Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support chained sidelink transmissions. A transmitting user equipment (UE) may send, to a receiving UE, sidelink control information (SCI) that reserves resources for transmission from the transmitting UE as well as reserves resources for a response transmission from the receiving UE. The receiving UE may respond with a transmission using the resources that were reserved in the SCI and without sending its own SCI to reserve resources for the response. The latency between the transmitting UE sending the first transmission and receiving a response from the receiving UE may be reduced, because the transmitting UE reserved the resources for itself and the receiving UE with the same SCI.
