12. A wireless communication device, comprising:
a radio interface for connecting to a wireless communication network; and
at least one processor,
the at least one processor being configured to:
identify a set of multiple different subcarrier spacings which are supported for transmission of synchronization signals;
select a subset of one or more subcarrier spacings from the set of different subcarrier spacings;
based on the selected subset of one or more subcarrier spacings from the set of different subcarrier spacings supported for transmission of the synchronization signals, receive synchronization signals from the wireless communication network;
based on the synchronization signals, the wireless communication device perform synchronization to a base station of the wireless communication network; and
wherein the wireless communication device is configured to select the subset of the one or more subcarrier spacings by identifying a set of one or more frequency ranges in which the signals from the wireless communication network are received and based on a mapping of the one or more subcarrier spacings to frequency ranges,
wherein the wireless communication device is configured to select the subset of subcarrier spacings based on information received during preparation of a handover from a first base station to a second base station of the wireless communication network, and
wherein for each of the received synchronization signals a length of a cyclic prefix of modulation symbols is based on the utilized subcarrier spacing.
