Abstract
The present invention relates to a method and a communication network node for enabling automatic planning and handling of root sequences used at random access in a communication network system, wherein user equipments (18) are accessing a cell (19a) being served by said communication network node. Root sequence usage information from neighboring cells (19b, 19c) is acquired. Root sequence conflicts between root sequences used in said served cell (19a) and root sequences used in said neighboring cells (19b, 19c) are detected. When no conflict is detected, appropriate new root sequence(s) is/are selected. Otherwise, detected root sequence conflicts are resolved by deriving a new set of root sequences.
