Inter-UE coordination signaling for sidelink communications

Apparatus and systems for inter-UE coordinated feedback for sidelink communications are described. Specifically, inter-UE coordination feedback signaling for reliable sidelink communications is described, including signaling of transmitter-based resource allocation and conflicts, prioritization of inter-UE coordination feedback, and timing of inter-UE coordination feedback. Sidelink hybrid acknowledgement request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) or NACK-only signaling is prioritized over half-duplex (HD) or common channel collision (CC) feedback indications, and uplink transmissions are prioritized over sidelink transmissions. In response to detecting the collision, the inter-UE coordination feedback is transmitted relative to a time slot in which an HD or CC event occurs or a reserved time slot relative to resources in which a sidelink transmission occurs. 描述了用于侧链路通信的UE间协调反馈的装置和系统。具体地，描述了用于可靠的侧链路通信的UE间协调反馈信令，包括：基于发送器的资源分配和冲突的信令，UE间协调反馈的优先级排序，以及UE间协调反馈的定时。侧链路混合确认请求(HARQ)确认/否定确认(ACK/N
