each ue has 3000 subfrequencies to work with, maybe 1500 are usable for data, 1 usable for synchronization
ue will not use all of them together, for max bandwidth
it will use a subset at a time, lower bandwidth
the allocation of the specific frequency set is indicated by eNb
so at a time multiple UE's will talk with eNb under different subsets of 3000 frequencies
if an eNb is overutilised another eNb in the same area can taken over more connections than 3000
the spectrum will be shared between different eNbs in the area
each spectrum band is split into 3000
Transport Block - mac unit
the centre frequency 1500 is used for special purpose
