Methods, systems, and devices for enhanced negative acknowledgment control (NAC) frame are described. A device may generate and communicate an enhanced NAC frame that includes additional error information to indicate to the device a cause for the error. The device may receive a data frame and determine an error condition associated with a set of layers of a protocol stack. The device may generate feedback indicating a cause for the determined error condition and transmit the feedback indicating the error cause. The feedback may be a NAC that includes a first quantity of bits configured for indicating an existence of an error and a second quantity of bits configured for indicating the error cause. A format of the NAC frame may include bits configured to identify multiple types of error causes associated with the different layers of the protocol stack.
