Abstract: The present disclosure comprises improvements to Physical Downlink Shared Channel (PDSCH) throughput by switching between Maximum Ratio Combining (MRC) and Interference Rejection Combining (IRC) demodulation based on interference levels in a Physical Uplink Control Channel (PUCCH) transmission received from a wireless communication device. The base station can demodulate the PUCCH transmission using MRC if interference level is below a predefined interference level and IRC if it is above the predefined interference level. The base station can then decode the PUCCH transmission using either polar decoding or Reed-Muller decoding based on the number of information bits in the PUCCH transmission and determine an interference metric associated with the PUCCH transmission. Based on one or more of a Hybrid Automatic Repeat Request (HARQ) acknowledgment (ACK) or negative acknowledgement (NACK), DTX detection, and the interference metric, the base station can perform one of a variety of functions.

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.
