Abstract: Systems and methods for enabling proximity services to be delivered as part of an application service and/or for providing tailored services and/or a differential quality of service (QoS) to a flow may be disclosed. For example, a temporary service name between an application and a server such as a D2D server may be established such that a UE and/or network may execute such a service at a later time without later involvement by the application and/or without exchanging credentials for the application with the network and vice versa.

Abstract: A method and apparatus for neighbor discovery in a wireless communication system are disclosed. A neighbor seeking wireless transmit/receive unit (WTRU) may send a first beacon based on configuration information provided by the network. The neighbor WTRUs receive the first beacon and may send either a report to the network or send a second beacon to the neighbor seeking WTRU. The network may then provide neighbor WTRU information to the neighbor seeking WTRU. The neighbor discovery may be performed within a pre-defined group of WTRUs that is formed based on proximity to the WTRU and/or an attribute of the WTRU. The neighbor discovery procedure may be performed to find neighbor WTRUs in case where a WTRU fails to find any network. A neighbor list may be generated by the neighbor seeking WTRU by measuring reference signals transmitted by neighbor WTRUs on an uplink to the network.

Abstract: Disclosed herein is HARQ management, scheduling, and measurements, among other things, for cooperative communication. For example, methods herein may be used in situations wherein relaying or helping mechanisms may comprise the use of a relay node which is part of a fixed infrastructure or a relay node which may be a mobile wireless transmit/receive unit (WTRU). In said situations, a first transmission with first data is established between an evolved NodeB (eNB) and a WTRU. A second transmission with second data is established between a relay node (RN) and the WTRU. Said first and second data are combined for decoding. A single HARQ feedback for said first and second transmissions is sent from the WTRU to the eNB.

Abstract: A method and apparatus are described for maintaining communications over a bearer when at least one of two wireless transmit/receive units (WTRUs) transition to idle mode. In one case, a direct WTRU-to-WTRU bearer may be released in response to a first one of the WTRUs transitioning to idle mode. A second one of the WTRUs may send a first of a plurality of packets to the first WTRU via a default packet data network (PDN) connection or a default bearer towards the PDN connection. The first packet may have a destination Internet protocol (IP) address of the second WTRU and trigger paging to the first WTRU.

A method and apparatus for initiating proximity service bearer establishment is also described.
