Patent ID: 7076250

Claim:
A method for planning and/or evaluation of a downlink coverage in a radio network comprising one or more service areas, each service area comprising at least one base station defining at least one cell, the method comprising the steps of: defining a grid on the one or more service areas; assigning the at least one cell to pixels defined by the grid; assigning a pilot power to the at least one cell; estimating a desired downlink transmission power for the at least one cell; and comparing the desired downlink transmission power to a maximum transmission power of the one or more base station; wherein the desired downlink transmission power P BS is estimated using the formula P BS =P traffic +P pilot , where P pilot is the pilot power and P traffic = ( E b N 0 ) req G traffic â¢ âˆ‘ p = 1 âˆ â¢ N p â¡ [ L p â¡ ( N th + I other , p ) + Ï‰ p â¢ P pilot ] 1 - ( E b N 0 ) req G traffic â¢ âˆ‘ p = 1 âˆ â¢ N p â¢ Ï‰ p is a power for one or more downlink traffic channels.
