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.

1. An electronic device, comprising
processing circuitry, configured to
configure a plurality of secondary cells for carrier aggregation; andactivate/deactivate at least one of the plurality of secondary cells based on a combination of an implicit manner and an explicit manner, whereinthe processing circuitry is further configured to activate the at least one of the plurality of secondary cells in an uplink in the explicit manner using a first activation command according to a certain inter-band carrier aggregation scenario in which each of a plurality of component carriers is received by a separate radio frequency chain,the processing circuitry is further configured to activate the at least one of the plurality of secondary cells in the uplink in the implicit manner in response to a second activation command for the associated downlink carrier according to another scenario that is different from the certain inter-band carrier aggregation scenario, andthe first activation command is different from the second activation command for an associated downlink.
