Kertas kerja ini mencadangkan skim pemultipleksan berasaskan pembawa tunggal (SC) yang cekap untuk isyarat kawalan Lapisan 1 (L1)/Lapisan 2 (L2) dalam capaian radio SC-FDMA menggunakan DFT-Spread OFDM dalam pautan atas UTRA Evolved. Isyarat kawalan L1/L2 diperlukan untuk teknik akses paket utama seperti penjadualan pautan bawah, penyesuaian pautan, permintaan ulangan automatik hibrid (ARQ) dengan gabungan lembut dan untuk isyarat kawalan maklum balas pautan atas. Kami mula-mula mencadangkan skim pemultipleksan berasaskan SC untuk isyarat kawalan L1/L2 dalam saluran data kongsi untuk set peralatan pengguna (UE) yang menghantar kedua-dua saluran data kongsi uplink dan isyarat kawalan L1/L2 dalam subframe yang sama. Kami juga mencadangkan skim pemultipleksan untuk isyarat kawalan L1/L2 tanpa penghantaran data pautan atas yang memanfaatkan lompat frekuensi intra-subframe (FH) menggunakan berbilang blok sumber frekuensi masa (RB) yang diperuntukkan secara eksklusif untuk mendapatkan keuntungan kepelbagaian frekuensi. Tambahan pula, kami mencadangkan skim pemultipleksan berasaskan CDMA ortogon menggunakan anjakan kitaran jujukan korelasi automatik sifar amplitud malar (CAZAC) untuk isyarat kawalan L1/L2 daripada UE yang berbeza dalam RB frekuensi masa jalur sempit yang sama. Keputusan simulasi komputer menunjukkan bahawa skim pemultipleksan berasaskan SC yang dicadangkan untuk isyarat kawalan L1/L2 dalam saluran data kongsi mencapai daya pemprosesan pengguna yang lebih tinggi daripada skim pemultipleksan berasaskan multicarrier. Keputusan juga menunjukkan bahawa skim pemultipleksan yang dicadangkan untuk isyarat kawalan L1/L2 yang memanfaatkan FH intra-subframe untuk UE tanpa penghantaran data pautan atas mencapai penerimaan berkualiti tinggi melalui perolehan kepelbagaian frekuensi yang besar. Tambahan pula, kami menunjukkan bahawa pemultipleksan CDMA ortogon berasaskan anjakan kitaran yang dicadangkan adalah berkesan dalam pemultipleksan berbilang isyarat kawalan L1/L2 daripada UE yang berbeza dalam RB yang sama.

Abstract: This paper proposes efficient single-carrier (SC) based multiplexing schemes for Layer 1 (L1)/Layer 2 (L2) control signals in SC-FDMA radio access using DFT-Spread OFDM in the Evolved UTRA uplink. L1/L2 control signals are necessary for key packet access techniques such as downlink scheduling, link adaptation, hybrid automatic repeat request (ARQ) with soft combining, and for uplink feedback control signals. We first propose a SC-based multiplexing scheme for L1/L2 control signals within a shared data channel for a set of user equipment (UE) that transmits both an uplink shared data channel and L1/L2 control signals within the same subframe. We also propose a multiplexing scheme for L1/L2 control signals without uplink data transmission that takes advantage of intra-subframe frequency hopping (FH) using multiple exclusively-assigned time-frequency resource blocks (RBs) to obtain a frequency diversity gain. Furthermore, we propose an orthogonal CDMA-based multiplexing scheme using cyclic shifts of a constant amplitude zero auto-correlation (CAZAC) sequence for L1/L2 control signals from different UEs within the same narrowband time-frequency RB. Computer simulation results show that the proposed SC-based multiplexing scheme for the L1/L2 control signals within the shared data channel achieves a higher user throughput than a multicarrier-based multiplexing scheme. The results also show that the proposed multiplexing scheme for the L1/L2 control signals that takes advantage of the intra-subframe FH for the UE without uplink data transmission achieves high quality reception through large frequency diversity gain. Furthermore, we show that the proposed cyclic-shift based orthogonal CDMA multiplexing is effective in the multiplexing of multiple L1/L2 control signals from different UEs within the same RB.
