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..
