    Abstract: This disclosure relates to techniques for efficient sparse network resource usage and connection release procedures. According to some embodiments, a wireless device may utilize techniques for efficiently releasing a radio resource control (RRC) connection, including techniques that avoid or reduce the occurrence of random access procedures when out-of-sync with the network when the RRC connection is being released. In some embodiments, a wireless device may utilize techniques for efficiently sparsely using network uplink resources, including techniques that avoid or reduce the occurrence of random access procedures to regain timing alignment to perform uplink communication when out-of-sync with the network.

    Abstract: A system, devices and methods for providing input from a user equipment (UE) for the selection of a carrier channel combination for use in carrier aggregation. The exemplary system includes a UE configured to perform carrier aggregation, the UE storing a radio frequency (RF) calibration table including a plurality of transmission related requirements specific to the UE, the UE configured to generate priority data for each carrier channel combination supported for use in carrier aggregation based upon the RF calibration table and a network component receiving the priority data and an indication from the UE, the network component configured to select a carrier channel combination for use in carrier aggregation based upon the priority data, the network component transmitting carrier aggregation configuration data including the selected carrier channel combination to the UE.

    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.

    Abstract: This disclosure relates to techniques for using wireless link information from baseband to trigger application data activity. According to some embodiments, wireless link information from baseband may be received at an application processor of a wireless device. The wireless link information may indicate whether the wireless link is in a connected state or an idle state. Network activity timing for one or more application network activity requests may be selected based at least in part on the wireless link information. The application network activity may be initiated for the one or more application network activity requests according to the selected network activity timing.
