Abstract: Systems, methods, apparatuses, and computer program products for dynamic target cell selection for application of RAN optimization are provided. One method includes receiving a request, from one or more radio access network optimization services, that comprises a list of attributes corresponding to characteristics of a cell and a cell selection criterion for each of the attributes, receiving, from one or more radio access network cells, a data stream comprising metrics for at least one of the cell or users in the cell. The method may also include generating, based on the received request and the metrics, a list of zero or more cells that meet the selection criterion for one of the radio access network optimization services or for a group of the radio access network optimization services, and sending, to a respective one of said one or more radio access network optimization services, the generated list of said zero or more cells that meets the selection criterion for the respective one or more radio access network optimization services.

Abstract: A method and apparatus for estimating and/or predicting mobility metric(s) for RAN optimization. One method includes receiving a request, from at least one RAN optimization service, to provide an estimate or prediction of a mobility metric for at least one UE or group of UEs or at least one cell. The request may include attributes describing characteristics of the mobility metric. The method may then include communicating with a RAN node to request data about the at least one UE or the group of UEs or the at least one cell associated with the request, receiving the requested data, and calculating the estimate or the prediction of the mobility metric using the requested data and based on the attributes received in the request from the at least one RAN optimization service.

Abstract: To maximize power saving in a radio access network comprising cells, an optimal action amongst actions comprising switching on one or more cells, switching off one or more cells, and doing nothing is determined using a trained model, which maximizes a long term reward on tradeoff between throughput and power, the trained model taking as input a load estimate. The trained model may be updated online using measurement results on load, throughput and power consumption.

Abstract: An apparatus, method and computer program is described comprising: executing, in a first mode of operation, a MIMO for one or more user devices eligible to transmit data in a slot of a packet scheduler, to generate MIMO operation outputs; obtaining, in a second mode of operation, estimated MIMO operation outputs for said one or more user devices from a lookup table; and determining whether to operate in the first mode of operation or the second mode operation.
