Abstract

Inter-Tower Communication Network (ITCN), which supports communication between different base stations via wireless links, has excellent potential for simultaneous transmission of broadcast data and personalized data using Layered Division Multiplexing (LDM). In this paper, a heterogeneous ITCN architecture using LDM and wireless backhauling is proposed. In uplink transmission, the power-limited user devices transmit data to the secondary transmitters (STs), and the STs relay the data to the master transmitter (MT). In downlink transmission, the MT and multiple STs cooperatively transmit broadcast data using single frequency network (SFN) mode, and the STs relay the personalized data from the MT to users simultaneously. Considering the co-channel interference, this paper proposes a joint subchannel assignment and power allocation scheme for both uplink and downlink transmission. A mixed integer optimization problem is formulated, and an alternating optimization algorithm (AO) based on game theory and convex optimization is proposed. Simulation results are conducted with different system configurations to demonstrate the convergence and effectiveness of the proposed algorithms.

面向下一代融合通信广播系统的基于NOMA的异构网络传输体系结构

塔间通信网络（ITCN）通过无线链路支持不同基站之间的通信，具有利用分层分复用（LDM）同时传输广播数据和个性化数据的良好潜力。本文提出了一种基于LDM和无线回程的异构ITCN体系结构。在上行链路传输中，功率有限的用户设备将数据传输到二级发射机（STs），而二级发射机将数据中继到主发射机（MT）。在下行传输中，MT和多个st采用单频网络（SFN）模式协同传输广播数据，st同时将MT的个性化数据转发给用户。考虑到同信道干扰，本文提出了一种上下行传输的联合子信道分配和功率分配方案。提出了一个混合整数优化问题，并提出了一种基于博弈论和凸优化的交替优化算法。在不同的系统配置下进行了仿真，验证了算法的收敛性和有效性。

期刊介绍： The Society’s Field of Interest is “Devices, equipment, techniques and systems related to broadcast technology, including the production, distribution, transmission, and propagation aspects.” In addition to this formal FOI statement, which is used to provide guidance to the Publications Committee in the selection of content, the AdCom has further resolved that “broadcast systems includes all aspects of transmission, propagation, and reception.”
