1. A base station comprising a processor and a memory, the processor and the memory configured to:
send an indication to transmit one or more phase noise reference signals;
send downlink control information (DCI) that includes an indication of a set of uplink resources for an uplink transmission and an indication of a modulation coding scheme;
determine a phase noise reference signal (PNRS) density associated with the uplink transmission, wherein the PNRS density is determined based at least on the indicated modulation coding scheme; and
receive the uplink transmission via the set of uplink resources, wherein the set of uplink resources comprises a first subset of the set of uplink resources that is used for reception of one or more phase noise reference signals, wherein the first subset of the set of uplink resources is comprised in a subset of a plurality of resource blocks (RBs), and wherein the subset of the plurality of RBs that comprise the first subset of the set of uplink resources is determined based on at least a wireless transmit receive unit identifier (WTRU-ID).
