Abstract
A method and apparatus for receiving a control signal in a wireless communication system in which a plurality of cells are merged. The method includes: receiving a signal indicating a deactivation of at least one cell from among the plurality of cells; and deactivating the at least one cell. The deactivation-indicating signal indicates the deactivation of the at least one cell to all of a plurality of user equipments configured to merge the at least one cell.
Claims11
A method for receiving a control signal by a user equipment (UE) in a wireless communication system in which a plurality of cells are aggregated, the method comprising:
- receiving a signal indicating deactivation of at least one cell among the plurality of the cells;
- and
- deactivating the at least one cell,
- wherein the signal indicating the deactivation commonly indicates the deactivation of the at least one cell to a plurality of UEs configured to aggregate the at least one cell, and
- wherein the receiving the signal indicating the deactivation includes detecting a PDCCH scrambled with a radio network temporary identifier (RNTI) common to the plurality of UEs and receiving a physical downlink shared channel (PDSCH) scheduled by the PDCCH, and wherein the signal indicating the deactivation is received via the PDSCH.
A user equipment (UE) for receiving a control signal in a wireless communication system in which a plurality of cells are aggregated, the UE comprising:
- a radio frequency (RF) unit;
- and
- a processor, the processor configured to receive a signal indicating deactivation of at least one cell among the plurality of cells through the RF unit, and deactivate the at least one cell,
- wherein the signal indicating the deactivation commonly indicates the deactivation of the at least one cell to a plurality of UEs configured to aggregate the at least one cell, and
- wherein the receiving the signal indicating the deactivation includes detecting a PDCCH scrambled with a radio network temporary identifier (RNTI) common to the plurality of UEs and receiving a physical downlink shared channel (PDSCH) scheduled by the PDCCH, and wherein the signal indicating the deactivation is received via the PDSCH.
