1. An apparatus for wireless communications at a user equipment (UE), comprising:
one or more processors; and
one or more memories coupled with the one or more processors and storing instructions executable by the one or more processors to cause the apparatus to:
receive, system information indicating a numerology, a reference signal (RS) pattern, and a modulation and coding scheme (MCS) associated with a broadcast or multicast service;
determine an initial transport block size (TBS) based at least in part on the numerology, the RS pattern, and the MCS;
scale the initial TBS using a scaling factor based at least in part on the numerology indicating that an orthogonal frequency division multiplexing (OFDM) symbol associated with the broadcast or multicast service spans multiple subframes;
select, based at least in part on the scaled initial TBS, a TBS from a set of TBSs; and
receive the broadcast or multicast service via a multicast channel in accordance with the TBS.
