Abstract
The present disclosure describes methods, systems and devices for switching cross-carrier scheduling primary cell for a user equipment (UE), wherein a secondary cell is configured to schedule the primary cell. One method includes receiving, by the UE, a downlink control information (DCI) via a physical downlink control channel (PDCCH) from a network base station, the DCI used to switch the cross-carrier scheduling primary cell. Another method includes receiving, by the UE, a medium access control (MAC) control element (CE) from a network base station, the MAC CE used to switch the cross-carrier scheduling primary cell. Another method includes performing switching off cross-carrier scheduling primary cell by a secondary cell for a UE, and restoring, by the UE, a factor in the primary cell for scheduling the primary cell, and/or restoring, by the UE, a non-fallback downlink control information (DCI) in the primary cell for scheduling the primary cell.
