Can SRS-usage: antenna switching in 5G improve downlink throughput in TDD case?

Hi Experts.

If yes, then how?

SRS beam weights are more accurate than PMI beam weights.

This way DL throughput can be improved compared to PMI.

PMI beam weight- UE which send PMI after estimating CSI-RS.

How is the SRS beam weight estimation?

Based on SRSs sent in Uplink.

Do you mean gNB estimate beam weight?

How is the flow?

Thank you!

One point which I had mentioned earlier.

UE gets SRS configuration with “usage- antennaSwitching”.

How it helps in better throughput?

SRSantennaswitching does not play any role in beam weight calculation.

Thanks.
