  • Patent number: 11477664
    Abstract: Methods, systems, and devices for wireless communications are described. The method, systems, and devices may include techniques for establishing a first connection with a first cell operating in accordance with a first radio access technology (RAT), and performing a beam sweep procedure for one or more candidate beams for adding or handover to a second cell operating in accordance with millimeter wave (mmW) RAT. The beam sweep procedure may be performed based on previous beam measurements stored in a measurement database. The techniques may further include selecting a beam from the one or more candidate beams for adding or handover to the second cell based on the beam sweep procedure, and adding or handing over to the second cell by establishing a second connection with the second cell using the selected beam.

  • Patent number: 11265068
    Abstract: Methods, systems, and devices for wireless communications are described. An example method includes performing transmission or receive beam measurements at two or more wireless antennas of a wireless device, selecting a serving beam pair based at least in part on the transmission or receive beam measurements, and presenting an indication at the wireless device corresponding to the selected serving beam pair. The method may further include detecting user obstruction of part of the selected serving beam pair. The method may also include determining that a transmission power restriction applies to a first antenna associated with the selected transmission beam based at least in part on the transmission or receive beam measurements. Other example methods may further include detecting a change in an orientation of the wireless device and performing the transmission or receive beam measurements in response to detecting the change in the orientation of the wireless device.

  • Patent number: 10998956
    Abstract: 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.

  • Patent number: 9049650
    Abstract: 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.
