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 translation: 当通信设备从通信网络基础设施（例如，通过蜂窝网络）转换到直接模式通信（例如，直接在两个通信设备之间的通信路径）时，可以维持会话连续性。 例如，在从基础设施模式通信路径切换到直接模式通信路径时，方法可以包括：确定与基础设施路径相对应的面向公众的地址; 将要通过直接模式通信路径发送的分组替换为具有确定的公共地址的分组的源地址字段; 并且通过分别通过直接模式通信路径封装与第一和第二通信设备相对应的源和目的地地址字段的分组。

Abstract: Device-to-device (D2D) contention management systems and methods provide managed offloading of cellular network traffic through a contention-based network. For each link in a group of links between nodes in the contention-based network, a link cost is calculated to determine a number of potential links that may interfere with the link, if activated. Each link is evaluated in the order of ascending link cost to determine whether it complies with predefined conditions and whether activating the link increases or decreases D2D network throughput. If the link increases throughput, the link is activated.

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。
