Abstract: A wireless communication device identifies a set of multiple different subcarrier spacings which are supported for transmission of synchronization signals. From the set of different subcarrier spacings, the wireless communication device selects a subset of one or more subcarrier spacings. Further, the wireless communication device receives signals from the wireless communication network. On the basis of the subcarrier spacings of the subset, the wireless communication device monitors the received signals for synchronization signals.

Abstract: The present invention relates to a method for determining a position of a terminal device (110) in a wireless communication system (100). According to the method, a first message (130-133) is broadcasted by the terminal device (110). The first message (130-133) comprises a positioning request and a terminal identifier identifying the terminal device (110).
