Abstract: A first user equipment (UE) receives sidelink resource reservation information over sidelink from one or more UEs. The first UE transmits inter-UE coordination information in a sidelink transmission based on a probability threshold being met. A wireless device may receive one or more of a status of a UE, a capability of the UE, or a report. The wireless device may configure the UE with a probability threshold for transmission of inter-UE coordination information in a sidelink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. To improve sidelink reservation schemes. a first user equipment (UE) may indicate its preferences for sidelink resources to a second UE that may select sidelink resources for sidelink messages based on the indicated preferences. For example, the first UE may monitor a first set of sidelink resources for sidelink control information (SCI) to determine which sidelink resources of a second set of sidelink resources are available. Based on the monitoring, the first UE may generate a bitmap that indicates the first UE's preferences for the sidelink resources of the second set and may transmit a coordination message to the second UE that includes the bitmap. The second UE may receive the coordination message and transmit, to the first UE, one or more sidelink messages using one or more sidelink resources of the second set selected based on the indicated preferences.

Abstract: Certain aspects of the present disclosure provide techniques for determining priority information associated with hybrid automatic repeat request (HARQ) feedbacks for wireless nodes in sidelink communications. A subset of the HARQ feedbacks are selected based on the priority information. The selected HARQ feedbacks are then transmitted to the second wireless nodes.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first sidelink control information (SCI) from a second UE and a second SCI from a third CE, the first SCI may indicate a first set of resources and the second SCI may indicate a second set of resources that at least partially overlap with the first set of resources. The sets of resources may indicate resources reserved by the UEs for sidelink communications. The first UE may measure a first received power associated with the second UE or a second received power associated with the third UE, or both, based on the overlap and may transmit, to the second UE and/or the third UE, an indication of a conflict based on the first received power and/or the second received power satisfying a condition.

The method also includes receiving, at the first UE from the second UE, a RRC setup message that includes a second DRX preference at the second UE. The method further includes transmitting, from the first UE to the second UE, a RRC setup complete message that includes an indication of a confirmed DRX cycle.

Abstract: Methods, systems, and devices for wireless communications are described. To improve sidelink reservation schemes, a first user equipment (UE) may receive, from a second UE, a coordination message indicating a set of resources associated with sidelink communications and a preference of the second UE for one or more subsets of the set of resources. The first UE may transmit the sidelink communications using one or more resources of the set of resources based on the preference of the second UE for the one or more subsets of the set of resources. In some examples, the one or more resources may be selected from candidate resources within a resource selection window of the first UE. Additionally, or alternatively, the candidate resources may be based on the preference of the second UE.

The coordination message may include the resource reservation information for the second V2X device associated with the first RAN. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A receiver user equipment (UE) may communicate with a transmitter UE in a sidelink channel to report a congestion index to the transmitter UE and/or additional transmitter UEs, where the transmitter UE(s) may then adjust one or more sidelink operation parameters based on the reported congestion index. In some cases, the transmitter UE may report the congestion index to an upper layer, to other transmitter UEs, to application layers, or a combination thereof. The transmitter UEs 115 and/or application layer may then adjust one or more sidelink transmission operation parameters based on the reported congestion index. For example, the transmitter UEs and/or application layer may adjust threshold values to lessen a number of retransmissions and lessen congestion.
