A method for improving the radio cell illumination in a cellular mobile radio system provides that there are a number of neighboring cells adjoining each other and partially overlapping each other, wherein in the marginal region of each cell is arranged at least one fixed transmitter. In order to obtain optimized radio cell illumination, it is provided that the fixed transmitters of neighboring cells directly adjoining a cell transmit to this cell with the same channel group as the fixed transmitter of the cell to be supplied itself. In this way a mobile station located in the cell is supplied not only by one fixed transmitter, but also by the fixed transmitters of neighboring cells. Each fixed station is assigned several sector aerials which at least partially overlap in their transmitting range defined by sectors and which together sweep across at least a range of 360.degree..

[ We claim:] [1.] A method as of radio cell illumination, comprising the steps of:forming a cluster of neighboring and adjoining cells, each cell having a marginal region;arranging at least one fixed transmitter in the marginal region of each cell, including a first fixed transmitter arranged at the marginal region of a first cell and having a sector aerial which sweeps across at least the region of the first cell with radio frequencies of a first channel group;arranging the fixed transmitters of at least two neighboring cells directly adjoining the first cell to transmit to the first cell with the same radio frequencies as the first fixed transmitter;each of the fixed transmitters having a fixed channel allocation;supplying a mobile station situated in the first cell simultaneously with signals in the same channel group of radio frequencies from the first fixed transmitter of said cell and the fixed transmitters of not more than two adjacent cells; andtransmitting from each of said three different fixed transmitters a signal with an individual variable power, and adjusting the power of said three fixed transmitters proportional to the contribution of the respective fixed transmitter received at a receiver input of the mobile station.
