Abstract:
1. A method for triggering multicell Multiple Input Multiple Output (MIMO) schemes in a multiple antenna system, the method comprising: receiving, at a Base Station (BS), a first feedback information for single-cell closed-loop MIMO from a Mobile Station (MS); requesting, at the BS, Normalized Interference Power (NIP) feedback from the MS based on the first feedback information; receiving, at the BS, the NIP feedback from the MS; selecting, at the BS, a first NIP threshold and a second NIP threshold based on the NIP feedback from the MS; and receiving, at the BS, a request from the MS of one of a first MIMO scheme and a second MIMO scheme, the request based at least partly upon a comparison of the calculated first and second NIPs with the first NIP threshold and the second NIP threshold.
