Abstract: Embodiments disclosed herein relate to devices and methods that provide adaptive CRE-based offset parameters that take into account the speed of a UE and that take into account the DL/UL traffic balance being experienced by the UE. For example, if the speed of a UE is greater than the predefined speed, the UE utilizes an adaptive CRE-based offset parameter that has a low value or is equal to zero. Similarly, if the balance of downlink/uplink traffic being experienced by a UE is mainly downlink traffic, the UE utilizes an adaptive CRE-based offset parameter that has a low value or is equal to zero. Consequently, the embodiments disclosed herein reduce the handover failure associated with CRE particularly for high speed UEs while also being able to increase downlink system capacity if the balance of the downlink and uplink traffic experienced by the UE is mostly downlink traffic.

Abstract: Technology for efficiently splitting a bearer at the packet data convergence protocol (PDCP) layer for uplink (UL) data transfers in wireless networks where dual connectivity is available is disclosed. A user equipment (UE) can send buffer status reports (BSRs) to a master evolved node B (MeNB) and a secondary evolved node B (SeNB). The BSRs can be formatted such that the amount of data in a radio link control (RLC) buffer at the UE and the amount of data in a packet data convergence protocol (PDCP) buffer at the UE are contained in different fields. The BSRs can also contain redundancy indicator (RI) values specifying a redundancy level between the PDCP buffer amounts included in the BSRS. The MeNB and the SeNB may then coordinate, via an X2 interface, an amount of uplink (UL) resources to allocate to the UE.

Other embodiments are described and claimed.

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: Embodiments described herein relate generally to a communication between a user equipment (“UE”) and a plurality of evolved Node Bs (“eNBs”). A UE may be adapted to operate in a dual connectivity mode on respective wireless cells provided by first and second eNBs. The UE may communicate with a first eNB in a first frequency band. The UE may communicate with a second eNB in a second frequency band. The first eNB may detect that the second frequency band is unavailable. Based on this detection, the first eNB may notify the UE that communication in the second frequency band is no longer available. In response, the UE may control a radio to cease communication in the second frequency band. Other embodiments may be described and/or claimed.

Abstract: 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.

Other embodiments may be described and/or claimed.

Abstract: Systems and methods are disclosed for communicating enhanced user equipment (UE) assistance information between nodes in wireless communication systems.

Abstract: Technology for a target evolved node B (eNB) operable to facilitate handover is disclosed. The target eNB can receive a handover request message to hand over a user equipment (UE) from the source eNB to the target eNB. The handover request message can include an evolved packet system (EPS) bearer group identifier (ID) indicating an EPS group bearer of the source eNB and associated with the UE, a last UE indicator to indicate whether the UE is a last UE of the source eNB to use the EPS group bearer, and a downlink (DL) traffic indicator to indicate whether the DL traffic for the UE during handover is negligible. The target eNB can perform a handover procedure to establish a connection with the UE based on at least one of the EPS bearer group ID, the last UE indicator, or the DL traffic indicator included in the handover request message.

In one embodiment, for example, user equipment (UE) may comprise logic, at least a portion of which is in hardware, the logic to receive a radio resource control (RRC) configuration message during operation in a dually-connected UE state, determine whether UE assistance information reporting is enabled for the UE based on the RRC configuration message, and in response to a determination that UE assistance information reporting is enabled for the UE, send one or more UE assistance information messages to report a macro cell power preference and a small cell power preference. Other embodiments are described and claimed.

Abstract: In accordance with some embodiments, a new discontinuous reception (DRX) parameter change may be received in user equipment while the user equipment is using an existing DRX parameter. The user equipment continues to use the existing parameter and determines when a new discontinuous reception cycle is starting. The change to the next discontinuous reception parameter is implemented in the new discontinuous reception cycle. In some embodiments by having an agreed upon time to implement the change to the new parameter, signaling between an enhanced node B and user equipment may be reduced. Signaling overhead is a serious impediment to achieving high efficiency in wireless communications.
