Embodiment Construction

[0019] Because there are many implementation schemes for data services in mobile communications, for ease of understanding, a representative and generally applicable example—CDMA2000 proposal (made by 3GPP2) is used here to illustrate the rate control method proposed by the present invention. The invention is generally applicable to all applications having the essential features of this example.

[0020] Use formula (1) to calculate the load contribution of user i to active set sector j:

[0021] η i , j = 1 1 + W ( E b / N 0 ) ...

Abstract

The invention can efficiently assign and dispatch resources in real time between many service requests to improve speed control method and utilization of system resources.

Description

technical field [0001] The invention relates to a rate control method in a mobile communication system, especially for allocating transmission rates among service requests under different transmission conditions in a mobile communication system supporting multiple data transmission rates, so as to satisfy each requested service While improving the quality, improve the overall efficiency of the system. Rate control implements reasonable allocation and scheduling of resources by adjusting the rates allocated to different users. Therefore, rate control is also a method for implementing scheduling policies. Background technique [0002] With the vigorous development of mobile communications, various new services emerge in an endless stream, among which the development of data services is particularly rapid. However, the limitations of wireless spectrum resources and propagation environment affect the improvement of data service transmission rate to a certain extent. Therefore,...
