论文摘要
由于其相互的传播特性，动态时分层双工（TDD）被认为是5G新无线电的重要传输技术。但是，潜在的交联干扰（CLI）对动态-TDD系统中超可靠和低潜伏期通信（URLLC）的可行性施加了基本限制。在这项工作中，我们提出了使用正交空间投影的近乎最佳和复杂性有效的CLI抑制方案，而在后空链路上，信号传导限制在B-Bit中。与最先进的动态-TDD研究相比，提出的解决方案可显着改善URLLC停电延迟，例如-199％的降低，同时将URLLC数据包的可实现能力提高 +156％。
Dynamic time division duplexing (TDD) is envisioned as a vital transmission technology of the 5G new radio, due to its reciprocal propagation characteristics. However, the potential cross-link interference (CLI) imposes a fundamental limitation against the feasibility of the ultra-reliable and low latency communications (URLLC) in dynamic-TDD systems. In this work, we propose a near-optimal and complexity-efficient CLI suppression scheme using orthogonal spatial projection, while the signaling overhead is limited to B-bit, over the back-haul links. Compared to the state-of-the-art dynamic-TDD studies, proposed solution offers a significant improvement of the URLLC outage latency, e.g., -199% reduction, while boosting the achievable capacity per the URLLC packet by +156%.
