摘　　要：TD-MBMS is the abbreviation of time division-synchronous code division multiple access （TD-SCDMA） multimedia broadcast and multicast service （MBMS）,which was introduced in the release 6 of universal mobile telecommunications system （UMTS） in order to deliver multimedia data more efficiently. Since TD-MBMS may work on the same time slot （TS） of the same frequency with TD-SCDMA and time division-high speed downlink packet access （TD-HSDPA） as described in the unified timeslot networking （UTN） strategy,the work of co-existing interference analysis is an important research filed. This article firstly analyzes theoretically the co-existing interference between TD-MBMS and TD-SCDMA/TD-HSDPA. Then,system level simulation is used to quantify the co-existing interference under different scenarios considering the transmit power of TD-MBMS and TD-HSDPA and the load factor of TD-SCDMA network. Simulation results show that TD-SCDMA/TD-HSDPA has little impact on the TD-MBMS while the interference from TD-MBMS to TD-SCDMA/TD-HSDPA is more serious and the corresponding isolation distance is then suggested. The results are useful for radio network planning and optimization of TD-SCDMA.TD-MBMS is the abbreviation of time division-synchronous code division multiple access （TD-SCDMA） multimedia broadcast and multicast service （MBMS）,which was introduced in the release 6 of universal mobile telecommunications system （UMTS） in order to deliver multimedia data more efficiently.
