WLAN TDM IFS time selection protocol
First Claim
1. A first wireless network device in a wireless network that includes a plurality of wireless network devices, the first wireless network device comprising:
- a radio frequency (RF) transceiver that transmits and receives data packets and that periodically transmits or receives a beacon; and
a control module that communicates with the RF transceiver, that determines a sequential transmission position m of the first wireless network device among the plurality of wireless network devices and a default interframe space (IFS) time based on the beacon, that selects a second IFS time when the RF transceiver receives a data packet from a second wireless network device having a sequential transmission position m−
1, and that selects the default IFS time when the RF transceiver does not receive a data packet from the second wireless network device.

Abstract
A first wireless network device in a wireless network that includes a plurality of wireless network devices comprises an RF transceiver that transmits and receives data packets and that periodically transmits or receives a beacon. A control module communicates with the RF transceiver, determines a transmission position m and a default IFS time based on the beacon, selects a second IFS time when the RF transceiver receives a data packet from a second wireless network device having a transmission position m−1, and selects the default IFS time when the RF transceiver does not receive a data packet from the second wireless network device.

18. A method for transmitting and receiving data with a first wireless network device in a wireless network that includes a plurality of wireless network devices, the method comprising:
-
transmitting and receiving data packets; periodically transmitting or receiving a beacon; determining a sequential transmission position m of the first wireless network device among the plurality of wireless network devices and a default interframe space (IFS) time based on the beacon; selecting a second IFS time when the first wireless network device receives a data packet from a second wireless network device having a sequential transmission position m−
1; andselecting the default IFS time when the first wireless network device does not receive a data packet from the second wireless network device. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
