Elevation restriction beamforming in wireless systems
Methods, systems, and devices for beamforming in environments with angular constraints are described. A wireless device such as a user equipment (UE) or base station may configure beam parameters based on a sensitivity level of a neighboring wireless device (e.g., a satellite). The configuration of beam parameters may be based on an interference power profile (e.g., threshold(s) indicated by an interference power profile). The interference power profile may specify a mask, which may indicate allowed or unintended directions for transmission or a transmission power mask. A beamformed transmission may be in accordance with the configured beam parameters, which may result in a reduced transmission power in one or more directions, compliance with total power limits, peak power limits, or energy radiated over a period of time, or any combination thereof.
