Kertas kerja ini mencadangkan skim pengumpulan peralatan pengguna (UE) dan menilai prestasi skim penjadualan untuk setiap kumpulan yang dibentuk dalam penerimaan berbilang-input berbilang-output (MIMO) kolaboratif. Dalam penyelidikan terdahulu, kriteria untuk pengumpulan UE dan kesan penjadualan kumpulan tidak pernah dibentangkan. Dalam skema kumpulan UE, dua kriteria, yang berorientasikan stesen pangkalan (BS) dan yang berorientasikan UE, dibentangkan. Skim carian penuh berorientasikan BS mencapai prestasi ideal walaupun ia memerlukan pengetahuan tentang kedudukan relatif semua UE. Oleh itu, skim carian tempatan berorientasikan UE juga dicadangkan. Sebagai skim penjadualan, penjadualan keadilan berkadar digunakan dalam peruntukan sumber untuk setiap kumpulan yang dibentuk. Apabila bilangan jumlah UE meningkat, perbezaan dalam bilangan UE antara kumpulan bertambah besar. Keputusan berangka yang diperoleh melalui simulasi komputer menunjukkan bahawa daya pengeluaran setiap pengguna meningkat dan keadilan di kalangan pengguna berkurangan apabila bilangan UE dalam sel meningkat dalam skim yang dicadangkan berbanding dengan skim konvensional.

Abstract: This paper proposes user equipment (UE) grouping schemes and evaluates the performance of a scheduling scheme for each formed group in collaborative multiple-input multiple-output (MIMO) reception. In previous research, the criterion for UE grouping and the effects of group scheduling has never been presented. In the UE grouping scheme, two criteria, the base station (BS)-oriented one and the UE-oriented one, are presented. The BS-oriented full search scheme achieves ideal performance though it requires knowledge of the relative positions of all UEs. Therefore, the UE-oriented local search scheme is also proposed. As the scheduling scheme, proportional fairness scheduling is used in resource allocation for each formed group. When the number of total UEs increases, the difference in the number of UEs among groups enlarges. Numerical results obtained through computer simulation show that the throughput per user increases and the fairness among users decreases when the number of UEs in a cell increases in the proposed schemes compared to those of the conventional scheme.
