Abstract: Methods, devices, systems, techniques, and computer program products are provided in which an eNB, within a wireless communications network, determining network coverage status relating to a cell served by it, where the eNB supports UE-to-Network relay for a remote UE using direct device-to-device communication between the remote UE and a relay UE connected to the serving cell. Based on a determination of network coverage status, at least one UE is initiated and selected to act as a relay UE. The radio interface link quality of the relay UE can be evaluated and the relay UE can be configured to send an indication of the radio interface link quality to the remote UE. Based on the determined network coverage status and selection of a relay UE, the remote UE is controlled by the eNB for the relay UE discovery and selection either directly or via the relay UE.

Abstract: Handling of related identities may be valuable in communication systems. More particularly, in areas such as long term evolution advanced (LTE-A) proximity services (ProSe), it may be useful to provide for handling of ProSe device to device (D2D) related identities at the radio access network (RAN) level. A method can include deriving an initial layer one identifier corresponding to a target user equipment or group. The method can also include determining whether the initial layer one identifier collides with another layer one identifier corresponding to a different target user equipment or group. The method can further include communicating with the target user equipment or group based on the determination of whether the initial layer one identifier collides with another layer one identifier in use.

Abstract: A method for device-to-device communication includes receiving, in a D2D-capable user terminal from a network apparatus, measurement configuration information regarding a D2D discovery resource usage status. The user terminal performs, based on the received measurement configuration information, a corresponding measurement to determine the usage status of D2D discovery resources. The user terminal transmits, to the network apparatus, a report on the measurement performed in the user terminal, the report indicating the usage status of D2D discovery resources, in order the network apparatus to be able to adjust D2D discovery resource allocation based on the report.

Abstract: To reduce handover latency experienced by a user using a user equipment that is served for offloaded user data traffic by a first small cell, a handover between a first macro cell deploying the first small cell and a second macro cell deploying a second small cell is triggered when information indicating that the user equipment has associated with the second small cell not deployed by the first macro cell is received.

Abstract: Measures are provided for management of RRC for D2D communication. Such measures include setting a connected state of RRC for device(s) of a pair of devices. For the devices(s), both a D2D communication service between the pair of devices and a core network communication service between the device(s) and a core network entity are active. The setting enables radio resource management for the device(s) for the D2D communication service and the core network communication service. Termination of the core network communication service is detected for the device(s). A connection towards the core network entity is reconfigured for disabling the core network communication service of the device(s). The connected state of RRC is maintained for the devices(s) of the pair of devices, for which the device(s) only the device-to-device communication service is active. The maintaining enables radio resource management for the device(s) for the D2D communication service.

Abstract: A method for a communications system, wherein in response to detecting a radio link problem during a first phase of a radio link failure, the first user terminal transmits an indication of the detection of the radio link problem to a second user terminal over a device-to-device link. In response to a report on the radio link problem detection of the first user terminal being sent from the second user terminal to a network apparatus, the first user terminal receives a confirmation on a status of the report from the second user terminal over the device-to-device link. Based on the confirmation, the first user terminal decides, whether to stop a first radio link failure timer, reset the first radio link failure timer, or extend the first radio link failure timer.
