I had a quick look at 12.21 and there doesn't appear to be anything for the AGCH. So we will need to calculate the size from the channel configuration but this should be fairly easy. The other topic is the question of fairnes? The first requests will fill the queue, and then we drop most of the requests. Can you implement the size calculation?
