Re-transmitting packet of polling-based wireless local area network (WLAN)
First Claim
1. A method comprising:
- scheduling a super frame to form a first period of providing a polling message to arbitrary stations at an Access Point (AP) and allowing only stations receiving the polling message to get access to a medium without contention, and to form a second period of allowing the stations to get access to the medium through contention;
transmitting packets stored in a first transmission queue to the corresponding stations during the first period of the super frame; and
enqueuing a packet whose transmission results in failure during a first portion of a second transmission queue to re-transmit the packet whose transmission has resulted in failure during the second period upon a determination that at least one of the packets transmitted to the stations has resulted in a failure to be transmitted.

Abstract
A method of re-transmitting a packet of an access point (AP) in a polling-based Wireless Local Area Network (WLAN) includes: scheduling a super frame to form a first period of providing a polling message to arbitrary stations at the AP and allowing only stations receiving the polling message to get access to a medium without contention, and to form a second period of allowing the stations to get access to the medium through contention; transmitting packets stored in a first transmission queue to the corresponding stations during the first period of the super frame; and enqueuing a packet whose transmission results in failure during a first portion of a second transmission queue to re-transmit the packet whose transmission has resulted in failure during the second period upon a determination that at least one of the packets transmitted to the stations has resulted in a failure to be transmitted.
