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 and apparatus may include transmitting a single-cell point-to-multipoint information request to a network node. The single-cell point-to-multipoint information request indicates a first service is provided by the network node. The method may include receiving a single-cell point-to-multipoint information response. The single-cell point-to-multipoint information response indicates whether the first service is provided by the network node. The method may also include transmitting a first message to user equipment. The first message indicates to the user equipment whether or not the first service is provided by the network node.

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: An example technique is provided for receiving, by a base station in a wireless network, a priority map that indicates a mapping of a first set of priority classes for one or more radio bearers provided between the base station and a relay user device and a second set of priority classes for one or more proximity services (ProSe) sidelink logical channels provided between the relay user device and a remote user device, and allocating (or scheduling), by the base station based on the priority map, wireless resources to the relay user device to transmit data to the remote user device for one or more of the ProSe sidelink logical channels.

Abstract: An apparatus and method are provided. A request is received from a first user equipment to schedule communication resources for a device to device communication between the first user equipment and at least one second user equipment. Control information relating to the device to device communication is sent to the at least one second user equipment in response to the request.
