Title: COMMUNICATION METHOD, CABLE MODEM TERMINAL SYSTEM, AND CABLE MODEM
Abstract:
The invention provides a communication method, a cable modem terminal system (CMTS), and a cable modem (CM). The communication method comprises: a CMTS sends, in a first time interval, and using an effective carrier in the first frequency band, a reference signal, wherein during the first time interval, no CM connected to the CMTS transmits a signal in the first frequency band; the CMTS performs, according to an interference signal received by the CMTS in the first time interval channel interference estimation for a channel occupying the first frequency band and employed by the CMTS to receive signals, wherein the interference signal is obtained by propagating the reference signal through the channel; and the CMTS eliminates, according to a result of the channel interference estimation, interference of a first signal received by the CMTS on a second signal received by the CMTS, wherein the first signal is transmitted by the CMTS and using a carrier in the first frequency band, and the second signal is transmitted by a first CM in all CMs and using the carrier in the first frequency band. When the CMTS operates in CCFD, the technical solution provided in the invention can reduce complexity of self-interference cancellation.
