Meeting the continued growth in data traffic volume, Dynamic Time Division\nDuplex (D-TDD) has been introduced as a solution to deal with the uplink (UL)\nand downlink (DL) traffic asymmetry, mainly observed for dense heterogeneous\nnetwork deployments, since it is based on instantaneous traffic estimation and\nprovide more flexibility in resource assignment. However, the use of this\nfeature requires new interference mitigation schemes capable to handle two\nadditional types of interference between cells in opposite transmission\ndirection: DL to UL and UL to DL interference. The aim of this work is to\nprovide a complete analytical approach to model inter-cell interference in\nmacro-cell and dense small-cell networks. We derive the explicit expressions of\nInterference to Signal Ratio (ISR) at each position of the network, in both DL\nand UL, to quantify the impact of each type of interference on the system\nperformance. Also, we provide the explicit expressions of the coverage\nprobability as functions of different system parameters by covering different\nscenarios. Finally, through system level simulations, we analyze the\nfeasibility of D-TDD implementation in both deployments and we compare its\nperformance to the static-TDD (S-TDD) configuration.\n
