Abstract: Various embodiments provide techniques for channel state information reference signal (CSI-RS) transmission in a wireless cellular network. CSI-RS transmission bandwidth is determined based on a frequency domain allocation of a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), or a physical downlink control channel (PDCCH). A user equipment (UE) receives the CSI-RS according to the frequency domain allocation and a time domain allocation.

Abstract: Various embodiments herein are directed to determining phase tracking reference signal (PT-RS) patterns, including systems operating above a carrier frequency of 52.6 GHz and an apparatus comprising: memory to store phase tracking reference signal (PT-RS) information for initial transmission and retransmission of a transport block (TB) within a physical uplink shared channel (PUSCH); and processing circuitry, coupled with the memory, to: retrieve the PT-RS information from the memory; and encode a PUSCH containing the TB for initial transmission or retransmission based on the PT-RS information.

Abstract: A computer-readable storage medium stores instructions to configure a UE for operation in a 5G NR and beyond wireless network and to cause the UE to perform operations. The operations include encoding a data bitstream to generate a plurality of code blocks. Code block interleaving of a subset of code blocks of the plurality of code blocks is performed to generate an interleaved bitstream. The interleaved bitstream is modulated using a discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) to generate multiple sets of time-domain samples. The operations further include causing transmission of the multiple sets of time-domain samples.

Abstract: Various embodiments herein provide techniques for enhanced bit mapping for transmission of control information (e.g., uplink control information (UCI) and/or downlink control information (DCI)). Other embodiments may be described and claimed.

Abstract: Herein described are apparatuses, systems, and methods for measurement and reporting of channel state information within wireless network systems. In embodiments, an apparatus for a user equipment (UE) may include memory to store a rank indicator (RI), a precoding matrix index (PMI), and a channel quality indicator (CQI) of channel state information (CSI) for the UE. The apparatus may further include circuitry to concatenate the RI, the PMI, and the CQI to produce a concatenated CSI element, generate a CSI report that includes the concatenated CSI element, and cause the CSI report to be transmitted to a base station within a single slot. Other embodiments may be described and/or claimed.

Abstract: Systems, devices, and techniques associated with coefficients for channel state information (CSI) reports are described. A described technique includes receiving, at a user equipment (UE), a CSI configuration and a codebook configuration, the codebook configuration specifying a codebook; determining a precoding matrix indicator (PMI) that specifies a precoding matrix associated with the codebook, wherein the precoding matrix is based on spatial-domain (SD) vectors and linear combining coefficients; and transmitting a CSI report containing the PMI in accordance with the CSI configuration.

Abstract: The present invention relates to the use of an additive which is an aqueous system of specific polyether silicones in clinker and cement preparation. The additive improves the grinding efficiency and also results in an improvement in the cured properties of cementitious compositions employing cement so produced.
