摘要： Provided is a semi-transparent display and a method for producing a semi-transparent display. An SOI wafer is provided, the surface having at least one pixel region and at least one contact region arranged next to the pixel region, the SOI wafer comprising a silicon substrate on the rear side. At least one electromagnetic-radiation-emitting layer is deposited on the front side of the SOI wafer. At least one transparent cover layer is applied above the at least one electromagnetic-radiation-emitting layer. A wiring carrier is fastened to the assembly comprising the SOI wafer, the electromagnetic-radiation-emitting layer and the transparent cover layer. Before fastening of the wiring carrier to the assembly, the silicon substrate is removed from the assembly, producing a residual assembly, and electrically conductive connections are formed between the contact region of the SOI wafer and the wiring carrier from the rear side of the SOI wafer.

The UE is operative to: estimate the MIMO channel between the gNB and the UE based on received DL reference signals for the configured resource blocks. The UE is further operative to calculate, based on a performance metric, a precoder matrix, for a number of antenna ports of the gNB and configured subbands, the precoder matrix being based on two codebooks and a set of combination coefficients for complex scaling/combining one or more of vectors selected from a first codebook and a second codebook, and the UE is operative to report a CSI feedback and/or a PMI and/or a PMI/RI, to the gNB, used to indicate the precoder matrix for the configured antenna ports and resource blocks.
