    Abstract: A method and device for self-tuning scales of variables for processing in fixed-point hardware. The device includes a sequence of fixed-point arithmetic circuits configured to receive at least one input signal and output at least one output signal. The circuits are preconfigured with control scales associated with each of the input and output signals. A first circuit in the sequence is configured to receive a first input signal having a dynamic true scale that is different from the control scale associated with the first input signal. Each of the circuits is further configured to determine, for each of the output signals, an adaptive scale from the control scale associated with the output signal based on the true scale of the first input signal and the control scale associated with the first input signal, and generate, from the input signal, the output signal having the associated adaptive scale.

    Abstract: A base station (UE) is configured to perform a computer-implemented method for antenna fault detection and correction. The computer-implemented method includes acquiring one or more sounding reference signals (SRSs) received from at least one gNB antenna; detecting an antenna failure based on the one or more SRSs; estimating a noise power based on the antenna failure and a history of received SRSs; detecting a missing SRS based on the noise power and the history of received SRSs; and handling the missing SRS. Handling the missing SRS is based on performing at least one of: replacing an SRS measurement with a predicted SRS value for the missing SRS when the predicted SRS is available; or avoiding use of the missing SRS in a sequential SRS prediction when the predicted SRS is unavailable.

    Abstract: The method comprises receiving periodic CSI feedback configuration information including a periodicity value and an offset value corresponding to a first CSI report, and at least one periodicity value and at least one offset value corresponding to a second CSI report, measuring a first CSI reference signal (CSI-RS) and a second CSI-RS configured for a periodic CSI reporting based on at least two different enhanced MIMO types (eMIMO-Types), generating the first CSI report and the second CSI report for the first eMIMO-Type and the second eMIMO-Type, respectively, determining a periodic reporting interval for each of the first CSI report and the second CSI report, and reporting the first and second CSI reports based on the determined periodic reporting intervals using a physical uplink control channel (PUCCH) format 2 or a PUCCH format 3 or a combination of the PUCCH format 2 and the PUCCH format 3.

    Abstract: A base station capable of communicating with a user equipment (UE) includes a transceiver configured to transmit 8-port Channel State Information-Reference Signal (CSI-RS) according to a CSI-RS configuration for the UE, and downlink signals containing the CSI-RS configuration on physical downlink shared channels (PDSCH), and receive, from the UE, uplink signals containing Precoder Matrix Indicator (PMI) derived using the 8-port CSI-RS, and a controller configured to convert the PMI to one of predetermined precoding vectors. A user equipment includes a transceiver configured to receive downlink signals containing a CSI-RS configuration on PDSCH transmitted by the BS, and 8-port CSI-RS according to the CSI-RS configuration, and transmit uplink signals containing a PMI, a controller configured to decode the CSI-RS configuration from the downlink signals, and derive the PMI by utilizing channel estimates based on the 8-port CSI-RS, the PMI mapped to one of precoding vectors.
