Time Slot Request And Allocation Method in Wireless LAN Apparatus Using TDMA/TDD MAC Protocol

摘要

The present invention relates to a bandwidth request and a bandwidth allocation method in a WLAN bridge apparatus using a TDMA / TDD MAC protocol.;According to the present invention, a time division multiple access (TDMA) field includes a map field, a downlink field, an uplink field, and a slave medium access control (MAC) message (hereinafter, referred to as 'smm') field. ) / A plurality of second WLANs in which a first WLAN bridge device (hereinafter, referred to as a “master”) connected to an IP core network is connected to a base station in a WLAN bridge device using a TDD (Time Division Duplex) MAC protocol. In the method for allocating a section for a bandwidth request of a bridge device (hereinafter, referred to as a slave), the master includes an ACK transmission section and a wireless relay network in which a slave, which has downloaded data from the downlink field, transmits ACK information. A wireless LAN to which the MAC protocol of the TDMA / TDD scheme is divided and set by dividing the SMM field into a bandwidth request SMM transmission interval in which an access slave transmits bandwidth request information. A band allocation method in a ridge device is provided.;According to the present invention, it is possible to provide a higher data rate and stability than the conventional WLAN bridge technology, and there is an effect of smoothly transmitting a large amount of traffic. In addition, it can contribute to improving service quality for wireless Internet users, including public wireless LAN or Wibro, and reducing service provider's network construction cost.;WLAN, bridge, TDMA, TDD, MAC, band, allocation
