US 2021/0243745 A1 · SLOT POSITION OFFSETS ASSOCIATED WITH A DOWNLINK CONTROL INFORMATION IN A PHYSICAL DOWNLINK SHARED CHANNEL

Abstract

In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDCCH includes a first DCI part and the PDSCH includes a second DCI part (e.g., a 2-part DCI). In an example a first grant associated with the second DCI part is offset relative to a slot position of the second DCI part, whereas a second grant associated with the second DCI part is offset relative to the slot position to which the first grant is offset. In another aspect, two or more grants are grouped together, with the respective group being mapped to a PUCCH.

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;
determining, for a first of a plurality of grants, a first slot position that is offset by a first slot level offset relative to a slot position of the second part of the DCI in the PDSCH;
determining, for a second of the plurality of grants, a second slot position that is offset by a second slot level offset relative to the first slot position;
and
transmitting the PDCCH and the PDSCH during the at least one slot.
