Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with enabling timing source selection and deselection in a decentralized manner for distributed D2D synchronization in densely populated communications systems. In an example, a communications device, functioning in a non-timing source (TS) mode, is equipped to receive a request for timing information during a synchronization channel. The communications device may further be equipped to determine whether to switch to a TS mode based on a selection utility metric value. In another example, a communications device, functioning in a TS mode, is equipped to transmit a TIB during a synchronization channel, and determine whether to switch to a non-TS mode based on a deselection utility metric value. In the TS mode, the UE is configured to transmit a TIB, while in the non-TS mode the UE is configured not to transmit the TIB.

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 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: 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, systems, and devices are described for managing a multimedia broadcast multicast service (MBMS). In one configuration, service announcement information for at least one MBMS may be received. At least a subset of the service announcement information may be broadcast in a peer discovery signal. Content of the at least one MBMS may then be relayed to at least one mobile device operating outside a coverage area of a base station. In another configuration, an out-of-coverage status indicator or MBMS query may be broadcast in a first peer discovery signal, and a second peer discovery signal may be received from at least one MBMS relay device. The second peer discovery signal may include at least a subset of service announcement information for at least one MBMS.

Abstract: Methods, systems, and devices are described for improving communications of a machine type communications (MTC) device. In a method of communication, a signal to interference noise ratio (SINR) of one or more resource blocks (RBs) of a target device may be estimated by, for example, an MTC device. The MTC device may then select one or more of the RBs of the target device to be in a resource pool based at least in part on the estimated SINR. In some embodiments, the MTC device may compare the estimated SINR of the one or more RBs of the target device to a threshold SINR and select one or more RBs with an SINR less than the threshold SINR to be in the resource pool. In some embodiments, the MTC device may randomly select a resource block from the resource pool and transmit on the selected resource block.

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: 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.
