Method and apparatus for performing carrier management in carrier aggregation system

摘要

A carrier aggregation system, includes transmitting a first signaling to configure one additional carrier to a user equipment (UE) at which the additional carriers are deactivated, to configure a timer to each additional carrier for the UE by which the carrier is deactivated after the corresponding timer expiry; transmitting a second signaling that carries an activation indication to the UE to activate one deactivated additional carrier in the configured carriers for the UE; activating at least one deactivated additional carrier, starting the timer, controlling the UE to start Physical Downlink Control Channel (PDCCH) monitoring and Physical Downlink Shared Channel (PDSCH) receiving on the activated additional carrier; transmitting PDCCH on the activated additional carrier for the UE, by which the corresponding timer being restarted; deactivating the activated carrier after the corresponding timer expiry, controlling the UE to stop the PDCCH monitoring and the PDSCH receiving on the deactivated additional carrier.

1. A method performed by a base station for carrier configuration and activation in a carrier aggregation system, comprising:
transmitting a first signaling to configure at least one additional carrier to a user equipment (UE) at which the additional carriers are deactivated, and to configure a timer to each additional carrier for the UE by which the carrier is deactivated after the corresponding timer expiry; transmitting a second signaling that carries an activation indication to the UE to indicate the UE to activate at least one deactivated additional carrier in the configured carriers for the UE; activating the at least one deactivated additional carrier, starting the corresponding timer and controlling the UE to start Physical Downlink Control Channel (PDCCH) monitoring and Physical Downlink Shared Channel (PDSCH) receiving on the activated additional carrier; transmitting PDCCH on the activated additional carrier for the UE, by which the corresponding timer being restarted; and deactivating the activated additional carrier after the corresponding timer expiry and controlling the UE to stop the PDCCH monitoring and the PDSCH receiving on the deactivated additional carrier.
