METHOD AND APPARATUS FOR CENTRALIZED SCHEDULING WITH INTER-CELL INTERFERENCE COORDINATION IN HETEROGENEOUS NETWORKS

摘要

PURPOSE: a kind of method and device thereof of centralized scheduling provide the small base station between isomerization unit by minimizing interference covering expansion technique in heterogeneous network with maximize handling capacity. ;CONSTITUTION: communication unit is connected to one or more base stations. Control unit collects channel information in terminal and base station and communication unit (406). Control unit determines interference base station in the terminal using the channel information (416) of acquisition. Control unit control base station selection scheduling terminal utilizes interference base station information (418). Control unit control interference base station to stops the terminal scheduling point (414) of data transmitting. ;The 2013 of copyright KIPO submissions;[Reference numerals] (402) setting biasing is to extend a series of small base station; (404) macro base station of blank pattern is set; (406) total canal,Trunk canal information is from all base stations; (408) selection serving cell is sure to terminal; (410) outage condition cannot be satisfied between the terminals in the small base station of spreading range to macro base station by borrowing one terminal of object handover; (412) subframe carries out the macro base station of blanking; (414) stop data transmission in all macro base stations in the middle; (416) determine that cell is interference relative to each terminal; (418) scheduling of selection candidate terminal is in current subframe; Control (420) unit between interference relative to selection scheduling candidate terminal; (AA) start
