Abstract: FCH locations are mapped to preamble sequence sets to allow more than three stations to transmit their FCHs with minimized or reduced interference. A lower interference environment may be provided to transmit the FCH within each DL relay phase when the number of stations within the phase is less than the number (L) of distinct FCH locations. With more than L stations in a DL relay phase, a reduced interference environment for FCH transmission may be achieved by assigning the same FCH location to RSs that are far away from each other.

Abstract translation: FCH位置被映射到前导序列集合以允许三个以上的站以最小化或减小的干扰来传送它们的FCH。 当相位内的站数小于不同的FCH位置的数量（L）时，可以提供较低的干扰环境以在每个DL中继阶段内发送FCH。 在DL中继阶段中有超过L个站，可以通过将相同的FCH位置分配给彼此远的RS来实现用于FCH传输的减少的干扰环境。

Abstract: The techniques introduced here provide for network assisted device-to-device communication for peer-to-peer applications. The techniques include registering a user's peer-to-peer application identifier with a peer-to-peer application server, registering a peer-to-peer application with a device-to-device server, sending a peer-to-peer service request to the peer-to-peer application server, and receiving network assistance in discovering a peer with the desired P2P content/service and establishing a device-to-device communication arrangement for exchange of peer-to-peer services.

Abstract: Session continuity may be maintained when communication devices transition from communicating through network infrastructure (e.g., through a cellular network) to direct mode communications (e.g., a communication path directly between two communication devices). For example, in switching from an infrastructure mode communication path to a direct mode communication path, a method may include: determining a public-facing address corresponding to the infrastructure path; replacing, for a packet that is to be transmitted over the direct mode communication path to a second communication device, a source address field of the packet with the determined public-facing address; and encapsulating the packet with source and destination address fields corresponding to the first and second communication device through the direct mode communication path respectively.

Abstract: Embodiments of system and method configurations for device discovery and connection establishment in connection with use of device-to-device (D2D) and proximity-based services are generally described herein. In some examples, an evolved packet core (EPC) of a 3GPP Long Term Evolution or 3GPP Long Term Evolution-Advanced (LTE/LTE-A) network is arranged to assist D2D identification and discovery procedures at user equipment (UEs) connected to the LTE/LTE-A network. Various identification and discovery procedures may be implemented in connection with proximity detection and the establishment of communication times for the establishment of the D2D communication link, between the UEs. Accordingly, the EPC of the LTE/LTE-A network may assist the establishment of a device-to-device communication link between UEs on a wireless network employing a distinct wireless protocol (for example, a direct wireless network connection via a wireless local area network (WLAN) or wireless personal area network (WPAN)).
