DOCSIS MAC-PHY downstream convergence layer

Techniques are provided herein for transmitting data across multiple carriers using Motion Picture Experts Group (MPEG) Transport Stream (TS) packet multiplexing. At a processing device coupled to at least one subscriber device data associated with the at least one subscriber device are received. The data are encapsulated into MPEG-TS packets, where the MPEG-TS packet headers identify a single data channel for the at least one subscriber device. The MPEG-TS packets are multiplexed across a plurality of radio-frequency (RF) carriers for transmission, and the MPEG-TS packets are transmitted using the plurality of RF carriers. Each of the plurality of RF carriers have the same RF modulation, use the same symbol rate, and are driven by the same clock such that the carriers are synchronous. Techniques are also provided recover the data at the subscriber device.
