  • Publication number: 20200396753
    Abstract: Uplink radio transmissions (22) from a radio device (10) are scheduled by allocating radio resources for the uplink radio transmissions (22) and controlling a transmit power of the uplink radio transmissions (22). Depending on a bandwidth of radio resources to be allocated for an uplink radio transmission (22) and a current value of the transmit power, an estimate of the signal-to-noise ratio of the uplink radio transmission (22) is determined. The estimate of the signal-to-noise ratio is compared to at least one of the lower target and the upper target. Depending on a result of the comparison, the bandwidth is adapted, and radio resources for the uplink radio transmission (22) are allocated in accordance with the adapted bandwidth.
