Two main features of the MAC-hs protocol of HSDPA are retransmissions of erroneous blocks and in-sequence data delivery to the upper layer. The first function is fulfilled through the HARQ mechanism. The second function is achieved by managing transmitting/receiving window and by using a specific numbering. In this paper, the MAC-hs performance for different window sizes, timer’s values and number of retransmission attempts are studied. Simulations show that values of these parameters have to be carefully set up in order to prevent incorrect block discards at the receiver side.
