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.
Claims20
A method, comprising:
- transmitting two or more information code blocks (CBs) to a plurality of intended receiving nodes;
- generating one or more cross-CB check blocks, 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;
- and
- transmitting at least one of the one or more cross-CB check blocks to at least one of the intended receiving nodes.
An apparatus comprising a processing unit, the processing unit being configured to execute machine-readable instructions to cause the apparatus to:
- transmit two or more information code blocks (CBs) to a plurality of intended receiving nodes;
- generate one or more cross-CB check blocks, 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;
- and
- transmit at least one of the one or more cross-CB check blocks to at least one of the intended receiving nodes.
A computer readable medium having machine-executable instructions stored thereon, wherein the instructions, when executed by a processing unit of an apparatus, cause the apparatus to:
- transmit two or more information code blocks (CBs) to a plurality of intended receiving nodes;
- generate one or more cross-CB check blocks, 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;
- and
- transmit at least one of the one or more cross-CB check blocks to at least one of the intended receiving nodes.
