LTE-TDD interference analysis in spatial, time and frequency domain

The traffic of the small cell has a characteristic of the bursty and time varying, it is advantageous to allocate of TDD with a variable DL/UL traffic rate characteristic. However, the existing standard is limitation in the utilization of DL and UL resources, which is considering the instantaneous traffic situation of the cell. With that case, 3GPP standardized TDD eIMTA for supporting the dynamic setting of the DL/UL configuration of the TDD cell. In this paper, based on the target scenarios considered in the TDD eIMTA WI, we obtained the coexistence criterion information of Multidimensional domain including time, space and frequency domain between mobile communication services based on LTE-TDD. We also proposed a DL/UL configuration guideline for stable establishment of LTE-TDD service through calculation of acquisition available communication capacity.
