1. A method implemented by a network node, the method comprising:
transmitting a first signal to a wireless transmit receive unit (WTRU), the first signal comprising control information indicating a number of scheduled resource blocks (RBs); and
transmitting a second signal to the WTRU, the second signal comprising phase tracking reference signals (PT-RSs), wherein the PT-RSs are transmitted via the scheduled RBs, a density of the PT-RSs is based on the number of scheduled RBs, and a RB offset value for the PT-RSs is based on a WTRU identity (WTRU-ID) modulo a maximum RB offset value, the maximum RB offset value being based on the density of the PT-RSs.
