Abstract: Methods, systems, and devices are described for wireless communication. A user equipment (UE) may receive configuration information for a multimedia broadcast service including a group communication identifier and a priority indicator. The UE may then convey the information in a monitoring request to a relay UE. In some cases the information may be conveyed using the Proximity-based Service (ProSe) signaling protocol. The relay UE may use the configuration information to relay broadcast to the receiving UE. If the relay UE receives multiple priority indicators associated with the same group communication identifier (e.g., from different receiving UEs) it may use the highest priority or the most recent priority.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes configuring a relay selection rule; receiving at least one discovery message from each of a plurality of proximity services (ProSe) relay candidates providing access to a network; evaluating the received discovery messages with respect to the relay selection rule; selecting a first ProSe relay candidate from the plurality of ProSe relay candidates based at least in part on the evaluating; and connecting to the network via the first ProSe relay candidate. A method for wireless communication at a ProSe relay candidate includes receiving, from a network, a ProSe Relay Indication (PRI); broadcasting at least one discovery message that includes the PRI; and receiving a relay connection request from a UE based at least in part on a compliance of the at least one discovery message with a relay selection rule of the UE.

Abstract: Methods, systems, and devices are described for determining a monitoring schedule for device-to-device (D2D) synchronization signals. A synchronization cycle may be determined that includes a plurality of monitoring periods. The monitoring periods may be a time between at least two start times of sequential D2D synchronization signals to detect at least one of the D2D synchronization signals. Sub-monitoring periods may be determined based on the duration of the monitoring periods. The sub-monitoring periods may have a cumulative duration the same as the duration of the monitoring period and be scheduled to occur during different monitoring periods of the synchronization cycle.

Abstract: Methods, systems, and devices are described for device-to-device (D2D) wireless communication. A device may receive a timing variable from a network while the device is in a connected mode. The device may then use the timing variable for D2D discovery message authentication. The device may compare the timing variable with a local timing variable to determine whether a difference between the two variables is within a maximum allowable offset. The device may announce the D2D discovery message to another device when the difference is within the maximum allowable offset.

Abstract: A user device may receive one or more parameters from a base station to facilitate device-to-device (D2D) discovery. One of the received parameters is a discovery period parameter, which identifies a discovery period in which discovery resources are available for D2D discovery. Once the user device has received the parameters, the user device may use the parameters to participate in D2D discovery.

Abstract: Disclosed are techniques for using ranging signals to determine a position of a pedestrian user equipment (P-UE). In an aspect, a UE receives a plurality of ranging signals transmitted by one or more UEs, measures one or more properties of each of the plurality of ranging signals, and calculates an estimate of the position of the P-UE based on the one or more properties of each of the plurality of ranging signals. In an aspect, the P-UE transmits a plurality of ranging signals, receives a first message and a second message from first and second vehicle UEs (V-UEs), the first and second messages including first and second estimated positions of the P-UE and associated first and second confidences, and calculates an estimate of the position of the P-UE based on the first estimated position, the first confidence, the second estimated position, the second confidence, or a combination thereof.

Abstract: Techniques for handling sidelink feedback signaling in situations where collisions would otherwise be experienced in a network communication link are shown and described. For example, sidelink feedback signaling handling techniques may provide for collision handling when sidelink HARQ is to be simultaneously transmitted with network communication radio interface uplink channel information (e.g., Uu HARQ, SR, CSI, etc.) on one or more Uu channel (e.g., PUCCH, PUSCH, etc.). In operation of sidelink feedback handling, a transmitter or intermediary UE of a sidelink communication link may decide whether and how to forward the sidelink HARQ to a corresponding base station. Other aspects and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for determining resources for sidelink communications based on coordination information. A method that may be performed by a first wireless device includes receiving, from second wireless devices, reports indicating coordination information associated with candidate resources and assigning ranks to the reports. The method also includes determining resources from the candidate resources for communicating with third wireless devices based on at least one of: at least two reports, and the ranks of the at least two reports; or at least one of the reports and sensing information, measured by the first wireless device, associated with the candidate resources, and the rank of the reports and a rank of the sensing information. The method further includes communicating with the third wireless devices via the determined resources.
