An explicit indication is provided regarding whether information was subjected to interference during transmission. For example, a receiver can monitor received packets and determine whether any of data units in a given received packet were subjected to interference during transmission. If so, the receiver can send an indication to the transmitter to inform the transmitter of the interference. This indication enables the transmitter to distinguish between packet loss that occurred as a result of channel fade and packet loss that occurred as a result of interference. Consequently, the transmitter is able to invoke different actions depending on whether the packet loss is due to channel fade or interference. |
