Abstract:
An apparatus for use in a remote UE of a ProSe network comprising a relay UE and an eNodeB associated therewith, comprising a processing circuit configured to generate a connection request message for subsequent transmission to the relay UE, over a PC5 interface between the remote UE and the relay UE, to setup an initial connection with the relay UE. The processing circuit is further configured to receive a connection setup message comprising resource configuration parameters of the remote UE, from the relay UE over the PC5 interface, in order to configure the resources of the remote UE. In addition, the processing circuit is configured to provide a connection setup complete message to the relay UE with indication for performing a service request in order to establish EPS bearers of the remote UE in the network to enable Layer 2 relaying.
Abstract:
A User Equipment (UE) device operates to directly determine a target small cell for access or handover with the assistance of a macro cell network. The UE directly generates the connection and selects which small cell to access from among a subset of small cells chosen of a set of candidate small cells. The UE is provided dedicated assistance information from the evolved node B (eNB) or macro network device. The dedicated assistance information enables the UE to measure data from the candidate small cells within a heterogeneous network environment. The UE shares the measured data and connects directly to the selected small cell for an access or handover operation.
Abstract:
A user equipment (UE) can reserve shared spectrum between two wireless protocols upon the request from a tower. For example, an enhanced node B (eNB or eNodeB) transmits a message to associated UEs including a set of candidate UEs, a length of time to reserve, and a frequency band to use. UEs perform medium sensing on the specified spectrum if a UE finds its identifier in the set of candidate UEs. Candidate UEs transmit a clear to send (CTS) message with channel reservation information if the medium is idle. A result of the success or failure of the CTS transmission attempt is sent back to the eNB. Upon receiving the feedback information from the UEs, the eNB starts sending data to those UEs that sent the positive feedback on the channel reservation.
Abstract:
Techniques for enabling dual-connectivity in LTE systems for terminals with only single uplink component carrier capability are described. Dual connectivity refers to a terminal having serving cells from two base stations. In one technique, the terminal transmits to macro and small cells using time division multiplexing. In another, the terminal transmits to one cell only, either the macro cell or the small cell.

Embodiments of the present disclosure describe methods and apparatuses for mechanisms to provide tracking of user equipment at radio access network level.
Abstract:
Technology for a base station is disclosed. The base station can determine radio access network (RAN)-based UE paging parameters for configuration of a UE when the UE is in a suspended state. UE context information for the UE can be stored in a memory of the base station when the UE is in the suspended state. The base station can encode the RAN-based UE paging parameters for transmission to the UE directly or via a core network (CN) node. The base station can generate a RAN-originated paging message for the UE when downlink data is received at the base station for the UE. The base station can encode the RAN-originated paging message for transmission to the UE. The RAN-originated paging message can be transmitted from the base station and received at the UE in accordance with the RAN-based UE paging parameters.
Abstract:
User equipment (UE) handover (HO) techniques for reducing or eliminating interruption time during an HO process are described. In one embodiment, for example, an apparatus may include at least one memory and logic for an evolved node B (eNB), at least a portion of the logic comprised in hardware coupled to the at least one memory. The logic may be operative to forward downlink (DL) data received from a serving gateway (SGW) to user equipment (UE), transmit a handover command to the UE to trigger execution of a handover (HO) process to handover the UE to a target eNB, continue forwarding at least a portion of the DL data to the UE following transmission of the handover command, and terminate transmission of the DL data to the UE responsive to detecting a stop DL data event. Other embodiments are described and claimed.
Abstract:
The periodic broadcasting of system information by an eNB is costly in terms of both spectrum and energy. Embodiments described herein more efficiently transmit system information and are particularly applicable to 5G deployment scenarios. In one embodiment, an LTE cell broadcasts system information to be used by a UE in initially connecting to a 5G cell, termed initial access system information. The 5G cell may then transmit system information upon request by a connected UE or when the system information is updated.
Abstract:
An uplink (UL) traffic control method is disclosed. The UL traffic control method exploits an available operator-controlled WiFi wireless local area network. The UL traffic control method, operating from within the LTE modem, employs one of three possible techniques for controlling the user equipment (UE) UL traffic within an integrated multiple radio access control (RAT) architecture. The operations are seamless and transparent to a user of the multi-RAT UE.
Abstract:
A user equipment (UE) is configured to perform cell selection and camp on a first cell in a first frequency resource. The UE is configured to determine that proximity services are supported in a second frequency resource. The first and second wireless frequency resources are within licensed spectrums corresponding to one or more mobile communications networks. The UE is configured to start device-to-device communication on the second frequency resource and send, with the transceiver, a device-to-device message in the second frequency resource. The device-to-device message includes one of a device-to-device discovery message and a device-to-device communication message.
