Ericsson pushes 5G uplink limits with MIMO

Ericsson hit what it claimed was a single-user uplink record using multiple input multiple output (MIMO) technology, taking a step toward overcoming what one executive identified as a key limitation on mobile connectivity.

Uplink MIMO is limited by 3GPP to max 4 layers for PUSCH.

They said UL peak thrp is 315 Mbps.
Should be 4 layers.

No mention if TDD or FDD.
Big difference.

If pattern 4-1 or 8-2, may be 4 UL layers.

The vendor ran the trial on its commercial C-Band radio system, combining single-user MIMO with 256-QAM and its Uplink Booster technology in standalone 5G mode. Using a 100 MHz channel of spectrum from 3.7 GHz to 3.8 GHz, it reached a peak data rate of 315 Mbps on a mobile test device equipped with Qualcomm’s Snapdragon X60 5G platform.

Maybe 7:3.
To have better UL throughput.

Huawei has 2-3 dsuuu for peak UL.
