Abstract

A first access point comprises circuitry configured to perform a sounding procedure with one or more first stations associated with the first access point and configured to communicate with the first access point over a respective channel to determine resource unit allocation and beamforming configuration for use in subsequent communication with respective first stations, and to transmit a training data unit containing signaling information related to the determined resource unit allocation and related to the determined beamforming configuration, wherein the training data unit is transmitted with a beamforming configuration derived from the determined resource unit allocation and the determined beamforming configuration.
