Have any idea about Resource Allocation Modeling in LTE? I just need in brief.

Question

Actually there are three resource allocation types being used to allocate resources to UE(s) in downlink and uplink. For downlink all three (Type 0, 1 and 2) used but for uplink only resource allocation type 2 is being used.

Answer 1

The scheduler is in charge of generating specific structures called as Data Control Indication (DCI). Which transmits by ENodeB to the connected UE’s.

To inform the users about resource allocation in the downlink direction the scheduler has to fill some specific fields of the DCI structure with all the information.

For example: the Modulation and Coding Scheme (MCS), the MAC Transport Block (TB) size, and the allocation bitmap, which identifies which RB's will contain the data transmitted by the ENodeB to each user.
