In this paper, we study the design and development of the system level simulation platform of TD-SCDMA, mainly introducing the design of power control simulation algorithms in multi-carrier cell mode which support mixed service model of UEs. The theory of power control by adaptive integer step-size is described in detail, and the simulation results in TD-SCDMA system level simulation platform with practical examples are analyzed. Taking simulation of power control by our way has certain practical significance.
