    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.

    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.

    Abstract: Apparatus and methods for estimating data traffic characteristics for applications to condition data communication channels that support data packet transfer for the applications in wireless communication devices are disclosed. Data connections to support different applications and/or daemon software processes can be established and subsequently adjusted based on data traffic characteristics for data that the different applications/daemons generate and/or consume. Traffic flows for the applications/daemons are classified into traffic classes based on likely data traffic patterns. When data sources are added or deleted, changes to a traffic class state can be determined, and wireless circuitry adjusted based at least in part on the traffic class state and a traffic class policy. Adjusting parameters that affect the periodicity and/or length of active time periods and sleep periods in accordance with estimated data traffic patterns for applications/daemons that use the data connections can reduce power consumption by the wireless circuitry.

    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.
