  • Apparatus, systems and methods for an adaptive segment size for data transmissions
    Patent number: 10433213
    Abstract: Described herein are apparatus, systems and methods for adaptive segment size for data transmissions. A method may comprise, at a user equipment (“UE”), identifying a current size setting of a data segment (e.g., a transmission control protocol (“TCP”) maximum segment size (“MSS”)) for communication over a network, receiving current physical layer conditions, receiving historical data, and adjusting the current size setting based on at least one of the current physical layer conditions and the historical data.

  • Device, system, and method for carrier aware scheduling
    Patent number: 10334611
    Abstract: Described is a user equipment (UE) that is connected to a network component, the user equipment and the network component configured with a carrier aggregation functionality. The UE performs a method that includes determining a primary component carrier and at least one secondary component carrier associated with the carrier aggregation functionality of the user equipment, determining a component carrier quality measurement (CQM) metric for each of the component carriers, when an uplink data packet is capable of being transmitted over the secondary component carrier, selecting one of the primary component carrier and the at least one secondary component carrier based on the CQM metrics, generating measurement data indicative of the selected component carrier to increase a probability to transmit the uplink data packet over the selected component carrier and transmitting the measurement data to the network component.

  • Cell utilization estimation by a wireless device
    Patent number: 9179355
    Abstract: Estimating loading and potential available throughput a serving cell of a wireless user equipment (UE) device. Physical layer metrics of a channel on which the UE communicates with the serving cell may be measured. Cell utilization of the serving cell may be calculated based at least in part on the measured physical layer metrics. A maximum available throughput of the serving cell may be calculated based on the cell utilization.
