LTE-A system introduces new PUCCH format 3, so UE can feedback up to 20 bits, the downlink ACK/NACK. Because of the limitation of bits, PUCCH format 3 can't use regular RM code, but use two way of RM code. This paper first introduces two methods of normal RM and overlapping RM, and then analysis the simulation of the performance of different algorithms that overlap RM has the better bit error rate and throughput performance.
