1. A method for a network-controlled repeater (NCR), the method comprising:
receiving, by an NCR mobile termination (NCR-MT) entity:
first information for a list of spatial domain filters for an access link of an NCR forwarding (NCR-Fwd) entity corresponding to a list of time domain resources,
second information for a set of spatial relations corresponding to reference signals (RSs) for transmission or reception on a control link (C-link) of the NCR-MT entity, and
third information indicating an uplink (UL) direction or a downlink (DL) direction for each time domain resource from the list of time domain resources;
determining, by the NCR-MT entity:
an UL time domain resource from the list of time domain resources based on the third information,
a first spatial domain filter from the list of spatial domain filters, and
a second spatial domain filter based on the second information;
receiving, by the NCR-Fwd entity, a radio frequency (RF) signal on the access link using the first spatial domain filter over the UL time domain resource;
amplifying, by the NCR-Fwd entity, the RF signal; and
transmitting, by the NCR-Fwd entity, the RF signal on a backhaul link of the NCR-Fwd entity using the second spatial domain filter over the UL time domain resource.
