Synchronisation signaling for wireless communication network

A transmitting radio node for a wireless communication network, the transmitting radio node comprising:

• processing circuitry;
• and
• radio circuitry connected to the processing circuitry, to configure the transmitting radio node to:
• transmit first synchronisation signaling comprising one or more first pairs of allocation units carrying broadcast signaling;
• and
• transmit second synchronisation signaling comprising one or more second pairs of allocation units carrying broadcast signaling,
• the broadcast signaling carried in first and second pairs of allocation units being cross-wise associated, and the cross-wise association of the broadcast signaling being at an allocation unit level,
• the cross-wise association of the broadcast signaling carried on a leading allocation unit of a first pair of allocation units associated to a trailing allocation unit of a second pair of allocation units, and
• the trailing allocation of the first pair being a negative complex conjugate of the leading allocation unit of the second pair.

A method of operating a receiving radio node in a wireless communication network, the method comprising:

• communicating based on received first synchronisation signaling comprising one or more first pairs of allocation units carrying broadcast signaling, and received second synchronisation signaling comprising one or more second pairs of allocation units carrying broadcast signaling,
• the broadcast signaling carried in first and second pairs of allocation units being cross-wise associated, and the cross-wise association of the broadcast signaling being at an allocation unit level,
• the cross-wise association of the broadcast signaling carried on a leading allocation unit of a first pair of allocation units associated to a trailing allocation unit of a second pair of allocation units, and
• the trailing allocation of the first pair of allocation units being a negative complex conjugate of the leading allocation unit of the second pair.
