    Abstract: A user of a device desires that geographic position information of the device be kept private. A network may track a geographic position of a device using timing advance (TA) data and also a passive attacker may attempt to track the geographic position of the device by observing base station TA commands. In embodiments provided herein, a device diminishes or obfuscates geographic position information by using a timing change value while not disturbing synchronization of uplink signals from multiple devices arriving at a base station. To resist an averaging solution by an observer, the device in some embodiments adjusts the timing change value based on an internal timer. In an emergency call situation, the method permits the base station to obtain geographic position information based on TA procedures.

    Abstract: An enhanced listen-before-talk procedure may be performed by a device for efficiently accessing and utilizing available resources. The procedure may include specifying input parameter values pertaining to intended wireless communications of the device, adjusting output parameter values based on the input parameter values and an access history of the device, and determining whether to access at least a portion of the wireless communication resources to conduct the wireless communications, based at least on the output parameter values. The output parameter values may pertain to wireless communication resources accessible to the device, and the access history may keep track of wireless communication resource accesses previously made by the device. Input parameter values may include requested channel occupation time, requested frequency resource, requested transmission power, and/or priority and/or urgency of requested transmission, while output parameter values may include energy detection threshold, contention window size, and/or extended clear channel assessment bypass.

    Abstract: This disclosure relates to techniques for estimating baseband power consumption and using the baseband power consumption estimation to select baseband operation features. According to some embodiments, one or more baseband power consumption modifiers occurring during an estimation window may be identified. Baseband power consumption of the wireless device during the estimation window may be estimated based on the identified baseband power consumption modifiers occurring during the estimation window. Baseband data throughput of the wireless device during the estimation window may also be estimated. One or more baseband operation characteristics may be selected based at least in part on the estimated baseband power consumption during the estimation window, possibly in conjunction with the estimated baseband data throughput during the estimation window, current wireless medium conditions, and/or other considerations.

    Abstract: Apparatuses, systems, and methods for a wireless device to perform a method including a user equipment device (UE) exchanging communications with a base station to determine one or more scheduling profiles, such as one or more scheduling-power profiles, where a scheduling-power profile may specify one or more parameters associated with UE communication behavior, e.g., one or more constraints on UE communication behavior and/or slot scheduling of UE communications. In addition, the method may include the UE receiving a slot configuration schedule from the base station. The slot configuration schedule may be based on at least one scheduling-power profile of the one or more scheduling-power profiles. Further, the method may include the UE performing communications with the base station based on the at least one scheduling-power profile.
