Description

technical field

[0001] The present invention relates to a method for estimating the code power of an interference signal in a mobile communication system, more specifically, to a method for estimating the power of an interference signal by using an intermediate pilot received signal in a time division duplex code division multiple access system. Background technique

[0002] Time Division Duplex Code Division Multiple Access (TD-CDMA) is a wireless transmission technology scheme proposed by the third-generation mobile communication system standardization organization. It is designed for symmetrical and asymmetric third-generation mobile communication services in all wireless environments. of. Time-division duplex code-division multiple access can support flexible time-domain up / downlink switching on each radio frequency carrier. The time-domain adaptive resource allocation in the transmission direction can achieve the best utilization rate of the spectrum allocation indepen...
