Disclosed are a TM9-based carrier aggregation (CA) method and device, the method comprising: a network side device determines a component carrier (CC) currently activated in a CA system; if a CC configured with TM9 exists in the currently activated CCs, the network side device determines a CC<b/>transmission mode (TM) for the CC configured with TM9; the network side device transmits data to a UE according to the TM. An embodiment of the present invention enables a CA cell to support CA of 8 downlink (DL) ports for TD-LTE-A cell using TM9, thus increasing user rate and improving user experience. The method increases checkpoints such as maximum supporting data streams and UE capability, thus increasing user throughput. |
