Handling interference in multi-radio access technology (RAT) wireless transmit/receive unit (WTRU)

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

• receiving information that indicates a first set of downlink resources associated with a downlink transmission that uses a New Radio (NR) radio access technology, wherein at least a portion of spectrum utilized by the NR radio access technology is shared with a Long Term Evolution (LTE) radio access technology;
• receiving, from a base station via a transceiver using the NR radio access technology, configuration information associated with the LTE radio access technology, wherein the configuration information received using the NR radio access technology indicates cell-specific reference signal transmission information for the LTE radio access technology;
• determining that a subset of the first set of downlink resources associated with the downlink transmission that uses the NR radio access technology overlaps with a second set of resources associated with a cell-specific reference signal transmission for the LTE radio access technology based on the cell-specific reference signal transmission information for the LTE radio access technology indicated by the configuration information received using the NR radio access technology;
• and
• receiving, from the base station via the transceiver, the downlink transmission that uses the NR radio access technology,
• wherein the downlink transmission is not received on the subset of the first set of downlink resources on the NR radio access technology that overlaps with the second set of resources associated with the cell-specific reference signal transmission for the LTE radio access technology.
