Abstract:
1. A method of allocating radio resources, in a base station, to the base station and a mobile station, comprising: obtaining a ratio between traffic of an uplink and traffic of a downlink; allocating the radio resources to the uplink and the downlink for the mobile station; and dividing time into a plurality of time periods corresponding to at least one of days of a week and hours of a day, and allocating empirical data regarding the traffic of the uplink and the traffic of the downlink to the respective time periods, wherein said obtaining the ratio includes; obtaining a current ratio between the traffic of the uplink and the traffic of the downlink based on current traffic; and obtaining a weighted average of the empirical data corresponding to a present time period and the current ratio by weighting the empirical data and the current ratio with respective weighting factors that are determined on a base-station specific basis depending on volatility of traffic, wherein said allocating the radio resources allocates the radio resources to the uplink and the downlink according to the weighted average.
