Abstract: A cellular wakeup receiver (C-WuRx) for reducing power consumption of a wireless wide area network (WWAN) radio of a user equipment (UE) includes receiver circuitry to receive a wakeup signal from a base station in response to the UE performing link aggregation by which downlink communications from the base station are offloaded to a wireless local area network (WLAN). The C-WuRx also includes processing circuitry to configure the receiver circuitry to periodically monitor at least a portion of a WWAN band for the wakeup signal and process the wakeup signal to cause the WWAN radio to resume receiving the downlink communications from the base station.

Abstract: Embodiments of the present disclosure describe systems and methods for partitioning radio frequency spectrum for multiple categories of communication. Various embodiments may include partitioning of an available frequency band into a first partition for a first category of communication and a second partition for a second category of communication. In embodiments, the first category of communication may be designed for devices having a relatively lower cost of implementation than the second category of communication. In some embodiments, the first partition may be aggregated opportunistically with the second partition based on certain conditions such as, for example, under utilization of the first partition. Other embodiments may be described and/or claimed.

Abstract: Briefly, in accordance with one or more embodiments, a fixed device synchronizes with a downlink channel of a network, acquires a master information block including a last system update time; and executes cell selection without acquiring other system information if the last system update time is before the last system access time. Furthermore, the fixed device may listen only for system information block messages that it needs, and ignore other system information blocks. A bitmap may indicate which system information block messages should be listed to for fixed devices, and which may be ignored. In some embodiments, one or more system information blocks may be designated for fixed devices.

Abstract: An apparatus and method for initiating discontinuous reception (DRX) operation in a user equipment (UE) are disclosed herein. Applications running on the UE are monitored by the UE to identify one or more inactivity trigger events associated with the application(s). The UE includes an application-radio cross layer to process the application information, including the inactivity trigger event, for use by a radio layer. The radio layer of the UE determines initiation of the DRX operation in accordance with the application information, including the inactivity trigger event, provided by the application-radio cross layer and device characteristics information.

Abstract: Technology is discussed for reducing the frequency of signaling overhead and power consumption on wireless mobile devices employed to support internet applications in a Wireless Wide Area Network (WWAN). Demands for battery power and signaling overhead frequently arise to support background messages of little significance and/or urgency when internet applications are unattended on wireless mobile device attempting to conserve power. An identification module can be triggered to identify such background messages, based on a variety of factors. The identification module can also determine whether to buffer and/or drop such messages with information local to the wireless mobile devices and/or in such background messages. Such buffering and dropping measures can reduce the frequency with which wireless mobile devices consume large amounts of power and/or require signaling overhead to send and receive these background messages.

Abstract: Briefly, in accordance with one or more embodiments, a fixed device synchronizes with a downlink channel of a network, acquires a master information block including a last system update time; and executes cell selection without acquiring other system information if the last system update time is before the last system access time. Furthermore, the fixed device may listen only for system information block messages that it needs, and ignore other system information blocks. A bitmap may indicate which system information block messages should be listed to for fixed devices, and which may be ignored. In some embodiments, one or more system information blocks may be designated for fixed devices.
