    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: Various mechanisms for paging link-budget-limited (LBL) devices are disclosed, including: (1) transmitting paging message with non-conventional paging identifier; (2) transmitting paging message(s) with increased power; (3) repeating transmission of paging message to support combining at receiver. Various mechanisms for UE device to signal LBL status are disclosed, including, transmitting status flag or special value of DRX cycle to network node as part of tracking area update and/or attach request. The network node informs a base station of the device's LBL status as part of a paging message. (The network node may, e.g., assign an S-RNTI to the LBL device from a reserved subset of S-RNTI space.) The base station invokes a paging enhancement mechanism when paging an LBL device. Alternatively, the base station may page UE devices without knowledge of LBL status, e.g., by counting paging attempts for a given UE, and boosting power after the Nth paging attempt.

    Abstract: Methods related to an inactive state of a user equipment (UE). In one example, when an amount of data in an uplink buffer is less than a threshold, the data is sent to the network while remaining in the inactive state. In another example, when reselecting to a different cell, the UE attempts to reselect to the different cell and remain in the inactive state. When transitioning to a connected state at the reselected cell, the UE sends a resume request including an identification of the first cell. In another example, when a high priority or a background PLMN search is performed in the inactive state, the results are cached and implemented the earlier of when a timer expires or the UE enters an idle state. In another example, a cell reselection criteria is altered in the inactive state to make it less likely that a cell reselection will occur.

    Abstract: This disclosure relates to techniques for performing ranging wireless communication including prioritization. A first wireless device may transmit a request for ranging services to a second wireless device. The first wireless device may transmit an indication of a ranging priority to the second wireless device. The second wireless device may determine a granted ranging priority. The first and second wireless device may perform ranging communication according to the granted ranging priority.
