Abstract

A radio network sub-tiles reference signals (RSs) within a set of resource elements (REs) such that each sub-tiled RS occupies less than a time and/or frequency and/or power extent of its respective RE. The set of REs are dispersed across both frequency bins and time slots according to a pre-defined grid; and transmitted. The user equipment (UE) uses that pre-defined grid to locate within that transmission the set of dispersed REs. The UE accumulates and combines at least one subset of the sub-tiled RSs and estimates therefrom a quality; then reports uplink an indication of that estimated quality. Examples of the RSs include channel state information RSs, beam RSs and beam refinement RSs. Advantages are particularly relevant for 5G new radio systems.
