摘要： A communication device providing CSI feedback in a wireless communication system includes a transceiver to receive downlink reference signals and downlink signals including a reference signal configuration. A processor estimates an explicit CSI in the frequency domain. The processor selects a Doppler-delay-beam precoder matrix for a composite Doppler-delay-beam three-stage precoder, which is based on one or more codebooks including



one or more transmit-side spatial beam components,
one or more delay components, and
one or more Doppler-frequency components,




The processor calculates a CQI and/or a PMI and/or a rank indicator, RI, using the explicit CSI and the composite Doppler-delay-beam three-stage precoder, and reports the CSI feedback including the CQI, and/or the PMI and/or the RI. The one or more delay and/or Doppler-frequency components are defined by one or more sub-matrices of a DFT matrix or an oversampled DFT matrix.

摘要： An arrangement for an antenna for generating or receiving terahertz radiation can comprise a photoactive layer which can be activated by optical radiation in the range 1200 nm to 1700 nm, a substrate that is transparent to optical radiation and to which the photoactive layer is attached, and a first adhesion-promoting layer. The first adhesion-promoting layer is arranged between the photoactive layer and the substrate and connects them to each other, wherein first adhesion-promoting layer has a layer thickness of no more than 5 μm. The arrangement can also include and a carrier transparent to the optical radiation. The substrate is attached to the carrier and is arranged between the photoactive layer and the carrier. The substrate and the carrier can be made of the same material.

摘要： Disclosed is a method for producing coated substrates, wherein a first aqueous suspension and a second aqueous suspension are produced, a layer of the first aqueous suspension is applied onto a substrate, a layer of the second aqueous suspension is applied onto the layer of the first aqueous suspension applied onto the substrate, and the resulting substrate coated is sintered. The first and second aqueous suspensions each contains a refractory metal carbide, a sinter additive and water. Additionally, the second aqueous suspension can contain a sinter additive, wherein the content by weight percentage of the sinter additive in the second aqueous suspension, based on the total weight of the second aqueous suspension, is less than the content by weight percentage of the sinter additive in the first aqueous suspension, based on the total weight of the first aqueous suspension. Also disclosed are a coated substrate produced using the method and the use of the coated substrate.

摘要： The invention relates to an optical microlens array and to a method for manufacturing an optical microlens arrays, wherein the method includes, among other things: providing a substrate having a first side and an opposite second side. The method further includes applying a photoresist to the first side of the substrate at least in portions, and structuring the photoresist such that the structured photoresist remains at predetermined locations on the first side of the substrate where one optical microlens each is to be later arranged. In addition, the method includes applying a hydrophobic coating to the first side of the substrate and subsequently removing the structured photoresist including the hydrophobic coating located thereon from the first side of the substrate. Furthermore, according to the invention, one microlens each is arranged on the spots of the first side of the substrate that are freed from the structured photoresist.
