Signaling structure for wireless communication network
There is disclosed a method of operating a radio node in a wireless communication network, the method including communicating based on a signaling structure, the signaling structure including a number R of long symbols and/or a number Nsym of regular symbols, wherein R and/or Nsym is based on the subcarrier spacing associated to the signaling structure and/or a cyclic prefix length of a long symbol and/or a cyclic prefix length of a regular symbol. The disclosure also pertains to related devices and methods.
