Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support enhanced scheduling request configurations. A user equipment (UE) may obtain, at a packet data convergence protocol (PDCP) layer of the UE, information associated with a data packet for transmission by the UE. The UE may transmit a scheduling request that indicates information regarding an elapsed time period since the information associated with the data packet was obtained at the PDCP layer of the UE, or whether the data packet is a final packet of a set of data packets, or both. A network entity may receive the scheduling request and determine scheduling information for uplink communications by the UE based on the information regarding the elapsed time period, or whether the data packet is the final data packet, or both. The network entity may transmit the scheduling information to the UE.
