A first transmission power associated with a primary carrier and a second transmission power associated with a secondary carrier are determined. Location data and channel state information from a user device utilizing the primary carrier and the secondary carrier are received. An interference level may be determined using the channel state information. Based on the location data and the interference level, the second transmission power associated with the secondary carrier is reduced and the first transmission power of the primary carrier is increased. In some aspects, a beamforming technique is applied for downlink transmissions via a 5G New Radio unlicensed band. In some aspects, upon detection of an increase of 3 dBi antenna gain, the second transmission power is reduced by 1 dBm. ## Claims ### Claim 1 A system for optimizing coverage and power usage in a network deploying an unlicensed band, the system comprising: an antenna array comprising one or more antenna elements;
