Wireless transmit/receive unit signaling and procedures for network side data collection

A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:

• receiving configuration information, wherein the configuration information indicates information related to ground-truth reporting, and wherein the information related to ground-truth reporting comprises data quality criteria, a data quality indicator configuration, and a threshold associated with ground-truth filtering;
• determining a plurality of ground-truth samples based on one or more received reference signals;
• determining one or more metrics associated with the plurality of ground-truth samples based on the data quality criteria;
• determining one or more data quality indicators associated with the plurality of ground-truth samples based on the one or more metrics and the data quality indicator configuration;
• determining a subset of ground-truth samples of the plurality of ground-truth samples based on the one or more data quality indicators, the threshold associated with ground-truth filtering, and the plurality of ground-truth samples;
• and
• sending the subset of ground-truth samples to a network entity.
