Abstract: Methods, systems, and devices are described for improving uplink communications of a machine type communication (MTC) device by relaying communications through a first device, such as a mobile device or user equipment (UE), to a second device, such as a base station or Evolved-NodeB (eNB). In an embodiment, a relay device may participate in a discovery process to discover an MTC device. The relay device may then receive data from the discovered MTC device, such as through a peer-to-peer link, and relay the data to a base station through a second communication link. In another embodiment, an MTC device may participate in a discovery process with a first device, such as a relay UE. The MTC device may then transmit data to the relay UE for relaying to a second device, such as a base station. In either case, the MTC device may receive data directly from the base station.

Abstract: Methods and apparatus for controlling interference with regard to important control signals, e.g., synchronization signals and broadcast channel signals, are described. A configurable base station monitors for and receives signals from other base stations in its local vicinity and determines the implemented frame timings corresponding to the other deployed base stations. If possible, the configurable base station selects to use a frame timing offset which is different from the frame timing offsets being used by the other base stations. In some embodiments, symbol level and subframe level synchronization are maintained between the base stations; however, frame level synchronization may, and sometimes does vary. Different adjacent base stations may, and sometimes do, intentionally offset their frame boundaries by multiples of a subframe.

Abstract: 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.

Abstract: 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.

Abstract: Apparatus, methods, and computer-readable media for facilitating identifier-based transport types of a GNLP are disclosed herein. An example method for wireless communication at a transmitting UE includes receiving a message based on a GNLP, the message including a GNLP header. The example method also includes populating the GNLP header to indicate that the message is associated with a single-hop transport type, the single-hop transport type including a unicast message, a groupcast message, or a broadcast message. The example method also includes transmitting the message via sidelink to a receiving UE. An example method for wireless communication at a receiving UE includes receiving, from a transmitting UE, a message via sidelink, the message based on a GNLP and including a GNLP header. The example method also includes using the GNLP header to determine that the message is associated with a single-hop transport type.

Abstract: Mechanisms for performing unicast packet addressing and communication, e.g., in a C-V2X sidelink communication scenario, are provided. In one aspect, a method for wireless communication performed by a first wireless communication device includes receiving a source identifier associated with a second wireless communication device, and determining, based on the source identifier associated with the second wireless communication device and a deterministic function, a destination identifier. The destination identifier is different from the source identifier. The method further includes generating a packet comprising the destination identifier, where the destination identifier indicates a unicast packet, and transmitting the unicast packet to the second wireless communication device.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may establish connectivity to a local area network using cellular radio access technology (RAT). The UE may establish a signaling radio link with a cellular access node (AN) via a cellular RAT. The UE may transmit a connectivity request to a network node via the signaling radio link. The connectivity request may specify a connectivity type for establishing connectivity to a LAN. Based at least in part on an acceptance of the connectivity request, the UE may establish a data radio link with the cellular AN. In an example, the acceptance of the connectivity request may include at least one parameter for configuring the connectivity to the LAN. The UE may then establish a data flow for exchanging data link layer packets with the LAN via the data radio link.

Abstract: 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.

Abstract: A wireless relay device may receive a request indicating that a wireless device has one or more delay-tolerant messages to be forwarded to a network. The wireless relay device may send a response message to the wireless device indicative of an estimated time to network contact. The wireless relay device then receives and caches the delay-tolerant messages to be forwarded. The wireless relay device may forward at least one of the one or more delay-tolerant messages.

Abstract: Methods, systems, and devices for wireless communication are described. In one method, a wireless device may establish a connection with an access node (AN) of a local area network (LAN). The wireless device may also determine to perform an authentication. The wireless device may further receive an indication, as part of the authentication, of a protocol end point for the authentication as being a non-access stratum (NAS) layer or a radio resource control (RRC) layer. In another method, an AN may establish a connection with a wireless device. The AN may determine the wireless device determined to perform an authentication with an authenticator included in the AN. The AN may further indicate, as part of the authentication, a protocol end point for the authentication as being the NAS layer or the RRC layer.
