Patent ID: 8149861

Claim:
A method for transmitting data in a coax network to implement uplink data and downlink data transmission on a same physical transmission channel between an access point and each coaxial terminal in a coax distribution network, comprising: dividing an entire time duration of a physical transmission channel for transmitting information into time slices, and organizing all the time slices into two time slots, one for uplink data transmission and the other one for downlink data transmission; obtaining the length of a period that each coaxial terminal maintains a synchronized clock, and dividing the time slot for uplink data transmission into a plurality of uplink sub-slots according to the length; transmitting, by different coaxial terminals, uplink data to the access point at different uplink sub-slots; and transmitting, by the access point, downlink data to each coaxial terminal at the time slot for downlink data transmission; wherein dividing the time slot for uplink data transmission into a plurality of uplink sub-slots according to the length comprises, obtaining the length of each uplink data frame to be transmitted by each coaxial terminal, and dividing the time slot for uplink data transmission into a plurality of uplink-sub-slots according to the length of the period that each coaxial terminal maintains the synchronized clock and the length of each uplink data frame to be transmitted by each coaxial terminal.
