    摘要： Provided is a communication method and a data frame for a communication system having a relay station. An uplink sub-frame of the data frame may include a first uplink relay sub-frame which corresponds to a time frame where relay stations selected among a plurality of relay stations simultaneously transmit uplink relay signals to a base station, and a second uplink relay sub-frame which corresponds to a time frame where the remaining relay stations transmit remaining uplink relay signals to the base station using a scheduled radio resource. A downlink sub-frame of the data frame may include a first downlink relay sub-frame which corresponds to a time frame where a base station simultaneously transmits downlink relay signals to relay stations selected from among a plurality of relay stations, and a second downlink relay sub-frame which corresponds to a time frame where the base station transmits remaining downlink relay signals to the remaining relay stations using a scheduled radio resource.

    摘要： A multi-band scheduling method determines frequency bands for each of a plurality of frames existing in a single session queue from among a plurality of frequency bands based on data characteristics of each of the plurality of frames. In particular, the multi-band scheduling method may assign a frame with a high significance to a frequency band having a superior channel state, thereby increasing communication reliability. Also, a broadcasting service system may use the multi-band scheduling method to effectively provide the broadcasting services.

    摘要： An encryption key distribution method capable of performing fast roaming by differentially distributing encryption keys in advance, according to access authorization classes, in a wireless access network and a roaming method using distributed encryption keys are provided. The encryption key distribution method comprises: receiving a command to communicate with an access point not available for communication using an encryption key currently selected in the encryption key set; determining access authorization of the access point not available for communications; selecting an encryption key from the encryption key set obtained in advance corresponding to the determined access authorization; and using the selected encryption key to encrypt a transmission message and communicate with the access point not available for communication. The method reduces the delay time, which is caused by encryption key distribution while a wireless terminal is traveling, such that roaming and a hand-off are carried out quickly and safely, and user convenience and safe transmission of data are achieved.

    摘要： A system is provided for efficiently allocating a transmission period in a wireless network system. An access point (AP) transmits a PSMP frame indicating a downlink period provided to each station (STA) and a minimum amount of an uplink period allocated to each STA, and at least one sub PSMP frame indicating an uplink period additionally provided for an STA that transmitted a resource request message for remaining queued data in the uplink period indicated by the PSMP frame. If the uplink period indicated by the PSMP frame is insufficient to transmit the queued data, the STA transmits a data unit including a part of the queued data and a resource request message for the remaining queued data in the uplink period. After transmitting the resource request message, the STA receives the sub PSMP frame after the full period indicated by the sub PSMP frame, and transmits the remaining queued data to the AP in the uplink period indicted by the sub PSMP frame.
