Patent number: 10998956Abstract: Aspects of the disclosure relate to minimizing the number of antenna array modules on a wireless communication device utilized in forming beam pair links (BPLs) based on beam measurements obtained on each of a plurality of receive beams for each of a plurality of transmit beams. For at least one BPL, the wireless communication device selects a different receive beam that results in at least one fewer active antenna array module. In some examples, the different receive beam selected for a BPL has a beam measurement value within a predefined variance from a beam measurement value of an original receive beam for the BPL. In addition, the wireless communication device can confirm that the beam measurement values of both the original and different receive beams satisfy a minimum beam measurement value before switching the BPL to the different receive beam. Other aspects, features, and embodiments are also claimed and described.Type: GrantFiled: June 30, 2020Date of Patent: May 4, 2021Assignee: Qualcomm IncorporatedInventors: Arnab Pal, Vishnu Namboodiri Karakkad Kesavan Namboodiri, Mahendran Kamatchi, Nagaraju Gajula

Patent number: 9049650Abstract: Methods and apparatus for selecting an inter-radio access technology for an electronic device are disclosed. In an embodiment, a wireless electronic device determines if a first radio signal strength (e.g., LTE) is weak enough that the device should start scanning for another radio access technology (e.g., CDMA). If the first radio signal strength (e.g., LTE) is very weak (e.g., even weaker than the level that caused the device to start scanning), and a second radio signal strength (e.g., CDMA) is above a second threshold, then the device selects the second radio access technology (e.g., switches from LTE to CDMA). If (a) the first radio signal strength (e.g., LTE) is not weak enough to warrant a move to another radio access technology, (b) the second radio signal strength (e.g., CDMA) is not above the second threshold (e.g., not strong enough to warrant a move), and/or (c) a motion sensor determines that the device is relatively stationary (e.g.Type: GrantFiled: December 7, 2012Date of Patent: June 2, 2015Assignee: Google Technology Holdings LLCInventors: Nagaraju Gajula, Frank D Ciotti
