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.
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.
To have better UL throughput.
Huawei has 2-3 dsuuu for peak UL.
