LTE UL Pre Allocation question


#1

Hello all, I would like ask for your opinion.

I have a LTE Huawei Site where a latency test was performed in the field and this result is very high, the Site is with a very high number of users, and I found that when we have a high traffic on the Site the UL PRE ALLOCATION stops working and this causes high latency.

My question is, which is the UL PRE ALLOCATION?

The high traffic might be an UL interference in the first place. Because prescheduling causes high interference and waste of channel resources. If the load generally is high try to deactivate the preschedling thing. Preallocation increases with low number of users. So maybe better to deactivate preschedling to improve the accessibility latency.
This is theoretically
