Abstract
Aspects of a method and system for explicit feedback with a sounding packet for wireless local area networks (WLAN). Aspects of the system may include a beamforming block that may enable generation of a plurality of RF chain signals based on a current steering matrix, where the current steering matrix may be a non-identity matrix. A processor may enable transmission of a request for feedback information via the plurality of RF chain signals. The request may contain medium access control (MAC) layer protocol data unit (PDU) data and channel sounding information, which may be encapsulated in a physical (PHY) layer PDU.
