Overview about 5G PDSCH Multiplexing with PDSCH DMRS
💡 What is it?
PDSCH Multiplexing simply means leveraging the free resources within the PDSCH DMRS Symbol for optimal PDSCH utilization.
📈Expected Gain:
Experience an increase in the maximum user throughput for users in good radio conditions.
🚫 Expected Drawbacks:
There's always a tradeoff. Be mindful of the impact on EDGE Users due to the DRMS power boosting. "The free resources power was being used for other RS, which was increasing DMRS power by around 2~3dB"
🚧 Important Note:
PDSCH Multiplexing is a no-go for Rank 3, Rank 4, and MU-MIMO Users, as all 4 ports will be utilized for DMRS.
