Abstract: A user equipment (UE) is configured to scan for device-to-device synchronization sources based on scanning configuration information. The UE is configured to report detection of a device-to-device synchronization source to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB) in response to determining that the device-to-device synchronization source meets one or more reporting requirements of the scanning configuration information. The UE is configured to receive a communication from the eNB enabling the UE as a synchronization source and transmit signals to provide a synchronization reference to one or more in-range UEs including the device-to-device synchronization source.

Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing dynamic resource allocation (DRA) of resources for machine-type communication (MTC), as a secondary partition within a system bandwidth. Allocations outside the secondary partition are configured as a primary partition for other than MTC. Apparatuses may perform MTC communications within the secondary partition when DRA configuration information includes allocation information for the secondary partition and the apparatus is configured for MTC. Otherwise, if the apparatus is other than MTC, the apparatus may refrain from performing communications in the secondary partition. Other embodiments are described.

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: Wireless communication devices may directly communicate within groups of wireless communication devices using Layer-2 communications to implement “push-to-talk” type applications. In one implementation, a method may include generating a floor request signaling message to take control of a communication channel for a group. After transmitting data relating to the communications, a floor release signaling message may be generated and transmitted a number of times.

Abstract: Technology for an eNodeB operable to resolve predefined types of concurrent communications at a relay user equipment (UE) is disclosed. The eNodeB can identify the relay UE that is configured to relay proximity services (ProSe) traffic between the eNodeB and a remote UE. The relay UE can be in-coverage of the eNodeB and the remote UE can be in-coverage or out-of-coverage of the eNodeB. The eNodeB can communicate control signaling to at least one of the relay UE and the remote UE to resolve predefined types of communications performed at the relay UE or the remote UE to defined subframes. The control signaling can provide concurrency avoidance at the relay UE for predefined types of concurrent communications between the relay UE and at least one of the eNodeB and the remote UE.

Abstract: Techniques for unifying split bearers at user equipment (UE) in an Evolved-Universal Terrestrial Radio Access-New Radio (E-ULTRA NR) dual connectivity (EN-DC) environment are described. According to various such techniques, a radio resource control (RRC) message can include an encapsulated configuration for a secondary cell group (SCG). Packet data convergence protocol (PDCP) configurations for MN or SN split bearers can be included in the master cell group (MCG) configuration in the RRC message or in the encapsulated SCG configuration. In some examples, an RRC message can include an encapsulated SCG configuration and an encapsulated PDCP configuration, where the encapsulated PDCP configuration including PDCP configuration information for the MN or SN split bearer. Other embodiments are described and claimed.
