Abstract:
A method and apparatus are provided for controlling a data rate in a mobile communication system. The method includes changing an offset from a first offset used in a previous packet to a second offset determined based on whether or not the previous packet is successfully received by a second apparatus; determining whether or not a second channel quality in which the second offset is applied is within a range from a minimum quality to a maximum quality; if it is determined that the second channel quality is not within the range, determining that the offset is maintained as the first offset in a current packet; and transmitting, to the second apparatus, the current packet according to a first channel quality in which the first offset is applied.

Abstract:
A method for mitigating inter-cell interference by a base station in a cellular communication system. The base station determines cells to which same frequency resources are allocated, and which cause interference to each other, and determines a starting time slot, at which resource allocation to each cell starts, as a different time slot for each cell, taking into account a number of the cells and time slots constituting time resources. In response to receiving a call setup request from a terminal, the base station selects a time slot taking into account interference information of each of the time slots, and allocates a resource based on the selected time slot to the terminal.
Abstract:
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.

Abstract:
An apparatus and a method are provided for allocating resources, in which a base station allocates a time slot to a terminal in a wireless communication system supporting a time division multiple access scheme. The method includes a monitoring block of monitoring a channel state of the terminal after allocating a time slot for the terminal. The method also includes adjusting, by increasing or reducing, the number of the existing allocated time slots when the channel state of the terminal satisfies a preset time slot adjustment requirement.
Abstract:
A method for managing pairing between a plurality of mobile stations sharing one time slot in a wireless communication system is provided. The method includes selecting candidate mobile stations to share one time slot. The method also includes checking an occurrence of power racing using a code rate and an availability of the candidate mobile stations. The method further includes determining whether to perform pairing that enables the candidate mobile stations to share the one time slot, based on results from checking the occurrence of the power racing.
