In one embodiment of the method, a channel quality metric for a first subframe is estimated based at least in part on a channel quality metric for a previous subframe, and a channel quality metric for a second subframe is estimated based at least in part on the channel quality metric for the previous subframe. Here, the second subframe is later in time than the first subframe. Then, a channel quality metric for a time slot located between the first and second subframes is estimated based on the channel quality metrics for the first and second subframes.
