摘要： Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support hybrid automatic repeat request (HARQ) schemes to improve the likelihood that information is received correctly over a wireless communications link. In HARQ, when a transmitting device determines that a receiving device failed to successfully decode a transmission of information, the transmitting device may retransmit the information to the receiving device. In some cases, HARQ techniques may be used for communications associated with different types of services. In such cases, to keep the latency of communications within a latency budget for a particular type of service, wireless devices may utilize the techniques described herein to dynamically terminate HARQ retransmissions. For instance, a transmitting device may avoid retransmitting information when an amount of time that has elapsed since an original transmission of the information has exceeded the latency budget.
