MU-MIMO PROTOCOL EFFICIENCY

摘要

A method for improving multiple-user (MU) multiple-input-multiple-output (MIMO) protocol efficiency includes transmitting an MU frame to multiple devices. The MU frame is beamformed to enable a corresponding one of the devices to receive an intended stream at high power. The MU frame includes an additional sounding-field. Acknowledgement (ACK) responses are received from at least some of the plurality of devices. Each of the ACK responses includes a sounding response frame including a channel feedback.

1. A method for improving multiple-user (MU) multiple-input-multiple-output (MIMO) protocol efficiency, the method comprising:
transmitting an MU frame to a plurality of devices, wherein the MU frame is beamformed to enable a corresponding one of the plurality of devices to receive an intended stream at high power, and the MU frame includes an additional sounding-field; and receiving, from at least some of the plurality of devices, acknowledgement (ACK) responses that each includes a sounding response frame including a channel feedback.
