摘要： An apparatus and a method for controlling a data transmission rate in a broadband wireless communication system are provided. In the method, an interference factor representing an interference degree by an external sector is measured. Interference given to the external sector is estimated using the interference factor, an interference weight depending on a location of a terminal, and an amount of wireless resource use of a self sector. A data transmission rate is determined with consideration of an interference estimation value and a wireless channel state of the terminal.

摘要： An apparatus and method reduce power consumption in a broadband wireless communication system. A transmitting end apparatus that includes a plurality of transmit (Tx) antennas includes a control block, a Processor (DSP) block, a modem block, and at least one power controller. The control block determines a traffic amount based on an amount of used resources. The Digital Signal Processor (DSP) block performs scheduling by using a subset of Tx antennas and a subset of resources on a frequency axis if the traffic amount is less than a threshold. The modem block applies boosting to a signal transmitted using the subset of resources. And at least one controller turns off an operation of at least one power amplifier that corresponds to at least one Tx antenna that is not included in the subset of Tx antennas.

摘要： A system and method for adding a burst of a single-input multiple-output mode or collaborative spatial multiplexing mode to a frame in a spatial multiplexing system. A base station is configured to add a burst of a single-input multiple-output mode to a frame in a spatial multiplexing system. The system and method includes backing up a pilot pattern and a number of slots allocated for connections with terminals; releasing slots allocated for a burst; resetting a pilot pattern of a collaborative spatial multiplexing mode burst of the terminals: and recalculating the number of remaining slots; comparing the number of slots that can be additionally allocated to the single-input multiple-output mode with the number of slots released in the releasing step; and determining a transmission format.
