Abstract: There is disclosed a method of operating a radio node in a wireless communication network. The method includes communicating based on a signaling structure, the signaling structure pertaining to a time domain interval and comprising a plurality of symbol time intervals, wherein to each symbol time interval, there is associated one cyclic prefix interval of a cyclic prefix interval type of a set of at least two types, wherein a first type pertains to a cyclic prefix interval corresponding to a first number N of processing samples, and a second type pertains to a cyclic prefix interval corresponding to a second number M of processing samples, wherein M is larger than N, and wherein both N and M are multiples of a base factor B. The disclosure also pertains to related devices and methods.

Abstract: A method and apparatus for compensating for nonlinearities in a non-linear device for manipulating a signal is described. Shortly before an initial discrete power increase is applied to the device, a first pre-distortion function is generated on the basis of a first set of DPD parameters and applied to the signal before it reaches the device. A predetermined time period after the initial power increase, the first pre-distortion function stops being applied to the signal, and a second pre-distortion function is generated on the basis of a second set of DPD parameters and applied to the signal. Shortly before a subsequent discrete power increase is applied to the device, the first pre-distortion function is generated on the basis of the first set of DPD parameters and applied to the signal.
