Implementation of ARQ on gnuradio

Hi, Guys,
I notice there is a lot of implementation of ARQ on gnuradio, like
Re: [Discuss-gnuradio] MAC layer development and USRP2
[Discuss-gnuradio] Data transmission in bursts using uhd
[Discuss-gnuradio] Anyone successfull on Transciever Function of RFX2400

I am working on writing a ARQ on uhd interface.
I wonder if there are open sources code about ARQ on previous version
of gnuradio. Or some friends are willing to share the codes. So I can
upgrade it to uhd version.
Thanks.

Here’s a little info on a simple ARQ implementation. Moritz create a
nice
sliding window ARQ that I have not merged yet.
