Abstract
A method and apparatus for detecting discontinued transmission (DTX) frames in data frames received over a link or channel, is described, where a DTX frame is a frame that does not carry data and which is transmitted with zero power over the link or channel. The method and apparatus determines whether a received data frame is a DTX frame based on a plurality of metrics. Based on the metrics, the method and apparatus may effectively discriminate a case where a data frame is received as an erasure (e.g., data frame received with errors), and a case where a transmitted data frame is received as a DTX frame.
