查询词典 at the distance

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.

本发明公开了一种TDD－CDMA移动通信系统的动态信道分配方法，是将移动台MS按照与本小区基站BS的距离进行分类，同一个码道组中的码道分配给距离相近的移动台MS；同时不同距离的MS对发射功率的要求不同，对相邻小区的干扰也不同，系统根据MS对发射功率的要求，确定其是否可以使用交叉时隙码道组和使用哪种复用因子的码道组。

There is a positive relationship between the degree of knowledge tacitness and transfer cost; there is a negative relationship between the degree of knowledge overlap and transfer cost; there is a positive relationship between the degree of physics distance and transfer cost, but the relationship is not that significant; there is a positive relationship between the hierachical distance and transfer cost; there is a negative relationship between the trust and transfer cost.
