1. An apparatus for wireless communication, comprising:
a transceiver;
a memory configured to store instructions; and
one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to:
transmit, to a network node, an indication of a capability to support using one phase tracking reference signal (PTRS) for performing phase compensation for multiple configured component carriers (CCs);
receive, from the a-network node and based on the indication of the capability, a configuration indicating a reduced number of the multiple configured CCs over which to process one or more PTRSs for performing phase compensation for the multiple configured CCs;
receive, over the reduced number of the multiple configured CCs, the one or more PTRSs; and
perform, based on the one or more PTRSs, phase compensation for the multiple configured CCs.
