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.
