12 Feb 2010 07:34 PM Alert This question is being submitted by Venkatesh Sampath on behalf of the Canadian Evaluation Group. The Canadian Evaluation Group or CEG has evaluated the IMT-ADV/4 response from IEEE and has the following question for clarification: In IMT-ADV/4, we note that Table 6-3: “L1 / L2 Overhead estimation” provides results for DL 2x2 and DL 4x2 antennas… could you please provide similar information for a DL 4x4 antenna system ?
