How User EnodeB decide the size of information that User Equipment has to send to it in LTE (4g) wireless?

Hello guys,
How it is decided that how many resource elements are utilized for control or to carry data between EnodeB and UE? I mean lets assume UE have 100000000000 packets of data to send to EnodeB , how does the UE know how much data(how many packets0 it will send to EnodeB? for instance every 100packets or X packets ...or whatever ... how does the UE knows how much data from what it has to send to EnodeB ?

How does the procedure of determining the size of frame to be sent to/from EnodeB is done? which parameters determine the size of the data that need to be sent from UE to/from EnodeB?

Assume there's more than UE connected to EnodeB at the same Time.

Appreciated for any help.

It likely has to do with the QoS and the GBR for the UE that are established as part of the initialization of the connection :
