Tone-level interleaving and de-interleaving for broadcast or multicast communications

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:
• receive, from a base station, a channel for multicast or broadcast communications;
• perform tone-level de-interleaving of tone-level interleaved tones of the channel in a frequency domain;
• and
• obtain a plurality of code blocks of a transport block of the channel having a transport block size (TBS) based on the de-interleaving.
