Abstract

An efficient burst ACK method and apparatus in wireless communication environment are provided. An ACK frame transmission method whereby plural frames are received from a transmitting device and receipt of the frames is acknowledged with a single ACK frame includes receiving frames from the transmitting device and storing identification information of the received frames; generating a first field by recording a set of bit pairs to each of the received frames, with the use of the stored identification information; generating an ACK frame including the generated first field; and transmitting the generated ACK frame to the transmitting device, wherein a bit pair includes: a first bit to acknowledge whether any concerned frame is properly received; and a second bit to distinguish whether the first bit is to acknowledge receipt of the concerned frame from whether it is to acknowledge receipt of all the fragments following the concerned frame.

Description

technical field [0001] Devices and methods consistent with the present invention relate to wireless communications. More particularly, the present invention relates to a wireless communication method using a more efficient burst ACK. Background technique [0002] As wireless networks are becoming increasingly popular and there is an increasing demand for transmission of large amounts of multimedia data, more efficient transmission is required in wireless network environments. One of the characteristics of a wireless network is that several devices share and use a given wireless resource. According to this inherent characteristic, collisions in the transmission process with increasing contention tend to cause precious radio resources to be wasted. In order to reduce contention and send and receive data in a stable manner, contention-based distributed coordination function (DCF) and non-contention-based point coordination function (PCF) have been used...
