Title : | Cell-Free mMIMO Systems with Dynamic TDD |
Authors : | Hanwoong Kim, Hakkeon Lee, Taehyung Kim, and Daesik Hong |
Conference : | IEEE VTC Spring 2022 |
Abstract : | Cell-free massive multi-input multi-output (CF-mMIMO) systems assume that a single central processing unit (CPU) communicates with a large number of user equipments (UEs) using the same time-frequency resources. However, allocating the same frame configuration to all the UEs makes it difficult to meet the traffic demands of each individual UE. In this paper, we propose using dynamic-time division duplex (D-TDD) in CF-mMIMO systems. To mitigate the cross-link interference (CLI), we propose a new UE-grouping algorithm. Simulation results show that the implementation of D-TDD reduces the median value of the UL packet delay and the DL packet delay by up to 75% and 30% respectively. Furthermore, the proposed UE-grouping reduces the average packet delay by 50% compared to static-TDD (S-TDD). |
