Method and apparatus for processing activation/deactivation of inter-eNodeB carrier aggregation
The present invention relates to the technical field of radio communications, and particularly to a method and apparatus for processing activation/deactivation of inter-eNodeB carrier aggregation. Embodiments of the present invention provide a method for processing activation/deactivation of inter-eNodeB carrier aggregation, comprising the steps of: receiving, by UE, an MAC CE for activation/deactivation of an SCell sent by a master eNodeB or a secondary eNodeB; determining, by the UE, the corresponding SCell; and performing, by the UE, activation/deactivation to the corresponding SCell according to the indication information in the MAC CE for activation/deactivation.
1. A method for processing a carrier aggregation by a terminal, the method comprising:
receiving, from a base station, a first message for adding a secondary cell (SCell) of a master cell group (MCG), the first message including a first SCellIndex for an SCell of the MCG;
receiving, from the base station, a second message for adding an SCell of a secondary cell group (SCG), the second message including a second SCellIndex for the SCell of the SCG;
receiving, from the base station, a third message for activating/deactivating of an SCell among the SCell of the MCG and the SCell of the SCG; and
activating/deactivating the SCell identified based on the first SCellIndex and the second SCellIndex.
2. The method of claim 1 , wherein the SCell to be activated/deactivated is indicated by at least one bit of the third message.
3. The method of claim 2 , wherein each of the at least one bit corresponds to an SCellIndex of one SCell among the SCell of the MCG and the SCell of the SCG.
4. The method of claim 1 , wherein the first SCellIndex and the second SCellIndex are allocated uniquely for the terminal.
5. The method of claim 1 , wherein the third message indicates whether to activate or deactivate the SCell identified based on the first SCellIndex and the second SCellIndex.
6. A terminal for processing a carrier aggregation, the terminal comprising:
a transceiver configured to transmit and receive signals; and
a controller coupled with the transceiver and configured to:
control the transceiver to receive, from a base station, a first message for adding a secondary cell (SCell) of a master cell group (MCG), the first message including a first SCellIndex for the SCell of the MCG,
control the transceiver to receive, from the base station, a second message for adding an SCell of a secondary cell group (SCG), the second message including a second SCellIndex for the SCell of the SCG;
control the transceiver to receive, from the base station, a third message for activating/deactivating of an SCell among the SCell of the MCG and the SCell of the SCG; and
activate/deactivate the SCell identified based on the first SCellIndex and the second SCellIndex.
7. The terminal of claim 6 , wherein the SCell to be activated/deactivated is indicated by at least one bit of the third message.
8. The terminal of claim 7 , wherein each of the at least one bit corresponds to an SCellIndex of one SCell among the SCell of the MCG and the SCell of the SCG.
9. The terminal of claim 6 , wherein the first SCellIndex and the second SCellIndex are allocated uniquely for the terminal.
10. The terminal of claim 6 , wherein the third message indicates whether to activate or deactivate the SCell identified based on the first SCellIndex and the second SCellIndex.
