Abstract: A wireless transmit/receive unit (WTRU) may receive a downlink transmission and send a physical uplink control channel (PUCCH) transmission in each resource block (RB) of an interlace of a plurality of RBs in an active bandwidth part (BWP). A base sequence is mapped to the PUCCH transmission repetitively, once to each RB of the plurality of RBs of the interlace, using a different cyclic shift of the base sequence for each RB. Each different cyclic shift of the base sequence in the PUCCH transmission to each RB is a function of a RB index of the respective RB. The PUCCH transmission indicates either an acknowledgement (ACK) or a negative ACK (NACK) of the received downlink transmission.

Abstract: A method for transmitting a discrete fourier transform (DFT) DFT-S-OFDM signal including frequency domain reference symbols is disclosed. The method comprises: determining to null a plurality of data symbols prior to DFT-spreading; performing DFT-spreading including the determined null data symbols; puncturing an interleaved output of the DFT-spreading; inserting reference symbols in a frequency domain of the punctured and interleaved DFT-S-OFDM signal; and transmitting the DFT-S-OFDM signal with inserted reference symbols to a receiver. The transmitted DFT-S-OFDM signal enables the receiver to apply zeros corresponding to the reference symbols to an interleaved input of DFT-despreading, and cancel interference due to the puncturing by using all outputs of the DFT-despreading.

Abstract: According to an example embodiment, a stereoscopic near-eye display (NED) assembly for a NED device including a pair of NED assemblies is provided, where an input image is subjected to a preprocessing procedure that applies image-area-position dependent preprocessing before providing it for viewing through a lens assembly that comprises a diffractive optical element (DOE) arranged to provide a phase delay that is different through a plurality of positions of its aperture. According to other example embodiments, an apparatus and a method for deriving the preprocessing procedure and the DOE are provided.

Abstract: The invention provides a system for the preshearing based control of the flow and deformation behavior, i.e., the setting kinetics, and the time dependent shear viscosity, elasticity of aqueous cementitious suspensions that can be used for bone repair and regeneration. The dynamic cement microstructure is tailored to the demands of the surgical tasks (faster/slower setting) or additive manufacturing tasks (lower/higher viscosity) by application of various preshearing conditions. Since the relationships between the preshearing and pressurization conditions and the setting kinetics and the time dependent changes in elasticity and viscosity are complex, a priori characterization of viscoelastic properties using the advanced rheological characterization technique of small-amplitude oscillatory rheometry is needed to enable such tailoring.
