Abstract
There is provided a solution for transmitting periodic signals in a cell. According to an aspect a method comprises in a network node: generating a plurality of radio beams in a cell, wherein said plurality of radio beams comprise a plurality of beam-forming configurations, and wherein at least one radio beam comprised in the plurality of radio beams comprises a discovery signal transmission; determining, for the at least one radio beam, whether or not at least one terminal device is located in a coverage area of the at least one radio beam; defining a transmission periodicity of the discovery signal transmission on the basis of said determining.
