When the outage condition is satisfied, the base station transmits the optimized beamformer weight matrix to each remote radio head, which transmits downlink signals using a kth beamformer vector of the optimized beamformer weight matrix.

  • Patent number: 11259256
    Abstract: A wireless device receives configuration parameters indicating a first PDSCH processing capability value associated with a first power state of a cell, and a second PDSCH processing capability value associated with a second power state of the cell. The first PDSCH processing capability value indicates a first applicable gap between receiving a TB and transmitting an acknowledgement when the cell is in the first power state. The second PDSCH processing capability value indicates a second applicable gap between receiving a TB and transmitting an acknowledgement when the cell is in the second power state. A first TB is processed based on the first PDSCH processing capability value, when the cell in the first power state. A command is received indicating transitioning to the second power state. A second TB is processed based on the second PDSCH processing capability value, in response to transitioning to the second power state.

  • Patent number: 11224022
    Abstract: A method performed by a radio network node for deciding an Automatic Gain Control (AGC) mode to be used for a received signal in a wireless communications network is provided. The radio network node estimates (301) a type of interference scenario affecting the received signal and obtains (302) information about channel quality of channels between the radio network node and connected wireless devices. Based on the estimated type of interference scenario and the obtained information about the channel quality, the radio network node dynamically decides (303) for the received signal, which AGC mode out of the following ACG modes to be used: —a slow AGC using a release timer for releasing an AGC state, —a fast AGC using a release timer for releasing an AGC state, and—a fast AGC using a trigger timer triggering an AGC state a first time interval before an interference period, and the release timer releasing the AGC state a second time interval after said interference period ends.

The method is for mitigation of an interfering signal leaked into a frequency range of a desired signal due to non-linearity of hardware components of the receiver. The method comprises receiving a composite signal comprising the desired signal and the interfering signal, filtering the composite signal using a spatial filter for a channel response of the desired signal to provide a first intermediate signal component, and filtering the composite signal using a spatial filter for a channel response of the interfering signal to provide a second intermediate signal component. The method also comprises estimating a squared amplitude of the interfering signal based on the second intermediate signal component and a model of the non-linearity, and estimating the desired signal based on the first intermediate signal component, the estimated squared amplitude of the interfering signal, and the model of the non-linearity.
