Query regarding Pucch format 2a/2b detection using BCP COR module

Aditya Khanna

i am trying to implement a LTE PUCCH format 2a/2b detector. In the BCP document it says that the data has to be input twice (for Format 2a) and Four times (for format 2b) depending on ACK/NACK posibilities.

i am not able to understand whether i have to input the same data (received over all symbols) again or i need to change the data corresponding to symbol 5 depending on ack/nack possibilities.

Also does the BCP give me the final output for ACK/NACK bit, or that should be part of preprocessing?

Thanks in advance.

regards,

Hi raja,

we are using TMDSEVM6670L and BIOS-MCSDK 02_01_02_06 for development.

Hi Aditya,

The attached document provides an overview of PUCCH processing by the BCP. The input data for symbol 5 needs to be changed according to the ACK/NACK possibilities before sending to the BCP. Please refer to item-4 in the attached document for more details on this.
