Abstract

A method for triggering multicell MIMO schemes in a multiple antenna system includes transmitting, at a Mobile Station (MS), a first feedback information for single-cell closed-loop MIMO to a Base Station (BS); requesting, at the BS, Normalized Interference Power (NIP) feedback from the MS based on the first feedback information; feeding, at the MS, the NIP back to the BS; selecting, at the BS, a first NIP threshold and a second NIP threshold based on the NIP fed back from the MS; and requesting, at the MS, one of a first MIMO scheme and a second MIMO scheme by comparing the calculated first and second NIPs with the first NIP threshold and the second NIP threshold.
