Question 1:

How to Generate LTE UL Resource Grid for One frame (10 Subframe) without using a loop? How to configure "lteULResourceGrid(ue)" for the same?

One option is using for loop. Generate Grid for one subframe at a time then run the for loop to generate 10 subframe Grid.

But I am looking for something that "lteRMCULTool" does internally.

Question 2:

How "lteRMCULTool" work internally.

Hello Niki Sonowal,

Currently, the lteULResourceGrid function returns a resource array for one subframe only for the corresponding UE-specific settings. I have brought this issue to the notice of the concerned people, and it might be considered for a future release. The lteRMCULTool function also creates resource grid for each subframe (from the total calculated absolute sub frame number and total sub frame) and concatenates to form a complete frame. To look through the lteRMCULTool function run the following code in the MATLAB Command Window,

Also, This behaviour is by design. lteULResourceGrid creates an empty grid which needs to be populated. The indices and symbols generated (physical channels and signals) target one subframe. Hence you need to populate them one by one.

To know how to map signals into the resource grid, you can look at the example in this link. LTE Downlink Channel Estimation and Equalization
