A network node (10) which supports EGPRS, the network node (10) being arranged (11, 13) to transmit RLC data blocks to at least one other network node in the EGPRS system and to receive acknowledgments from the other network node for successfully received RLC data blocks. The network node is also arranged to make pre-emptive retransmissions of unacknowledged previously transmitted RLC data blocks, and to make its transmissions with or without precoding. The network node (10) is arranged (11, 13, 14) to use precoding for a first percentage of the pre-emptive retransmissions and for a second percentage of the transmissions of RLC data blocks that have not been transmitted previously. |
