Abstract
A scheme of error decoupling for carrier aggregation techniques to support a communication system is provided. The communication system operates with up to 2 codewords for up to 5 carriers, each codeword of each carrier having one acknowledgement/negative acknowledgement (ACK/NACK) or discontinuous transmission (DTX) to enable Hybrid Automatic Repeat reQuest (HARQ) to operate in each carrier. The scheme involves the steps of: performing separation of bits related to ACK, NACK, DTX for each carrier using up to 2 codewords; determining a maximum number of bits related to ACK, NACK, DTX when decoupling is not performed after a maximum number of carriers are used; and grouping the carriers such that separation between ACK, NACK, DTX of each carrier is optimized as long as the maximum number of bits is not exceeded.
