Abstract: Disclosed is a method for determining open loop power control parameters. A first set of key performance indicators associated with a first set of open loop power control parameters is obtained from one or more first base stations. A statistical model is determined based at least partly on the first set of key performance indicators and the first set of open loop power control parameters. A second set of open loop power control parameters is determined based at least partly on the statistical model.

Abstract: A solution for allocating N radio beam configurations to access nodes including, in some embodiments, a method comprising storing a beam library defining a set of radio beam configurations for a coverage area. A coverage area is divided into sub-areas, and a set of channel quality metrics is collected, as is a traffic density parameter for each sub-area. The following steps are performed: selecting N radio beam configurations from the set of radio beam configurations; mapping each sub-area with one of the selected N radio beam configurations; computing a service performance for the selected N radio beam configurations; the service performance is weighted by the traffic density parameters. The service performance are stored as linked to each radio beam configuration of the selected N radio beam configurations. Based on the stored service performances, a set of N radio beam configurations is selected and the N radio beam configurations are allocated.

Abstract: To provide fairness between served apparatuses while keeping radio frequency exposure below a defined limit, an apparatus collects, per a sampling period, historical data on tokens at the sampling period, the historical data including at least number of tokens requested during the sampling period, wherein a token is indicative of an amount of radiated power for transmission of a data element. The collected historical data is transmitted to a wireless network. The wireless network determines hindsight based estimations for maximum token consumptions that should have been allowed, and then determines for a control policy, using at least numbers of tokens requested in the historical data received and corresponding hindsight based estimations determined, updated weight values, and transmit them to the apparatus. The apparatus then updates its control policy correspondingly, applies it, collects historical data, and transmits it to the wireless network to obtain updated weight values.

Abstract: A method includes determining, for a Bayesian model, a search region for determining a pair of thresholds having a minimum threshold and a maximum threshold, wherein the minimum threshold value deactivating at least one cell of a group of cells and the maximum value activating at least one cell of the group, defining the search region to have a starting point in which the pair of thresholds has values corresponding to the cells included in the group being activated during a deployment period and the values increase in the search region, retrieving a key performance indicator, associated with the group of cells, collected during latest deployment period, retrieving a value of the minimum threshold and a value of the maximum threshold applied during the latest deployment period and converting the retrieved values, and updating based on the key performance indicator and the retrieved and converted values.

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.
