Method and device for activating and de-activating uplink of secondary cell of terminal

摘要

An electronic device, including processing circuitry, configured to configure a plurality of secondary cells for carrier aggregation and activate/deactivate at least one of the plurality of secondary cells based on a combination of an implicit manner and an explicit manner. The processing circuitry is further configured to activate the at least one of the plurality of secondary cells in an uplink in the explicit manner according to a certain inter-band carrier aggregation scenario in which component carriers are received by separate radio frequency chains.
