Sistem antena teragih berskala besar (LS-DAS) semakin meningkat minat dan muncul sebagai calon yang sangat menjanjikan untuk komunikasi wayarles masa hadapan. Untuk meningkatkan kualiti perkhidmatan (QoS) pengguna dalam sistem ini, kajian ini mencadangkan pendekatan pengelompokan bantuan kerjasama pengguna berdasarkan seni bina berpusatkan peranti; ia membolehkan penghantaran berbilang input berbilang pengguna berbilang-output dengan persediaan bukan timbal balik. Kami secara aktif menggunakan teknik komunikasi peranti-ke-peranti untuk mencapai perkongsian maklumat pengguna dan cuba membentuk kelompok di sebelah pengguna dan bukannya cara tradisional yang melakukan pengelompokan di sebelah stesen pangkalan (BS) dalam pemuatan data. Kami seterusnya mengguna pakai seni bina tertumpu peranti untuk memecahkan had struktur selular BS-centric klasik. Selain itu, kami memperoleh ungkapan anggaran untuk mengira kadar pengguna untuk LS-DAS dengan penggunaan prapengekodan paksaan sifar dan pertimbangan gangguan antara kelompok. Keputusan berangka menunjukkan bahawa ungkapan anggaran meramalkan kadar pengguna dengan kos pengiraan yang lebih rendah daripada yang ditunjukkan oleh simulasi komputer, dan pendekatan yang dicadangkan memberikan pengalaman pengguna yang lebih baik untuk, khususnya, pengguna yang mempunyai QoS yang tidak boleh diterima.

Abstract: Large-scale distributed antenna systems (LS-DASs) are gaining increasing interest and emerging as highly promising candidates for future wireless communications. To improve the user's quality of service (QoS) in these systems, this study proposes a user cooperation aided clustering approach based on device-centric architectures; it enables multi-user multiple-input multiple-output transmissions with non-reciprocal setups. We actively use device-to-device communication techniques to achieve the sharing of user information and try to form clusters on user side instead of the traditional way that performs clustering on base station (BS) side in data offloading. We further adopt a device-centric architecture to break the limits of the classical BS-centric cellular structure. Moreover, we derive an approximate expression to calculate the user rate for LS-DASs with employment of zero-forcing precoding and consideration of inter-cluster interference. Numerical results indicate that the approximate expression predicts the user rate with a lower computational cost than is indicated by computer simulation, and the proposed approach provides better user experience for, in particular, the users who have unacceptable QoS.
