  This paper introduces a novel physical-layer method labelled as Multi-Modal
Concurrent Transmission (MMCT) for efficient transmission of multiple data
streams with different reliability-latency performance requirements. The MMCT
arranges data from multiple streams within a same physical-layer transport
block wherein stream-specific modulation and coding scheme (MCS) selection is
combined with joint mapping of modulated codewords to Multiple-Input
Multiple-Output spatial layers and frequency resources. Mapping to
spatial-frequency resources with higher Signal-to-Noise Ratios (SNRs) provides
the required performance boost for the more demanding streams. In tactile
internet applications, wherein haptic feedback/actuation and audio-video
streams flow in parallel, the method provides significant SNR and spectral
efficiency enhancements compared to conventional 3GPP New Radio (NR)
transmission methods.
