Abstract
The present invention relates to a method and a communication network node for enabling automatic optimization of a random access preamble format usage in a communication network system. The network comprises the communication network node serving at least one cell to which user equipments are accessing. A random access preamble format is set for each cell and comprises a random access sequence length, T, and a random access preamble cyclic prefix length, T. First, the random access sequence length, Tis selected and then the random access preamble cyclic prefix length, T CP is selected. Based on the selected random access sequence length, T SEQ and random access preamble cyclic prefix length, T, which random access preamble format to use in said cell is selected.
