Abstract
The invention relates to a method and a device for supporting traffic loads to a very high extent for a cell (2) of a radio base station (1) in a cellular radio communication network in communication with mobile stations (MSA, MSB, MSC) within the range of the radio base station. Frequency hopping and adaptive antenna is used to provide at least two cell regions. A hopping list (HSN) of frequencies for the cell is allocated, and the frequency offset numbers (MAIOs) in the hopping list, to set the allowable frequency hopping procedure of the cell. The position in the cell for each mobile station within the cell boundary is determined. A frequency offset number (MAIO) is allocated for each mobile station. The cell is provided with at least one different lobe (L1′,L2′;L1″, L2″, L3″) for each cell region using at least one different adaptive antenna lobe for each cell region. The lobes in the cell have suppression between each other. A different set of the frequency offset numbers (MAIOs) is assigned for each region. Each set for each of the cell regions has a value increment by at least two, and so that different regions have different sets of the frequen…
