Abstract: Beam and antenna array split configuration optimization is disclosed. A network node device generates a beam dictionary defining a set of beams. The network node device estimates a traffic density distribution for a radio channel based on obtained channel quality information. The network node device determines, for each of at least two array split configurations associated with a transceiver antenna array of the network node device, a set of optimal beams from the beam dictionary that optimizes a utility function, based on the estimated traffic density distribution. The network node device selects an array split configuration that maximizes the utility function across a coverage area of a radio cell associated with the network node device. The network node device applies the selected array split configuration to the transceiver antenna array in response to evaluating that the selected array split configuration improves downlink performance.

Abstract: Various example embodiments may relate to link adaptation. An apparatus may determine a first signal quality estimate for a signal. The apparatus may further determine a BLER estimate based on acknowledgements or decoding results for data blocks of the signal. The apparatus may further determine a second signal quality estimate for the signal based on the BLER estimate. The apparatus may further determine a signal quality offset based on a difference between the first signal quality estimate and the second signal quality estimate. The apparatus may further determine transmission parameter(s) for at least one subsequent data block based on the first signal quality estimate and the signal quality offset.

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.
