Synchronisation signaling for wireless communication network

A transmitting radio node for a wireless communication network, the transmitting radio node comprising processing circuitry, the processing circuitry being configured to:

• cause transmission of synchronisation signaling in a synchronisation time interval, the synchronisation signaling comprising primary synchronisation signaling, the primary synchronisation signaling spanning two or more adjacent symbol time intervals of allocation units of the synchronisation time interval, a signaling sequence associated to one of the allocation units being composed of a plurality of composite sequences that are based on a same root sequence.

A method of operating a receiving radio node for a wireless communication network, the method comprising communicating with one or both of the wireless communication network and a transmitting radio node based on received synchronisation signaling, the synchronisation signaling spanning a synchronisation time interval, and the synchronisation signaling comprising primary synchronisation signaling, the primary synchronisation signaling spanning two or more adjacent symbol time intervals of allocation units of the synchronisation time interval, a signaling sequence associated to one of the allocation units being composed of a plurality of composite sequences that are based on a same root sequence.
