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.

Cellular wakeup receiver for reducing power consumption of user equipment employing LTE-WLAN aggregation

Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for managing state transitions of communication circuitries in wireless networks. Embodiments manage radio resource control (RRC) state transitions and/or discontinuous reception (DRX) state transitions. Other embodiments may be described and/or claimed.

Communication state transitioning control

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.

System acquisition mechanism for fixed devices in mobile broadband networks

Technology described herein provides systems and technologies that help avoid waste of wireless network resources due to frequent losses of wireless connectivity with energy-harvesting devices (EHDs). An energy-harvesting-indicator communication can be sent from a wireless device to a cellular base station to inform the cellular base station that the wireless device is an EHD. The cellular base station can preserve context information and/or DL data pertaining to a wireless connection with the EHD when a wireless connection is lost due to a temporarily low level of available energy at the EHD. The context information and/or DL data can be preserved by the cellular base station until the period of time elapsed exceeds a threshold time value. Upon receiving a connection-resumption communication from the EHD, the cellular base station can use preserved context information to restore the wireless connection and proceed to send preserved DL data to the EHD.

Outage notification and context preservation for energy-harvesting devices

Embodiments of wireless communication devices and method for discontinuous reception (DRX) mode in wireless communication are generally described herein. Some of these embodiments describe a wireless communication device having processing circuitry arranged to determine to use an extended paging discontinuous reception (DRX) value to increase a paging cycle length above a value and select a first periodicity, based on the extended paging DRX value, at which the UE is to perform evaluation of a parameter of a network in which the UE is opera. The wireless communication device may have physical layer circuitry arranged to transmit a message to the network, indicating that the UE desires to perform evaluation of the parameter at the first periodicity. Other methods and apparatuses are also described.

User equipment and methods for adapting system parameters based on extended paging cycles

Fixed devices may be distinguished from mobile devices in a broadband wireless network. Fixed devices may be given an identifier that identifies the device as a fixed device.

Differentiating fixed devices from mobile devices in mobile broadband networks

Embodiments of an enhanced Node B (eNB) and method to provide system information (SI) updates to user equipment (UE) in sleep or idle mode with an extending paging cycle are generally described herein. In some embodiments, a paging message configured to include an optional field to indicate whether there has been a system information (SI) update since a last paging occasion for a UE in sleep or idle mode with an extending paging cycle. System information updates are transmitted by the eNB during a system information modification period that is shorter than a period the extending paging cycle. The optional field may indicate whether or not the UE is to acquire the latest SI update during the current paging occasion.

Enhanced node B and methods for providing system information updates to user equipment with extended paging cycles

Technology for reducing buffer overflow at a Third Generation Partnership Project (3GPP) Serving Gateway (S-GW) is described. A buffer overflow message may be received, at an evolved node B (eNB) from the S-GW, indicating potential overflow of downlink information at an S-GW buffer. The downlink information may be stored at the S-GW buffer until a plurality of user equipments (UEs) awake from a low power mode during a discontinuous reception (DRX) sleep cycle. One or more UEs may be selected from the plurality of UEs according to predefined criteria, wherein the one or more UEs are in a connected mode. The DRX configurations of the one or more UEs may be modified in order to reduce the downlink information that is stored at the S-GW buffer, thereby reducing the potential for overflow at the S-GW buffer.

Reduction of buffer overflow

Technology for a user equipment (UE) operable to determine a power preference indication (PPI) is described. The UE can determine the PPI as one of a low power consumption or a normal power consumption. The UE can start a PPI timer when the PII is set for the normal power consumption. The UE can encode the PII for transmission to an Evolved Universal Terrestrial Radio Access Network (EUTRAN) in a UE assistance information message.

Communication of preferred power consumption configurations

Methods, systems, and devices for low power consumption in wireless communication systems are disclosed herein. An evolved node B (eNodeB) is configured to provide a connection reconfiguration message to user equipment (UE) connected to the eNodeB, the connection reconfiguration message configuring the UE to indicate a power preference. The eNodeB receives assistance information from the UE. The assistance information includes a low power preference indication and a timer length, wherein the timer length indicates a preferred duration for a low power mode. The eNodeB provides, in response to receiving the assistance information, a connection release message to the UE. The connection release message includes paging discontinuous reception (DRX) information that includes the timer length.

Systems and methods for low power consumption in wireless communication systems

Embodiments of the present disclosure describe systems and methods for operation of an evolved node B to provide multiple coverage enhancement levels. Various embodiments may include an operational mode configured to provide a first coverage enhancement level associated with user equipments (UEs) that have established communication with the eNB. These embodiments may also include a discovery mode configured to operate at a second coverage enhancement level to discover UEs configured for a higher coverage enhancement level. Other embodiments may be described and/or claimed.
