  • Patent number: 10484894
    Abstract: System and methods for providing special radio provisions to link budget limited devices. Before establishing a cellular connection with a cellular network, a user equipment device (UE), such as a link budget limited UE, may negotiate the special radio provisions with the network by presenting requested profile information to the network, and receiving back approved profile information from the network. The UE may perform these communications either directly, via a non-cellular communication connection with the network, or indirectly, via a companion or proxy device. When the UE initiates a cellular connection with the network, both entities may use information specified in the approved profile information, which may improve efficiency of the connection. In some scenarios, the approved profile information may identify a class of devices to which the UE belongs. The approved profile information may also be used in establishing connections with other devices of the same class.

  • Patent number: 10412780
    Abstract: Method and apparatus of a user equipment (UE) device communicating during discontinuous reception (DRX). The UE may determine a data traffic pattern of an application executing on the UE. The UE may compare the data traffic pattern against a plurality of DRX configuration settings of a base station (BS). The UE may determine that the DRX configuration settings do not match the data traffic pattern. The UE may select a first DRX configuration setting based on the data traffic pattern. The UE may perform communication according to the first DRX configuration settings. The UE may transmit a scheduling request (SR) outside of a DRX on-duration according to the data traffic pattern. Transmitting the SR may be based on the DRX configuration settings not matching the data traffic pattern of the application. In response to transmitting the SR, the UE may receive downlink data of the application from the BS.

  • Patent number: 10334599
    Abstract: A device and method for transmitting user equipment capability information to a network. In a first mechanism, the device and method determines the carrier aggregation (CA) combinations supported by the user equipment that are relevant to the user equipment. in a priority order to the network. The relevant CA combinations may be determined based on most recent camped bands and the neighbor bands of the most recent camped bands. In a second mechanism, the device and method orders the relevant CA combinations into a prioritized list according to which CA combination have priority based on selected priority factors. Subsequently, the user equipment broadcasts the prioritized list of CA combinations to the network.

  • Patent number: 10230808
    Abstract: This disclosure relates to techniques for UEs to improve reception of push notifications via a cellular network. A UE may be configured to provide, to a push notification service, preference information for push notifications associated with an application. The preference information may indicate a preferred period of delivery for the push notifications. When the push notification service receives a push notification addressed to the UE, the push notification service includes the preference information when notifying the cellular network. The cellular network provides a page to the UE, including the preference information. Based on the preference information in the page, the UE may decide whether, and in some scenarios how long, to delay before establishing a connection to receive the available push notification. The network, having access to the preference information, may accommodate the delay.
