Codeword Mapping In NR And Interleaver Design For NR

摘要

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.
