Abstract
A communication apparatus including: a controller configured to configure a plurality of SCells including a first SCell carrying a PUCCH and a second SCell different from first SCell; and a transmitter configured to transmit to a network side via a Physical Uplink Channel (PUCCH) a uplink control information (UCI) using the first SCell; wherein the controller configures a deactivation timer with respect SCell except for the first SCell among the plurality of SCells, and the controller configures the first SCell to be activated and deactivated by an activation/deactivation media access control (MAC) control element (CE).
Claims17
A communication apparatus comprising:
- a receiver configured to receive a signal comprising configuration information that indicates configuration of a plurality of SCells comprising a first SCell carrying a physical uplink control channel (PUCCH) and a second SCell different from the first SCell,
- wherein the configuration information comprises PUCCH configuration information for the first SCell and deactivation timer information for the second SCell;
- a controller configured to configure the plurality of SCells comprising the first SCell carrying the PUCCH and the second SCell according to the configuration information,
- wherein the controller configures a deactivation timer for the second SCell according to the deactivation timer information, and the controller configures the first SCell to be activated or deactivated by an activation/deactivation media access control (MAC) control element (CE);
- and
- a transmitter configured to transmit to a network side via a Physical Uplink Channel (PUCCH) uplink control information (UCI) using the first SCell.
A network device comprising:
- a transmitter configured to transmit to a communication device a signal comprising configuration information that indicates configuration of a plurality of Scells comprising a first SCell carrying a PUCCH and a second SCell different from the first SCell;
- and
- a receiver configured to receive from the communication device via a Physical Uplink Channel (PUCCH) uplink control information (UCI) using the first SCell;
- wherein the configuration information comprises a deactivation timer with respect to an SCell except for the first SCell among the plurality of SCells, and
- the transmitter transmits an information comprising an activation/deactivation media access control (MAC) control element (CE).
A method comprising:
- receiving a signal comprising configuration information that indicates configuration of a plurality of SCells comprising a first SCell carrying a physical uplink control channel (PUCCH) and a second SCell different from the first SCell, the configuration information comprises PUCCH configuration information for the first SCell and deactivation timer information for the second SCell;
- configuring the plurality of Scells comprising the first SCell carrying the PUCCH and the second SCell according to the configuration information;
- configuring a deactivation timer for the second SCell according to the deactivation timer information;
- configuring the first SCell to be activated or deactivated by an activation/deactivation media access control (MAC) control element (CE);
- and
- transmitting to a network side via a Physical Uplink Channel (PUCCH) uplink control information (UCI) using the first SCell.
