An access point comprising physical layer (PHY) and medium-access control (MAC) layer circuitry configured to:
- contend for a wireless medium to receive exclusive control of the medium for a control period;
- transmit a control transmission at the beginning of the control period, the control transmission to identify at least two stations;
- and
- communicate with identified stations in accordance with a non-contention based multiple-access technique during the control period.
A communication station (STA) comprising physical layer (PHY) and medium-access control (MAC) layer circuitry configured to:
- receive, from an access point, a control transmission indicating a beginning of the control period, the control period comprising a transmission opportunity (TXOP), the control transmission to identify at least two stations;
- and
- when the STA is identified in the control transmission, the STA is arranged to communicate with the access point in accordance with a non-contention based multiple-access technique during the control period,
- wherein during the control period, one or more other stations identified in the control transmission communicate with the access point in accordance with the non-contention based multiple-access technique.
A method performed by an access point comprising:
- contending for a wireless medium to receive exclusive control of the medium for a control period;
- transmitting a control transmission at the beginning of the control period, the control transmission to identify at least two stations;
- and
- communicating with identified stations in accordance with a non-contention based multiple-access technique during the control period.
A method performed by a communication station (STA) comprising physical layer (PHY) and medium-access control (MAC) layer circuitry configured to:
- receive, from an access point, a control transmission indicating a beginning of the control period, the control period comprising a transmission opportunity (TXOP), the control transmission to identify at least two stations;
- and
- when the STA is identified in the control transmission, the method includes communicating with the access point in accordance with a non-contention based multiple-access technique during the control period,
- wherein during the control period, one or more other stations identified in the control transmission communicate with the access point in accordance with the non-contention based multiple-access technique.
A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of an access point to perform operations comprising:
- contending for a wireless medium to receive exclusive control of the medium for a control period;
- transmitting a control transmission at the beginning of the control period, the control transmission to identify at least two stations;
- and
- communicating with identified stations in accordance with a non-contention based multiple-access technique during the control period.
