1. A method, comprising:
transmitting two or more information code blocks (CBs) in a broadcast, multicast or groupcast transmission to a plurality of intended receiving nodes, wherein each of the two or more information CBs includes a respective set of information bits and a respective CB-specific check block encoded from the respective set of information bits;
generating one or more cross-CB check blocks, each cross-CB check block generated by combining at least two subsets of one or more bits each, each of the at least two subsets being a respective subset of bits of a respective one of at least two of the information CBs; and
transmitting at least one of the one or more cross-CB check blocks in another broadcast, multicast or groupcast transmission to two or more of the intended receiving nodes.
