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. 1one or more processors; and obtain information related to the group including a layer-2 group identifier (ID) and an upper layer group ID;', a destination layer-2 address for the proximity-based direct communication, wherein the destination layer-2 address is based on the layer-2 group ID, and', 'the upper layer group ID; and, 'generate a frame having, 'transmit the frame to the one or more other UEs affiliated with the layer-2 group ID., 'one or more device-readable media having instructions stored thereon that, when executed by the one or more processors, cause the UE to. An user equipment (UE) for proximity-based direct communications with one or more other UEs of a group, comprising: This application is a continuation of co-pending U.S. patent application Ser. No. 14/765,285, titled “MULTICAST-BASED GROUP COMMUNICATIONS IN AD HOC ARRANGEMENTS OF WIRELESS DEVICES,” filed Jul. 31, 2015, the contents of which are incorporated herein in their entirety. The present application also claims the benefit of PCT Application PCT/US2013/074673, which was filed on Dec. 12, 2013, and which claims the benefit of U.S. Provisional Patent Application No. 61/771,698, which was filed on Mar. 1, 2013, and which is hereby incorporated by reference as though fully set forth herein.Wireless networks may provide network connectivity to mobile communication devices, such as smart phones. The network connectivity may be provided through radio interfaces. Typically, the devices may connect to a network through an access point that ...
