Abstract:
1. A method, in a radio transceiver that supports two or more Multiple-Input Multiple-Output (MIMO) transmission and reception modes, the method comprising: evaluating channel conditions between the radio transceiver and a remote wireless device; comparing a throughput demand for the remote wireless device to a forward link capacity or reverse link capacity, or both, wherein the forward link capacity or reverse link capacity is calculated to at least take into account an anticipated modulation and coding scheme (MCS) that is based on channel quality; based on the channel conditions and the throughput demand, changing a forward link transmission mode or a reverse link transmission mode, or both, from a first multi-stream mode to a second multi-stream mode, the second multi-stream mode having fewer streams than the first multi-stream mode, despite that channel conditions for the corresponding link support the first multi-stream mode.
