Radio Frequency (RF) & Wireless Design

This is something you have to figure out locally since it could be thousands of reasons why its failing.

Talk to your instructor !

Steven I understand you very well .. but that's why I posted the question/problem because I don't know even which approaches to take.

Since you said thousands of reasons .. may you tell me in general why my EnodeB isn't getting SR from the uE - from the uplink transmitter- .. implicitly my enodeB is rejecting all SR'S and not responding to the UE .

May you please assign here which reasons could be incharged of this problem . I dont know what attempts to take / to check that's why I posted here . Although I have no instructor - otherwise I wasnt asking here. Appreciate for your help

my problem is that;

my UE transmits SR to EnodeB but I have SR fail it means the EnodeB not collecting / recognizing / detecting SR requests from the uplint transmission , what attempts should I do /implement in order to solve that problem?

in other words it means that the UE isn't receiving the Up link grant from EnodeB although the UE transmits the SR to EnodeB.

thanks alot

Jimmy ;

I don't know if this is a hardware (signal), firmware (fgpa, bios, dsp, cpu, mcu), or software (C, pyton, java, etc) problem.

So first you need to fault isolate to one of the domains.

Then you need to fault isolate within the domain.

This is YOUR problem not our responsibility, so you need to have as much exact clarity before any problem can be resolved.

I don't see any clarity in what you are asking, so its a guessing match at this point.

Go back to the basics and see what does work and trouble shoot to find out when it breaks with the minimal configurations.

If you didn't design this, then get help from those who did.
