Abstract: An enhanced paging mechanism is provided for UEs waking up from a very long paging cycle to improve paging robustness and flexibility. Enhanced paging includes absolute time paging (ATP) and paging with extended wakeup time. For absolute time paging, a UE receives ATP configuration and uses the actual wall time to calculate paging occasion if a condition is satisfied. In one embodiment, the wall time is acquired from at least one of an internal UE clock, a GPS time, information broadcasted from the network, or information from a higher layer signaling. For paging with extended wakeup time, a UE applies a long paging cycle followed by multiple normal paging cycles after waking up from the long paging cycle. In one embodiment, the long paging cycle is infinite and the UE enters normal paging cycle only upon TAU-triggered paging or uplink traffic.

The collected information may include outputs from one or more sensors, such as an accelerometer, a microphone, a camera, or a biometric sensor. A button press initiating a call may be considered in the context of other usage of the device to estimate whether the call was intentional or unintentional.

Abstract: A method and network node of a radio network, for enabling a User Equipment (UE) to save power in radio communication with the network node. The network node sets a waiting threshold for the UE and communicates data with the UE over a radio link. The network node also obtains traffic characteristics pertaining to the radio communication, and predicts a waiting time until next data is to be communicated with the UE based on the traffic characteristics. The network node further triggers the UE to enter a Discontinuous Reception (DRX) sleep when the predicted waiting time is longer than the waiting threshold. Thereby, power can be saved in the UE by immediately going to sleep after the last data.

Entry or exit may be delayed until after the confirmation signal is received. The confirmation signal may vary depending on the handshaking configuration and activation data, and the confirmation signal may vary depending on whether the wireless device is in a power save mode or not.

Abstract: A system and methodology that performs data bundling and controls fast dormancy based on application monitoring and classification is provided. Moreover, the system provides a balance between saving battery power of a user equipment (UE) and reducing signaling and processing load in a radio resource controller (RRC). Specifically, the system observes data flow related behavior of applications on the UE. On receiving a first data flow request, an arrival time of a next data flow request is predicted based on an analysis of the behavior, and the system determines whether the two data flows can be bundled together and transmitted over a single connection. Additionally, on completion of the first data flow, the arrival time of the next data flow request is predicted based on the analysis, and the system determines whether a fast dormancy timer can be disabled to transmit the next data flow over the current connection.

Abstract: In an example, there is disclosed herein a digital-to-analog converter (DAC) including a correction circuit for a clock, including a differential clock.

The feedback signal may be operable to correct errors, for example, in duty cycle and crosspoint, as measured at the DAC core.

Abstract: A method and system for managing broadcast of notifications indicating whether system information has changed, so as to enable served devices to determine when to read and store updated system information. A radio access network tracks changes in system information on a per wakeup cycle basis, so as to determine whether system information has changed since a last instance of broadcasting such a notification in a particular wakeup cycle. If system information has changed, the network responsively broadcasts an indication that system information has changed, so as to cause devices operating on that wakeup cycle to read and store the updated system information. Whereas, if system information has not changed, the network responsively broadcasts an indication that system information has not changed (or forgoes broadcasting an indication that system information has changed), so that devices operating on that wakeup cycle can avoid reading and storing the system information.

Abstract: A network based positioning (NBP) system is disclosed that allows any of its access points (APs) to initiate ranging operations with a station device (STA), regardless of whether the STA is in power save mode and regardless of whether a particular AP is currently associated with the STA. For example, to initiate ranging operations with the STA from a non-associated AP, the non-associated AP obtains the TSF timer of the associated AP, and then uses the obtained TSF timer to derive the associated AP's beacon transmission schedule and thereby determine when the STA's corresponding wake-up periods occur. Thereafter, the non-associated AP can initiate ranging operations with the STA during the STA wake-up periods, thereby ensuring that probes sent from the non-associated AP will arrive at the STA while the STA is awake from power save mode.
