    Abstract: User equipment (UEs) can fallback to a legacy system, such as an evolved packet system (EPS), from a fifth generation system (5GS). For example, a UE camps on the 5GS network by default. When an indicator of a voice call is detected, the UE performs a fallback to EPS for a duration of the voice call. After the voice call, the UE can return to the 5GS. In another example, the UE detects an emergency session request (e.g., internet protocol multimedia subsystem (IMS) emergency session request). The UE performs a fallback to EPS for a duration of the emergency session. After the emergency session is complete, the UE can return to the 5GS. The solution can operate with UEs that operate in either Single Registration (SR) mode embodiments or Dual Registration (DR) mode embodiments. Depending on the embodiment, the UE can perform a handover or redirection to the legacy system (such as E-UTRAN).

    Abstract: User equipment (UE), an enhanced NodeB (eNB) and method of reducing handover latency are generally described. The UE may transmit measurement feedback to the eNB based on control signals. The UE may receive a reconfiguration message from the eNB or another eNB to the UE is attached. The reconfiguration message may contain reconfiguration information indicating whether or not a physical layer or layer 2 of the UE is to be reconfigured and/or a security key is to be updated. The reconfiguration information may be dependent on whether the handover is between eNBs controlled by a same entity and/or whether the handover comprises an intra-frequency transition. The UE or eNB may initiate handover of the UE. During handover the UE may avoid physical layer or layer 2 reconfiguration or the security key update. The security key and data for the UE may be provided directly between the eNBs.

    Abstract: Embodiments of the present disclosure are directed towards devices and methods for discovering and waking up dormant access nodes in cellular networks. In one embodiment, the dormant access nodes passively participate in a device-to-device discovery process to identify potential user equipment nearby. Upon identifying a potential user equipment, the dormant access node may wake itself up and inform a serving access node that that is able to service the user equipment. In another embodiment, dormant access nodes may transmit a discovery message periodically. Upon receiving the discovery message a user equipment may report the availability of the dormant access node to its serving access node.

    Abstract: Techniques are described herein for fast and efficient discovery of small cells by user equipment (“UE”) in a wireless telecommunications network. The small cells may operate at a high frequency band (“HFB”), which may correspond to higher frequencies than other cells (e.g., base stations, such as evolved Node Bs (“eNBs”)) of the network. The UE may receive assistance information, which may include polling channel configurations, beamforming weights, carrier frequencies, cell identifiers of small cells, and/or other information. The UE may use the assistance information when outputting (either omnidirectionally, pseudo-omnidirectionally, or directionally) a polling sequence, in order to detect the small cells.

    Abstract: Embodiments described herein relate generally to a communication between a user equipment (“UE”) and an evolved Node Bs (“eNBs”) in a plurality of frequency bands. An eNB may transmit cross-carrier, cross-subframe scheduling information to a UE in a licensed frequency band. In response reception of the scheduling information, the UE may sense a wireless transmission medium to determine if the medium is idle. If the medium is idle, the UE may generate and transmit a request to reserve the medium in the unlicensed frequency band (e.g., a Clear-to-Send message). The eNB may transmit downlink data to the UE in the unlicensed frequency band. Other embodiments may be described and/or claimed.
