Wireless network system and method for transmitting and receiving data in the wireless network
First Claim
1. A wireless network coordinator in a wireless network system, the wireless network coordinator comprising:
- a media access control unit which generates a beacon frame of a superframe, the superframe comprising at least one channel time block and the beacon;
a bandwidth management unit which sets a specific channel time block among the at least one channel time block to a time period during which a packet for a beam search is transmitted and received among stations in a network, during a setting; and
a transmission unit which transmits the beacon frame comprising information on the setting through a predetermined communication channel.

Abstract
Provided is a wireless network system and a method for transmitting and receiving data in the wireless network, which have a particular time period for a beam search in a superframe thereof in order to enable stations, which carry out directional communications with a high frequency bandwidth, to efficiently perform a beam search. A wireless network coordinator in the wireless network system includes a media access control unit generating a beacon frame which constitutes a superframe including at least one channel time block; a bandwidth management unit setting a specific channel time block among the channel time blocks to a time period during which a packet for a beam search is transmitted and received among stations in a network; and a transmission unit transmitting the beacon frame having information on the setting through a predetermined communication channel.

10. A station for transmitting and receiving data in a wireless network system, the station comprising:
-
a media access control unit which generates a packet which requests bandwidth allocation in a specific channel time block among one or more channel time blocks of a superframe; and a transmission unit which transmits a packet which requests a beam search through a designated communication channel in the specific channel time block when the bandwidth allocation has been performed in response to the packet which requests bandwidth allocation. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

28. A method of transmitting and receiving data among stations in a wireless network system, the method comprising:
-
generating a first packet which requests bandwidth allocation in a specific channel time block among one or more channel time blocks of a superframe; transmitting the first packet produced in the generating; and transmitting a second packet which requests a beam search through a designated communication channel in the specific channel time block when the bandwidth allocation has been performed in response to the transmitted first packet. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36)
