lte RB Allocation Types (Selection)

RbgAlloc Strategy RBG Resource Allocation Strategy Meaning: Indicates the resource block group (RBG) allocation strategy, which is used to adjust spectral efficiency and throughput of the cell. Consider the situation where the number of required RBGs is greater than N but less than N+1 (where N > 1). If this parameter is set to ROUND_DOWN(Round Down), RBs of N RBGs are allocated to UEs in the current transmission time interval (TTI) and the remaining RBs are allocated to UEs in the next TTI. If this parameter is set to ROUND_UP(Round Up), RBs of N+1 RBGs are allocated to UEs in the current TTI.

If this parameter is set to ROUND_UP(Round Up), a few allocated RBs are not utilized, spectral efficiency is low, but cell throughput is relatively high.

RBG Resource Allocation Strategy

Meaning: Indicates the resource block group (RBG) allocation strategy, which is used to adjust spectral efficiency and throughput of the cell.
