Thanks Charles,

I am not too specific about the device type. But specific to Bit-rate Co Processor (BCP). So it can be any device that has BCP.

Please let me know the details for the question asked. 

Harq combining method (chase combining or incremental redundancy) and what is the expected gain with combining enabled? Is there any configurations that can be altered to get the required gain..?

Thanks & regards,

Ashok

Hi Ashok,

 As much as I'd like to help, we just don't have any experts with knowledge to answer your technical questions. This is the reason we refer customers to the 3rd party support. 

Hi Charles,

The third party resources provided are for video applications. Can you direct us to resources pertaining to LTE applications..? 

Also I posted this query after searching through all the possible posts on the related topic in all earlier e2e posts. I have not got my answers.

Thanks & Regards,

Ashok

Hello Ashok 

Charles forwarded me this thread. Unfortunately would need to re-iterate what he already posted - these wireless accelerators like BCP etc for LTE applications was a very specific set of hardware and software , that is no longer supported by TI for almost 6+ years now. Most people associated with this IP and software are no longer with TI. 

You are correct that in this case the listed 3P are not likely the right ones for these modules. 

You can try to reach out to 3Ps like Commagility and Azcom as listed on this E2E post

The product you are working is an older generation to K2K , K2L, but perhaps they may have some guidance or support to offer in this domain.

No additional guidance/support is possible from TI side on your query.

We regret the challenge it presents for your development

Thanks Mukul,

Actually I am working on 6638K2K which was not available in the device list, hence I selected 6670 which was available in the Device list and also supports BCP.

And I am not asking any support in this aspect, I am just checking if we have any information/documentation/design in place when this BCP was introduced, which can give more info regarding the harq combining method used and any bench marking results on the co processor.

Thanks & Regards,

Ashok

Hi Ashok

No additional information beyond what you see in the public domain.
