Abstract—Traffic in a small cell has characteristics of burst and time varying, and it is advantageous to allocate TDD having a variable Downlink(DL) / Uplink(UL) traffic rate characteristic. However, existing standards have limitations on the utilization of DL and UL resources considering the instantaneous traffic situation of the cell. Therefore, 3rd Generation Partnership Project (3GPP) standardized TDD eIMT supporting dynamic configuration of DL/UL configuration of TDD cell. In this paper, based on the target scenario considered in TDD eIMTA Work item (WI), coexistence criterion information is obtained through interference analysis in multi-dimensional domain including time, space domain between LTE-TDD based mobile communication services. We also proposed a DL/UL configuration guideline for stable establishment of LTE-TDD service through calculation of acquisition available communication capacity.
