Abstract: An apparatus may comprise a component for communicating using a first RAT and another component for communicating using a second RAT. Overlapping communication using the two RATs may cause problems for proper reception at the apparatus. The apparatus may detect that transmission or reception of a first packet using a first RAT will overlap in time with reception of a second packet using a second RAT. The apparatus prioritizes the first packet or the second packet based at least on a relative priority of the first packet and the second packet.

Abstract: Certain aspects of the present disclosure provide techniques for mapping two-stage sidelink control with multiple layer sidelink data channel. A first user equipment (UE) can rate-match a multiple-layer second stage of a two-stage sidelink control information (SCI) transmission as a single layer. The first UE transmits the multiple-layer second stage of the two-stage SCI, to a second UE, using multiple antenna ports.

Abstract: Embodiments include systems and methods for sidelink communications. In embodiments, a processor of a wireless device may determine signal strength information and priority information associated with a sidelink communication resource. The processor may determine coordination information based on the determined signal strength information and priority information. The processor may generate a message to include the determined coordination information. The processor may transmit the generated message including the determined coordination information to a second wireless device. In some embodiments, the generated message may be a control message, such as a medium access control control-element (MAC-CE) or a sidelink control information message.

Abstract: Methods, systems, and devices for wireless communication are described. One method for wireless communication at a first device includes receiving a multicast packet from a second device, decoding control header information in the received multicast packet, determining that a decoding procedure associated with a payload of the received multicast packet is unsuccessful and transmitting a negative acknowledgement (NACK) based at least in part on the determining. The method also includes retrieving a list of transmitter identifiers. In some cases, transmitting the NACK is based at least in part on the list of transmitter identifiers. The method further includes determining a transmitter identifier associated with the multicast packet and determining that the transmitter identifier is present in the list of transmitter identifiers.

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: 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may receive, on a sidelink and from a second wireless communication device, resource reservation information associated with the second wireless communication device. The resource reservation information may identify sidelink resources that are reserved for the second wireless communication device for transmission on the sidelink. The first wireless communication device may transmit, on the sidelink, the resource reservation information to a third wireless communication device. Numerous other aspects are provided.

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. Numerous other aspects are provided.
