  • Patent number: 9357506
    Abstract: Methods and apparatuses to select a transmit antenna in a mobile wireless device connected to a wireless network are described. The mobile wireless device monitors received signal characteristics through first and second antennas and switches antennas based on the monitored signal characteristics and on an assessment of the sufficiency of available transmit power headroom to accommodate data transmissions in the uplink direction. Sufficiency is determined based on one or more criteria including achievable data rate throughput, quality of service, grade of service, an amount of data buffered, an amount of resources allocated by the wireless network and a number of “power up” commands received by the mobile wireless device during a pre-determined time interval.

  • Patent number: 9288720
    Abstract: Apparatus and methods of performing a network cell reselection for a mobile device after a handover attempt fails. Initially, a handover is attempted for the mobile device in a radio resource control (RRC) connected mode from a serving network base station to a target network base station. Next a failure condition associated with the handover attempt is identified by the mobile device. In one scenario, the failure condition is identified in response to the mobile device receiving an RRC connection release message from its serving network base station. In another scenario, the failure condition is identified when the mobile device detects a radio link failure event. Thereafter, the mobile device performs a network scan to identify any available network base stations for the network cell reselection. Subsequently, the mobile device attaches to a preferred network base station of the identified available network base stations to complete the network cell reselection.

  • Publication number: 20150245368
    Abstract: Transmission capacity for a control channel sent to multiple mobile wireless devices in a wireless network is increased by transmitting the control channel using multi user multiple input multiple output transmissions (MU MIMO). Received signal quality measured at mobile wireless devices in a radio sector are communicated to a radio node and used to determine one or more sets of mobile wireless devices to share transmission of control channel elements on the same time and frequency resource element. The radio node indicates the use of MU MIMO and the selection of precoding matrices to each of the mobile wireless devices in the each set of mobile wireless devices.

  • Patent number: 8909215
    Abstract: A method to control measurement messaging is performed at a mobile wireless device. The mobile wireless device transmits a first measurement message to a radio access network in a wireless network and stores the first measurement message pending receipt of an acknowledgement from the radio access network. Before receiving the acknowledgement to the first measurement message, the mobile wireless device determines at least one parameter included in the first measurement message requires updating. The mobile wireless device deletes the stored pending first measurement message and transmits a second measurement message to the radio access network including an updated value for the at least one parameter in the first measurement message.

  • Patent number: 8761701
    Abstract: Method, apparatus and computer program product measuring signals received through multiple antennas in a mobile wireless device is described. Signals received through at least one of a primary antenna and a secondary antenna, during each cycle in a series of discontinuous reception cycles, is measured. The mobile wireless device switches between the primary and secondary antennas based on comparing the moving averages of the measured received signals to pre-determined thresholds. When unable to decode successfully a signal received on the primary antenna, the mobile wireless device switches to decode signals received on the secondary antenna.

  • Patent number: 8705448
    Abstract: Controlling non-simultaneous voice and data connections between a mobile wireless device and a wireless network is described. Following a voice connection origination failure between the mobile wireless device and the wireless network, the mobile wireless device sends a voice connection redial request only after closing an existing data connection between the mobile wireless device and the wireless network. The mobile wireless device tunes a wireless transceiver to a second voice connection channel radio frequency that differs from a first data connection channel radio frequency and establishes a voice connection with the wireless network on the second voice connection channel radio frequency.

  • Patent number: 8504013
    Abstract: Managing radio resources between a mobile device and a wireless network includes at least the following. An application processor in the mobile device classifies radio resources available into at least two distinct sets, a first set of active connections and a second set of potential connections. The application processor forms a measurement message that includes information about the measured radio resources and communicates the measurement message to a wireless network through a transceiver. Before receiving an acknowledgement of the measurement message from a radio network subsystem in the wireless network, the application processor determines at least one parameter included in the measurement message requires updating. The transceiver stops transmitting the measurement message in response to commands from the application processor.
