In this paper, the thought of space division full duplex (SDFD) is introduced to improve the flexibility of traffic adaptation in time division duplex (TDD) systems. In SDFD scheme, two spatial separated transmission points (TPs), which can be two base stations (BSs), serve downlink (DL) and uplink (UL), respectively. In this case, the interference between two TPs cannot be avoided, which might affect the performance of the TDD system. Therefore, this paper proposes scheduling method for flexible transmission in TDD systems. Different from the original SDFD scheme, the TPs are not designated in advance. DL and UL TP selection algorithms are proposed to mitigate the inter-TP interference. Compared with previous studies in TDD systems with half duplex transmission, the proposed scheduling method and TP selection algorithms can improve the system performance dramatically.
