US 2026/0230207 A1 · PROCEDURES TO INFORM THE G-NB FOR CSI REQUIREMENTS

Abstract

The WTRU may use the reference signals received during a look-ahead window to determine a CSI prediction accuracy (α) by computing the relative difference between the measured CSI and the predicted CSI with respect to received CSI-RSs. The WTRU compares the current measured CSI prediction accuracy in the look-ahead window i to a configured prediction accuracy threshold to determine the preferred number of CSI-RS K(i+1) to receive in the next look-ahead window i+1. If the determined accuracy is high, relative to a minimum threshold, the number of CSI-RS transmissions may be reduced in the next look-ahead window. If the determined prediction accuracy is low, relative to the minimum threshold, the WTRU may request an increased number reference signals for the next look-ahead window for improving the accuracy of prediction in the next, or set, of look-ahead window(s). Updated predicted CSI and accuracies may be reported to the gNB.
