GroupID Concept for Downlink MU-MIMO Transmission

GroupID Concept for Downlink MU-MIMO Transmission. Authors:. Date: 2010-01-18. Background. Non-resolvable LTFs # LTF symbols = max i (# spatial streams for user i) Each user cannot estimate H i Q i reliably unless ||H i Q j ||=0 We cannot guarantee this assumption in general. Advantage

GroupID Concept for Downlink MU-MIMO Transmission

GroupID Concept for Downlink MU-MIMO Transmission. Authors:. Date: 2010-01-18. Background. Non-resolvable LTFs The number of LTFs should be sufficient for each STA to estimate the channel for its own spatial streams Each user cannot estimate H i Q i reliably unless ||H i Q j ||=0
