Abstract: A method, apparatus, and computer-readable medium for transmission control include receiving, at a non-access stratum protocol layer, a packet including a reliability request from an application, and determining if the application is authorized to make the reliability request. Further, the aspects include, in response to determining the application is authorized to make the reliability request, performing one of: sending the packet including the reliability request to an access stratum protocol layer, or sending the packet with a modified reliability request to the second protocol layer. Additionally, the aspects include transmitting the packet. Further aspects describe a control plane delivery mechanism for provisioning UE, such as with policies and/or configurations including transmission control reliability authorization information.

Abstract: Aspects of the present disclosure describe indicating per-packet quality of service (QoS) in communications by a wireless communications device. A packet from an application generated for a first radio access technology (RAT) can be obtained, where the packet includes a first QoS value associated with the first RAT, and/or the first QoS value can be mapped to a second QoS value associated with the second RAT. In another example, the QoS value can be indicated in the packet along with a reflective indicator indicating to use the QoS value in transmitting a response to the packet.

Abstract: Features of the present disclosure implementing techniques that allow the user equipment (UE) to autonomously (e.g., without the network control) manage timing synchronization of a plurality of carriers using sidelink synchronization signal (SLSS) from one or more other UEs in order to identify a synchronization source. A synchronization source associated with a frequency carrier from a set of frequency carriers may be selected according to one or more SLSS sync source selection techniques or rules. For instance, the described solution may be utilized to enable UEs to autonomously perform V2X carrier aggregation (CA). In some examples, the synchronization carrier(s) to be searched may be determined based on the SLSS capability of the UE (e.g., transmission and reception of SLSS capabilities of the UE).

Abstract: An apparatus for wireless communication of a UE determines to transmit data in a set of RBs to at least one other UE in at least one subframe. The at least one subframe includes a first subset of symbols configured for use for transmission collision avoidance signaling and a second subset of symbols configured for transmitting the data. The apparatus determines a subset of symbols of the first set of symbols within the set of RBs of the at least one subframe for transmitting at least one concatenated sequence. The apparatus transmits the at least one concatenated sequence in each symbol of the determined subset of symbols within the set of RBs of the at least one subframe to indicate that the data will be transmitted in the second set of symbols within the set of RBs of the at least one subframe.

Abstract: One problem with current D2D communications is that there is no physical layer feedback (e.g., HARQ feedback) for unicast sidelink communications. That is, the transmitting UE does not know if the receiving UE receives and/or properly decodes the unicast transmission. Instead, current D2D communications require that a transmitting UE send a unicast sidelink communication multiple times to increase the chances that the unicast sidelink communication is received by the receiving UE. By blindly transmitting unicast sidelink communications multiple times, the spectral efficiency and radio resource utilization of the network is decreased. The present disclosure provides a solution to this problem by enabling HARQ feedback for unicast sidelink communications that improves the spectral efficiency and also enables better radio resource utilization for the network.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines a first link quality. The first link quality indicates a link quality of a first link between a first potential relay UE and the remote UE. The apparatus determines a second link quality. The second link quality indicates a link quality of a second link between the first potential relay UE and a first base station. The apparatus ranks the first potential relay UE relative to a second potential relay UE. The ranking of the first potential relay UE is based on a combination of the first link quality and the second link quality. The apparatus selects one of the first potential relay UE and the second potential relay UE for a relay connection based on the ranking of the first potential relay UE relative to the second potential relay UE.

Abstract: An efficient approach for a mobile device apparatus that is out of network coverage to communicate with the network is desired. The apparatus may be a user equipment (UE). The apparatus receives one or more device-to-device (D2D) signals respectively from one or more proximate UEs. The apparatus measures signal strength of the one or more D2D signals based on signal strength of one or more resource elements used for receiving one and/or more reference signals of the one or more D2D signals or signal strength of one or more resource elements used for receiving one or more data parts of the one or more D2D signals. The apparatus selects one of the one or more proximate UEs as a relay UE based on the measurement of the signal strength of the one or more D2D signals, to communicate with the base station via the selected relay UE.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a wireless communication user equipment (UE). The apparatus transmits information in a device-to-device (D2D) communication to a second UE, the information indicating whether the second UE should use a direct feedback path to the UE or an indirect feedback path to the UE. The apparatus receives feedback through one of the direct feedback path or the indirect feedback path based on the information indicated in the D2D communication. The apparatus receives a D2D communication from a second UE. The apparatus determines whether to transmit feedback in response to the D2D communication via a direct feedback path to the second UE or via an indirect feedback path to the second UE. The apparatus transmits the feedback in response to the D2D communication in the determined feedback path.
