Abstract: Various solutions with respect to codebook-based uplink transmission in wireless communications are described. A user equipment (UE) receives a first signal from a network node of a wireless network, with the first signal selecting one or more codewords or a codebook from a plurality of different codebooks within a master codebook as allowed precoders at transmission ranks. The UE also receives a second signal from the network node, with the second signal selecting a precoder among the allowed precoders for uplink (UL) transmission. The UE then processes data using the selected precoder and performs an UL transmission of the processed data to the network node.

Abstract: Techniques and examples pertaining to codeword mapping in New Radio (NR) and interleaver design for NR are described. A processor of an apparatus receives, via a transceiver of the apparatus, a Physical Downlink Shared Channel (PDSCH) transmission from a network node of a wireless network. The processor maps one or more codeblocks of a codeword in the PDSCH transmission to a spatial layer group which is a subset of a plurality of spatial layers. The processor also performs receive processing for one or more codeblocks in the PDSCH transmission including by performing de-interleaving on a result from a channel interleaver or from an intra-codeblock interleaver that performs pseudo-random interleaving on systematic bits and parity bits of the one or more codeblocks and channel decoding. The processor transmits, via the transceiver, to the network node a feedback concerning the one or more codeblock and reporting a result of the channel estimation.

Abstract: A method of performing downlink multiuser superposition transmission (MUST) with enhanced channel state information (CSI) feedback is proposed. When a user equipment (UE) reports CQI/SINR feedback for RI=RANK-2, the UE also reports a single beam CQI/SINR feedback for RI=RANK1. As a result, the scheduling base station can calculate the actual SINRs based on different MUST scenarios and thereby determining appropriate modulation and coding scheme (MCS) for the UE. Furthermore, if the granularity of the CQI table cannot reflect the high values of the single beam SINR, then a predefined scaling factor (0

Abstract: A method of determining and adapting a contention window size (CWS) based on channel loading for load-based equipment (LBE) listen before talk (LBT) channel access mechanism is proposed. The historic observations obtained from carrier sensing can reflect the state of channel loading, which is then used to adapt the maximal contention window size. A wireless device collects historical channel loading information including the number of idle slots and the number of busy slots. The wireless device uses the historical information to estimate the total number of active devices M in the wireless network and the channel-loading factor. The wireless device then computes the thresholds using the long-term value of M and then adapts the value of the CWS based on the channel-loading factor and the thresholds.
