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: Methods, systems, and devices for wireless communications are described, in which a user equipment (UE) may communicate with one or more other UEs using sidelink communications. Multiple UEs may form a sidelink communications group and provide for sidelink groupcast communications in which an identification of a UE is determined based at least in part on a member identification of the UE within the group. Each UE in the group may determine feedback resources for acknowledgment feedback within the group based on a UE identification and a size of the group.

Abstract: Wireless communications systems and methods related to sidelink communications in a TDD system are provided. A first user equipment (UE) may receive from a base station (BS), a time-division-duplexing (TDD) configuration. The first UE may select a first TDD configuration from a set of configured TDD configurations based on the TDD configuration. Additionally, the first UE may transmit to a second UE, an indication of the first TDD configuration. The first and the second UEs may communicate a sidelink communication based on the first TDD configuration. Other features are also claimed and described.

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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first kind of synchronization signals from a first synchronization source and may receive a second kind of synchronization signals from a second synchronization source. Additionally, the UE may determine a first priority for the first synchronization source and a second priority for the second synchronization source based on whether each synchronization source is connected to a global navigation satellite system from information in the synchronization signals. Accordingly, the UE may then select the synchronization source with the higher priority and communicate with one or more additional UEs based on synchronizing with the selected synchronization source. In some cases, the first kind of synchronization signals may include sidelink synchronization signals, and the second kind of synchronization signals may include data-based synchronization signals (e.g., demodulation reference signals).

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a first user equipment (UE) within a coverage area of a base station may determine a power control configuration. The first UE may transmit an indication of the power control configuration to a second UE, which may adjust one or more power control parameters based on the indication. The one or more power control parameters may include a target received power, a compensation factor, a downlink path loss between the base station and the first UE, or a combination thereof. The second UE may use the adjusted one or more power control parameters to determine a transmit power and may transmit a message to the first UE with the determined transmit power. In some cases, the second UE may be outside of the coverage area of the base station.

Abstract: Methods, systems, and devices for user equipment (UE) device-to-device sidelink wireless communications with transmit power adjustments provided through transmit power control requests. A group of UEs may use sidelink groupcast transmissions for communications, and a sidelink groupcast transmitter may increase or decrease transmission power of the groupcast transmissions for more efficient and reliable transmissions. Each UE that receives groupcast transmissions from the sidelink groupcast transmitter may have a different set of wireless resources that may be used to transmit a transmit power control indication to request higher or lower transmit power at the transmitting UE. Alternatively, wireless resources for providing the transmit power indications may be separately provided for TPC-UP indications and for TPC-DOWN indications.

Abstract: Aspects described herein relate to selecting a sidelink control information (SCI) format for indicating a minimum communication range parameter, where the SCI format is a common format defined for requesting both location-based feedback and signal strength-based feedback. SCI indicating a value for the minimum communication range parameter can be generated based on the SCI format. The SCI indicating the value for the minimum communication range parameter can be transmitted to one or more devices.

Abstract: Methods, systems, and devices for wireless communications are described. A device may determine a set of parameters related to a transmission of a packet. For example, a device may determine a transmission range indication for the packet, a Quality-of-Service (QoS) of the packet, or a combination thereof. The device may then determine a resource exclusion parameter related to the transmission of the packet based in part on the set of parameters. Following the determination, the device may transmit, to one or more other devices in a wireless communications system, control signaling including the resource exclusion parameter.
