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.

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.

An embodiment of methods and user equipment are disclosed. Once such method includes a user equipment transmitting preferences for Flow-to-RAT mapping to a base station of a network. The user equipment may receive a Flow-to-RAT mapping from the base station that specifies a particular RAT to be associated with a particular Flow.

Systems and techniques for traffic splitting based on latency between cells are herein described. At an eNodeB, a transmission path latency for a portion of a transmission path between the eNodeB and a user equipment (UE) may be measured via a secondary eNodeB when the UE is dually connected to both the eNodeB and the secondary eNodeB. The transmission path latency may be compared to a threshold. A layer in a transmission stack to split traffic to the UE may be determined based on the comparison of the transmission path latency to the threshold, the traffic being split between the eNodeB and the secondary eNodeB.

Technology for reducing coexistence interference in a multi-radio device is disclosed. One method comprises applying discontinuous reception (DRX) to a user equipment (UE) having a plurality of radio transceivers. The DRX can include a long DRX cycle for the UE. One of a 2 milliseconds (ms), 5 ms, and 8 ms cycle start offset period may be provided for the long DRX cycle to reduce coexistence interference between the plurality of radio transceivers in the UE. The cycle start offset period is selected to provide at least one Hybrid Automatic Repeat Request (HARQ) process reservation pattern to reduce the coexistence interference between the plurality of radio transceivers in the UE.

Technology for communicating user equipment (UE) power consumption configurations is disclosed. One method can include selecting, at the UE, a Power Preference Indication (PPI) state of a power consumption configuration of the UE. The UE can receive, from a source evolved node B (eNB), instructions to begin a PPI Prohibit Event Interval during a handover from the source eNB to a target eNB, wherein the UE cannot send the PPI state to the source eNB during the PPI Prohibit Event Interval. The UE can send the PPI state to the target eNB after the PPI Prohibit Event Interval ends and handover has either successfully completed or failed from the source eNB to the target eNB.

Technology for communicating a discontinuous reception (DRX) reconfiguration is disclosed. In one method, a preferred power consumption configuration message is received, at an evolved node B (eNB) from a user equipment. The preferred power consumption configuration message may be a one-bit message using a first Boolean value to indicate a preferred power consumption configuration. A DRX reconfiguration request message may be received, from the UE, to reconfigure a DRX configuration of the UE to reduce a power consumption level of the UE. The DRX reconfiguration request message may be the one-bit message using a second Boolean value to indicate a DRX reconfiguration. The eNB may determine to reconfigure the DRX configuration of the UE based on the DRX reconfiguration request message. In addition, the eNB may perform the DRX reconfiguration at the UE by adjusting one or more parameters of the DRX configuration.

摘要:
In typical UEs, scanning for WiFi access points (APs) can consume a significant amount of power. This scanning occurs when the UE is connected through the cellular network, but does not occur when the UE is connected to a WiFi network. As a result, offloading a UE from a cellular network to a WiFi network can allow the UE to conserve power. An issue with existing cellular networks is that the UE cannot inform a cellular network that the UE is running low on power, and therefore cannot direct the cellular network to offload the UE for power conservation reasons. A technique discussed herein allows the UE to indicate its power saving needs to the cellular network. In response, the cellular network can lower (or raise) a particular threshold, so that the UE now exceeds (or no longer exceeds) the threshold, and initiates offloading.
