Abstract

Methods, systems, and devices for wireless communications are described. Generally, the techniques described herein may support generating an average effective isotropic radiated power (EIRP) mask in accordance with a set of weighted values to support interference management. For example, a wireless device may obtain one or more information bits for transmission by the wireless device via a transmit beam of multiple transmit beams of the wireless device and may generate, based on one or more directional parameters associated with a beamforming direction of the transmit beam, a set of weighted values for an average EIRP mask for the transmission of the one or more information bits. Additionally, the wireless device may transmit, via the transmit beam in the beamforming direction based on the one or more directional parameters and the set of weighted values, a signal comprising the one or more information bits to meet the average EIRP mask.
