Generation Node-B (GNB), User Equipment (UE) and Methods for Interleaving in Multiple-Input Multiple-Output (MIMO) Arrangements

Abstract

Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may map data symbols to resource elements (REs) of virtual resource blocks (VRBs). The gNB may interleave the data symbols, on a per-VRB basis, to spatial layers of a multi-layer multiple-input multiple-output (MIMO) transmission. The data symbols may be interleaved based on different interleave patterns of VRB indexes for the spatial layers. The gNB may map the interleaved data symbols of the spatial layers to REs of physical resource blocks (PRBs) for orthogonal frequency division multiplexing (OFDM) transmission.

1 . An apparatus of a Generation Node-B (gNB), the apparatus comprising:
 memory; and processing circuitry, configured to:
 map data symbols to resource elements (REs) of virtual resource blocks (VRBs); 
 interleave the data symbols, on a per-VRB basis, to spatial layers of a multi-layer multiple-input multiple-output (MIMO) transmission, 
 wherein the data symbols are interleaved based on different interleave patterns of VRB indexes for the spatial layers; and 
 map the interleaved data symbols of the spatial layers to REs of physical resource blocks (PRBs) for orthogonal frequency division multiplexing (OFDM) transmission, 
 wherein the memory is configured to store the data symbols.
