Abstract: Methods, systems, and devices are described for signaling device-to-device (D2D) capability information. A user equipment (UE) may determine a frequency band list of frequency bands supported for D2D proximity service communications. Based on the frequency band list, the UE may determine a proximity service record for a frequency band combination parameter, the frequency band combination parameter associated with non-D2D communications. The proximity service record may include a reduced capabilities record for the frequency band combination parameter that indicates reduced capabilities for non-D2D communications when D2D proximity service communications are active.

Abstract: Methods, systems, and devices are described for improving resource management in wireless communications. More particularly, the methods systems and devices relate to techniques for suspending bearers when not required, for example, for D2D communications. In one example, a mobile device may send a connection request that indicates a service type. The connection request may be a service request (SR) or an extended service request (ESR). A set of bearers may be established for the intended communication(s). The indicated service type may not require all bearers of the set of bearers such that at least one bearer may be suspended.

Abstract: Methods, systems, and devices are described for device-to-device (D2D) wireless communication. A device may transmit an initiation message to a base station indicating that the device desires to initiate a D2D communication session. The device may then receive a response from the base station that includes parameters for configuration of the D2D session. When it has data to send to another device, the device may transmit buffer status report (BSR) to the base station. The base station may respond with a grant of D2D scheduling assignment (SA) configured according to the previously sent parameters. For example, the message may be scrambled with a D2D temporary identity sequence. In some cases, the device may transmit a group identification (ID) code to the base station, and the group ID may be associated with an index, so an SA for that group can be reference by index.

Abstract: Certain aspects of the present disclosure provide techniques for improving sidelink positioning via messaging between wireless nodes, e.g., roadside service units (RSUs). A method that may be performed by a user equipment (UE) includes receiving a first positioning reference signal (PRS) from a first wireless node, receiving a second PRS from a second wireless node, receiving, from the first wireless node, an estimate of a first clock error component between the first wireless node and the second wireless node, and estimating a position of the UE, based on the first PRS, the second PRS, and the estimate of the first clock error component.

Abstract: Certain aspects of the present disclosure provide techniques for multiplexing HARQ feedback in a same slot for downlink and sidelink transmissions. An example method generally includes receiving, from a network entity, a downlink control information (DCI) that schedules resources for at least one physical sidelink shared channel (PSSCH) transmission from the first UE to a second UE, transmitting data to the second UE via the at least one PSSCH transmission using the scheduled resources, receiving, from the second UE, acknowledgment feedback for the at least one PSSCH transmission, selecting at least one codebook entry for providing feedback for at least one downlink transmission from the network entity to the first UE and the acknowledgment feedback for the at least one PSSCH transmission in a same physical uplink control channel (PUCCH) slot, and transmitting the at least one codebook entry to the network entity via at least one PUCCH transmission.

Abstract: Various aspects of the disclosure relate to a request-response mechanism for sharing sensor information. For example, sensor devices (e.g., in vehicles, fixed structures, or a combination thereof) may selectively share information acquired by the sensor devices. The disclosure relates in some aspects to avoiding redundant transmissions of sensor information. For example, a sensor device of a set of sensor devices may determine which sensor device should transmit information and/or the time(s) at which that sensor device should transmit the information.

Abstract: Systems, methods, and devices for sidelink positioning determination and communication can employ techniques including obtaining, at a first sidelink-enabled device, data from one or more data sources indicative of one or more criteria for using either round-trip time (RTT)-based positioning of a target node or single-sided (SS)-based positioning of the target node. The techniques also include selecting, with the first sidelink-enabled device, a positioning type from the group may comprise of RTT-based positioning and SS-based positioning, based on the data. The techniques also include sending a message from the first sidelink-enabled device to a second sidelink-enabled device, where the message includes information indicative of the selected positioning type.

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. A communication device, which may be otherwise known as user equipment (UE), may receive a data transmission and determine a slot to transmit a hybrid automatic repeat request (HARQ) feedback based on the data transmission. The communication device may determine one or more HARQ feedback resources or one or more HARQ feedback resource sets in the slot to transmit the HARQ feedback, where the one or more hybrid automatic repeat request feedback resources or the one or more hybrid automatic repeat request feedback resource sets in the slot comprises a set of frequency resources associated with the slot, and transmit the HARQ feedback using the one or more HARQ feedback resources or the one or more HARQ feedback resource sets in the slot.
