Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of wireless communication, comprising: transmitting a MIMO uplink utilizing a first stream and a second stream in a dual stream mode; receiving HARQ feedback indicating a decoding failure of a packet on the second stream and a decoding success of a packet on the first stream; receiving a command to switch from the dual stream mode to a single stream mode; determining to only transmit the first stream in response to the command; allocat…
