In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDDCH includes a first DCI part and the PDSCH includes a second DCI part. In an example, a TBS associated with the PDSCH may be determined (e.g., either by factoring or ignoring resource elements associated with the second DCI part). In another example, the PDSCH may be associated with a modulation scheme with a constellation having constellation points, whereby the second DCI part in the PDSCH is restricted to a subset of the constellation points. In another example, rate-matching may be performed for one or more resource elements of the second DCI part.
