Abstract: Opportunistic wide area network (WAN) connectivity for sensor devices with low transmit power, triggered by sensor device broadcasts, is disclosed which increases the likelihood of the sensor devices' data messages reaching the base station. Multiple sensor devices within proximity to each other establish device to device links. When a sensor device successfully connects to the base station, the base station informs the sensor device selected as a gateway, which in turn broadcasts its identification to peer sensor devices by way of a multi-hop rebroadcasting scheme. This triggers a multi-hop forwarding scheme where sensor devices that receive the broadcast forward their data messages via the D2D links to other peers until their data messages reach the gateway sensor device. The gateway sensor device forwards data messages it receives to the base station, so that the base station receives data packets from multiple sensor devices via the gateway sensor device.

Abstract: In a scenario where peer devices (e.g., machine-to-machine devices, machine type communication devices, and so on) have limited transmission capabilities, the peer devices may upload data to another device. For example, data may be uploaded to a base station directly or via a relay device (e.g., a user equipment). Connectivity to the base station or relay device is not assured, however. To facilitate uploading of such data, the data is mutually exchanged between the peer devices. In this way, the data can be uploaded once at least one of the peer devices establishes connectivity to the base station or relay device.

Abstract: Data received from multiple devices (e.g., machine-to-machine devices, machine type communication devices, and so on) is aggregated and delivered to another device (e.g., a base station). In this way, the data is efficiently transmitted to the other device, for example, in scenarios where the devices that source the data have limited transmission capabilities.

Abstract: Techniques are provided for expedited Internet content delivery. For example, there is provided a method that involves receiving, at a communication device, a broadcast transmission outside of a spectrum allocated for Internet communications and outside of a spectrum allocated for real time programming content, wherein the broadcast transmission includes unsolicited content pushed to a group of such communication devices. The method may involve storing a portion of the unsolicited content, and receiving a request for content from a user. The method may involve providing the portion of the unsolicited content to the user, in response to the requested content matching the portion. The method nay involve determining whether the requested content is stored on another communication device of the group, in response to the requested content not matching the portion.

Abstract: Methods, systems, and devices are described for wireless communication at a UE. A user equipment (UE) may perform an initial access procedure to establish a connection with a serving cell. The UE may then arrange a regular transmission schedule with the serving cell including a discontinuous transmission (DTX) cycle and an acknowledgement schedule. The UE may enter a low power mode and refrain from any transmission during the a sleep interval of the DTX cycle. The UE may then wake up and transmit a message to the serving cell after the sleep interval without performing another access procedure. The UE may perform another access procedure to transmit at times not covered by the regular transmission schedule. For example, if an acknowledgement (ACK) for the message isn't received, the UE may perform another access procedure for retransmission.

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.

Alternatively, the apparatus may further identify at least one MTC device or UE to refrain from using resources respectively included in the at least two regions when the network congestion level is above a threshold, and transmit a congestion control signal to the at least one identified MTC device or identified UE when the network congestion level is above the threshold.

Abstract: Methods and apparatus for allocation of resources for handover related measurements in a communications system including user equipment (UE) devices, a macro base station and small base stations (e.g., femtocells) are described. Some embodiments are well suited for systems where the number of femtocells may equal or outnumber the number of UE devices. In some embodiments a macro base station allocates periodic communications resources for transmission of pilots by UEs or femtocells. The macro base station configures either femtocells or active UEs to transmit pilots using the allocated communications resources based on the relative number of femtocells to active UEs in the coverage area of the macro base station, devices which are lower in number transmitting the pilots. Transmitters (UE devices or femtocells) transmit pilots along with identification information using the allocated resource(s) and receivers measure the pilot signals. The pilot signal measurements may be used to make handover decisions.
