| 摘要 |
Embodiments of the present invention relate to a CA-based signal transmission method, apparatus and device. The method comprises: determining whether a secondary carrier is in a state requiring detection of a receiving side device; and if the secondary carrier is in the state requiring detection of the receiving side device, generating an indication signal, and sending the indication signal to the receiving side device by carrying the indication signal in a subframe of a primary carrier, so that the receiving side device detects, according to the indication signal, whether a signal sent by a sending side device exists on the secondary carrier. The CA-based signal transmission method, apparatus and device provided in the embodiments of the present invention reduce the complexity and power consumption of a communication system. |
