Abstract
In an aspect, a first access point (AP) receives from a second AP a first frame indicating a first guard interval for a transmission from the second AP to a station (STA). The transmission is scheduled during a transmission opportunity (TXOP) of the first AP. The first AP transmits to the second AP a second frame indicating a second guard interval for the transmission. The second guard interval is based on the first guard interval. In another aspect the first AP transmits to the second AP a first frame indicating a first guard interval. The first AP receives from the second AP a second frame indicating a second guard interval.
Claims20
A first access point (AP) comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the first AP to:
- transmit, to a second AP, a first frame comprising a request to establish a coordinated beamforming (Co-BF) agreement;
- receive, from the second AP and in response to the first frame, a second frame indicating that the second AP supports a first guard interval for the Co-BF agreement;
- transmit, to the second AP, a third frame indicating the first guard interval for a Co-BF transmission of the Co-BF agreement;
- and
- transmit, to a first STA associated with the first AP and using the first guard interval, a first physical layer protocol data unit (PPDU) for the Co-BF transmission.
A first access point (AP) comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the first AP to:
- receive, from a second AP, a first frame comprising a request to establish a coordinated beamforming (Co-BF) agreement;
- transmit, to the second AP and in response to the first frame, a second frame indicating that the first AP supports a first guard interval for the Co-BF agreement;
- receive, from the second AP, a third frame indicating the first guard interval for a Co-BF transmission of the Co-BF agreement;
- and
- transmit, to a first STA associated with the first AP and using the first guard interval, a first physical layer protocol data unit (PPDU) for the Co-BF transmission.
A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a first access point (AP), cause the first AP to:
- transmit, to a second AP, a first frame comprising a request to establish a coordinated beamforming (Co-BF) agreement;
- receive, from the second AP and in response to the first frame, a second frame indicating that the second AP supports a first guard interval for the Co-BF agreement;
- transmit, to the second AP, a third frame indicating the first guard interval for a Co-BF transmission of the Co-BF agreement;
- and
- transmit, to a first STA associated with the first AP and using the first guard interval, a first physical layer protocol data unit (PPDU) for the Co-BF transmission.
