  • Patent number: 10966207
    Abstract: Radio circuitry controls wireless transmit power to User Equipment (UEs). The radio circuitry receives wireless signals generated using different Quadrature Amplitude Modulation (QAM) constellation sizes. The circuitry converts the wireless signals into data symbols and converts the data symbols into uplink data. The radio circuitry determines when average symbol error is excessive for a set of QAM constellation sizes. The radio circuitry determines when the UEs are concentrated in an inner coverage range. When both the average symbol error is excessive and the UEs are concentrated in the inner range, the radio circuitry reduces transmit power and transmits wireless signals to the UEs at the reduced transmit power. When the average symbol error is no longer excessive or when the UEs are no longer concentrated in the inner range, the radio circuitry increases transmit power and transmits wireless signals to the UEs at the increased power level.
