Patent ID: 8855228

Claim:
A method, comprising: determining, at a first transceiver device, a partial dimensional description of a reverse multiple input, multiple output (MIMO) channel based on a reception of a first packet received from a second transceiver device via the reverse MIMO channel, wherein the first packet includes training information of spatial dimensions used for the transmission of the first packet but does not include training information for all available spatial dimensions of the reverse MIMO channel, wherein the reverse MIMO channel corresponds to a signal direction from the second transceiver device to the first transceiver device; developing, at the first transceiver device, a correction matrix from (i) the partial dimensional description of the reverse MIMO channel and (ii) a description of a forward MIMO channel, wherein the forward MIMO channel corresponds to a signal direction from the first transceiver device to the second transceiver device; and using, at the first transceiver device, the correction matrix to process signals to be transmitted via the forward MIMO channel.
