  • Channel-matrix dependent step size for iterative precoding matrix calculation
    Patent number: 11962372
    Abstract: A channel matrix representing characteristics of a multi-path channel between a transmitter device (210) equipped with multiple transmitter antennas (211, 212, 213, 214, 215) and at least one receiver device (220, 230, 240) equipped with one or more receiver antennas (221, 222, 231, 232, 241, 242). The channel matrix is organized in one or more channel vectors each associated with a corresponding one of the one or more receiver antennas (221, 222, 231, 232, 241, 242). An iterative optimization algorithm is applied to determine a precoding matrix from the channel matrix. At least one step size of the iterative optimization algorithm is set depending on a vector norm of at least one of the channel vectors. Multi-antenna transmission by the transmitter device (210) is then controlled based on the determined precoding matrix.

  • Uplink scheduling based on upper and lower SNR targets
    Patent number: 11647497
    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.
