A method (20, 40) of planning deployment of a new network node in a communications network, the method is performed by a system comprising an entity and an unmanned aerial vehicle, UAV,, the method (20, 40) comprising the UAV performing the following steps: - flying to each candidate location (c1,..., c9) of a set of candidate locations where a new network node might be deployed, for finding the best location for deployment of the new network node, - performing, at each candidate location (c1,..., c9), measurements on a first link L a between the UAV and at least a first existing network node of the communications network, and measurements on a second link L b between the UAV and at least a second existing network node of the communications network, the UAV being configured to associate the measurement results to the candidate location at which they were taken, and - providing measurement results of the measurements to the entity, and the method (20, 40) further comprising the entity performing the following steps: - receiving, from the UAV, the measurement results comprising the first measurements corresponding to the first link L a and the second measurements corresponding to the second link L b, and - determining, based at least on the received measurement results, a deployment location for the node, for a total link between the first and second existing network nodes (2a, 2b), the total link being the link between the first existing network node and a node placed at the best location found by the UAV and the link (L b) between the node placed at the best location found by the UAV and the second existing network node, the determining comprising determining a best location out of the candidate locations, wherein the best location is based on the measurement by finding the location where both link L a and L b are strong in terms of link quality. - flying to each candidate location (c1,..., c9) of a set of candidate locations where a new network node might be deployed, for finding the best location for deployment of the new network node, - performing, at each candidate location (c1,..., c9), measurements on a first link L a between the UAV and at least a first existing network node of the communications network, and measurements on a second link L b between the UAV and at least a second existing network node of the communications network, the UAV being configured to associate the measurement results to the candidate location at which they were taken, and - providing measurement results of the measurements to the entity, and the method (20, 40) further comprising the entity performing the following steps: - receiving, from the UAV, the measurement results comprising the first measurements corresponding to the first link L a and the second measurements corresponding to the second link L b, and - determining, based at least on the received measurement results, a deployment location for the node, for a total link between the first and second existing network nodes (2a, 2b), the total link being the link between the first existing network node and a node placed at the best location found by the UAV and the link (L b) between the node placed at the best location found by the UAV and the second existing network node, the determining comprising determining a best location out of the candidate locations, wherein the best location is based on the measurement by finding the location where both link L a and L b are strong in terms of link quality. - receiving, from the UAV, the measurement results comprising the first measurements corresponding to the first link L a and the second measurements corresponding to the second link L b, and - determining, based at least on the received measurement results, a deployment location for the node, for a total link between the first and second existing network nodes (2a, 2b), the total link being the link between the first existing network node and a node placed at the best location found by the UAV and the link (L b) between the node placed at the best location found by the UAV and the second existing network node, the determining comprising determining a best location out of the candidate locations, wherein the best location is based on the measurement by finding the location where both link L a and L b are strong in terms of link quality.
