limited condition.

Abstract: In some implementations, radio access technology (RAT) signals can be monitored and used to synchronize an internal clock of a mobile device to a network system clock without registering the mobile device to the network. In some implementations, a RAT processor can be configured to receive RAT signals and to prevent transmission of RAT signals. In some implementations, the internal clock can be associated with a GNSS processor and can be used to calculate a location of the mobile device. In some implementations, a RAT processor that is configured for a particular radio access technology can be configured to monitor signals associated with another radio access technology when synchronizing the internal clock. In some implementations, the RAT processor can monitor signals in response to a power event. The power event can be associated with powering a display of the mobile device.
