In Advanced Long Time Evolution (LTE-A) mobile wireless communication system, the Carrier Aggregation (CA) technique feature was introduced to support large transmission bandwidth. But due to the capacity limit of UE, to measure all component carriers with low latency and cost has been a challenge. In this paper a solution is presented in which only some reference component carriers need to be measured; the signal strength of others are estimated by utilizing the correlation between these component carriers and reference component carrier. The simulation results show that the estimation error is acceptable.
