Abstract
A method of operating a communication system includes communicating a sounding signal to a plurality of devices through a first antenna array coupled to a basestation. The method further includes, in response to the sounding signal, communicating a response signal to the basestation from each of the plurality of devices, from the response signal determining device data comprising a device location, a signal strength of the sounding signal and phase information of the sounding signal, grouping the plurality of devices into a first group based on the device data, generating first transmit beamforming weights for the first group to shape the power output of the first beamforming weight vector to communicate a data signal to the first group and broadcasting the data signal to the first group through a wireless signal from the first antenna array using the first transmit beamforming weights and nulls.
