Patent ID: 7525985

Claim:
An apparatus for collision resolution in a home networking system using carrier sense signals, the apparatus comprising: a received frame state extraction unit, which extracts a current state CurST of a frame including carrier sense signals received by a station that is connected to a network, a data transmission priority RxPRI of the received frame, and a reference time signal do_FBOS for determining a final state of the carrier sense signals of the received frame, wherein the reference time signal do_FBOS is assigned to be within a last section in a back-off slot section of the received frame to determine the final state of the carrier sense signals, the back-off slot section to be followed by a priority slot section of the received frame for transmitting data; a maximum back-off level (MBL) calculation unit, which calculates MBL values MBL_reg based on the current state CurST, the priority RxPRI, and the reference time signal do_FBOS; MBL registers, which store the MBL values MBL_reg; a back-off level (BL) calculation unit, which calculates BL values BL_reg based on the current state CurST, the priority RxPRI, the reference time signal do_FBOS, and the MBL values MBL_reg; and BL registers, which store the BL values BL_reg.
