    Abstract: User equipment (UE) includes processing circuitry coupled to memory. To configure the UE for channel state information (CSI) reporting in a 5G network, the processing circuitry is to decode a radio resource control (RRC) configuration message, the RRC configuration message including first configuration information to configure determination of channel quality information (CQI), a rank indicator (RI), and a precoding matrix indicator (PMI) for the CSI reporting. Second configuration information is decoded to configure codebook parameters for a high spatial resolution codebook associated with the PMI. A precoding matrix is determined based on the first configuration information, where a number of coefficients in at least one coefficient vector of the precoding matrix is configured using the second configuration information. CSI is encoded for transmission to a base station, the CSI including the RI and the PMI associated with the determined precoding matrix.

    Abstract: Described is an apparatus of a User Equipment (UE) operable to communicate with a fifth generation Evolved Node-B (gNB) on a wireless network. The apparatus may comprise 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.

    Abstract: An approach is described that includes receiving a CSI report, where the CSI report includes a channel quality indicator (CQI), a rank indicator (RI), and a precoding matrix indicator (PMI). The approach further includes constructing a precoding matrix based on a linear combination of a plurality of mutually orthogonal digital Fourier transformation (DFT) spatial beams, and determining a number of bits for the PMI of the precoding matrix. The approach also includes determining a space frequency matrix based, at least in part, on the number of bits for the PMI and the precoding matrix, and compressing the space frequency matrix. Finally, the approach includes determining a compressed PMI based, at least in part, on the space frequency matrix.

    Abstract: This disclosure proposes to use multiple power control loops in the uplink. Each power control loop may be associated with a respective antenna beam transmitted from an antenna array of the electronic device (e.g. UE) in the uplink. For example, a beam (or uplink signal) may be associated with 1, 2 or even more MIMO layer. Hence, in this latter case, each power control loop may be associated with a respective set of one or more MIMO layers. This concept is application to open-loop, closed-loop power control or both.

    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.
