Control Signaling Structure

There is disclosed a method of operating a transmitting node in a millimeter-wave communication network. The method includes transmitting millimeter-wave signaling in a transmission timing structure, the transmission timing structure including N time interval elements sequentially ordered in time, the millimeter-wave signaling including N separate signaling structures, each signaling structure being transmitted in a different one of the time interval elements. N is an integer multiple of 2. A first subset of the N separate signaling structures corresponds to control signaling, the subset including 2{circumflex over ( )}m signaling structures consecutive in time beginning with the signaling structure of the first time interval element, and m is an integer such that 2{circumflex over ( )}m<=N. A second subset of the N separate signaling structures corresponds to data signaling, the second subset comprising 0 or an integer number of signaling structures. The disclosure also pertains to related devices and methods.
