Title:
SYSTEM AND METHOD FOR UPLINK MULTIPLE INPUT MULTIPLE OUTPUT TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2012/064784
Kind Code:
A3
Abstract:
Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In some particular aspects, scheduling of the uplink MIMO transmissions may make a determination between single stream, rank=1 transmissions and dual stream, rank=2 transmissions based on various factors. Further, when switching between single and dual stream transmissions in the presence of HARQ retransmissions of failed packets, the scheduling function may determine to transmit the HARQ retransmissions on a single stream transmission or to transmit the HARQ retransmissions on one stream while transmitting new packets on the other stream.
