REFERENCE SIGNALING FOR WIRELESS COMMUNICATION

Abstract

There is disclosed a method of operating a transmitting radio node in a wireless communication network, the method including transmitting reference signaling based on a reference pilot sequence, the reference pilot sequence being one of a set of reference pilot sequences, at least one reference pilot sequence of the set being a subsequence of another reference pilot sequence of the set. The disclosure also pertains to related devices and methods.

Description
