摘要

5G新型双工演进技术将在TDD频谱上引入基站侧子带不重叠全双工制式，以迎合万物智联和工业互联网对低时延和大上行吞吐量同时提出的更高要求，同时还需要进一步研究并解决基站间交叉时隙干扰问题，使能公网和专网采用不同的TDD上下行时隙配比的组网方式。为满足5G新型双工演进技术的未来部署需求，对TDD宏微异时隙组网和子带不重叠全双工制式的潜在部署场景和相关干扰特征进行了分析和研究，提出潜在可行的干扰抑制方案，并通过链路预算、仿真评估和样机验证等形式论证了技术可行性。

Abstract

Subband non-overlapping full duplex (SBFD) at gNB side within a conventional TDD band was considered as a key feature of 5G-Advanced to fulfill the challenging requirements of low latency and high uplink throughput emerging in vertical industry and industrial internet.Meanwhile

gNB-to-gNB cross-link interference handling needed to be enhanced to enable different TDD configurations for both public network (Macro) and vertical network (Micro) applied in the same frequency band.With a thorough analysis on the interference characteristic in the potential deployment scenarios for both different TDD configurations and subband non-overlapping full duplex

various feasible interference handling schemes to fulfill the challenging deployment requirements for vertical industry and industrial internet were presented

and the feasibility of above duplex enhancement schemes was checked via link budget

simulation and proof-of-concept prototype.
