Abstract
A method of operating a distributed unit, DU, of a radio network node in a wireless communication system is provided. The method includes obtaining a value of an antenna subarray gain for a radio unit, RU, connected to the DU, estimating a transmission gain associated with a first downlink channel of the RU based on the antenna subarray gain, and calculating an effective isotropically radiated power, EIRP, level for the first downlink channel based on the estimated transmission gain of the first channel. The method further includes adaptively limiting EIRP of downlink signals transmitted by the RU on the first downlink channel based on the estimated transmission gain.
