According to a report by Ericsson, Rel-17 MIMO enhancements address four areas: Beam management; multiple transmission and reception points (mTRP) for ultra-reliable, low-latency communication (URLLC); mTRP for enhanced mobile broadband (eMBB); and TDD and FDD reciprocity.
“The multi-beam enhancements are intended to improve performance at high mobility by streamlining signaling and to optimize performance for user equipment (UE) with multiple antenna panels. The mTRP enhancements increase robustness for the physical downlink control channel (PDCCH), physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH),” Ericsson said. “They also enable richer channel state information (CSI) feedback for non-coherent joint transmission (NC-JT) and optimize performance for high-speed-train (HST) communication scenarios.
