Abstract
A first access point (AP), which is associated with one or more first client stations, receives an announcement frame from a second AP that is associated with one or more second client stations. The announcement frame announces a coordinated multi-user (MU) transmission involving at least the first AP and the second AP, includes an indicator of a frequency resource unit (RU) allocated to the first AP for the coordinated MU transmission. The first AP participates in the coordinated MU transmission using the frequency RU indicated by the announcement frame while the second AP also participates in the coordinated MU transmission.
Claims24
A method for wireless communication by a first access point (AP) associated with one or more first client stations, the method comprising:
- receiving, at the first AP, an announcement frame from a second AP associated with one or more second client stations, the announcement frame announcing a coordinated multi-user (MU) transmission involving at least the first AP and the second AP, wherein the announcement frame includes an indicator of a frequency resource unit (RU) allocated to the first AP for the coordinated MU transmission;
- and
- participating, by the first AP, in the coordinated MU transmission using the frequency RU indicated by the announcement frame while the second AP also participates in the coordinated MU transmission.
A first access point (AP) associated with one or more first client stations, the first AP comprising:
- a wireless network interface device comprising one or more integrated circuit (IC) devices configured to:
- receive an announcement frame from a second AP associated with one or more second client stations, the announcement frame announcing a coordinated multi-user (MU) transmission involving at least the first AP and the second AP, wherein the announcement frame includes an indicator of a frequency resource unit (RU) allocated to the first AP for the coordinated MU transmission, and
- control the wireless network interface device to participate in the coordinated MU transmission using the frequency RU indicated by the announcement frame while the second AP also participates in the coordinated MU transmission.
