Method and Apparatus for Synchronization Signal Transmission

A method of operation at a network node in a wireless communication network, the method comprising:

• transmitting synchronization information in a plurality of beam directions within a defined time interval, according to a frequency division multiplexing scheme;
• wherein the frequency division multiplexing scheme comprises, for each transmission of synchronization information in a directional beam at a first transmission frequency, simultaneously performing one or more further transmissions of synchronization information in one or more further directional beams at respective further transmission frequencies.

A network node configured for operation in a wireless communication network, the network node comprising:

• communication circuitry configured to interface the network node to a directional antenna, or to interface the network node to a further network node configured for transmitting from the directional antenna;
• and
• processing circuitry configured to, via the communication circuitry, control the transmission of synchronization information from the directional antenna in a plurality of beam directions within a defined time interval, according to a frequency division multiplexing scheme, wherein the frequency division multiplexing scheme includes, for each transmission of synchronization information in a directional beam at a first transmission frequency, the simultaneous transmission of synchronization information in one or more further directional beams at respective further transmission frequencies.
