    Abstract: Methods and devices are described for forwarding, managing, and/or detecting timing information for device-to-device discovery. Timing information may be received from a base station. A timing signal including the timing information may be transmitted. The timing signal may be transmitted during a sub-frame reserved for device-to-device discovery. Timing information for a base station may be transmitted to a user equipment (UE). Instructions to transmit a timing signal including the timing information during a sub-frame reserved for device-to-device discovery are also transmitted to the UE. Information indicating a timing of sub-frames reserved for device-to-device discovery by a neighboring base station may be received from a serving base station. A timing signal may be detected during at least one of the sub-frames reserved for device-to-device discovery. The timing signal may include timing information for the neighboring base station.

    Abstract: An apparatus may receive, from a scheduling entity, sidelink grant information in a downlink control channel. After receiving the grant information in the downlink control channel, the apparatus may transmit a request-to-send (RTS) signal comprising an indication of a requested duration of time to reserve a sidelink channel for sidelink data. If the sidelink channel is available for the requested duration of time, the apparatus may receive a clear-to-send (CTS) signal configured to indicate an availability of the sidelink channel for the requested duration of time. Subsequently, the apparatus may communicate, with another apparatus different from the scheduling entity, the sidelink data using the sidelink channel during the requested duration of time. Afterwards, the apparatus may communicate acknowledgment information corresponding to the communication of the sidelink signal with the other apparatus. Various additional and alternative aspects are described herein.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a configuration indicating multicast broadcast single frequency network (MBSFN) subframes within a radio frame. The configuration indicates a number of symbols of an MBSFN subframe for receiving a wide area network (WAN) control signal and remaining symbols of the MBSFN subframe dedicated for peer-to-peer communication. The apparatus communicates with a peer via the symbols dedicated for peer-to-peer communication. Alternatively, the apparatus receives a configuration indicating a portion at a beginning and/or end of a guard period of a special time division duplex (TDD) subframe. The portion is reserved for an uplink timing advance and/or switching from transmission to reception and/or reception to transmission. The configuration also indicates a remaining portion of the guard period of the special TDD subframe for peer-to-peer communication. The apparatus communicates with a peer via the remaining portion.

    Abstract: A user device may transmit a request to a base station for an allocation of device-to-device (D2D) discovery resources. In response to the request, the user device may receive from the base station a response that indicates whether the D2D discovery resources allocated to the user device are common or dedicated.

    Abstract: Methods and apparatus for making handoff decisions in an access terminal which can support both best effort and QoS traffic, e.g., when operating in a best effort and QoS mode of operation, respectively, are described. The access terminal receives an indicator indicating the fraction of communications resources not utilized for QoS service and information indicating a number of best effort users being supported by the attachment point. During Qos mode operation, connections to attachment points which can support the access terminal's minimal QoS requirements are identified and then from among the identified set, the attachment point which can provide a connect supporting the most best effort traffic from the access terminal is selected. In best effort mode operation the access terminal selects the attachment point connection which will provide the greatest amount of throughput to the access terminal for best effort traffic.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) that transmits sensor data to another UE may also send information about the associated sensor and its performance. For example, the UE may determine a set of rules that apply to a sensor. The set of rules may define an association between a group of performance values and a group of performance levels corresponding to one or more metrics of the sensor. The UE may identify a performance value from the group of performance values for the sensor based on a performance level of the sensor and the set of rules. After determining the performance value, the UE may transmit an indication of the set of in a first data frame of a message and an indication of the performance value in a second data frame of the message.
