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.
Claims25
A method of enabling synchronization in a wireless communication network, the method comprising:
- a wireless communication device identifying a set of multiple different subcarrier spacings which are supported for transmission of synchronization signals;
- the wireless communication device selecting a subset of one or more subcarrier spacings from the set of different subcarrier spacings;
- the wireless communication device receiving signals from the wireless communication network;
- and
- on the basis of the subcarrier spacings of the subset, the wireless communication device monitoring the received signals for synchronization signals.
A method of enabling synchronization in a wireless communication network, the method comprising:
- a base station of the wireless communication network identifying a set of multiple subcarrier spacings which are supported for transmission of synchronization signals;
- from the set of multiple different subcarrier spacings, the base station selecting a subset of one or more subcarrier spacings;
- and
- the base station transmitting synchronization signals on the basis of the subcarrier spacings of the subset.
