    摘要: To achieve the regulations of the IMT-Advanced, 3GPP utilizes the technology of
    carrier aggregation (CA) in LTE-A. Besides, 3GPP in the LTE Release-8 also advocates that
    people in the communications industry establish femtocells to reduce the loading of macrocells.
    However, HeNB is much more easily leads to the irregular establishment. Thus, this condition
    will bring about signal interference between base stations and user equipment (UE), which
    makes the whole carrier utility and throughput speed lower. Therefore, 3GPP proposes the
    approach of autonomous component carrier selection (ACCS), it would let every base station
    select the carrier which isn’t used by near base stations to avoid the carrier interference caused
    by the irregular establishment of HeNB. However, the selection rules of ACCS are imperfect
    and it will result in poor performance of system throughput and carrier utility and lower the
    connection of UE. In this paper, we propose a new ACCS based on user scheduling under the
    basic CA selection framework of ACCS. This method when the base station cannot be
    distributed carrier resources because of the interference, base station would check the current
    user equipment’s interference situation, UEs will be scheduled by interference situation, then the
    base station select the appropriate carrier distribution for UE in the schedule. Finally, simulation
    results show that method proposed by this study can raise resource distribution of main carrier to
    attain more users’ connection and simultaneously elevate the resource distribution of sub-carrier
    to meet the demands of UE bandwidth..
