- In this episode I explain how 5G UL power control works in different scenarios. How it is different from previous technologies and what kind of power adjustments could be done in DL direction.
🌋Time codes:
0:20 - Main goals of Power Control
1:00 - Open Loop power control
3:50 - Closed Loop power control
6:02 - DL power control (CSI-RS, PSS, PDCCH power boost)
10:27 - UL power control (based on TPC commands or SINR)
14:24 - Conventional and Fractional power control
17:17 - Beam-specific power control
18:15 - EN-DC and UL CA power sharing

Hi Gleb, I had some questions about the UL power Control.
1. You said PRACH use Open Loop but PUSCH & PUCCH use Closed Loop, right? And you mentioned the conventional & fractional power control used for PUSCH & PUCCH (fractional only). But do the conventional & fractional power control belongs to Open Loop?
2. Do you know which kind of power control used for the real network? If we know that the uplink power in the real network will increase when the DL signal is not good, can I said that it should use the open loop power control in PUSCH?
3. If I disable the TPC control setting in the NW simulator, shall it represent that I am using open loop for PUSCH?
Hello!
1) Conventional & fractional power control belongs to closed loop power control!
2) PRACH - open loop / other UL channels works in closed loop power control
3) Don't know exactly...
@@5G_Understanding I got it. Thanks.~
