Abstract
An asymmetric handshaking design between an access point (AP) and a station (STA) is introduced. An access point is controlled to transmit packets in a first packet format. In response to packets transmitted from the access point in the first packet format, a station is switched to use a second packet format to transmit packets to form asymmetric handshaking with the access point when the station fails to use the first packet format to answer the access point.
Claims25
A wireless device, comprising:
- a transmitter and a receiver;
- and
- a controller, controlling the transmitter and the receiver, wherein:
- in response to packets transmitted from an access point in a first packet format and received by the receiver, the controller switches the transmitter to use a second packet format to transmit packets to form asymmetric handshaking with the access point when there has been a failure to answer the access point by the first packet format.
1 more element
A wireless device, comprising:
- a transmitter and a receiver;
- and
- a controller, controlling the transmitter and the receiver,
- wherein:
- the controller controls the transmitter to keep using a first packet format to transmit packets when the receiver receives packets transmitted from a station in a second packet format, to form asymmetric handshaking with the station.
2 more elements
A wireless communication method, comprising:
- controlling an access point to transmit packets in a first packet format;
- and
- in response to packets transmitted from the access point in the first packet format, switching a station to use a second packet format to transmit packets to form asymmetric handshaking with the access point when the station fails to use the first packet format to answer the access point,
- wherein:
- the second packet format provides a wider coverage boundary than the first packet format;
- in comparison with the second packet format, the first packet format is compatible with older wireless communication protocols;
- and
- in comparison with the second packet format, a higher data rate is provided by the first packet format.
