    摘要： Provided is a method and apparatus for distributed transmission power control in a wireless network. The method and apparatus for distributed transmission power control may substantially maximize a minimum value of a transmission rate of each transmitter by controlling a transmission power of each transmitter. The transmission power may be controlled so that transmission rates of transmitters are substantially identical to each other. If the transmission rate is less than a requested transmission rate, the method and apparatus may change a resource of a transmitter that uses a substantially maximum power.

    摘要： In the data transmission method, a MAC layer receives data from an upper layer, classifies the data according to destination addresses and traffic identifiers, aggregates the data by destination address and traffic identifier as a first transmission unit, aggregates the first transmission units having the identical destination address as a second transmission unit, and transmits the second transmission units having different destination addresses in a single frame. The data transmission method allows packets transferred from the upper layer to be hierarchically aggregated by DAs and TIDs and then packaged into a data unit for each destination such that it is possible to transmit the data at an optimal data rate for each destination terminal.

    摘要： A communication system performs an uplink communication and a downlink communication using respective radio resources that at least partially overlap each other in both time and frequency, which may cause interference to occur in at least one downlink terminal due to at least one uplink terminal. The at least one uplink terminal and the at least one downlink terminal may process the interference according to a rate split scheme, an interference control scheme, and the like. Interference occurring between at least one transmit antenna and at least one receive antenna of a base station may be processed according to an echo cancellation scheme and the like.

    摘要： A system to cooperatively control inter-cell interference is provided. A first frequency allocated to a central area of a serving cell associated with a serving base station may be allocated to a central area of a neighboring cell associated with a neighboring base station. A second frequency allocated to an edge area of the serving cell may be allocated to an edge area of the neighboring cell. Where a terminal is located in the edge of the neighboring cell, scheduling information, channel information, and data may be exchanged between the terminal and the serving base station.

    摘要： A terminal receives a unique sequence from each of at least two base stations, and transmits a mixture of quantized unique sequences to a serving base station. The serving base station extracts components respectively corresponding to base stations from the mixture of the quantized unique sequences, and estimates a location of a terminal based on the extracted components. The serving base station may calculate a received signal strength or a delay for each of the unique sequences received by the terminal, based on the extracted components, and estimate the location of the terminal based on the received signal strength or the delay. In addition, the terminal may estimate its own location by performing an algorithm used by the serving base station.
