Abstract
Procedures, methods, architectures, apparatuses, systems, devices, and computer program products that may be implemented in a wireless transmit/receive unit (WTRU) and/or a network access point (NAP) with respect to MIMO precoding using a precoding neural network (NN) at the NAP. Training of the NN may use artificial and/or measured channel state information (CSI). In one embodiment, the WTRU may provide feedback to the NAP in the form of CSI statistics, time correlation, and/or bit error rate (BER) regarding a channel. The NAP may inform the WTRU of information for extracting training samples which are fed back from the WTRU to the NAP. The NAP may perform retraining of the NN using the training samples to adjust and/or recalibrate the NN weights. The information for extracting training samples may include CSI reference signal (CSI-RS) density and/or CSI-RS transmission time slots for extracting the training samples at the WTRU.
