Abstract

The invention discloses a communication method and communication device which are used for enabling local side equipment to shake hands with a plurality of CPEs. The communication method is applied toa communication network. The communication network comprises a local side device, User node, and a plurality of CPEs, wherein the central office equipment is connected with the user node through a twisted pair, the user node is connected with the plurality of CPEs, at least one CPE in the plurality of CPEs is in a short-time state, and the CPEs in the short-time state are communicated with the central office equipment in a time division multiplexing mode; The method comprises the steps that a first CPE obtains basic configuration information, the first CPE is one of the multiple CPEs, and thefirst CPE is in a session state; And the first CPE sends a first signal to the local side equipment, and the first CPE indicates whether the first CPE supports the basic configuration information ornot through the phase change of at least one symbol included in the first signal.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] At present, the G.fast project is used to study the fiber to the distribution point (FTTdp) scenario, using copper wires to provide the final high-speed access, and its goal is to provide more than 500Mbps access within 100 meters. input rate. Currently, International Telecommunication Union-Telecommunication Standardization Sector (ITU-T) Q4 is conducting technical research and standard formulation related to G.fast, and the G.fast standard number is G.9701. [0003] The uplink and downlink of G.fast adopt time division duplexing (time division duplexing, TDD). TDD is a half-duplex multiplexing method, that is, both uplink and downlink occupy all subcarriers of the entire frequency band to send information, and the system allocates time slots respectively. In the same time slot, the transceiv...
