Criteria for Optimizing SSB Periodicity in 5G NR

[RFSpecialist]

I would really like to see 2 such configurations to understand how is possible not to leak interference.

[Syed_Faraz_Alam]

For that there is a configuration, usually SME.can plan and implement.

@Syed_Faraz_Alam

TDD Pattern 2 is needed to handle specific scenarios where Uplink traffic demand is higher (like AR Gaming, IoT, Stadiums where people uploading more than downloading) or more balanced with Downlink traffic, whereas TDD Pattern 1 is ideal for Downlink-heavy situations.

Do you mean TDD pattern-2 always contains UL slot?

[Syed_Faraz_Alam]

That need SA proper planning.

I can’t share configuration, as it is against loyalty of my work and job.

But to configure a stadium with TDD Pattern 2 and the surrounding network with TDD Pattern 1, ensure:

• Time alignment and frame synchronization across cells.
• Proper use of guard periods and power control.
• Interference coordination (ICIC) between the stadium and nearby cells.
• Use of beamforming to direct signals inside the stadium.

I hope you understand my position.

You just check your vendor and check parameters like:

• Cell ID
• TDD Pattern
• SSB Periodicity
• Guard Period
• Frame Alignment
• Power Control
• Beamforming etc

Thanks!
Point taken!

@RFSpecialist

But how can you run some cells with a TDD configuration (for stadium) and rest of network with other TDD configuration (rest of network)?

Wouldn’t it be strong interference in overlapping area?

In such configuration, we need to ensure that common gp is maintained.

No issue at all then.

Can anyone please explain concept of mgta?

Is it needed for NR SA as well?

If your measurement gap and smtc window are colliding each other, then MGTA is required.

So define the measurement gap in such a way that it cover the smtc window, then MGTA is not required.
