METHOD AND APPARATUS FOR DYNAMICALLY ALLOCATING RESOURCE

摘要

A dynamic resource allocating apparatus of a first base station that manages a first cell in a cellular communication system including the first cell and a plurality of cells adjacent to the first cell determines time resource division vector in which one time resource division period is formed of a plurality of time division intervals and calculates time resource division vector for maximizing utilities of user terminals in a set up objective function to update the time resource division vector. Among the plurality of time division intervals, a first time division interval is operated by a time resource reuse coefficient 1 for user terminals positioned in center regions of a first cell and a plurality of adjacent cells, and the remaining time division intervals excluding the first time division interval are operated by a time resource reuse coefficient n for user terminals positioned at edges of the first cell and the plurality of adjacent cells.

1. A method of allocating a time resource by a resource allocating apparatus of a cellular communication system including a plurality of cells, the method comprising:
dividing a time resource of one period into a first time division interval and a second time division interval and dividing the second time division interval into a plurality of third division intervals; and setting up a first level of transmission power in cells to which corresponding third division intervals are allocated to be no less than a second level of transmission power in other cells in the third division intervals, wherein magnitudes of the first time division interval and the plurality of third division intervals are changed in accordance with distribution of user terminals of the plurality of cells and load levels of the plurality of cells.
