Claim Text:
1. A method for link adaptation in a wireless communication system, comprising: determining whether a UE operates in a SU-MIMO transmission mode or in a MU-MIMO transmission mode; applying, in responsive to determination that said UE operates in the SU-MIMO transmission mode, a SU-MIMO OUTER LOOP LINK ADAPTATION (OLLA) offset to a signal to interference and noise ratio adjusted with inner loop link adaptation; applying, in responsive to determination that said UE operates in the MU-MIMO transmission mode, a MU-MIMO OLLA offset to a signal to interference and noise ratio adjusted with inner loop link adaptation, wherein said MU-MIMO OLLA offset is based on said SU-MIMO OLLA offset and an extra offset which is indicative of inter-user interference, wherein said SU-MIMO OLLA offset and said extra offset are updated in responsive to receipt of an ACK/NACK message for a packet reported from said UE.
