    Abstract: Methods, systems, and devices are described for acquiring a network by a user equipment (UE) by concurrently scanning for a network signal on supported frequencies by two or more antennas. In one aspect, a method may include searching by a first antenna for a first signal on a first group of supported frequencies while concurrently searching by a second antenna for the first signal on a second group of supported frequencies. The method may further include acquiring the first signal from the first antenna on a first frequency, and tuning the second antenna to the first frequency to acquire the wireless network. In one aspect, the first and second groups of supported frequencies may represent frequencies within a single frequency band or frequencies in multiple frequency bands. In one aspect, supported frequencies may be divided into multiple groups and each group may be searched by a corresponding antenna.

    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.

    Abstract translation: 一种用于改善LTE-Direct通信系统中的设备到设备（D2D）通信的方法包括：通过LTE-Direct连接在第一用户设备（UE）和第二UE之间通过第一网络资源交换第一 由用于LTE-Direct连接的基站分配给第一和第二UE的一组网络资源。 该方法还包括由第一UE确定与第一网络资源的LTE-Direct连接的第一链路质量是否低于链路质量阈值。 如果是，则将LTE-Direct连接转移到第一组网络资源的另一网络资源，直到建立具有等于或大于链路质量阈值的链路质量的LTE-Direct连接。

    Abstract: The disclosure 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, 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 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 from the update device over an out-of-band D2D connection.

    Abstract: The disclosure 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 a cell overlap region. For example, the D2D peers may exchange 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 thereon. The D2D peer(s) 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) 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.

    Abstract translation: 本公开涉及动态小区重选以改善设备到设备（D2D）通信，其中两个或更多个D2D对等体驻留在不同小区上，并且一个或多个D2D对等体位于小区重叠区域中。 例如，D2D对等体可以通过（小区间）D2D连接来交换通信参数，并且基于此检测D2D对等体是否驻留在不同的基站（即附接到不同的小区）上。 然后，小区重叠区域中的D2D对等体可以获得相邻小区的测量，并且可以在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对等体驻留在相同小区 从而将小区间的D2D连接转换为小区内的D2D连接。

    Abstract: Methods, systems, and devices for wireless communication are described for redirection of a session initiation protocol (SIP) INVITE. A multi-subscriber identification module user equipment (multi-SIM UE) may intelligently determine when to redirect a SIP INVITE message to control on which of multiple networks a communication session is established. The multi-SIM UE may receive a SIP INVITE from a first user equipment (UE) requesting to establish a SIP session on a first network, the SIP INVITE including a first network address of the multi-SIM UE that is associated with a first SIM of the multi-SIM UE. The multi-SIM UE may, based at least in part on determining that a redirection criterion is satisfied, transmit a SIP redirection response including a second network address of the multi-SIM UE on a second network that is associated with a second SIM of the multi-SIM UE.
