- Abstract
Carrier aggregation (CA) technology is one of key technologies in LTE-Advanced(LTE-A) system. UE can aggregate multiple component carriers (CCs) as a wider band to support the demand of higher data rates and improve the spectrum utilization. When terminal aggregates multiple downlink carrier components at the same time, LTE-A terminal needs to be feedback 20 HARQ-ACK bits at most, so that LTE-A system adds PUCCH format3.This paper presents an efficient method for feeding back large downlink HARQ information to support a variety of terminals with different bandwidth capacity.
