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.

Abstract: An improved NR-U framework allows a gNB to repeat RLM-RS with the same index over each sub-band of an unlicensed spectrum. For example, a RLM-RS with the same indices are repeated by the gNB over the sub-bands of a wideband channel in an unlicensed spectrum. By monitoring the different sub-bands, a UE may find one or more sub-bands in which the RLM-RS having a particular index is successfully transmitted at a subsequent time.

Abstract: A technique comprising: receiving a set of digital signals representative of a set of analogue electrical signals generated by radio transmissions in one or more antenna elements; generating at least two beamformed signals from the same set of digital signals; multiplying together said beamformed signals; and performing demodulation at least partially on an output of multiplying said beamformed signals.
