1. A wireless transmit/receive unit (WTRU) comprising:
a transceiver; and
a processor, wherein the processor is configured to:
receive, from a base station via the transceiver, 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, resources of the LTE radio access technology are associated with a 15 kHz subcarrier spacing, a first set of frequency resources associated with the 5G NR radio access technology are associated with a first subcarrier spacing, and a second set of frequency resources associated with the 5G NR radio access technology are associated with a second subcarrier spacing;
receive, from the base station via the 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 and a multicast-broadcast single-frequency network (MBSFN) subframe configuration of the LTE radio access technology;
determine 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 and the MBSFN subframe configuration of the LTE radio access technology indicated by the configuration information received using the NR radio access technology;
receive, from the base station via the transceiver, the downlink transmission that uses the NR radio access technology; and
puncture the downlink transmission 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.
