Abstract: A method is proposed for operating a re-configurable reflective device, RRD, the RRD being re-configurable to provide multiple spatial filters, each one of the multiple spatial filters being associated with a respective input spatial direction from which incident signals on a data radio channel are accepted and with a respective output spatial direction into which the incident signals are reflected by the RRD. The method comprises: receiving, by the RRD from a first communication node, CN1, on a positioning radio channel different from the data radio channel, a CN1 reference signal, determining, by the RRD, an estimated CN1 angle of arrival of the CN1 reference signal, and reconfiguring the RRD based on the estimated CN1 angle of arrival.

Abstract: A method is disclosed performed by a transmitter node, for enabling reception beam selection at one or more receiver nodes. The method comprises obtaining a polarization profile, wherein the polarization profile defines a respective polarization for a sequence of probing occasions. The method comprises transmitting a pilot signal in each probing occasion of the sequence of probing occasions according to the polarization profile, in one single transmission beam. The polarization profile defines a first polarization to be used in N probing occasions and a second polarization to be used in M probing occasions in the sequence of probing occasions, where M is smaller than N and M is non-zero.

Abstract: An antenna assembly (10) includes a substrate (24) and an array of antenna elements (26). Each antenna element is supported by the substrate at respective locations so that the antenna elements are arranged in space in a helix pattern (28). The helix pattern has a pitch along an axis about which the helix pattern turns. An arc length spacing of the antenna elements along the helix pattern and the pitch are arranged so that, in a transmit mode, a radio frequency (RF) signal fed to each of the antenna elements results in emission of a radiated signal with a rotational wave front from the antenna assembly at a first frequency and a first mode.

Abstract: A method includes receiving (402) a plurality of reference signals (301-303) at an antenna port of a communication device (101). Each reference signal (301-303) is sent using a corresponding precoder. The precoder is selected from a first set of precoders. The method further includes determining (403) a channel estimate based on the received plurality of reference signals (301-303), and selecting (404) a precoder from a second set of precoders based on the determined channel estimate. The second set of precoders comprises at least one precoder in addition to the precoders of the first set of precoders. The method includes sending (405) an indication (304) relating to the selected precoder.
