    • 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).
    • 提供了一种方法,包括:由局域单元(106)的网络节点(200)检测是否存在连接到存在于所述局域单元(106)中的宏小区(100)的至少一个用户终端(104) 局部区域单元(106)的覆盖区域; 在检测到所述至少一个用户终端(104)的存在时,引起对相关联的小区(100或210)的请求消息的传输,其中所述请求消息包括用于发现信号传输(206)的资源分配请求 宏小区(100)的工作频率(F2); 导致来自所述相关联的小区(100或210)的响应消息的接收,其中所述响应消息包括用于所述发现信号传输的分配的资源的指示(206); 并且在所指示的资源上引起发现信号(206)的传输,以便允许本地区域小区(106)的覆盖年龄区域中的至少一个用户终端(104)检测到发现信号传输(206 )。
