Abstract:
The present invention proposes methods for facilitating and improving the performance of MU-MIMO transmission in wireless communication systems. Each user within a MU group inserts an inter-user interference indication field in its acknowledgement packet. The inter-user interference indication field includes signal-to-interference-noise-ratio (SINR) and interference source information. The MU-MIMO transmitter extracts inter-user interference indication feedback and improves subsequent MU-MIMO transmission. Feedback of the inter-user interference information such as SINR and interference source allows efficient link adaptation, smarter user selection, channel re-sounding selection, and fine-tuning of precoding matrix.
