Abstract:
1. A method for transmission mode adaptation performed at a receiver of a wireless network, the method comprising: measuring a wireless channel based on a signal transmitted from a transmitter; determining one or more signal-to-interference-plus-noise ratios (SINRs) for each transmission mode of a plurality of transmission modes based on the wireless channel measurement; determining an aggregate throughput of each transmission mode based on the one or more SINRs of that transmission mode; determining whether there are multiple candidate transmission modes for a transmission over the wireless channel, each candidate transmission mode having a same determined highest aggregate throughput among the plurality of transmission modes; and selecting a transmission mode for use by the transmitter from among the candidate transmission modes based on the one or more SINRs of the candidate transmission modes when it is determined that there are multiple candidate transmission modes, wherein each transmission mode specifies one or more parameters for a transmission from the transmitter to the receiver of one or more layers via one or more antennas at the transmitter, and specifies a mapping of codewords to layers.
