Abstract: A method includes selecting a received signal strength threshold level for determining whether an uplink resource of a terminal device is allocated from a first frequency band or from a second frequency band, and wherein the first frequency band is for terminal devices having a received signal strength above the received signal strength threshold level and the second frequency band is for terminal devices having the received signal strength below the received signal strength threshold level; outputting the received signal strength threshold level to be broadcasted in a cell; acquiring received signal strength values measured for a plurality of terminal devices in the cell and further acquiring and at least one performance metric target; and changing the received signal strength threshold level on the basis of the measured received signal strength values and the at least one performance metric target.

Abstract: Systems, methods, apparatuses, and computer program products for multi-user (MU) multiple-input multiple-output (MIMO) user pairing selection are provided. One method may include selecting multi-user multiple input multiple output (MU MIMO) candidate beams using deep neural network(s) (DNNs), and selecting paired users based on the selected beams. The deep neural network(s) (DNNs) are trained to maximize multi-user priority metric (MU-PM) or a heuristic of the multi-user priority metric (MU-PM).

Abstract: A method and apparatus may include adapting transmission opportunities of the first network node. A radio-technology of the apparatus coexists with at least one other radio-access technology of a network node. The adapting may include adapting when the apparatus is able to perform transmissions. The method may also include transmitting in accordance with a transmitting period. The transmitting period corresponds to a time over which the apparatus is configured to perform transmitting and to be muted. The transmitting may include transmitting on an unlicensed carrier.
