A method of coding control blocks for packet communication wherein the code for control information is restricted to a smaller subset of the coding set used for data blocks. The smaller subset has the property that subfields within the field of the block can be recognized and decoded without the remainder of the encoded block having been received. An 8B/10B code, consisting of 3B/4B and 5B/6B subfields, has the required property. In packet communication, the recognition in an early control subfield that the packet is to be retransmitted allows bit-by-bit retransmission of the encoded packet with only the early subfield being processed.
