Inter-cell interference in the UTRA-TDD (UMTS Terrestrial Radio Access-Time Division Duplex) system is investigated. There are some specific interference modes in the TDD mode. The inter-cell interference contains the interference caused by the adjacent cells and the interference caused by the adjacent channels. Some simulations are done to study the interference. Impacts of four different interference instances were taken into account in the simulations. Some interesting results are obtained from the simulations. Any little bit of asynchronism between the adjacent cells will affect the capacity of the uplink severely, which is mainly caused by the BS-BS interference. Two cells using the adjacent channels can be co-located at the same site if they are synchronized
