Hi Ragnar,

 

Thank you again for your detail review. For the variable “config”, it was my mistake while I redrew the state diagram. I also agree with you that “_down” should be “_done”. I will update another version for the correction.

 

Regards,

Frank

Hi Ching-Yen, Frank, and Wei,

 

I have a question regarding your presentation:

            https://www.ieee802.org/3/dm/public/1125/Lee_etal_3dm_01a_1125.pdf

 

In the “Updated TDD PHY Control State Diagram” on slide 4, the transition criteria out of the COUNTDOWN0 and COUNTDOWN1 states are given as

config = (MASTER * loc_countdown0_down) + (SLAVE * rem_countdown0_down)

 

This text does not appear to be consistent with the conventional use of the “config” variable, including the transition criteria out of the SILENT state. I assume that the criteria are meant to be

((config=MASTER) * loc_countdown0_down) + ((config=SLAVE) * rem_countdown0_down)

 

Can you please confirm that my understanding is correct?

 

I also wonder if “loc_countdown0_down” should be named “loc_countdown0_done”, for consistency with other variables like “minwait_timer_done”.

 

Ragnar
