    Abstract: A method, an apparatus, and a computer program product for wireless communication are described. The apparatus wirelessly transmits a reservation signal intended for a plurality of receivers for scheduling a broadcast/multicast data transmission, monitors for a confirmation signal from at least one of the plurality of receivers, wirelessly transmits the broadcast/multicast data transmission to the plurality of receivers if the confirmation signal is received, and suppresses transmission of the broadcast/multicast data to the plurality of receivers if the confirmation signal is not received. In some embodiments, the apparatus further determines at least one of a number of received confirmation signals or a signal strength of a received confirmation signal from the at least one of the plurality of receivers, and suppresses transmission of the broadcast/multicast data based on the determined at least one of the number of received confirmation signals or the signal strength of the received confirmation signal.

    Abstract: Systems and methods are disclosed for using a monitoring application to measure channel state information during idle cycles in a mission-critical application. A first wireless communication device determines whether there is a mission-critical data packet to be transmitted to a second wireless communication device. If not, the first wireless communication device determines whether a monitoring packet should be transmitted to the second wireless communication device. If the first wireless communication device determines a monitoring packet should be sent, the first wireless communication devices transmits a monitoring packet containing an identifier and a reference signal to the second wireless communication 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 for wireless communication are described. A user equipment (UE) may act as a relay device and receive a message from a source device. The message may include a latency indicator. The UE may identify a delay-tolerance metric associated with the message based on the latency indicator. The UE may identify, for each air interface of a set of air interfaces, a cost metric associated with transmitting the message. The UE may select an air interface from the set of air interfaces based on the delay-tolerance metric and the cost metric. The UE may transmit the message to a destination device on the selected air interface.
