Abstract:
Discontinuous reception (DRX) alignment techniques for dual-connectivity architectures are described. In one embodiment, for example, user equipment (UE) may comprise one or more radio frequency (RF) transceivers, one or more RF antennas, and logic, at least a portion of which is in hardware, the logic to receive a radio resource control (RRC) configuration information message containing a small cell RRC configuration information element (IE), the small cell RRC configuration IE to contain a small cell discontinuous reception (DRX) configuration IE comprising one or more inter-cell-coordinated small cell DRX parameters, the logic to determine a start time for a small cell DRX cycle based on at least one of the one or more inter-cell-coordinated small cell DRX parameters and initiate the small cell DRX cycle at the determined start time. Other embodiments are described and claimed.
Abstract:
A user equipment (UE) includes a transmission mode component, a selection component, and a transmission component. The transmission mode component is configured to selectively allocate resources for device-to-device communication according to a plurality of transmission modes. The plurality of transmission modes include a first transmission mode in which the resources used by the UE are specifically allocated by one of a base station or relay node and a second transmission mode in which the UE selects the resources from a pool of available resources. The selection component is configured to select a selected transmission mode. The transmission component is configured to transmit signals in frequency resources selected according to the selected transmission mode.
Abstract:
Systems, apparatus, user equipment (UE), evolved node B (eNB), and methods are described for generating an extended power headroom report (ePHR) based on an uncertainty associated with a physical downlink control channel communication granting an uplink grant for a physical uplink shared channel communication when the system is configured for simultaneous physical uplink shared channel and physical uplink control channel communications. Some embodiments are structured to generate the ePHR using a type 2 report regardless of the uncertainty associated with the ePHR, while other embodiments generate the ePHR using a reference format. In some embodiments, a UE communicates a timing field with a UE capability communication indicating whether the UE meets timing requirements to avoid uncertainty in ePHR communications.
Abstract:
In an embodiment, an apparatus to be employed in a user equipment (UE) is described. The apparatus includes configuration circuitry operable to determine, based on one or more configuration information messages, a measurement gap for a master evolved Node B (MeNB) that is operable to provide a master cell group (MCG) that is asynchronous with a secondary cell group (SCG) of a secondary evolved Node B (SeNB), wherein subframe boundaries of the MCG are different from subframe boundaries of the SCG; and radio frequency (RF) control circuitry operable to cause RF circuitry to be tuned, at a beginning of the measurement gap based on a subframe boundary of the MCG, to start inter-frequency measurements, wherein the RF circuitry is to be used to transmit or receive data in a serving cell of the MCG and in a serving cell of the SCG. Other embodiments are also described and claimed.
Abstract:
Embodiments of a User Equipment (UE) to support inter-frequency handover are disclosed herein. The UE may receive, from an Evolved Node-B (eNB), a measurement report configuration message that includes multiple measurement events to be determined at the UE. The UE may transmit a measurement report when a combined measurement event occurs. The combined measurement event may include a combination of the multiple measurement events according to a "logical AND" operator such that the combined measurement event occurs when the multiple measurement events occur. The measurement events may be related to signal measurements performed on one or more signals received at the UE from one or more cells configured for operation in the network.
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 connected mode on respective wireless cells provided by first and second eNBs. The UE may be adapted to estimate respective power headroom (“PHR”) values associated with simultaneous operation on the first and second wireless cells. The UE may cause the first and second PHR estimates to be transmitted to both the first and second eNBs. The first and second eNBs may use these estimates to compute respective uplink transmission powers for the UE. Other embodiments may be described and/or claimed.
Abstract:
Embodiments of user equipment (UE), an enhanced node B (eNB), and methods of signaling for proximity services and device-to-device (D2D) discovery in an LTE network are generally described herein. In some embodiments, the UE receives configuration information for a D2D discovery resource pool of a cell. The configuration information includes an indication that the D2D discovery resource pool has been logically divided into a plurality of sub-discovery resource pools. The UE performs an initial transmission of a discovery signal in a discovery period using a single D2D discovery resource from a first sub-discovery resource pool of the plurality of sub-discovery resource pools. The UE performs a number of additional transmissions of the discovery signal in the discovery period using additional D2D discovery resources from sub-discovery resource pools of the plurality of sub-discovery resource pools other than the first sub-discovery resource pool. Other apparatuses and methods are also described.
