摘要:
The present invention provides a communication method, a CMTS, and a CM. The communication method includes: sending, by a CMTS, a reference signal within a first time period by using a valid subcarrier in a first spectrum, where the first time period is a time period within which none of CMs connected to the CMTS sends a signal in the first spectrum; performing, by the CMTS based on an interfering signal received by the CMTS within the first time period, channel interference estimation on a channel that is used during signal reception of the CMTS and that occupies the first spectrum, where the interfering signal is a signal obtained after the reference signal passes through the channel; and canceling, by the CMTS based on a result of the channel interference estimation, interference from a first signal received by the CMTS to a second signal received by the CMTS, where the first signal is a signal sent by the CMTS by using a subcarrier in the first spectrum, and the second signal is a signal sent by a first CM in all the CMs by using a subcarrier in the first spectrum. Technical solutions provided in the present invention can reduce self-interference cancellation complexity of a CMTS during CCFD.

The embodiments of the present invention provide a physical-layer-based handover method. The method includes: generating handover signaling, where the handover signaling carries a signaling type identifier and a destination identifier that are used for handover, and the handover signaling is an HS-SCCH order or specific HS-SCCH signaling; and sending the handover signaling to a physical layer of a mobile terminal, so that the mobile terminal executes handover according to the handover signaling to be handed over to a small cell indicated by the destination identifier. A handover method based on a network side physical layer and a mobile terminal physical layer is provided, and even if cell IDs of a macro cell and a small cell or those of small cells are the same, handover of the mobile terminal can be implemented.
