Methods and systems for providing beamforming feedback in a communication channel are disclosed. A data packet is received at a beamformee circuitry of the first communication device configured to generate beam steering data for use by a transmitter of a second communication device. Each of a plurality of tones of the received data packet is processed to generate a compressed steering matrix corresponding to the communication channel. In parallel to the processing of the received plurality of tones, an immediate feedback packet comprising a plurality of data symbols is constructed, where the data symbols include the generated compressed steering matrix. At least a first data symbol of the immediate feedback packet is transmitted prior to completing the processing of all the plurality of tones of the received data packet.

Method for efficient beamformee implementation for Wi-Fi

A method for deinterleaving a plurality of resource units (RUs) where each RU includes data and parameters. The method includes assigning each RU into one of a first deinterleaver and a second deinterleaver and storing the parameters of each respective RU to a respective buffer in an order. The method also includes processing the data of the respective RU in the one of the first deinterleaver and the second deinterleaver and upon completion of the processing of the data of a respective RU, outputting the data of the respective RU from the one of the first deinterleaver and the second deinterleaver into which the respective RU was assigned, outputting the parameters of the respective RU corresponding to one of the first deinterleaver and the second deinterleaver into which the respective RU was assigned, and aligning the parameters of the respective RU with the data of the respective RU based on the order of storage of the parameters in the respective buffer.
