  • Decoding channel state information report part two
    Patent number: 12426040
    Abstract: According to some embodiments, a method performed by a network node for decoding a channel state information (CSI) report comprises generating a physical uplink shared channel (PUSCH) scrambling sequence, descrambling a PUSCH using the PUSCH scrambling sequence, decoding a CSI report part one to determine a rank indicator, and determining a location of a CSI report part two. The method further comprises extracting a scrambling sequence from the PUSCH scrambling sequence corresponding to the location of the CSI report part two, generating a CSI part two scrambling sequence based on the PUSCH scrambling sequence and the location of the CSI report part two, and applying the extracted scrambling sequence to the location of the CSI report part two. The method further comprises descrambling the location of the CSI report part two in the PUSCH using the CSI part two scrambling sequence and decoding the CSI part two.
