Abstract
A method and apparatus for exchanging antenna capability information between a transmitting station (STA) and a receiving STA in a wireless communication system may include an antenna capability information element (IE) that includes information regarding the capability of the transmitting STA. The antenna capability IE may be transmitted from the transmitting STA to the receiving STA prior to data transmission between the transmitting STA and the receiving STA. When used in a wireless local area network, the antenna capability IE may be transmitted as part of a management frame, control frame, or data frame.
Claims24
A first 802.11 station (STA) for exchanging antenna capability information in wireless communications, the first 802.11 STA comprising:
- a receiver configured to receive a probe request frame that contains an antenna capability information element that indicates a number of supported beams of a second 802.11 STA;
- and
- a transmitter configured to transmit a probe response frame that contains a second antenna capability information element that indicates a number of supported beams of the first 802.11 STA.
A method for exchanging antenna capability information at a first 802.11 station (STA) in wireless communications, the method comprising:
- receiving a probe request frame that contains an antenna capability information element that indicates a number of supported beams of a second 802.11 STA;
- and
- transmitting a probe response frame that contains a second antenna capability information element that indicates a number of supported beams of the first 802.11 STA.
A method for exchanging antenna capability information at a first 802.11 station (STA) in wireless communications, the method comprising:
- transmitting a probe request frame containing an antenna capability information element relating to an antenna capability of the first 802.11 STA, prior to data transmission with a second 802.11 STA, wherein the antenna capability information element indicates a number of supported beams;
- receiving a probe response frame containing an antenna capability information element relating to an antenna capability of the second 802.11 STA;
- and
- determining which antenna capabilities to use for future transmission and reception.
