5G: What is positive/negative Scheduling Request?

Question

Hi,

I'm now studing 5G spec and I cannot find any information about positive/negative Schedulig Request. I guess I understand the basic how Scheduling Request work. But suddenly I encountered these words 'positive' and 'negative' for SR.

Is there any one can explain or show some pointers?

Thanks.

Found this,

*** quote from https://patents.google.com/patent/US**********
 ***
The scheduling request may contain two states: a first one, i.e. a positive scheduling request, where the UE 102 requests to be scheduled and a second one, i.e. a negative scheduling request, where the UE 102 does not request to be scheduled.
