Abstract:
1. A method, comprising: transmitting a sounding packet to one or more wireless communication devices to determine characteristics of spatial wireless channels, wherein the sounding packet is based on a spatial mapping matrix; receiving, in response to the sounding packet, one or more feedback packets from the one or more wireless communication devices, wherein the one or more feedback packets are indicative of one or more feedback matrices, the one or more feedback matrices being derived from wireless channel estimations that are based on received versions of the sounding packet; generating spatially steered data packets based on multiple data streams and one or more steering matrices, the one or more steering matrices being based on the spatial mapping matrix and the one or more feedback matrices; and transmitting a frame that includes the spatially steered data packets to the one or more wireless communications devices, wherein the spatially steered data packets concurrently provide the data streams respectively within the frame to the one or more wireless communication devices via different spatial wireless channels.
