我们考虑一个全双工（FD）多用户多输入多输出（MIMO）系统，其中基站（BS）同时为多个上行链路（UL）和下行链路（DL）用户服务。我们解决了服务质量（QoS）问题，其中BS和UL用户的传输和功率在系统的每个用户的最小速率约束下最小化。我们首先提出了一个基于顺序凸规划（SCP）的集中式解决方案，然后提出了一个使用节点之间交换的干扰价格来表示接收干扰成本的分布式解决方案。通过数值模拟对所提出的设计进行了评估。
We consider a full-duplex (FD) multiuser multiple-input multiple-output (MIMO) system where the base-station (BS) serves multiple uplink (UL) and downlink (DL) users simultaneously. We address the quality-of-service (QoS) problem in which the transmitted sum-power at the BS and UL users is minimized subject to minimum rate constraints at each user of the system. We first propose a centralized solution based on sequential convex programming (SCP), and then propose a distributed solution by using interference prices exchanged among the nodes to represent the cost of received interference. The proposed designs are evaluated via numerical simulations.
