Techniques for reducing feedback time for communications over multiple wireless connections

Methods, systems, and devices for wireless communication that support entry into a fast negative acknowledgement (NACK) mode are described. A user equipment (UE) may enter a fast NACK mode and may reduce the value of a respective timer for one or more wireless connections (e.g., may independently cover the timer for each connection). The timer may be referred to as retransmission request duration. If two or more component carriers (CCs) are configured, the UE may determine a value of the timer based on locations of data holes within the two or more CCs. Based on entering the fast NACK mode, the UE may cover the configured timers for the respective wireless connections with new shorter timers. Based on expiration of the new timer, the UE may transmit an RLC NACK to the base station via the corresponding wireless connection. 描述了支持进入快速否定确认(NACK)模式的用于无线通信的方法、系统和设备。用户设备(UE)可进入快速NACK模式，并可减小用于一个或多个无线连接的相应定时器的值(例如，可针对每个连接独立地覆盖该定时器)。该定时器可被称为重传请求持续时间。如果配置有两个或更多个分量载波(CC)，则该UE可基于该两个或更多个CC内的数据孔洞的位置来确定该定时器的值。基于进入该快速NACK模式，
