Computing system with joint-transmission mechanism and method of operation thereof

A method of operation of a computing system comprising:

• identifying an overall communication content or a portion therein for blind-joint transmission with a second device for utilizing the second device and a third device to send the overall communication content to a first device;
• generating a first encoded set corresponding to the overall communication content or the portion therein for communicating the overall communication content along with a second encoded set for the third device;
• determining with a communication unit a first pre-coding mechanism associated with the first encoded set for communicating the overall communication content with overload transmission mode including a second pre-coding mechanism for the third device;
• and
• communicating a first transmitter signal based on the first encoded set and the first pre-coding mechanism for communicating the first transmitter signal concurrently with a second transmitter signal from the third device.
