Decoding channel state information report part two

A method performed by a network node for decoding a channel state information (CSI) report, the method comprising:

• generating a physical uplink shared channel (PUSCH) scrambling sequence for descrambling a PUSCH without accounting for the existence of a CSI report part two;
• receiving the PUSCH from a wireless device, the PUSCH comprising a CSI report part one and a CSI report part two, wherein the CSI report part one and CSI report part two are encoded independently;
• descrambling the PUSCH using the PUSCH scrambling sequence;
• decoding the CSI report part one from the descrambled PUSCH to determine a rank indicator;
• determining a location of CSI report part two soft bits in the PUSCH based on the rank indicator;
• extracting a scrambling sequence from the PUSCH scrambling sequence corresponding to the location of the CSI report part two in the PUSCH;
• generating a CSI part two scrambling sequence based on the PUSCH scrambling sequence and the location of the CSI report part two in the PUSCH with correct x and y locations;
• applying the extracted scrambling sequence to the location of the CSI report part two soft bits in the PUSCH to undo the incorrect scrambling;
• descrambling the location of the CSI report part two soft bits in the PUSCH using the CSI part two scrambling sequence;
• and
• decoding the CSI part two.
