System and method for transmitting data in wireless local area network
First Claim
1. A system for transmitting data in a wireless local area network (WLAN), comprising:
- a wireless station which, when a No Acknowledge (ACK) function of the WLAN is applied, transmits a No ACK request message based on a protection mechanism according to a frame transmission condition based on link status packet information which is transmitted from an upper layer; and
an access point for sequentially receiving a frame from the wireless station without a delay time depending on the No ACK request message transmitted from the wireless station.

Abstract
In a system and method for transmitting data in a wireless local area network (WLAN), the system includes: a wireless station which, when a No Acknowledge (ACK) function of the WLAN is applied, transmits a No ACK request message based on a protection mechanism according to a frame transmission condition based on link status packet information which is transmitted from an upper layer; and an access point for sequentially receiving a frame from the wireless station without a delay time depending on the No ACK request message received from the wireless station. The method comprises steps corresponding to the above functions of the wireless station and the access point of the disclosed system.

12. A method of transmitting data in a wireless local area network (WLAN), the method comprising the steps of:
-
when a No Acknowledge (ACK) function of a wireless station is applied, receiving link status packet information from an upper layer; transmitting, at the wireless station, a No ACK request message based on a protection mechanism according to a frame transmission condition based on the received link status packet information; and sequentially receiving a frame, which is transmitted from the wireless station, at an access point without a delay time depending on the No ACK request message transmitted from the wireless station. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method of transmitting data in a wireless local area network (WLAN), the method comprising the steps of:
-
after power is switched on, determining whether a time (T1) necessary for acquiring a link status (Link_Status) of the WLAN has expired; when the time (T1) necessary for acquiring the link status of the WLAN has expired, determining whether a time (T2) for determining data transmission/reception has expired; when the time (T2) for determining the data transmission/reception has expired, determining whether a receiver signal strength indicator (RSSI) value is not less than a threshold value; when the RSSI value is not less than the threshold value, determining whether a packet error rate is less than another threshold value; and when the packet error rate is less than said another threshold value, attempting a No Acknowledge (ACK) transmission. - View Dependent Claims (24, 25, 26, 27)
