In another aspect, two or more grants are grouped together, with the respective group being mapped to a PUCCH. ## Claims ### Claim 1 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;
