Resource allocation with collision indication for sidelink communications

Certain aspects of the present disclosure provide techniques for resource allocation with collision indication for sidelink communications. A method, which may be performed by a first user equipment (UE), includes receiving, from a second UE, a first sidelink transmission indicating a first resource reservation; receiving, from a third UE, a second sidelink transmission indicating a second resource reservation; and transmitting feedback to at least the second UE, the feedback comprising: Hybrid Automatic Repeat Request (HARQ) feedback with respect to the first sidelink transmission; and an indication of whether the first UE detects a conflict between the first resource reservation and the second resource reservation. 本公开的某些方面提供了用于侧链路通信的具有冲突指示的资源分配的技术。一种可以由第一用户设备(UE)执行的方法包括：从第二UE接收指示第一资源预留的第一侧链路传输；从第三UE接收指示第二资源预留的第二侧链路传输；以及向至少第二UE发送反馈，该反馈包括：关于第一侧链路传输的混合自动重传请求(HARQ)反馈；以及第一UE是否检测到第一资源预留与第二资源预留之间的冲突的指示。
