Abstract:
This disclosure relates to techniques for handling voice and data under uplink limited conditions in a wireless communication system. A wireless device and a base station may establish a wireless communication link. Transmission time interval bundling (TTI-B) may be enabled for uplink communications between the wireless device and the base station. It may be determined that the wireless device is experiencing uplink limited conditions. One or more rules prioritizing a first type of data over a second type of data for uplink communications may be enabled based on TTI-B being enabled and the wireless device experiencing uplink limited conditions.
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.
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:
Methods, apparatuses and computer readable media are described that adjust radio resource control connection states between a mobile wireless device and a wireless network following determination that a set of inactivity trigger conditions is met. Time periods between successive data messages and/or signaling messages transmitted to and/or received from a wireless access network are measured. When a prolonged period of data inactivity and/or signaling activity is determined, the mobile wireless device re-establishes an existing radio resource control connection to the wireless access network or releases the radio resource control connection to the wireless access network and transitions to an idle state.
Abstract:
A wireless communication system is presented in which user equipment (UE) performs non-intra-frequency (NIF) cell reselection. The NIF cell reselection process can: detect, on a discontinues reception (DRX) cycle, whether a NIF for a second cell has passed a second reselection threshold; perform, on the DRX cycle, additional checks or measurements to determine whether a higher priority NIF for a third cell has passed a third reselection threshold; and continue a cell reselection process for the second cell and the third cell. The NIF cell reselection techniques can help ensure that the UE reselects to higher priority cells without expending an unnecessary amount power.
Abstract:
Improving transmission control protocol (TCP) uplink performance of a wireless user equipment (UE) device which multiplexes radio resources between multiple radio access technologies (RATs). Radio control may be provided to a radio resource control (RRC) entity that operates according to a first RAT at a first time. The first RAT may utilize TCP packet-switched (PS) communications. As a second time, radio control may be provided to an RRC entity that operates according to a second RAT which utilizes circuit-switched communications in order to check for paging messages. Radio control by the first RAT's RRC entity may be suspended while radio control is provided to the second RAT's RRC entity. An indication that radio control by the first RAT's RRC entity is suspended may be provided to a TCP entity that operates according to the first RAT. The TCP entity may suspend an uplink retransmission timer in response to the indication.
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:
Methods, apparatuses and computer readable media are described that adjust connection states between a mobile wireless device and a wireless network upon detection of a connection state synchronization failure. After an interruption of a connection between the mobile wireless device and the wireless network, the mobile wireless device responds to a paging message received from the wireless network to establish a new radio resource control (RRC) connection or to re-establish an RRC connection with the wireless network, when an internal state of the mobile wireless device an at least a portion of contents of the paging message indicate the connection state synchronization failure.
Abstract:
Methods and apparatus for the automated altering of wireless device states in response to detected connection behaviors. In one embodiment, a mobile device receives network parameters, some of which are incorrectly configured, from a base station (or access point). To ensure the proper behavior of the mobile device, the device reviews the network provided parameters to determine if one or more of the parameters has been set incorrectly. If so, the device locally alters its own settings to mitigate the incorrect operation associated with the incorrect network provided parameters. In second exemplary embodiment, a number of tolerances are utilized to ensure the proper operation of the mobile device while maintaining an active link. Upon violation of one or more of these tolerances, the device breaks the active link to the wireless network.
Abstract:
Methods to control reconfiguration of multiple radio access bearers in a mobile wireless device connected to a wireless network are described. The mobile wireless device is connected to the wireless network through a voice connection and a data connection simultaneously. The data connection is concurrently active with the voice connection. Transmission of one or more signaling messages for the data connection is delayed until the voice connection terminates. Representative signaling messages include messages that reconfigure a radio access bearer supporting the data connection and messages estimated to exceed a pre-determined transmission time interval.
