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 first user equipment (UE) in a wireless communications system, such as a vehicle-to-everything (V2X) communications systems, may communicate over sidelink to other UEs. The first UE may receive, from a base station, control signaling indicating a sidelink resource pool allocated for sidelink communication between the first UE and a second UE. The first UE may transmit an indication that superposition coding may be used to generate a concurrent sidelink and uplink transmission. The first UE may then transmit the concurrent sidelink and uplink transmission within a resource of the sidelink resource pool based on the indication. The second UE may decode the sidelink portion of the transmission, and the base station may decode the uplink portion of the transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify multiple candidate sets of physical sidelink feedback channel (PSFCH) transmissions that include hybrid automatic repeat request (HARQ) feedback for sidelink communications received from one or more peer UEs. The UE may select, from one or more of the multiple candidate sets that satisfy a PSFCH transmit power constraint, at least one candidate set that has a highest value for a utility parameter among utility parameters associated with each of the one or more candidate sets that satisfy a PSFCH transmit power constraint. The UE may transmit, on a PSFCH, the plurality of PSFCH transmissions included in the at least one candidate set in a HARQ feedback occasion. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications (e.g., vehicle to everything systems) are described relating to an adaptive design of demodulation reference signals (DMRS) density based on user equipment (UE) velocity. A UE may send assistance information to a transmitting UE to help identify a DMRS pattern based on the relative speed between the two UEs. Also, the transmitter may determine the adaptive DMRS pattern based on its speed without information of the receiver's speed. The transmitter may indicate the adaptive DMRS pattern in control information to the receiver. A base station may receive assistance information, and the base station may determine the adaptive DMRS pattern to be used by the transmitting UE based on the received assistance information and then indicate the adaptive DMRS pattern to the transmitting UE. A UE may determine an adaptive DMRS pattern to use based on feedback from the receiving UE.
