摘要： Methods, systems, and devices are described for signaling protocols for proximity service functions in a wireless communication system. A first wireless device may identify a wireless relay requirement associated with the first wireless device. A proximity service protocol may be initiated between the first wireless device and a second wireless device based at least in part on the identified wireless relay requirement. The proximity service protocol may be initiated prior to an initiation of a communication data exchange between the first wireless device and the second wireless device. A relay link may be established, via the ProSe protocol, between the first wireless device and the second wireless device based at least in part on the identified wireless relay requirement.

摘要： Methods, systems, and devices are describe for signaling protocols for device-to-device discovery operations in a wireless communication system. A user equipment (UE) may be communicating with a serving base station using a first frequency in a first frequency band. The UE may transmit, to the serving base station, information associated with performing a discovery scan procedure on a second frequency in a second frequency band during a discovery scan interval. The first frequency may be different from the second frequency. The UE may identify a capability to skip one or more downlink transmissions from the serving base station during the discovery scan interval.

摘要： Methods, systems, and devices are describe for signaling protocols for proximity service functions in a wireless communication system. A first wireless device may identify a group identity parameter associated with a multicast transmission of multimedia content. The first wireless device may map the identified group identity parameter to an identification parameter associated with at least one proximity service (ProSe) relay wireless device. The first wireless device may receive the multicast transmission of the multimedia content via the at least one ProSe relay wireless device based on the mapping of the identified group identity parameter to the identification parameter.

摘要： Methods, systems, and devices are described that provide for D2D synchronization. The methods, systems, and/or devices may include tools and techniques that provide for synchronizing a mobile device based on detection of a reliability alarm. A reliability alarm may be used between mobile devices, which is transmitted and/or received on specific D2D resources. Since the resources are reserved for the reliability alarm, a mobile device which was previously isolated from network synchronization will be able to receive the reliability alarm that a reliable synchronization signal is close when it moves within range of a reliable device. Once a reliability alarm is received the mobile device may free other resources to allow it to receive synchronization signals from the reliable devices. The mobile device may then synchronize with the network based on the received synchronization signals and transmit its own reliability alarm for subsequent isolated devices to use.

摘要： Methods, systems, and apparatuses are described for wireless communication at a cell. The cell may transmit, from the cell to a plurality of neighboring cells, a frame configuration message. The frame configuration message may identify the current frame as a switching frame capable of dynamically switching a communication direction. The cell may switch, based at least in part on the frame configuration message, a communication direction between the cell and a user equipment (UE) for at least a portion of the current frame. The cell may communicate with the UE during the current frame according to the switched communication direction.

摘要： Methods and apparatus are described for refining, e.g., reducing, a paging area corresponding to a user equipment device, e.g., a cellular inactive UE device. Various embodiments are well suited for communications systems in which user equipment devices participate in peer to peer communications networks in which direct user device to user device communications are employed. A user equipment device participating in a peer to peer network transmits discovery signals. A femto base station and/or a cellular active UE device in the local vicinity of the UE device transmitting the peer to peer discovery signal eavesdrops on the peer discovery signaling and detects the presence of the cellular inactive UE device. The detection of the cellular inactive UE device is reported to a MME. The MME determines a paging area corresponding to the detected UE device based on the reported information and the location of the reporting device.

摘要： A communications system includes a plurality of different types of small coverage area base stations, e.g., femto cell base stations, WiFi access points and Bluetooth access points within a macro cell. Different user equipment (UE) devices, e.g., different smartphones, include different capabilities. In order for UE devices and small coverage area base stations with compatible capabilities to efficiently discover one another, the various small coverage area base stations and various UE devices utilize the macro cell communications band and macro cell communication protocol to coordinate device discovery and exchange discovery information and control information which allows a UE device to access a compatible small coverage area base station and subsequently communicate user data, e.g., traffic data, with the UE device.

摘要： Methods, systems, and devices for wireless communication are described. The methods, systems, and devices may include receiving control information from a serving station, synchronizing with an end device based at least in part on the control information received from the serving station, and receiving an acknowledgement (ACK) from the end device in response to the synchronizing, the ACK indicating the end device is synchronized with the relay device. The methods, systems, and devices may also include receiving a data packet from the end device subsequent to the synchronizing, and transmitting, to the serving station, the data packet received from the end device, the transmitting based at least in part on the control information received from the serving station.
