Hi,

ENB will give configuration of sub bands in whole bandwidth. UE will give each sub band CQI to ENB. It will calculate SINR in each sub band and calculated CQI on each sub band. So which ever sub band is having good CQI will be utilized efficiently .

How contention will be resolved in case ENB selected preamble?

In the above scenario ENB will not give any CRM message to UE's so how contention will be resolved for UE2?
