  • Publication number: 20110183679
    Abstract: A method and apparatus for controlling inter-cell interference in an evolved Node-B for a cellular communication system with a frequency reuse factor of 1 are provided. The apparatus includes a bitmap generator for receiving scheduling information from evolved Node-Bs of a plurality of neighbor cells, and for generating scheduling information including its cell's bitmap information for the resource allocation using the received neighbor cells' scheduling information, and a scheduler for scheduling the resource allocation for UEs in its cell based on the scheduling information provided from the bitmap generator and power allocation information of the UEs in its cell.

  • Patent number: 7720503
    Abstract: A method for controlling power in a communication system. In the power control method, a transmitter receives feedback information from receivers located in its own cell; determines data rates of the receivers according to the received feedback information, calculates a load of the cell by calculating an amount of data to be transmitted to the receivers; and calculates transmission power of the transmitter by comparing the load of the cell with a threshold.

  • Publication number: 20090196273
    Abstract: An apparatus and a method for a random access scheme for multi-channel in a wireless communication system are provided. The method for performing the random access scheme for the multi-channel in the wireless communication system includes randomly generating a backoff counter value to transmit data; adjusting the backoff counter value by taking into account status of a plurality of idle subcarrier sets per backoff slot; when the backoff counter value becomes zero, selecting one or more subcarrier sets to carry the data from the idle subcarrier sets; and transmitting the data through the selected one or more subcarrier sets. The data collision probability between the terminals can be lowered, the channel utility can be enhanced, the transfer rate in the single-channel random access scheme can be raised, and the consumption of the radio resource can be reduced without using signals for the band request and allocation.

  • Publication number: 20050163072
    Abstract: A packet scheduling method using a cumulative distribution function. The scheduling method for use in a communication system including a plurality of MSs (Mobile Stations) and a central controller for assigning resources to individual MSs on the basis of a transmission rate associated with downlink channels fed back from the MSs, includes the steps of generating a uniform random variable of transmission rates of individual MSs; converting the uniform random variable into a scheduling priority; comparing the scheduling priority of each MS with each other; and assigning resources to a MS having the highest scheduling priority.
