    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: Technology for an UE operable to report channel state information (CSI) for multi-user superposition transmissions (MUST) is disclosed. The UE can process a plurality of power offset parameters that are received from an eNodeB, for the MUST. The UE can perform a downlink channel measurement at a user equipment (UE). The UE can scale the downlink channel measurement using at least one of the plurality of power offset parameters to form one or more scaled downlink channel measurements. The UE can calculate CQI values for the one or more scaled downlink channel measurements. The UE can process, for transmission to the eNodeB, the CQI values for the one or more scaled downlink channel measurements to enable the UE to receive data on a physical downlink shared channel (PDSCH) using multi-user superposition transmission.

    Abstract: Methods and apparatuses for communicating in a cellular communications network, including provision of a user equipment comprising processing circuitry to: replace one or more transmission parameters from which a further transmission parameter may be determined with one or more corresponding virtual transmission parameters to provide one or more replacement transmission parameters from which a modified further transmission parameter may be determined; determine the modified further transmission parameter based on the one or more replacement transmission parameters; and transmit a signal using the modified further transmission parameter.

    Abstract: Embodiments of an eNB to operate in accordance with a coverage enhancement mode are disclosed herein. The eNB may comprise hardware processing circuitry to, during a legacy sub-frame, transmit a system information block (SIB) in legacy SIB frequency resources according to a legacy SIB transmission format and refrain from transmission of channel state information reference signals (CSI-RS). The hardware processing circuitry may be further to, during a first coverage enhancement sub-frame, transmit a first portion of the SIB in first SIB frequency resources included in the legacy SIB frequency resources. The hardware processing circuitry may be further to, during a first coverage enhancement sub-frame, transmit a first set of CSI-RS in first CSI-RS frequency resources that include at least a portion of the legacy SIB frequency resources.

    Abstract: Aperiodic channel state information (CSI) reporting is discussed. An example user equipment includes a receiver circuit, processor, and transmitter circuit. The receiver circuit receives transmissions from a plurality of serving cells via a carrier aggregation (CA) mode and receives an aperiodic CSI reporting request indicating a set for CSI reporting. The plurality of serving cells comprises at least six serving cells, and one or more of the plurality is associated with the indicated set. The processor is operably coupled to the receiver circuit and calculates one or more CSI parameters for each serving cell of the plurality that is associated with the indicated set; and generates an aperiodic CSI report based at least in part on the calculated CSI parameters for each serving cell associated with the indicated set. The transmitter circuit transmits the aperiodic CSI report to an Evolved NodeB (eNB) via a physical uplink shared channel (PUSCH).
