Methods, systems, and devices for wireless communications are described. A wireless communication device may implement a radio link control (RLC) early retransmission procedure based on triggering criteria. The triggering criteria may include a threshold quantity of hybrid automatic repeat request retransmissions or a threshold remaining delay budget for a packet. When the criteria are satisfied for a given packet, the transmitting wireless communication device may start a timer. If the timer expires, the transmitting wireless communication device may perform an RLC retransmission of the packet. If the timer has a non-zero duration, the transmitting wireless communication device may transmit a polling request. The timer may be stopped when the transmitting wireless communication device receives a status report in response to the polling request or when the timer expires. If the status report indicates a negative acknowledgment for the packet, the transmitting wireless communication device may retransmit the packet.
