BCP for PUSCH Transmission with UCI and channel interleaver

Ashok H.S.

Hi all..

Has any one used the BCP of 6630K2L for the bit rate processing of PUSCH channel of LTE uplink transmitter with UCI data and channel interleaver..? If yes can you guide me how to configure the MOD module of BCP for the same..?

Regards,

From my understanding, there is no major update on BCP between keystone I and II. Please refer below similar threads on BCP,

Thanks Raja for the reply...but I have gone through most of the posts in the forum which talk only about BCP in PUSCH demodulation that is in eNBRx. But my question is about using the BCP in PUSCH transmission that is UeTx.

Hi Ashok,

I have assigned this post to BCP experts. They will get back to you. Thank you for your patience.

Hi Ashok,

I'm looking into this question and shall get back to you soon. I understand that you want to use BCP for PUSCH TX but is this for interference cancellation processing (SIC or PIC) in PUSCH uplink as given in section 2.3.4 of the BCP user guide?

Hi Nitin,

Thanks for the mail. Yes I'm looking at the PUSCH Tx and not the SIC PIC. If we see the PDSCH Tx and PUSCH Tx all parts in the bit rate processing is same from the CRC to modulation except for the channel interleaver between the rate matching unit and scrambler & modulator unit.

And I see that the modulator if used in soft modulation mode, does some interleaving with some dummy data for ACK NACK and RI and CQI bits...so was curious to know if we can use this feature some how to use the BCP without break from CRC to modulated symbols for PUSCH also...

Regards,

Ashok
