Title:
METHOD AND DEVICE FOR AVOIDING COEXISTENCE INTERFERENCE BETWEEN HETEROGENEOUS TECHNIQUES WITHIN BUNDLE CABLE
Document Type and Number:
WIPO Patent Application WO/2018/012819
Kind Code:
A1
Abstract:
A method by which a coexistence device transmits, to a terminal, data signals outputted from different line concentrators in a home network transmission line comprises the steps of: receiving a first data signal from a first line concentrator and receiving a second data signal from a second line concentrator; extracting a transmission period of the first data signal so as to estimate a frequency of a first synchronization signal, which is a synchronization signal of the first data signal, and extracting a transmission period of the second data signal so as to estimate a frequency of a second synchronization signal, which is a synchronization signal of the second data signal; generating a coexistence synchronization signal by using the frequency of the first synchronization signal and the frequency of the second synchronization signal; and respectively transmitting the first data signal and the second data signal to a first terminal and a second terminal in correspondence to the coexistence synchronization signal.
