Adaptive channel allocation method and apparatus with a power control in a mobile communication system

摘要

(57) Abstract In the cellular communication system, measuring down link interference the base station while the dying and the cell and the channel which is used for the connection between the mobile stations method and the device in order to allot are offered. Through all system, inside each cell, just the quantity of the size which is equal to the size of change of route profit with the mobile station and base station inside that cell substantially, furthermore in order, with the mark which is opposite to the mark of the change quantity of route profit, for harmony of power level of uplink and power level of down link to change, level of both is adjusted. In this electrical adjustment plan, you have considered that system wide of interference of uplink and down link there is strong correlation during measurement. Consequently, making use of suitable electrical adjustment plan, each cell uplink carrier anti- interference of the active free channel (C/I) decides ratio inside that cell, selects the approved free channel which has the C/I value which is inside the specified scope of supply. When being larger than uplink C/I value of the channel where uplink C/I of the approved free channel presently is allotted to connection, in order that connection re-to be allotted in the approved free channel, the transferring/changing inside the cell is executed. As for this technology, although adaptation channel allotment plan is offered to system such as the analog cellular communication system which cannot do down link interference measurement it is beneficial.
