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: In embodiments, a base station may identify a parameter related to a zero power (ZP) resource element (RE) mapping set in a physical resource block (PRB). The ZP RE mapping set may relate to resources that are not to be used to transmit a physical channel transmission. The base station may then transmit, to a user equipment (UE), an indication of the ZP RE mapping set. Other embodiments may be described and/or claimed.

Abstract: Network devices and systems in 5G advance long term evolution (LTE) and new radio (NR) infrastructures utilize beam management operations to ensure communications for channel state information (CSI) reporting by a user equipment (UE). CSI report configuration reporting settings are processed based on a codebook subset restriction to indicate pre-coding matrix indicators (PMIs) that are restricted and non-restricted for PMI reporting associated with a rank indicator (RI). Based on the codebook subset restriction, an advanced CSI codebook or a new radio (NR) codebook is generated to be transmitted on non-restricted beams of the codebook subset restriction.

Abstract: Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may map data symbols to resource elements (REs) of virtual resource blocks (VRBs). The gNB may interleave the data symbols, on a per-VRB basis, to spatial layers of a multi-layer multiple-input multiple-output (MIMO) transmission. The data symbols may be interleaved based on different interleave patterns of VRB indexes for the spatial layers. The gNB may map the interleaved data symbols of the spatial layers to REs of physical resource blocks (PRBs) for orthogonal frequency division multiplexing (OFDM) transmission.

Abstract: Some embodiments of this disclosure include apparatuses and methods for reporting channel state information (CSI) for multiple spatial layers. The apparatuses and methods can include at least: determining, by a user equipment (UE), a precoding matrix indicator (PMI) for a set of precoding matrixes, wherein the PMI is determined based on a combination of digital Fourier transformation (DFT) spatial domain (SD) vectors, or based on DFT-based frequency domain (FD) compression; and transmitting, by the UE, the PMI to a next-generation NodeB (gNB).

The apparatus includes a first circuitry and a second circuitry. The first circuitry may be operable to determine a first parameter set and a second parameter set for establishing Physical Downlink Shared Channel (PDSCH) resources. The second circuitry may be operable to process a first part of a PDSCH transmission from a first set of Multiple Input Multiple Output (MIMO) layers corresponding with a first Multimedia. Broadcast Single Frequency Network (MBSFN) configuration based on the first parameter set. The second circuitry may also be operable to process a second part of the PDSCH transmission from a second set of MIMO layers corresponding with a second MBSFN configuration based on the second parameter set.
