More precisely, compressed bitmaps (decoding) are supported for DL TBFs only, since it is required to decode them DL Ack/Nack if the window size is increased which makes sense with multiple PDCH. > The reason > is because we want to avoid bufferbloat our windows don't really get that big and > it seems we didn't need it yet. The reason for not implementing them for UL TBF ACK yet was the fact that we only support single slot only in that direction and that the imposed restriction won't probably hurt in most cases. We can still send URBB even if the window size were larger than 96, so there are only some cases with long runs of NACKs and very few ACKs which might suffer from a slightly increased latency. > Now that you have built a tree based encoder, it > might make sense to include the encoder, add tests for the encoding, reason/explain > the performance and then hook the encoding in the DL ACK handling. -> UL TBF ACK handling Jacob
