Embodiment Construction

[0026] According to the frame structure analysis of the TD_SCDMA standard and the characteristics of 3G and future services, the present invention proposes a method for realizing slow dynamic channel allocation (DCA) when wireless resource allocation is performed, and the adjacent cells formed during allocation A solution to the cross-slot interference is proposed. like figure 1 Shown, method of the present invention comprises the following steps:

[0027] Step 110, start, determine dynamically allocated time slot resources and fixedly allocated time slot resources in the system frame structure;

[0028] Step 121, for each cell, set a dynamic channel allocation timer, and assign a value to the timer, and schedule a time period;

[0029] Step 122, making statistics on the uplink and downlink bandwidth requirements of the cell;

[0030] Step 123, judging whether the timer is overtime, if yes, execute step 130, otherwise return to step 122;

[0031] Step 130, calculating a co...

Abstract

The method includes steps: determining assignable dynamic time slot resources and fixed time slot resources in frame structure of communication system; carrying out statistics for demanding of up going and down going bandwidths on small zone or cluster of small zone in a period of time preset; based on result of statistics, calculating parameters of reflecting demand relation between up going and down going bandwidths; based on the said parameters, allotting assignable dynamic time slot resources for up going and down going bandwidths. The invention realizes dynamic channel allocation at slow speed in TD_SCDMA.

Description

technical field [0001] The invention relates to a method for realizing dynamic channel allocation in wireless resource management in a wireless communication system, in particular to a method for realizing slow dynamic channel allocation in a TD_SCDMA wireless communication system. Background technique [0002] TD_SCDMA (Time Division Synchronous Code Division Multiple Access) standard wireless communication system is a TDD (Time Division Duplex) system. In this system, the time slot resources in the wireless frame structure can be dynamically allocated to the uplink and downlink of time slots according to the service distribution of the cell. The feature that time slot resources can be allocated dynamically makes the TD_SCDMA standard wireless communication system have two characteristics: the first is that the resource allocation of this system is flexible, which can better adapt to various business needs and changes in requirements; the second is to realize the second On...
