Abstract: Training data for a first training session is generated to include a first data unit, the first data unit having a field that specifies a first number of beamforming training data units that can be communicated during a second training session to occur after the first training session. The training data including the first data unit is transmitted to a second device during the first training session. A second data unit received from the second device is processed to determine whether a request for the second device to participate in the second training session was accepted by the second device based on a first field of the second data unit. In response to determining that the request to participate in the second training session was accepted by the second device, the first number of beamforming training data units are transmitted during the second training session.

Abstract: Systems and methods are provided for decoding signal vectors in multiple-input multiple-output (MIMO) systems, where the receiver has received one or more signal vectors based on the same transmitted vector. The receiver linearizes each received signal vector using one or more zero-forcing, MMSE, or other suitable linear equalizers. The components of the equalized signal vectors may be combined using maximum-ratio combining to form the components of a combined equalized signal vector. The components of the combined equalized signal vector may then be decoded individually using a linear decoder.
