Small Cell Discovery

摘要

There is provided a method, including detecting, by a network node of a local area cell whether or not there is at least one user terminal connected to a macro cell present in a coverage area of the local area cell; upon detecting the presence of the at least one user terminal, causing a transmission of a request message to an associated cell, wherein the request message includes a resource allocation request for a discovery signal transmission on an operating frequency of the macro cell causing a reception of a response message from the associated cell, wherein the response message includes an indication of allocated resources for the discovery signal transmission; and causing a transmission of the discovery signal on the indicated resources in order to allow the at least one user terminal in the cover-age area of the local area cell to detect the discovery signal transmission.
