Abstract: At a node for local data transmission which is under an overlay wide area macro network operated on the same frequency layer, conditions of a wide area cell of the overlay wide area macro network are obtained, wherein the wide area cell is measured as a cell with a certain received signal level at a location of the node. Based on the conditions of the wide area cell, an allocation of channels for local area data transmission from the node is set such that interference of the channels for the local area data transmission with allocated wide area channels of the wide area cell is avoided or minimized.
