US 2021/0243789 A1 · PHYSICAL DOWNLINK SHARED CHANNEL INCLUDING PART OF A DOWNLINK CONTROL INFORMATION

Abstract

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.

Claims30

Dependent claims

A method of operating a base station, comprising:

scheduling, during at least one slot, transmission of a Physical Downlink Control Channel (PDCCH) and a Physical Downlink Shared Channel (PDSCH), the PDCCH including a first part of a Downlink Control Information (DCI), the PDSCH including a second part of the DCI, wherein the scheduling includes determining a transport block size (TBS) associated with the PDSCH;
and
transmitting the PDCCH and the PDSCH during the at least one slot,
wherein the PDSCH is transmitted in accordance with the determined TBS.
