Resource Element (RE) : The smallest unit made up of 1 symbol x 1 sub-carrier. Resource Element Group (REG) : a group of 4 consecutive resource elements.
Can some can explain the difference between Resource Element Groups (REG) and PHICH Groups?
I'm still confused with the statement that says, "A total of 8 orthogonal sequences have been defined, so each PHICH group can carry up to 8 PHICHs."
How the capacity depends upon these resource blocks and how large it is ?
I saw this IE in sib1. I want to know much more about it. What is the use of this and either it can be used in femto cell or macrocell or both.
