Time division-long term evolution (TD-LTE) system and method for evaluating interference of TD-LTE system

Embodiments of the invention provide a time division-long term evolution (TD-LTE) system and a method for evaluating interference of the TD-LTE system. A remote radio unit of a time division-synchronous code division multiple access (TD-SCDMA) system is set to support a new working frequency band, and the new working frequency band is a working frequency band of the TD-LTE system which is upgraded from the TD-SCDMA system; one or a plurality of carriers of the TD-SCDMA system are adjusted to the working frequency band of the TD-LTE system, and all the TD-SCDMA carriers within the working frequency band of the TD-LTE system are ranked and numbered; all the TD-SCDMA carriers are set as test carriers according to an order from small to large of the serial numbers of all the TD-SCDMA carriers within the working frequency band of the TD-LTE system; an interference test is performed on each test carrier so as to acquire an interference on signal code power (ISCP) mean value of an uplink time slot of the test carrier in the test time; and whether the TD-LTE system is interfered is judged.
