Abstract
Methods and systems for two-dimensional (2D) coding are described for broadcast, multicast or groupcast applications. Two or more information code blocks (CBs) are transmitted to a plurality of intended receiving nodes. One or more cross-CB check blocks are generated, each cross-CB check block being generated based on a set of cross-CB bits, the set of cross-CB bits including at least one bit selected from each of at least two of the information CBs. At least one cross-CB check block is transmitted to at least one of the intended receiving nodes.
