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: Apparatus, methods, and computer-readable media for facilitating scrambling of sidelink control information for sidelink communication are disclosed herein. The scrambling of the SCI may include scrambling CRC, scrambling information bits, and/or scrambling channel bits. An example method for wireless communication at a user equipment UE includes scrambling at least a portion of SCI. The example method also includes transmitting the SCI carrying control information for a sidelink transmission. In another aspect, an example method for wireless communication at a UE includes receiving SCI having scrambled bits. The example method also includes decoding the SCI based on information known to the UE.

Abstract: A transmitting user equipment (UE) may perform resource hopping for a periodic sidelink resource reservation by scheduling a plurality of periodic sidelink resources with a first periodicity, the plurality of periodic sidelink resources being shifted at a first offset in a frequency domain. The transmitting UE may reduce persistent collisions of periodic or semi-persistent scheduling (SPS) reservation of the sidelink resources with another UE. The transmitting UE may transmit, to a receiving UE, sidelink control information (SCI) indicating the first offset and the plurality of sidelink transmissions via the plurality of periodic sidelink resources at the first periodicity based on the SCI. The receiving UE may receive, from the transmitting UE, the SCI and the plurality of sidelink transmissions via the plurality of periodic sidelink resources at the first periodicity based on the SCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may transmit, from the mobile station to an encoding device, acknowledgement or negative acknowledgement (ACK-NACK) feedback based at least in part on a transmission by the encoding device, wherein the ACK-NACK feedback is associated with a feedback bin, and wherein the feedback bin is associated with a location of the mobile station. The mobile station may receive, at the mobile station from the encoding device, a network coding transport block, wherein the network coding transport block is formed based at least in part on the transmission and the ACK-NACK feedback associated with the feedback bin. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may identify a first set of resources for an access link communication between the first UE and a base station. The UE may identify a second set of resources for a sidelink communication between the first UE and a second UE. The UE may identify a scheduling conflict between the first set of resources for the access link communication and the second set of resources for the sidelink communication. The UE may drop at least a portion of the first set of resources for the access link communication or the second set of resources for the sidelink communication based at least in part on the identification of the scheduling conflict and a prioritization rule.
