Antara lima senario penggunaan pengagregatan pembawa (CA), senario yang paling disukai ialah Senario 1, yang memaksimumkan keuntungan CA dengan menindih sepenuhnya sel primer (PCell) dan satu atau lebih sel sekunder (SCells). Ia mungkin kerana jalur frekuensi yang sama digunakan antara pembawa komponen (CC) jadi liputan yang hampir sama dijangka. Walau bagaimanapun, Senario 1 tidak dapat menjamin daya pemprosesan yang tinggi dalam pengagregatan pembawa teknologi capaian berbilang radio (CA berbilang RAT) yang sedang dikaji secara aktif. Ciri frekuensi pembawa yang berbeza dalam CA berbilang RAT menyukarkan untuk memadankan julat frekuensi yang berbeza dengan tepat. Jika julat PCell dan SCell berbeza, daya pemprosesan yang tinggi mungkin tidak diperolehi walaupun operasi CA. Kami mendapati ketidakpadanan liputan kira-kira 37% antara PCell dan SCell dalam rangkaian yang digunakan dan menyedari pengurangan keuntungan CA di kawasan tersebut. Dalam kertas kerja ini, kami mencadangkan pendekatan perubahan PCell baru bernama "Pensuisan frekuensi PCell (PFS)" untuk menjamin daya pemprosesan yang tinggi terhadap ketidakpadanan liputan sel dalam senario penggunaan CA berbilang RAT 1. Keputusan eksperimen menunjukkan bahawa daya pemprosesan meningkat sebanyak 9.7% secara purata dan terutamanya sebanyak 80.9% di sekitar kawasan pinggir sel apabila PFS digunakan dan bukannya operasi penyerahan CA warisan.

Abstract: Among the five carrier aggregation (CA) deployment scenarios, the most preferred scenario is Scenario 1, which maximizes CA gain by fully overlapping a primary cell (PCell) and one or more secondary cells (SCells). It is possible since the same frequency band is used between component carriers (CCs) so nearly the same coverage is expected. However, Scenario 1 cannot guarantee high throughput in multi-radio access technology carrier aggregation (multi-RAT CA) which is actively being researched. Different carrier frequency characteristics in multi-RAT CA makes it hard to accurately match different frequency ranges. If the ranges of PCell and SCell differ, high throughput may not be obtained despite the CA operation. We found a coverage mismatch of approximately 37% between the PCell and SCell in the deployed network and realized a reduced CA gain in those areas. In this paper, we propose a novel PCell change approach named “PCell frequency switching (PFS)” to guarantee high throughput against cell coverage mismatch in multi-RAT CA deployment scenario 1. The experiment results show that the throughput increased by 9.7% on average and especially by 80.9% around the cell edge area when PFS is applied instead of the legacy CA handover operation.
