Abstract
A wireless network communication device comprises a host processor, a network interface coupled to the host processor and comprising a transceiver operable to generate and transmit a control message frame. The control message frame includes: a short training field, a long training field, and a signal field including modulation and coding scheme subfield to hold message type information, transmitter address information, receiver address information, and frame check sequence information.

A method comprising:
- generating a control message frame comprising a signal field (SIG) to instruct the end a contention-free period;
- and
- wirelessly transmitting the control message frame.

A method of restricted access window operation in a wireless network, the method comprising:
- initiating a restricted access window channel access operation;
- and
- generating and transmitting a CF-End message frame at an access point to one or more client stations in response to an instruction to end restricted access window channel access operation.
A method of restricted access window operation in a wireless network, the method comprising:
- initiating a restricted access window channel access operation;
- and
- generating and transmitting a CF-End+CF-Ack message frame at an access point to one or more client stations in response to an instruction to acknowledge a prior message and end restricted access window channel access operation.
A method of restricted access window operation in a wireless network, the method comprising:
- initiating a restricted access window channel access operation;
- and
- generating and transmitting a CF-End message frame at a client station in response to no more data to send and to trigger downstream transmission from an access point.
A method of restricted access window operation in a wireless network, the method comprising:
- initiating a restricted access window channel access operation;
- and
- generating and transmitting a CF-End+CF-Ack message frame at a client station in response to acknowledging a prior message and no more data to send, and to further trigger downstream transmission from an access point.
