Abstract
A method for compact representation of multi-code signaling that includes determining a number of multi-codes and a code offset. A codeword is formulated that includes a code group indicator and an offset indicator. The codeword represents a compact representation of multi-code signaling and is formulated and may be decoded without the need for a look-up table.
