13. An apparatus comprising:
a processing system that includes one or more processors and one or more memories coupled with the one or more processors, the processing system configured to cause the apparatus to:
receive a configuration from a network for uplink transmission according to an uplink frequency allocation;
receive an instruction from the network identifying a frequency area associated with a sidelink communication for interference cancellation with respect to the uplink frequency allocation;
modulating a plurality of symbols on the uplink frequency allocation and on a plurality of interference cancellation subcarriers based on the frequency area
transmit a sidelink waveform to a second apparatus; and
transmit a waveform to the network, the waveform including the plurality of symbols without applying interference cancellation to an automatic gain control (AGC) symbol of the sidelink communication.
