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.

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: Inter-radio access technology (inter-RAT) load balancing under multi-carrier dynamic spectrum sharing (SS) context is provided. One method may include splitting shared radio-frequency resources into orthogonal resource pool shares. The method may include receiving a load metric for each of a plurality of radio access technologies. The method may include assigning, based on the load metric, one of the resource pool shares to each of the plurality of radio access technologies. In addition, the method may include dynamically adjusting a proportion of the assigned resource pool shares based on the load metric of each of the plurality of radio access technologies at corresponding carriers. The method may include assigning a primary carrier to a user equipment based on the load metric, the resource pool share, a coverage of the carriers' physical channels, and a type of multi-carrier operation for each of the plurality of radio access technologies.

Abstract: Systems, methods, apparatuses, and computer program products for determining a grid-of-beams (GoB) are provided. One method may include collecting network data for training a neural network, train the neural network, using the collected data, to learn a non-discounted cumulative reward Q that evaluates a benefit of including a given beam into a grid-of-beams (GoB), iteratively applying the trained neural network to select at least one optimal beam to include in the grid-of-beams (GoB), and selecting one or more beams from the grid-of-beams (GoB) to transmit to a user equipment or to receive transmission from the user equipment.

Abstract: A method may include receiving, at a reinforcement learning load balancer, a load metric related to available resources of a carrier. The method may also include calculating, based on the load metric, an update to carrier assignment parameters for a user. The method may further include calculating, based on the load metric, an update to uplink/downlink split proportions and resource pool split proportions. In addition, the method may include predicting an impact of the update to the carrier assignment parameters, the update to the uplink/downlink split proportions, and the update to the resource pool split proportions to the load metric. Further, the method may include communicating the update to carrier assignment parameters, the update to uplink/downlink split proportions, and the update to resource pool split proportions to one or more radio resource managers of corresponding one or more radio access technologies for application to a communication network.
