Patent number: 9357506Abstract: 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.Type: GrantFiled: September 8, 2014Date of Patent: May 31, 2016Assignee: Apple Inc.Inventors: Gaurav R.

Patent number: 9288720Abstract: 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.Type: GrantFiled: October 8, 2013Date of Patent: March 15, 2016Assignee: Apple Inc.Inventors: Gaurav R.

Patent number: 8504013Abstract: 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.Type: GrantFiled: January 7, 2011Date of Patent: August 6, 2013Assignee: Apple Inc.Inventors: Prashant H.
