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: 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.
