    Abstract: The disclosure generally relates to dynamic cell reselection to improve device-to-device (D2D) communications where two or more D2D peers are camped onto different cells and one or more D2D peers are located in an overlap region between the cells. For example, in various embodiments, the D2D peers may exchange one or more communication parameters over the (inter-cell) D2D connection and detect that the D2D peers are camped on different base stations (i.e., attached to different cells) based on the exchanged communication parameters. The D2D peer(s) located in the cell overlap region may then obtain measurements on the neighbor cell and a forced cell reselection may be triggered at the appropriate D2D peer(s) located in the cell overlap region such that the D2D peers are camped on the same base station, thereby converting the inter-cell D2D connection into an intra-cell D2D connection that can be more easily maintained.

    Abstract translation: 本公开通常涉及动态小区重选以改善设备到设备（D2D）通信，其中两个或多个D2D对等体驻留在不同小区上，并且一个或多个D2D对等体位于小区之间的重叠区域中。 例如，在各种实施例中，D2D对等体可以通过（小区间）D2D连接交换一个或多个通信参数，并且基于交换的（小区间）D2D对等体来检测D2D对等体是否驻留在不同的基站（即，附接到不同的小区） 通讯参数。 位于小区重叠区域中的D2D对等体然后可以获得相邻小区的测量，并且可以在位于小区重叠区域中的适当的D2D对等体处触发强制小区重选，使得D2D对等体驻留在 相同的基站，从而将小区间的D2D连接转换为可以更容易地维护的小区内D2D连接。

    Abstract: The disclosure generally relates to synchronizing application account data using out-of-band device-to-device (D2D) communication between peer wireless devices. More particularly, a first device may generate a local unique expression that includes a name, one or more user credentials, and a last update time associated with an application registered for a D2D-based application synchronization service. In response to detecting one or more external unique expressions from one or more peer devices in proximity that match the name and the user credentials associated with the registered application, the first device may then identify, among the one or more peer devices, an update device associated with an external unique expression having a last update time more recent than the last update time associated with the local unique expression and request an update to synchronize the application account data associated with the registered application from the update device over an out-of-band D2D connection.

    Abstract: A method for improving device-to-device (D2D) communication in an LTE-Direct communication system includes exchanging communication information between a first user equipment (UE) and a second UE over an LTE-Direct connection with a first network resource of a first set of network resources allocated to the first and second UEs by a base station for the LTE-Direct connection. The method also includes determining, by the first UE, whether a first link quality of the LTE-Direct connection with the first network resource is below a link quality threshold. If so, the LTE-Direct connection is shifted to another network resource of the first set of network resources until an LTE-Direct connection is established that has a link quality that is equal to or greater than the link quality threshold.
