摘要： An apparatus and method are provided for transmitting data in a station of a wireless local area network (LAN) system. In the apparatus, a data queue stores transmission data, and a data processor processes data output from the data queue. A radio frequency (RF) module up-converts a signal output from the data processor to a frequency band of the wireless LAN system, and transmits the up-converted signal as an RF signal. A scheduler performs scheduling such that a specific stepping index decreases each time a backoff time reaches ‘0’ so as to determine whether to transmit the data, and the data is transmitted when both the stepping index and the backoff time reach ‘0’. A backoff stepping generator determines an initial value of the stepping index within a predetermined range.

摘要： A method and apparatus perform channel scanning in a wireless communication system. A signal intensity of an Access Point (AP) is compared with a scanning threshold, when the AP signal intensity not less than the scanning threshold, a channel scanning schedule list is generated in consideration of a scan time based on a passive channel scan scheme and a scan time based on an active channel scan scheme. The channel scanning is performed every channel scanning time, according to the channel scanning schedule list.

摘要： An apparatus and method provide effective video transmission in a communication system that supports an Internet Protocol Television (IPTV) service between heterogeneous networks. A request for a contiguous service is received from a terminal during a mid-point of a video stream. A delay time that may be generated when the video contents are transmitted is estimated for each of a patching type and a fast broadcasting type. A transmission type with a shorter delay time for the video contents is determined based on the estimated delay time for each of the patching type and the fast broadcasting type. And the video contents are transmitted to the terminal by applying the determined transmission type.
