    摘要: A wireless communication system including transmitters for determining a transmission rate for an associated receiver according to channel state information fed back from associated receivers, and transmitting packets at the determined transmission rate. In a communication method, a transmitter groups packets to be transmitted to the receivers according to transmission rates, and generates frames configured by packets with an identical transmission rate. The transmitter aggregates frames with different transmission rates into one transmission burst, and sends the transmission burst. The data communication method based on packet aggregation can efficiently manage resources by determining transmission rates for reception stations (STAs) on the basis of feedback channel state information in a transmission STA, aggregating packets to be transmitted to the reception STAs to form a packet group, and transmitting packet groups with different transmission rates using one multi-rate aggregation (MRA) burst.

    摘要: A method and apparatus for estimating available throughput of a fixed node in a mobile node of a communication network. The communication network includes fixed nodes connected to a router connected to at least one foreign network and mobile nodes connected to the fixed nodes. A second mobile node is selected from among mobile nodes connected to a fixed node whose available throughput is estimated in a first mobile node. An idle slot interval of the second mobile node connected to the fixed node is set. A transmission probability is measured in one slot interval of the second mobile node through an average of set idle slot intervals. Transmission information of the second mobile node is acquired using the measured transmission probability. The available throughput of the fixed node is estimated using the acquired transmission information.

    摘要: A scheduling apparatus for a base transceiver system (BTS), determines a point of data transmission to mobile stations (MSs). The BTS includes buffers for storing data to be transmitted to the MSs. A scheduler determines a priority of each of the MSs taking into account a data rate determined depending on a channel condition between the BTS and the MSs, a required amount of transmission data, and an amount of data to be transmitted to the MSs, and determines an MS having the highest priority among the MSs, as a destination MS to which data is to be transmitted by the BTS. The scheduler increases the required amount of transmission data upon receipt of a retransmitted data packet, and decreases the required amount of transmission data after transmitting data to the MSs.

    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.
