Techniques enabling fast transmit rates and antenna adaptation for wireless networks based on explicit feedback

A method, comprising:

• adapting antenna use configurations used in wireless transmissions between wireless devices based on explicit feedback by at least one of said wireless devices;
• including in said explicit feedback information indicating the combination of antennas to use in communicating between said wireless devices;
• transmitting sounding packets by at least one other wireless device to said least one wireless device and wherein said at least one wireless device is capable of responding to said at least one other wireless device with information indicating the combination of antennas to use in communicating between said wireless devices;
• and
• indicating the combination of antennas to use for communicating between said wireless devices by said at least one wireless device transmitting feedback to said at least one other wireless device using a Responder Aggregation Control with additional information bits containing said information indicating the combination of antennas to use;
• wherein supporting cyclic delay diversity (CDD) by setting more than 1 antenna selection bit when an modulation coding scheme (MCS) rate <=54 Mbps is returned as feedback.

A system, comprising:

• at least one wireless station in a wireless communication network;
• and
• a base station capable of transmitting sounding packets to said at least one wireless station in said wireless network, wherein said at least one wireless station is capable of responding to said base station with information indicating the combination of antennas to use in communicating between said base station and said at least one wireless station;
• wherein said information indicating the combination of antennas to use for communicating between said base station and said at least one wireless station is provided by said at least one wireless station transmitting feedback using the Responder Aggregation Control with additional information bits containing said information indicating the combination of antennas to use;
• wherein cyclic delay diversity (CDD) is supported by setting more than 1 antenna selection bit when an modulation coding scheme (MCS) rate <=54 Mbps is returned as feedback.

A machine accessible medium storing a machine program that provides instructions, which when accessed, cause a machine to perform operations comprising:

• adapting antenna use configurations used in wireless transmissions between wireless devices based on explicit feedback by at least one of said wireless devices;
• transmitting sounding packets by at least one other wireless device to said least one wireless device and wherein said at least one wireless device is capable of responding to said at least one other wireless device with information indicating the combination of antennas to use in communicating between said wireless devices;
• and
• transmitting feedback to said at least one other wireless device using a Responder Aggregation Control with additional information bits containing said information indicating the combination of antennas to use;
• wherein cyclic delay diversity (CDD) is supported by setting more than 1 antenna selection bit when an modulation coding scheme (MCS) rate <=54 Mbps is returned as feedback.
