1. A method implemented in a wireless transmit/receive unit (WTRU) for wireless communications, the method comprising:
receiving configuration information of one or more reference signal (RS) resource sets, wherein the configuration information indicates a set of slot offset deltas that is associated with at least one RS resource set of the one or more RS resource sets is associated with a slot offset;
receiving downlink control information (DCI) indicating an RS request, wherein the RS request indicates the at least one RS resource set of the one or more RS resource sets, wherein the DCI comprises a field for indicating slot offset delta;
determining a slot offset delta from the set of slot offset deltas based on the field for indicating slot offset delta;
determining a slot for transmitting an RS based on at least the determined slot offset delta; and
transmitting the RS in the determined slot.
