The invention discloses a method for dynamic channel allocation in TDD-CDMA mobile communication system. Based on the distance between mobile station and subzone base station BS, mobile stations MS are classified. Code tract in same group of code track (carrier frequency + time slot) is allocated to the mobile station with nearer distance. MS with different distances have different requirements of emission power. Whether crossed time slot code track group can be used or not, and use of group of code track with what kind of multiplexing factor need to be determined.
