SMALL CELL DISCOVERY

摘要

There is provided a method, comprising: detecting, by a network node (200) of a local area cell (106), whether or not there is at least one user terminal (104) connected to a macro cell (100) present in a coverage area of the local area cell (106); upon detecting the presence of the at least one user terminal (104), causing a transmission of a request message to an associated cell (100 or 210), wherein the request message comprises a resource allocation request for a discovery signal transmission (206) on an operating frequency (F2) of the macro cell (100); causing a reception of a response message from the associated cell (100 or 210), wherein the response message comprises an indication of allocated resources for the discovery signal transmission (206); and causing a transmission of the discovery signal (206) on the indicated resources in order to allow the at least one user terminal (104) in the cover-age area of the local area cell (106) to detect the discovery signal transmission (206).
