Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a multi-cell downlink control information (MC-DCI) that via a scheduling cell may schedule communications for more than one scheduled cells. The overhead of a DCI (e.g., an MC-DCI) may be reduced by compressing or removing the carrier indication field (CIF). For example, radio resource control signaling may indicate, to a UE, a DCI payload size, control channel elements (CCE)s, and/or physical downlink control channel (PDCCH) candidates per scheduled cell or per group of scheduled cells. If the DCI payload sizes, CCEs, and/or PDCCH candidates are different for the scheduled cells indicated in the radio resource control message, the UE may determine to which scheduled cell(s) a DCI received in a PDCCH monitoring occasion applies based on the payload size and/or CCEs of the PDCCH monitoring occasion without using a CIF.
