摘要：With the purpose of satisfying what is required for future IMT Advanced mobile systems, 3GPP presented carrier aggregation (CA) in its latest LTE-Advanced criterions. Although carrier aggregation permits accumulation of carrier components (CCs) disseminated inside and transversely in different bands (intra/inter-band) along with CCs grouping possessing different bandwidths, the expectation is that the carrier aggregation provides a commanding improvement to the user throughput in LTE-Advanced (LTE-A). CA will permit the achievement of the target peak data rates in excess of 1 Gbps in the downlink and 500 Mbps in the uplink and the users has the right to use up to 100 MHz total of bandwidth. Nonetheless, the carrier aggregation (CA) introduced is mentioned in LTE Rel. 10, has essential changes from the baseline LTE Rel. 8 even though individual CC in LTE-A stays backwardly attuned with LTE Rel.8. This article offers carrier aggregation methods� review and the supported scenarios; subsequently necessities on radio resource management (RRM) functionality supporting CA. On-going research on the diverse algorithms supporting CA in LTE-Advanced are charted.
