Problems solved by technology

In NR, a fixed resource element (RE) mapping order with lower latency is adopted, but the potential gain from time diversity (diversity) may disappear
Furthermore, achieving low processing latency while achieving frequency diversity gain remains a challenge

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. Theprocessor transmits, via the transceiver, to the network node a feedback concerning the one or more codeblock and reporting a result of the channel estimation.
