Abstract: A method, an apparatus, and a computer program product for wireless communication are provided that enable UEs to conserve power while involved in ProSe communication. The apparatus transmits discovery class information for ProSe communication to an A-UE and to an M-UE. The discovery class information may be transmitted from a PF in response to discovery requests. Discovery class rules may be sent from the PF as a part of service authorization. The discovery class information may be transmitted from a ProSe application server as application layer signaling. The A-UE and M-UE may use the discovery class information to select a pool of ProSe resources according to the discovery class information for transmission or monitoring of ProSe communication. The M-UE may use the information to reduce the number of resource pools of resources that are monitored for ProSe communication.

Abstract: Methods, systems, and devices for wireless communication are described. In one method, a wireless device may securely communicate with a local area network (LAN), via a first connection with a source access node (AN), based on a first security key. The wireless device may perform a handover from the source AN to a target AN. The wireless device may derive a second security key based on the first security key, and securely communicate with the LAN, via a second connection with the target AN, based on the second security key and a restriction policy for the second security key. The wireless device may perform an authentication procedure to obtain a third security key, which may not be subject to the restriction policy, and securely communicate with the LAN, via the second connection with the target AN, based on the third security key.

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: Example methods and apparatuses for managing polling in devices implementing proximity services are presented. For instance, an example method of polling management in a ProSe system is presented, which includes receiving, at a network entity, a polling message from a first UE. In addition, the example method may also include receiving, at the network entity and after receiving the polling message, one or both of a first location report associated with the first UE and a second location report associated with a second UE. Furthermore, the example method may include determining whether to generate a polling response message upon receiving one or both of the first location report and the second location report, wherein the polling response message includes a next polling time for the first UE that is based on a location reporting schedule associated with one or both of the first UE and the second UE.

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 access class barring (ACB) operations for device-to-device (D2D proximity service communications. An ACB parameter may be defined and assigned to UEs that is associated with discovery or communication operations for normal and high priority user equipments (UEs). The UE may identify a resource for D2D proximity service communications and, when not barred, send a radio resource control (RRC) connection message requesting the available resource. An establishment cause may be defined and included in the RRC connection request message that corresponds to the ACB parameter.

Abstract: Methods, systems, and devices for ranging are described. A multi-phase distributed ranging technique includes transmitting and receiving vehicle information messages during a first time interval, where the vehicle information messages include at least a vehicle identifier and resource information. The multi-phase technique further includes transmitting and receiving ranging signals during a second time interval, and determining times of arrival of received ranging signals. A centralized ranging technique includes receiving resource assignments from an access point, transmitting ranging signals according to the resource assignments, and determining times of arrival of received ranging signals.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting user equipments (UEs) may transmit a sidelink indication signal including a sequence (for example, wakeup signal or go-to-sleep signal) for a receiving UE to determine whether to monitor for scheduling sidelink control information (SCI) messages in one or more sidelink discontinuous reception (DRX) on durations that overlap in time. The receiving UE may determine (for example, based on an initial value in the sequence, the resource on which the sequence was received, among other examples) a location of an on duration, and may perform a DRX operation (for example, may wake up or may go to sleep) during the on duration.
