Patent ID: 11855784

Abstract:
Aspects of the disclosure relate to devices and methods for managing carrier aggregation. Downlink control information (DCI), transmitted via a primary cell (PCell), may include one or more secondary cell (SCell) dormancy indication (SDI) value(s) for one or more secondary cells (SCells). That DCI may also schedule a physical downlink shared channel. A scheduled entity may transmit acknowledgment information indicating whether the scheduled entity successfully received the DCI. Where the SDI indicates a switch in behavior relative to one or more SCell(s) and the acknowledgment information indicates that the scheduled entity successfully received that DCI, the one or more SCell(s) transition from dormant to active or vice-versa. Accordingly, the scheduled entity conforms its behavior to provide the appropriate dormancy and non-dormancy behavior when utilizing, in addition to the PCell, one or more SCell(s) for wireless communication in carrier aggregation.
