Claim Text:
1. A method comprising: receiving, through each receive antenna of a receiving device having m receive antennas, a training signal set transmitted from each antenna of a first transmitting device having n antennas that is a source of interference, wherein the training signal set includes data for each transmit antenna of the n transmit antennas, wherein m and n are each greater than 1, wherein the training signal set is transmitted by the first transmitting device in response to a request by the receiving the device for the transmission of the training signal set, wherein the request that the first transmitting device transmit the training signal set includes an indication of a purpose of the request being for reduction of interference; determining, from the training signal set, a channel estimate for a communication channel between the first transmitting device and the receiving device, wherein the channel estimate includes an m-by-n description of the communication channel based on the data for each transmit antenna of the n transmit antennas; receiving, at the receiving device, a data signal from a second transmitting device; and filtering, based on the determined channel estimate, the data signal to suppress interference injected by the first transmitting device in the data signal transmitted by the second transmitting device.
